Brief Summary

The goal of this clinical study is to determine the safety, pharmacokinetics, pharmacodynamics and efficacy and activity of seviteronel, a lyase-selective inhibitor of CYP17, in patients with advanced breast cancer.

Detailed Description

This is an open-label, Phase 1/2 study of seviteronel in subjects with TNBC or ER +/HER2 normal unresectable locally advanced breast cancer. Only women will be enrolled in Phase 1 and both men and women enrolled into their respective cohorts in Phase 2. There will be a dose confirmation Phase 1 portion of the study to establish the recommended Phase 2 dose (RP2D) for women with breast cancer using a non-stratified, combined cohort of women with TNBC or ER+ BC. Cohort expansion will occur in Phase 2 at the RP2D confirmed/established in Phase 1 using separate TNBC and ER+ cohorts. The Phase 2 portion of the study is divided into three parallel cohorts:

Cohort 1: Female TNBC Subjects Cohort 2: Female ER+ Subjects Cohort 3: Male ER+ BC or TNBC Subjects
