Study groups in NCT00901186
Study groupRoleWhat they receive
RFB002ExperimentalRFB002 0.5 mg was administered to the study eye with a single monthly intravitreal injection on day 1, day 30 and day 60. After day 90, if stable vision was not achieved, a monthly injection of RFB002 0.5 mg was administered until stable vision was achieved.
Receives: Drug: RFB002
Laser photocoagulationActive comparatorAt least one treatment of laser photocoagulation was applied on day 1. The maximum number of laser photocoagulation treatments was 4.
Receives: Procedure: Laser photocoagulation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Change From Baseline in Best Corrected Visual Acuity (BCVA)

    Visual acuity (VA) was assessed on the study eye during every study visit using best correction determined from protocol refraction. VA measurements were performed with the patient in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts at a testing distance of 4 meters.

    Measured: Baseline, 12 months

Secondary outcomes (5)
  1. Percentage of Participants With Improvement in BCVA

    Visual acuity (VA) was assessed on the study eye during every study visit using best correction determined from protocol refraction. VA measurements were performed with the patient in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts at a testing distance of 4 meters.

    Measured: 12 months

  2. Evolution of Mean Change From Baseline in BCVA by Study Visit

    Visual acuity (VA) was assessed on the study eye during every study visit using best correction determined from protocol refraction. VA measurements were performed with the patient in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts at a testing distance of 4 meters.

    Measured: Baseline, Months 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

  3. Percentage of Participants With VA > 73 Letters With Ranibizumab (0.5 mg) vs Laser.

    VA score was based on the number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart assessed at a starting distance of 4 meters.

    Measured: 12 months

  4. Mean Change From Baseline in Central Retinal Thickness (CRT) by Study Visit

    CRT was assessed by Optical Coherence Tomography (OCT).

    Measured: Baseline, Months 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

  5. Percentage of CRT Change From Baseline by Study Visit

    CRT was assessed by Optical Coherence Tomography (OCT).

    Measured: Baseline, Months 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RFB002 and Laser photocoagulation in people with Diabetic Macular Edema and Visual Impairment, run by Novartis Pharmaceuticals at 17 sites in Spain.

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 8 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 3 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 sites in Spain. 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 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?

Yes. Results are posted in the registry (first posted 3 Jul 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) (time frame: Baseline, 12 months). 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.

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 3 Mar 2017.
