     In an embodiment, the setmelanotide; setmelanotide as sole active pharmaceutical ingredient formulated for injection; setmelanotide as the sole active ingredient; setmelanotide as the active pharmaceutical ingredient; setmelanotide as the active pharmaceutical ingredient for injection; or an MC4RA P  (e.g., BIM-22511, BIM-22287, BIM-22512, 001152C, 001543C, 001003C, 001574C, 001555C, 001554C, 001556C, 001358C, 001576C, 001364C, 001258C, or MC4R-11), as the sole active ingredient, as the sole active ingredient for injection, as the active pharmaceutical ingredient, or as the active pharmaceutical ingredient for injection, described herein, is optimized to allow for the neutral diacyl lipid and/or tocopherol and phospholipid components to be formulated in a wide range of proportions. In an embodiment, the pharmaceutical product has a greater proportion of neutral diacyl lipid and/or tocopherol to phospholipid than was previously achievable without risking phase separation and/or unacceptably high viscosities in the formulation. In an embodiment the ratio of neutral diacyl lipid and/or tocopherol to phospholipid is 1:1, or a ratio that is between 0.5 to 1.0, 0.7 to 1.0, or 1 to 0.5, or 1 to 0.7. 
     Methods described herein allow for more precise and accurate levels of alcohol in the preparations. The level of alcohol may affect release kinetics, e.g., burst profile. Levels that are too high may impact, e.g., negatively impact, release kinetics, e.g., burst profile. Control of the level of alcohol thus may allow for a more predictable and repeatable achievement of an optimized release profile. The level of alcohol may also affect pre-injection viscosity, with higher levels of alcohol resulting in lower viscosity. Thus, defined and repeatable levels of alcohol may allow for optimized performance. Described herein are methods that combine the addition of a known amount of alcohol with steps to minimize or control the level of loss by evaporation. In an embodiment, a method of making a pharmaceutical product described herein comprises the use of a controlled amount of alcohol to make the pharmaceutical product. In an embodiment, the pharmaceutical product is prepared so as to reduce or control evaporation, e.g., by the use of a closed vessel (thus reducing or controlling evaporation). The use of a closed vessel may allow for tight regulation of the amount of alcohol that is used to make the pharmaceutical product, and may improve the reproducibility of the pharmaceutical product. Preventing loss from evaporation is an important feature to reduce variability between batches of the pharmaceutical product, and between individual dosage units within a batch. Since the formulation may be used to deliver setmelanotide; setmelanotide as sole active pharmaceutical ingredient formulated for injection; or an MC4RA (e.g., BIM-22511, BIM-22287, BIM-22512, 001152C, 001543C, 001003C, 001574C, 001555C, 001554C, 001556C, 001358C, 001576C, 001364C, 001258C, or MC4R-11), as the sole active ingredient, as the sole active ingredient for injection, as the active pharmaceutical ingredient, or as the active pharmaceutical ingredient for injection in vivo, it is important that each batch of the pharmaceutical product contain a similar amount of the setmelanotide; setmelanotide as sole active pharmaceutical ingredient formulated for injection; or an MC4RA P , at a similar concentration. 
     Disclosed herein, inter alia, is a specified order in which components are added to the preparation.

     DETAILED DESCRIPTION 
     This disclosure provides, at least in part, a pharmaceutical product comprising: setmelanotide (also known as RM493); setmelanotide as sole active pharmaceutical ingredient formulated for injection; setmelanotide as the sole active ingredient; setmelanotide as the active pharmaceutical ingredient; setmelanotide as the active pharmaceutical ingredient for injection; or another pharmaceutical composition that has its primary mechanism of action at the MC4 receptor as an agonist (referred to as an MC4RA P ), e.g., BIM-22511 (also known as RM511), BIM-22287, BIM-22512, 001152C, 001543C, 001003C, 001574C, 001555C, 001554C, 001556C, 001358C, 001576C, 001364C, 001258C, or the MC4 receptor agonist disclosed as SEQ ID NO: 11 in WO 2008/147556 (referred to as MC4R-11), as the sole active ingredient, as the sole active ingredient for injection, as the active pharmaceutical ingredient, or as the active pharmaceutical ingredient for injection. 
     The pharmaceutical product of the disclosure generates a non-lamellar liquid crystalline phase following administration. The use of non-lamellar phase structures (such as liquid crystalline phases) in the delivery of bioactive agents is known to the field. Exemplary lipid depot systems are described, e.g., in WO 2005/117830, the entire contents of which are hereby incorporated by reference. 
     All % are specified by weight herein throughout, unless otherwise indicated. Furthermore, the % by weight indicated is the % of the total pharmaceutical product including all of the components indicated herein. The pharmaceutical product can optionally consist of essentially only the components indicated herein (including where appropriate additional optional components indicated herein below and in the attached claims) and in one aspect consist entirely of such components. 
     In an embodiment, a pharmaceutical product has an L 2  phase structure. In an embodiment, the pharmaceutical product forms a non-lamellar, e.g., liquid crystalline, phase following administration. 
     In an embodiment, a pharmaceutical product allows control of the peak concentration (C max ) of drug in the plasma to a level equal to or less than that tolerable to the subject, for example to avoid side-effects such as headache, alteration in blood pressure, heart rate, respiration rate, excessive perspiration, or other unwanted or undesirable effects while providing or achieving, an effective, e.g., therapeutically effective, level over the period of release. Generally, the average concentration during the period of release before the next dose is administered, C ave , falls within the therapeutic range. Control over the maximal (C max ) and minimum (C min ) concentrations over the defined dosage period, e.g. once weekly, or once monthly, is also important in order to achieve effective and safe treatment over time. In one embodiment, the initial burst is not the C max  of the release profile. 
     Whether or not the initial burst is also the C max , the C max /C ave  ratio is less than or equal to 10. In an embodiment, the C ave /C min  ratio is less than or equal to 10, e.g., less than or equal to 9, 8, 7, 6, 5, 4, 3, 2, or 1. In an embodiment, the C ave /C min  ratio is less than 3. C max  is defined as the peak or maximal plasma concentration observed during the period of release before the next dose is administered and C ave  is defined as the average plasma concentration during that period of release. C min  is correspondingly the minimal concentration during that period. C ave  can be calculated by calculating the drug present in the plasma as area under the curve (AUC) over the selected period of time, generally the entire period of release before the administration of the next dose, and dividing by that period of time.

     Component (c)—Alcohol 
     Component (c) as described herein comprises an alcohol. Since the pharmaceutical product is useful to generate a depot composition following administration (e.g., in vivo), typically upon contact with excess aqueous fluid, it is desirable that the alcohol be tolerable to the subject and be capable of mixing with the aqueous fluid, and/or diffusing or dissolving out of the formulation into the aqueous fluid. In an embodiment, component (c) comprises alcohols having at least moderate water solubility. 
     In an embodiment, the alcohol of component (c) comprises ethanol, propanol, isopropanol, or mixtures thereof. In an embodiment, component (c) comprises ethanol. 
     In an embodiment, addition or presence of less than 20 wt. % of the alcohol (e.g., less than 20, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3.5, 3, 2.5, 2, 1 wt. % or lesser) to a mixture comprising (a) and (b) gives large viscosity reductions, e.g., viscosity reductions of 30-70%, e.g., 30, 40, 50, 60 or 70% reduction, or more. In an embodiment, the addition or presence of 10 wt. % of alcohol to a mixture comprising (a) and (b) gives a viscosity reduction of 50%. 
     In an embodiment, the addition or presence of at least 10 wt. % alcohol to a mixture comprising (a) and (b) gives a viscosity reduction of at least 50% (e.g., at least 51, 52, 53, 54, 55, 56, 57, 58, 59, or 60% viscosity reduction). In an embodiment, the addition or presence of at least 2.5% wt. % alcohol to a mixture comprising (a), (b) and at least 10 wt. % alcohol, gives a further viscosity reduction at least 50% (e.g., at least 51, 52, 53, 54, 55, 56, 57, 58, 59, or 60% viscosity reduction). In an embodiment, the addition or presence of at least 3.5 wt. % alcohol to a mixture comprising (a), (b) and at least 12.5 wt. % alcohol, gives a further viscosity reduction at least 50% (e.g., at least 51, 52, 53, 54, 55, 56, 57, 58, 59, or 60% viscosity reduction). 
     The amount of component (c) in the pharmaceutical product can have a considerable effect upon several features. In particular, the viscosity and the rate (and duration) of release will alter with the alcohol level. The amount of alcohol will thus be at least sufficient to provide a low viscosity mixture which can easily and comfortably be injected by patient applying manual pressure to an injection device but will additionally be determined so as to provide the release rate. 
     Physical attributes such as viscosity, and reproducibility, e.g., batch-to-batch, or injection-to-injection reproducibility, are important when the pharmaceutical product is administered using mechanical or other powered devices, e.g., devices that assist injection by application of forces higher than a manually applied force, e.g., auto-injectors. The consistency of alcohol content, e.g., ethanol, within and between lots is important for reproducible performance, e.g., optimized pharmacokinetics, when the pharmaceutical product is administered using such devices, e.g., auto-injectors.

In an embodiment, an appropriate practical viscosity is that which can allow effective pressure to be applied, e.g., on a device, e.g., a syringe, e.g., a manual syringe (e.g., by manual pressure), or a spring-loaded syringe (e.g., an auto-injector) containing the pharmaceutical product. In an embodiment, a pharmaceutical product with appropriate practical viscosity allows pressure to be applied to a device, e.g., a syringe with an attached needle, e.g., a needle with a small diameter suitable for injection (e.g., a 27 Gauge needle), to administer, e.g., release, the pharmaceutical product.

     In an embodiment, component (c) comprises a single alcohol or a mixture of alcohols, e.g., alcohols which have a low viscosity. In an embodiment, formulations provided herein are of low viscosity and a primary role of a suitable solvent is to reduce this viscosity. This reduction will be a combination of the effect of the lower viscosity of the solvent and the effect of the molecular interactions between solvent and lipid composition. Disclosed herein is the observation that the oxygen-containing solvents of low viscosity described herein have advantageous and molecular interactions with the lipid parts of the composition, thereby providing a non-linear reduction in viscosity with the addition of a small volume of solvent. 
     In an embodiment, the viscosity of the low viscosity alcohol of component (c) (single solvent or mixture) is no more than 18 mPas at 20° C., e.g., no more than 15 mPas, 10 mPas, or 7 mPas.

     Method of Making-Controlling the Amount of Ethanol 
     It can be important to have a biologically active moiety, e.g., setmelanotide, within a pharmaceutical product that contains a predetermined or specified level of alcohol, e.g., a level that optimizes the viscosity of the pharmaceutical product prior to injections and the release profile after injection. Manufacturing methods can allow uncontrolled or unpredictable levels of loss of alcohol, e.g., by evaporation, during manufacture, and this loss may impede the ability to have controlled and repeatable levels of alcohol in the formulation. Methods of making a pharmaceutical product comprising a setmelanotide; setmelanotide as sole active pharmaceutical ingredient formulated for injection; setmelanotide as the sole active ingredient; setmelanotide as the active pharmaceutical ingredient; setmelanotide as the active pharmaceutical ingredient for injection; or an MC4RA P  (e.g., BIM-22511, BIM-22287, BIM-22512, 001152C, 001543C, 001003C, 001574C, 001555C, 001554C, 001556C, 001358C, 001576C, 001364C, 001258C, or MC4R-11), as the sole active ingredient, as the sole active ingredient for injection, as the active pharmaceutical ingredient, or as the active pharmaceutical ingredient for injection, having controlled and repeatable levels of alcohol, e.g., ethanol, are provided herein. The level of alcohol affects both pre-delivery viscosity and post-delivery release profile. Alcohol generally promotes lower viscosity but if too much is present it can affect release profiles in undesirable ways, e.g., by increasing C max . Thus, a controlled and repeatable level of alcohol is desirable. 
     Methods described herein control the level of alcohol in the completed pharmaceutical product, e.g., a pharmaceutical product comprising setmelanotide. Loss of added alcohol by evaporation can result in variability in the level of alcohol present in the pharmaceutical product. In an embodiment, the method comprises producing the pharmaceutical product in a closed system or vessel with the addition of a controlled amount of ethanol. Using a closed system or vessel may minimize loss of alcohol from evaporation. 
     In an embodiment, the disclosure provides a method of making the pharmaceutical product described herein with a controlled, or predetermined, amount of alcohol, e.g., ethanol. In an embodiment, the amount of alcohol, e.g., ethanol, in the pharmaceutical product is a predetermined amount, e.g., 10%. Methods of the disclosure comprise adding a measured amount of alcohol, e.g., ethanol, sometime referred to herein as the “addition amount” that, under the manufacturing conditions, results in a pharmaceutical product having a predetermined amount of alcohol, e.g., ethanol, after manufacture. Generally, the addition amount will be greater than the predetermined amount present after manufacturing, e.g., due to evaporation of alcohol during manufacturing. In an embodiment the addition amount is added as a single aliquot, and in other embodiments a plurality of aliquots are added to provide the addition amount. In embodiments, the method comprises additional measures that reduce alcohol evaporation, e.g., conducting one or more phases of the manufacturing process under conditions that reduce alcohol evaporation, e.g., controlling temperature or conducting a phase of the process in a closed vessel. 
     In an embodiment, the alcohol, e.g., ethanol, can be provided to the pharmaceutical product in one or more than one amounts or aliquots, e.g., in one, two, three or four amounts or aliquots. In an embodiment, a method of making the pharmaceutical product comprises, providing a first amount or aliquot of alcohol, e.g., ethanol, to setmelanotide; setmelanotide as sole active pharmaceutical ingredient formulated for injection; setmelanotide as the sole active ingredient; setmelanotide as the active pharmaceutical ingredient; setmelanotide as the active pharmaceutical ingredient for injection; or an MC4RA P  (e.g., BIM-22511, BIM-22287, BIM-22512, 001152C, 001543C, 001003C, 001574C, 001555C, 001554C, 001556C, 001358C, 001576C, 001364C, 001258C, or MC4R-11), as the sole active ingredient, as the sole active ingredient for injection, as the active pharmaceutical ingredient, or as the active pharmaceutical ingredient for injection, to dissolve or disperse the peptide.

     EXAMPLES 
     Example 1: Pharmacokinetics of Setmelanotide Formulations 
     Embodiments of sustained, e.g., extended, release of the pharmaceutical product, disclosed herein have desirable pharmacokinetic properties, e.g., a decreased C max  with no change or an increase in the Area Under the Curve (AUC). 
     Methods 
     Eleven different formulations of the pharmaceutical product were made and assessed for their in vivo pharmacokinetics properties in Cynomolgus monkeys. Formulations 5A-5D are described in Table 2. Formulations 3A and 4A are described in Table 3. Formulations 1A-1E are described in Table 4. 
     For each formulation of the pharmaceutical product, six male Cynomolgus monkeys were dosed with a single SC injection of either 0.5 mg/kg (formulations 1A-1C, 3A-4A and 5A-5C) or 1.5 mg/kg (formulations 1D-1E, and 5D). Between nine and eleven serial blood samples (approximately 0.8 mL/sample) were drawn from each subject over a period of 48 to 240 hours. Plasma (containing 1% HALT™ protease inhibitor) was harvested, frozen and shipped to Worldwide Clinical Trials, Austin, Tex., for analysis. Monkey plasma samples were analyzed for the peptide. The method used in this study was validated for a range of 5.00 to 2000 ng/mL based on the analysis of 0.100 mL of plasma. Quantitation was performed using a weighted 1/×2 linear least squares regression analysis generated from calibration standards. 
     Results 
       FIGS. 1A and 1B  illustrate the mean concentration data from SC injection of pharmaceutical product 1A-1C, 5A-5C, and 3A/4A, and an SC infusion administration from a previous study. The SC infusion of the peptide formulation (3A and 4A) demonstrated a low C max  and a large AUC, while SC injection of the same pharmaceutical product showed a higher C max  and much smaller AUC. 
       FIGS. 2A and 2B  illustrate the mean concentration data from pharmaceutical products 1D-1E, 5D, and the dose-normalized SC infusion data from a previous study. As in  FIGS. 2A and 2B , the SC infusion of the pharmaceutical product demonstrated a low C max  and a large AUC. Pharmaceutical product 1D, 1E and 5D had concentration-time profiles with an initial peak at 2 hours, a secondary peak or plateau between 48 and 96 hours, and then slowly decreasing between 96 and 240 hours. The data show that these pharmaceutical product dosages provide for an initial sustained burst of drug immediately after SC injection. The initial burst is followed by a period of continuous release and a subsequent 24 to 48 hour period when the pharmaceutical product release rate slightly increases.

     Example 2. Pharmacokinetics of Setmelanotide Formulations 
     In order to assess the pharmacokinetics of setmelanotide, a two part study was carried out comprising single dose administration (Part A) and multiple dose administration (Part B) with healthy obese subjects. 
     Part A was a rising-dose, placebo-controlled study including up to 3 sequential panels. For each panel, 10 normal obese subjects in good health between the ages of 21 and 54 were assigned to randomly-ordered treatments which included 8 active and 2 placebo treatments. Data acquired from Part A were used to determine the dose and dosing regimen for Part B. In Part B, 12 normal healthy obese patients were randomly assigned to receive either 6 active and 6 placebo treatments. Subjects received once weekly subcutaneous injection of the assigned formulation for 4 weeks. Patients in Part B were housed in the clinical unit for the 28 days. 
     Setmelanotide was formulated in a sterile liquid polar lipid phase consisting of soy phosphatidylcholine, glycerol dioleate, ethanol and citrate buffer. The concentration of each component in the formulation is summarized in Table 5. Without being bound by theory, the setmelanotide formulation behaves in a long-acting fashion, wherein when injected subcutaneously, aqueous body fluid is absorbed by the lipid phase to form a gel like depot consisting of liquid crystals formed in situ.

     Part a (Single-Dose Phase) 
     10 normal obese subjects enrolled for each dose level of Part A; 8 received active drug, and 2 received placebo. There were 3 dose levels used in the single dose phase which were administered according to the sequential, rising dose design. The single setmelanotide doses administered were in sequence: 2.5 mg, 10 mg, and 30 mg. Setmelanotide concentrations were analyzed and safety was assessed before the next higher dose level was started. The drug was administered subcutaneously on the morning of dosing. Blood samples were collected prior to dosing and at 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 30, and 36 hours post-dose (in the clinic), then at approximately 48, 60, 72, 96, 120, 168, 240, and 336 hours post-dose as outpatients. Based on the PK analysis of the first dose, additional blood samples were included for the 30 mg dose at 21 (480 hours) and 28 (648 hours) days post-dose. The actual times of blood collection were recorded. 
     Mean setmelanotide concentration for each sample at all three dose levels were quantified and are presented in  FIG. 3 . Generally, setmelanotide appeared in the earliest plasma sample time (0.5 hr) and slowly rose to maximum concentrations about 4 hours after dosing. Setmelanotide was measurable in plasma for 2 weeks or more after dosing. From the semi-logarithmic plot, the terminal phases of the 10 mg and 30 mg doses appear to be linear and parallel. However, the mean profile for the 2.5 mg dose indicates that setmelanotide concentrations in the plasms were considerably lower compared to the other two treatments, and concentrations decreased to below quantifiable levels from 24 to 96 hours after dosing. All values for the 2.5 mg dose were reported as below quantifiable by 96 hr (4 days after dosing). 
     Part B (Multiple-Dose Phase) 
     Twelve (12) obese subjects were enrolled in Part B; 6 received active drug, and 6 were given placebo. Based on results from Part A, setmelanotide 10 mg once weekly was selected as the dose for Part B. Subjects were housed in the clinical facility for the entire 4 weeks of study. Qualified subjects entered the clinical facility the evening before the first dose. Subjects assigned to active treatment received setmelanotide 10 mg subcutaneously in the morning on Day 1. Placebo subjects received the same volume of the placebo injection as the active treatment. Subjects were fasting from the evening before to 4 hours after dosing. Standard lowfat meals were served. Subjects were also dosed on Days 8, 15, and 22 with the treatment given on Day 1. 
     Blood samples were collected at a time before dosing and at 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16, 24, 30, 36, 48, 60, 72, 96, 120, 168, 240, and 336 hours during Week 1 and during Week 4. The actual sampling times were recorded. In addition, blood samples were collected at a time just before dosing for trough setmelanotide concentrations for evaluating the attainment of steady state. 
     Trough setmelanotide concentrations for the six subjects during the multiple-dose phase of Part B are shown in  FIG. 4 . By visual inspection, it appeared that steady state was attained during Week 4 after 4 weekly doses of the test formulation. 
     Conclusion 
     The PK objectives of this study were to evaluate the PK performance of an investigational setmelanotide injectable formulation designed for once weekly administration. The results of this study showed that for single dose administration, there was no early burst effect or dose dumping. Setmelanotide absorption started soon after injection with little to no lag-time. Mean C max  concentrations were 2.92, 11.5 and 34.1 ng/mL and median t max  values were 3.5, 4.0 and 6.0 hr for 2.5, 10 and 30 mg doses, respectively. Mean AUC ∞  values were 92.9, 1142 and 3474 hr*ng/mL, respectively. For the 2.5 mg dose, setmelanotide concentrations were measurable for 24 to 72 hours after dosing. In contrast, the profiles for the 10 mg and 30 mg doses were defined past 168 hours. The long half-life values for the 10 and 30 mg doses (mean values were 123 and 159 hr, respectively) indicate that absorption was still occurring during the week after dosing. Further, C max  was roughly proportional over the 2.5 to 30 mg dose range. AUC ∞  was proportional for the 10 mg and 30 mg doses. AUC ∞  for the 2.5 mg dose was less than proportional because plasma concentrations were undetectable after 24 to 72 hours. 
     For multiple dose administration, providing setmelanotide as a 10 mg dose once weekly for 4 weeks produced a mean C max  of 11.4 mg/mL at a median t max  of 4 hours. There was no lag in absorption, and setmelanotide concentration declined over the 1-week dosing interval to a mean concentration at 168 hours of 2.92 ng/mL. The mean AUC τ  for Week 4 was similar in magnitude to the mean AUC ∞  for Week 1, and the accumulation index for setmelanotide was 1.46. 
     Example 3. Stability Analysis of Setmelanotide Formulations 
     Components of exemplary setmelanotide formulations were varied in order to assess their impact on the stability of setmelanotide over time. In a first study, setmelanotide formulations were prepared as described in Example 2 with 30 mg/mL setmelanotide using different forms of GDO: 1) GDO of commercial purity; 2) GDO of commercial purity, which has been further purified to remove fatty acid compounds; and 3) synthetic GDO. The formulations were stored in 1 mL glass syringes equipped with staked stainless steel syringes and rubber plungers at 40° C. for up to three months. Samples were removed from each syringe over time and setmelanotide degradation was quantified by HPLC as shown in  FIG. 5 . As shown, formulations prepared with synthetic GDO exhibited a lower amount of setmelanotide degradation compacted with that in the other formulations tested. 
     The effect of EDTA concentration on setmelanotide degradation was also investigated in a second study. Syringes containing setmelanotide formulations with higher EDTA along with GDO of varying sources were prepared, and setmelanotide degradation was quantified by HPLC over time. The results of this study are depicted in  FIG. 6 , and indicate that higher concentrations of EDTA have a small effect on setmelanotide stability in the presence of either GDO of commercial purity or synthetic GDO. 
     In a third study, the effect of setmelanotide and EDTA concentrations were explored in the presence of synthetic GDO. There, formulations containing 15 mg/mL setmelanotide exhibited higher levels of degradation compared with 30 mg/mL formulations, and increasing EDTA concentration appeared to have a greater effect as setmelanotide concentration decreases; see  FIG. 7 .
