A Phase 3 Study to Evaluate the Efficacy and Safety of Intravitreal KSI-101 in Participants with Macular Edema Secondary to Inflammation (MESI)
A Phase 3 Study to Evaluate the Efficacy and Safety of Intravitreal KSI-101 in Participants with Macular Edema Secondary to Inflammation (MESI)
This study is open to adults 18 and older with an eye condition called diabetic macular edema. People are required to have a specific type of diabetic macular edema called centre-involved diabetic macular edema (CI-DME) to take part. The purpose of this study is to find out whether a medicine called BI 1815368 improves sight in people with CI-DME and to find the most suitable dose. This study has 2 parts. In the first part, participants are put into 2 groups of equal size randomly, which means by chance. One group takes BI 1815368 tablets and the other group takes placebo tablets. Placebo tablets look like BI 1815368 tablets but do not contain any medicine. In the second part, participants are put into 4 groups of equal size randomly. 3 groups take different daily doses of the study medicine, BI 1815368, while 1 group takes placebo. All participants take tablets twice a day for about 11 months. Participants are in the study for about 1 year. During this time, they visit the study site 16 times. At visits, doctors check the participant's vision and collect information on any health problems. They take detailed pictures of the eye. The changes over time are compared between the groups to see if the treatment works.
Phase 2 open label, randomized, active controlled, dose-ranging trial in adults with Center Involved - Diabetic Macular Edema (CI - DME)
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.
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.
A non-randomized study evaluating the safety of an orally administered inflammasome inhibitor, K9, for the treatment of diabetic macular edema (DME).
EYE-TIE-201 is a 2-part study to investigate the safety and effectiveness of a new drug being developed called EYE201. All participants in the study will receive a total of 3 injections of EYE201 into the study eye, spaced at 4 weeks apart. In the first part, termed the multiple ascending dose (MAD) portion of study, the safety of EYE201 will be assessed at increasing doses in branch retinal vein occlusion (BRVO) participants. Approximately 12 participants will be entered in this part of the study. In the second part of the study, called the dose finding part, 2 doses of EYE201 will be selected and their effectiveness will be compared. This portion of the study assesses the safety and preliminary efficacy of EYE201 in patients with diabetic macular edema (DME) or neovascular macular degeneration (NVAMD). Approximately 80 participants will be entered in this part of the study.
Patients with diabetic macular edema (DME) sometimes must undergo vitrectomy surgery (PPV) for diabetic and non-diabetic related issues. Patients may have improved DME with anti-VEGF therapy and ranibizumab has been found to reduce central macular thickness (CMT) with anti-VEGF therapy following vitrectomy. Those patients still require intravitreal injections but the pharmacokinetics of a vitrectomized eye are different than those eyes that have not undergone vitrectomy. The clearance of protein molecules is quicker in vitrectomized eyes so these patients may be more refractory to standard of care anti-VEGF therapy. In rabbit models, the half-life of both bevacizumab and ranibizumab were reduced by a factor 1.8 and 1.3, respectively, after pars plana vitrectomy. In a study examining intravitreal triamcinolone acetonide in human eyes, the half-life was found to be 18.6 days in non-vitrectomized eyes and 3.2 days in vitrectomized eyes, but there was considerable intrasubject variation. Patients with various disease states, including neovascular age-related macular degeneration (nAMD) have been managed with monthly anti-VEGF therapy successfully after vitrectomy surgery. Another study performed by the DRCR net showed that patients with DME treated with anti-VEGF are not affected in the long term if they had had a previous vitrectomy. High dose aflibercept may improve anatomic and visual outcomes in this patient population. Also, high dose aflibercept may allow for longer treatment intervals in these vitrectomized eyes.
Phase 2 study to assess the efficacy of topically administered eyedrops of INV-102 during a 12-week dosing period in subjects with non-center involved DME (NCIDME) associated with NPDR \[Part 1\] and during an 8-week dosing period in subjects with center-involved DME (CIDME) associated with NPDR \[Part 2\].
