SEATTLE, Nov. 9, 2018 /PRNewswire/ -- Seal Rock Therapeutics, Inc., a discovery stage company developing best-in-class treatments for inflammatory and fibrotic diseases with no available therapies, today announced its lead compound, SRT-015, a differentiated inhibitor of apoptosis signal-regulating kinase 1 (ASK1) for nonalcoholic steatohepatitis (NASH), with promising preclinical proof-of-concept findings and recent worldwide patent application issued.
SRT-015 is a potent, liver-selective ASK1 inhibitor for NASH. The candidate was internally discovered and optimized by Seal Rock Therapeutics to improve upon and avoid dose-limiting liabilities demonstrated by other investigative approaches. Preclinical research of SRT-015 has demonstrated promising efficacy in the biopsy-proven, DIO-NASH Gubra therapeutic NASH mouse model. This includes statistically significant positive effects on both metabolic parameters and liver-specific pathology. In addition, SRT-015 significantly reduced hepatomegaly, liver fibrosis, steatosis and inflammation, all key drivers for NASH. These findings will be presented at the Keystone Symposia Integrated Pathways of Disease in NASH and NAFLD meeting, in Santa Fe, New Mexico, January 20–24, 2019.
"SRT-015 has a unique property that makes it particularly suitable for NASH: it is distributed to the liver where it is needed, but very little is present in the circulation or other tissues, which helps reduce risk of side effects and may allow for higher, more effective doses," said Neil McDonnell, Chief Executive Officer of Seal Rock Therapeutics. "Our preclinical findings are proving very robust, and we are pleased to be advancing with IND-enabling activities for SRT-015."
Additionally, Seal Rock Therapeutics announced the publication of an international PCT patent application for SRT-015 that includes ASK1 inhibitor compounds and uses thereof. The Patent Cooperation Treaty (PCT) is an international patent law treaty that includes 151 countries and covers all major pharmaceutical markets worldwide.
Seal Rock Therapeutics' founders include Neil McDonnell, PharmD; Artur Plonowski, MD, PhD, Chief Scientific Officer; and; Kathleen Elias, PhD, Vice President Research & Translational Medicine.
Dr. McDonnell previously served as CEO of Metacrine and senior vice president and therapeutic area leader for cardiovascular and metabolic diseases at Takeda. He has been involved in the development of diabetes drugs Nesina (alogliptin), Oseni (alogliptin + pioglitazone), and Kazano (alogliptin + metformin), and with Takeda's partner Orexigen, the obesity drug Contrave (bupropion and naltrexone).
Dr. Plonowski recently served as director of pharmacology at Akarna Therapeutics, Ltd, a NASH start-up that was acquired by Allergan in 2016 for $50 million and $1 billion in milestones. Prior to Akarna, he led the cardiovascular, renal and metabolic disease pharmacology group at Takeda Pharmaceuticals, and served for 10 years at Exelixis with scientific and leadership responsibilities in CV, metabolic, renal, oncology, and inflammation therapeutic areas.
Dr. Elias previously served as director of preclinical research at Takeda, and led efforts to develop small molecule, antibody and antibody drug conjugates for immune, metabolic and oncology indications. Prior to that, at Cytokinetics, she established and led the cell biology and pharmacology efforts to identity and develop a myosin activator therapeutic for heart failure, and at Genentech, identified therapeutics for endocrine and cardiac indications.
Additional members of the Seal Rock leadership team include Terry Porter, PhD, Senior Vice President, Business Development; and David Brown, PhD, Director, Chemistry.
Dr. Porter previously served as vice president of search & evaluation within global business development at Takeda Pharmaceuticals. Prior to that, he was managing director at the corporate advisory group AquaPartners. He was also a senior member of the worldwide business development group at GlaxoSmithKline. During this time, he headed oncology licensing, created and led the external science and technology group and co-led GSK's $450 million acquisition of Domantis.
Dr. Brown recently directed the medicinal chemistry team at Pathway Therapeutics, which led to the selective PI3Kdelta kinase inhibitor PWT143/MEI-401. Prior to that, he spent 12 years at Exelixis where his kinase work contributed to 5 clinical candidates in the areas of oncology and inflammation.
NASH is a form of non-alcoholic fatty liver disease (NAFLD) that affects one in four individuals worldwide, making it one of the most common chronic liver diseases. NAFLD is associated with metabolic conditions such as obesity, diabetes, and high cholesterol. NAFLD is typically characterized as either fatty liver or steatohepatitis. Fatty liver is generally non-progressive or progresses slowly compared to steatohepatitis. NASH, which is steatohepatitis not caused by alcohol, is characterized by inflammation of the liver, which progresses to fibrotic remodeling (scarring) in 30-50% of individuals, increasing the risk for cirrhosis, liver decompensation, and hepatocellular carcinoma (HCC, liver cancer). NASH is currently the second leading cause of liver transplantation overall, and the leading cause in women. Pharmacologic therapy is not yet available, but NASH is increasingly a focus of drug development efforts.
