Measure
Pembrolizumab Plus BL-8040
In cycle 1, BL8040 was administered1.25 mg/kg s.c. daily on days 1-5 and days 8-12. Starting with the second cycle pembrolizumab was administered on day1 (200 mg) and BL8040 was continued on days 1,4,8, and 11. Biopsy: Pretreatment biopsies; An optional biopsy after cycle 1 (BL monotherapy) and a second mandatory biopsy after cycle 3.
