SAN FRANCISCO, Nov. 07, 2024 (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, 2024.

“We continue to execute on our three pivotal Phase 3 trials for pegozafermin in MASH and SHTG,” stated Rohan Palekar, CEO of 89bio. “Building on the positive momentum from ENLIGHTEN and ENTRUST, we have made strategic additions to our Board of Directors and Executive Leadership Team, as well as bolstered our financial position with support from K2 HealthVentures. These efforts collectively underscore our confidence in pegozafermin’s anti-fibrotic and broad metabolic effects across multiple indications where significant opportunities remain to offer better treatment for those living with MASH and SHTG.”

Recent Highlights and Anticipated Milestones

Metabolic dysfunction-associated steatohepatitis (MASH)

• ENLIGHTEN-Fibrosis and ENLIGHTEN-Cirrhosis are global Phase 3 trials in non-cirrhotic (F2-F3) MASH patients with fibrosis and in compensated cirrhotic (F4) MASH patients, respectively. The histology endpoints of both trials could potentially support accelerated approval in the United States and conditional approval in Europe. Both trials will continue for outcomes, to potentially support full approval. The trials were initiated earlier this year and are continuing to enroll patients.
• New analyses of data from the ENLIVEN Phase 2b trial will be presented at the upcoming 75^th Annual American Association for the Study of Liver Diseases (AASLD) The Liver Meeting^® 2024 being held November 15 to 19, 2024. The details on these upcoming presentations can be found here.

Severe Hypertriglyceridemia (SHTG)

• Enrollment is ongoing in ENTRUST, the Phase 3 trial evaluating the efficacy, safety and tolerability of pegozafermin in patients with SHTG. 89bio expects to report topline data from this trial in 2025.

• Charles McWherter, Ph.D. was appointed to the Board of Directors, effective July 30, 2024. Dr. McWherter is a seasoned biotech industry veteran who brings decades of biotech and pharmaceutical experience, most recently serving as Chief Scientific Officer and President of Research and Development at CymaBay Therapeutics, Inc.

• Francis Sarena joined the Company as Chief Operating Officer, effective August 5, 2024. Mr. Sarena is a seasoned C-suite, biotech executive with over 25 years of experience. Before joining 89bio, he served as President and Chief Operating Officer at Apexigen, Inc.

An additional $35 million is available to draw at the Company’s discretion through June 30, 2025.

Third Quarter 2024 Financial Results

Cash Position. As of September 30, 2024, 89bio had cash, cash equivalents and marketable securities of $423.8 million.

Research and Development (R&D) Expenses. R&D expenses were $141.4 million for the three months ended September 30, 2024, compared to $31.4 million for the three months ended September 30, 2023. The increase in R&D expenses was primarily driven by a payment for the achievement of milestones totaling $81.0 million to BiBo Biopharma Engineering Co., Ltd. (“BiBo”), with whom the Company entered into a collaboration agreement earlier this year for the commercial supply of pegozafermin. The increase in R&D expenses was also driven by an increase in clinical development costs, contract manufacturing costs, and personnel-related expenses, including stock-based compensation due to higher headcount.

General and Administrative (G&A) Expenses. G&A expenses were $10.5 million for the three months ended September 30, 2024, compared to $7.9 million for the three months ended September 30, 2023. The increase in G&A expenses was primarily due to an increase in personnel-related expenses including stock-based compensation driven by higher headcount, professional fees and facilities and other expenses.

Net Loss. 89bio reported a net loss of $149.1 million for the three months ended September 30, 2024, compared to a net loss of $34.7 million for the three months ended September 30, 2023. The increase in net loss was primarily attributable to increased R&D expenses to advance the Company's Phase 3 clinical trials, milestone payments to BiBo, increased G&A expenses associated with higher headcount, and expenses to support the Company's expanded operations.
