Study Details

Study Description

Brief Summary

CMP-001-009 is a Phase 2 study of intratumoral CMP-001 in combination with an intravenous PD-1-blocking antibody administered to participants with certain types of advanced or metatastic cancer.

The primary objective of the study is to determine the Investigator-assessed confirmed objective response with CMP-001 in combination with a programmed cell death protein (PD-1)-blocking antibody in subjects with certain types of advanced or metatastic cancer.

The secondary objectives are to:
  • To evaluate the safety and tolerability of CMP-001 administered by intratumoral (IT) injection in combination with a PD-1-blocking antibody in study subjects.

  • To evaluate the efficacy of CMP-001 in combination with a PD-1-blocking antibody in study subjects.

Participants will continue to receive treatment of CMP-001 in combination with a PD-1-blocking antibody according to the treatment schedule until a reason for treatment discontinuation is reached.

  • Outcome Measures

    Primary Outcome Measures

    1. Objective response rate (ORR) with CMP-001 in combination with a programmed cell death protein 1 (PD-1)-blocking antibody (cemiplimab-rwlc) in study subjects with metastatic or advanced/unresectable CSCC, MCC, or TNBC [From first dose of CMP-001 (Week 1 Day 1) until 30 days after the last CMP-001 injection (until a reason for treatment discontinuation occurs)]

      CSCC is defined as cutaneous squamous cell carcinoma, MCC is defined as Merkel cell carcinoma, and TNBC is defined as triple negative breast cancer. ORR is further defined as the proportion of subjects with a confirmed objective response of complete response (CR) or partial response (PR) based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).

    Secondary Outcome Measures

    1. Safety and tolerability of CMP-001 administered by intratumoral (IT) injection in combination with a PD-1-blocking antibody (cemiplimab-rwlc) in the study subjects [From first dose of CMP-001 (Week 1 Day 1) until 30 days after the last CMP-001 injection (until a reason for treatment discontinuation occurs)]

      Safety and tolerability is defined as the presence of Adverse events (AEs), serious adverse events (SAEs), and AEs leading to discontinuation or death, and severity of AEs as assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE v5.0)

    2. Efficacy of CMP-001 in combination with a PD-1-blocking antibody (cemiplimab-rwlc) in the study subjects [From first dose of CMP-001 (Week 1 Day 1) until 30 days after the last CMP-001 injection (until a reason for treatment discontinuation occurs)]

      Efficacy is measured by: Duration of response (DOR), defined as the time from date of first documented response (CR or PR) to date of documented progressive disease (PD), based on RECIST v1.1 Immune ORR, DOR, and progression-free survival (iORR, iDOR, and iPFS) based on immunotherapy Response Evaluation Criteria in Solid Tumors (iRECIST) treatment response in noninjected target lesions based on RECIST v1.1. Response in injected and noninjected target lesions per RECIST v1.1. Progression-free survival (PFS), defined as the time from date of first dose of study treatment to date of documented PD based on RECIST v1.1 or death, whichever occurs first. Overall survival (OS), defined as the time from date of first dose of study treatment to date of death
