Official title

An Open-label, Phase II, Multicenter Study of Enhancing Pembrolizumab Responses in Melanoma Through Intratumoral pIL-12 Electroporation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a multicenter, Phase II, open-label, 42-patient single-arm trial of intratumoral pIL-12 electroporation (EP) in combination with pembrolizumab in patients with melanoma. Patients will be evaluated in 2 parts. Part A patients will be selected using a flow cytometric assay that quantifies intratumoral PD-1hiCD8+CTLA4+ "exhausted" lymphocytes in the tumor. Part B will enroll patients who have or are failing pembrolizumab at least 12 weeks after starting Programmed cell death protein 1 (PD-1) antibody alone or in combination, or, who have been selected using a flow cytometric assay that quantifies intratumoral PD-1hiCD8+CTLA4+ "exhausted" lymphocytes in the tumor.
