WOBURN, Mass., June 01, 2019 (GLOBE NEWSWIRE) -- Replimune Group, Inc. (NASDAQ: REPL), a biotechnology company developing oncolytic immuno-gene therapies derived from its Immulytic™ platform, today announced that the Phase 2 portion of the Company’s Phase 1/2 clinical trial of RP1 alone and in combination with nivolumab anti-PD1 therapy has initiated. In the Phase 2 portion of the clinical trial, RP1 in combination with nivolumab will be tested in four 30-patient cohorts of patients with melanoma, non-melanoma skin cancers (NMSC), metastatic bladder cancer or microsatellite instability-high (MSI-H) tumors. Enrollment is now open in the melanoma, NMSC and bladder cancer cohorts, and enrollment in the MSI-H cohort will open as soon as a protocol-required MSI-H patient is evaluable from Phase 1. The patients enrolled into the melanoma cohort either will be treatment naïve or have received one prior systemic therapy, and the patients enrolled into the other three cohorts will all be naïve to anti-PD1 therapy.
Data relating to the Phase 1 portion of the clinical trial, including biomarker data, is expected to be presented at a medical conference in the fourth quarter of 2019. The Phase 1 portion tested single agent RP1 by direct injection into a single superficial or nodal tumor and by imaging guided injection into a single visceral tumor in patients with advanced heavily pre-treated cancers who failed available therapy to define the recommended Phase 2 dose. Following determination of the recommended Phase 2 dose, an expansion group of advanced cancer patients who failed available therapy then received RP1 at the recommended Phase 2 dose in combination with nivolumab at standard clinical doses.
Poster Presentation at ASCO
The Company also announced that a trial in progress (TiP) poster will be presented today at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting currently being held in Chicago, IL. The poster describes the design and current status of the Phase 1/2 clinical trial, including the tumor types of the patients enrolled, and will be made available on the Company’s website at the time of presentation.

RP1 is Replimune’s first Immulytic™ product candidate to enter the clinic and is based on a proprietary new strain of herpes simplex virus engineered to maximize tumor killing potency, the immunogenicity of tumor cell death and the activation of a systemic anti-tumor immune response.
Replimune Group, Inc., headquartered in Woburn, MA, was founded in 2015 to develop the next generation of “oncolytic immune-gene therapies” for the treatment of cancer. Replimune is developing novel, proprietary therapeutics intended to improve the direct cancer-killing effects of selective virus replication and the potency of the immune response to the tumor antigens released. The Company’s Immulytic™ platform is designed to maximize systemic immune activation, in particular to tumor neoantigens, through robust viral-mediated immunogenic tumor cell killing and the delivery of optimal combinations of immune-activating proteins to the tumor and draining lymph nodes. The approach is expected to be highly synergistic with immune checkpoint blockade and other approaches to cancer treatment. Replimune intends to progress these therapies rapidly through clinical development in combination with other immuno-oncology products with complementary mechanisms of action.
