Definitions

  • Age-related loss of muscle mass and function is inevitable in all individuals; however its progression largely depends on genetic and environmental factors such as physical activity and nutritional intake, including adequate intake of vitamins.
  • Sarcopenia has been defined as the point where the age-related loss of muscle mass and function gets debilitating and impacts quality of life. In contrast, frailty is another classification of age-related physical function decline that features low muscle strength and functionality, but not muscle mass.
  • Sarcopenia is defined clinically according to low muscle mass and function, using cutoffs which stratify the elderly population for individuals in a state of pathological mobility. Muscle loss and related diseases such as cachexia or sarcopenia have important clinical implications because they are associated with increased morbidity and mortality.
  • cachexia and sarcopenia are important areas of research for development in humans, they are beginning to be recognized in veterinary medicine (L M Freeman, 2012, J Vet Intern Med. 26(1) 3-17).
  • NAD+ is an enzyme co-factor that is essential for the function of several enzymes related to reductionoxidation reactions and energy metabolism.
  • NAD+ functions as an electron carrier in cell metabolism of amino acids, fatty acids, and carbohydrates.
  • NAD+ serves as an activator and substrate for sirtuins, a family of protein deacetylases that have been implicated in metabolic function and extended lifespan in lower organisms.
  • sirtuins a family of protein deacetylases that have been implicated in metabolic function and extended lifespan in lower organisms.
  • the co-enzymatic activity of NAD+ together with the tight regulation of its biosynthesis and bioavailability, makes it an important metabolic monitoring system that is clearly involved in the aging process and important for production of energy to allow skeletal muscle to properly function.
  • Mitochondria are the primary source of aerobic energy production in mammalian cells and also maintain a large Ca2+ gradient across their inner membrane, providing a signaling potential for this molecule.
  • mitochondrial Ca2+ plays a role in the mitochondria in the regulation of ATP generation and potentially contributes to the orchestration of cellular metabolic homeostasis. Specifically, activation of mitochondrial Ca2+ import increases cellular energy metabolism (Glancy, B. and R. S. Balaban (2012). "Role of mitochondrial Ca2+ in the regulation of cellular energetics.” Biochemistry 51 (14): 2959-2973).
  • Age-related decrease in muscle mass is responsible for almost all loss of strength and power in older individuals, with an increase in fatigue. This decrease is due to inter-related factors: lifestyle, structural changes of the muscle, and metabolic changes.
  • oleuropein and/or metabolites thereof are bioactives that activate mitochondrial calcium in combination with trigonelline.
  • Calcium is essential for skeletal muscle contraction, but there are very limited solutions to increase mitochondrial calcium uptake through natural bioactives in order to influence bioenergetics. Therefore, without being bound by theory, the present inventors believe that a combination of trigonelline and at least one of oleuropein or metabolite thereof increases muscle energy metabolism and mitochondrial function, which in turn can increase muscle mass, functionality and performance.
  • the present disclosure provides a method of achieving at least one result selected from the group consisting of (i) improved mitochondrial calcium uptake in muscle cells, (ii) improved utilization of calcium in muscle cells, (iii) increased mitochondrial energy in muscle cells, (iv) improvement in at least one of muscle functionality, muscle performance, lean muscle mass or muscle strength, (v) decreased muscle fatigue, (vi) increased mobility and (vii) treatment or prevention of a muscle disorder linked to calcium depletion or deficiency (e.g., reduction in incidence and/or severity) (viii) increasing NAD+ levels in skeletal muscle to prevent and/or treat skeletal muscle diseases and/or conditions.
  • the method comprises orally administering to a pet animal an effective amount of a combination of trigonelline and at least one of oleuropein and/or metabolite thereof.

Description

COMPOSITIONS AND METHODS USING TRIGONELLINE AND OLEUROPEIN FOR PREVENTING OR TREATING CONDITIONS OR DISORDERS IN SKELETAL MUSCLE IN A PET ANIMAL
BACKGROUND OF THE INVENTION
Age-related loss of muscle mass and function is inevitable in all individuals; however its progression largely depends on genetic and environmental factors such as physical activity and nutritional intake, including adequate intake of vitamins. Sarcopenia has been defined as the point where the age-related loss of muscle mass and function gets debilitating and impacts quality of life. In contrast, frailty is another classification of age-related physical function decline that features low muscle strength and functionality, but not muscle mass. Sarcopenia is defined clinically according to low muscle mass and function, using cutoffs which stratify the elderly population for individuals in a state of pathological mobility. Muscle loss and related diseases such as cachexia or sarcopenia have important clinical implications because they are associated with increased morbidity and mortality.
Whereas cachexia and sarcopenia are important areas of research for development in humans, they are beginning to be recognized in veterinary medicine (L M Freeman, 2012, J Vet Intern Med. 26(1) 3-17).
Trigonelline is an important NAD+ precursor which feeds into the NAD+ pathway. NAD+ is an enzyme co-factor that is essential for the function of several enzymes related to reductionoxidation reactions and energy metabolism. NAD+ functions as an electron carrier in cell metabolism of amino acids, fatty acids, and carbohydrates. NAD+ serves as an activator and substrate for sirtuins, a family of protein deacetylases that have been implicated in metabolic function and extended lifespan in lower organisms. The co-enzymatic activity of NAD+, together with the tight regulation of its biosynthesis and bioavailability, makes it an important metabolic monitoring system that is clearly involved in the aging process and important for production of energy to allow skeletal muscle to properly function.
Moreover, Mitochondria are the primary source of aerobic energy production in mammalian cells and also maintain a large Ca2+ gradient across their inner membrane, providing a signaling potential for this molecule. Furthermore, mitochondrial Ca2+ plays a role in the mitochondria in the regulation of ATP generation and potentially contributes to the orchestration of cellular metabolic homeostasis. Specifically, activation of mitochondrial Ca2+ import increases cellular energy metabolism (Glancy, B. and R. S. Balaban (2012). "Role of mitochondrial Ca2+ in the regulation of cellular energetics." Biochemistry 51 (14): 2959-2973).
The present inventors noted that advancing age includes a gradual decrease in muscle function, capacity and reactivity, associated with a decline in muscle mitochondrial function. Age-related decrease in muscle mass is responsible for almost all loss of strength and power in older individuals, with an increase in fatigue. This decrease is due to inter-related factors: lifestyle, structural changes of the muscle, and metabolic changes.
The present inventors recognized this problem and addressed it by the surprising discovery that oleuropein and/or metabolites thereof are bioactives that activate mitochondrial calcium in combination with trigonelline. Calcium is essential for skeletal muscle contraction, but there are very limited solutions to increase mitochondrial calcium uptake through natural bioactives in order to influence bioenergetics. Therefore, without being bound by theory, the present inventors believe that a combination of trigonelline and at least one of oleuropein or metabolite thereof increases muscle energy metabolism and mitochondrial function, which in turn can increase muscle mass, functionality and performance.

DETAILED DESCRIPTION OF THE INVENTION
Definitions
All percentages are by weight of the total weight of the composition unless expressed otherwise. Similarly, all ratios are by weight unless expressed otherwise. When reference is made to the pH, values correspond to pH measured at 25 °C with standard equipment. As used herein, “about,” “approximately” and “substantially” are understood to refer to numbers in a range of numerals, for example the range of -10% to +10% of the referenced number, preferably -5% to +5% of the referenced number, more preferably -1 % to +1 % of the referenced number, most preferably -0.1 % to +0.1 % of the referenced number.
Furthermore, all numerical ranges herein should be understood to include all integers, whole or fractions, within the range. Moreover, these numerical ranges should be construed as providing support for a claim directed to any number or subset of numbers in that range. For example, a disclosure of from 1 to 10 should be construed as supporting a range of from 1 to 8, from 3 to 7, from 1 to 9, from 3.6 to 4.6, from 3.5 to 9.9, and so forth.
As used herein and in the appended claims, the singular form of a word includes the plural, unless the context clearly dictates otherwise. Thus, the references “a,” “an” and “the” are generally inclusive of the plurals of the respective terms. For example, reference to “an ingredient” or “a method” includes a plurality of such “ingredients” or “methods.” The term “and/or” used in the context of “X and/or Y” should be interpreted as “X,” or “Y,” or “X and Y.” Similarly, “at least one of X or Y” should be interpreted as “X,” or “Y,” or “both X and Y.”
Similarly, the words “comprise,” “comprises,” and “comprising” are to be interpreted inclusively rather than exclusively. Likewise, the terms “include,” “including” and “or” should all be construed to be inclusive, unless such a construction is clearly prohibited from the context. However, the embodiments provided by the present disclosure may lack any element that is not specifically disclosed herein. Thus, a disclosure of an embodiment defined using the term “comprising” is also a disclosure of embodiments “consisting essentially of’ and “consisting of’ the disclosed components. “Consisting essentially of’ means that the embodiment comprises more than 50 wt.% of the identified components, preferably at least 75 wt.% of the identified components, more preferably at least 85 wt.% of the identified components, most preferably at least 95 wt.% of the identified components, for example at least 99 wt.% of the identified components.
Where used herein, the term “example,” particularly when followed by a listing of terms, is merely exemplary and illustrative, and should not be deemed to be exclusive or comprehensive. Any embodiment disclosed herein can be combined with any other embodiment disclosed herein unless explicitly indicated otherwise. Accordingly, the terms “subject”, “individual” and “patient” refer to any pet animal that can benefit from the methods and compositions disclosed herein. “Pet animal” includes, but is not limited to, mammals, which includes but is not limited to rodents; aquatic mammals; domestic animals such as dogs, cats and other pets; farm animals such as sheep, pigs, cows and horses;
For animals, such as a companion animal (i.e. , cat or dog), an “older adult” or “ageing individual” has exceeded 50% of the average lifespan for its particular species and/or breed within a species.
The term “elderly” means a pet animal subject that has reached 60% of its likely lifespan, in some embodiments at least 70%, at least 80% or at least 90% of its likely lifespan. A determination of lifespan may be based on actuarial tables, calculations, or estimates, and may consider past, present, and future influences or factors that are known to positively or negatively affect lifespan. Consideration of species, gender, size, genetic factors, environmental factors and stressors, present and past health status, past and present nutritional status, and stressors may be taken into consideration when determining lifespan. An ageing cat or dog has an age from birth of at least about 5 years. An elderly or senior cat or dog has an age from birth of at least about 7 years.
“Muscle fatigue” means a reduced contractile force in one or more muscles due to a shortage of substrates within the muscle fiber and/or an accumulation of metabolites within the muscle fiber which interfere either with the release of calcium or with the ability of calcium to stimulate muscle contraction.
“Muscle weakness” is a condition where the force exerted by the muscles is less than would be expected. The U.S. Medical Research Council’s grading system for muscle strength is widely used to identify muscle weakness and the severity thereof. Specifically, the examiner assesses the patient’s ability to move the muscle against resistance provided by the examiner who, through experience, has developed a sense of the expected range of normal. This will vary from patient-to-patient depending upon the underlying size and conditioning of the subject; the fully trained athlete can be expected to perform differently from a small, sedentary, or deconditioned pet animal. The expected strength should also be adjusted for degree of atrophy in individualss with wasting illnesses. As used herein, a “athlete pet animal” is an individual who participates in at least one of 1) resistance exercise, 2) anaerobic or repeated sprint-type exercise, or 3) endurance exercise.
Sarcopenia
“Sarcopenia” is defined as the age-associated loss of muscle mass and functionality (including muscle strength and gait speed). Sarcopenia can be characterized by one or more of low muscle mass, low muscle strength and low physical performance.
Few studies investigating sarcopenia have been conducted in dogs and cats, but available information suggests that dogs and cats also lose LBM during aging. (Harper EJ. J Nutr 1998;128:2627S-2631S.). These data support the existence of a similar age-related loss of LBM as is seen in people. Although sarcopenia could be identified in healthy geriatric dogs by clinically relevant techniques, differences in pathophysiological mechanisms were not found, and additional research will be needed to identify both mechanisms and potential therapeutic targets (L M Freeman, 2012, J Vet Intern Med. 26(1) 3-17).
As used herein, “frailty” is defined as a clinically recognizable state of increased vulnerability resulting from aging-associated decline in reserve and function across multiple physiologic systems such that the ability to cope with everyday or acute stressors is compromised.
Cachexia and related diseases
Cachexia is the loss of lean body mass (LBM) that affects a large proportion of dogs and cats with congestive heart failure (CHF), chronic kidney disease (CKD), cancer, and a variety of other chronic diseases (L M Freeman, 2012, J Vet Intern Med. 26(1) 3-17).
Myopathy and related conditions
Myopathies are neuromuscular disorders in which the primary symptom is muscle weakness due to dysfunction of muscle fiber. Other symptoms of myopathy can include muscle cramps, stiffness, and spasm. Myopathies can be inherited (such as the muscular dystrophies) or acquired (such as common muscle cramps). Recovery after Muscle Injury from Surgery and Muscle Traumas
Muscle injuries can be caused by bruising, stretching or laceration causing acute or chronic soft tissue injury that occurs to a muscle, tendon, or both. It may occur as a result of fatigue, overuse, or improper use of a muscle. It may occur after physical trauma such as a fall, fracture or overuse during physical activity. Muscle injuries may also occur after surgery such as joint replacement arthroscopic surgery.
The terms “treatment” and “treating” include any effect that results in the improvement of the condition or disorder, for example lessening, reducing, modulating, or eliminating the condition or disorder. The term does not necessarily imply that a subject is treated until total recovery. Non-limiting examples of “treating” or “treatment of’ a condition or disorder include: (1) inhibiting the condition or disorder, i.e., arresting the development of the condition or disorder or its clinical symptoms and (2) relieving the condition or disorder, i.e., causing the temporary or permanent regression of the condition or disorder or its clinical symptoms. A treatment can be patient- or doctor-related.
The terms “prevention” or “preventing” mean causing the clinical symptoms of the referenced condition or disorder to not develop in an individual that may be exposed or predisposed to the condition or disorder but does not yet experience or display symptoms of the condition or disorder. The terms “condition” and “disorder” mean any disease, condition, symptom, or indication.
The relative terms “improved,” “increased,” “enhanced” and the like refer to the effects of the composition comprising a combination of trigonelline and high protein (disclosed herein) relative to a composition with less protein but otherwise identical.
The terms “food,” “food product” and “food composition” mean a product or composition that is intended for ingestion by an individual such as a pet animal and provides at least one nutrient to the individual. The compositions of the present disclosure, including the many embodiments described herein, can comprise, consist of, or consist essentially of the essential elements and limitations described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful in a diet.
The term “beverage”, “beverage product” and “beverage composition” mean a product or composition for ingestion by an individual such as a pet animal and provides at least one nutrient to the individual. The compositions of the present disclosure, including the many embodiments described herein, can comprise, consist of, or consist essentially of the essential elements and limitations described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful in a diet.
As used herein, “complete nutrition” contains sufficient types and levels of macronutrients (protein, fats and carbohydrates) and micronutrients to be sufficient to be a sole source of nutrition for the subject to which the composition is administered. Individuals can receive 100% of their nutritional requirements from such complete nutritional compositions.
The term “enterally administering” encompasses oral administration (including oral gavage administration), as well as rectal administration, although oral administration is preferred. The term "parenterally administering" refers to delivery of substances given by routes other than the digestive tract and covers administration routes such as intravenous, intra-arterial, intramuscular, intracerebroventricular, intraosseous, intradermal, intrathecal, and also intraperitoneal administration, intravesical infusion and intracavernosal injection.
Preferred parenteral administration is intravenous administration. A particular form of parenteral administration is delivery by intravenous administration of nutrition. Parenteral nutrition is “total parenteral nutrition” when no food is given by other routes. “Parenteral nutrition” is preferably a isotonic or hypertonic aqueous solution (or solid compositions to be dissolved, or liquid concentrates to be diluted to obtain an isotonic or hypertonic solution) comprising a saccharide such as glucose and further comprising one or more of lipids, amino acids, and vitamins.

In some embodiments, the combination of trigonelline and at least one of oleuropein or metabolite thereof is administered to a pet animal selected from the group consisting of an aging subject; an elderly subject; a subject with muscle fatigue or muscle weakness; a subject with impaired mobility; a frail subject; a pre-frail subject; a sarcopenic subject; a subject recovering from pre-frailty, frailty, sarcopenia or impaired mobility; a subject undergoing physical rehabilitation (e.g., from an injury to one or more of a muscle, a bone, a ligament, or the nervous system) and an athlete pet.
In some embodiments, the pet animal is healthy.
In some embodiments, the pet animal has sarcopenia, frailty, muscle fatigue or muscle weakness, or impairment in one or more of muscle functionality, muscle performance, lean muscle mass or muscle strength, but optionally is otherwise healthy.
For example, the combination of trigonelline and at least one of oleuropein or metabolite thereof can be administered to an athlete pet before, during and/or after exercise, for example less than two hours before the exercise or less than one hour before the exercise and less than two hours after the exercise or less than one hour after the exercise.
The composition of the invention can be administered to a pet animal, e.g., an ageing pet animal or a critically ill pet animal, or a pet animal recovering from surgery or injury of the skeletal muscle; in a therapeutically effective dose. The therapeutically effective dose can be determined by the person skilled in the art and will depend on a number of factors known to those of skill in the art, such as the severity of the condition and the weight and general state of the pet animal.
The composition is preferably administered to the pet animal at least two days per week, more preferably at least three days per week, most preferably all seven days of the week; for at least one week, at least one month, at least two months, at least three months, at least six months, or even longer. In some embodiments, the composition is administered to the pet animal consecutively for a number of days, for example at least until a therapeutic effect is achieved. In an embodiment, the composition can be administered to the pet animal daily for at least 30, 60 or 90 consecutive days.
The above examples of administration do not require continuous daily administration with no interruptions. Instead, there may be some short breaks in the administration, such as a break of two to four days during the period of administration. The ideal duration of the administration of the composition can be determined by those of skill in the art.
In a preferred embodiment, the composition is administered to the pet animal orally or enterally (e.g. tube feeding). For example, the composition can be administered to the pet animal as a beverage, a capsule, a tablet, a powder or a suspension.
The composition can be any kind of composition that is suitable for pet animal consumption. For example, the composition may be selected from the group consisting of food compositions, dietary supplements, nutritional compositions, nutraceuticals, powdered nutritional products to be reconstituted in water or milk before consumption, food additives, medicaments, beverages and drinks. In an embodiment, the composition is an oral nutritional supplement (ONS), a complete nutritional formula, a pharmaceutical, a medical or a food product. In a preferred embodiment, the composition is administered to the pet animal as a beverage. The composition may be stored in a sachet as a powder and then suspended in a liquid such as water for use.
In some instances where oral or enteral administration is not possible or not advised, the composition may also be administered parenterally.
In some embodiments, the composition is administered to the pet animal in a single dosage form, i.e. all compounds are present in one product to be given to an pet animal in combination with a meal. In other embodiments, the composition is co-administered in separate dosage forms, for example at least one component separately from one or more of the other components of the composition.
These methods can consist essentially of administering the composition consisting essentially of trigonelline and oleuropein or metabolite thereof.
Unit dosage forms for oral or rectal administration such as syrups, elixirs, and suspensions may be provided wherein each dosage unit, for example, teaspoonful, tablespoonful, tablet or suppository, contains a predetermined amount of the composition. Similarly, unit dosage forms for injection or intravenous administration may comprise the compounds in a composition as a solution in sterile water, normal saline or another pharmaceutically acceptable carrier, wherein each dosage unit, for example, mL or L, contains a predetermined amount of the composition containing one or more of the compounds.
The above examples of administration do not require continuous daily administration with no interruptions. Instead, there may be some short breaks in the administration, such as a break of two to four days during the period of administration. The ideal duration of the administration of the composition can be determined by those of skill in the art.
In an embodiment, the trigonelline and the at least one of oleuropein or metabolite thereof can be administered in the same composition, for example a unit dosage form containing both the trigonelline and the at least one of oleuropein or metabolite thereof.
In an alternative embodiment, the trigonelline and the at least one of oleuropein or metabolite thereof can be administered sequentially in separate compositions. The term “sequentially” means that the trigonelline and the at least one of oleuropein or metabolite thereof are administered in a successive manner such that the at least one of oleuropein or metabolite thereof is administered at a first time without the trigonelline, and the trigonelline is administered at a second time (before or subsequent to the first time) without the at least one of oleuropein or metabolite thereof. The time between sequential administrations may be, for example, one or several seconds, minutes or hours in the same day; one or several days or weeks in the same month; or one or several months in the same year.

EXAMPLE
Comparative effect of combination of oleuropein and Trigonelline vs single compounds on mitochondrial activation in muscle cells
Materials and Methods
To test the effect of Oleuropein aglycone (Oea), Trigonelline and their combination on mitochondrial activation in living cells, the inventors measured mitochondrial calcium elevation in myotubes differentiated from C2C12 cells.
C2C12 cells were purchased from ATCC. C2C12 cells were seeded in 384-well plates at a density of 4500 cells per well in DMEM medium, high glucose (Gibco) + 10% fetal calf serum. Myotubes were differentiated from C2C12 cells by growing the cells in DMEM containing 2% horse serum, for 6 days. Mitochondrial calcium measurements were carried out using myotubes infected with the adenovirus (from Sirion biotech) expressing the luminescent mitochondrially-targeted calcium sensor mitochondrial mutated aequorin (Montero et al., 2000). For aequorin reconstitution, 48 hours after infection, myotubes were incubated for 2h at room temperature (22 ±°C) in standard Aequorin buffer (145 mM NaCI, 5 mM KCI, 1 mM MgCI2, 1 mM CaCI2, 10 mM glucose and 10 mM Hepes, pH 7.4) with 1 pM wild type coelenterazine. For treatment, Trigonelline Iodine (0 pM, buffer, or 500 pM, as indicated in the figures) and Oleuropein aglycone (3 pM or 10 pM, as indicated in the figures) were incubated for 2h in Aequorin buffer. Myotubes were stimulated with 5 mM of caffeine and the total calcium transiting during stimulation was calculated as the area under the curve, during caffeine stimulation. Luminescence was measured at the FLIPR cell imaging reader (Molecular devices). Calibration of the luminescence data into Calcium concentration was carried out using an algorithm as described previously (Bonora et al., 2013). Custom module analysis based on Excel (Microsoft) and GraphPad Prism 7.02 (GraphPad) software was used for quantification. Results
As shown in FIG. 1 and FIG.2, the combination of Trigonelline and Oleuropein promotes the beneficial effects of the 2 compounds by boosting the calcium uptake into the mitochondria.
