About this study
Official title: Treatment of Recalcitrant Neovascular AMD Using Brolocizumab With a Novel Treat and Extend Protocol - a Randomized Controlled Prospective Study
The investigator propose to conduct a randomized clinical trial, investigating the safety and efficacy of brolucizumab for treatment of nAMD patients with CNV, and plans to specifically target those who are not responding to standard Treat and Extend (T\&E) treatment. A randomised omized study will be conducted with 2 arms, one with the new drug (brolocizumab) and novel treatment protocol versus a second arm using the current gold standard of aflibercept and the T\&E protocol
Read the detailed description
In addition, there will also be a rescue option for those in the aflibercept arm who are not responding well to also switch to brolucizumab. The primary outcome is the change in central macular thickness, since we expect the new treatment to be effective in reducing intraretinal and subretinal fluids, which in effect are indicators of disease activity. In addition, investigator will look at the improvement of visual acuity, the reduction of treatment intervals, total number of injections over 1 year, recurrence rate and safety profiles of both drugs.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Brolucizumab and Aflibercept in people with Age-Related Macular Degeneration, run by The University of Hong Kong at 1 site in Hong Kong.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Central Macular thickness (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05710471, which also lists 17 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2024.
