–The Phase 3 ENLIGHTEN-Fibrosis trial in patients with non-cirrhotic metabolic dysfunction-associated steatohepatitis (MASH) and the Phase 3 ENLIGHTEN-Cirrhosis trial in patients with compensated cirrhosis (F4) are enrolling patients–

–Phase 3 ENTRUST trial for patients with severe hypertriglyceridemia (SHTG) continues to enroll patients and topline data is expected in 2025–

SAN FRANCISCO, Aug. 05, 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 second quarter ended June 30, 2024.

“We are thrilled to have initiated two pivotal Phase 3 trials addressing non-cirrhotic MASH (ENLIGHTEN-Fibrosis in F2-F3) and MASH with compensated cirrhosis (ENLIGHTEN-Cirrhosis in F4), which have the potential for accelerated approval using histology in both trials,” stated Rohan Palekar, CEO of 89bio. “In parallel to executing on three Phase 3 trials in both MASH and SHTG, we continue to take important steps forward that we believe will strategically enhance our preparedness for potential commercialization of pegozafermin including commercial manufacturing readiness. We believe in the prospects of pegozafermin in MASH, given the urgent medical need for more severe patients with advanced fibrosis and cirrhosis, in addition to the significant opportunity in SHTG to help patients who are refractory to current standard of care."

Recent Highlights and Anticipated Milestones

Metabolic dysfunction-associated steatohepatitis (MASH)

• ENLIGHTEN-Cirrhosis, a Phase 3 trial of pegozafermin in MASH patients with compensated cirrhosis (F4), was initiated in the second quarter.
  • ENLIGHTEN-Cirrhosis is a global Phase 3, randomized, double-blind, placebo-controlled trial evaluating pegozafermin for the treatment of MASH patients with compensated cirrhosis (F4). The trial will enroll approximately 760 patients, who will be randomized in a 1:1 ratio to either receive 30mg of pegozafermin administered weekly or a placebo. A subset of the 760 patients will be evaluated at 24 months to assess fibrosis regression, potentially supporting an accelerated approval filing in the United States and conditional approval in Europe. The primary endpoint of fibrosis regression is defined as an improvement in fibrosis from F4 to an earlier stage. The primary endpoint for the final analysis will be a clinical outcome composite and is expected to form the basis for confirmatory or full approval.
• Data from the ENLIVEN Phase 2b trial was presented at the European Association for the Study of the Liver Congress (EASL) and was selected for the Poster Tour, a dedicated discussion session.
  
  

Severe Hypertriglyceridemia (SHTG)

• Enrollment is ongoing in ENTRUST, the Phase 3 trial evaluating the efficacy, safety and tolerability of pegozafermin in patients with SHTG.
• Topline results from this trial are expected to be reported in 2025.

Corporate Update

• Dr. Charles McWherter joined the Board of Directors, effective July 30, 2024. Dr. McWherter most recently served as Chief Scientific Officer and President of Research and Development of CymaBay Therapeutics, until it was acquired by Gilead Sciences in March 2024.
  
  

Second Quarter 2024 Financial Results

Cash Position. As of June 30, 2024, 89bio had cash, cash equivalents and marketable securities of $531.4 million, which does not include $19.4 million and $5.3 million of proceeds received by the Company subsequent to June 30, 2024 from the exercise of common stock warrants prior to June 30, 2024 and on July 1, 2024, respectively.

Research and Development (R&D) Expenses. R&D expenses were $44.9 million for the three months ended June 30, 2024, compared to $34.9 million for the three months ended June 30, 2023. The increase in R&D expenses was primarily driven by increases in clinical development, contract manufacturing, and personnel-related expenses, including stock-based compensation driven by higher headcount.

General and Administrative (G&A) Expenses. G&A expenses were $8.6 million for the three months ended June 30, 2024, compared to $7.2 million for the three months ended June 30, 2023. The increase in G&A expenses was primarily due to an increase in professional fees and personnel-related expenses including stock-based compensation driven by higher headcount.

Net Loss. 89bio reported a net loss of $48.0 million for the three months ended June 30, 2024, compared to a net loss of $38.4 million for the three months ended June 30, 2023. The increase in net loss was primarily attributable to increased R&D expenses to advance the company's Phase 3 clinical trials, increased G&A expenses associated with higher headcount, and expenses to support the Company's expanded operations. These increases in operating expenses were offset in part by the increase in net interest income and other to $6.5 million for the three months ended June 30, 2024 from $4.6 million for the three months ended June 30, 2023, mainly due to a change in interest rates and an increase in the average invested balances.
