Definitions
- the present invention relates to a method for providing alpha- 1 antitrypsin ( ⁇ l-AT) to a subject, in particular a method for providing to the subject a therapeutically or prophylactically effective amount of ⁇ l-AT by a subcutaneous route.
- the present invention also relates to a composition and article of manufacture for providing alpha-1 antitrypsin ( ⁇ l- AT), in particular subcutaneously.
- ⁇ l-AT deficiency is a relatively common genetic disorder that predisposes affected individuals to liver disease and/or pulmonary emphysema.
- the most common type of ⁇ l-AT deficiency termed protease inhibitor type Z (PiZ) is transmitted as an autosomal recessive trait and affects approximately 1 in 1700 live births in most Northern European and North American populations.
- the PiZ mutation is a single nucleotide substitution that results in a single amino acid substitution (glutamate 342 to lysine).
- ⁇ l-AT the major physiological function of ⁇ l-AT is the inhibition of neutrophil elastase, cathepsin G, and proteinase 3.
- the ⁇ l-AT produced in individuals with PiZ ⁇ l-AT deficiency is functionally active, although there may be a decrease in its specific elastase inhibitory capacity.
- the predominant site of ⁇ l-AT synthesis is the liver, however, it is also synthesized in extrahepatic cell types including macrophages, intestinal epithelial cells and intestinal Paneth cells.
- the half-life in plasma of type M ⁇ l-AT ( ⁇ l-ATM) (PiM is the normal allotype) is approximately five days.
- the half-life of the PiZ mutant protein ( ⁇ l-ATZ) is slightly less, but this difference is insufficient to account for the low plasma levels of ⁇ l-AT in homozygous PiZ individuals.
- ⁇ l-AT has been found to constitute greater than 90% of the neutrophil elastase inhibitor activity in pulmonary alveolar lavage fluid.
- the uninhibited activity of neutrophil elastase, cathepsin G, and proteinase 3 results in slow destruction of the connective tissue integrity of the lungs. This destruction of connective tissue leads to over distension and a reduction in the retractive force of the lungs which results in decreased expiratory airflow. Smoking exacerbates the problem by causing oxidative inactivation of what ⁇ l-AT is present.
- ⁇ l-AT supplement therapy has been employed in deficient individuals in the form of repeated intravenous administrations on a chronic basis.
- This mode of administration can be associated with problems including, for example, the requirement for a healthcare worker for administration, poor venous access, immediate hypersensitive reaction, high cost of the procedure, and wide fluctuations in the plasma levels of ⁇ l-AT.
- a method for providing ⁇ l-AT that at least is easy to administer is suitable for long-term administration, and achieves desirable ⁇ l-AT plasma bioavailability levels.
- the present invention provides a method for treating or preventing a disorder or disease associated with ⁇ l-AT deficiency in a subject in need of such treatment or prevention.
- the method comprises providing, subcutaneously, a therapeutically or prophylactically effective amount of ⁇ l-AT to the subject.
- the therapeutically or prophylactically effective amount of ⁇ l-AT is sufficient to maintain a blood ⁇ l-AT trough level of at least about 80 mg/dL.
- the present invention provides a method for treating or preventing a disorder or disease associated with ⁇ l-AT deficiency in a subject in need of such treatment or prevention.
- the method comprises: a) determining a therapeutically or prophylactically effective amount of ⁇ l-AT based on a dosing regimen comprising intravenously administered ⁇ l-AT; and b) providing a subcutaneous dose of at least about 120% of the therapeutically or prophylactically effective amount of ⁇ l-AT to the subject.
- an ⁇ l-AT formulation is provided for subcutaneous administration.
- the formulation is a lyophilized formulation, wherein prior to administration, the lyophilized formulation can be reconstituted with a suitable aqueous solution, for example an aqueous solution comprising water. Lyophilization and reconstitution of lyophilized formulations are generally known in the art.

- an individual subcutaneous administration of ⁇ l-AT comprises a volume of an ⁇ l-AT formulation, wherein the volume is administered over a duration of administration.
- the volume will of course depend in part on the concentration of ⁇ l-AT in the formulation to be administered. Moreover, the duration of administration can depend on one or more factors including, but not limited to the volume that is administered and the subject's discomfort level. For example, a dose having a relatively large volume can be provided as separate smaller volumes that can be administered at the same or a different time to the same or a different subcutaneous site (e.g., simultaneous administration of two smaller volumes to two different subcutaneous sites). In one embodiment, the volume that is administered at a subcutaneous site is less than about 3 mL.

- parenteral injection including, but not limited to, subcutaneous, intramuscular, intraorbital, intracapsular, and intravenous injection.
- the route of administration and the amount of the one or more reagents administered can vary according to various subject variables including size, weight, age, disease severity, and responsiveness to therapy. Methods for determining the appropriate route of administration and dosage of the one or more reagents can generally be determined on a case-by-case basis. Such determinations are routine to one of ordinary skill in the art (see, for example; Harrison's Principles of Internal Medicine, 1 lth Ed., 1987).
- the one or more reagents is a hydrolase such as, for example, a glycosidase.
- a glycosidases includes hyaluronidase, ⁇ - amylase, ⁇ -amylase, keratanase, dextranase, endoglycoceramidase II, chitosanase, chitinase, thioglucosidase, pectinase, pectolyase, lysozyme , neuraminidase, ⁇ -glucosidase, ⁇ - glucosidase, ⁇ -galactosidase, ⁇ -galactosidase, ⁇ -mannosidase, invertase, trehalase, amyloglucosidase, ⁇ -glucuronidase, hyaluronidase, cellulase, trehalase, amyloglucos
- the glycosidase is a hyaluronidase.
- the hyaluronidase can be an enzyme that is capable of cleaving ⁇ -N-acetylhexosamine-(l-4)- glycosidic bonds in hyaluronic acid, chondroitin, and/or chondroitin sulfates.
- the hyaluronidase can be administered as an adjuvant to increase the absorption of ⁇ l-AT thereby enhancing its pharmacokinetics and/or pharmacodynamics.
- hyaluronidase can act as a spreading or diffusing substance which modifies the permeability of connective tissue through the hydrolysis of hyaluronic acid, a polysaccharide found in the intercellular ground substance of connective tissue, and of certain specialized tissues, such as the umbilical cord and vitreous humor.
- Hyaluronidase at least can hydrolyze hyaluronic acid by splitting the glucosaminidic bond between Cl of the glucosamine moiety and C4 of glucuronic acid. It is believed that this can temporarily decrease the viscosity of the cellular cement and promote diffusion of injected fluids or of localized transudates or exudates, thus facilitating their absorption.
- the rate of diffusion can be proportionate to the amount of enzyme, and the extent can be proportionate to the volume of solution.
- Knowledge of the mechanisms involved in the disappearance of injected hyaluronidase is limited, however, it is believed that the blood of a number of mammalian species brings about the inactivation of hyaluronidase.
- the specific dosage appropriate for administration can be readily determined by one of ordinary skill in the art and/or according to the factors discussed herein.
- one of ordinary skill in art will recognize that the estimates for appropriate dosages in humans can be extrapolated from determinations of the level of enzymatic activity of the enzyme in vitro and/or dosages effective in animal studies.
- X units (U) of hyaluronidase can be effective in enhancing the pharmacokinetics and/or pharmacodynamics of a subcutaneously administered ⁇ l-AT regimen in a rabbit weighing about 3 kg and, given this information, the corresponding hyaluronidase dosages in a human weighing about 75 kg could be about 25 times ( e.g., about 25 times X units) the effective dose in the rabbits.
- a number of hyaluronidase injections are known such as, for example, formulations marketed as AmphadaseTM (150 units/mL injectable solution), HydaseTM (150 units/mL injectable solution), HylenexTM (150 units/mL injectable solution), VitraseTM (200 units/mL injectable solution), and VitraseTM (6200 units injection).
- AmphadaseTM (Amphastar Pharmaceuticals, Inc., Collinso Cucamonga, CA) is a preparation of purified bovine testicular hyaluronidase supplied as a sterile, colorless, ready for use solution, and absorption and dispersion of other injected drugs may be enhanced by adding 50-300 Units AmphadaseTM, typically 150 U AmphadaseTM, to the injection solution.
- Each vial of AmphadaseTM contains 150 USP units of hyaluronidase per mL with 8.5 mg sodium chloride, 1 mg edetate disodium, 0.4 mg calcium chloride, monobasic sodium phosphate buffer, and not more than 0.1 mg thimerosal (mercury derivative).
- the ready for use solution is clear and colorless with an approximate pH of 6.8 and an osmolality of 295 to 355 mOsm.

- C max in about 48hrs.
- the fractional availability (F) derived from the area under concentration curve's (AUCs) of SC-I (i.e., 100% IV dose) and SC-2 (i.e., 120% of IV dose) group were, respectively, 27% lower (PO.05) and 8% lower (not statistically significant) compared to the IV group.
- the results are summarized in Table 1.
- Rabbits were prepared as above and assigned to three groups and dosed on day 0, 2, 4, and 6.
- Group 1 rabbits i.e., SC-3
- Group 2 rabbits i.e., SC-4
- Group 3 rabbits i.e., SC-5
- Blood samples were collected atl, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 12 days post dosing and processed as above for analysis.
- the plasma levels of subcutaneously administered ⁇ l-AT in all the three groups continued to rise with repeated administration up to day 7 and thereafter the levels gradually declined towards baseline by day 12.
- the AUC of SC-3, SC-4, and SC-5 were 127 ⁇ 11, 159 ⁇ 8, and 162 ⁇ 12, respectively.
- the fractional availability (F) which was determined by comparing the AUC to the single dose IV group from the experiment described in Example 1 above, was 0.71 ⁇ 0.03, 0.89 ⁇ 0.04, 0.91 ⁇ 0.07 for SC-3, SC-4, and SC-5, respectively.
- the F value for SC-3 was lower than SC- 4 and SC-5 by about 20% (PO.05).
- Table 2 The results are summarized in Table 2.
- test articles (10ml h-AT - 56mg/ml - Lot # T06AU02) or vehicle (phosphate buffer saline) were administered by SC injection by a 23- gauge butterfly catheter.
- the animal skin was immobilized by gentle traction and the butterfly needle from the catheter was inserted into the space between the skin and the underlying subcutaneous tissue to ensure that there is minimal movement of the needle to avoid injury of the tissues.
- the test articles were administered SC at the same site for each rabbit and the injection site and tissue distortion borders were marked with a marker. The injections as outlined above were repeated each day for three consecutive days.
- Tissue collection times are outlined in the Table 3 above.
- the animals were anesthetized with ketamine (50 mg/kg b/w) and xylazine (lOmg/kg b/w) intramuscularly (IM) and euthanized by pentobarbital (120 mg/kg or 7mls per 3 kg rabbit) administered intravenously (IV).
- IM ketamine
- xylazine lOmg/kg b/w
- pentobarbital 120 mg/kg or 7mls per 3 kg rabbit

- the tissue was marked dorsal, ventral, cranial and caudal with a marker.
- the dorso-cranial corner of the squared tissue section was cut off to further provide orientation for sectioning and histopathology.
- FIG. 3 A slides 1-5 shows that there was no indication of inflammation or signs of injury in rabbits treated with h-AT or vehicle compared to untreated control suggesting that repeated SC administration of h-AT did not alter skin and underlying tissue histology.
- Figure 3B lungs from rabbits treated with vehicle (slides 1 & 2) did not show dark staining indicating the lack of h-AT, however, rabbits treated with h-AT (slides 3 & 4) showed dark staining indicating the presence of h-AT throughout the lung tissue including epithelial, endothelial, and interstitial space.
- rabbits were administered ⁇ l-AT with or without hyaluronidase.
- h-AT - Intravenous Rabbits were treated with acepromazine (1.0 mg/kg bw) by SC injection to cause vasodilation of the veins and arteries in the ears.
- h-AT (Lot # T06Au02- 56mg/ml - Talecris Biotherapeutics) was administered [200mg/kg bwl ⁇ .7] as a bolus in the ear vein via a butterfly needle attached to the syringe.
- Samples were analyzed for human- AT by immunonephelometry. Data were analyzed by Microsoft Excel (Microsoft, Seattle, WA) and pharmacokinetic parameters such as area- under-the-curve (AUC), fractional availability (F), half-life (T 1/2), maximal plasma concentration (C max ), and maximum time for peak plasma concentration (T max ), etc were determined by using WinNonlin 5.2 (Pharsight Corp, Mountain view CA). Graphs were plotted using Sigma Plot 8.0 (Systat Software, Inc, San Jose, CA). Data was subjected to statistical analysis using JMP 7.0 (SAS, Cary, NC).
