PRIMARY outcome

Timeframe: 7 visits over a total duration of approximately 28 weeks

Population: One (1) subject was randomized, but not treated due to the enrollment cap being met, resulting in a total of 361 subjects in the Safety Set, comprised of 144 subjects (100.0%) in the LNZ101 treatment group, 144 subjects (100.0%) in the LNZ100 treatment group, and 73/74 subjects (98.6%) in the Vehicle treatment group.

Number and Percentage of Participants with at least one Treatment-Related Treatment-Emergent Adverse Events (TEAE) were collected by systematic assessment and coded using MedDRA.
