NEWARK, Calif., Nov. 05, 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 third quarter and nine months ended September 30, 2020.
In the third quarter and through early November 2020, CymaBay made significant progress in restarting the development program for seladelpar in primary biliary cholangitis (PBC). Start-up is well underway for RESPONSE, a global phase 3 registration study evaluating seladelpar in patients with PBC and is poised for first patient dosed in the first quarter of next year. Results from the ENHANCE phase 3 study will be featured on November 16 in the late-breaking session of The Liver Meeting® 2020 sponsored by the American Association for the Study of Liver Diseases (AASLD). This marks the fourth consecutive year in which data from the seladelpar development program in PBC will be featured in an oral, late-breaking presentation at The Liver Meeting®.
Sujal Shah, President and CEO of CymaBay, stated, “We are making great progress towards restarting our seladelpar development program with RESPONSE as we drive to completing late-stage development of seladelpar for patients with PBC. Results from our ENHANCE study to be presented at The Liver Meeting® 2020 demonstrate the anti-cholestatic, anti-inflammatory and anti-pruritic effects of seladelpar in patients with PBC and we believe highlight the potential for seladelpar to address key unmet needs for patients suffering from this serious, life-threatening disease. In addition to our core focus in PBC, we continue to evaluate seladelpar and our other early-stage clinical assets for other indications and development opportunities.”
Recent Corporate Highlights
Start-up activities initiated for RESPONSE, a 52-week, placebo-controlled, randomized, global, phase 3 registration study evaluating the safety and efficacy of seladelpar in patients with PBC. This study is intended to enroll 180 patients, who have an inadequate response to, or intolerance to, ursodeoxycholic acid, in a 2:1 randomization to oral, once daily seladelpar 10 mg or placebo. The primary outcome measure is the responder rate at 52 weeks. A responder is defined as a patient who achieves an alkaline phosphatase level < 1.67 times 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 for patients with moderate to severe pruritus at baseline assessed by a numerical rating scale recorded with an electronic diary.
CymaBay has also initiated start-up activities for ASSURE, an open-label, long-term study of seladelpar in patients with PBC intended to collect additional safety data to support registration. This study is expected to begin enrolling patients in early 2021. The first subjects will consist of patients who have participated in the Company’s prior studies of seladelpar in PBC, including the open-label phase 2 study, ENHANCE and the Company’s long-term safety study. As patients complete RESPONSE, and potentially other future PBC studies with seladelpar, they may also have the opportunity to enroll in ASSURE.
Announced results from two separate studies of seladelpar in patients with PBC and NASH that will be featured at The Liver Meeting® 2020 sponsored by the American Association for the Study of Liver Diseases to be held virtually November 13th – 16th

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 at baseline versus placebo. Overall, seladelpar appeared to be safe and well-tolerated in this study.
In November 2020, announced a study to evaluate the potential for MBX-2982, a GPR119 agonist, to prevent hypoglycemia in patients with type 1 diabetes (T1D). Insulin-induced hypoglycemia in diabetes is a significant limiting factor in achieving the desired glucose control and is the cause of significant morbidity. In recent preclinical studies, GPR119 agonists were shown to enhance glucagon secretion in response to low glucose levels and were able to prevent hypoglycemia in animal models. The Phase 2a proof-of-pharmacology study will assess whether MBX-2982 can enhance glucagon secretion during insulin-induced hypoglycemia in subjects with T1D. The study will be led by the AdventHealth Translational Research Institute in Orlando, Florida and fully funded by The Leona M. and Harry B. Helmsley Charitable Trust. CymaBay retains full rights to MBX-2982.
CymaBay held $161.3 million in cash, cash equivalents and short-term investments as of September 30, 2020 and had no outstanding debt. We believe that cash and investments are 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 the restarting of its clinical development of seladelpar, and will continue to take actions available to mitigate them where possible. Further, all CymaBay’s actions will continue to be guided by a commitment to ensuring the health and safety of its employees as well as patients enrolled in its clinical studies.
Third Quarter and Nine Months Ended September 30, 2020 Financial Results
Research and development expenses for the three months ended September 30, 2020 were $7.7 million, compared to $23.2 million for the three months ended September 30, 2019. Research and development expenses for the nine months ended September 30, 2020 were $25.2 million, compared to $62.9 million for the nine months ended September 30, 2019. Research and development expenses in the first three and nine months of 2020 were 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 September 30, 2020 remained flat at $4.5 million when compared to the three months ended September 30, 2019. General and administrative expenses for the nine months ended September 30, 2020 were $12.2 million, compared to $14.7 million for the nine months ended September 30, 2019. General and administrative expenses in the first nine months of 2020 were lower than the corresponding period 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 after stopping development of seladelpar, while investigating the findings in the NASH phase 2 study.
Net loss for the three months ended September 30, 2020 was $11.4 million, or ($0.17) per diluted share, compared to a net loss of $26.3 million, or ($0.38) per diluted share in the three months ended September 30, 2019. Net loss for the nine months ended September 30, 2020 was $35.2 million, or ($0.51) per diluted share, compared to a net loss of $73.4 million, or ($1.10) per diluted share in the nine months ended September 30, 2019. Net loss was lower in the first three and nine 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 after stopping development of seladelpar in the fourth quarter of 2019, while beginning an investigation of the findings in the NASH phase 2 study. Given the FDA’s subsequent lifting of the clinical hold and CymaBay’s restart of the seladelpar program and further exploration of other clinical development opportunities, losses are expected to increase in the future as the Company continues its restarted clinical development activities.
