- Objective Response Rate (ORR) [ Time Frame: At 13 weeks ]The proportion of subjects with the best response of complete response (CR), or partial response (PR) per Response Evaluation Criteria for Solid Tumors (RECIST 1.1). Per RECIST 1.1 , CR is defined as all target lesions gone; PR is defined as a > 30% decrease in size of lesion from baseline.
- Progression-Free Survival (PFS) [ Time Frame: up to 4 years ]The length of time during and after study treatment that a patient remains alive without worsening disease. Per RECIST 1.1, progression is defined as a > 20% increase from smallest sum of longest (lesion) diameter recorded since treatment started (best response - target lesions) and/or, enlargement of non-target lesions.
- Change in number of CD8+ cells [ Time Frame: At baseline (pre-treatment) and at 8 weeks (after the start of treatment) ]Within-patient changes in number of CD8+ cells present in tumor tissue and peritoneal fluid.
- Change in number of CD3+ cells [ Time Frame: at baseline (pre-treatment) and at 12 weeks (after the start of treatment) ]Within-patient changes in number of CD3+ cells present in tumor tissue and peritoneal fluid.
- NK Cells [ Time Frame: at baseline (pre-treatment) and at 12 weeks (after the start of treatment) ]
- Grandzyme B [ Time Frame: at baseline (pre-treatment) and at 12 weeks (after the start of treatment) ]
- CD4 Tbet [ Time Frame: at baseline (pre-treatment) and at 12 weeks (after the start of treatment) ]
