Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male or Female
  • Age ≥ 50 years
  • The presence of an active choroidal neovascular lesion secondary to AMD
  • On treatment with anti-VEGF therapy (Lucentis®, Eylea® or Avastin®)
  • Must have received at least 3 anti-VEGF treatments over the 26-week period prior to screening (Screening Visit)
  • Evidence that the macular fluid has responded to anti-VEGF in the past based on OCT in the opinion of PI
  • At screening, evidence of subretinal fluid and retinal cystic changes
  • Must have received anti-VEGF treatment within 10 days prior to pegcetacoplan treatment (anti-VEGF can be administered on the same day of the screening visit after the screening procedures have been completed)
  • OCTs of sufficient quality to allow for the assessment of the central macular fluid can be obtained
  • Female subjects must be:
  • Women of non-child-bearing potential (WONCBP), Or
  • Women of child-bearing potential (WOCBP) with a negative pregnancy test at screening and must agree to use protocol defined methods of contraception for the duration of the study
  • Males with female partners of child-bearing potential must agree to use protocol defined methods of contraception and agree to refrain from donating sperm for the duration of the study
  • Willing and able to give informed consent

Exclusion criteria

  • Choroidal neovascularization associated with other ocular diseases such as pathologic myopia, ocular histoplasmosis or posterior uveitis, etc
  • Decreased vision due to retinal disease not attributable to choroidal neovascularization, such as nonexudative forms of AMD, geographic atrophy, inherited retinal dystrophy, uveitis or epiretinal membrane, a vitelliform-like lesion of the outer retina (e.g., as in pattern dystrophies or basal laminar drusen), idiopathic parafoveal telangiectasis, or central serous retinopathy
  • Additional ocular diseases that have irreversibly compromised or, during follow-up, could likely compromise the VA of the study eye including amblyopia, anterior ischemic optic neuropathy, clinically significant diabetic macular edema, severe non proliferative diabetic retinopathy, or proliferative diabetic retinopathy
  • Decreased vision due to significant media opacity such as corneal disease or cataract, or opacity precluding photography of the retina
  • Cataract surgery within three months of enrollment
  • Presence of any hemorrhage
  • History of treatment for CNV:
  • Previous PDT treatment within 30 days prior to enrollment in the study
  • Previous extrafoveal or juxtafoveal thermal laser photocoagulation within 30 days prior to enrollment in the study
  • Intraocular surgery (including lens replacement surgery) within 3 months prior to randomization
  • Medical problems that make consistent follow-up over the treatment period unlikely (e.g. stroke, severe MI, end stage malignancy), or in general a poor medical risk because of other systemic diseases or active uncontrolled infections
  • Hypersensitivity to fluorescein

Treatment and study plan

Pegcetacoplan

Drug

On treatment day, subjects will be administered a single 100 μL IVT injection of pegcetacoplan at the dose corresponding to their treatment assignment.

Other names: APL-2

Primary outcomes

  1. Number of Subjects Who Experienced Ocular and Systemic Adverse Events (AEs), Including by Severity

    Time frame: Day 1 to Day 113

    Safety was assessed throughout the study. A TEAE was defined as any AE that started on/after the IVT injection of pegcetacoplan.

  2. Number of Dose Limiting Toxicities (DLTs)

    Time frame: Day 1 to Day 15

    The occurrence of any of the following AEs were considered DLTs: intraocular inflammation (vitritis or uveitis), endophthalmitis, sustained elevation of intraocular pressure ≥30 millimeters (mm) of mercury, and/or sustained loss of visual acuity ≥15 letters not attributable to the injection procedure or progression of disease.

  3. Median Area Under the Serum Concentration-Time Curve From Time Zero to Last Measurable Concentration (AUC[0-t])

    Time frame: Predose (screening), postdose Day 3 to Day 113

    The AUC(0-t) was measured using the linear trapezoidal method when concentrations were increasing and the logarithmic trapezoidal method when concentrations were decreasing. The median AUC(0-t) is presented for each cohort.

  4. Median Dose Normalized AUC(0-t)

    Time frame: Predose (screening), postdose Day 3 to Day 113

    The AUC(0-t) was measured using the linear trapezoidal method when concentrations were increasing and the logarithmic trapezoidal method when concentrations were decreasing. The dose normalized AUC(0-t) was calculated for each subject by dividing the parameter by the subject's respective dose in milligrams. The median dose normalized AUC(0-t) is presented for each cohort.

  5. Maximum Observed Serum Concentration (Cmax)

    Time frame: Predose (screening), postdose Day 3 to Day 113

    The median Cmax is presented for each cohort.

  6. Median Dose Normalized Cmax

    Time frame: Predose (screening), postdose Day 3 to Day 113

    The dose normalized Cmax was calculated for each subject by dividing the parameter by the subject's respective dose in milligrams. The median dose normalized Cmax is presented for each cohort.

  7. Median Time to the Maximum Measured Serum Concentration (Tmax)

    Time frame: Predose (screening), postdose Day 3 to Day 113

    The median Tmax is presented for each cohort. If the maximum value occurred at more than 1 time point, Tmax was defined as the first time point with this value.

Secondary outcomes

  1. Median Change From Baseline in Visual Acuity for the Study Eye

    Time frame: Day 1 to Day 113

    Best Corrected Visual Acuity (BCVA) letter score was determined using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters. The score ranges from 0 to 100 letters, lower number indicating reduced visual acuity; a positive value of change from baseline indicates visual acuity gain and a negative value indicates visual acuity loss.

  2. Median Change From Baseline in Central Retinal Thickness, Central Retinal Lesion Thickness and Central Subfield Thickness in the Study Eye

    Time frame: Day 1 to Day 113

    Central retinal thickness, central retinal lesion thickness and central subfield thickness were determined using Spectral Domain Optical Coherence Tomography (SD-OCT).

  3. Median Change From Baseline in Macular Cube Volume in the Study Eye

    Time frame: Day 1 to Day 113

    Macular cube volume was determined using SD-OCT.
