SAN FRANCISCO, Nov. 08, 2023 (GLOBE NEWSWIRE) -- 89bio, Inc. (Nasdaq: ETNB), a clinical-stage biopharmaceutical company focused on the development and commercialization of innovative therapies for the treatment of liver and cardiometabolic diseases, today reported its financial results for the third quarter ended September 30, 2023.

“We are making excellent progress in developing pegozafermin as a potential leading treatment for liver and cardiometabolic diseases,” stated Rohan Palekar, CEO of 89bio. “We believe the FDA's breakthrough therapy designation is a significant milestone, and further validates pegozafermin’s potential in NASH. Pending regulatory feedback, we expect to initiate our Phase 3 program in NASH in the first half of 2024. Additionally, we are continuing to enroll patients in ENTRUST, the Phase 3 trial of pegozafermin in patients with SHTG. Together, these advancements across our late-stage clinical development programs bring us closer to addressing the significant disease burden and unmet medical needs of patients with NASH and SHTG.”

Third Quarter 2023 Financial Results

Cash Position. As of September 30, 2023, 89bio had cash, cash equivalents and short-term available-for-sale securities totaling $448.3 million.

Research and Development (R&D) Expenses. R&D expenses were $31.4 million for the three months ended September 30, 2023, compared to $22.2 million for the three months ended September 30, 2022. The increase in R&D expenses was primarily driven by increases in contract manufacturing costs and personnel expenses, offset by a decrease in clinical development costs.

General and Administrative (G&A) Expenses. G&A expenses were $7.9 million for the three months ended September 30, 2023, compared to $4.8 million for the three months ended September 30, 2022. The increase in G&A expenses was primarily due to an increase in personnel costs, stock-based compensation, and expenses related to professional services.

Net Loss. 89bio reported a net loss of $34.7 million for the three months ended September 30, 2023, compared to a net loss of $26.8 million for the three months ended September 30, 2022. The increase in net loss is primarily attributable to increased R&D expenses for our programs and increased G&A expenses associated with operating as a public company.
