FIELD OF THE INVENTION

[001] The invention relates to pharmaceutical compositions, and more specifically to pharmaceutical compositions comprising at least one fatty acid-bile acid conjugate and at least one thyroid hormone receptor agonist or thyroid hormone mimetic or pharmaceutically acceptable salts thereof, and use of such compositions in methods of treating, stabilizing or lessening the severity or progression of a liver disease including fibrosis, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and comorbidities associated with a liver disease.

BACKGROUND OF THE INVENTION

[002] Fatty liver is one of the most common liver diseases known today. It occurs due to excessive accumulation of fat in the liver. It is demonstrated histologically by the presence of variable amounts of micro and/or macro vesicular fat droplets in the liver tissue. Fatty liver can be caused by drugs, chemicals, diseases, bacteria, etc. but the main cause is excessive dietary intake leading to (mainly truncal) obesity and insulin resistance. Due to the increasing prevalence of obesity in affluent societies the prevalence of fatty liver is rising. Fatty liver may progress to steatohepatitis and cirrhosis with the attendant morbidity and mortality. The best treatment for diet-induced fatty liver is sustained weight loss. However, it is well known that this is rarely achieved.

[003] The term nonalcoholic fatty liver disease (NAFLD) describes a spectrum of liver diseases ranging from simple fatty liver (steatosis) to nonalcoholic steatohepatitis (NASH) with progressive fibrosis and liver failure. NAFLDs exhibit the histological features of alcohol- induced liver disease in patients who do not consume significant amounts of alcohol. In NASH, the fat accumulation is associated with varying degrees of inflammation and fibrosis. All the stages of NAFLD have in common the accumulation of fat in the liver cells.

[004] Nonalcoholic steatohepatitis (NASH) is the advanced form of nonalcoholic fatty liver disease (NAFLD) which sets the stage for further liver damage. The mechanism for the progression of NASH involves multiple parallel“hits” or insults to the system, including steatosis, oxidative stress, mitochondrial dysfunction, apoptosis, inflammation, hepatic stellate cell activation and collagen production. [005] Fibrosis refers to the formation of excess fibrous connective tissue in an organ or tissue in a reparative or reactive process. This can be a reactive, benign, or pathological state. The deposition of connective tissue in the organ and/or tissue can obliterate the architecture and function of the underlying organ or tissue. Fibrosis is this pathological state of excess deposition of fibrous tissue, as well as the process of connective tissue deposition in healing.

[006] The burden of liver diseases, combined with a lack of any effective approved therapeutic interventions for NAFLDs such as NASH, represents an unmet medical need.

[007] Background art includes U.S. Publication No. US2018/0125862A; Farrell and Larter, Hepatology, 243:S99-S l l2 (2006); Palekar, et al., Liver int., 26(2): 151-6 (2006).

[008] Many patients do not respond to available treatments for fatty liver disease, and long term treatment is limited by toxicity and side effects. The development of safe and effective treatments for liver disease, including fibrosis, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and comorbidities associated with a liver disease, would be highly beneficial.

[0092] As used herein, the term“administering" includes any mode of administration, such as oral, subcutaneous, sublingual, transmucosal, parenteral, intravenous, intra-arterial, buccal, sublingual, topical, vaginal, rectal, ophthalmic, otic, nasal, inhaled, intramuscular, intraosseous, intrathecal, and transdermal, or a combination thereof. "Administering" can also include providing a different compound that when ingested or delivered as above will necessarily transform into the compound that is desired to be administered, this type of “different compound” is often being referred to as a“prodrug”. "Administering" can also include prescribing or filling a prescription for a dosage form comprising a particular compound. "Administering" can also include providing directions to carry out a method involving a particular compound or a dosage form comprising the compound or compounds.
