A Phase I Study of GenSci148 Intravitreal Injection for Neovascular Age-related Macular Degeneration, Diabetic Macular Edema and Retinal Vein Occlusion (GenSci148-101)

A Phase I, Open-label, Dose-escalation, Multicenter Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of a Single Intravitreal Injection of GenSci148 in Participants With Neovascular Age-related Macular Degeneration (nAMD) and Multiple Intravitreal Injections of GenSci148 in Participants With nAMD, Diabetic Macular Edema (DME) and Retinal Vein Occlusion (RVO)

This is a Phase I, multicenter, open-label, dose-escalation study conducted in two parts to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GenSci148 administered via intravitreal (IVT) injection in participants with neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO). Part 1 evaluates single ascending doses in nAMD participants. Part 2 evaluates multiple doses in nAMD, DME, and RVO participants. The study also assesses immunogenicity and explores preliminary efficacy.

详细说明

This is a Phase I, multicenter, open-label, dose-escalation study conducted in 2 parts to evaluate the safety, tolerability, PK and PD profiles, and immunogenicity, as well as the preliminary efficacy of intravitreal injection of GenSci148 in participants with nAMD, DME and RVO.

Part 1 (Single Ascending Dose, SAD): Conducted in participants with nAMD. Four dose levels (1 mg/eye, 3 mg/eye, 7 mg/eye, and 10 mg/eye) are planned, administered via a single IVT injection. Dose escalation is determined by the Safety Review Committee (SRC) based on safety, tolerability, PK, PD, and other available data.

Part 2 (Multiple Ascending Dose, MAD): Conducted in participants with nAMD, DME, and RVO. Three dose levels (low, medium, and high) are planned. Participants will receive multiple IVT injections according to the study schedule. Disease activity assessment will be performed during follow-up, and participants meeting retreatment criteria may receive additional doses of GenSci148.

Safety assessments include adverse events, physical examinations, laboratory tests, vital signs, ECG, and ophthalmic examinations (BCVA, IOP, slit-lamp examination, , etc.). PK/PD and immunogenicity samples are collected at predefined time points.
