Under the terms of the agreement, Incyte will initiate and sponsor the clinical trial of INCB99280 and RP1 in patients with high risk, resectable cutaneous squamous cell carcinoma (CSCC), with the clinical trial expected to initiate in early 2024.

Replimune Group, Inc. and Incyte are collaborating to a study RP1 in combination with INCB99280, Incyte’s small molecule oral PD-L1 inhibitor, in cutaneous squamous cell carcinoma (CSCC) and in other cancer types, the companies report.

RP1 is based on a proprietary new strain of herpes simplex virus engineered for robust tumor selective replication and genetically armed with a fusogenic protein (GALV-GP R-) and GM-CSF, intended to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response

Under the terms of the agreement, Incyte will initiate and sponsor the clinical trial of INCB99280 and RP1 in patients with high risk, resectable cutaneous squamous cell carcinoma (CSCC), with the clinical trial expected to initiate in early 2024. Replimune will supply Incyte with RP1 for the study and share equally in the costs of the study.

“We are excited to enter into this collaboration with Incyte to explore the use of RP1 prior to surgery as we believe that our tumor-directed oncolytic immunotherapies could have a great impact in the neoadjuvant setting both in cutaneous squamous cell carcinoma (CSCC) and in other cancer types, given the high rates of complete responses we’ve seen to date, and data indicating RP1 is generally very well tolerated,” says Robert Coffin, Chief Research and Development Officer of Replimune, in a news release. “The unique potential of the RPx platform to induce a patient-specific anti-tumor immune response with an off-the-shelf treatment speaks to the practicality and broad potential utility of the approach, and exploring its use with Incyte’s oral PD-L1 inhibitor has the potential to improve the patient experience further.”

“We look forward to collaborating with Replimune on this study evaluating INCB99280 and RP1 in patients with CSCC. Our oral PD-L1 program has shown promising safety and efficacy in early studies thus far, and we look forward to adding to the growing body of evidence for INCB99280 and learning more about its potential to improve clinical outcomes,” adds Lance Leopold, M.D., Group Vice President, Clinical Development Hematology and Oncology, Incyte.
