A Phase 2 Randomized, Double-Blind, Placebo-Controlled Study of ATR-101 for the Treatment of Cushing's Syndrome

This is a Phase 2 multicenter, randomized, double-blind, placebo controlled study of ATR-101
to evaluate the efficacy and safety of orally-administered ATR-101 in adults with endogenous
Cushing's syndrome. Following wash-out (if needed), all eligible subjects will enter an
open-label intra-subject dose-escalation period of 8 weeks' duration, followed either by a
double-blind randomized withdrawal period of 4 weeks' duration (if the subject meets
randomization criteria) or by an additional open label dosing period of 4 weeks' duration (if
the subject does not meet randomization criteria).It is anticipated that the overall duration
of the study per subject will range from approximately 16-22 weeks.

Inclusion Criteria:

- Confirmed diagnosis of endogenous Cushing's syndrome

- Baseline UFC 1.3 to 10 × upper limit of normal (ULN)

- If previous pituitary surgery, participants must be at least 3 months since surgery at
the time of screening

- BMI between 18 and 60 kg/m2, inclusive

Exclusion Criteria:

- Pseudo-Cushing's syndrome, cyclic Cushing's syndrome or current iatrogenic Cushing's
syndrome

- Candidates for surgical treatment of Cushing's syndrome, unless surgery is not
anticipated to occur during the study

- Normal late night salivary cortisol or 24-hr urine free cortisol

- Radiotherapy of the pituitary within 6 months
