ONCR-177, our lead candidate, is an intratumorally administered oncolytic Herpes Simplex Virus (oHSV) viral immunotherapy for the treatment of multiple solid tumor cancers. ONCR-177 fights tumors through multiple mechanisms, including inherent oncolytic activity, immune stimulation elicited by viral infection and the expression of five transgenes (IL-12, CCL4, FLT3LG, anti-PD-1 and anti-CTLA-4).

Preclinical Findings
In preclinical studies, we have observed durable virus and immune system-driven anti-tumor activity in injected tumors as well as abscopal activity. We have also observed that ONCR-177 is well tolerated in a validated animal safety model of oHSV when administered intravenously.

Development Status
We are currently enrolling patients in a Phase 1, open-label, multi-center, dose-escalation and expansion study designed to evaluate the safety and tolerability and to determine the recommended Phase 2 dose as well as preliminary anti-tumor activity of ONCR-177 alone and in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in adult subjects with advanced and/or refractory cutaneous, subcutaneous or metastatic nodal solid tumors (ClinicalTrials.gov Identifier: NCT04348916).
