Brief Summary:

CMP-001-002 is a Phase 1b study of CMP-001 administered to participants with advanced melanoma who are either receiving pembrolizumab, or who have previously received an anti-programmed cell death protein 1 (anti-PD-1)/programmed death-ligand 1 (PD-L1) therapy for advanced melanoma, and who have not responded (that is, immunotherapy resistant).

This study will be conducted in two parts:

Part 1 will consist of a Dose Escalation Phase and a Dose Expansion Phase

  • Dose Escalation Phase will be conducted to assess and identify a recommended phase 2 dose (RP2D) of CMP-001 for subcutaneous (SC) administration
  • The Dose Expansion Phase is intended to further characterize the safety, pharmacodynamics, and preliminary evidence of antitumor activity of the RP2D of CMP-001 administered SC in combination with pembrolizumab

Part 2 will assess the safety and preliminary evidence of antitumor activity of CMP-001, administered both SC and intratumoral (IT) when given in combination with pembrolizumab.

Participants will continue treatment with CMP-001 in combination with pembrolizumab as long as they do not experience unacceptable toxicities and when continued treatment, is in the participant's best interest according to the Investigator.

  • Any concurrent uncontrolled illness, including mental illness or substance abuse, which in the opinion of the Investigator, would make the participant unable to cooperate or participate in the trial.
  • Severe uncontrolled cardiac disease within 6 months of screening, including but not limited to uncontrolled hypertension; unstable angina; myocardial infarction (MI) or cerebrovascular accident (CVA).
  • Requires prohibited treatment that is, non-protocol specified anticancer. pharmacotherapy, surgery or conventional radiotherapy for treatment of malignant tumor)
  • Women of child-bearing potential who are unable or unwilling to use an acceptable method of contraception.
