[0003] Technical Field The present invention provides pharmaceutical compositions comprising an anti-human B7-H3 ("hB7-H3") antibody ("enoblituzumab") and a buffer for storage and administration. The present invention further provides containers and kits comprising the pharmaceutical compositions. The present invention further provides uses of the pharmaceutical compositions, containers, and kits containing enoblituzumab for the treatment of cancer, and in certain embodiments, for the treatment of cancers that express B7-H3. [Background technology]

[0004] B7-H3 (also known as "CD276") is expressed on antigen-presenting cells and binds to one or more unspecified receptors to mediate co-inhibition of T cells. Furthermore, B7-H3 acts as an inhibitor of NK cells and osteoblasts through interaction with one or more unknown receptors (Non-Patent Document 1). B7-H3 is expressed on a variety of cancer cells (e.g., neuroblastoma, gastric cancer, ovarian cancer, non-small cell lung cancer, etc.) (see, for example, Non-Patent Document 2). The role of B7-H3 in inhibiting the immune system and the increased expression of B7-H3 on human tumors suggest that this molecule may serve as a therapeutic target for the treatment of cancer. Anti-hB7-H3 antibodies and other molecules that modulate B7-H3 expression have been reported to be used to treat tumors and / or upregulate immune responses (see, for example, Patent Document 1).

In certain embodiments, the percentage (%) of each species (monomeric, HMW, and LMW) is calculated as a percentage (%) of the total protein. In one embodiment, the loss of monomeric purity of enoblituzumab in a pharmaceutical composition of the invention or in a dosing solution of the invention is about 15% or less, or about 10% or less, or about 5% or less, or about 4% or less, or about 3% or less, or about 2% or less, or about 1% or less over a designated period of time.

[0079] Another measure of stability is the stability of the charge heterogeneity profile of enobrituzumab in the pharmaceutical composition of the present invention or in the dosage solution of the present invention. The protein composition may contain various variants with different isoelectric points (pI). Such variants are called charge variants.

Method of Administration The pharmaceutical compositions of the present invention can be provided for the treatment, prevention, and amelioration of one or more symptoms associated with a disease, disorder, or infection by administering a therapeutically or prophylactically effective amount of enoblituzumab to a subject. In one embodiment, the pharmaceutical composition is substantially purified (i.e., substantially free of substances that limit the effectiveness of the composition or produce undesirable side effects) as determined by any suitable method. In another embodiment, the subject is an animal, including a mammal, such as a non-primate (e.g., bovine, equine, feline, canine, rodent, etc.) or a primate (e.g., monkey, such as cynomolgus monkey, human, etc.). In one embodiment, the subject is a human. The terms "subject" and "patient" are used interchangeably herein.

[0156] As used herein, a "therapeutically effective amount" of enoblituzumab of the pharmaceutical composition of the present disclosure when used to treat cancer is an amount that can slow the progression of cancer; reduce the number of cancer cells in a body fluid (e.g., blood, peripheral cells, or lymph), tissue, or organ (cytotoxic); maintain the number of cancer cells relatively constant (cytostatic); reduce tumor size, inhibit metastasis, inhibit tumor growth, and / or alleviate one or more of the symptoms of cancer. The therapeutically effective amount of enoblituzumab for use in formulating the pharmaceutical composition of the present disclosure is provided herein and / or can be determined, for example, by a medical professional, taking into account the type of cancer to be treated, the route of delivery, the age, weight, the severity of the subject's symptoms, and the subject's response pattern. As used herein, a "prophylactically effective amount" of enoblituzumab of the pharmaceutical composition of the present disclosure when used to prevent cancer is an amount that can prevent the occurrence or recurrence of cancer, or reduce the risk of the occurrence or recurrence of cancer. As used herein, treating cancer with the pharmaceutical composition, container, sealed package, kit, or method of the disclosure can include, for example, administering a therapeutically or prophylactically effective amount of enoblituzumab to a subject in need thereof.

[0157] Methods of administering the pharmaceutical compositions of the invention (i.e., enoblitutuzumab compositions) include, but are not limited to, parenteral administration (e.g., intravenously). In another embodiment, the pharmaceutical compositions of the invention (i.e., enoblitutuzumab compositions) are administered intravenously.

Such cancer antigens include, but are not limited to, 5T4, CD19, CD20, CD51, CD123, DR5, EGFR, EpCam, GD2, gpA33, HER2, PD-L1, ROR-1, TAG-72, and / or VEGFR2. Such antigens on immune cells include, but are not limited to, CTLA-4, LAG-3, and PD-1. Numerous antibodies and antibody-like molecules that bind to such cancer antigens or antigens on immune cells have been described, including, but not limited to, bevacizumab, cetuximab, enoblituzumab, flotetuzumab, margetuximab, ofatumumab, panitumumab, retifanlimab, rituximab, tebotelimab, trastuzumab, and the like.

[0158] In one embodiment, the amount of the pharmaceutical composition of the present invention (i.e., enoblitutuzumab composition) is determined using a weight-based dose of enoblitutuzumab to provide a subject with a therapeutically or prophylactically effective amount of enoblitutuzumab. The term "weight-based dose" as used herein refers to the individual amount of enoblitutuzumab administered per unit body weight of the patient, e.g., milligrams of enoblitutuzumab per kilogram of body weight of the subject (mg / kg body weight; abbreviated herein as "mg / kg"). The calculated dose is administered based on the subject's body weight at baseline. Typically, a significant change in body weight (e.g., at least plus or minus about 10% or more) from a baseline or established plateau body weight will prompt a recalculation of the dose. Single or multiple dosages may be administered.

[0159] In certain embodiments, enoblituzumab is administered to a subject in need thereof at a weight-based dose of about 6 mg / kg to about 15 mg / kg. In certain embodiments, enoblituzumab is administered to a subject in need thereof at a dose of about 6 mg / kg. In certain embodiments, enoblituzumab is administered to a subject in need thereof at a dose of about 10 mg / kg. In certain embodiments, enoblituzumab is administered to a subject in need thereof at a dose of about 15 mg / kg. With respect to weight-based doses, the term "about" is intended to refer to a range of ±10% of the stated dose, so that, for example, a dose of about 15 mg / kg would be 13.5 mg / kg, 16.5 mg / kg, or 13.5 mg / kg to 16.5 mg / kg.

[0160] A dose of the pharmaceutical composition of the invention (i.e., a dose of the enoblituzumab composition) can be administered to a subject at periodic intervals over a period of time (a course of treatment) sufficient to encompass at least 2 doses, at least 4 doses, at least 6 doses, at least 12 doses, or at least 24 doses, or more than 24 doses. Such administration of the pharmaceutical composition of the invention at periodic intervals over a period of time can be considered a "course of treatment." For example, a dosage can be administered once every 2 weeks ("Q2W"), once every 3 weeks ("Q3W"), once every 4 weeks ("Q4W"), or for a shorter or longer period of time. Such periodic administration can continue over a period of time, for example, from about 1 to about 52 weeks or for more than 52 weeks. Such a course of treatment can be divided into multiple increments of shorter intervals, for example, from 2 to 8 weeks, each of which is referred to herein as a "cycle," during which a set number of doses are administered. The dosage and / or frequency of administration may be the same or different during each cycle. Factors that may affect the dosing and timing required to effectively treat a subject include, for example, the severity of the subject's disease or disorder, the formulation, route of delivery, previous treatments, overall health, and / or age, and the presence of other diseases in the subject's body. Furthermore, treatment of a subject with a therapeutically effective amount of enoblituzumab can include a single treatment or a series of multiple treatments.

[0161] A "dosing regimen" is the administration of a dosage in which a given dose (or set of a plurality of such doses) is administered to a subject at a given frequency (or set of a plurality of such frequencies) with one or more predetermined periodicities. One dosing regimen of the invention comprises administering to a subject an enoblituzumab composition of the invention Q3W at a dose of about 3 mg / kg.

[0179] Having now generally described the invention, the same will be more readily understood by reference to the following examples, which are provided by way of illustration and are not intended to limit the invention, unless specifically stated.

[0180] Example 1 Development of pharmaceutical compositions containing enoblituzumab A stable antioxidant-free pharmaceutical composition comprising enoblitutuzumab (the "enoblitutuzumab formulation (DP) composition") was prepared as a liquid composition in a vial.

[0181] 1.1. Target Product Profile of Exemplary Enoblituzumab DP Compositions The target product profile of an exemplary enoblitutuzumab DP composition for a 250 mg or 425 mg vial is shown in Table 1 below.

[0182] [Table 1]

[0183] 1.2.Development of Enoblituzumab Drug Product (DP) Composition in 10 mM Acetate Enobrituzumab was initially formulated in 10 mM sodium phosphate, pH 6.1, 0.15 M NaCl and 0.05 mg / mL polysorbate 80 (PS80) (PBS-T), an acceptable formulation for many IgG1 antibodies. However, this condition resulted in a cloudy appearance when the enobrituzumab concentrate was refrigerated (2-8°C). To determine the effect of buffer, pH, excipients, and surfactants on the appearance of the formulation at 2-8°C, various protein concentrations (21.1 mg / mL to 39.4 mg / mL; shown in Table 2) were tested.

[0184] [Table 2]

[0185] The stability of enoblitutuzumab was compared between pH 5.1 (10 mM acetate buffer), pH 5.5 (10 mM acetate buffer), and pH 6.1 (10 mM phosphate buffer) in the presence of sucrose, sodium chloride, and polysorbate 80 (PS80). As shown in Table 2, lowering the pH and / or eliminating NaCl resulted in improved solubility properties of enoblitutuzumab. Furthermore, the flux rates during diafiltration at pH 5.1 and pH 6.1 showed significantly higher exchange efficiency for the pH 5.1 condition. The difference in diafiltration flux was consistent with the high solubility of enoblitutuzumab at pH 5.1. Further evaluation of the enoblitutuzumab concentrate after diafiltration in the presence of 10 mM sodium acetate at pH 5.1 established its suitability and molecular stability, with no observable change in monomer content. This formulation resulted in a clear antibody solution that could be easily filtered through a 0.2 μm membrane. To suppress the formation of subvisible particles that can be induced by agitation of the protein solution, 0.1 mg / mL of PS80 was added to the filtered enoblituzumab. Thus, in this example, 10 mM sodium acetate buffer at pH 5.1 (3 mM glacial acetic acid, 7 mM sodium acetate) and 0.1 mg / mL of PS80 were selected as the formulation buffer for further development.

[0186] 1.2.1. Evaluation of excipients Additionally, studies were conducted to identify excipients that could enhance the stability of enoblituzumab during storage (e.g., refrigerated or frozen). Enoblituzumab formulations at pH 5.1 containing 10 mM sodium acetate and 0.1 mg / mL PS-80 or pH 6.1 containing 10 mM sodium phosphate and 0.1 mg / mL PS-80 were further formulated by the addition of various excipients. One pH 6.1 formulation and seven other pH 5.1 formulations were prepared by adding combinations of sucrose, trehalose, sorbitol, arginine, lysine, glutamine, and NaCl to obtain mixtures with approximately equal osmolality. The enoblituzumab product stability of these formulations was evaluated at different storage temperatures, agitation stress at room temperature, and under freeze-thaw conditions. The eight enoblituzumab formulations tested are shown in Table 3, and the results of the study are provided below.

[0187] 1.2.2. Appearance evaluation First, the impact of selected excipients was evaluated by the appearance of the mixtures at 2-8°C. Solutions of enoblituzumab at pH 5.1 (acetate) or pH 6.1 (phosphate) became cloudy upon addition of 50 mM NaCl, 50 mM arginine, and 3% sucrose (see #5, #6 in Table 3). Other combinations of basic amino acids and 3-6% sucrose also remained hazy after mixing (see #3, #7, #8 in Table 3). A clear appearance was only achieved for the salt-free and arginine-free conditions (see #1, #2, #4 in Table 3).

[0188] [Table 3]

[0189] 1.2.3. Freeze-thaw research A freeze / thaw study was conducted to evaluate the effect of freezing at 80° C. and thawing at 25° C. for five cycles on the stability of enoblituzumab in seven exemplary formulations at pH 5.1 and one exemplary formulation at pH 6.1. Samples were analyzed initially and after one and five cycles for appearance and % aggregates by size-exclusion high performance liquid chromatography ("SE-HPLC"). Cryoprotection is similar for all formulations, except that those containing trehalose at pH 5.1 (#2) and those containing a combination of sucrose-lysine-NaCl at pH 5.1 (#7) showed slightly higher levels of aggregate formation after repeated freeze-thaw cycles. The 9% sucrose formulation was one of the two formulations with the highest compatibility in both appearance and freeze-thaw protection against aggregates among the eight formulations tested. The analytical results are summarized in Table 3.

[0190] The results show that significantly more subvisible particles are formed in the presence of sodium chloride after freeze / thaw. From the freeze / thaw studies, 9% (90 mg / mL) sucrose, 0.01% (0.1 mg / mL) PS80, 10 mM acetate, pH 5.1 was the most stable of the exemplary formulations for enoblituzumab.

[0191] 1.2.4. Aggregate studies Subsequently, accelerated stability studies were performed on enoblituzumab in glass vials at an elevated storage temperature of 37° C., as shown in Table 3. These conditions artificially increased the rate of aggregate formation and fragmentation, which may help differentiate potential stabilizing properties of added excipients. The arginine-sucrose combination (#3) and the four NaCl-containing formulations (#5, #6, #7, #8) appeared to destabilize enoblituzumab at elevated temperatures. Consistent improvements in appearance and stability were achieved with the addition of 9% sucrose (#1) versus other formulations of comparable osmolality. Thus, the aggregate studies also confirmed that the formulation composed of 10 mM sodium acetate, pH 5.1, containing 9% sucrose and 0.1 mg / mL PS80 was the most stable of the exemplary formulations with respect to enoblituzumab.

[0192] 1.3.Development of Enoblituzumab Drug Product (DP) Composition in 20 mM Acetate Studies were conducted to evaluate additional exemplary formulations, particularly antioxidant-free acetate formulations with enoblituzumab concentrations of 60 mg / mL or greater.

[0193] 1.3.1. pH shift analysis For this study, 20 mM sodium acetate buffers with pH between 3.7 and 5.0 were selected to evaluate pH shifts at a relatively high concentration of 60 mg / mL. Briefly, preformulated enoblituzumab was buffer exchanged into 20 mM formulation buffers with starting pHs of 3.7, 4.3, 4.5, 4.8, or 5.0 using dialysis cassettes. The resulting material was then concentrated to 60 mg / mL and sucrose (9% final) and PS80 (0.1% final) were added. pH, protein concentration (Solo-VPE), and percent high molecular weight species (%HMWS) by SE-HPLC were measured to evaluate the pH shift and aggregate levels of each formulation. The results are shown in Table 4.

[0194] [Table 4]

[0195] All formulations were observed to have a pH shift after buffer exchange into the target formulation. The pH shift is more pronounced the further away the pH of the starting buffer is from the molecular pI of 8.65. A shift of 0.8 pH units for a pH buffer starting at pH 3.7 was observed to result in a formulation with a pH of 4.5. When using a starting pH buffer of pH 5.0, the pH shift is reduced to 0.2, which results in a pH of 5.2 in the final formulation. Enoblituzumab >60 mg / mL formulated in 20 mM sodium acetate buffer at a relatively low pH of 4.5 had the lowest %HMWS of 1.7% compared to the formulation condition of pH 5.2, which had the highest %HMWS of 2.0%. The results for %HMWS indicate that there is a slight pH dependency in aggregate formation, with lower %HMWS observed in the lower pH formulations.

[0196] The pH shift effect is observed because enoblituzumab is a highly charged antibody with a pI of pH 8.65 as determined by imaged capillary isoelectric focusing (iCIEF). This study demonstrated that formulations of enoblituzumab, especially those at higher concentrations, are susceptible to pH shifts. The pH shift gradually decreased with increasing pH. Also, aggregate formation is partially pH dependent, as lower % aggregates were observed at lower pH conditions. Thus, the long-term stability of high-concentration enoblituzumab formulations is improved by using a higher buffer concentration (e.g., 20 mM), which can better achieve and maintain optimal pH.

[0197] 1.3.2. Accelerated and stressed thermal studies A short-term stability study was conducted to monitor the stability of enoblituzumab in additional exemplary enoblituzumab formulations under frozen (-60°C to -80°C), normal (2-8°C), accelerated (23-27°C), and stressed (38-42°C) storage conditions. Two 20 mM acetate-high concentration formulations containing 60 mg / mL enoblituzumab and one 10 mM acetate-low concentration formulation containing 25 mg / mL enoblituzumab were evaluated in this study. The formulation components, target protein concentrations, and pH are provided in Table 5. The enoblituzumab formulations were prepared and sterile filtered using 0.22 μM SterileFlip (PVDF) filters before being filled into sterile 2 mL USP Type 1 glass vials. Each vial was stoppered and capped under aseptic conditions. Vials were stored under frozen (-60°C to -80°C), normal (2-8°C), accelerated (23-27°C), and stressed (38-42°C) storage conditions. Enoblituzumab product quality was assessed using visual inspection, protein concentration (UV280nm, using Solo-VPE spectrophotometer), pH, osmolality, subvisible particulates (light obscuration, HIAC, selected time points), % high molecular weight species (%HMW) (SE-HPLC), and charge variant distribution (IE-HPLC). The stability study matrix including time points and storage conditions is summarized in Table 6.

[0198] [Table 5]

[0199] [Table 6]

[0200] The results of the stability studies are summarized in Tables 7-15. All three formulations were observed to be clear, light yellow, and essentially free of visible foreign matter and proteinaceous particles. Protein concentration, pH measured at T=0, and osmolality are shown in Table 7. Enobrituzumab at a concentration of 25 mg / mL formulated in 10 mM sodium acetate at pH 5 (10A50-25) showed no increase in %HMW species for all storage conditions up to 6 months. Enobrituzumab at a higher concentration of 60 mg / mL formulated in 20 mM sodium acetate at pH 4.8 (20A48-60) and 5.1 (20A51-60) showed no increase in %HMW species when stored under frozen (-70±10°C) and normal storage conditions (5±3°C) for up to 6 months (Tables 8 and 9). A small increase in %HMW species was observed for the high concentration (60 mg / mL) formulations under accelerated (25±2°C) and stressed (40±2°C) conditions (Tables 10 and 11). The high concentration formulation at pH 4.8 (20A48-60) showed slightly lower %HMW species formation compared to the high concentration formulation at pH 5.1 (20A51-50). The high concentration formulation at pH 4.8 showed an increase of 0.3% (from 1.1% to 1.4%) after 3 months at 25±2°C and an increase of 0.4% (from 1.1% to 1.5%) after 4 weeks at 40±2°C. In comparison, the high concentration formulation at pH 5.1 showed an increase of 0.4% (from 1.1% to 1.5%) and 0.6% (from 1.1% to 1.7%), respectively, under the same storage conditions.

[0201] The trend of charge variant distribution was similar for all three formulations during 6 months of storage. No significant changes in percent main charge peak (%MCP) were observed when stored up to 6 months at frozen (-70±10°C) and recommended (5±3°C) storage conditions (Tables 12 and 13). However, %MCP decreased from about 32% to about 24% after 3 months under 25±2°C storage conditions (Table 14) and from about 32% to about 16% after 4 weeks under stressed storage conditions at 40±2°C (Table 15). This decrease was accompanied by an increase in both acidic variants (AV) and basic variants (BV). The charge variant data does not indicate a pH or concentration dependency on degradation tendency.

[0211] In summary, this short-term stability study demonstrates the stability of all three exemplary enoblituzumab formulations at both frozen (-60°C to -80°C) and 2-8°C storage conditions, with no significant changes in product quality after 6 months of storage for both molecular weight distribution by SE-HPLC and charge variant distribution by IE-HPLC. The results of this study indicate that the high concentration formulation (60 mg / mL, 20 mM sodium acetate buffer, 9% sucrose, and 0.01% PS80) is slightly more stable when formulated at pH 4.8 compared to pH 5.1 based on %HMWS formation rate at accelerated (25±2°C) and stressed (40±2°C) conditions. Charge variant distribution demonstrated no concentration or pH dependent degradation at accelerated (25±2°C) and stressed (40±2°C) conditions.

[0212] 1.4. Overview of formulation development These formulation development studies demonstrate that enobrituzumab is stable under both frozen (-60°C to -80°C) and conventional (2°C to 8°C) storage conditions and that no significant changes in product quality occurred after 6 months of storage in terms of both molecular weight distribution by SE-HPLC and charge variant distribution by IE-HPLC when formulated in a 10 mM acetate formulation (25 mg / mL enobrituzumab, 10 mM sodium acetate, 9% sucrose, and 0.01% PS80, pH 5.1 ± 0.4) and a 20 mM acetate formulation (60 mg / mL, 20 mM sodium acetate, 9% sucrose, and 0.01% PS80, pH 4.8 ± 0.4).

[0213] These studies also demonstrate that, in contrast to other antibody compositions previously described, enoblituzumab can be formulated in about 10 mM to about 20 mM acetate, an acetate buffer containing sucrose and PS80 at a pH of 4.4 to 5.5, without the use of antioxidants (e.g., histidine, methionine). In particular, these studies support the use of 20 mM acetate, sucrose, and PS80 (e.g., 20 mM sodium acetate, 9% sucrose, and 0.01% PS80, pH 4.8±0.4) as a liquid formulation for a highly concentrated enoblituzumab DP composition. Further studies were also performed on highly concentrated enoblituzumab formulations, as provided in more detail below. Based on these formulation development studies, a first DP composition (25 mg / mL enoblituzumab, 10 mM sodium acetate, 9% sucrose, and 0.01% PS80, pH 5.1±0.4) was defined (referred to herein as "enoblituzumab DP1"), and a second DP composition (25 mg / mL enoblituzumab, 10 mM sodium acetate, 9% sucrose, and 0.01% PS80, pH 5.0±0.4) was defined (referred to herein as "enoblituzumab DP2").

[0214] 1.5. Methods of Supplying Enoblituzumab DP1 Compositions The components of selected enoblituzumab DP1 and DP2 compositions are shown below in Tables 16A and 16B, respectively. The enoblituzumab DP1 and DP2 compositions were supplied in 10 mL or 20 mL Type 1 borosilicate vials as shown in Tables 16A-16B: 250 mg / 10 mL (10 mL vial) or 425 mg / 17 mL (20 mL vial). Both the DP1 (Table 16A) and DP2 (Table 16B) compositions contain 25 mg / mL enoblituzumab, 10 mM sodium acetate, 9% sucrose, and 0.01% PS80, but with different ionic concentrations and slightly different target pH. The DP2 formulation ensures that the correct target pH of 5.0 is achieved and maintained stable over time.

[0215] [Table 16]

[0216] [Table 17]

[0217] Enoblituzumab DP1 and DP2 compositions were provided as sterile, buffered aqueous solutions in 10 mL (250 mg / vial) or 20 mL (425 mg / vial) Type I borosilicate glass vials conforming to USP and Ph.Eur., capped with 20 mm FluroTec® and B2-40 coated butyl rubber stoppers. The nominal content of each vial was 10 mL or 17 mL. Each vial was overfilled with 0.6 mL of liquid. The overfill was included to ensure sufficient volume to withdraw 10 mL (250 mg) and 17 mL (425 mg) of enoblituzumab for dose delivery. Target fill volumes, deliverable volumes, and vial / syringe hold-up volumes were determined by extractable volume testing. The enoblituzumab DP1 and DP2 compositions are clear to slightly opalescent, colorless to pale yellow or pale brown solutions. Some proteinaceous enoblituzumab particles may be present. The enoblituzumab DP compositions supplied as described in this section were used in the dosage compatibility studies described below, as well as the long-term and accelerated stability studies.

[0218] Example 2 IV Administration Compatibility Study of Enoblituzumab DP1 Composition The Enoblituzumab DP1 composition is available in single dose vials and is administered as an intravenous (IV) infusion after dilution in saline (0.9% Sodium Chloride Injection, USP). The dilution is calculated based on the amount to be administered, e.g., for weight-based dosing, the patient's weight and dose are used to calculate the amount. Compatibility has been tested to accommodate a wide range of doses from 0.01 mg / kg to 15 mg / kg.

[0219] 2.1. Overview of compatibility study with enoblituzumab DP1 To prepare for infusion, dilution of the enoblituzumab DP1 solution is performed in a saline-containing syringe or IV administration bag. The infusion solution is administered to the patient from a dose-prepared 0.9% sodium chloride IV bag or syringe using a commercially available IV pump and IV administration tubing set. As described in further detail below, stability and compatibility studies were performed with dose-prepared enoblituzumab dilution and storage at 25° C. for up to 24 hours, as well as IV infusion of enoblituzumab using unfiltered and filtered IV infusion sets over a 120 minute IV infusion period.

[0220] In the initial compatibility study, the enoblituzumab DP composition was diluted in a polypropylene syringe of the same composition as commonly used in clinical practice, or in a polyolefin IV bag of the same composition as commonly used in clinical practice, which were kept at 25° C. The dilution scheme for the test syringes followed a bracketing approach, with two doses (0.0450 mg / mL and 5.59 mg / mL) tested in a 20 mL polypropylene syringe with a small bore IV extension set, representing low and high dose concentrations. The dilution scheme for the test IV bags followed a bracketing approach, with multiple drug concentrations (0.0270 mg / mL, 0.135 mg / mL, and 5.59 mg / mL) tested in a polyolefin IV bag (50 mL and 250 mL size) with a standard IV administration set, representing high and low enoblituzumab dose concentrations. An overview of the bracketing approach and materials used are shown in Table 17.

[0221] [Table 18]

[0222] The structural integrity of enobrituzumab was maintained across all conditions and time points, as assessed by size-exclusion chromatography (SE-HPLC) and protein concentration recovery by UV spectrophotometry. These studies support the stability of enobrituzumab and its suitability for clinical administration when diluted in 0.9% sodium chloride in polypropylene syringes and polyolefin IV bags.

[0223] 2.2. Evaluation of the compatibility of the enoblitutuzumab DP1 composition for use with polypropylene syringes and small bore IV extension sets To evaluate the compatibility and stability of enoblituzumab in 20 mL polypropylene syringes, each of the two test concentrations of enoblituzumab was prepared in multiple syringes and incubated at 25°C.

[0224] Study design Enoblituzumab was diluted in saline to concentrations of 0.045 mg / mL and 5.59 mg / mL in 20 mL polypropylene syringes containing saline (Table 15). The syringes were then held at 25°C for 0, 4, 8, and 24 hours. Control samples not exposed to the polypropylene syringes were prepared in parallel and held at 2-8°C for 0, 4, 8, and 24 hours. Samples were collected from each syringe at the completion of dose preparation (T=0) and at each time point (4, 8, and 24 hours). For each time point, samples were removed from two syringes for analysis. Each syringe was used only for a single time point.

[0225] To evaluate the compatibility and stability of enoblituzumab during passage through a small bore IV extension set (used with a 20 mL syringe), two test concentrations of enoblituzumab were each prepared in four 20 mL syringes and incubated at 25°C for 4-6 hours. The contents of two of the syringes of each concentration were then removed as control samples for the IV extension set study. The remaining syringe was attached to a small bore IV extension set and a syringe pump was used to pass the contents through the extension set over a period of 120 minutes. The entire contents of one syringe were collected in a single container and analyzed. Two administration sets were analyzed for each concentration.

[0226] 2.2.2.Results The results of these studies demonstrate that no significant changes in protein recovery (IgG concentration) and appearance and size distribution (SE-HPLC) were observed for all groups tested following incubation in polypropylene syringes for up to 24 hours or passage through a small bore IV extension set. Recovery of enoblituzumab after incubation in 20 mL syringes for up to 24 hours or passage through an IV extension set was ≥ 97.2%, and the relative amount of IgG monomer (%monomer), aggregates (%HMW), or fragments, clipped antibody forms, and free light or heavy chains (%LMW) did not change significantly.

[0227] Representative results of an in-use compatibility study using polypropylene syringes and small bore IV extension sets, with saline as the dosing mixture, are shown in Tables 18 and 19. At each time point shown (0, 4, 8, and 24 hours), samples were removed from two syringes for analysis. Individual results for each of the two syringes are shown. Each syringe was only used for a single time point and analyzed for protein concentration (IgG % recovery) and structural integrity (by SE-HPLC).

[0230] Footnotes used in Tables 18 and 19: a IgG % recovery is calculated as the measured IgG concentration of the test article divided by the relevant reference value. The reference value for the control sample was the theoretical test concentration. The reference value for the T=0, T=4, T=8, and T=24 hour samples, or samples after IV plumbing, was the average measured value of the two control samples. b % monomer is calculated as the area of ​​the SE-HPLC monomer peak divided by the sum of all peaks. The % monomer of each test sample should be compared to a control sample at the same dose level. c % HMW - high molecular weight species including dimers and larger forms is calculated as the sum of all SE-HPLC peaks with an apparent molecular weight greater than the IgG monomer divided by the sum of all peaks. The % HMW of each sample is compared to a control sample at the same dose level. d LMW - low molecular weight; species with an apparent molecular weight less than the IgG monomer, including antibody fragments and unbound heavy or light chains. %LMW is calculated as the sum of all SE-HPLC peaks with an apparent molecular weight less than the IgG monomer divided by the sum of all peaks. The %LMW of each sample is compared to a control sample at the same dose level.

[0231] 2.3. Evaluating the compatibility of the enoblitutuzumab DP composition for use with polyolefin IV bags and standard IV administration sets To evaluate the compatibility and stability of the enoblituzumab DP1 compositions in polyolefin IV bags, 50 mL and 250 mL IV bags were prepared with low and high concentrations of the enoblituzumab DP1 compositions (Table 16A), respectively, and incubated at 25° C.

[0232] Study design The enoblitutumab DP1 composition was diluted to three concentrations (0.027 mg / mL, 0.135 mg / mL, and 5.59 mg / mL) in polyolefin IV bags containing saline (50 mL or 250 mL). Two test bags of each size and concentration were prepared on separate days (Study 1 and Study 2). The IV bags were then held at 25°C for 0, 4, 8, and 24 hours. Control samples were prepared in parallel and held at 2-8°C for 0, 4, 8, and 24 hours. At each time point, samples were removed from each IV bag for analysis.

[0233] The low concentration tested in the IV bag was based on an estimated low dose of 6.75 mg, which corresponds to a 45 kg clinical subject receiving a dose level of 0.15 mg / kg. The low concentrations tested were 0.0270 mg / mL in the 250 mL IV bag and 0.135 mg / mL in the 50 mL IV bag, respectively. The high concentration tested was based on an estimated high dose of 1800 mg, which corresponds to a 120 kg clinical subject receiving a dose level of 15 mg / kg. This dose was tested in a 250 mL IV bag to obtain a final concentration of 5.59 mg / mL (72.0 mL of the 25 mg / mL formulation was added to an IV bag containing 250 mL of saline). This concentration of 5.59 mg / mL was also tested as the upper limit concentration in the 50 mL IV bag.

[0234] Simulation of infusion through a standard IV tubing set was accomplished by attaching the tubing set to the IV bag after completion of a 4-6 hour incubation of the diluted enoblituzumab DP composition in the IV bag. At the start of the simulated infusion, a control sample (5 mL) was removed directly from the IV bag and the remaining infusion solution was passed through the tubing set for approximately 120 minutes. The contents of one IV bag were collected in a single sample container and analyzed. Each of the three concentrations was tested in duplicate on separate days (Study 1 and Study 2) using both unfiltered and filtered (sterile non-pyrogenic low protein binding polyethersulfone (PES) 0.2 μM in-line filter) IV administration sets.

[0235] 2.3.2.Results The results of these studies demonstrate that no significant changes in protein recovery (IgG concentration) and appearance and size distribution (SE-HPLC) were observed for all groups tested following incubation in saline in polyolefin IV bags for up to 24 hours or with passage through a standard IV extension set. Recovery of enoblituzumab after incubation in IV bags for up to 24 hours or passage through an IV extension set (unfiltered or filtered; 120 minutes) was ≥85.9% and ≥95.2%, respectively, and the relative amount of IgG monomer (%monomer), aggregates (%HMW), or fragments, clipped antibody forms, and free light or heavy chains (%LMW) did not change significantly.

[0236] Representative results of an in-use compatibility study using polyolefin IV bags and a standard IV extension set, with saline as the dosing mixture, are shown in Tables 20-22. At each time point indicated (0, 4, 8, and 24 hours), samples were removed from the IV bag for analysis. Within each study (Study 1 and Study 2), a single bag was prepared at each test concentration from which samples were removed for T=0, 4, 8, and 24 hours. Each sample was used only for a single time point and analyzed for protein concentration (IgG % recovery) and structural integrity (by SE-HPLC).

[0241] 2.3.3. Conclusions of the compatibility study of Enoblituzumab DP composition The enoblituzumab DP1 composition was shown to be compatible with saline solutions in 20 mL polypropylene syringes at concentrations ranging from 0.05 to 5.6 mg / mL and with saline solutions in polyolefin IV bags at concentrations ranging from 0.03 to 5.6 mg / mL. The enoblituzumab DP composition was also shown to be compatible with small bore IV extension sets and standard IV administration sets. These results support an enoblituzumab IV solution administration time of 120 minutes and storage of the IV bag preparation for up to 6 hours at room temperature and 24 hours at 2-8°C. These results further support the use of a 0.2 μM in-line PES filter for intravenous infusion of enoblituzumab.

[0242] Example 3 Long-term and accelerated stability studies of Enoblituzumab DP1 formulation Long-term and accelerated stability studies were conducted for enoblituzumab DP1 compositions in stoppered 10 mL or 20 mL glass vials. Stability was evaluated for enoblituzumab DP1 compositions stored at recommended conditions of 2-8°C for up to 48 months and at accelerated conditions of 23-27°C for up to 6 months.

[0243] Experimental Design A summary of the studies performed and the intervals typically evaluated at storage conditions of 2-8°C and 23-27°C are provided in Tables 23A and 23B, respectively. These studies were performed on 17 different lots of enoblituzumab DP1 composition. The majority of the studies were performed with vials in an upright position and with vials that were inverted at least once.

[0247] 3.2.Results The results of all testing on representative lots of enoblituzumab DP composition stored at 2-8° C. for 48 months and at 25° C. for 6 months are shown in Tables 24A-24B and 25, respectively. Further details regarding assay potency, purity, and protein stability (monomer and acidic and basic variants) are provided in the summary below.

[0248] [Table 26]

[0252] Stability data for all lots of the enoblituzumab DP1 composition investigated were within acceptable limits over 36-48 months at the intended long-term storage conditions of 2-8°C, with the exception of subvisible particulates. Subvisible particulates (P ≥ 2 μm and P ≥ 10 μm) increased in some lots, beginning around the 12th month of storage at 2-8°C. No further changes beyond analytical procedure variability were observed for other monitored parameters.

[0253] At accelerated storage conditions of 25±2°C, all lots investigated were within acceptable limits over 6 months. A slight reduction was observed in potency (B7-H3 binding) and purity by SE-HPLC. These changes in potency and purity under accelerated conditions were not unexpected for the protein and these results were well within acceptable limits. Homogeneity by IE-HPLC showed a moderate decrease in monomeric purity and a moderate increase in acidic variants in some lots, including the representative lot. The acidic variants contain mainly deamidated products. No changes beyond the variability of the analytical procedure were observed for any other parameters monitored, demonstrating the robust stability of the enoblituzumab DP1 composition.

[0254] 3.3. Conclusions regarding stability The above analysis of quantitative data from methods to demonstrate stability of multiple lots of the Enoblituzumab DP1 composition supports a shelf life of at least 24 months at recommended storage conditions of 2-8° C. The representative stability data presented in Tables 24A-24B and Table 25 also show that all other tests, both qualitative and semi-quantitative or non-quantitative, remained within acceptable limits over at least 24 months, supporting a shelf life of at least about 24 months, with an upper limit of at least about 36 to at least about 48 months.

[0255] Example 4 Stability studies on pharmaceutical compositions containing high concentrations of enoblituzumab Stable antioxidant-free pharmaceutical compositions were prepared containing high concentrations of enoblitutuzumab in liquid compositions. Enoblitutuzumab was formulated at 60 mg / mL or 120 mg / mL in 20 mM sodium acetate, 9% sucrose, and 0.01% PS80 at pH 4.8 (Ac60, Ac120). Additionally, enoblitutuzumab was formulated at 120 mg / mL in 20 mM histidine hydrochloride (histidine-HCl), 9% sucrose, and 0.01% PS80 at pH 5.4 (His120) to examine the effect of histidine on appearance and stability.

[0256] 4.1.Appearance evaluation The effect of high concentrations of enoblituzumab, acetate, and histidine-HCl buffer, and pH (4.8 and 5.4) was evaluated by mixture appearance at 2-8°C and 25°C. The results of these studies are shown in Tables 26 and 27. Enoblituzumab product quality was evaluated by visual inspection and subvisible particulates. A clear appearance was achieved after up to 3 months of storage at 2-8°C for enoblituzumab 60 mg / mL formulated in acetate buffer (Ac60) and enoblituzumab 120 mg / mL formulated in acetate buffer (Ac120) or 120 mg / mL formulated in histidine-HCl buffer (His120) (Table 26). The histidine-HCl formulations were more milky white than the acetate formulations after 1 month of storage at 25°C (Table 27). Visual observations in this study indicate that low pH acetate buffer is a good liquid formulation for enoblituzumab.

[0257] [Table 29]

[0258] [Table 30]

[0259] 4.2. Short-term stability study A short-term stability study was conducted to monitor the stability of enoblitutuzumab in high-concentration enoblitutuzumab formulations under normal (2-8°C), accelerated (25°C), and stressed (40±2°C) storage conditions. Enobrituzumab product quality was assessed using % high molecular weight species (%HMW) (SE-HPLC), and charge variant distribution (IE-HPLC). The results of this stability study are summarized in Tables 28-33. Molecular weight analysis for samples stored at 2-8°C (Table 28) showed that the % monomer decreased by approximately 0.6-0.9% over 3 months. A decrease of approximately 2.4-3.0% in the % monomer was observed at the accelerated storage condition at 25°C (Table 29). A larger decrease in the % monomer was observed at the stressed storage condition at 40°C (Table 30). The difference in percent monomer for samples stored at 2-8°C was not significant between the 60 mg / mL and 120 mg / mL acetate formulations at pH 4.8 and the 120 mg / mL histidine formulation at pH 5.4, as shown by SEC.

[0260] [Table 31]

[0261] [Table 32]

[0262] [Table 33]

[0263] The charge variant distribution for each formulation stored at 2-8°C, 25°C, and 40°C are shown in Tables 31, 32, and 33, respectively. Overall, the change in % main charge peak was not significant at normal storage conditions at 2-8°C. Under accelerated storage conditions at 25°C, the % main charge peak decreased by about 3.5%-4.5% at a concentration of 120 mg / mL. Under stressed storage conditions at 40°C, a larger decrease in % main charge peak was observed. No clear trends were observed for % acidic variant (AV) and % basic variant (BV) at any of the conditions tested (2-8°C, 25°C, and 40°C).

[0264] [Table 34]

[0265] [Table 35]

[0266] [Table 36]

[0267] In summary, these short-term stability studies demonstrate that enoblituzumab is stable at concentrations as high as 60 mg / mL and 120 mg / mL when formulated in 20 mM acetate buffer with 9% sucrose and 0.1% PS80 at pH 4.8, with no significant changes in product quality in terms of both molecular weight distribution by SE-HPLC and charge variant distribution by IE-HPLC after 3 months of storage under normal (2-8°C) and accelerated (25°C) storage conditions.

[0268] Example 5 Materials and Methods 5.1.A 280 Protein concentration by The protein concentration of enoblituzumab was determined by measuring the absorbance of the sample in a cuvette using a UV spectrophotometer or by a SoloVPE system (SoloVPE variable pathlength UV system from C Technologies, Inc.).

[0269] For the cuvette method, protein concentration was calculated using the following formula: Protein concentration (mg / mL) = [(corrected A 280 ) / ε]×DF where ε is the extinction coefficient and DF is the dilution factor of the sample preparation.

[0270] The SoloVPE system employs the Slope Spectroscopy method, which is based on the Beer-Lambert law and the slope obtained from linear regression of absorbance measurements at 280 nm performed at multiple path lengths. Protein concentration was calculated using the following Slope Spectroscopy equation: Protein concentration (mg / mL) = c = M / ε where c is the concentration, M is the slope of the regression line, and ε is the extinction coefficient calculated based on the amino acid sequence of enoblituzumab [1.43 (mg / mL)]. -1 cm -1 ].

[0271] 5.2. Invisible Particles by HIAC Liquid Particle Counting USP <788> and Ph.Eur.2.9.19 were used to detect, size, and count subvisible particulate matter in the formulation. An electronic liquid particle counting system with a light obscuration sensor is employed. Particles are counted in three size ranges, ≥ 2 μm (characterization information only), ≥ 10 μm, and ≥ 25 μm, using an electronic liquid particle counting system with a light obscuration sensor (HIAC). Ten vials (10 mL / vial) of the formulation are pooled for analysis.

[0272] 5.3.Appearance The appearance is USP <1> The solutions were visually evaluated in front of both white and black backgrounds under visible light meeting the minimum intensity requirements according to Ph.Eur. 2.2.2, and Ph.Eur. 2.9.20. Aliquots of samples were evaluated in clear glass vials. Attributes examined included solution color and solution clarity. The degree of coloration was determined using Ph.Eur. certified color standards. The degree of clarity was determined using Ph.Eur. certified reference suspension standards.

[0273] 5.4.pH Test The pH of the solution was measured according to the official method [USP <791> The pH was measured potentiometrically using a calibrated pH meter in accordance with [Russian Pharmacopoeia, Ph.Eur.2.2.3]. Prior to testing the samples, the pH meter was three-point calibrated using certified pH standards, starting with a pH 7 buffer standard, then a pH 4 buffer standard, and then a pH 10 buffer standard. Following calibration, the suitability of the system was checked using two certified pH buffers, pH 5 and pH 8.

[0274] 5.5. Monomer Purity by Size Exclusion High Performance Liquid Chromatography (SE-HPLC) Size-exclusion high performance liquid chromatography (SE-HPLC) was used as a measure of product purity and to measure impurities, especially IgG aggregates. The assay includes an enoblituzumab reference standard as a control for the identity of the IgG monomer peak and suitability of the system. Samples are injected onto the SE-HPLC column and eluted isocratically with sodium phosphate / sodium sulfate buffer. Eluted protein was detected using ultraviolet (UV) absorbance at 280 nm. The reportable result was product purity, calculated as the area percent of the product monomer peak (compared to all peaks minus excipient peaks). Also reported were the total percent of all species with an apparent molecular weight greater than the IgG monomer (referred to as high molecular weight species, or HMW), the percent of dimers (a potential component of the HMW species), and the total percent of all species with an apparent molecular weight less than the IgG monomer (referred to as low molecular weight species, or LMW).

[0275] 5.6. Charge Heterogeneity and Identity by IE-HPLC The charge heterogeneity and identity of enobrituzumab was assessed by ion-exchange high performance liquid chromatography (IE-HPLC). The assay includes an enobrituzumab reference standard as a control for identity and system suitability. Samples are injected onto a Thermo WCX-10 column or equivalent and eluted with a salt gradient at constant pH. Eluted protein was detected using ultraviolet (UV) absorbance at 280 nm. Reportable results were the main peak % area (percent of all detected peaks excluding buffer / excipient peaks), as well as the total % area of ​​all acidic variants (AV; or APG, i.e., acidic peak group: peaks eluting before the main peak) and the total % area of ​​all basic variants (BV; or BPG, i.e., basic peak group: peaks eluting after the main peak).

[0276] 5.7. Charge Heterogeneity and Identity by cIEF Alternatively, the charge heterogeneity and identity of enobrituzumab can be assessed by capillary isoelectric focusing (cIEF). For example, cIEF can be performed using an iCE3 system (ProteinSimple) with an Alcott 720NV autosampler. For such analysis, enobrituzumab reference standards and test article samples, containing carrier amphoteric and pI markers, are prepared and loaded into a capillary cartridge for analysis. Electrolyte tanks at each end of the capillary are filled with anolyte and catholyte. A voltage is applied and the sample is focused at the pI of the sample. A camera takes UV light absorption images of the entire capillary column at frequent regular intervals (e.g., every 30 seconds), allowing real-time monitoring of the focusing steps described above. The resulting separation pattern images are captured and analyzed with chromatography data system software. The electrophoretic profile of the test article is compared to that of the reference standard. Reportable results from this assay are the average main charge peak % area, the average acidic variant % area, and the average basic variant % area of ​​duplicate preparations.

[0277] To confirm identity where necessary, within a given sample set, the pI of the major peak of the test article should be within 0.5 pI units of the pI of the major peak of the enoblituzumab reference standard, and the profile of the test article should be qualitatively comparable to that of the reference standard.

[0278] 5.8 Purity by reduced and non-reduced CE-SDS and LDS Reduced and non-reduced sodium dodecyl sulfate capillary electrophoresis (CE-SDS) or sodium lauryl sulfate capillary electrophoresis (CE-LDS) provide quantitative information on the purity of the product and qualitative information on the nature of impurities, adducts, product fragments, and covalent species. Samples for the reduced method were denatured and reduced by heating in SDS sample buffer containing the reducing agent 2-mercaptoethanol (βME). Samples were then electrophoresed using a Sciex PA800 / PA800 Plus capillary electrophoresis system (formerly Beckman Coulter and AB Sciex). Test articles and reference standard samples are loaded into capillary cartridges and product purity is measured by UV detection (220 nm). The reportable result for the test article is % purity, defined as the sum of the relative percentages of the velocity-corrected peak areas corresponding to the heavy and light chains, which was reported to the nearest 0.1%. For the non-reduced method, samples were not reduced and the analysis was performed similarly to the reduced samples. The % purity was defined as the area under the peak of intact IgG molecules observed on the profile.

[0279] 5.9. Purity by non-reducing SDS-PAGE Non-reducing sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) provides quantitative information regarding product purity and qualitative information regarding the nature of impurities, adducts, product fragments, and covalently bound species. Samples were mixed with SDS-PAGE sample buffer without reducing agents. Samples were then electrophoresed using polyacrylamide gradient gels. Two concentrations of samples were loaded onto the gel for electrophoresis: a "low" load was used for quantification and a "high" load was used for qualitative comparison of the test article and reference standard. Each test article was analyzed individually on a single gel, and each gel also contained low and high loads of the enoblituzumab reference standard. After completion of electrophoresis, the gels were stained using Coomassie Blue dye and subsequently destained. The stained gels were scanned and analyzed using a digital imager and densitometry software. The area % of each visible band relative to the total area of ​​all visible bands was calculated. The reportable result was product purity, defined as the sum of the area percent of all bands (in the "low" load lane) that represented intact monomeric IgG. The area percent of a band was calculated relative to the total area of ​​all visible bands.

[0280] 5.10. Potency by B7-H3 Binding ELISA Potency was assessed using an indirect enzyme-linked immunosorbent assay (ELISA) to quantify the binding activity of enoblituzumab to B7-H3. Recombinant human B7-H3 was coated onto the solid phase (96-well assay plate). Enoblituzumab samples were allowed to bind to the immobilized B7-H3. Dilution series of the test article and enoblituzumab reference standard were tested in this manner to generate a dose-response curve. An alkaline phosphatase (AP)-conjugated anti-human kappa antibody was then added and allowed to bind to the enobrituzumab-B7-H3 complex. Quantitation of the bound AP-conjugated antibody was achieved by the addition of 4-methylumbelliferyl phosphate (4-MUP) substrate. Dephosphorylation of the added 4-MUP substrate by the AP-conjugated antibody yields the highly fluorescent and stable product 4-methylumbelliferone, which is measured using a fluorescent microplate reader. The level of fluorescent signal was proportional to the amount of enoblituzumab captured. The data was fitted to a four-parameter model to describe the fluorescent signal as a function of enoblituzumab concentration. The reportable results, i.e., the potency of the test article compared to the enoblituzumab reference standard, were calculated using the following formula: Relative potency = 100% × EC 50 B7‐H3 reference standard / EC 50 Test Article

[0281] 5.11. Potency and Identity by FcgRIIIa Binding ELISA The potency of the Fc domain was evaluated using an indirect competitive enzyme-linked immunosorbent assay (ELISA) that quantifies the binding activity of enoblituzumab to Fcγ reporter subtype IIIa (FcγRIIIa), also known as CD16a. Quantitation of binding of enoblituzumab test article Fc to FcγRIIIa was measured by its ability to compete with the binding of a biotin-labeled enoblituzumab competitor (enoblituzumab-Bt). To perform this assay, a solid phase (96-well assay plate) was coated with soluble recombinant human FcγRIIIa. A dilution series of enoblituzumab test article in a fixed concentration of enoblituzumab-Bt was allowed to bind to the immobilized FcγRIIIa. A dilution series of the test article and enoblituzumab reference standard were analyzed in this manner on the same assay plate to generate a dose-response curve. Detection of bound enobrituzumab-Bt was achieved by the addition of alkaline phosphatase conjugated to streptavidin (streptavidin-AP) followed by colorimetric AP substrate. The intensity of the color signal (absorbance) was measured using a microplate reader. The level of color signal was proportional to the amount of bound enobrituzumab-Bt. The data were fitted to a four-parameter model to describe the absorbance signal as a function of enobrituzumab concentration. The reportable result, i.e. the potency of the test article compared to the enobrituzumab reference standard, was calculated using the following formula: Relative potency = 100% × EC 50 Enoblituzumab Reference Standard / EC 50 Test Article

[0282] Osmolality Osmolality can be calculated from the USP <785> The measurements were performed using a freezing point depression osmometer using the method defined in [Ph.Eur.2.2.35].
