Study Endpoints

Primary Endpoints

Number of Participants With Reduction of 17-hydroxyprogesterone to </= 2 Times the Upper Limit of Normal at Any Time Following 2 Weeks of Dosing With ATR-101
Evaluated at baseline and day 15 of each dose level. Each subject will have up to 5 dose levels.

17-hydroxyprogesterone was measured predose in the morning at the beginning and end of each dose level.

Frequency of dose-limiting toxicity and determination of maximum tolerated dose
Occurrence of DLT at 28 days

Adverse events will be recorded and tabulated by grade and system organ class according to CTCAE v 4.03. Laboratory measures and ECGs will be assessed.

Secondary Endpoints

Area under the plasma concentration versus time curve (AUC) of ATR-101
Day 1 and Day 22
Change in plasma cortisol levels
Baseline and day 22
Change in objective measurement of tumor size
