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.

The safety of SEPHIENCE was evaluated in Trial 1 [Part 1 (open label); Part 2, (placebo-controlled)]; and Trial 2 (open-label).

The two trials included a total of 215 SEPHIENCE-treated patients with PKU: 10 (5%) were <2 years old, 118 (55%) were ≥2 and <17 years old, and 87 (40%) were ≥17 years old.

All patients received SEPHIENCE from 7.5 mg/kg/day up to 60 mg/kg/day and the median duration of treatment (in weeks) was 25.5 [see Clinical Studies ( 14.1 )] .

Trial 1 Trial 1 included a total of 157 patients (85 male and 72 female, aged 1 year to 61 years old) with PKU across both parts of the trial.

The patients received dosages from 20 mg/kg up to 60 mg/kg daily and the median duration of treatment was 8 weeks.

Table 4 lists the most common adverse reactions that were reported in ≥2% of patients treated with SEPHIENCE and greater than that of the placebo group in Part 2 of Trial 1.

Table 4: Adverse Reactions for SEPHIENCE in Adult and Pediatric Patients with PKU that Occurred in ≥2% of Sepiapterin-Treated Patients and Greater than Placebo (Trial 1 Part 2) a Includes Abdominal pain; Abdominal pain upper, Abdominal discomfort.

Description of Selected Adverse Reactions Increased Bleeding In Trial 1 Part 2, a case of heavy menstrual bleeding was reported in a SEPHIENCE-treated patient.

Less than 2% of patients in Trial 2 experienced increased bleeding, which included heavy menstrual bleeding, non-traumatic superficial hematomas, and prolonged bleeding.

Hypophenylalaninemia In Trial 1 Part 2, hypophenylalaninemia was seen in 5% (2/37) of sepiapterin-treated pediatric patients and in no adult patients.

Some pediatric patients in Trial 2 had multiple low blood Phe levels.
