简要总结
Evaluation of safety and efficacy of PL9643 Ophthalmic Solution compared to placebo for the treatment of the signs and symptoms of dry eye.
详细描述
The clinical trial is a Phase 2, multi center, randomized, double masked and placebo controlled study.
During a 14-day study run-in period (for the purpose of subject selection) prior to randomization, all subjects will receive Placebo Ophthalmic Solution (vehicle) bilaterally. During the screening period, exposure to the CAE® will be conducted to ascertain eligibility to enter the study at Visit 1 and Visit 2. Those who qualify at Visit 2 will be randomized to receive study drug in a double-masked fashion for 12 weeks. The CAE® exposure will occur at all Visits.
