Intervention model description: This study will be conducted in adult Caucasian participants with symptomatic macular PCV, a subtype of nAMD, which was under-represented in the faricimab Phase III pivotal Studies TENAYA (ClinicalTrials.gov identifier: NCT03823287) and LUCERNE (ClinicalTrials.gov identifier: NCT03823300) where less than 2% of the enrolled participants with nAMD were diagnosed with PCV and no Caucasian participants with symptomatic macular PCV were identified in the mentioned pivotal Studies.
Primary purpose: TREATMENT

Brief summary: The goal of this clinical trial is to assess the efficacy, safety and durability of faricimab in caucasian patients with polypoidal choroidal vasculopathy (PCV). The main question it aims to answer is:

To evaluate the efficacy of intravitreal (IVT) injections of faricimab 6 milligrams (mg) on Best Corrected Visual Acuity (BCVA) outcomes in caucasian patients with symptomatic macular PCV.

Participants will undergo ophthalmic examination, safety assessment and treatment with faricimab according to a patient specific treat and extend regimen.

Detailed description: Polypoidal choroidal vasculopathy (PCV) was first described in 1982 by Yannuzzi as a choroidal vasculopathy leading to haemorrhagic and exudative macular degeneration. More than four decades later, the pathogenesis of the disease remains uncertain with authors considering PCV a subtype of neovascular age-related macular degeneration (nAMD) while others advocate a separate clinical entity and adequate treatment is still an unmet need.

Several studies have reported an association between PCV and major and minor interethnic classification differences regarding morphological alterations, prevalence, genetic associations, lesion location, and results after anti-vascular endothelial growth factor (VEGF) treatment, among others. For instance, the reported prevalence of PCV in patients with neovascular AMD ranges from 4% to 9,8% in Caucasians and from 22% to 55% in Asians. However, a recent study reported a much higher prevalence in Caucasians (22,1%), suggesting that PCV may actually be underdiagnosed in this population.

Today, intravitreal (IVT) anti-VEGF therapy plays a key role in the management of PCV and has become the standard of care. The anti-permeability property of anti-VEGF agents, such as aflibercept and ranibizumab, play a role in reducing the exudation from abnormal choroidal vessels and polypoidal lesions, thereby decreasing the subretinal fluid and preserving vision.

Although the current standard of care has demonstrated clinical benefit for patients with PCV, many limitations exist in understanding the disease as a result of its heterogeneity in clinical features and treatment outcomes. The burden of frequent injections, incomplete polypoidal lesion closure, and the risk and unpredictability of lesion relapse reinforce the need to develop new treatments for patients with PCV. This population is at risk of disease relapse, retinal haemorrhage, and vision loss, and is appropriate for inclusion in this clinical trial.

Faricimab is a novel humanized bispecific Immunoglobulin G1 (IgG1) monoclonal antibody that selectively binds with high affinity to VEGF-A and angiopoietin-2 (Ang-2). Faricimab was studied for the treatment of neovascular AMD (nAMD) in the global Phase III Studies TENAYA (ClinicalTrials.gov identifier: NCT03823287) and LUCERNE (ClinicalTrials.gov identifier: NCT03823300) and is currently being studied in the long-term extension Study AVONELLE-X (ClinicalTrials.gov identifier: NCT04777201). The TENAYA (ClinicalTrials.gov identifier: NCT03823287) and LUCERNE (ClinicalTrials.gov identifier: NCT03823300) studies consistently showed that faricimab, given at intervals of up to 16 weeks, offered non-inferior vision gains compared with aflibercept, given every 2 months in the first year. Approximately 50% of participants eligible for extended dosing with faricimab were able to be treated every 4 months, and nearly 80% of participants every 3 months or longer. However, patients with symptomatic macular PCV were under-represented in the faricimab Phase III pivotal Studies TENAYA (ClinicalTrials.gov identifier: NCT03823287) and LUCERNE (ClinicalTrials.gov identifier: NCT03823300).

The purpose of this study is to assess the efficacy, durability, and safety of faricimab 6 mg IVT administered at up to 24-week intervals in the treatment-naive study eye of Caucasian patients with symptomatic macular PCV. This study will add to the evidence base for the benefit-risk profile of faricimab IVT injection in Caucasian patients with symptomatic macular PCV.

The study consists of a screening period of up to 28 days (Days -28 to -1) in length and an approximately 100-week study treatment period consisting of a Treatment Initiation period (Weeks 1-12) and the treat and extend (T\&E) regimen period (Weeks 20-Week 100).
