NCT03735290

Brief Summary

Patients in the Phase 1b part of the study will be treated with ilixadencel at an increasing dose and frequency, in combination with standard doses and schedules of checkpoint inhibitor (CPI) pembrolizumab. The Phase 1b study will determine the optimal dose and schedule of ilixadencel. Patients in the Phase 2 part of the study will be randomly assigned to receive either ilixadencel (at the dose determined in Phase 1b) combined with the CPI, or only the CPI. Note: Recruitment to Phase 1b of the study has been completed.
