Attorney Docket No. SPM-007WO LIQUID PHARMACEUTICAL FORMULATIONS OF LOOP DIURETICS AND METHODS OF ADMINISTERING THE SAME CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to and the benefit of U.S. Provisional Patent Application No.63/376,157, filed on September 19, 2022, the content of which is incorporated herein in its entirety. BACKGROUND Loop diuretics, can be used in the treatment of hypertension, edema and related conditions, including congestive heart failure. For example, furosemide, is commonly used in the treatment and/or management of edema associated with congestive heart failure, hepatic failure and renal disease. H. Bundgaard, T. Norgaard, N. M. Nielsen, “Photodegradation and hydrolysis of furosemide and furosemide esters in aqueous solutions,” International Journal of Pharmaceutics 42, 217 (1988). Oral bioavailability, and therefore oral efficacy, of loop diuretics, such as furosemide, is often limited. Furosemide is commonly administered both parenterally and orally, although highly variable oral absorption is observed due to the combined effects of limited solubility and decreased stability at acidic pH. B. Devarakonda, D. P. Otto, A. Judefeind, R. A. Hill, M. M. de Villiers, “Effect of pH on the solubility and release of furosemide from polyamidoamine (PAMAM) dendrimer complexes,” International Journal of Pharmaceutics 345, 142 (Dec.10, 2007). Accordingly, furosemide typically is administered intravenously or intramuscularly for most patients with congestive heart failure or other forms of more advanced edema. Intravenous administration of a pharmaceutical drug, such as a loop diuretic, requires a trained healthcare professional for placement of the catheter and administration of the drug solution. In contrast, a pharmaceutical drug can be administered by subcutaneous injections or infusions by the patient or caregiver with the aid of auto-injection devices and/or wearable, on- body delivery infusion devices, for example, at home. Subcutaneous administration of loop diuretics by the patient or caregiver also can allow for more optimal therapeutic administration and total dose to provide a more appropriate pharmacokinetic and pharmacodynamic profile and patient outcome. For subcutaneous administration, discomfort and pain during administration should be minimized so as to avoid poor patient compliance with the treatment regimen. Factors that can contribute to pain and discomfort perceived by a patient upon, during, or after subcutaneous IPTS/124248410.1 Attorney Docket No. SPM-007WO administration include the injection volume, the pH of the formulation, and the osmoticity or tonicity of the formulation. Moreover, such a formulation should be stable in solution so that it readily is available for use and/or can be pre-loaded into a variety of drug delivery devices. Therefore, a need exists for improved pharmaceutical formulations containing a loop diuretic (e.g., bumetanide, furosemide, or torsemide) that are chemically and physically stable over their shelf-life, contain a sufficient concentration of the loop diuretic (e.g., a therapeutically effective amount in a suitable volume), and are at an appropriate pH and osmolality, for example, to permit subcutaneous administration of the loop diuretic. SUMMARY In one aspect, the invention provides liquid pharmaceutical formulations of a loop diuretic (e.g., bumetanide, furosemide, or torsemide), for example, a loop diuretic, and a pharmaceutically acceptable excipient. In various embodiments of the invention, the liquid pharmaceutical formulation comprises: (i) a loop diuretic such as furosemide, or a pharmaceutically acceptable salt thereof, in a therapeutically effective amount; (ii) an antioxidant; and (iii) a pharmaceutically acceptable buffer. In another aspect, the invention provides a unit liquid pharmaceutical formulation of a loop diuretic such as furosemide or a pharmaceutically acceptable salt thereof. In various embodiments of the invention, the unit liquid pharmaceutical formulation comprises: (i) from about 1 mg to about 250 mg of furosemide, or a pharmaceutically acceptable salt thereof; (ii) from about 0.1 % (w/w) to about 30 % (w/w) of one or more pharmaceutically acceptable excipients selected from the group consisting of ethanol, benzyl alcohol, glycerin, N- methyl-pyrrolidone (NMP), sodium chloride, sodium carbonate, mannitol, lactose, dextrose, a polyethylene glycol (PEG), propylene glycol, a polysorbate, a polyvinylpyrrolidone (PVP), a cyclodextrin or a derivative thereof, vitamin E or a derivative thereof, and any combination thereof; (iii) from about 0.05 % (w/w) to about 2 % (w/w) of an antioxidant selected from the group consisting of sodium metabisulfite, sodium bisulfite monothioglycerol, methionine, EDTA, and combinations thereof; and IPTS/124248410.1 Attorney Docket No. SPM-007WO (iv) from about 10 mM to about 500 mM of a pharmaceutically acceptable buffer selected from the group consisting of histidine, a citrate salt, sodium phosphate, potassium phosphate, tromethamine or a pharmaceutically acceptable salt thereof, and any combination thereof, wherein the pH of the liquid pharmaceutical formulation is from about 6.5 to about 8.5. Another aspect of the invention provides a method of treating congestion, edema, fluid overload, or hypertension in a patient in need thereof, the method comprising administering to the patient a liquid pharmaceutical formulation or a unit liquid pharmaceutical formulation described herein. Another aspect of the invention provides a kit for the treatment of congestion, edema, fluid overload, or hypertension comprising a liquid pharmaceutical formulation, or a unit liquid pharmaceutical formulation described herein and a delivery device (e.g., pump device, autoinjector, etc.), along with written instructions for use. DETAILED DESCRIPTION The invention provides liquid pharmaceutical formulations and unit liquid pharmaceutical formulations containing a loop diuretic (e.g., bumetanide, furosemide, or torsemide), medical kits containing the same, and methods of using the liquid pharmaceutical formulations and unit liquid pharmaceutical formulations to treat medical disorders e.g., congestion, edema, fluid overload, or hypertension in a patient in need thereof.

Such organisms are preferably mammals (e.g., murines, simians, equines, bovines, porcines, canines, felines, and the like), and more preferably humans (e.g., adult humans). As used herein, a “buffer” refers to an aqueous solution that is resistant to changes in pH. A buffer may include a “buffering agent” such as a weak acid and its salt, or a weak base and its salt, which assist in maintaining the stability of the pH. Examples of buffers used in pharmaceutical formulations include bicarbonate buffers, carbonate buffers, citrate buffers, IPTS/124248410.1 Attorney Docket No. SPM-007WO histidine buffers, phosphate buffers, tartrate buffers, tris(hydroxymethyl)aminomethane (or 2- amino-2-hydroxymethyl-propane-1,3-diol [(HOCH2)3CNH2]) buffers, and combinations thereof. Certain of these buffers are suitable for pharmaceutical formulations administered subcutaneously. Tris(hydroxymethyl)aminomethane or a tris(hydroxymethyl)aminomethane buffer can be referred to as “TRIS,” “Tris,” “Tris buffer,” “Trisamine,” “THAM,” “tromethamine,” and other names. In addition, many buffers and/or buffer systems can include Tris, or a pharmaceutically acceptable salt thereof, and can be used in the present teachings. For example, Tris-buffered saline (“TBS”), Tris-hydrochloride buffer (“Tris-HCl”), Tris base (pH 10.6), Tris/borate/ethylene diamine tetra-acetate (“EDTA”) buffer (“TBE”), and Tris/acetate/EDTA buffer (“TAE”). Tris base often is used with Tris-HCl to prepare Tris buffers at a desired pH. In addition, the present teachings can include Tris-related compounds, for example, compounds derived from Tris or structurally related to Tris, that can act as a buffer. As used herein, “tonicity” refers to the ionic strength or concentration of ions in a solution such as a pharmaceutical formulation. Tonicity often is measured in molarity (“M”). As used herein, an “isotonic solution,” an “isotonic formulation,” an “isotonic pharmaceutical formulation,” and a pharmaceutical formulation that is “isotonic” refers to a solution or formulation that has the same or similar concentration of ions as found in bodily fluids. As used herein, “physiological pH” refers to a pH of about 7.4. As used herein, “osmoticity” and “osmolality” refer to the osmotic pressure of a solution such as a pharmaceutical formulation. Osmoticity often is measured in osmolarity (“Osm/L” or “OsM”) or osmolality (“Osm/kg”), which can be used interchangeably herein. When measuring freezing point depression, the observed value is the osmolality of the solution. In contrast to tonicity, osmoticity accounts for un-ionized solutes in a solution such that when present, the osmolarity or osmolality of the solution will be higher than its tonicity. The osmolarity of a liquid pharmaceutical formulation described herein can be measured, for example, using a vapor pressure method. As used herein, “osmolarity adjustor” and “osmotic agent” refer to a pharmaceutically acceptable compound that may be added to a liquid pharmaceutical formulation described herein in order to modulate the osmolarity of the liquid pharmaceutical formulation. As used herein, “pharmaceutically acceptable” refers to a substance that is acceptable for use in pharmaceutical applications from a toxicological perspective and does not adversely interact with the active ingredient. Accordingly, pharmaceutically acceptable carriers are those that are compatible with the other ingredients in the formulation and are biologically acceptable. IPTS/124248410.1 Attorney Docket No. SPM-007WO In certain embodiments, supplementary active ingredients can also be incorporated into the pharmaceutical compositions. As used herein, “pharmaceutically acceptable excipient” refers to a substance that aids the administration of an active agent to and/or its absorption by a subject and can be included in the compositions and formulations of the present invention without causing a significant adverse toxicological effect on the patient. In certain embodiments, a pharmaceutically acceptable excipient described herein may also be used to improve the stability of a liquid pharmaceutical formulation or a unit liquid pharmaceutical formulation described herein. In certain embodiments, a pharmaceutically acceptable excipient described herein may also be used to improve the solubility of a loop diuretic in a liquid pharmaceutical formulation or a unit liquid pharmaceutical formulation described herein. Non-limiting examples of pharmaceutically acceptable excipients include liquid vehicles such as water, NaCl, normal saline solutions, buffers and buffering agents such as a phosphate buffered saline solution, components or compounds of emulsions (e.g., such as an oil/water or water/oil emulsions), lactated Ringer’s, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer’s solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxypropylmethylcellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary excipients such as lubricants, preservatives, stabilizers, solubilizing agents, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention. For examples of excipients and carriers, see Martin, Remington’s Pharmaceutical Sciences, 15th Ed., Mack Publ. Co., Easton, PA (1975). As used herein, the term “pharmaceutically acceptable carrier” refers to any of the standard pharmaceutical carriers, such as a buffer such as a phosphate buffered saline solution or a tromethamine buffered water solution, water (e.g., water for injection (WFI)), emulsions (e.g., such as an oil/water or water/oil emulsions), and various types of wetting agents. The compositions also can include stabilizers and preservatives. For examples of carriers, stabilizers and adjuvants, see Martin, Remington's Pharmaceutical Sciences, 15th Ed., Mack Publ. Co., Easton, PA [1975]. As used herein, the term “pharmaceutically acceptable salt” refers to any pharmaceutically acceptable salt (e.g., acid or base) of a compound of the present invention (e.g., a loop diuretic described herein) which, upon administration to a subject, is capable of providing a compound of this invention or an active metabolite or residue thereof. As is known to those of skill in the art, “salts” of the compounds of the present invention may be derived from inorganic IPTS/124248410.1 Attorney Docket No. SPM-007WO or organic acids and bases. Examples of acids include, but are not limited to, hydrochloric, hydrobromic, sulfuric, nitric, perchloric, fumaric, maleic, phosphoric, glycolic, lactic, salicylic, succinic, toluene-p-sulfonic, tartaric, acetic, citric, methanesulfonic, ethanesulfonic, formic, benzoic, malonic, naphthalene-2-sulfonic, benzenesulfonic acid, and the like. Other acids, such as oxalic, while not in themselves pharmaceutically acceptable, may be employed in the preparation of salts useful as intermediates in obtaining the compounds of the invention and their pharmaceutically acceptable acid addition salts. Examples of bases include, but are not limited to, alkali metal (e.g., sodium) hydroxides, alkaline earth metal (e.g., magnesium) hydroxides, ammonia, and compounds of formula NW ₄ ⁺ , wherein W is C _1-4 alkyl, and the like. Examples of salts include, but are not limited to: acetate, adipate, alginate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, citrate, camphorate, camphorsulfonate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, fumarate, glucoheptanoate, glycerophosphate, hemisulfate, heptanoate, hexanoate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethanesulfonate, lactate, maleate, methanesulfonate, 2- naphthalenesulfonate, nicotinate, oxalate, pamoate, pectinate, persulfate, phenylpropionate, picrate, pivalate, propionate, succinate, tartrate, thiocyanate, tosylate, undecanoate, and the like. Other examples of salts include anions of the compounds of the present invention compounded with a suitable cation such as Na ⁺ , NH4 ⁺ , and NW4 ⁺ (wherein W is a C1-4 alkyl group), and the like. It should be understood herein that, unless stated otherwise, all weights described herein correspond to the weight of a compound (e.g., furosemide, torsemide, bumetanide) in its free- acid/free-base form. As used herein, the term “effective amount” refers to the amount of a composition (e.g., a liquid pharmaceutical formulation or a compound disclosed herein) sufficient to effect beneficial or desired results. An effective amount can be administered in one or more administrations, applications or dosages and is not intended to be limited to a particular formulation or administration route. As used herein, the terms “treat,” “treating,” and “treatment” include any effect, e.g., lessening, reducing, modulating, ameliorating or eliminating, that results in the improvement of the condition, disease, disorder, and the like, or ameliorating a symptom thereof. The phrase "therapeutically-effective amount" as used herein means that amount of a composition (e.g., a liquid pharmaceutical formulation or a compound disclosed herein) which is effective for producing some desired therapeutic effect in a subject. IPTS/124248410.1 Attorney Docket No. SPM-007WO As used herein, the term “congestion” (in heart failure) is the presence of signs and symptoms of extracellular fluid accumulation that results in increased cardiac filling pressures leading to reduced cardiac output. This reduced cardiac output is further exacerbated by neurohormonal activation leading to increased renal sodium and water avidity resulting in an increased plasma volume. As used herein, “fluid overload,” “volume overload” and “hypervolemia”, may describe a medical condition where there is too much fluid in the blood. Excess fluid, primarily salt and water, may build up throughout the body resulting in weight gain. Throughout the description, where compositions and kits are described as having, including, or comprising specific components, or where processes and methods are described as having, including, or comprising specific steps, it is contemplated that, additionally, there are compositions and kits of the present invention that consist essentially of, or consist of, the recited components, and that there are processes and methods according to the present invention that consist essentially of, or consist of, the recited processing steps. As a general matter, compositions specifying a percentage are by weight unless otherwise specified. Further, if a variable is not accompanied by a definition, then the previous definition of the variable controls.
