CymaBay Therapeutics Announces Multiple Presentations at DDW 2019

May 8, 2019

NEWARK, Calif., May 08, 2019 (GLOBE NEWSWIRE) -- CymaBay Therapeutics, Inc. (NASDAQ: CBAY), today announced that multiple abstracts related to its seladelpar clinical development program for the treatment of primary biliary cholangitis (PBC) will be presented in poster sessions at Digestive Disease Week® (DDW) in San Diego, California from May 18 – 21, 2019. Seladelpar is a potent and selective peroxisome proliferator-activated receptor delta (PPARδ) agonist currently in development for PBC and nonalcoholic steatohepatitis (NASH).

The presentations will include new data1 from a qualitative study in collaboration with the PBCers Organization, the Canadian PBC Society, and Evidera highlighting itch (pruritus) as a significant symptom for PBC patients with multiple impacts. A second clinical presentation2 demonstrates that seladelpar maintained its anti-cholestatic effect over 52 weeks and appeared safe and well tolerated in PBC patients with cirrhosis. In addition, a third presentation3 highlights that single dose oral administration of seladelpar appears 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 difficult population.

“Itch (pruritus) is a common symptom in PBC patients and may be exacerbated by currently approved PBC treatment,” said Dr. Pol Boudes, Chief Medical Officer of CymaBay Therapeutics. “We are excited to collaborate with patient organizations and to share data that highlight the impact of itch (pruritus) on PBC patients. We hope these findings provide the medical community with a greater understanding of this debilitating symptom and highlight the most relevant tools to assess itch from the patient’s perspective. In addition, we will be presenting data from our Phase 2 PBC program, which we believe further de-risk the seladelpar ENHANCE Phase 3 global registration study that is currently recruiting and enrolling patients.”

Presentations at DDW 2019 include:

About PBCPrimary 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 SeladelparSeladelpar 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 ENHANCEENHANCE (NCT03602560) is a 52-week, placebo-controlled, randomized, Phase 3 study to evaluate the safety and efficacy of seladelpar. It will be conducted in more than 20 countries over five continents (North America, South America, Europe, Australasia and Asia). Approximately 240 PBC patients will be randomized to seladelpar 10 mg/day, seladelpar 5/10 mg/day (starting treatment at 5 mg with the possibility to escalate dose to 10 mg after 6 months), or placebo. Patients must experience an inadequate response to UDCA (defined as a serum alkaline phosphatase level ≥ 1.67 x the upper limit of normal after at least 12 months of treatment) or an intolerance to UDCA to be eligible for the study. Patients who are inadequate responders to UDCA will continue their treatment during the study, and UDCA will be provided free of charge. The primary outcome measure is the responder rate after 52 weeks. A responder is defined as a patient who achieves an alkaline phosphatase level < 1.67 x the upper limit of normal with at least a 15% decrease from baseline and has a normal level of total bilirubin. Additional key outcomes of efficacy will compare the rate of normalization of alkaline phosphatase at 52 weeks and the level of pruritus at 6-months assessed by a numerical rating scale recorded with an electronic diary. Additional information can be found at https://www.clinicaltrials.gov/ct2/show/NCT03602560?term=seladelpar&rank=2. After completing the study, patients will be offered to continue treatment in an open label extension study. Patients on placebo will be offered to start seladelpar in the extension study.
