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.

In three double-blind, vehicle-controlled clinical trials (Trial 1, and Trial 2 and Trial 3, which were similarly designed to Trial 1), 1596 adult and pediatric subjects were treated with ZELSUVMI or vehicle gel topically once daily for up to 12 weeks [see Clinical Studies (14) ].

In these trials 3% of subjects were less than 2 years of age, and 96% of subjects were 2 to 17 years of age.

The trial population included 51% male, 88% White, 6% Black, and 6% Other;

for ethnicity, 21% of subjects identified as Hispanic/Latino, 78% as non-Hispanic/Latino, and 1% were not reported.

Adverse reactions reported by ≥1% of subjects and more frequently than vehicle-treated subjects are listed in Table
