IMPACT trial is evaluating the safety and efficacy of pemvidutide in approximately 190 subjects with MASH; top-line efficacy data expected in Q2 2025

End-of-Phase 2 Meeting for the obesity program with U.S. Food and Drug Administration (FDA) has been scheduled for early November 2024

Company plans to submit Investigational New Drug (IND) applications for pemvidutide in up to three additional indications beginning in Q4 2024

GAITHERSBURG, Md., Sept. 30, 2024 (GLOBE NEWSWIRE) -- Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced completion of patient enrollment in IMPACT, its Phase 2b biopsy-driven trial evaluating pemvidutide in metabolic dysfunction-associated steatohepatitis (MASH) and provided an update on additional development and regulatory initiatives related to pemvidutide.

“We continue to make important advancements in the development of pemvidutide and are excited to have completed enrollment in the IMPACT trial, with top-line efficacy data expected in the second quarter of 2025,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “We are also excited to have received FDA confirmation of the End-of-Phase 2 meeting for our obesity program, which is scheduled for early November. Furthermore, we are planning to file INDs for Phase 2 studies of pemvidutide in up to three additional indications. These initiatives are expected to expand the differentiation of pemvidutide in the metabolic disease space and enhance its long-term value proposition.”

“IMPACT will be the first incretin-based study to read out on a biopsy-driven fibrosis endpoint at only 24 weeks. I believe the combination of direct liver effects and weight loss conferred by pemvidutide offers an important advantage over other approaches to the treatment of MASH and I look forward to the results of the IMPACT trial with great optimism,” said Dr. Mazen Noureddin, M.D., MHSc, Professor of Medicine at Houston Methodist Hospital, Director, Houston Research Institute and Principal Investigator on the IMPACT trial.

“We look forward to aligning with the FDA on our Phase 3 clinical development plan for pemvidutide in obesity at our End-of-Phase 2 meeting in early November,” added Dr. Garg. “Our proposed registrational program leverages the unique attributes of pemvidutide, which we believe will benefit patients with obesity, excess liver fat and elevated serum lipids while preserving lean mass.”

Altimmune also expects to file IND applications for pemvidutide in up to three additional indications with the first of these IND submissions in Q4 2024. The company plans to disclose details on these indications following alignment with the FDA. Preparations for the first trial are underway, with initiation planned for H1 2025.
