89bio, Inc. (NASDAQ:ETNB): Advancing Innovative Therapies for Liver and Cardiometabolic Diseases

Business Overview and Detailed Company History: 89bio, Inc. is a clinical-stage biopharmaceutical company dedicated to developing and commercializing innovative therapies for the treatment of liver and cardiometabolic diseases. With a focus on addressing unmet medical needs, the company has established a robust pipeline led by its lead candidate, pegozafermin, which is currently undergoing pivotal trials for the treatment of metabolic dysfunction-associated steatohepatitis (MASH) and severe hypertriglyceridemia (SHTG).

89bio was founded in 2018 with the mission of advancing therapies for liver and cardiometabolic diseases. The company's origins trace back to January 2018, when it was incorporated in Israel as 89Bio Ltd. In June 2019, the company was reorganized and incorporated in Delaware as 89bio, Inc. to carry on the business of 89Bio Ltd.

The company's primary focus has been the development of pegozafermin, a specifically engineered glycoPEGylated analog of fibroblast growth factor 21 (FGF21). Pegozafermin is currently in late-stage clinical trials for the treatment of MASH and SHTG, two conditions that represent significant unmet medical needs.

In April 2018, 89bio entered into two Asset Transfer and License Agreements with Teva Pharmaceutical Industries Ltd., through which it acquired certain patents, intellectual property, and other assets related to Teva's glycoPEGylated FGF21 program, including pegozafermin. This acquisition provided the company with the rights to develop and commercialize pegozafermin globally.

Since its inception, 89bio has faced several challenges in advancing the development of pegozafermin. The company has had to navigate the complex regulatory landscape for therapies targeting MASH and SHTG, as these are relatively new disease areas without established regulatory precedents. Additionally, 89bio has encountered difficulties in enrolling patients for its clinical trials due to the challenges in diagnosing MASH and identifying SHTG patients.

To fund its operations and research and development activities, 89bio has raised capital through various means, including public offerings of its common stock and the issuance of debt. In 2019, the company completed an initial public offering, raising $157.7 million. Over the years, 89bio has also entered into at-the-market (ATM) equity offering programs and term loan facilities to further strengthen its financial position.

Over the past several years, 89bio has made significant progress in advancing pegozafermin through its clinical development programs. In 2020 and 2022, the company reported positive topline results from its Phase 1b/2a trial of pegozafermin in MASH patients, which informed the advancement of its subsequent clinical strategy. In March 2023, 89bio announced positive topline 24-week data from its Phase 2b ENLIVEN trial of pegozafermin in MASH patients, with the 44 mg every-two-week and 30 mg weekly dose groups both meeting the primary histology endpoints.

In September 2023, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to pegozafermin for the treatment of MASH, recognizing the potential of the therapy to address this significant unmet medical need. Furthermore, in March 2024, the European Medicines Agency (EMA) granted Priority Medicines (PRIME) designation to pegozafermin for the treatment of MASH, based on the promising clinical data from the Phase 2b ENLIVEN trial.

Building on these regulatory milestones, 89bio initiated its Phase 3 ENLIGHTEN program for pegozafermin in MASH in the first and second quarters of 2024. The ENLIGHTEN program includes two pivotal trials: ENLIGHTEN-Fibrosis in patients with fibrosis stage F2-F3, and ENLIGHTEN-Cirrhosis in patients with compensated cirrhosis (F4).

In parallel, 89bio is also advancing the development of pegozafermin for the treatment of SHTG. In June 2022, the company announced positive topline results from the Phase 2 ENTRIGUE trial of pegozafermin in SHTG patients, which met its primary endpoint. Based on this data, 89bio initiated its Phase 3 ENTRUST trial, the first of two recommended Phase 3 trials in SHTG, in the second quarter of 2023. Topline data from the ENTRUST trial are expected in 2025.

The company's recent corporate updates include the strengthening of its Board of Directors and Executive Leadership Team. In October 2024, 89bio appointed Charles McWherter, Ph.D. to its Board of Directors, and in September 2024, the company welcomed Francis Sarena as Chief Operating Officer and Teresa Perney, Ph.D. as Chief Regulatory and Quality Officer.

In April 2024, 89bio entered into a collaboration agreement with BiBo Biopharma Engineering Co., Ltd. to construct a production facility in China specifically designed to supply pegozafermin for commercial needs, if approved. This strategic partnership aims to secure manufacturing capacity for pegozafermin, ensuring a reliable supply chain for potential future commercialization.
