|---|---|---|
| Conbercept intravitreal Injection | Experimental | Not described Receives: Drug: Conbercept ophthalmic injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
To evaluate the 1-year ocular salvage rate of intravenous chemotherapy combined with Conbercept intravitreal injection in the treatment of retinoblastoma
12-month ocular salvage rate: calculate the number and percentage of subjects who reach 12-month ocular salvage rate, and use the exact probability method to estimate 95% CI.
Measured: 1 year

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
To evaluate the 1-year ocular salvage rate of intravenous chemotherapy combined with Conbercept intravitreal injection in the treatment of retinoblastoma (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
