CAMBRIDGE, Mass., May 06, 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, recognizes the importance of early detection and treatment during Melanoma Awareness Month, and highlights RAS mutant melanoma as the focus of one of the five arms in its ongoing Phase 2a clinical study for its lead program IMM-1-104. RAF or RAS mutant melanoma is also being evaluated in its Phase 1/2a clinical study of IMM-6-415 in patients with advanced solid tumors.

Melanoma Awareness Month is held each May to raise awareness, galvanize advocates and support research efforts toward new treatments and methods of detecting melanoma, the most serious type of skin cancer. 

“We encourage people diagnosed with melanoma to speak with their physicians about having their tumors tested for biomarkers which can help determine the most appropriate next steps in their treatment,” said Joan Levy, Ph.D., Chief Science Officer, Melanoma Research Alliance. “Several biomarkers are known to drive the growth and progression of melanoma and there are therapies being clinically evaluated with the potential to target these tumor biomarkers.”

“Immuneering is proud to acknowledge Melanoma Awareness Month, especially since melanoma is a key area of focus in our development of IMM-1-104 and mutations in the RAS gene family are known to be present in approximately 20-25% of all melanomas,” said Brett Hall, Ph.D., Chief Scientific Officer, Immuneering Corporation. “We chose RAS mutant melanoma to be one of five arms in our Phase 2a trial of IMM-1-104, where we are investigating our lead development candidate as either monotherapy or in combination and are also evaluating RAF or RAS mutant melanoma in our Phase 1/2a clinical study with IMM-6-415. We are excited at the prospect of adding IMM-1-104 and IMM-6-415 to the melanoma treatment armamentarium and look forward to updating patients and physicians as we report data.”

At the AACR-NCI-EORTC conference in October 2023, Immuneering presented preclinical data including expanded benchmarking of IMM-1-104 as a single agent across more than 190 patient-aligned models in humanized 3D-tumor growth assays, which demonstrated high sensitivity in a wide range of MAPK-driven tumor types, including models of RAS and RAF mutant melanoma, as well as pancreatic cancer, and lung cancer. Preclinical data the company has presented related to melanoma includes data showing that IMM-1-104 inhibits tumor growth in an animal model of NRAS mutant melanoma to a greater extent than binimetinib, and that IMM-6-415 in combination with encorafenib inhibits tumor growth in an animal model of BRAF mutant melanoma to a greater extent that binimetinib plus encorafenib.

IMM-1-104 aims to achieve universal-RAS activity that selectively impacts cancer cells to a greater extent than healthy cells, through Deep Cyclic Inhibition of the MAPK pathway with once-daily dosing. In the Phase 2a portion of Immuneering’s ongoing IMM-1-104 Phase 1/2a clinical trial (NCT05585320), IMM-1-104 is being evaluated as both monotherapy and in select combinations with approved chemotherapeutic agents. The Phase 2a portion includes five arms, one of which focuses on RAS-mutant melanoma, another focused on RAS mutant non-small cell lung cancer (NSCLC), and three arms focused on patients with pancreatic cancer. The company expects initial data from multiple Phase 2a arms in 2024.

IMM-6-415 is a Deep Cyclic Inhibitor of the MAPK pathway designed with unique drug-like properties including a shorter half-life for an accelerated cadence. IMM-6-415 is currently being evaluated in a Phase 1/2a study in patients with advanced solid tumors harboring RAF or RAS mutations. (NCT06208124). The Phase 1 portion of the Phase 1/2a clinical trial is an open-label study designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of IMM-6-415 in patients with advanced RAF/RAS mutant solid tumors. The trial will include solid tumor patients with any mutation in RAF, KRAS, NRAS, or HRAS who meet the enrollment criteria. The company expects initial PK, PD and safety data for IMM-6-415 in 2024.
