Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Potential participants are eligible to be included in the study only if all of the following criteria apply:

* Signed ICF
* Age ≥ 50 years at the time of signing the ICF
* Caucasian
* Participants who are able to comply with the study protocol, in the investigator's judgment
* For female participants of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception as defined below:

Female participants must remain abstinent or use contraceptive methods with a failure rate of \< 1% per year, during the treatment period and for at least 3 months after the final dose of faricimab.

A female participant is considered to be of childbearing potential if she is post-menarche, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and is not permanently infertile due to surgery (i.e., removal of ovaries, fallopian tubes, and/or uterus) or another cause as determined by the investigator (e.g., Müllerian agenesis). Per this definition, a female participant with a tubal ligation is considered to be of childbearing potential. The definition of childbearing potential may be adapted for alignment with local guidelines or regulations.

Examples of contraceptive methods with a failure rate of \< 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.

The reliability of sexual abstinence should be evaluated concerning the duration of the clinical trial and the preferred and usual lifestyle of the individual.

Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not adequate methods of contraception.

If required per local guidelines or regulations, locally recognized adequate methods of contraception and information about the reliability of abstinence will be described in the local ICF.


* Sufficiently clear ocular media and adequate pupillary dilatation to allow acquisition of good quality retinal images to confirm diagnosis
* Confirmed diagnosis, by the Reading Centre, of naïve symptomatic macular PCV defined by the following:

* Active macular polypoidal lesions shown by ICGA AND
* Presence of exudative or haemorrhagic features involving the macula as identified by the investigator using multimodal images.
* BCVA scores of 78-24 ETDRS letters, inclusive (20/32 to 20/320 approximate Snellen equivalent), using the ETDRS protocol and assessed at the initial testing distance of 4 meters \[see the BCVA Standard Operational Procedures (SOP) for additional details\] on study Day 1.

* Continuous use of any medications and treatments indicated below:

* Systemic anti-VEGF therapy
* Systemic drugs known to cause macular oedema (fingolimod, tamoxifen)
* Other experimental therapies (except those comprising vitamins and minerals) and therapies that claim to have an effect on macular pathology (e.g., kallidinogenase)

* History of stroke (cerebral vascular accident) or myocardial infarction within 6 months prior to study Day 1
* History of other diseases, metabolic dysfunction, physical examination finding, or historical or current clinical laboratory findings giving reasonable suspicion of a condition that contraindicates the use of the IMP or that might affect the interpretation of the results of the study or renders the participant at high risk for treatment complications in the opinion of the investigator
* History of severe allergic reaction or anaphylactic reaction to a biologic agent or known hypersensitivity to any component of the faricimab injection, study-related procedure preparations (including fluorescein and indocyanine green dyes), dilating drops, or any of the anaesthetic and antimicrobial preparations used by a participant during the study
