Conference call and webcast today at 4:30 p.m. ET

NEWARK, Calif., Aug. 10, 2020 (GLOBE NEWSWIRE) -- CymaBay Therapeutics, Inc. (NASDAQ: CBAY), a clinical-stage biopharmaceutical company focused on developing therapies for liver and other chronic diseases with high unmet need, today announced corporate updates and financial results for the second quarter and six months ended June 30, 2020.  

Specifically, in the second quarter and through early August 2020, CymaBay achieved significant progress in its ongoing efforts to review its strategic options, one of which included completing a scientific investigation and working with the FDA to lift the clinical holds on the seladelpar INDs in nonalcoholic steatohepatitis (NASH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC), the three liver diseases in which CymaBay had terminated clinical studies late last year.      

Sujal Shah, President and CEO of CymaBay, stated, “We are thrilled with the significant progress made to date in our efforts to conduct a review of strategic options, one of which was to pursue the reinstatement of our seladelpar program.  Specifically, in May, we convened a panel of expert liver pathologists and hepatologists that unanimously concluded after a thorough, independent investigation, that there was no clinical, biochemical, or histological evidence of seladelpar-induced liver injury for patients enrolled in our Phase 2b NASH study.  We discussed the panel’s findings and related information with the FDA and submitted complete responses to the agency, and in July, the FDA notified us that all clinical holds on seladelpar were lifted.  In addition to this favorable outcome, we evaluated and announced last week positive topline results from our ENHANCE study of seladelpar in PBC which, despite being terminated early, provided sufficient data which appear to support seladelpar’s efficacy and tolerability in this patient population.  After receiving notification from the FDA, and reviewing the latest clinical data from the ENHANCE study, we stopped our review of strategic options having decided to focus on reinstating the clinical development program for seladelpar in PBC and to continue to evaluate seladelpar for other indications. We have also been very successfully at minimizing our operating expenses through the first half of the year and expect our cash to fund our current operating plan into 2022.”

Recent Corporate Highlights

• In May 2020, a panel of eight of the world’s foremost expert liver pathologists and hepatologists, whose collective experience relevant to CymaBay’s investigation includes drug-induced liver injury, NASH and cholestatic liver diseases, completed a four-day independent review analyzing findings from CymaBay’s NASH Phase 2b study, and the results of independent pathologist’s reviews of the study biopsies, which included a blinded unpaired review and a paired review blinded to chronologic order of the biopsies. The panel unanimously supported lifting the clinical hold for seladelpar and re-initiation of clinical development pending approval by the FDA. In June 2020, CymaBay discussed the data and the panel’s conclusions with the FDA and submitted complete responses to the agency.  In July 2020, the FDA lifted clinical holds on seladelpar in all indications with open INDs (NASH, PBC and PSC). 
   
• In August 2020, CymaBay announced positive topline results from ENHANCE for seladelpar in patients with PBC.  Topline data for patients through 3 and 6 months demonstrated anti-cholestatic, anti-inflammatory, and anti-pruritic activity.  Notably, 78.2% of patients on seladelpar 10 mg versus 12.5% on placebo achieved the primary composite outcome after only 3 months (p<0.0001).  In addition, 27.3% of patients on seladelpar 10 mg versus zero on placebo experienced normalization of ALP by 3 months (p<0.0001).  Treatment with seladelpar 10 mg also resulted in a statistically significant improvement in pruritus (p<0.05) for patients with moderate-to-severe itch versus placebo.  Overall, seladelpar appeared to be safe and well-tolerated in this study.
   
• CymaBay intends to reinitiate the long-term study, a Phase 3 study and other NDA-enabling studies to confirm the potential of seladelpar to be a best-in-class treatment for patients with PBC and to further evaluate suitable strategies to advance seladelpar in other indications.
   
• CymaBay held $168.9 million in cash, cash equivalents and short-term investments as of June 30, 2020 and had no outstanding debt.  Cash and investments are deemed sufficient to fund CymaBay’s current operating plan into 2022. 
   
• Due to the ongoing effects of the global coronavirus pandemic, CymaBay continues to conduct its operations remotely for all employees, which has allowed business activities to continue as seamlessly as possible. To date, these developments have not had a significant impact on CymaBay’s financial condition or its ability to execute its business plan.  CymaBay will continue to closely monitor pandemic developments and their associated risks to the business, including plans to restart clinical development of seladelpar, and will continue to take actions available to mitigate them where possible. Further, all CymaBay’s actions will be guided by a commitment to taking all steps possible to ensure the health and safety of its employees as well as patients enrolled in its clinical studies.
  

Second Quarter and Six Months Ended June 30, 2020 Financial Results

• Research and development expenses for the three months ended June 30, 2020 were $7.9 million, compared to $21.1 million for the three months ended June 30, 2019.  Research and development expenses for the six months ended June 30, 2020 were $17.5 million, compared to $39.7 million for the six months ended June 30, 2019.  Research and development expense in the three and six months of 2020 was significantly lower than the corresponding periods in 2019 primarily due to declining clinical trial activities related to the Phase 3 PBC, Phase 2b NASH, and Phase 2 PSC clinical trials, and other studies, as efforts continued to shut down these studies which were early-terminated as a result of the FDA’s clinical holds that were placed on the seladelpar program in the fourth quarter of 2019.
   
• General and administrative expenses for the three months ended June 30, 2020 were $3.4 million, compared to $4.5 million for the three months ended June 30, 2019. General and administrative expenses for the six months ended June 30, 2020 were $7.7 million, compared to $10.2 million for the six months ended June 30, 2019. General and administrative expenses in the three and six months of 2020 were lower than the corresponding periods in 2019 due to lower employee compensation and other administrative expenses incurred as a result of a December 2019 reduction-in-force and restructuring effort that was undertaken to reduce costs in response to the FDA’s clinical holds on the seladelpar program.
   
• Net loss for the three months ended June 30, 2020 was $10.7 million, or ($0.16) per diluted share, compared to a net loss of $24.0 million, or ($0.35) per diluted share in the three months ended June 30, 2019. Net loss for the six months ended June 30, 2020 was $23.8 million, or ($0.35) per diluted share, compared to a net loss of $47.1 million, or ($0.72) per diluted share in the six months ended June 30, 2019.  Net loss was lower in the three and six months of 2020 compared to the corresponding periods in 2019 primarily due to a decrease in operating expenses, including clinical trial and labor related expenses, as a result of the early-termination of our seladelpar studies and our cost reduction efforts undertaken in response to the FDA’s clinical holds that were placed on the seladelpar program in the fourth quarter of 2019.
