CAMBRIDGE, Mass., July 31, 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 U.S. Food and Drug Administration (FDA) granted Fast Track designation for its lead clinical-stage program, IMM-1-104, as a first-line treatment for patients with pancreatic ductal adenocarcinoma (PDAC). In February 2024, the Company announced Fast Track designation for IMM-1-104 as second-line treatment for patients with PDAC who have failed one previous line of therapy. IMM-1-104 is designed to provide universal-RAS activity through Deep Cyclic Inhibition of the MAPK pathway with once-daily oral dosing.

“First-line pancreatic cancer patients are eligible and actively enrolling in our Phase 2a study, in two arms evaluating IMM-1-104 in combination with chemotherapy,” said Ben Zeskind, Ph.D., Co-founder and Chief Executive Officer of Immuneering. “With Fast Track designation now granted for IMM-1-104 in both first and second-line pancreatic cancer, we have the potential to help a broader population of patients impacted by one of the most difficult to treat cancers. Our Phase 2a study also includes an arm evaluating IMM-1-104 as monotherapy in first and second-line pancreatic cancer patients, along with monotherapy arms focused on RAS mutant melanoma and RAS mutant non-small cell lung cancer. We look forward to sharing initial data from multiple arms of the study this year.”

About Fast Track Designation

Fast Track Designation is a program designed to facilitate the development and expedite the review of medicines with the potential to treat serious conditions and fulfill an unmet medical need. An investigational medicine that receives Fast Track Designation may be eligible for more frequent interactions with the FDA to discuss the candidate’s development plan and, if relevant criteria are met, may be eligible for accelerated approval and priority review.
