Arms and Interventions

Arm Intervention/Treatment
Placebo Comparator: Placebo

Drug: Placebo
Placebo is administered once daily or three times daily.

Experimental: KHK4951

KHK4951 is administered once daily or three times daily.

Outcome Measures

Primary Outcome Measures

  1. Number of participants with adverse events [Day 1 to Day 43]

    For adverse events that occurred after administration of the investigational drug, number of subjects with AEs and occurrence frequency are evaluated.

Secondary Outcome Measures

  1. Serum KHK4951 concentration [Healthy Volunteers: Day 1, Day2, Day4, Day8, Day12, Day16, Day21, Day23, Day 25, Day 29, Day 36, Day 43; Patients: Day 1, 8, 22, 43]

  2. Time to the maximum concentration [Day 1 to Day 43]

  3. The maximum concentration [Day 1 to Day 43]

  4. Area under the concentration-time curve [Day 1 to Day 43]

  5. Apparent clearance [Day 1 to Day 43]

  6. Elimination half-life [Day 1 to Day 43]

  • Glaucoma

  • Ischemic optic neuropathy

  • Retinitis pigmentosa

  • Current or history of vitreous hemorrhage or macular hole in the study eye

  • Any abnormality in the anterior segment of the eye or vitreous body that may affect fundus observation by OCT, color fundus photography, or fluorescein angiography
