Description
COMPOSITIONS AND METHODS FOR THE TREATMENT OF HEMOGLOBINOPATHIES AND THALASSEMIAS
RELATED APPLICATIONS
This application daims priority to U.S. Serial No. 62/687721 filed June 20, 2019 and to U.S. Serial No. 62/804879 filed February 13, 2019, the contents of which is incorporated herein by reference in its entirety.
BACKGROUND
Hemoglobinopathies, such as sickle cell disease, are highly prévalent genetic érythrocyte disorders that cause a significant health burden worldwide. Hemoglobinopathies encompass a number of anémias of genetic origin in which there is a decreased production and/or increased hemolysis of érythrocytes. In particular, sickle cell disease is a group of genetic disorders that manifest in the production of sickle-shaped érythrocytes and are characterized by hemolytic anémia and vaso-occlusion events in addition to intense periods of pain, organ failure, and early mortality. Sickle cell anémia is the most common and severe form of sickle cell disease (SCD), affecting approximately 100,000 people in the United States and 4.4 million worldwide. For many patients, SCD is defmed by chronic organ failure punctuated by acute complications and early mortality. Current thérapies for SCD are limited to supportive treatment of complications, érythrocyte transfusions, hydroxyurea, and stem cell transplantation.
Given the lack of available thérapies, there is still a need for agents, e.g., dietary compositions and therapeutics for treating hemoglobinopathies, such as SCD, in a subject.
SUMMARY OF THE INVENTION
Provided herein is a composition (e.g., an Active Moiety) including amino acid entities that is useful for improving érythrocyte and/or hemoglobin function, turnover, and synthesis; vascular function; inflammation; and/or oxidative stress in a subject, e.g., a subject with a hemoglobinopathy (e.g., sickle cell disease) or a thalassemia (e.g. α-thalassemia or β-thalassemia). The composition can be used in a method of treating (e.g., reversing, reducing, ameliorating, or preventing) one or more symptoms of a hemoglobinopathy or a thalassemia in a subject in need thereof (e.g, a human). The method can further include monitoring the subject for an improvement in one or more symptoms of a hemoglobinopathy or a thalassemia after administration of the composition.
In one aspect, the invention features a method of improving one, two, three, four, five, six or more (e.g., ail) of érythrocyte function, turnover, or synthesis; hemoglobin function, turnover, or synthesis; or vascular function, comprising administering to a subject in need thereof an effective amount of a composition (e.g., an Active Moiety) comprising:
a) a leucine amino acid entity,
b) a arginine amino acid entity,
c) glutamine amino acid entity; and
d) a N-acetylcysteine (NAC)-entity;
the composition does not comprise a peptide of more than 20 amino acid residues in length (e.g., whey protein), or if a peptide of more than 20 amino acid residues in length is présent, the peptide is présent at less than: 10 wt. % of the total wt. of the composition (e.g., in dry form);
thereby improving one, two, three, four, five, six or more (e.g., ail) of érythrocyte function, turnover, or synthesis; hemoglobin function, turnover, or synthesis; or vascular function in the subj ect.
In another aspect, the invention features a method of improving érythrocyte function comprising administering to a subject in need thereof an effective amount of the composition described herein.

DETAILED DESCRIPTION
Physical and metabolic dysfimction of red blood cells (RBC) drive acute and chronic complications in nearly every organ System, such as in a hemoglobinopathy (e.g., sickle cell disease) or a thalassemia (e.g. α-thalassemia or β-thalassemia). RBC dysfunction and lysis drive myriad clinical sequelae such as vaso-occlusion, organ failure, and infections. RBC dysfunction can be characterized by cell sickling, oxidative stress, déhydration, and adhesion to endothélium, which may complicate the passage of RBC through microvessels. Chronic complications can stem from a lifetime of anémia and accrual of organ damage into adulthood, and can be punctuated by acute events such as vaso-occlusion and sudden organ failure.
Sickle cell disease (SCD) describes a group of serious blood disorders that affect some 85,000 adults and 15,000 children in the US, and 4.4 million individuals worldwide. The sickleshaped red blood cells that are the hallmark of SCD reveal only a small fraction of the complex and multifactorial pathophysiology stemming from perturbations in the normal function of blood and the vascular system. Current care is limited both in scope and magnitude of effect, leaving an unmet need for agents that help to mitigate the multifaceted complications arising from blood and vascular dysfunction.
The compositions of the invention are designed to target multiple pathways (blood production and integrity, vascular function, and plasma and RBC amino acid imbalances) intersecting key Systems (vascular, RBCs) to maintain blood health and fonction.
The amino acid entities and relative amounts of the amino acid entities in the compositions disclosed herein hâve been optimized, e.g., to [1] reduce vascular adhesion, [2] mitigate the présentation of vascular inflammation, [3] defend against insults to red blood cell (RBC) deformability and function, and reduce complications associated with SCD (e.g., hemolysis, vascular adhesion, vascular inflammation, reduced vascular function, acute and chronic organ failure) in a subject that requires the coordination of many biological, cellular and molecular processes. Without being bound by any theory, it is understood that a composition of the invention can reprogram the disordered multifactorial biology of [1] RBC rigidity and fragility, [2] hemolysis, [3] vascular adhesion, [4] vascular inflammation, and [5] vascular dysfunction.
The composition described herein provides a multimodal and combinatorial approach to improve red blood cell dysfunction, hemolysis (e.g., including anémia, chronic hypoxia, oxidative stress, déplétion of nitric oxide, and/or vascular dysfunction), vaso-occlusion (e.g., including ischémie injury, inflammation, clotting, and/or acute organ damage), altered hematopoiesis, and/or sickle cell disease pathophysiology. In some embodiments, administration of the composition results in improved vascular tone, vascular dilation, and/or vaso-occlusion (e.g. improved NO availability, NO-dependent endothélial function, and/or blood pressure). In some embodiments, administration of the composition results in improved RBC deformability, reduced hemolysis, and/or reduced vascular inflammation (e.g., as determined by levels of glutathione (e.g., plasma or RBC glutathione), oxidative stress markers, hemolytic markers, cytokines, and/or adhesion markers). In some embodiments, administration of the composition results in increased protein synthesis and/or increased proteogenic substrates for hemoglobin to support heme synthesis. In some embodiments, administration of the composition results in improved hematopoiesis and/or an improved red blood cell population (e.g. improved réticulocytes, hemoglobin, fêtai hemoglobin, and/or dense or irreversibly sickled cells). The composition described herein is optimized to target one, two, or three of: (i) restoration of plasma arginine and nitric oxide to improve vascular injury; (ii) improved antioxidant defense in red blood cells, plasma, and systems-wide; or (iii) anabolic and energetic support for increased hematopoietic demand, in a subject, e.g., a subject having a hemoglobinopathy (e.g., sickle cell disease) or a thalassemia (e.g. α-thalassemia or β-thalassemia).
In some embodiments, the composition (e.g., the Active Moiety) is capable of improving one, two, three, four, or more (e.g., ail) of NO-mediated vascular function, protein synthesis, cellular energy, inflammation, or heme synthesis. In some embodiments, the composition is capable of restoring NO-dependent endothélial function, reducing risk of vaso-occlusion events, improving vascular health, decreasing hemolysis, and/or decreasing oxidative stress. In some embodiments, the composition is capable of providing increased arginine bioavailability for NO synthesis. In some embodiments, the composition is capable of increasing RBC turnover, protein synthesis (e.g., hemoglobin synthesis, e.g., in hematopoietic progenitors and/or réticulocytes), and/or heme synthesis. In some embodiments, the composition is capable of providing energetic support for highly proliférative cells (e.g., hematopoietic precursors and/or immune cells).
Described herein, in part, is a composition (an Active Moiety) comprising amino acid entities and methods of improving one, two, three, four, five, six, seven, eight or more (e.g., ail) of érythrocyte function, turnover, or synthesis; hemoglobin function, turnover, or synthesis; vascular function; oxidative stress (e.g., one or both of blood and systemic oxidative stress); or inflammation by administering an effective amount of the composition. The composition may be administered to treat a hemoglobinopathy (e.g., sickle cell disease) or a thalassemia (e.g. α-thalassemia or βthalassemia) in a subject in need thereof. The amino acid entities and relative amounts of the amino acid entities in the composition hâve been carefiilly selected, e.g., to improve érythrocyte and/ or hemoglobin function, turnover, or synthesis in a subject (e.g., a subject having a hemoglobinopathy (e.g., SCD) or a thalassemia) that requires the coordination of many biological, cellular, and molecular processes. The composition allows for multi-pathway bénéficiai effects on the systemslevel pathology of a hemoglobinopathy or a thalassemia. In particular, the composition has been specifïcally tailored to treat oxidative stress, vascular disease, inflammation, and the increased turnover, synthesis, and dysfunction of érythrocytes and hemoglobin.
Complex diseases, such as hemoglobinopathy (e.g., sickle cell disease) or thalassemia (e.g. α-thalassemia or β-thalassemia), impact multiple biological pathways. Loss of health can be the direct resuit of metabolic pathways and functions that are not being maintained or supported. Consequently, restoring homeostasis and maintaining health requires multifactorial approaches. The compositions described herein are interventional candidates to address the systems-wide impact of dysregulated metabolism to support and maintain homeostasis, which helps support normal structures and functions of the body.
The composition described herein hâve been optimized to directly and simultaneously target multiple metabolic pathways implicated both in complex diseases (e.g., a subject having a hemoglobinopathy (e.g., SCD) or a thalassemia) and overall health. The distinct ratios of each of the amino acid entities in the composition are designed to target and maximize the fundamental rôle of the composition in regulating multiple metabolic functions (e.g., one, two, three, four, five, six, seven, eight or more (e.g., ail) of érythrocyte function, turnover, or synthesis; hemoglobin function, turnover, or synthesis; vascular function; oxidative stress (e.g., one or both of blood and systemic oxidative stress). In particular, the composition described herein can support and maintain blood health, which is critical to a multitude of metabolic functions throughout the body.The composition described herein has been designed to target multiple biological pathways with the goal of supporting normal structures and functions of the blood. In particular, administration of the composition described herein can improve and/or treat one, two, three, or more of reduced blood production, reduced blood integrity, plasma and/or RBC amino acid imbalance, decreased vascular health, or inflammation, e.g., in a subject with a hemoglobinopathy (e.g., sickle cell disease) or a thalassemia (e.g. α-thalassemia or β-thalassemia). In some embodiments, administration of the composition to a subject improves or maintains one, two, three, four, five, six, seven, eight, or more of the following: (a) prolifération and/or maturation of blood cells during hematopoietic demand; (b) RBC form and/or function against déhydration; (c) rigidity; (d) oxygen transport; (e) amino acid balance to support RBC metabolism (e.g., substrates for glutathione and nitric oxide synthesis); (f) génération of ROS; (g) delivery of amino acids to peripheral tissue; (h) defenses against vascular adhesion; (i) inflammation; or (j) stasis.

Blending Techniques
The methods disclosed herein comprise blending steps which blend and mix combinations of pharmaceutical grade amino acid entities to create PGDBPs that meet a reference standard. Blending conditions used by the methods described herein may utilize any known blending mechanism or combination of blending mechanisms. Blending mechanisms include convection, diffusion, and shear. Convective blending utilizes gross motion of particles, e.g., by gentle rotation within a blender/mixer. Diffusion is the slow, passive blending of particles. Shear blending pushes part of a combination of particles in one direction and another part of the combination of particles in another direction along the same parallel plane. Blending conditions used by the methods described herein may further comprise the use of granulators or other equipment to modify the size and/or shape of particles of combination components (e.g., pharmaceutical grade amino acid entities).
In some embodiments, the blending or blending condition employed by a method disclosed herein comprises convective blending. In some embodiments, the blending or blending condition employed by a method disclosed herein comprises diffusion blending. In some embodiments, the blending or blending condition employed by a method disclosed herein comprises shear blending. In some embodiments, the blending or blending condition employed by a method disclosed herein comprises convective and diffusion blending. In some embodiments, the blending or blending condition employed by a method disclosed herein comprises convective and shear blending. In some embodiments, the blending or blending condition employed by a method disclosed herein comprises diffusion and shear blending. In some embodiments, the blending or blending condition employed by a method disclosed herein comprises convective, diffusion, and shear blending.
Blending conditions used by the methods described herein may utilize any known blending or mixing equipment; blending or mixing equipment may operate based on one or more blending mechanisms. There are four main types of blending or mixing equipment: convective, hoppers (i.e., gravimétrie), tumblers, and fluidization. In some embodiments, a blending condition or blending step of a method described herein may utilize one or more (e.g., 1, 2, 3, or 4) types of blending or mixing equipment. In some embodiments, dry blended préparations (e.g., PGDBPs) are prepared in batches. In some embodiments, dry blended préparations (e.g., PGDBPs) are prepared in a continuons fashion, e.g., harvesting blended/mixed préparation without interrupting blending or mixing.
The blending or mixing steps of methods disclosed herein are of duration sufficient to produce a dry blended préparation, e.g., PGDBP, which meets a reference standard. In some embodiments, the duration of the blending condition is at least 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 75, 90, 105, or 120 minutes.

In some embodiments, the duration of the blending condition is sufficient that blending and mixing does not introduce heterogeneity into the combination or dry blended préparation, e.g., by over-mixing. In some embodiments, the duration of the blending condition is determined by évaluation of whether a reference standard has been met. For example, the blending condition may continue until an évaluation shows that the reference standard has been met. In some embodiments wherein the reference standard is composition uniformity, e.g., blend uniformity, evaluating whether a reference standard has been met comprises using near infrared spectroscopy (NIR). In an embodiment, the blending condition is maintained until the NIR spectrum observed shows that a standard for composition uniformity, e.g., blend uniformity, has been met.

Ségrégation of different species of particles in a combination (e.g., dry blended préparation, e.g., PGDBP) during blending or mixing, division of portions, or downstream processing is a barrier to meeting and maintaining reference standards, e.g., a standard of composition uniformity. Any mixture of two or more types of particles can be vulnérable to ségrégation. Ségrégation can occur by one or more of several mechanisms, including sifting, fluidization, and dusting (e.g., see Purutyan, H, and Carson, J.W. Predicting, diagnosing, and solving mixture ségrégation problems. Jenike & Johnson, CSC Publishing, Powder and Bulk Engineering, 2013).

Accessing a sampling point may comprise using a diagnostic technique on the dry blended préparation of the sampling point. In some embodiments, accessing, e.g., using a diagnostic technique, comprises stopping or pausing the blending or mixing or blending condition to access the sampling point. In some embodiments, accessing, e.g., using a diagnostic technique, does not comprise stopping or pausing the blending or mixing or blending condition to access the sampling point. Sampling points may be designated and/or accessed by methods known in the art.
In some embodiments, samples acquired from a sampling point of a combination or dry blended préparation (e.g., PGDBP) or portions of a dry blended préparation (e.g., PGDBP) may be analyzed using near-infrared (NIR) spectroscopy to acquire a value (e.g., for composition uniformity, e.g., blend uniformity). NIR spectroscopy analyzes the absorption spectra of compounds in the NIR wavelength région (780-2500 nm). Absorption peaks of compounds, e.g., pharmaceutical grade amino acid entities, are produced by molecular vibrations classified into two types: overtones and combinations. Compounds comprising CH, OH, or NH bonds can be analyzed using NIR. Methods of interpreting NIR spectra are known in the art. In some embodiments, NIR spectroscopy is used to détermine whether the amounts of amino acid entities at a plurality of sampling points are similar, e.g., whether a standard for homogeneity (e.g., composition uniformity, e.g., blend uniformity) has been met. In some embodiments, the methods further comprise, responsive to the détermination, selecting and/or executing a step, e.g., selecting and using a blending or mixing technique or blending condition or ending blending, mixing, or a blending condition.
In some embodiments, samples acquired from a sampling point of a combination or dry blended préparation (e.g., PGDBP) or portions of a dry blended préparation (e.g., PGDBP) may be analyzed using high performance liquid chromatography (HPLC, also referred to as high-pressure liquid chromatography) to acquire a value (e.g., for the amount of a pharmaceutical grade amino acid entity).
In some embodiments, samples acquired from a sampling point of a combination or dry blended préparation (e.g., PGDBP) or portions of a dry blended préparation (e.g., PGDBP) may be analyzed using liquid chromatography mass spectrometry (LC-MS). In some embodiments, LC-MS is used to détermine the identity and/or amounts of pharmaceutical grade amino acid entities présent at a sampling point or in a portion. In some embodiments, LC-MS is used to déterminé whether a dry blended préparation meets a standard for composition uniformity, e.g., portion or blend uniformity. In some embodiments, the methods further comprise, responsive to the amount(s) of pharmaceutical grade amino acid entities présent, selecting and/or executing a step, e.g., selecting and using a blending or mixing technique or blending condition or ending blending, mixing, or a blending condition.
Reference Standards
The methods described herein produce dry blended préparations, e.g., PGDBPs, which meet one or more reference standards. A reference standard, as used herein, means: a standard used or set by:
(1) a manufacturer of a combination (e.g., dry blended préparation, e.g., PGDBP), e.g., a manufacturer having approval from a govemmental agency to market the PGDBP, or (2) the pharmaceutical industry or agencies or entities (e.g., govemment or trade agencies or entities) regulating the pharmaceutical industry, to ensure one or more product quality parameters are within acceptable ranges for a medicine, pharmaceutical composition, treatment, or other therapeutic. A product quality parameter can be any parameter regulated by the manufacturer, pharmaceutical industry or by agencies or entities, e.g., govemment or trade agencies or entities, including but not limited to composition; composition uniformity; dosage; dosage uniformity; presence, absence, and/or level of contaminants or impurities; and level of sterility (e.g., the presence, absence and/or level of microbes). Exemplary govemment regulatory agencies include: Fédéral Drug Administration (FDA), European Medicines Agency (EMA), SwissMedic, China Food and Drug Administration (CFDA), or Japanese Pharmaceuticals and Medical Devices Agency (PMDA), Health Canada, and Medicines and Healthcare Products Regulatory Agency (MHRA). A product quality parameter can also be a parameter specified by a national or régional pharmacopeia or formulary, including the U.S. Pharmacopeia (USP), British Pharmacopeia (BP), National Formulary (NF), European Pharmacopeia (EP), Japanese Pharmacopeia (JP), or the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH).
The one or more reference standards may be a standard used or promulgated by the pharmaceutical industry or by agencies or entities, e.g., govemment or trade agencies or entities, regulating the pharmaceutical industry to ensure one or more product quality parameters are within acceptable ranges for a medicine, pharmaceutical composition, treatment, or other therapeutic. The one or more reference standards may be a standard used or set by a manufacturer of a combination (e.g., dry blended préparation, e.g., PGDBP), e.g., a manufacturer having approval from a govemmental agency to market the PGDBP, to ensure one or more product quality parameters are within acceptable ranges for a supplément, nutriceutical, medicine, pharmaceutical composition, treatment, or other therapeutic. A product quality parameter can be any parameter regulated by the manufacturer, or by the pharmaceutical industry or by agencies or entities, e.g., govemment or trade agencies or entities, including but not limited to composition; composition uniformity; dosage; dosage uniformity; presence, absence, and/or level of contaminants or impurities; level of sterility (e.g., the presence, absence and/or level of microbes), color, or particle morphology (e.g., size or shape).
Composition Uniformity
In some embodiments, the reference standard is composition uniformity. Composition uniformity, in general, is a standard of homogeneity. Composition uniformity can be classified into two different but related types of uniformity: blend uniformity and portion uniformity (portion uniformity is used interchangeably with content uniformity and dosage uniformity herein). Composition unifonnity may comprise one or both types depending on the usage and context. Composition uniformity may comprise a standard of the homogeneity of a combination (e.g., dry blended préparation, e.g., PGDBP) with regards to one or a plurality of components. In some embodiments, a combination that meets a standard for composition uniformity does so with regards to one, two, three, four, or more (e.g., ail) components (e.g., pharmaceutical grade amino acid entities).
Blend Uniformity
Blend uniformity refers to the level of homogeneity of the distribution of components in a combination, e.g., dry blended préparation, e.g., PGDBP. In some embodiments, a standard for composition uniformity, e.g., blend uniformity, is met when the amount of a component (e.g., a pharmaceutical grade amino acid entity) at a first sampling point in the combination (e.g., dry blended préparation, e.g., PGDBP) differs by no more than a predetermined amount from a reference value. Amounts may be absolute, e.g., grams, or relative, e.g., weight/weight (e.g., X g of the component in Y g of sampling point). Amounts may be arbitrary values, as in the case of comparing absorbance values to absorbance values or in statistical comparisons of curves, e.g., of spectra. In some embodiments, acquiring a value for blend uniformity comprises assessing a standard for composition uniformity, e.g., blend uniformity, by acquiring a value for the amount of a component at a first sampling point in the combination and comparing it to reference value.
In some embodiments, NIR is used to détermine whether the amount of a component (e.g., a pharmaceutical grade amino acid entity) at a first sampling point in the combination (e.g., dry blended préparation, e.g., PGDBP) differs by no more than a predetermined amount from a second or further sampling. Using NIR, the near infrared spectrum for a sampling point can be acquired and compared to the near infrared spectrum for a second or further sampling point (e.g., a third, fourth, fifth, sixth, seventh, eighth, ninth, and/or tenth sampling point) or to the near infrared spectrum for a sample known to meet a reference standard, e.g., a standard for composition uniformity, e.g., blend uniformity. If the comparison shows that the spectra are similar enough to one another, a standard for blend uniformity is met. Similarity of NIR spectra can be evaluated by comparing the conformity index of sampling points. The conformity index is a value generated by the NIR spectra obtained, and the examples of conformity indices described are not an exhaustive list of ali possible conformity indices. The conformity index may be the absorbance at a particular wavelength or wavelengths in the near infrared range. The conformity index may be the standard déviation of the average absorbance at a particular wavelength or wavelengths in the near infrared range at a plurality of sampling points. The key characteristic of the conformity index, whichever value is selected, is that the conformity indices of the sampling points accessed converge (in the case of absorbance at particular wavelength) or reduce (in the case of standard déviation) as blending/mixing time increases. For example, the conformity index may be selected to be a wavelength of X nm in the near infrared range. The absorbance at X nm will be measured at a plurality of sampling points at time points during blending. As blending continues, the absorbance at X nm at each sampling point will grow more similar to one another.
In some embodiments, the reference value is the amount of the component at a second or further sampling point (e.g., a third, fourth, fifth, sixth, seventh, eighth, ninth, and/or tenth sampling point) sampling point in the combination (e.g., dry blended préparation, e.g., PGDBP). The second sampling or further sampling point (e.g., a third, fourth, fifth, sixth, seventh, eighth, ninth, and/or tenth sampling point) point may be a different spatial location in the combination, for example, samples can be collected from a set of predetermined, spread out spatial locations, e.g., a stratified sampling plan with predetermined sites to be sampled, e.g., to obtain samples that represent a variety of locations in the blender or mixer.
In some embodiments, the second sampling point is 1,2, 3, 4, 5, 6, 7, 8, 9, 10, or more minutes after the first sampling point. In some embodiments, multiple sampling points separated in time are taken throughout the process of manufacturing the dry blended préparation (e.g., PGDBP).
In some embodiments, the sampling points separated in time are at intervals throughout the process of manufacturing the dry blended préparation (e.g., PGDBP), e.g., every 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 minutes. In some embodiments, the multiple sampling points are compared to one another (e.g., the most recent sampling points are compared to each other).
In some embodiments, a standard for composition uniformity, e.g., blend uniformity, is met when the amount of the component at a first sampling point differs from the reference value, e.g., the amount of the component at a second or further sampling point (e.g., a third, fourth, fifth, sixth, seventh, eighth, ninth, and/or tenth sampling point) by less than or equal to 1,2, 3, 4, 5, 6, 7, 8, 9, or 10%, e.g., 10%. In some embodiments, a standard for composition uniformity is met when the amount of a component at a first sampling differs by no more than 10% from the amount of the component at a second or further sampling point (e.g., a third, fourth, fifth, sixth, seventh, eighth, ninth, and/or tenth sampling point). In some embodiments, a standard for composition uniformity is met when the amount of a component at a first sampling differs by no more than 10% from the amount of the component présent in the combination (e.g., dry blended préparation, e.g., PGDBP). In some embodiments, a standard for composition uniformity is met when the amount of a component at the most recent sampling point differs by no more than 10% from the amount of the component présent at the next most recent sampling point. Values for the amount of a component présent at a sampling point can comprise NIR spectra. Comparisons of values for the amount of a component présent at a first, second, or further sampling point can comprise comparison of NIR spectra, e.g., overlaying NIR spectra or comparing conformity indices of the first, second, or further sampling points. Blend uniformity can be met when NIR spectra, e.g., conformity indices, reach a threshold of similarity or overlap.
Portion Uniformity
Portion uniformity refers to the homogeneity of portions of the dry blended préparation, e.g., PGDBP, with respect to amounts of components (e.g., pharmaceutical grade amino acid entities). In some embodiments, the methods described herein comprise division of a dry blended préparation (e.g., PGDBP) into a plurality of portions. In some embodiments, a standard for composition uniformity, e.g., portion uniformity, is met when the amount of a component (e.g., a pharmaceutical grade amino acid entity) in a first portion differs by no more than a predetermined amount from a reference value. Amounts may be absolute, e.g., grams, or relative, e.g., weight/weight (e.g., X g of the component in Y g of sampling point). In some embodiments, the amount of a a component (e.g., a pharmaceutical grade amino acid entity) in a first, second, or further portion (e.g., a third, fourth, fifth, sixth, seventh, eighth, ninth, or tenth portion) is determined using HPLC.
In some embodiments, the reference value is the amount of the component in a second portion. In some embodiments, the reference value is the amount(s) of the component in a plurality of portions, e.g., a plurality of test portions (e.g., the first portion is compared to a plurality of test portions). In an embodiment, the reference value is the average or médian amount of the component in the plurality of test portions.
In some embodiments, a standard for composition uniformity, e.g., portion uniformity, is met when the amounts of a component (e.g., a pharmaceutical grade amino acid entity) in a plurality of test portions differ by no more than a predetermined amount from a reference value. Amounts may be absolute, e.g., grams, or relative, e.g., weight/weight (e.g., X g of the component in Y g of sampling point). In some embodiments, the reference value is the average or médian amount of the component in the plurality of test portions.
In some embodiments, the reference value is the amount of the component in the combination (e.g., dry blended préparation, e.g., PGDBP). For example, the reference value can be overall weight/weight of the component présent in the total combination. In some embodiments, evaluating whether a standard for composition uniformity is met comprises comparing a relative amount of a component at a first sampling point (e.g., X g of the component in Y g of sampling point) to the relative amount of the component in the combination (e.g., W g of the component in Z g of combination total); in other words, evaluating the standard for composition uniformity may comprise comparing X/Y to W/Z.
In an embodiment, at least X% of the portions of the plurality of portions of the dry blended préparation (e.g., PGDBP) are test portions, wherein X is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, or 50. In some embodiments, no more than X% of the portions of the plurality of portions of the dry blended préparation (e.g., PGDBP) are test portions, wherein X is 50, 45, 40, 35, 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1. In an embodiment, test portions are portions compared to a reference value, e.g., one another or the amount of a component présent in the dry blended préparation (e.g., PGDBP), to détermine whether a reference standard (e.g., for composition uniformity, e.g., portion uniformity) has been met. In some embodiments, a standard for composition uniformity, e.g., portion uniformity, is met when the amount of a component présent in at least X% of test portions differs from a reference value by no more than 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10%, wherein X is 50, 60, 70, 80, 85, 90, 95, 99, or 100%, and wherein the reference value is selected from the average amount of the component présent in the test portions, the médian amount of the component présent in the test portions, or the amount of the component présent in the dry blended préparation (e.g., PGDBP).
In some embodiments, portions of the dry blended préparation (e.g., PGDBP) may be stick packs or other unit dosage forms.
Level of Contamination
In some embodiments, the reference standard is level of contamination. When combining raw materials, e.g., pharmaceutical grade amino acid entities and/or excipients, into a combination, e.g., dry blended préparation, e.g., PGDBP, contaminants may be présent in the combination. A combination, e.g., dry blended préparation, e.g., PGDBP, meets a standard for level of contamination when the combination does not substantially comprise (e.g., comprises less than 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.15, 0.1, 0.05, 0.01, or 0.001% (w/w) of) a contaminant. In some embodiments, a combination, e.g., dry blended préparation, e.g., PGDBP, comprises less than 0.15% (w/w) of a contaminant. In some embodiments, a combination, e.g., dry blended préparation, e.g., PGDBP, comprises a lower level of a contaminant than the level permissible in food (e.g., as defined by appropriate regulatory organizations known in the art). In some embodiments, a combination, e.g., dry blended préparation, e.g., PGDBP, described in a method herein does not comprise a contaminant. Contaminants include any substance that is not deliberately présent in the combination, e.g., dry blended préparation, e.g., PGDBP, (for example, pharmaceutical grade amino acid entities and excipients, e.g., oral administration components, are deliberately présent) or any substance that has an unintended négative effect on a product quality parameter of the PGDBP or plurality of portions of PGDBP (e.g., side effects in a subject, decreased potency, decreased stability/shelf life, discoloration, odor, bad taste, bad texture/mouthfeel, or increased ségrégation of components of the PGDBP). In some embodiments, contaminants include microbes, endotoxins, metals (e.g., heavy metals), residual solvents, raw material impurities, extractables, and/or leachables.

EXAMPLES
The Examples below are set forth to aid in the understanding of the inventions, but are not intended to, and should not be construed to, limit its scope in any way.
Introduction
The compositions comprising amino acid entities were tested in normal and disease-specific human primary cell models. The model Systems were conducted in environments that aim to simulate physiological levels of biofluids and nutrients. These models include disease conditions (e.g., inflammation) to isolate and better understand the effects of the compositions on subsets of metabolic pathways. The high throughput nature of these models enabled the discovery of spécifie combinations of amino acid entities that may hâve bénéficiai, multi-pathway effects in subj ects with a hemoglobinopathy (e.g., sickle cell disease) or a thalassemia (e.g. α-thalassemia or β-thalassemia).
Example 1. Cytokine Sécrétion in Primary Human Macrophages. Isolation of Peripheral Blood Mononuclear Cell (PBMC)
Unpurified buffy coats (Research Blood Components) were carefully poured into 50mL centrifuge tubes and diluted with room température Dulbecco’s Phosphate Buffered Saline (dPBS) with Calcium and Magnésium (Gibco). Diluted buffy coats were further divided into four total 50mL centrifuge tubes at 20mL per tube. Lymphocyte Séparation Medium (Corning) was carefully pipetted to the bottom of each centrifuge tube. Mixtures were centrifuged at 850 X g for 32 minutes at 20°C with 0 décélération and accélération.
The PBMC layer was separated from other components after centrifugation and added to new 50mL centrifuge tube containing 25mL dPBS. Total volume was brought up to 50mL with dPBS and centrifuged at 600 X g for 10 minutes at 20°C with accélération of 9, décélération of 5. Supematant was carefully removed from cell pellets. The cell pellets were resuspended using lOmL dPBS. Total volume was then brought up to 50mL using dPBS and centrifuged at 450 X g for 5 min at 20°C with accélération of 9, décélération of 9. The supematant removal and cell pellet resuspension was repeated again.
The supematant was then carefully removed from cell pellets. Cell pellets were resuspended in lOmL dPBS without calcium or magnésium and filtered through a 70 uM cell strainer. The total PBMC number was determined using a Cellometer K2 automated cell counter. A total of 5E6 cells were saved for flow cytométrie analysis. Remaining cells were centrifuged at 490 X g for 5 minutes at 20°C with accélération of 9, décélération of 9.
CD 14+ Cell Sélection
CD 14+ cells were selected using EasySep™ Human CD 14 Positive Sélection Kit II (STEMCELL Technologies). Cells were resuspended in cold EasySep™ Buffer (STEMCELL Technologies) at 1X108 cells/mL. A total of 100 uL/mL EasySep™ Human CD14 Positive Sélection Cocktail II was added to the cell suspension, mixed, and incubated at room température for 10 minutes. A total of 100 uL/mL RapidSpheres were added to the mixture and incubated at room température for 3 minutes after mixing, then RoboSep buffer was added to bring up the total volume to 10mL. The mixture in a 15 mL tube was placed in magnet and incubated at room température for 3 minutes. Supematant was discarded and 10 mL fresh EasySep™ buffer was added to 15mL tube. The addition of RoboSep buffer, mixing, and discarding of supematant was was repeated two more times.

Resuspended cells were seeded back onto 10cm tissue culture plates and incubated at 37°C, 5%CO2. Differentiated macrophages were used for subséquent experiments.
Screen
Primary human PMBC derived macrophages were seeded on day 0 at 3.0E4 cells per well in 96-well microplates (ThermoFisher) in Dulbecco’s Modifïed Eagle Medium (DMEM) (Gibco) supplemented with penicillin-streptomycin (Hyclone) and 10% heat inactivated fêtai bovine sérum (HI-FBS) (Atlanta Bio) and incubated ovemight at 37°C, 5% CO2.

On day 2, cells were treated with 75uL of the same médiums described above supplemented with 0.30ng/mL lipopolysaccharide (LPS) (Sigma) for a final concentration of 0.15ng/mL LPS. Control wells were treated with luM BX-795 (Tocis), luM TAK242 (Sigma), 0.15ng/mL LPS, or phosphate buffered saline (PBS).
On day 3, the supematant was collected and immediately frozen in -80°C freezer. Cells were washed once with 150uL DPBS and viability was assessed using the WST-8 Cell Prolifération Cytotoxicity Assay (Dojindo). Following the assay, cells were washed twice with 150uL PBS and fixed with 4% paraformaldéhyde for 5 min followed by two additional washes with 150uL PBS. Protein levels in supematant samples were analyzed by ELISA for IL-6 and TNFa using commercially available kits (R&D Systems) according to manufacturer-supplied protocols. Results are shown in Tables -7-12 below.

Treatment with LIVRQNAC, LIVRQNAC + G, LIVRQNAC + S, RQNAC, and NAC signifïcantly reduced LPS-induced TNFa sécrétion in primary human monocyte-derived macrophages. Treatment with LIV and LIVRQ increased TNFa sécrétion. Individually administered amino acids had no significant effect on TNFa sécrétion, except for glutamine which increased TNFa sécrétion. Two Way ANOVA Dunnett Multiple Comparisons was performed for statistical analysis. Mean values represented as baseline subtracted values.
An imbalance of pro-inflammatory and anti-inflammatory cytokine production has been proposed to correlate with the development of vasoocclusive crises (VOC) and their severity in sickle cell disease (Sarray et al. 2015; hereby incorporated by reference in its entirety). VOC are a hallmark complication of sickle cell disease resulting in ischémie injuries and severe pain. Sarray et al. (2015) demonstrated that élévations of the pro-inflammatory cytokine IL-6 correlated with duration of VOC, together with enrichment of enrichment of high IL-6 and TNFa quartiles in the VOC group, and that reduced pro-inflammatory IL-10 correlated with VOC frequency, type, severity, and duration. Together their results highlight the importance of pro- and anti-inflammatory balance in sickle cell disease pathology.
Example 2. Reactive Oxygen Species in Sickle Cell Disease Patients.
Deoxygenation of hemoglobin results in superoxide production, which is amplified when oxygen withdrawal increases such as occurs during hypoxia, reduced blood flow or anémia (Rogers et al. 2009). As such, érythrocytes require robust antioxidant defense Systems and serve as a sink for systemic reactive oxygen species (ROS, Rogers et al. 2009). ROS are reported to be generated at a higher rate in whole blood and érythrocytes in sickle cell disease patients than in healthy Controls and both the abundance of reduced glutathione (GSH) as well as the ability to recycle GSH are impaired, resulting in membrane protein oxidation, membrane fragility, and vascular dysfunction (Amer et al. 2003, 2004, 2005, Rogers et al. 2013).
Hydrogen Peroxide (H2O2) was used to induce ROS in samples of whole blood from healthy Controls (Research Blood Components) and from sickle cell disease patients (IRB approval, Boston Children’s Hospital) following a protocol adapted from Amer et al. 2004. Whole blood samples were appropriately diluted in Ca2+- and Mg2+-free Dulbecco’s phosphate buffered saline (DPBS, Life Technologies) and the concentration of érythrocytes (RBC/ml) was measured on a Cellometer K2 Fluorescent Viability Cell Counter according to the manufacturer’s RBC/AOPI protocol (Nexcelom Biosciences).
Cells were then diluted to l*106 RBC/ml into either prewarmed 37°C DPBS or HEPESbuffered physiological solution (HPS) as adapted from Wesseling et al. (2016) containing (mM): 145 NaCl, 7.5 KC1, 10 Glucose, 10 HEPES, 2 CaC12, pH 7.4, 0.2 μ filtered, and supplemented with the 20 proteogenic amino acids at Ix the basal concentrations présent in the HMDB (Wishart DS, Tzur D, Knox C, et al., HMDB: the Human Metabolome Database. Nucleic Acids Res. 2007 Jan;35(Database issue):D521-6. 17202168)) (Millipore Sigma). 2’-7’-dichlorofluorescin diacetate (DCF, Millipore Sigma), 20 mM in dimethyl sulfoxide (DMSO, Fisher) were added to a working concentration of 100 μΜ. Cells were incubated with dye for 15 minutes at 37°C, 5% CO2 in a tissue culture incubator, washed once, and resuspended in the 0.9 volumes of the same prewarmed 37°C buffer with 5 minute spins at 500 xg, accel/decal=5 in a swing arm centrifuge (Beckman Coulter). Cells were distributed into 96 well clear bottom black microplates, 90 μΐ/well (Corning) and then 10 μΐ of the same buffer was added per well optionally containing individual or combinations of amino acids designed to increase their concentration by Ix, 5x, lOx, or 20x basal concentrations présent in the HMDB (Human Metabolome Database (Wishart DS, Tzur D, Knox C, et al., HMDB: the Human Metabolome Database. Nucleic Acids Res. 2007 Jan;35(Database issue):D521-6. 17202168)) or non-proteogenic amino acids to a final concentration of 0.1, 1,2, or 5 mM. Where possible due to solubility constrains, pH-7.4-adjusted stock solutions of amino acids were used. Wells were mixed by pipetting and plates incubated at 37°C, 5% CO2 in a tissue culture incubator for 30 minutes. Optionally, 40 mM H2O2 (Millipore Sigma) freshly prepared in the same buffer was added to bring the concentration to 2 mM, wells mixed by pipetting, and plates were incubated an additional 30, 60, 120, or 240 minutes before fluorescence measurement of ROS signal on a Synergy H4 (BioTek) microplate reader with excitation=488 nm and emission=530 nm, and gain either set to autogain, 75, or 100.
N-acetylcysteine (Spectrum) and cysteine reduced ROS measured in whole blood of healthy control donors treated with H2O2 in a dose-responsive fashion and in samples of sickle cell disease patient blood both treated with H2O2 and untreated in DPBS. Additionally, lOx tryptophan increased ROS signal in both healthy donor blood and sickle cell disease patient blood, providing evidence for its exclusion from the composition. Ail other amino acids tested did not affect ROS measurement either alone or in combination with NAC or cysteine, showing that their inclusion in the composition were not detrimental for combating pathological oxidative stress in sickle cell disease.
Example 3. Amino Acid Profiling of Erythrocytes.
Concentration différences in plasma and érythrocyte amino acids in sickle cell disease hâve been described and are thought to contribute to endothélial dysfunction. For example, release of érythrocyte arginase through hemolysis has been described to contribute to lower plasma arginine, contribute to limited bioavailability of this amino acid and a pathological State of nitric oxide (NO) résistance (Morris et al. 2005). Metabolomics studies hâve also identified amino acid level and pathway dysrégulation, hypothesized to contribute to disease pathology (Darghouth et al. 2011).
Plasma and érythrocyte amino acids, as well as oxidized and reduced glutathione, will be analyzed in sickle cell disease patient whole blood samples (IRB approval, Boston Children’s Hospital) as well as in whole blood from race-matched healthy Controls. While it is not possible to control for fed or fasted State at the time when samples are taken, statistical différences between érythrocyte and plasma amino acid concentrations in patients and healthy Controls are thought to represent robust différences in metabolism in the disease State and may contribute to disease pathology. Amino acid for which différences are observed between healthy Controls and sickle cell disease patients at either trend level or statistical significance will be prioritized for screening in other assays such as résistance to sickling under hypoxia and exposure of adhesion markers such as phosphatidylserine.
Example 4. Adhesion Biomarkers.
The hallmark of sickle cell disease is the “sickle cell crisis,” caused by vaso-occlusion of small blood vessels that lead to ischémie injuries and severe pain. A number of factors conspire toward vaso-occlusion: increased rigidity and adhesion of sickle RBCs make them more likely to stick to circulating WBCs and the vascular endothélium; increased arginase from hemolysis depletes free plasma arginine necessary to generate nitric oxide (NO), impairing vasodilation. Sickle cell crises are the primary reason that patients seek medical care, and can be life threatening as they can occur in any organ and last for several days. Crises in the pulmonary vasculature manifest as acute chest syndrome;” those in the brain can cause stroke or “silent” cérébral infarcts; those in bone can lead to osteonecrosis; and crises elsewhere can lead to damage and failure in nearly any organ. Sickling leads to physical disruption and increased turnover of the érythrocyte membrane, increased cell rigidity, cell déhydration through loss of potassium, and increased RBC adhesion via extemalization of phosphatidylserine. Red blood cell adhesion to leukocytes and to vascular endothélial cells, mediated by increased phosphatidylserine exposure, is among the mechanisms of vaso-occlusion in sickle cell disease, and measurement of phosphatidylserine exposure correlates well with other assays of adhesion such as érythrocyte adhesion to human umbilical vein épithélial cells.
Phosphatidyl serine exposure will be measured by binding of Annexin V conjugated to the fluorescent probe Alexa 488 (Life Technologies), either in untreated sickle cell disease patient blood (IRB approval, Boston Children’s Hospital), healthy control donor blood (Research Blood Components) under untreated conditions or when treated with a disease-pathology-relevant stimulus known to provoke phosphatidylserine exposure such as hypoxia or the calcium ionophore 4-br A23187 (Millipore Sigma). The ability of amino acid treatments at multiples of the basal levels found in the HMDB (Human Metabolome Database (Wishart DS, Tzur D, Knox C, et al., HMDB: the Human Metabolome Database. Nucleic Acids Res. 2007 Jan;35(Database issue):D521-6. 17202168)) to modify phosphatidylserine exposure will be observed under these conditions. Individual or combinations of amino acids able to reduce exposure of the adhesion marker phosphatidylserine will be potential therapeutics for réduction of vaso-occlusion.
Example 5. Résistance of Erythrocytes to Sickling.
Under hypoxie conditions, such as in peripheral tissues, or during anémia, sickle cell disease érythrocytes change their morphology to the characteristic “sickle” shape due to polymerization of sickle hemoglobin (HbS). This increases cell rigidity and contributes to vaso-occlusion (Du et al. 2015). Potential treatments that provide résistance to sickling either by decreasing the proportion of cells that sickle under hypoxia, as has been shown for hydroxyurea, or by increasing the time cells take to sickle, could reduce vaso-occlusion pathology.
Single amino acids and combinations at multiples of the basal levels found in the HMDB (Human Metabolome Database (Wishart DS, Tzur D, Knox C, et al., HMDB: the Human Metabolome Database. Nucleic Acids Res. 2007 Jan;35(Database issue):D521-6. 17202168)) will be tested for their ability to provide sickle cell disease patient whole blood samples diluted in appropriate buffer with résistance to sickling under incubation in a hypoxie gas mixture (2% O2, 5% CO2, balance N2, Middlesex Gasses & Technologies). Samples will be imaged in a 96-well black fluorescence microplate with optical bottom (Thermo Fisher) over a time course on an ImageExpress Micro Confocal microscope (Molecular Devices), and the percentage of sickled cells will be identified at each time point. Amino acids or combinations imparting résistance to sickling will be considered for inclusion in the composition against a body of evidence for these amino acids.
Example 6. Calcium Influx of Erythrocytes.
Sickle cell érythrocytes are described as having a persistent calcium leak, exacerbated under hypoxia and sickling, resulting in exposure of adhesion markers such as phosphatidylserine and contributing to disease pathology.
Calcium influx into sickle cells will be measured by pre-loading sickle cell disease patient whole blood with the intracellular calcium probe Fluo-4 AM (Life Technologies) according to the manufacturées instructions. Single amino acids and combinations at multiples of the basal levels found in the HMDB (Human Metabolome DataBase (Wishart DS, Tzur D, Knox C, et al., HMDB: the Human Metabolome Database. Nucleic Acids Res. 2007 Jan;35(Database issue):D521-6. 17202168)) will be tested for their ability to provide sickle cell disease patient whole blood samples diluted in appropriate buffer with résistance to calcium influx under incubation in a hypoxie gas mixture (2% O2, 5% CO2, balance N2, Middlesex Gasses & Technologies). Samples will be imaged in a 96-well black fluorescence microplate with optical bottom (Thermo Fisher) over a time course on an ImageExpress Micro Confocal microscope (Molecular Devices), and calcium influx will be measured by observing fluorescence intensity with excitation=488 nm emission=530 nm of either those érythrocytes with sickle phenotype or ail cells.
Example 7. Berkeley mouse model of sickle cell anémia
Several transgenic mouse models hâve been developed to examine the systems-nature pathology and treatment of sickle cell disease. One such model called the Berkeley mouse (BERK) was developed to exclusively express human hemoglobin chains, including the sickle hemoglobin variant (HbS), which leads to sickle cell anémia in these mice (Paszty C et al, 1997. Science). The BERK model well approximates many different facets of the disease, including: anémia, reticulocytosis, irreversibly sickled cells, increased red blood cell turnover, and multi-organ pathology (de Jong K et al, 2001. Blood).
Combinations of amino acids at multiples of the basal levels found in the HMDB (Human Metabolome Database (Wishart DS, Tzur D, Knox C, et al., HMDB: the Human Metabolome Database. Nucleic Acids Res. 2007 Jan;35(Database issue):D521-6. 17202168)) will be tested against placebo and multiple levels of L-glutamine for their systems-therapeutic effect in the BERK mouse model. Animais will be gavaged BID for 4 weeks in one of six treatment arms: (1) vehicle, (2) low dose L-glutamine, (3) high dose L-glutamine, (4) low dose composition consisting of L R Q NAC G Car H K V, (5) high dose dose composition consisting of L R Q NAC G Car H K V, or (6) high dose dose composition consisting of L R Q NAC. Weekly blood draws from tail vein puncture will be analyzed for hematological parameters (complété blood count), including but not limited to 82 hematocrit, hemoglobin, érythrocyte volume, réticulocyte count, WBC count, and platelet count. Blood draws will be also analyzed for plasma and RBC amino acid profiles, cytokine panels, ROS, PS exposure, and other relevant cell or molecular markers. Biotinylation of red blood cells prior to blood draws and analysis by flow cytometry will allow for quantification of red blood cell turnover. Histopathology will allow for comparison of organ damage in control and treatment groups.
Combinations of amino acids that improve hematological parameters, érythrocyte health and turnover, and limit organ damage will provide support for therapy in sickle cell anémia.
Example 8. RBC deformability studies in an ex vivo induced model of hemolysis with amino acids pre-treatment
Whole blood from healthy African American and/or Hispanic donors was obtained from Research Blood Components, LLC based on the following donor sélection criteria: Adult âge (between 18 and 50 years), normal BMI (<30), and absence of other confounding clinical conditions. Whole blood from SCD donors were obtained from BioIVT based on the following donor sélection criteria: Patients with génotypes HbSS, HbSC, HbS/β0 and ai least 1-2 months gap since last blood transfusion. Whole blood was shipped on ice on the same day as blood draw. Upon receipt, the blood sample was aliquoted and stored in the refrigerator until used for studies.
RBC deformability measurements were conducted with the Laser Optical Rotational Red Cell Analyzer (LORRCA) from RR Mechatronics in a temperature-controlled environment (37°C). Briefly, an even layer of RBCs suspended in polyvinylpyrrolidone (PVP) is subjected to shear stress gradient (0.3 to 30 Pa) through two concentric cylinders and the resulting changes in RBC shape or deformability are measured by a laser beam diffraction pattern. The captured images of RBC shape in response to increasing shear stress are then analyzed by the LORRCA program to calculate Elongation Index (El).
Healthy RBCs hâve higher deformability >0.5 El and SCD RBCs hâve lower deformability or El values as studied by LORRCA ektacytometry in the field. It has been suggested in prior literature that changes at Ά EImax shear stress <1.69 Pa indicate change in RBC membrane flexibility and at shear stress >3.0 Pa indicate impact on RBC cell surface/volume ratio, intracellular viscosity along with membrane flexibility (Renoux C, et al, Sci Rep. 2019 May 1 ;9(1):6771). The induced hemolysis model in this disclosure involves use of tert-butyl hydroperoxide (TBHP) to lower El of RBCs. TBHP has been shown to permeabilize membrane, oxidize cells, induce proteolysis, inhibit enzyme activities and induce hemolysis, thus simulating the pathology of SCD (Roy A, et al,
Pathophysiology. 2012 Apr;19(2): 137-48 and Runge-Morris M, et al, Chem Res Toxicol. 1989 MarApr;2(2):76-83).
The ex vivo hemolysis study disclosed here involves ovemight treatment of whole blood with vehicle as a control and spécifie amino acids followed by rapid oxidation (5 min) with TBHP. Method for oxidation of whole blood with tert-butyl hydroperoxide has been used in prior literature (Diederich L, et al, Front Physiol. 2018 May 11;9:332). RBC deformability or shape changes are then measured with LORRCA ektacytometry.
Whole blood aliquots stored in the fridge were brought up to room température while gently shaking on a rocker at low speed for an hour to ensure graduai and uniform suspension of red blood cells prior to deformability measurements. Vehicle control used in the study was IX Dulbecco’s Phosphate vehicle) and amino acids disclosed herein were added (at either final 10X or 2.5 mM concentration as indicated) to corresponding vehicle and amino acid treatment conditions. The samples were then incubated ovemight at 37°C. Next day, 25 pL of whole blood was taken from each treatment condition and added to 5 mL Elon ISO viscous solution from RR Mechatronics. The sample was inverted 15-20 times to ensure proper mixing of the treated RBCs with the Elon ISO solution followed by loading the sample on LORRCA and capturing RBC deformability or shape measurements over the applied shear gradient. The remaining whole blood treatments were retumed to incubator (37°C) until deformability measurements were completed for ail treatments. To the remaining whole blood treatment samples, TBHP solution (5.0-6.0 M in Decane, Sigma) was added at 2.5 mM final concentration from a 100 mM freshly prepared stock and incubated for further 5 min at 37°C. 25 pL of this TBHP-treated sample was immediately removed at the end of the 5 min incubation and added to the Elon ISO solution for RBC deformability measurement after oxidation. Included in the Tables 13-15 are El measurements at Ά EImax shear stress 1.69 Pa and EImax shear stress 30 Pa from these studies and Fig. 1 captures El measurements for ail shear stress points for the indicated treatment conditions.
Results
RBC deformability or élongation index (El) measurement in the ex vivo hemolysis model
Fig. 1 shows changes in healthy RBC deformability from healthy donor 1 with and without TBHP oxidation of whole blood for the indicated pre-treatments with spécifie amino acids disclosed herein or DPBS vehicle. The RBC deformability measurements are shown on Y-axis in terms of El and the applied shear stress (Pa) is shown on X-axis. The El measurement for each shear stress is a mean of 50 measurements. Solid lines represent ovemight pre-treatments of whole blood without TBHP oxidation and dot-dashed lines represent after TBHP oxidation.
Table 13 captures RBC deformability measurements (El) at half max shear stress (1.69 Pa) and max shear stress (30 Pa) from Fig. 1. Two different fold changes are shown in Table 13. El Fold Change with Tert-butyl Hydroperoxide shows différence in El with and without TBHP oxidation for each pre-treatment group. RBC deformability of vehicle control at U EImax shear stress (1.69 Pa) is reduced by 4.7-fold when treated with TBHP and at EImax (30 Pa) is reduced by 2.0-fold. Fold change in RNacCitQCar pre-treatment group had respectively 2.9-fold and 1.5-fold decreases in RBC El with TBHP oxidation for both shear stress points. RNacCitQCarLHKVS pre-treatment group had lowest fold change with TBHP oxidation of 1.8-fold and 1.2-fold for the two shear stress points. El Fold Change Relative to Vehicle shows différence in El relative to vehicle control group. RNacCitQCarLHKVS pre-treatment group has the highest improvement in Yi EImax and EImax over vehicle group for TBHP oxidation by 2.6- and 1.9-folds respectively followed by RNacCitQCar group. Results from Fig. 1 and Table 13 suggest lower El with TBHP oxidation for ail pre-treatment conditions with lowest El for vehicle, higher El for RNacCitQCar and highest El for RNacCitQCarLHKVS suggesting benefit of these amino acid compositions in minimizing loss of deformability or El upon oxidative and hemolytic damage to RBCs.
Results from Table 14 show deformability for single amino acid treatments upon TBHP oxidation in healthy whole blood from healthy donor 2. The El for R, Cit, Nac, Q, Car single amino acid treatments over vehicle control is higher than the vehicle for both % EImax and EImax measurements. Q treatment group was least effective and RNacCitQCarLHKVS was most effective among ail treatment groups as shown by both, individual El measurements for U EImax, EImax and the fold change or El improvement relative to vehicle control. Additionally, both healthy donors 1 and 2 show highest El with TBHP oxidation for RNacCitQCarLHKVS pre-treatment groups based on Tables 13 and 14. Results from Table 16 additionally show effect of RNacCit in whole blood from healthy donor 2. El of RBCs pre-treated with RNacCit shows 1.8-fold better deformability than vehicle at Ά EImax shear stress and about 1.5-fold better at EImax in response to TBHP oxidation.
Results from Table 15 show linear increase in deformability or El in RBCs from an SCD donor when pre-treated ex vivo with increasing doses of amino acids RNacCitQCarLHKVS followed by rapid TBHP oxidation. Fold change in RBC deformability or El shows dose response for 5X, 10X and 20X RNacCitQCarLHKVS pre-treatments relative to vehicle control with highest 5.3-fold change observed for 20X pre-treatment.
Combinée! results from Tables 13-15 and Fig. 1 demonstrate benefit of spécifie amino acid compositions disclosed herein in reducing loss of RBC deformability or shape as measured by El in response to damage from oxidation, proteolysis and hemolysis. Réduction in hemolysis could potentially minimize vaso-occlusive pain crises and organ damage in sickle patients.

Example 9. Endothélial Cell Screening
Vascular dysfunction in SCD can manifest in the expression of vascular endothélial cell (VEC) adhesion markers, inflammatory cytokines, and reduced synthesis of nitric oxide (NO) and
NO-dependent endothélial function. This multi-faceted pathology can contribute to decreased blood perfusion and an increased likelihood of acute vaso-occlusive events or progressive organ damage.
A VEC model was employed to assess the ability of amino acids to influence aspects of vascular dysfunction in SCD. TNFa treatment of healthy donor HLMVEC mimics the SCD disease state and induces expression of adhesion markers ICAM-1 and VCAM-1, and sécrétion of proinflammatory cytokine IL-6. It is established that levels of ICAM-1, VCAM-1, and IL-6 can contribute to SCD pathology and correlate with the incidence and severity of complications in SCD patients. The VEC model sought to test the ability of amino acids to reduce the TNFa-induced disease phenotype by lowering expression of adhesion markers (ICAM-1 and VCAM-1) and inflammatory cytokines (IL-6) while promoting VEC health and viability.
Primary Human Lung Microvascular Endothélial Cells (HLMVEC; Lonza) were seeded at 6,000 cells per well in Endothélial Cell Growth Basal Medium-2 (Lonza) supplemented with Fêtai Bovine Sérum (FBS; Lonza), human EGF (Lonza), human VEGF (Lonza), R3-Insulin-like Growth Factor-1 (Lonza), ascorbic acid (Lonza), hydrocortisone (Lonza), human FGF-beta (Lonza), and gentamicin/amphotericin-b (Lonza) in a 96-well plate (Thermo Fisher). The cells were incubated for 45 minutes at room température, then incubated overnight at 37°C/5%CO2.
Following overnight incubation, cell were washed once with 150 pL of Dulbecco’s phosphate buffered saline (DPBS; Gibco), and then treated with Endothélial Basal Medium MCB131 (amino acid, glucose, sodium pyruvate, and phénol red free; US Biologicals) containing a defined custom amino acid concentration based on physiological concentrations in blood of patients with SCD (thus recapitulating observed metabolic imbalances such as the déplétion of certain essential amino acids including arginine and aspartate and enrichment of certain non-essential amino acids including glutamate and asparagine), dialyzed FBS (Hyclone), human EGF (Lonza), human VEGF (Lonza), R3-Insulin-like Growth Factor-1 (Lonza), ascorbic acid (Lonza), hydrocortisone (Lonza), human FGF-beta (Lonza), and gentamicin/amphotericin-b (Lonza), glucose, 10 mM HEPES, sodium pyruvate, and sodium bicarbonate supplemented with one of the following:
a. PB S (vehicle control),
b. 0.5 ng/mL Tumor Necrosis Factor alpha (TNFa) and PBS, or;
c. 0.5 ng/mL TNFa and amino acid treatments at 20X mean physiological concentrations in plasma based on values published in the Human Metabolome Database (HMDB) in PBS.
After 24 hours of treatment, cells were washed once with 150 pL of DPBS (Gibco), then fixed with 4% paraformaldéhyde. Following fixation, cells were stained with anti-ICAM-1 [MEM111] (mouse IgG2a anti-human; abcam) and anti-VCAMl [1.4C3] (mouse IgGl, κ anti-human; abcam) primary antibodies at 1000X, and 100X dilutions respectively. Cells were then stained with Goat anti-Mouse lgG2a Cross-Adsorbed Secondary Antibody, Alexa Fluor 594 (Invitrogen) and Goat anti-Mouse IgGl Cross-Adsorbed Secondary Antibody, Alexa Fluor 647(Invitrogen) secondary antibodies. Nuclei were stained with Hoechst 3342 (Life Technologies).
Antibody binding was detected by fluorescence microscopy using a high content imager (Molecular Devices). Images were analyzed using MetaXpress 6 software to détermine the integrated intensity per cell for each wavelength corresponding to ICAM-1 or VCAM-1.
Supematants were analyzed for IL-6 concentrations using a Human Cytokines FirePlex-HT
Panel 1 kit (abcam) according to the manufacturer-supplied instructions. Particles were imaged on a high content imager (Molecular Devices), and results were interpolated from a standard curve with FirePlex Analysis Workbench Software (abcam) according manufacturer’s recommendations.

RCitNac greatly reduced TNF-α induced ICAM-1 expression levels in HLMVEC cells. Gly, 10 CitNac and Nac also reduced levels of ICAM-1 expression to a lesser extent. HLMVEC cells treated with RCitNacQCarLHKVS and RCitNacQCar moderately reduced TNF-α induced ICAM-1 expression levels. RCitNac, Nac, Gly, and CitNac greatly reduced VCAM-1 expression in HLMVEC cells. RCitNacQCarLHKVS, had a moderate effect on VCAM-1 expression in these cells, as did Cit, and Car.
Summary of results: As described, an idéal treatment is one that addresses the multifactorial pathology of SCD as represented by HLMVEC by reducing disease phenotypes (VCAM1, ICAM1, IL6). The ability of single amino acids and combinations to simultaneously impact these phenotypes was measured by a META-rank score (Tables 17 and 18). META-rank score is a composite measure that considers the optimal impact on ail 3 phenotypes (e.g. decrease VCAM1, ICAM1, and IL6) in the HLMVEC model. An optimal amino acid or combination treatment (i.e. treatment that has the desired effect on ail measures) has a lower score than a sub-optimal treatment (i.e. treatment has an undesirable effect on ail measures). Based on META-rank the RCitNac was the optimal treatment, and the combinations RCitNacQCar and RCitNacQCarLHKVS were among the optimal treatment conditions.
Example 10. Assessment of the Pharmacokinetics of Multiple Compounds Following Oral Dose Administration to Male Sprague-Dawley Rats
SUMMARY
A pharmacokinetic (PK) analysis was performed on plasma concentrations of various combinations of amino acid compounds administered by oral gavage to male Sprague-Dawley rats. Four animais were dosed with RCitNacQCarLHKVS, a test article comprising ten amino acid components: arginine, citrulline, N-acetylcysteine, glutamine, camitine, leucine, histidine, lysine, valine, and serine (Table 19). Animais were fasted for 2 hours prior to dose administration. Plasma samples were taken immediately pre-dose and 0.5, 1, 2, 3, 4, and 5 hours post-dose.
Bioanalysis of collected plasma samples for amino acid content was performed at Axcella Health using an LC-MS method (Section 2.1). Bioanalytical data were analyzed using noncompartmental analysis with Phoenix® WinNonLin® (v8.1).
Most compounds dosed as part of RCitNacQCarLHKVS rose in concentration after dosing, reaching maximum concentration between 0.5 and 3 hours post-dose, with camitine and Nacetylcysteine the only exceptions. Camitine continuously increased over the course of the five-hour time course, while N-acetylcysteine was not detected in plasma. PK parameters, such as Tmax, Cmax, and AUCo-5h were tabulated.
METHODOLOGY
Summary of Sample Analysis Procedures
An LC/MS method utilizing HILIC chromatography and high-resolution mass spectrometry was used to quantify amino acids in rat plasma. The samples were prepared by protein précipitation and spiked with stable-labeled amino acid internai standard for each analyte. Calibration standards were used for absolute quantification and the linear range for each analyte was generally from 10 to 2000 μΜ. QCs, spiked into rat plasma, were utilized to assess the accuracy of the method.
Pharmacokinetic (PK) Analysis
PK parameters of test article components were determined from individual rat plasma concentration-time data by employing a noncompartmental approach using Phoenix WinNonlin® (Version 8.1) software. Nominal times were used to calculate the toxicokinetic parameters. Plasma pharmacokinetic parameters such as Tmax, Cmax, and AUCo-sh were tabulated, as appropriate. This program analyzed data using the standard methods described by Gibaldi and Perrier (see M. Gibaldi and D. Perrier, Pharmacokinetics, 2nd édition, New York: Marcel-Dekker, Inc.; 1982.).

Example 11. Monitoring Homogeneity in Real Time using NIR - Additional Combinations and V-blender Blending
FIG. 2A shows the time-dependent approach to blend uniformity during the processing of a third additional exemplary combination of amino acid entities (the exemplary combination of Table 3) using a V-blender. Samples for generating NIR spectra were taken every four minutes. The collapse of the NIR spectra at late time points indicates that the combination has achieved blend uniformity. FIG. 2B represents the average of four randomly-selected independent stick packs and amino acid recovery data is expressed as a 90-110 percent of label claim. The data when taken together, indicate blend and content uniformity had been achieved.
These experiments demonstrate that the methods described herein may be used to achieve blend and content uniformity for additional combinations of amino acid entities and that a variety of blending techniques, including V-blender blending, are suitable for achieving uniformity.
Example 12. Treatment of Sickle Cell Disease Patients with an Amino Acid Composition
The study described herein features the administration of a composition including amino acids to treat patients with Sickle Cell Disease (SCD). This study’s aim is to assess the food safety and tolerability of the composition over 12 weeks in subjects with sickle cell disease (SCD).
Safety and tolerability will be assessed by: reported ciinical adverse events; physical examinations, vital sign and ECG; and ciinical laboratory tests including changes in hematology, chemistry, plasma amino acids and other inflammation and vascular adhesion/functional markers. Structural and functional changes will be assessed by: multiparametric magnetic résonance imaging for brain and kidney perfusion; the 6-Minute walk metric; and puise oximetry. Approximately 48 male and female subjects > 12 years old with a prior confirmed diagnosis of SCD will be assessed.
The study is envisioned to be conducted in two parts (FIG. 3). Part I: The study will initiate in approximately 24 adult (>18 y/o) subjects with SCD as a double-bind placebo-controlled randomized (2:1 active:placebo) study for up to 12 weeks of composition adminstration at 26.3 g BID (52.6 g/day). Based on ongoing tolerabilitiy and safety monitoring, the amounts and/or regimen of the composition may be adjusted downward. Part II: Pending the results from either the intérim analysis after Week 4 and/or the end-of-study results from Week 12 of Part I, Part II may subsequently initiate in a separate cohort of approximately eight additional adult (>18 y/o) and sixteen (16) adolescent (12-17 y/o) subjects. Anticipated amount of the composition for adult subjects in Part II is 17.4g BID (34.8 g/day); for adolescent subjects, amounts will be adjusted based 94 on their body weight (BW): 26.3g BID if BW >50kg and 17.4g BID if BW <50 kg. The amounts and/or regimen of composition may be further adjusted pending the results from Part I. There will be no separate placebo arm in Part II.
Part I & Part II: Baseline (Day 1) to Week 12: In Part I, randomization should occur approximately 3-5 days prior to the Day 1 visit and will be based on a 2:1 ratio of active:placebo. Assigned study composition [composition 26.3 g BID (52.6 g/day) or Placebo] will be shipped to the clinical site upon randomization of each subject. Once randomization has occurred, subjects will présent to the study site on Day 1 for their baseline assessments. In Part II, as there is no separate placebo arm, ail subjects will receive composition as either a fixed amount in adults (eg 17.4g BID), or body weight adjusted amounts in adolescent subjects (eg 26g BID if BW >50kg and 17.4g BID if BW <50 kg).
The composition is composed of amino acids. Placebo product is excipient matched to the composition. The study compositions are provided as dry powder in individual stick packs. Each stick pack contains -8.76 g of amino acids per stick pack. The prescribed number of stick packs for each administration [e.g. either 2, 3, or 4 stick packs BID] which are then mixed in -6 oz (-180 mL) of water, and then immediately consumed twice daily approximately 30 min (i.e., 30 ±5 minutes) before meals (e.g., before breakfast and dinner or before lunch and dinner, if breakfast is not a usual part of their daily routine) for the entire duration of the study.
SUMMARY OF EXAMPLES
Sickle cell disease is complex and driven by a multitude of unique mechanisms. Maintaining blood health and function requires coordination of many biological, cellular and molecular processes. As shown in the Examples herein, the amino acid compositions disclosed in this application (including LRQNacHKVSCitCar, RCitNacQCar, and RCitNac) were able to [1] mitigate inflammatory cytokines in human vascular endothélial cells, [2] reduce cellular adhesion molécule expression in human vascular endothélial cells, and [3] protect against insults to human RBC deformability, whereas compositions such as Q, RCit, and NAC were only able to influence some, but not ail of those important processes required for maintaining blood health. In fact, glutamine (Q) - which is FDA approved for the treatment of sickle cell disease - displayed négative or undesirable effects in particuiar assays herein that are mitigated in combinations.
While the invention has been particularly shown and described with reference to a preferred embodiment and varions altemate embodiments, it will be understood by persons skilled in the relevant art that varions changes in form and details can be made therein without departing from the spirit and scope of the invention.
Ail references, issued patents and patent applications cited within the body of the instant spécification are hereby incorporated by reference in their entirety, for ail purposes.
