• Immunome has received a clinical hold letter from the FDA requesting further information related to the preparation and administration of the IMM-BCP-01 cocktail at clinical sites
• Immunome expects to provide the requested information soon and remains on track to generate top-line clinical data for IMM-BCP-01 in the first half of 2022
• Reporting of IMM-BCP-01 activity against the Omicron variant in live virus testing by an external laboratory also remains on track for this month

Immunome, Inc. (Nasdaq: IMNM), a biopharmaceutical company that utilizes its human memory B cell platform to discover and develop first-in-class antibody therapeutics, today announced an update regarding its Investigational New Drug (IND) submission for IMM-BCP-01, a three-antibody cocktail, for the treatment of SARS-CoV-2 (COVID-19).

The Company received a clinical hold letter from the U.S. Food and Drug Administration (FDA) in response to its recently submitted IND requesting further information related to the preparation and administration of IMM-BCP-01 at clinical sites. The Company has already initiated the requisite work and expects to provide the requested information quickly.

Unrelated, the FDA also provided in the same letter valuable guidance on the clinical protocol for IMM-BCP-01, including patient selection criteria.

“We are thankful for the rapid and insightful feedback that the FDA has provided throughout our ongoing discussions and have already initiated efforts to provide the requested information,” commented Purnanand Sarma, PhD, President & CEO of Immunome. “In addition, we remain on track to report IMM-BCP-01’s activity against the Omicron variant in live virus testing by a third-party lab in January. We remain confident in our approach to address COVID-19 and look forward to providing further updates in the coming weeks.”

This investigational work was funded by the U.S. Department of Defense’s (DOD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) in collaboration with the Defense Health Agency (DHA) (Contract number: W911QY-20-9-0019).

About IMM-BCP-01

IMM-BCP-01 is a three-antibody cocktail targeting non-overlapping regions of the Spike protein of SARS-CoV-2, including highly conserved, subdominant epitopes, which elicits both ACE2 and non-ACE2 dependent neutralization, and induces natural viral clearance mechanisms, such as antibody dependent cellular cytotoxicity, complement activation and phagocytosis. When tested in vivo, these mechanisms combine to significantly reduce viral load in lungs of the hamsters infected with SARS-CoV-2, and broadly neutralize the Delta (B.1.617.2) variant in vitro, with testing against the Omicron variant ongoing. Immunome has submitted an Investigational New Drug Application with the FDA and plans to initiate a placebo-controlled dose escalation study of IMM-BCP-01 in patients infected with SARS-CoV-2, pending the FDA’s acceptance of Immunome’s IND submission. This investigational work was funded by the U.S. Department of Defense’s (DOD) Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND) in collaboration with the Defense Health Agency (DHA).
