Oral presentation will feature clinical data for seladelpar in primary biliary cholangitis (PBC) patients with cirrhosis

NEWARK, Calif., March 27, 2019 (GLOBE NEWSWIRE) -- CymaBay Therapeutics, Inc. (NASDAQ:CBAY), today announced that multiple seladelpar presentations will be delivered during The International Liver CongressTM of the European Association for the Study of Liver (EASL) in Vienna, Austria from April 10th – 14th. Seladelpar is a potent and selective peroxisome proliferator-activated receptor delta (PPARδ) agonist currently in development for PBC and nonalcoholic steatohepatitis (NASH).

The oral presentation titled “Seladelpar for the treatment of primary biliary cholangitis: experience with 25 cirrhotic patients”1 will be delivered by Dr. Marlyn Mayo, MD, Associate Professor and Liver Disease Specialist, University of Texas Southwestern Medical Center. This presentation will highlight the efficacy and safety of seladelpar in a subset of PBC patients with cirrhosis from an ongoing long-term Phase 2 study. After 52 weeks of treatment, the mean percent changes in alkaline phosphatase (AP) from baseline were -36% and -43% in the 5/10 mg (dose escalation) and 10 mg groups respectively. In addition, the safety and tolerability profiles of cirrhotic and noncirrhotic patients were similar. These data support that seladelpar maintained its anti-cholestatic effect over 52 weeks and appeared safe and well tolerated in PBC patients with cirrhosis.

“These results are very encouraging and support the further investigation of seladelpar in cirrhotic PBC patients. This is particularly important given the high unmet need that exists within this patient population who are at a greater risk of clinical decompensation,” said Dr. Marlyn Mayo, MD.

A second clinical presentation2 demonstrates that single dose oral administration of seladelpar appeared well tolerated and safe in subjects with varying degrees of hepatic impairment (Child-Pugh A-C) and provided important information on seladelpar pharmacokinetic exposure in this challenging population. A third presentation3 using the validated GLOBE score to model PBC clinical progression suggested that seladelpar treatment was associated with a long-term improvement in disease progression.

In addition, a preclinical presentation4 highlights that seladelpar demonstrates substantial anti-fibrotic and anti-steatotic activity in an obese mouse model of NASH.

Dr. Pol Boudes, Chief Medical Officer of CymaBay Therapeutics, commented, “We are excited to share additional data that further demonstrates that seladelpar retains efficacy and was well tolerated in PBC patients with compensated cirrhosis through 52 weeks. We believe these latest results from our Phase 2 program further de-risk the seladelpar ENHANCE Phase 3 global registration study that is currently recruiting and enrolling patients. We once again want to thank all the patients participating in our clinical studies, as well as their families, their physicians and the clinical research team members that tirelessly support them.”

About PBC
Primary biliary cholangitis (PBC) is a serious and potentially life-threatening autoimmune disease of the liver characterized by impaired bile flow (cholestasis) and accumulation of toxic bile acids. There is an accompanying inflammation and destruction of the intrahepatic bile ducts, which can progress to fibrosis, cirrhosis and liver failure. Other clinical symptoms of PBC include fatigue and pruritus, which can be quite disabling in some patients. PBC is primarily a disease of women: 1 in 1000 women over the age of 40 lives with PBC.

About NASH
Nonalcoholic steatohepatitis involves the development of a fatty liver that, in patients at risk, triggers inflammation and hepatocellular injury with or without liver fibrosis. The prevalence of nonalcoholic fatty liver disease is increasing, with estimates ranging from 20% to 40% of adults in countries adopting a western diet.  Ten to 20% of patients with fatty liver disease progress to nonalcoholic steatohepatitis. Patients with nonalcoholic steatohepatitis are at increased risk of cirrhosis and hepatocellular carcinoma, and nonalcoholic steatohepatitis is projected in the coming years to be the leading reason for liver transplant. Further, most patients with nonalcoholic steatohepatitis have coexisting obesity, insulin resistance with or without type 2 diabetes, hypertension, and dyslipidemia manifested by high serum cholesterol and triglycerides levels.

About Seladelpar
Seladelpar is a potent, selective, orally active PPARδ agonist that is in development for the treatment of the liver diseases PBC and NASH. For PBC, seladelpar has received an orphan designation from the US Food and Drug Administration (FDA) and the European Medicine Agency (EMA). Seladelpar also received Breakthrough Therapy Designation from the FDA and PRIority MEdicine status from the EMA for PBC.

About CymaBay
CymaBay Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on developing therapies for liver and other chronic diseases with high unmet medical need. CymaBay’s lead development candidate, seladelpar, is a potent, selective and orally active PPARδ agonist currently in development for the treatment of patients with primary biliary cholangitis (PBC), an autoimmune liver disease, and with nonalcoholic steatohepatitis (NASH). Two Phase 2 studies of seladelpar established proof-of-concept in PBC. CymaBay is currently enrolling patients in a global, Phase 3 registration study of seladelpar for PBC. This study is a 52-week, placEbo-coNtrolled, randomized, pHAse 3 study to evaluate the safety aNd effiCacy of sEladelpar (ENHANCE) in patients with PBC. CymaBay is also conducting a Phase 2b proof-of-concept study of seladelpar in patients with NASH.
