About this study
Official title: Dosing Strategy of Intravitreal Ranibizumab for Myopia Choroidal Neovascularization: a Single Center Randomized Prospective Study
The purpose of this study is to compare the efficacy (times of injection, change of visual acuity and Cva/ I) and safety (macular visual function and choroidal thickness) of different dosing of ranibizumab intravitreal injection (1+PRN vs. 3+PRN) in treating with pathological myopia choroidal neovascularization (PM-CNV).
Read the detailed description
PM is a common disease in east asia, while PM-CNV affect 5%-10% PM patients.PM-CNV has specific characteristics, including small dimensions and limited exudative manifestations comparing with age-related macular degeneration. However, treatment regimen and re-treatment criteria follow the PrONTO protocol. The question of the optimal dose and treatment regimen in myopic CNV management is still unresolved. There is no unequivocal evidence suggesting hat PRN treatment is more effective than a loading phase followed by an as-needed variable dosage regimen.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
0.5mg intravitreal ranibizumabDrug
Also called IVR 0.5mg
Patients received ranibizumab (0.5mg, Novartis AG, Basel, Switzerland) via a pars plana transcleral injection through 30-gauge needle at 3.5 to 4mm of inferotemporal limbus. Levofloxacin eye drops ( Cravit Eye Drops, Santen, Japan) was instilled 4 times a day in the study eye before the treatment at least 1 day. Povidone-iodine (5%, Luofushan Pharmaceutical Co., China) was applied to the conjunctiva bulbi and the fornices for at least 3 minutes before injection. Patients were instructed to continue the levofloxacin eye drops 4 times a day for 3 days
| Study group | Role | What they receive |
|---|---|---|
| Group A | Active comparator | Group A included 30 patients treated with one 0.5mg intravitreal ranibizumab injection. All patients were followed monthly for 12 months with additional injections performed as needed. Receives: Drug: 0.5mg intravitreal ranibizumab |
| Group B | Active comparator | Group B included 30 patients treated with three monthly 0.5mg intravitreal ranibizumab injections. All patients were followed monthly for 12 months with additional injections performed as needed. Receives: Drug: 0.5mg intravitreal ranibizumab |

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing 0.5mg intravitreal ranibizumab in people with Choroidal Neovascularization, run by Zhongshan Ophthalmic Center, Sun Yat-sen University at 1 site in China.
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 4 inclusion and 4 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 11 Mar 2019. 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 China. 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?
Injection Number (time frame: 12 months). The study lists 2 primary outcomes in all. 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 NCT03042871, which also lists 14 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 11 Mar 2019.
