Summary

This trial is testing a new drug for age-related macular degeneration. There are 4 groups of patients, each taking different doses of the drug or a placebo. The trial will last 104 weeks, with follow up 30 days after the last dose.

Who is the study for?
This trial is for individuals with a condition called Geographic Atrophy (GA) that's due to Age-Related Macular Degeneration (AMD). Participants must have received a specific vaccination, be able to consent, and have GA lesions outside the central part of their retina. People are excluded if they've had other treatments or studies for GA in the last 3 months, have complement deficiencies, certain medical conditions deemed risky by the investigator, previous stem cell/gene therapy for eye conditions, active ocular diseases affecting vision assessment or allergies to study drug components.Check my eligibility
What is being tested?
The study tests different doses of Danicopan (100 mg twice daily, 200 mg twice daily, and 400 mg once daily) against a placebo to see which is more effective and safe over two years. It aims to find out how well Danicopan works on GA secondary to AMD and monitors participants' reactions over time after taking it.See study design
What are the potential side effects?
While specific side effects aren't listed here, common ones may include allergic reactions like rashes or itching due to hypersensitivity; potential risks could also involve issues related to immune response given Danicopan targets complement pathways involved in inflammation.

Trial Design

4Treatment groups
Experimental Treatment
Placebo Group
Group I: Danicopan: 400 mgExperimental Treatment1 Intervention
Participants will receive danicopan 400 mg qd during the masked Treatment Period. Once the optimal dose is identified, participants who have at least 52 weeks of treatment will be switched to the optimal dose for the remainder of the study.
Group II: Danicopan: 200 mgExperimental Treatment1 Intervention
Participants will receive danicopan 200 mg bid during the masked Treatment Period. Once the optimal dose is identified, participants who have at least 52 weeks of treatment will be switched to the optimal dose for the remainder of the study.
Group III: Danicopan: 100 mgExperimental Treatment1 Intervention
Participants will receive danicopan 100 mg bid during the masked Treatment Period. Once the optimal dose is identified, participants who have at least 52 weeks of treatment will be switched to the optimal dose for the remainder of the study.
Group IV: PlaceboPlacebo Group2 Interventions
Participants will receive matching placebo and will be re-randomized to one of the active treatment groups at Week 52, or to the optimal dose, if already identified.

Other Research
Common treatments for Age-Related Macular Degeneration (AMD) include complement inhibitors like Danicopan, which target the complement system to reduce inflammation and tissue damage associated with geographic atrophy. Anti-VEGF therapies are also widely used to inhibit abnormal blood vessel growth and leakage in the retina. These treatments are essential for slowing disease progression and preserving vision, thereby improving the quality of life for AMD patients.
