Study name A study of danicopan in participants with geographic atrophy secondary to age‐related macular degeneration
Methods Phase 2, controlled, randomised, double‐blind, parallel group study at multiple centres
Participants Adults 60 years and older with GA due to AMD in at least one eye. Participants with prior history of intravitreal anti‐vascular endothelial growth factor therapy and a known/suspected complement deficiency are excluded
Interventions Danicopan administered as an oral tablet at 100 mg twice a day, 200 mg twice a day, or 400 mg four times a day, as compared to placebo oral tablet at an equivalent frequency of administration
Outcomes Primary outcome measure:
  • Change from baseline in the square root of total GA lesion area in the study eye as measured by FAF (time frame: 52 weeks)


Secondary outcome measures:
  • Change in the square root of total GA lesion area in the study eye as measured by FAF (time frame: 104 weeks)

  • Change in the total GA lesion area in the study eye as measured by FAF (time frame: 52 and 104 weeks)

  • Change in monocular BCVA scores in the study eye as assessed by the ETDRS chart (time frame: 52 and 104 weeks)

  • Change in monocular LLVA scores in the study eye as assessed by the ETDRS chart (time frame: 52 and 104 weeks)

  • Change from baseline in LLD in the study eye (time frame: 52 and 104 weeks)

  • Change in monocular reading speeds in the study eye (time frame: 52 and 104 weeks)

  • Plasma concentration of danicopan over time (time frame: 4 hours post‐dose)

  • PD biomarkers, ex vivo serum alternative pathway activity, and plasma Bb concentration over time (time frame: 4 hours post‐dose)

  • Change in VFQ‐25 scores (time frame: 52 and 104 weeks)

  • Incidence of treatment‐emergent, serious, and ocular AEs, and clinical laboratory abnormalities, and events leading to discontinuation of study drug (time frame: 104 weeks)
