A Study to Investigate the Safety, Tolerability, Pharmacokinetics (PK) and Pharmacodynamics (PD) of RO7497372 in Participants With Diabetic Macular Edema (DME)
Eye Disorder Diabetic Macular Edema
Basic Details
Sponsor
Genentech, Inc.
Phase
Phase 1
Trial Identifier
NCT06847854, BP44175
Condition
Diabetic Macular Edema
Official Title
A Phase I, Multipart, Multicenter Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of RO7497372 Following Intravitreal Administration in Participants With Diabetic Macular Edema (Part 1 Non-Randomized, Open-Label, Multiple Ascending Dose; Part 2 Randomized, Double-Masked)
Study Summary
This study will assess the safety and tolerability of RO7497372 in participants with DME. The study consists of 2 parts. Part 1 will test multiple-ascending doses of RO7497372 after unilateral intravitreal (IVT) administration in participants with DME. The main purpose of Part 1 is to provide data for RO7497372 safety and tolerability, as well as to characterize the ocular and systemic pharmacokinetics (PK), systemic anti-drug antibodies (ADA), and duration of target engagement, i.e., the pharmacodynamics (PD) in aqueous humor (AH) and blood. Part 2 will evaluate the safety, tolerability, PK, and PD of two dose strengths of RO7497372 (low dose and high dose), identified as safe and tolerated in Part 1.
