Clinical Trial Summary

This is a phase II multicenter study including breast cancer patients with chest wall disease that is hormone resistant (estrogen receptor (ER) positive/progesterone receptor (PR) positive/human epidermal growth factor receptor 2 (HER2) negative breast cancer with progressive disease on 2 prior lines of hormonal therapy) or triple negative (ER negative/PR negative/HER2 negative, TNBC). Eighty-four patients will be enrolled at Translational Breast Cancer Research Consortium (TBCRC) sites and will be randomized 2:1 to receive treatment with pembrolizumab and carboplatin (n=56, Arm A) or carboplatin alone (n=28, Arm B) until documented disease progression. Patients randomized to Arm B may cross-over following progression to pembrolizumab with or without carboplatin at investigator's discretion (Arm Bx). Patients may have received any number of prior lines of chemotherapy. Patients in Arm A will be treated with pembrolizumab 200 mg IV and carboplatin area under curve (AUC) 5 IV every 3 weeks for at least 6 cycles followed by maintenance pembrolizumab 200 mg IV every 3 weeks if stable or responding disease. Patients in Arm B will be treated with carboplatin AUC 5 IV every 3 weeks until progression, whereupon they may cross-over to pembrolizumab 200 mg IV every 3 weeks with or without carboplatin at investigator's discretion (Arm Bx). An interim analysis for futility will be performed after 18 patients are enrolled into Arm B to allow early stopping of that trial arm for lack of efficacy. The primary endpoint is to compare disease control rates at 18 weeks of treatment. Secondary endpoints include progression free survival, toxicity, and overall response rate.

Description:

There will be a companion translational study operating concurrently with the study described above. In this study, biomarker research to be performed on tumor biopsies and peripheral blood samples will be performed to explore the immunologic and genomic mechanism of action underlying treatment with pembrolizumab and carboplatin versus carboplatin alone. This protocol includes tissue and blood correlative exploratory endpoints including changes in tumor PD-L1 (programmed death ligand 1) gene expression, tumor and peripheral blood immune composition and cytokine expression, plasma tumor DNA, circulating tumor cells, and tumor myelocytomatosis (MYC) oncogene expression using tumor biopsy and peripheral blood testing before and after treatment; correlations with these markers and disease control rate will be assessed.
