About this study

Official title: Comparative Study of the Efficacy of Intravitreal Ranibizumab Versus Its Combination With Commercial Dexamethasone in The Treatment of Diabetic Macular Edema

Intravitreal ranibizumab alone was Compared to adding dexamethasone to ranibizumab regarding central macular thickness, the visual acuity and the number of intravitreal injections needed to achieve the same effect on CMT and BCVA at the end of the 6 months duration of the study. Any significant change in final IOP, compared to baseline, in either group is reported.

Read the detailed description

This prospective randomized study measures the changes in central macular thickness, best corrected visual acuity and IOP in diabetic macular edema before and after the intravitreal injection of ranibizumab and dexamethasone, compared to ranibizumab alone, the current gold standard of care for diabetic macular edema.

Study participants were randomized into 2 groups: the first group received 3 Intravitreal injections of ranibizumab alone 1 month apart. While the second group received 1 Intravitreal injection of a combination of ranibizumab and 0.4 mg in 0.1 ml dexamethasone followed by 2 Intravitreal ranibizumab, 1 month apart (with dexamethasone if follow up OCT shows less than 10% improvement from baseline). Treatment was stopped when the treated eye achieved a central macular thickness of 250 microns or less with no focal parafoveal edema.

Final recorded central macular thickness in both groups compared to the baseline. By the end of the follow up period.

Final visual acuity was assessed in both groups compared to the baseline Change in final IOP, compared to baseline, in ranibizumab group and ranibizumab with dexamethasone group.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lucentis alone groupDrug

    The Lucentis alone group received 3 monthly intravitreal injections of lucentis alone or less than 3 injections if the central foveal thickness reached 250 microns

  • Lucentis dexamethasone groupDrug

    Lucentis dexamethasone group received intravitreal injections of combination of both lucentis and commercial dexamethasone. the second group received monthly intravitreal injections of the same dose of ranibizumab combined with 0.4 mg in 0.1 ml dexamethasone (Dexamethasone sodium phosphate, Amriya Pharmaceuticals, Cairo, Egypt) in a separate 1ml syringe with 27- gauge × ½ inch sterile injection needle, followed by 2 Intravitreal ranibizumab, 1 month apart (with dexamethasone if follow up OCT shows less than 10% improvement from baseline i.e., PRN). Treatment was stopped when CMT improved below 250 µ.

    Measured: 6 months after the first injection

  3. The number of injections

    The total number of injections in each Arm group

    Measured: over 6 months duration of the study

Secondary outcomes (1)
  1. IOP

    Intraocular pressure

    Measured: 6 months after the first injection

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lucentis alone group and Lucentis dexamethasone group in people with Diabetic Macular Edema, run by Cairo University at 1 site in Egypt.

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 2 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 9 Mar 2022. 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 Egypt. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 foveal thickness (time frame: 6 months after the first injection). The study lists 3 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 NCT05271539, which also lists 1 linked publication.

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 9 Mar 2022.
