SAN FRANCISCO, March 24, 2021 (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 cardio-metabolic diseases, today reported its financial results for the quarter and full year ended December 31, 2020.

“2020 was a transformative year for 89bio, and we are encouraged by the significant progress made in advancing BIO89-100 through the clinic. This was highlighted by our Phase 1b/2a data in NASH patients that underscored the potential for BIO89-100 as a best-in-class FGF21 analog and provided the impetus for advancing BIO89-100 into a Phase 2b trial for the treatment of NASH,” said Rohan Palekar, Chief Executive Officer of 89bio. “We are anticipating some important clinical milestones in 2021 that we expect will continue to validate BIO89-100’s potential in both NASH and SHTG.”

Recent Highlights and Anticipated Milestones

• Presented updated clinical data from Phase 1b/2a study of BIO89-100 in NASH at AASLD’s The Liver Meeting® 2020 and at ENDO 2021. The data presented at AASLD confirmed BIO89-100’s compelling efficacy profile and favorable tolerability with weekly and every two-week dosing. New analyses demonstrated the significant correlation between relative reductions in MRI-PDFF and serum ALT in patients treated with BIO89-100. New analyses of BIO89-100’s Phase 1b/2a study data presented at ENDO 2021 demonstrated significant reductions in liver volume of up to 15% and liver fat volume of up to 65% at 13 weeks compared to baseline in treated patients as measured by MRI-PDFF.
• Initiate the Phase 2b trial in NASH patients in the first half of 2021.
• Report topline data from the paired-biopsy, open-label histology cohort in NASH patients by year-end 2021. This cohort is enrolling approximately 20 patients with biopsy-confirmed NASH and will provide an early opportunity to demonstrate BIO89-100’s benefits on histology endpoints.
• Report topline data from the Phase 2 ENTRIGUE study of BIO89-100 in SHTG patients in the second half of 2021. ENTRIGUE is a multi-center, randomized, double-blind, placebo-controlled study designed to evaluate safety, efficacy and tolerability in patients that will receive BIO89-100 administered weekly (9mg, 18mg or 27 mg), every two weeks (36mg) or placebo. The primary endpoint is the reduction in fasting triglycerides from baseline. Key secondary endpoints include other lipids and metabolic markers and change in liver fat measured by MRI-PDFF. ENTRIGUE was expanded recently with an additional cohort of patients on fibrates to assess the benefit of the 27 mg weekly dose of BIO89-100 when added to background fibrates. In this additional cohort, a total of 36 patients will be randomized to either BIO89-100 or placebo. The primary endpoint and key secondary endpoints are the same as in ENTRIGUE, including change in liver fat as measured by MRI-PDFF.

Fourth Quarter and Full Year 2020 Financial Results

Cash Position. As of December 31, 2020, 89bio had cash, cash equivalents, and short-term investments totaling $204.7 million compared to $93.4 million as of December 31, 2019. This included approximately $157.7 million in estimated net proceeds from underwritten public offerings of common stock in the third quarter of 2020.

Research and Development (R&D) Expenses. R&D expenses were $8.8 million and $36.2 million for the three months and year ended December 31, 2020, respectively, compared to $7.2 million and $21.4 million for the three months and year ended December 31, 2019, respectively. The increase for the year ended December 31, 2020 was primarily driven by higher clinical development, contract manufacturing, and personnel expenses.

General and Administrative (G&A) Expenses. G&A expenses were $3.8 million and $13.2 million for the three months and year ended December 31, 2020, respectively, compared to $2.4 million and $5.3 million for the three months and year ended December 31, 2019, respectively. The increase for the year ended December 31, 2020 was primarily due to higher personnel expenses and expenses relating to first full year of operations as a public company.
