Clinical Trial Summary

The purpose of this study is to evaluate the long-term safety and tolerability of intravitreal (ITV) injections of galegenimab (FHTR2163) administered every 4 weeks (Q4W) or every 8 weeks (Q8W) in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) who completed the parent study (NCT03972709/GR40973).

Recruitment information / eligibility

Eligibility

Inclusion Criteria:

• Completed the parent study (NCT03972709/GR40973) through the Week 76 visit without early treatment discontinuation

• Sufficiently clear ocular media, adequate pupillary dilation, and fixation to permit acceptable fundus imaging.

Ocular Inclusion Criteria: Study Eye - If the study eye best corrected visual acuity (BCVA) letter score is =69 letters (Snellen equivalent of 20/40 or better), the non-study eye must have a BCVA letter score of =44 letters (Snellen equivalent of 20/125 or better) on visit Day 1 of the open label extension (OLE)/Week 76 of parent study.

Ocular Inclusion Criteria: Non-Study Eye

• The non-study eye must have a BCVA letter score of =44 letters (Snellen equivalent of 20/125 or better) if the study eye BCVA letter score is =69 letters (Snellen equivalent of 20/40 or better) on visit Day 1 OLE/Week 76 of parent study.

Exclusion Criteria:

Ocular Exclusion Criteria:

• Active uveitis and/or vitritis (grade trace or above) in either eye

• Active, infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye

• Active or history of choroidal neovascularization (CNV) in study eye that requires anti-vascular endothelial growth factor (anti-VEGF) treatment

• Active or recent history (i.e., since enrollment in parent study) of optic neuritis in either eye

• Retinal pigment epithelium (RPE) tear that involves the macula in either eye

• Moderate or severe non-proliferative diabetic retinopathy in either eye

• Proliferative diabetic retinopathy in either eye

• Central serous retinopathy in either eye

• Recent history of recurrent infectious or inflammatory ocular disease in either eye

• Recent history of idiopathic or autoimmune-associated uveitis in either eye

• Any concurrent ocular or intraocular condition in the study eye that contraindicates the use of an investigational drug or may affect interpretation of the study results or may render the participant at high risk for treatment complications.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Ocular Adverse Events	An AE was defined as any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether considered related to the medicinal product, any new disease or exacerbation of an existing disease, recurrence of an intermittent medical condition, or any deterioration in a laboratory value or other clinical test. Ocular AEs are the events which are localized in the ocular region.	From baseline up to Week 104
Primary	Percentage of Participants With Systemic (Non-Ocular) Adverse Events	An AE was defined as any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether considered related to the medicinal product, any new disease or exacerbation of an existing disease, recurrence of an intermittent medical condition, or any deterioration in a laboratory value or other clinical test.	From Baseline up to Week 104
