Summary

This is a multicenter, two part (Part A and Part B) clinical study of CMP-001 administered intratumorally (IT) and subcutaneously (SC) in combination with atezolizumab with or without radiation therapy in participants with NSCLC.

Detailed description

Former Sponsor Checkmate Pharmaceuticals This study will be conducted in two parts, run sequentially: Part A of the study will evaluate the safety and preliminary signs of efficacy for the combination of CMP-001 and atezolizumab. Part B of the study will evaluate the addition of radiation therapy to the combination of CMP-001 and atezolizumab. Each part of the study will follow a Simon 2-stage Optimal Design approach. Part A and Part B of the study will commence with a safety run in of 5 participants treated with the combination treatment (CMP-001 and atezolizumab in Part A; and CMP-001, atezolizumab and radiation therapy in Part B). After the first 5 participants have passed a safety dose-limiting toxicity (DLT) observation period of 30 days and upon approval from the Safety Review Committee (SRC), both parts of the study will continue with enrollment of an additional 7 participants in each part to complete Stage 1 of respective parts. If an acceptable safety profile is established and at least 2 responders out of 12 evaluable participants (that is, complete and partial responders based on Response Evaluation Criteria in Solid Tumors \[RECIST\] version 1.1 \[v1.1\] or RECIST v1.1 for immune-based therapeutics \[iRECIST\] criteria) in Stage 1), the study will enroll an additional 23 evaluable participants in Stage 2 of each part. A maximum of 35 evaluable participants will be enrolled in each Part A and Part B. Participants enrolled in Part A with documented progression per RECIST v1.1 on the combination of CMP-001 and atezolizumab have the option to receive radiation therapy add-on treatment after documented disease progression per computed tomography (CT)/magnetic resonance imaging (MRI) or positron emission tomography (PET) scan. The total number of participants enrolled into the Part A optional radiation therapy add-on may not exceed the total number of participants enrolled in Part A. Enrollment of participants in Part A optional radiation therapy add-on will not affect enrollment in Part B of the study as these participants will be evaluated separately. Participants will continue treatment with CMP-001 in combination with atezolizumab as long as they do not experience unacceptable toxicities and when, according to the Investigator, continued treatment is in the participant's best interest.
