AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Exclusion criteria
. There are choroidal neovascularization or other ocular diseases caused by BCD, which are considered to affect the operation or interfere with the interpretation of clinical endpoint.
. Patients with evidence of neovascularization or suspected neovascularization, and the presence of tubular reflectivity in the neuroepithelial layer as shown by OCT.
. Those who had used any of the treatment drugs within 6 months before enrollment, such as Lucentis, Avastin, Conbercept, Triamcinolone acetonide, etc. These may affect the experimental observation.
. The treated eyes have undergone intraocular surgery, such as photodynamic therapy (PDT), vitrectomy, periocular vascular bypass surgery, etc., or need intraocular surgery in the process of clinical research, such as cataract surgery, retinal laser therapy, etc.
. Have used or may use systemic drugs that may cause eye damage, such as psoralen, tamoxifen, etc.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Incidence of adverse events (AEs) from baseline to 52 weeks.
Timeframe: 52 weeks
2
Evaluate the improvement in BCVA compared to baseline at Week 12, 26 and 52.
. Highly sensitive or allergic to ingredients in the test drug (with allergic history of two or more drugs or food).
. Physical examination, vital signs, and laboratory examination (such as blood routine, urine routine, blood biochemistry, coagulation function, immunology examination, etc.) are abnormal and clinically significant, or the investigators believe that the abnormal indicators have clinical significance.
. There are diseases or medical histories that may affect drug safety or in vivo processes, especially cardiovascular, liver, kidney, endocrine, digestive tract, lung, nerve, blood, tumor, immune or metabolic disorders considered by investigators to be of clinical significance.
