Официальное название
A Phase I/IIa Trial to Evaluate the Safety, Tolerability and Efficacy After Single Administration of TO-O-1007 (Intravitreal Implant) in Subjects With Geographic Atrophy (GA) Secondary to Age-related Macular Degeneration (AMD)
Обзор
This study will evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of TO-O-1007, a biodegradable sustained-release intravitreal implant, for the treatment of Geographic Atrophy (GA) secondary to Age-related Macular Degeneration (AMD). A long-acting intravitreal implant providing sustained delivery of API over 6 months may slow the progression of GA lesions while reducing treatment burden associated with frequent intravitreal injections. TO-O-1007 may offer a convenient treatment option with the potential to preserve retinal structure and visual function while maintaining an acceptable safety profile.
Подробное описание
TO-O-1007 is a biodegradable sustained-release intravitreal implant, that is injected into the vitreous cavity of the eye. The implant is designed to gradually degrade over time, providing sustained ocular delivery of API for up to 6 months following a single administration. By continuously inhibiting C3/C5 activation, TO-O-1007 is intended to slow the progression of Geographic Atrophy (GA) secondary to Age-related Macular Degeneration (AMD), with the goal of preserving retinal structure and visual function. In this study, TO-O-1007 will be evaluated for its safety, tolerability, pharmacokinetics, and preliminary efficacy to determine whether it may offer a durable treatment option that reduces treatment burden compared with currently available therapies requiring more frequent intravitreal injections.
Вмешательства
- Препарат TO-O-1007 (low-dose)
TO-O-1007 (low-dose): Participants will receive one TO-O-1007 implant administered by intravitreal injection into the study eye. - Препарат TO-O-1007 (high-dose)
TO-O-1007 (high-dose): Participants will receive two TO-O-1007 implants administered by intravitreal injection into the study eye. - Процедура Sham injection
Sham injection: No injection is given. It is a sham injection to keep the participant masked.
