Brief Summary:

Neovascular age-related macular degeneration is characterized by the presence of choroidal neovascularization (CNV), which consists of abnormal blood vessels originating from the choroid that can lead to hemorrhage, fluid exudation, and fibrosis, resulting in photoreceptor damage and vision loss.

The safety and efficacy of brolucizumab were assessed in 2 randomized, multicenter, double-masked, active treatment-controlled Phase 3 studies in nAMD patients (the HAWK study (RTH258-C001 [NCT02307682]) and the HARRIER study (RTH258-C002 [NCT02434328]). Accordingly, a new Phase 3b study (TALON, CRTH258A2303) is being conducted to evaluate the efficacy and safety of brolucizumab in a Treat-to-Control (TtC) regimen for the treatment of naïve patients with nAMD. In this TtC regimen, patients receive 3 consecutive injections every 4 weeks and then the injection interval is extended by 4 weeks up to a maximum of a 16-week interval. The decision to extend or reduce the injection interval is taken by the Investigator at each visit based on his/her judgment of disease activity, according to the patient visual and/or anatomic outcomes. If there is no disease activity, the injection interval can be extended by 4 weeks ; if disease activity occurs or recurs, the injection interval should be shortened accordingly by 4 weeks at a time or to a minimal interval of 4 weeks. The injection interval can also be maintained if the Investigator deems that the patient do not benefit from injection interval adjustment.

Since all these studies were conducted in a naïve nAMD patient population, no data are available on the efficacy and safety of brolucizumab in pretreated nAMD patients who still present active exudation.

Arm Intervention/treatment
Experimental: RTH258/Brolucizumab
This is a single arm study in which all patients will be treated with blolucizumab 6mg; 3 loading injections (at Screening/Baseline, week 4 and week 8) followed by treat-to-control phase with adjustable treatment frequency based on disease activity from every 4 to up to 16 weeks; last treatment at week 44/46 based on the treatment regimen.
Drug: RTH258/Brolucizumab
Brolucizumab is a new generation of anti-VEGF (vascular endothelial growth factor). All patients will be treated with brolucizumab 6mg: 3 loading injections (at Screening/Baseline, Week 4 and Week 8), followed by Treat-to-Control regimen up to Week 44/46.

Inclusion Criteria:

  1. Patients must provide written informed consent before any study-related procedures are performed.

    Study eye:

  3. Active CNV lesions secondary to nAMD diagnosed < 18 months prior to Screening/Baseline that affect the central subfield, including retinal angiomatous proliferation (RAP) with a CNV component, confirmed by presence of active leakage from CNV seen by FA and sequelae of CNV, e.g. pigment epithelial detachment (PED), subretinal hemorrhage or sub RPE hemorrhage, blocked fluorescence, or macular edema.
  4. Previous treatment with only one licensed anti-VEGF drug (i.e. Lucentis®, Eylea®) with a ≥ Q4 and ≤ Q8 treatment (treatment interval of 26 to 62 days inclusive) with licensed anti-VEGF (a minimal washout period of at least 4 weeks / 26 days is required). Patients must have received at least 3 injections of this anti-VEGF in the 6 months prior to Screening/Baseline.

  27. Women of childbearing potential, defined as all women less than 1 year postmenopausal or less than 6 weeks since sterilization.

    Women are considered post-menopausal and not of childbearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy, or tubal ligation at least 6 weeks before taking study treatment. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of childbearing potential.
