Patients will initiate treatment with pembrolizumab at the start of the trial and receive up to 18 treatment cycles (approximately 2 years). Immunization with the EVX-01 will be initiated at Week 12. In total, 10 doses of EVX-01 will be administered intramuscularly, with 6 doses given two weeks apart and 4 booster doses at later time points.
The purpose of this single arm, multi-national clinical trial in patients with metastatic or unresectable melanoma is to evaluate the BOR and compare it to historical data on patients on anti-PD1 treatment with pembrolizumab alone.
