Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • • Signed informed consent and authorization of use and disclosure of protected health information
  • Age ≥18 years
  • Diagnosis of diabetes mellitus (type 1 or type 2)
  • Serum HbA1c ≥ 5.5% and ≤10% within 12 months of randomization. (It is important to be certain that the patients in the READ-4 Study have diabetes, which will suggest that the macular edema is secondary to diabetes. The American Diabetes Association has suggested that a HbA1c ≥ 5.5% may suggest the presence of diabetes mellitus.)
  • Have diabetic macular edema (DME) with central subfield thickness of ≥ 310 microns on spectral domain optical coherence tomography (SD-OCT).
  • Retinal thickening secondary to diabetes mellitus involving the center of the fovea (centered-involved macular edema).
Show all 11Show fewer
  • Best corrected visual acuity score in the study eye of 20/32 to 20/400 inclusive (Snellen equivalents using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol at a distance of 4 meters). If both eyes are eligible, the investigator will select the eye to be enrolled as the study eye. There is no specific visual acuity requirement for the fellow eye at time of study eye enrollment. However, if the fellow eye is to receive ranibizumab, it must have an entry visual acuity of 20/32 to 20/400 inclusive (Snellen equivalents using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol at a distance of 4 meters) at the time of the initial treatment.
  • In the opinion of the investigator, decreased vision in the study eye is due to foveal thickening from diabetic macular edema (DME) and not from other obvious causes of decreased vision.
  • Female of childbearing potential must have a negative serum pregnancy test within 28 days of randomization
  • Females of child-bearing potential may participate in this trial only if using a reliable means of contraception (e.g. physical barrier (patient and partner), contraceptive pill or patch, spermicide and barrier, or intrauterine device (IUD))
  • If a non-sterile male, commitment to the use of effective contraception (birth control) for the duration of the study is necessary.

About this study

Official title: Evaluation Of the Safety, Tolerability and Efficacy of Ranibizumab and Tocilizumab in Eyes With Diabetic Macular Edema.

The purpose of this study is to investigate the safety, tolerability and efficacy of Ranibizumab and Tocilizumab alone and in combination in eyes with Diabetic Macular Edema.

Read the detailed description

This study will evaluate the safety of intravenous (IV) infusions of Tocilizumab in the treatment of subjects with diabetic macular edema (DME) as monotherapy and in combination with intravitreal (IVT) Ranibizumab. It will also evaluate the percentage change in central retinal thickness (CRT) from baseline (BL) to Month 6 in the study eye as assessed by spectral-domain optical coherence tomography (SD-OCT). Other study objectives are to determine: the change in visual acuity (VA) from baseline to Months 3, 6 and 12, the change in CRT from baseline to Months 3, 6 and 12 in all the three treatment arms and determine the number of eyes requiring rescue therapy.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tocilizumab and Ranibizumab in people with Diabetic Macular Edema, run by University of Nebraska.

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 11 inclusion and 67 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: withdrawn, as of the sponsor's last update on 15 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Adverse Events (time frame: 6 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 NCT02511067, 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 15 Aug 2023.
