What researchers measure

Primary outcomes

  1. Safety: incidence of treatment emergent adverse events (TEAEs), vital signs, physical exam, ocular exams, electrocardiogram, ocular symptoms, laboratory tests on whole blood, serum and urine.

    Time frame: 28 days of treatment: visit 1 (screening), visit 2 (eligibility), visit 3 (randomization) visit 4 (Day 14), visit 5 (Day 28)

Secondary outcomes

  1. Composite of Pharmacokinetics

    Time frame: 28 days: visit 3 (randomization); visit 4 (Day 14) ; visit 5 (Day 28)

  2. Efficacy: measurement of change in intraocular pressure from baseline.

    Time frame: 28 days: visit 1 (screening); visit 2 (eligibility) ; visit 3 (randomization) , visit 4 (Day 14) ; visit 5 (Day 28)
