Description

Background Art

[0001] Acid sphingomyelinase deficiency (ASMD) is a rare lysosomal storage disorder that threatens life. It is an autosomal recessive genetic disease caused by mutations in the SMPD1 gene that encodes the lysosomal enzyme acid sphingomyelinase (ASM) (Non-Patent Document 1). ASMD patients cannot metabolize sphingomyelin, and as a result, it accumulates in the lysosomes of multiple organs, and in severe cases, causes visceral diseases and neurodegeneration. ASMD patients have increased cholesterol and other lipids in the spleen, liver, lungs, and bone marrow.

[0002] Infantile visceral neuropathy ASMD (also known as Niemann-Pick disease type A or NPD A) is the most severe disease phenotype and is characterized by early onset and an acute neuropathy type. NPD A causes growth disorders, hepatosplenomegaly, and rapidly progressive neurodegeneration. Patients die in infancy (Non-Patent Document 2).

[0003] Patients with chronic visceral ASMD (NPD B) and chronic visceral neuropathy ASMD (NPD A / B) develop from infancy to adulthood (Non-Patent Documents 3; Non-Patent Document 4). NPD B patients are usually diagnosed in childhood, typically after the age of 2. Most NPD B patients live to adulthood. NPD A / B patients are classified as an intermediate type presenting neurological symptoms in childhood that may develop into a neurodegenerative disease. The morbidity rates due to liver, lung, and hematopoietic system diseases occur in all patients with chronic ASMD and include hepatosplenomegaly, liver dysfunction, infiltrative lung disease, and thrombocytopenia (Non-Patent Documents 5; Non-Patent Document 6). Bone disorders such as growth restriction in childhood and low bone density are also common features of chronic ASMD (Non-Patent Document 7). The main causes of death in these patients are lung disease and liver disease (Non-Patent Documents 8; Non-Patent Document 9).

[0004] Due to the high morbidity and mortality rates of ASMD, effective treatment for this genetic disease is urgently desired.

[0024] The present invention provides compositions comprising recombinant human ASM, for example, olipidase alfa, and one or more pharmaceutically acceptable excipients. The compositions of this disclosure have improved stability and shelf life compared to other compositions. In some embodiments, the compositions of the present invention are pharmaceutical compositions, i.e., compositions that can be prepared such that the biological activity of the active ingredient is effective, while not containing additional ingredients that are highly toxic or otherwise cause undesirable side effects in the patient that are unrelated to the active ingredient. The terms “pharmaceutical composition” and “pharmaceutical formulation” are used interchangeably herein. The pharmaceutical compositions of the present invention are useful for treating patients with ASM deficiency, as further described below.

[0025] Recombinant human acid sphingomyelinase ASM is an enzyme that catalyzes the breakdown of sphingomyelin into ceramide and phosphorylcholine. "Recombinant human ASM" is prepared by recombinant means and compared to the wild-type sequence. This refers to human ASM with or without specific amino acid modifications. For example, recombinant human ASM is expressed in cultured mammalian host cells (e.g., COS, CHO, HeLa, 3T3, 293T, NS0, SP2 / 0, or HuT 78 cells) or in animals transgenic to human ASM coding sequences.

[0026] In some embodiments, recombinant human ASM is olipudase alpha. Olipudase alpha is the glycoform alpha of human ASM (EC-3.1.4.12) produced in CHO cells. Mature olipudase alpha is a 570-amino acid polypeptide that retains the enzymatic and lysosomal targeting activity of the native human protein. The amino acid sequence of olipudase alpha, including the leader sequence (residues 1-57), is shown below as Sequence ID No. 1, where the leader sequence is italicized and in bold. The mature olipudase alpha sequence (Sequence ID No. 2, relating to residues 58-627 of Sequence ID No. 1) does not have a leader sequence.

[0027] [ka]

[0028] In other embodiments, the human ASM useful in the present invention has an amino acid sequence that is 99%, 98%, 97%, 96%, or 95% identical to that of olipidase alpha. For example, the human ASM in the composition may have the sequence shown in U.S. Patent No. 6,541,218, the disclosure of which is incorporated herein by reference in its entirety. The sequence (SEQ ID NO: 3) is shown below with the leader sequence (residues 1-59) in italics and bold, where the mature protein (SEQ ID NO: 4 relating to residues 60-629 of SEQ ID NO: 3) does not have a leader sequence.

[0029] [ka]

[0030] The human ASM in the composition may also be identical in amino acid sequence to the human ASM disclosed in the UNIPROT database as sequence P17405-1 or its polymorphic variant. The P17405-1 sequence is shown below with the leader sequence (residues 1-59) in italics and bold (SEQ ID NO: 5), where the mature protein (SEQ ID NO: 6, relating to residues 60-629 of SEQ ID NO: 5) does not have a leader sequence.

[0031] [ka]

[0032] Recombinant human acid sphingomyelinase composition The compositions of the present invention contain recombinant human ASM and exhibit excellent stability with respect to the enzyme. "Stability" refers to the ability of the active ingredients in the composition to maintain their physical stability, chemical stability, and / or biological activity during storage and / or when subjected to physical or chemical stress. Stability may be under selected conditions, e.g., refrigerated conditions (e.g., 2–8°C) or room temperature (e.g., 23–25°C), for selected periods, e.g., 16 weeks, 24 weeks, 36 weeks, 4 months, 6 months, 1 year, 2 years, 3 years, or longer. Protein stability is measured by assays performed over shorter periods, but whose results indicate stability in a clinical setting. Such assays include freeze / thaw assays in which the protein composition is subjected to one or more freeze-thaw cycles; or agitation assays in which the protein composition is subjected to mechanical agitation over a predetermined period. The stability of a protein can be determined by storing the protein composition at a specified storage temperature (e.g., 2–8°C) for a selected period and analyzing its structural and functional attributes, such as the degree of dimerization or aggregation (e.g., measured by size exclusion HPLC or protein gel), proteolysis (e.g., measured by size exclusion HPLC or protein gel), color change of the composition, clarity of the liquid composition, enzyme activity, glycan content and composition, receptor binding affinity, methionine residual oxidation, and the biological activity of the composition.

[0033] The compositions of the present invention comprise one or more pharmaceutically acceptable excipients. “Excipient” refers to an inert substance used as a diluent, vehicle, carrier, preservative, binder, or stabilizer for the active ingredient of a drug. For example, a composition may include stabilizers such as buffers, isotonic agents, and / or antioxidants. In some cases, one agent may perform multiple of these purposes. In some embodiments, the compositions of the present invention comprise recombinant human ASM such as olipudase alpha, buffers such as sodium phosphate or sodium citrate, stabilizers such as L-methionine, and non-reducing sugars such as sucrose or trehalose. Human ASM exhibits improved stability due to specific compositional features. The compositions of the present invention may be aqueous solutions or lyophilized preparations.

[0034] liquid composition In some embodiments, the composition is an aqueous liquid composition comprising 1-10 mg / mL (e.g., 3-5 mg / mL) rhASM (e.g., olipudase alpha); 10-50 mM (e.g., 10-30 mM) sodium phosphate; 70-150 mM (e.g., 80-120 mM) methionine (e.g., L-methionine); and 1-10% (e.g., 4-6%) w / v sucrose or trehalose. The pH of the aqueous liquid composition may be 5-8 (e.g., 6-7).

[0035] In some embodiments, aqueous liquid compositions do not contain detectable amounts of mannitol, the most readily used crystalline excipients, as this may significantly increase the aggregation of human ASM during or after the lyophilization of the aqueous liquid compositions described herein.

[0036] In some embodiments, the aqueous liquid composition contains a surfactant in an amount of 0.004–0.008%, 0.005–0.007%, or 0.005% w / v. Exemplary surfactants include nonionic surfactants such as polysorbates (e.g., polysorbates 20 and 80) and poloxamers (e.g., poloxamer 188). In certain embodiments, the aqueous liquid composition contains 0.005% polysorbate 80. In some cases, the presence of a surfactant may help reduce the turbidity of the liquid composition.

[0037] In some embodiments, the aqueous liquid composition contains chelating agents such as EDTA and EGTA in concentrations of 0.05, 0.01, or 0.005 mM or less; in exemplary embodiments, the aqueous liquid composition does not contain a detectable amount of chelating agent. In some cases, the presence of chelating agents at concentrations exceeding, for example, 0.05 mM or 0.1 mM, may increase the aggregation of human ASM and reduce its stability, particularly after long storage periods such as 12–16 weeks, or under non-refrigerated conditions such as 25°C.

[0038] In some embodiments, the aqueous liquid composition may contain 0 to 50 ppm (e.g., 15 to 30 ppm) of zinc, which may be carried over from the manufacturing process or added externally.

[0039] In certain embodiments, the aqueous liquid composition comprises or essentially consists of 4 mg / mL olipudase alpha, 20 mM sodium phosphate, 100 mM methionine, and 5% (w / v) sucrose, and has a pH of 6.5. The term "essentially consists of" means that the composition does not contain other components in detectable amounts or contains only trace amounts of certain substances derived from the protein manufacturing process, and such substances do not affect the biological activity of the enzyme or harm human patients.

[0040] In some embodiments, the composition is an aqueous liquid composition comprising 1-20 mg / mL (e.g., 10 mg / mL) rhASM (e.g., olipidase alpha) and 10-50 mM (e.g., 20 mM) sodium phosphate. In certain embodiments, the aqueous liquid composition further comprises methionine (e.g., L-methionine) and sucrose or trehalose. In certain embodiments, the aqueous liquid composition further comprises 80-120 mM (e.g., 100 mM) methionine and 4-6% (e.g., 5%) (w / v) sucrose. In certain embodiments, the aqueous liquid composition has a pH of 6.5.

[0041] In some embodiments, the composition contains 1-50 mg / mL (e.g., 3.8, 18, or 49 mg / mL) of rhASM (e.g., olipidase alpha) and 10-50 mg / mL. The aqueous liquid composition contains M (e.g., 20 mM) sodium phosphate. In certain embodiments, the aqueous liquid composition further comprises 1-15% (e.g., 5%, 6%, 7%, or 8%) sucrose or trehalose. In certain embodiments, the aqueous liquid composition further comprises 80-120 mM (e.g., 100 mM) methionine. In certain embodiments, the aqueous liquid composition has a pH of 6.5. The composition may contain, for example, 3.8 mg / mL rhASM, 20 mM sodium phosphate, and 5% sucrose; 18 mg / mL rhASM, 20 mM sodium phosphate, and 5% sucrose; or 49 mg / mL rhASM, 20 mM phosphate, and 8% sucrose.

[0042] Aqueous liquid compositions can be prepared by mixing human ASM, produced by recombinant technology and subsequently purified from host cells, with the excipients described herein in water, and adjusting the resulting mixture to a desired pH. For example, human ASM and the desired excipient are added to or exchanged in a sodium phosphate buffer having a desired sodium phosphate concentration and pH.

[0043] In some embodiments, aqueous liquid compositions can be prepared by reconstituting the lyophilized compositions of the present invention, which are described in more detail below. Reconstitution can be carried out using a pharmaceutically acceptable liquid such as sterile water, saline solution (e.g., 0.9% sodium chloride), or phosphate-buffered saline.

[0044] Freeze-dried composition The present invention also provides freeze-dried compositions. Such compositions can be prepared by freeze-drying aqueous liquid compositions described herein. Freeze-dried compositions are suitable for long-term storage. Freeze-drying can be carried out according to methods known in the art. For example, the liquid composition may be cooled to a temperature below zero (Celsius) where freezing occurs (e.g., -5°C to -80°C), then placed in a low-pressure (partially vacuum) chamber to induce sublimation (primary drying); here, if necessary, the temperature of the composition may be raised in a second stage of drying (secondary drying) to further remove unwanted water molecules. In some embodiments, after the freeze-drying process is complete and before the container is sealed, an inert gas such as nitrogen is introduced into the container of the composition (e.g., a glass vial).

[0045] In some embodiments, the present invention provides powder compositions that can be prepared by, for example, spray-drying the aqueous liquid compositions described herein. Spray-dried compositions are suitable for long-term storage. Spray-drying can be carried out according to methods known in the art. For example, a liquid composition can be forcibly dispersed as small droplets of a controlled size in a high-temperature gas stream in a chamber through a sprayer or spray nozzle, thereby rapidly drying the liquid composition into a powder. The dried powder can then be collected at the bottom of the drying chamber. Other drying methods for preparing powder compositions are also contemplated.

[0046] The inventors unexpectedly discovered that sucrose (or trehalose) and methionine present in the amounts described herein provide excellent results during freeze-drying; the freeze-dried product maintains the stability of human ASM during storage, while also providing an elegant cake (elegant It forms cakes. The human ASM in the freeze-dried composition of the present invention can maintain its biological activity without aggregation for at least 4 months (e.g., at least 6 months, or at least 12 months) under refrigerated conditions (e.g., 0-10°C, 2-8°C, or 4°C).

[0064] To better understand the present invention, the following examples are provided. These examples are for illustrative purposes only and should not be construed as limiting the scope of the invention in any way. [Examples]

[0065] Recombinant human acid sphingomyelinase preparation This example describes a study that evaluated the stability of various aqueous liquid and lyophilized compositions of olipidase alpha.

[0066] material and method Turbidity of the solution The opacity of the solution was evaluated by spectroscopic turbidity assay. Optical densities in the 340–360 nm range were used to define a previously established range of opacity categories based on European Pharmacopoeia reference suspensions at specific NTU values. Analysis was performed using a SpectraMax Plus 384 microplate spectrophotometer (Molecular Devices, Sunnyvale, CA).

[0067] agglomeration Agglutination and dimerization analysis was performed by SEC. Each sample was mixed by five gentle pipette passes before loading into the HPLC vial. SEC analysis was performed on an 1100 / 1200 series HPLC (Agilent, Santa Clara, CA) equipped with a TSK Gel G3000SWXL (Tosoh Biosciences, Tokyo, Japan) analytical column and corresponding guard column. The mobile phase used was 20 mM sodium phosphate at pH 6, 0.5 mL min. -1 The solution was 200 mM sodium chloride, administered over 35 minutes at a flow rate of [specified flow rate]. Approximately 80 μg was injected into each sample three times. Detection was performed by UV absorbance at 280 nm.

[0068] The levels of olipudase alpha-related high molecular weight species (HMWS) were determined by SDS-PAGE under non-reducing conditions, followed by staining with Coomassie blue. An olipudase alpha reference standard was included in each gel. Olipudase alpha samples were mixed with sample buffer and loaded onto 4–20% Tris-Glycine gradient gels along with molecular weight markers. After electrophoresis at a 125V target for approximately 2 hours, the gels were stained with Coomassie blue and destained with methanol, acetic acid, and HPLC-grade water. Densitometry analysis was performed to provide quantitative results regarding the percentage of HMWS bands for all observed bands.

[0069] Enzyme activity The rhASM sample was diluted 2000:1 in a 1.2 mL library tube. This procedure measured the hydrolysis rate of 2-(N-hexadecanoylamino)-4-nitrophenylphosphorylcholine (HDA-PC) at 37°C catalyzed by rhASM. The released chromophore was measured by absorbance at 415 nm using a SpectraMax Plus 384 microplate spectrophotometer. One unit of rhASM activity is defined as the amount of enzyme that produces 1 μmol of 2-(N-hexadecanoylamino)-4-nitrophenol per minute from HDA-PC under the specified assay conditions.

[0070] Protein concentration The protein concentration of rhASM samples was determined by absorbance at 280 nm. Samples were diluted twice, 1:10 and 1:20, using the corresponding buffer. Absorbance at 280 nm was measured using a SpectraMax Plus 384 microplate spectrophotometer.

[0071] pH pH analysis of the samples was performed using a Thermo Electron Microprobe pH meter (Thermo Scientific, Beverly, MA). A Thermo Orion 8203BN PerHecT Ross semi-micro glass probe (Thermo Scientific) was used.

[0072] Differential scanning calorimeter Differential scanning calorimeter (DSC) analysis is performed using a CAP-VP-DSC microcalorimeter (M The analysis was performed using microCal-GE Healthcare (Northampton, MA). Samples were diluted to 0.4 mg / mL with the corresponding buffer. Samples were scanned at 15–100°C at a scanning rate of 200°C / hour. Data analysis was performed using Origin with DSC analysis add-on (MicroCal-GE Healthcare). It was conducted at 7.0 (OriginLab, Northampton, MA).

[0073] result Buffer and pH evaluation The effects of various buffer pH levels and buffer types on the stability of rhASM were evaluated. The assay was performed by incubating 4 mg / ml of olipidase alfa in 20 mM buffer at 30°C for 2 weeks and evaluating the physical and functional stability of the enzyme (Figures 1A-1C).

[0074] Significant physical and functional instability was observed in olipudase alfa below pH 6.0. Enzyme activity decreased sharply below pH 6.0 but remained relatively constant above pH 6.0 (Figure 1A). The tendency to aggregate was lowest between pH 5.5 and 6.5. A sharp increase in aggregation was observed below pH 5.5, and a gradual increase in aggregation was observed above pH 6.5 (Figure 1B). At comparable pH values, phosphate buffer was more stable than citrate / phosphate buffer. These stability trends were consistent with data obtained from samples stored at refrigerated temperatures. The gradual increase in aggregation rate observed above pH 6.5 was supported by DSC analysis, which indicated a decrease in thermal stability at higher pH levels in phosphate buffer (Figure 1C). Based on these data, sodium phosphate buffer at approximately pH 6.5 was identified as a suitable buffering system for rhASM formulations.

[0075] Next, the effect of ionic strength or buffer concentration on stability was investigated by varying the sodium phosphate concentration from 10 mM to 100 mM. As shown in Figures 2A and 2B, ionic strength at low buffer concentrations (10 mM, 20 mM, or 50 mM) had little effect on the enzymatic activity and physical stability of olipudase alpha. The stability of olipudase alpha at sodium phosphate, pH 6.5, was relatively consistent at buffer concentrations below 50 mM. However, increasing the sodium phosphate concentration to 100 mM resulted in a significant decrease in stability. Such concentrations led to a rapid increase in agglutination species and a corresponding decrease in activity (Figures 2A and 2B). The data at 30°C were consistent with data observed during storage of olipudase alpha under refrigerated conditions. A sodium phosphate concentration of 20 mM was selected as the buffer concentration, which, although low, ensured sufficient buffering capacity.

[0076] Evaluation of excipients The effects of various pharmaceutically acceptable excipients on the stability of olipidase alfa in liquid and lyophilized compositions were evaluated. The effects of known stabilizers acting via preferential exclusion mechanisms in liquid stability were investigated first (e.g., Timasheff, Proc Nat Acad Sci USA. 99: pp. 9721-9726 (2002); and Lee et al., J. Biol. Chem. 256: pp. 7193-7201 (1981)). Sucrose, trehalose, and propylene glycol were added to a basic formulation of 20 mM sodium phosphate, 0.005% PS80, pH 6.5, and their effects on the enzymatic activity and physical stability of 4 mg / mL olipidase alfa were evaluated. The data showed that the presence of any of these preferential exclusion stabilizers did not enhance the stability of olipidase alfa in liquid state at 5°C or 30°C (data not shown). While there was a loss of enzyme activity and physical stability under all conditions studied, sucrose appeared to be slightly preferable to trehalose and propylene glycol.

[0077] Next, the effects of sucrose and trehalose on the stability of olividase alpha during lyophilization were investigated. Mannitol was investigated as it is a commonly used filler in lyophilization (Figures 3A and 3B). Three polyols were included in the liquid composition at 5% w / v and then lyophilized. The data in Figure 3A show that the addition of mannitol reduced the enzymatic activity of olividase alpha after lyophilization. The data in Figure 3B show that the addition of mannitol resulted in a significant increase in protein aggregation after lyophilization. The increase in aggregation in the presence of sucrose and trehalose was minimal. As an antifreeze, sucrose was selected in the liquid composition at a concentration of 5% w / v, which could then be lyophilized.

[0078] The time-dependent stability of lyophilized olipudase alpha preparations in the presence of mannitol was also investigated. Olipudase alpha was lyophilized from a liquid composition containing 20 mM sodium phosphate buffer (pH 6.5), 0.005% PS80, and (i) 5% w / v mannitol, (ii) 5% w / v sucrose, or (iii) 3% mannitol and 2% sucrose. The data show that mannitol, when used alone, resulted in an immediate and continuous increase in protein aggregation during lyophilization, as well as when used in combination with sucrose for 6 months (Figures 3B and 4B). Enzyme activity at 6 months was also lower in the presence of mannitol than in the absence of mannitol (Figure 4B). Therefore, mannitol was considered an unsuitable bulking agent for lyophilized rhASM preparations.

[0079] Since mannitol was found to be detrimental to the stability of rhASM during lyophilization, methionine was evaluated as a potential bulking agent. Evaluation of the enzyme activity and physical stability of olipudase alpha during liquid storage in the presence of L-methionine revealed that the addition of 100 mM L-methionine neither improved nor adversely affected the liquid stability of olipudase alpha at 5°C. As shown in Figures 5A and 5B, lyophilized compositions prepared from liquid compositions containing 100 mM L-methionine yielded stable lyophilized olipudase alpha components. No changes in activity or aggregation were observed during storage at 5°C for 6 months. Furthermore, cakes obtained from lyophilized olipudase alpha in the presence of methionine and sucrose showed improved appearance compared to those lyophilized with sucrose alone.

[0080] The appropriate amount of methionine for lyophilization was identified by X-ray diffraction (XRD) of lyophilized olipudase alpha cakes from liquid compositions containing 20 mM sodium phosphate (pH 6.5), 5% w / v sucrose, and increasing amounts of L-methionine (data not shown). Samples without methionine were completely amorphous. Samples containing 33 mM methionine showed some evidence of crystallization, and samples containing 66 mM and 100 mM methionine showed further evidence of crystallization. Lyophilization of olipudase alpha at methionine levels below 100 mM (e.g., 10 mM and 33 mM) resulted in vials that appeared sunken and collapsed (shrunken). Therefore, 100 mM methionine was selected as the volume extender for the lyophilized rhASM formulation. [Examples]

[0081] Robustness of olipudase alpha composition To evaluate the robustness of compositions containing olipudase alpha, sucrose, and L-methionine, each of these components was set to five different levels (low, medium-low, medium (control), medium-high, and high) in 20 mM sodium phosphate buffer compared to a control (Table 1).

[0082] [Table 1]

[0083] A total of 26 liquid formulation variants were generated (Table 2). Formulations 2 and 7 represent the control formulation or center point. The remaining 24 formulation variants represent various conditions around the center point. All 26 variants were stored at 2–8°C (24 weeks or up to 12 months) and 25°C (16 weeks), and their stability was monitored.

[0084] [Table 2]

[0085] At the end of the test period, the following parameters would indicate the stability of the composition: (1) clear, colorless appearance; (2) pH 6.0-7.0; (3) aggregation ≤ 3.0%; (4) 3.5-4.5 mg / mL protein; (5) HMWS ≤ 15%; and (6) specific activity 11-42 U / mg. Figures 6-8 show 26 formulation variations after storage at 2-8°C for 24 weeks. The effects of different factors on % dimer, specific activity, and % HMWS are shown. The data show no significant differences between variants with respect to % dimer, specific activity, or % HMWS, and therefore all 24 variants were stable for 24 weeks at 2–8°C alongside two control formulations.

[0086] In some varieties, it was observed that there was no significant effect of various pH and component concentrations on % dimer and specific activity throughout the 36-week period. Figure 9 shows that all varieties exhibited similar aggregation at 36 weeks.

[0087] At an accelerated temperature of 25°C, the effect of excipients on stability over 16 weeks was minimal within the tested range. The most significant effects were observed in variants with different pH levels (Figure 10). Oripudase alpha was more stable at higher pH levels (6.8 to 7.0), while more aggregation and dimerization occurred at lower pH levels (below 6.5).

[0088] This study demonstrates that variant formulations are robust and stable within the selected component range at temperatures of 2–8°C.
