A Phase 2, Randomized, Placebo Controlled, Multicenter, Masked Study to Evaluate the Efficacy, Safety, Tolerability, and Pharmacodynamics of Multidose APL 3007 in Combination With Syfovre/Pegcetacoplan (APL-2) in Patients Diagnosed With Geographic Atrophy Secondary to Age Related Macular Degeneration

Phase 2 Interventional Apellis Pharmaceuticals, Inc. · NCT07215390

This trial will test whether adding APL-3007 to ongoing Syfovre (pegcetacoplan) injections can slow geographic atrophy progression in people aged 60 and older already receiving Syfovre.

What this trial studies

This is a Phase 2, randomized, placebo-controlled, masked multicenter trial enrolling patients with geographic atrophy (GA) secondary to age-related macular degeneration who have been on Syfovre (pegcetacoplan) for 6–24 months. Participants are randomized to receive multidose APL-3007 plus pegcetacoplan or placebo plus pegcetacoplan, with regular clinic visits for injections, retinal imaging, and visual acuity testing. The trial will track efficacy (lesion growth and vision measures), safety, tolerability, and pharmacodynamic biomarkers over the treatment period. Central reading center confirmation of GA and standardized ETDRS visual acuity are used to ensure consistent outcome measurement.

Who should consider this trial

Good fit: Ideal candidates are people aged 60 or older with GA from AMD, with NL-BCVA of 50 ETDRS letters or better, adequate ocular media and imaging, and prior Syfovre treatment every 6–8 weeks for at least 6 months but no more than 24 months.

Not a fit: Patients with very advanced vision loss, other significant eye diseases, or those who have not been receiving Syfovre as specified are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the combination could further slow GA lesion growth and help preserve vision beyond pegcetacoplan alone.

How similar studies have performed: Pegcetacoplan (Syfovre) alone has shown reduced GA lesion growth in prior Phase 3 trials, but combining it with APL-3007 is a novel approach with limited prior data.

Eligibility criteria

Show full inclusion / exclusion criteria 
Inclusion Criteria:

* The study eye must meet all inclusion criteria. If both eyes meet the inclusion criteria, the eye with better normal luminance visual acuity at the screening visit will be designated as the study eye. If both eyes have the same visual acuity, the right eye will be used as the study eye.
* Aged ≥60 years
* Clinical diagnosis of GA of the macula secondary to AMD in one or both eyes, as determined by the investigator and confirmed by the reading center
* NL-BCVA of 50 letters or better using early treatment diabetic retinopathy study (ETDRS) charts (approximately 20/100 Snellen equivalent)
* Adequate clarity of ocular media, adequate pupillary dilation, and fixation to permit the collection of good quality images in the study eye as determined by the investigator
* Prior treatment for GA in the study eye using Syfovre at 6-8 weeks interval for at least 6 months but no more than 24 months. Participants will be included if the participant has had at least 2 Syfovre injections in the last 6 months before screening.
* The GA lesion in at least 1 eye (designated as the study eye) must meet the following criteria as determined by the central reading center's OCT based RPE assessment of imaging at screening:

  * Total GA area must be ≥2.5 and ≤17.5 mm2 (1-7 disk areas \[DA\])
  * If GA is multifocal, at least 1 focal lesion must be ≥1.25 mm2 (0.5 DA), with the overall aggregate area of GA as specified above in 7a
  * The entire GA lesion must be completely visualized in the field of view of the OCT, with the GA RPE lesion border \>500 µm from the edge of the imaging window or any areas of peripapillary atrophy.
  * Nonsubfoveal lesion with border of GA lesion not encroaching center of the fovea. Distance of GA RPE lesion from center of the fovea \>0 based on OCT imaging.
  * Presence of any pattern of hyperautofluorescence based on FAF imaging in the junctional zone of GA. Absence of hyperautofluorescence (ie, pattern = none) is exclusionary.
* Documented evidence of vaccination within 5 years prior to screening, or willing to initiate vaccinations at least 14 days prior to dosing against:

  * Streptococcus pneumoniae (with a pneumococcal conjugate vaccine 15 \[PCV15\] or 20 \[PCV20\] or with pneumococcal polysaccharide vaccine 23 \[PPSV23\]),
  * Haemophilus influenzae (type B) (with Hib vaccine),
  * Neisseria meningitidis types A, C, W, and Y (with a quadrivalent meningococcal conjugate vaccine \[eg, Menactra or MenQuadfi\]), and
  * Neisseria meningitidis type B (with a meningococcal serogroup B vaccine \[eg, Bexsero\])

Female participants must be:

* Women of non-childbearing potential (WONCBP), or
* Women of childbearing potential (WOCBP) with a negative serum pregnancy test at screening and must agree to use protocol defined methods of contraception for the duration of the study and refrain from breastfeeding for the duration of the study (see Section 10.9.5.1)
