Registration Number
NCT04115306
Lead Sponsor
Phoenix Molecular Designs
Brief Summary

The purpose of this study is to test the safety and tolerability of PMD-026 in patients with metastatic breast cancer. PMD-026 is a targeted oral agent designed to kill tumor cells in metastatic breast cancer.

Detailed Description

Combination with fulvestrant (Part 3):

This study will prospectively enroll RSK2+, HR+, and human epidermal growth factor receptor 2 negative (HER2-) patients to evaluate PMD-026 in combination with a standard dose and schedule of fulvestrant. Fulvestrant will be dosed per the package insert in combination with PMD-026 at the RP2D determined in the monotherapy phase of the study. Up to 20 patients will be enrolled with locally advanced or metastatic HR+/HER2- breast cancer previously treated with a CDK4/6 inhibitor in combination with endocrine therapy.
