Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with Treatment-emergent adverse event (TEAE) as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 5.0	To evaluate safety of tildacerfont in participants with CAH as measured by number of subjects with adverse events following dosing by CTCAE version 5.0	12 weeks
Secondary	Proportion of participants who achieve a reduction in androstenedione (A4) or reduction in glucocorticoid (GC) dosing	To determine the efficacy of tildacerfont on disease control or reduction of GC use in participants with classic CAH as measured by number of subjects who achieve a reduction in A4 or reduction in GC dosing during treatment period	4 weeks or 12 weeks
Secondary	Proportion of participants with elevated baseline A4 who achieve a reduction in A4	To determine the efficacy of tildacerfont on disease control in participants with classic CAH measured by the number of participants with elevated baseline A4 who achieve reduction in A4 at week 4	4 weeks
Secondary	Proportion of participants with elevated baseline A4 who achieve a reduction in A4 who achieve A4 normalization	To determine the efficacy of tildacerfont on disease control in participants with classic CAH measured by the number of participants with elevated baseline A4 who achieve reduction in A4 at week 4 or week 12	4 weeks or 12 weeks
Secondary	Tildacerfont pharmacokinetics (PK)	To determine the consistency of preliminary tildacerfont PK in participants with those simulated in a PBPK model measured by comparing tildacerfont plasma concentrations with current PBPK simulation for consistency	4 weeks or 12 weeks
