6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adults with Congenital Adrenal Hyperplasia ( CAH) The safety of CRENESSITY in adults was assessed in Study 1, a randomized, double-blind, placebo-controlled study of 182 adults aged 18 to 58 years with classic CAH due to 21-hydroxylase deficiency.
A total of 122 subjects received CRENESSITY 100 mg twice daily and 59 subjects received placebo twice daily for up to 24 weeks [see Clinical Studies ( 14.1 )] .
Adverse Reactions Leading to Discontinuation of Treatment A total of 3% of CRENESSITY-treated subjects and no placebo-treated subjects discontinued treatment because of adverse reactions of restlessness, apathy, dyspepsia, nausea, and vomiting.
Commonly Observed Adverse Reactions Adverse reactions that occurred in ≥4% of CRENESSITY-treated subjects and more frequently than in placebo-treated subjects are presented in Table 4 .
Table 4 : Adverse Reactions (≥4%) in Adults with Congenital Adrenal Hyperplasia Treated with CRENESSITY and Occurring More Frequently Than in Placebo-Treated Subjects Adverse Reactions CRENESSITY (N=122) % Placebo (N=59) % Fatigue 25 15 Headache 16 15 Dizziness 8 3 Arthralgia 7 0 Back pain 6 3 Decreased appetite 4 2 Myalgia 4 3 Suicidal Ideation and Behavior Study 1 excluded subjects with active suicidal ideation with intent or plan within the six months prior to screening and those with a history of suicidal behavior within the past year, based on the Columbia-Suicide Severity Rating Scale (C-SSRS) administered at screening.
The C-SSRS was administered to subjects at regular intervals during the study.
Three of 122 (2.5%) CRENESSITY-treated subjects reported suicidal ideation without method, intent or plan on the C-SSRS during the 24-week double-blind treatment period compared to 1 of 59 (1.7%) placebo-treated subjects.
One of the three subjects receiving CRENESSITY and the placebo-treated subject reported a lifetime history of suicidal ideation.
One CRENESSITY-treated subject without a history of suicidal ideation or behavior attempted suicide during the open-label period after 320 days of treatment.
Laboratory Findings Neutrophil count less than 2 x 10 3 cells/mcL occurred in 14% (17 of 120) of CRENESSITY-treated subjects, compared to 5% (3 of 58) of subjects in the placebo group.
Neutrophil count less than 1 x 10 3 cells/mcL occurred in 0.8% (1 of 120) of CRENESSITY-treated subjects, compared to 1.7% subjects (1 of 58) in the placebo group.
Pediatric Patients with Congenital Adrenal Hyperplasia The safety of CRENESSITY in pediatric patients was evaluated in Study 2, a randomized, double-blind placebo-controlled study of 103 pediatric subjects aged 4 to 17 years with classic CAH due to 21-hydroxylase deficiency.
Pediatric subjects were randomized to receive CRENESSITY twice daily (N=69) or placebo (N=34) for 28 weeks, using weight-based dosing (50 mg twice daily via oral solution for subjects 20 to <55 kg, or 100 mg twice daily via oral capsules for subjects ≥55 kg) [see Clinical Studies ( 14.2 )] .
Adverse Reactions Leading to Discontinuation of Treatment A total of 3% of CRENESSITY-treated subjects and no placebo-treated subjects discontinued treatment because of adverse reactions of abdominal pain, myalgia, and dizziness.
Commonly Observed Adverse Reactions Adverse reactions that occurred at an incidence of ≥4% in CRENESSITY-treated pediatric subjects (50 mg twice daily or 100 mg twice daily) and greater than placebo are presented in Table 5 .

Four of 67 (6%) CRENESSITY-treated subjects and 0 of the 31 (0%) placebo-treated subjects reported suicidal ideation without method, intent or plan on the C-SSRS during the 28-week double-blind treatment period.
Two of the four CRENESSITY-treated subjects reported a lifetime history of suicidal ideation.
There were no completed suicides or suicide attempts.
Laboratory Findings Neutrophil count less than 2 x 10 3 cells/mcL occurred in 37% (25 of 68) of CRENESSITY-treated subjects, compared to 16% (5 of 32) of subjects in the placebo group.
Neutrophil count less than 1 x 10 3 cells/mcL occurred in 4% (3 of 68) of CRENESSITY-treated subjects, compared to no subjects (0 of 32) in the placebo group.
( 6.1 ) Pediatric Patients: Most common adverse reactions (at least 4% for CRENESSITY and greater than placebo) are headache, abdominal pain, fatigue, nasal congestion, and epistaxis.
