Macular Edema clinical trials at UCSF

This study will evaluate the efficacy, safety, and Pharmacokinetics (PK) of the PDS with ranibizumab in participants with DME when treated every 24 weeks (Q24W) compared with intravitreal (IVT) ranibizumab 0.5 milligrams (mg) every 4 weeks (Q4W). The substudy will evaluate safety of re-implanting the updated PDS with ranibizumab and the refill-exchange procedures following re-implantation in participants with DME who were previously enrolled in the main study, GR40550. Up to 100 participants from the main study will be enrolled and followed for a maximum of 72 weeks post-re-implantation in the substudy.

This study aims to evaluate the ocular and systemic safety, tolerability and efficacy of RO7446603 in participants with diabetic macular edema (DME). The study consists of 2 segments: Phase I (Parts 1-4) and Phase II (Part 5). Phase I investigated the safety of RO7446603 following a single and multiple intravitreal (IVT) doses as monotherapy or co-administered with IVT aflibercept or IVT faricimab (in separate injections). Phase II will investigate the safety, tolerability, pharmacokinetics (PK) and efficacy of two dose levels of RO7446603 in combination with faricimab, with the two drugs co-mixed and administered as a single IVT injection, compared to faricimab alone. The first participant was enrolled in the Phase I segment on June 22, 2022. Phase I has been completed.
