The purpose of phase 1 is to determine safety, tolerability and pharmacokinetics (PK) of H3B-6545 in women with locally advanced or metastatic estrogen receptor (ER)-positive, human epidermal growth factor 2 (HER2)-negative breast cancer.
The purpose of phase 2 is to estimate the efficacy of H3B-6545 in terms of best overall response rate, duration of response (DoR), clinical benefit rate (CBR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) in all participants with ER-positive, HER2-negative breast cancer and in those with and without ER alpha mutation [including a clonal estrogen receptor 1 gene (ESR1) Y537S mutation].
