Hormone Receptor Positive Malignant Neoplasm of Breast
Conditions
Brief summary
The primary purpose of this study is to evaluate the clinical safety profile, tolerability, and pharmacokinetic (PK) characteristics of RAD140 in hormone receptor positive breast cancer.
Detailed description
This is a first in humans study that is designed to evaluate the clinical safety profile, tolerability, and pharmacokinetic (PK) characteristics of RAD140 in hormone receptor positive breast cancer.
Interventions
RAD140 will be supplied as formulated drug-in-capsules for oral administration.
