Clinical Trial Summary

The purpose of this study is to find out the possible anti-cancer effect of pelareorep in combination with chemotherapy [paclitaxel] and avelumab in treating a type of breast cancer called Hormone Receptor positive (HR+)/Human Epidermal Growth Factor Receptor 2 negative(HER2-) breast cancer, which is either locally advanced or has metastasized (cancer that has spread in your body). The study will investigate if pelareorep in combination with paclitaxel and avelumab is more effective than paclitaxel alone, or pelareorep and paclitaxel. The safety of the combination treatments will also be evaluated.


Clinical Trial Description

This is an open-label randomized Phase 2, 3-cohort study to evaluate the safety and efficacy of pelareorep, paclitaxel and avelumab in Hormone Receptor+ (HR+)/Human Epidermal Growth Factor Receptor 2 negative (HER2-) with endocrine-refractory metastatic breast cancer. Patients will be randomized to one of three treatment cohorts: paclitaxel alone, pelareorep + paclitaxel, or pelareorep + paclitaxel + avelumab. A three patient safety run-in will be conducted in the cohort for pelareorep + paclitaxel + avelumab prior to beginning randomization into all three cohorts. Patients will give mandatory blood samples and optional tumor biopsies, which will be analyzed for biomarkers to determine the immunological changes within the tumor microenvironment and peripheral blood in patients treated with paclitaxel alone, in combination with pelareorep, and in combination with pelareorep and avelumab. ;
