SAN FRANCISCO, Aug. 11, 2022 (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 ended June 30, 2022.

“In the second quarter we reported positive topline results from the ENTRIGUE Phase 2 trial of pegozafermin in patients with severe hypertriglyceridemia (SHTG) and further strengthened our financial resources, which we believe will carry us through key value-driving milestones as we transition into a late-stage company,” said Rohan Palekar, Chief Executive Officer of 89bio. “We are well positioned to drive our clinical development program forward and build on the encouraging data that underscore pegozafermin’s broad metabolic effects and favorable safety and tolerability profile. The results from the ENTRIGUE Phase 2 trial position pegozafermin as potentially the first FGF21 analog to market and bring us one step closer to providing a differentiated therapeutic option for the treatment of cardio-metabolic and liver disease. We plan to present ENTRIGUE data at the upcoming European Society of Cardiology Congress and remain on track to initiate our Phase 3 trial in SHTG in the first half of 2023 pending our end of Phase 2 meeting with the FDA. Additionally, we expect to report topline data from our Phase 2b ENLIVEN trial in NASH in the first quarter of 2023.”

Recent Highlights and Anticipated Milestones


Data from the Phase 2 ENTRIGUE trial of pegozafermin to be presented as a late-breaker at European Society of Cardiology (ESC) Congress 2022.

  • Data to be presented by Deepak L. Bhatt, MD, MPH, Brigham and Women’s Hospital and Harvard Medical School during the Late-Breaking Science-Innovation in Drug Treatment session on Friday, August 26th at 6 a.m. ET/ 3 a.m. PT/ 12 p.m. CEST.  

Reported positive topline data for the Phase 2 ENTRIGUE trial of pegozafermin in SHTG patients; initiation of Phase 3 trial expected in the first half of 2023.

  • Treatment with pegozafermin resulted in clinically meaningful and statistically significant reductions in triglycerides (TG) from baseline across all doses (with a 63% reduction in the highest dosing group; p<0.001), statistically significant improvements in key markers of cardiovascular risk (non-HDL-C and apo B), reductions in liver fat, and improvements in glycemic control markers.
  • Results were consistent in patients not on background therapy or on background therapy (consistent results on statins or statin combos, prescription fish oils, and fibrates) and across various subgroups, including those with the greatest disease burden, such as patients with type 2 diabetes and those with baseline TG levels ≥750 mg/dL.
  • Consistent with prior studies, pegozafermin was generally well tolerated with a favorable safety profile across doses. The most commonly reported treatment-related adverse events were nausea, diarrhea, and injection site reactions, all which were classified as mild or moderate. No tremors or transaminase elevation adverse events were observed. There were no drug-related serious adverse events and two Grade 2 treatment-related discontinuations.


Expect to complete enrollment in the third quarter of 2022 with over 200 patients in the ENLIVEN Phase 2b trial; topline data expected in the first quarter of 2023.

  • ENLIVEN is a Phase 2b trial designed to evaluate the safety and efficacy of weekly or every two-week pegozafermin for the treatment of patients with fibrosis stage F2 - F3 NASH and NAS ≥ 4.

Presented additional pegozafermin data at the European Association for the Study of the Liver (EASL) International Liver Congress™ 2022.

  • Three poster presentations were showcased:
    • Results from an open-label expansion cohort in the Phase 1b/2a proof-of-concept study evaluating pegozafermin for the treatment of NASH demonstrated clinically meaningful improvements on HbA1c, adiponectin, and lipid parameters with notable body weight reduction and favorable safety and tolerability observed.
    • Treatment with pegozafermin in advanced fibrosis patients, 85% of which had type 2 diabetes and were on background therapy for diabetes, hyperlipidemia or both, demonstrated significant metabolic benefits in addition to robust beneficial effects on the liver, with favorable safety and tolerability. Together, these data suggest that pegozafermin has the potential to address broader cardiometabolic risks in addition to liver related outcomes.
    • Treatment with pegozafermin demonstrated a robust pharmacokinetic/pharmacodynamic effect independent of NASH fibrosis stage, with a favorable safety and tolerability profile observed following a single 30-mg dose. These findings highlight the feasibility of assessing treatment response in F4 patients with compensated hepatic function without requiring a dose adjustment.

Corporate Updates:

  • Completed underwritten public offering of common stock, warrants to purchase shares of common stock and pre-funded warrants to purchase shares of common stock, raising approximately $94.5 million in gross proceeds.

Second Quarter 2022 Financial Results

Cash Position. As of June 30, 2022, 89bio had cash, cash equivalents, and short-term investments of $139.3 million. This includes $28.2 million in proceeds from pre-funded warrants that the company received prior to the closing of the offering. Pro-forma cash as of June 30, 2022 was approximately $200 million, including the remainder of the net proceeds received from the offering.

Research and Development (R&D) Expenses. R&D expenses were $19.7 million for the three months ended June 30, 2022, compared to $15.6 million for the three months ended June 30, 2021. The increase in R&D expenses was primarily driven by increases in clinical development costs related to our ongoing clinical trials and personnel-related expenses, offset in part by a decrease in contract manufacturing costs and lower overhead costs.

General and Administrative (G&A) Expenses. G&A expenses were $5.1 million for the three months ended June 30, 2022, compared to $4.9 million for the three months ended June 30, 2021. The increase in G&A expenses was primarily due to an increase in costs related to personnel expenses.

Net Loss. 89bio reported a net loss of $25.1 million for the three months ended June 30, 2022, compared to $20.7 million for the three months ended June 30, 2021. 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.
