Viralytics

Status and phase: Completed; Phase 1

Conditions: Melanoma

Treatments: Biological: CAVATAK; Drug: Pembrolizumab

Study type: Interventional

About

This study will employ a phase Ib design using the established dose of CAVATAK with pembrolizumab in subjects with advanced melanoma for whom pembrolizumab would be considered standard of care. Our hypothesis is that oncolysis of melanoma cells by CAVATAK will be important in amplifying the T-cell potentiating effects of pembrolizumab.
