Excerpt from the Press Release:

CAMBRIDGE, Mass., March 11, 2024 (GLOBE NEWSWIRE) — Immuneering Corporation (Nasdaq: IMRX), a clinical-stage oncology company seeking to develop and commercialize universal-RAS/RAF medicines for broad populations of cancer patients, today announced that the first patient has been dosed in the Phase 2a portion of its Phase 1/2a clinical trial of IMM-1-104, its lead program. IMM-1-104 is designed to provide universal-RAS activity through deep cyclic inhibition of MEK in the MAPK pathway with once-daily oral dosing.

“The initiation of our Phase 2a study is an important milestone for Immuneering, as we evaluate IMM-1-104 in larger numbers of patients with specific types of cancer, at earlier stages of disease, with a broader set of endpoints, and a growing team of both investigators and study sites,” said Ben Zeskind, Ph.D., Co-founder and Chief Executive Officer of Immuneering. “The Phase 2a portion includes both monotherapy and combination arms, all in tumor types where we believe IMM-1-104 has the greatest potential to make a positive impact. We are excited to be evaluating IMM-1-104 as a combination therapy for the first time in the clinic, with an initial focus on PDAC in the first-line setting based on compelling, previously generated preclinical data, well-understood disease biology, and a vast unmet medical need. We look forward to sharing our topline Phase 1 data this month, and then reporting initial results from multiple arms of our Phase 2a later in 2024, which is shaping up to be a data-rich year for our company.”

The Phase 2a portion of the Phase 1/2a clinical trial of IMM-1-104 is expected to include approximately 150 patients in five arms at our recommended Phase 2 dose of 320 mg once daily.
