INCMGA00012 and Pelareorep for the Treatment of Metastatic Triple Negative Breast Cancer, IRENE Study
Study Details
Study Description
Brief Summary
This is a phase 2 study to evaluate the safety and efficacy of the combination of INCMGA00012 and pelareorep and to see how well they work in treating patients with triple negative breast cancer that has spread to other parts of the body (metastatic).
INCMGA00012 is a monoclonal antibody that works by attaching to the programmed cell death protein 1 (PD-1) and blocking this pathway, allowing the immune system to recognize and attack the cancer cells. Pelareorep is a type of virus called reovirus which occurs naturally and may break down cancer cells. Giving INCMGA00012 and pelareorep may slow the growth and spread of the cancer to another part of the body.

Detailed Description
PRIMARY OBJECTIVES:
-
To determine the efficacy of the combination of retifanlimab (INCMGA00012) and pelareorep for patients with metastatic triple negative breast cancer in the second and third line setting.
-
To assess the safety, tolerability and feasibility of INCMGA00012 in combination with the oncolytic virus pelareorep for patients with metastatic triple negative breast cancer in the second and third line setting.
SECONDARY OBJECTIVES:
-
To assess progression free survival (PFS), overall survival (OS) and duration of response (DOR) in patients receiving INCMGA00012 in combination with the oncolytic virus pelareorep for patients with metastatic triple negative breast cancer in the second and third line setting.
-
To assess quality of life measures.
EXPLORATORY OBJECTIVES:
-
To assess whether pre-treatment PD-L1 expression is associated with treatment outcomes.
-
To determine if changes in T cell repertoire as measured by T-cell receptor (TCR) sequencing is predictive of treatment outcomes.
OUTLINE:
Patients receive pelareorep intravenously (IV) over 60 minutes on days 1, 2, 15, and 16. Patients also receive retifanlimab IV over 60 minutes on day 3. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 and 90 days, then every 6 months for up to 2 years.

Outcome Measures
Primary Outcome Measures
- Objective response rate (ORR) [Within 8 weeks after completion of treatment]
Defined as the percentage of participants having an objective response (complete response [CR] or partial response [PR]), according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. The ORR of the drug will be assessed according to Simon's two stage design. The estimated ORR will be compared to the response rate specified in the null hypothesis (6%) using one-sided exact binomial test at type I error 5%. 95% confidence interval (C.I.) will be also reported.
- Incidence of adverse events [Up to 2 years after completion of treatment]
Will be determined by the number, frequency, duration, and severity of adverse events (AEs) using Common Terminology Criteria for Adverse Events (CTCAE) v 5.0; laboratory tests and vital signs.
Secondary Outcome Measures
- Progression free survival (PFS) [From the start of therapy until disease progression, or death due to any cause, assessed up to 2 years after completion of treatment]
Will be determined by the immune complete response (iCR). Will be estimated using Kaplan-Meier product-limit method. The median PFS times with two-sided 95% CIs will be estimated.
- Overall survival (OS) [From the start of therapy until death due to any cause, assessed up to 2 years after completion of treatment]
Will be estimated using Kaplan-Meier product-limit method. The median OS times with two-sided 95% CIs will be estimated.
- Duration of Response (DOR) [Up to 2 years after completion of treatment]
Defined as the time from an initial objective response (CR or PR) according to RECIST v 1.1 until disease progression, or death due to any cause, as determined by iCR.
- Quality of life will be evaluated by European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-Core 30 (C30). [Up to 2 years after completion of treatment]
Other Outcome Measures
- Changes in PD-L1 expression [Pre and post-treatment]
Will be correlated with treatment response.
- T-cell receptor (TCR) sequencing [Up to 2 years after completion of treatment]
Assess the role of TCR sequencing in predicting treatment response.
