a phase i clinical trial of bat5906 injection in patients with wet age-related macular degeneration

Conditions: Age-related Macular Degeneration

Summary: a phase i clinical trial for bat5906(single-dose;for injection) on safety and pharmacokinetics for patients with age-related macular degeneration.

the primary objective: to evaluate the safety and pharmacokinetics of bat5906 (single-dose ophthalmic intracireal iinjection) in patients wamd , when the injection dosage escalates. the secondary objective: to evaluate the immunogenicity profile of bat5906; to evaluate the pharmacodynamics and therapeutic efficacy profile of bat5906.
