September 29, 2014 updated by: Novartis Pharmaceuticals

Ranibizumab Treatment of Diabetic Macular Oedema With Bimonthly Monitoring After a Phase of Initial Treatment. A UK, 18-month, Prospective, Open-label, Multicentre, Single-arm, Phase IIIb Study With 12-month Primary Endpoint, Assessing the Efficacy and Safety of Ranibizumab in Patients With Visual Impairment Due to Diabetic Macular Oedema.

This study evaluates a new investigational treatment regimen of three consecutive monthly doses of ranibizumab followed by an as-needed treatment regimen, with monthly follow-up for the first three months then two-monthly follow-up until 18 months in patients with visual impairment due to diabetic macular oedema.The aim of the study is to determine if this treatment regimen is effective and safe in these patients.

Study Overview

Status

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients with Type 1 or Type 2 diabetes mellitus.
  • Patients with visual impairment due to focal or diffuse diabetic macular oedema (DMO), and not other causes, in at least one eye who are eligible for laser treatment in the opinion of the investigator.
  • Best Corrected Visual Acuity between 78 and 24 letters in the study eye using Early Treatment Diabetic Retinopathy Study (ETDRS)-like grading charts (approximate Snellen equivalent of 20/32 to 20/320).
  • Increased central retinal thickness which, in the opinion of the investigator, is due to DMO.

Exclusion Criteria:

  • Concomitant conditions in the study eye that could prevent the improvement of visual acuity on study treatment.
  • Active intraocular inflammation (grade trace or above) or infection in either eye at enrollment.
  • History of uveitis in either eye at any time.
  • Structural damage within 0.5 disc diameters of the centre of the macular in the study eye likely to preclude improvement in visual acuity following resolution of macular oedema.
  • Planned medical or surgical intervention during the 18-month study period.
  • Uncontrolled glaucoma in either eye at screening.
  • Blood pressure systolic > 160 mmHg or diastolic > 100 mmHg at screening.
  • Ocular conditions in the study eye that require chronic concomitant therapy with topical ocular or systemically administered corticosteroids.
  • History of acute thromboembolic event within 4 months of screening.
  • Untreated diabetes mellitus.
  • Evidence of advanced, severe or unstable concomitant disease or its treatment which may interfere with evaluations or put the patient at special risk.

Other protocol-defined inclusion/exclusion criteria may apply

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
The change in mean Best Corrected Visual Acuity (BCVA)
Time Frame: Baseline to 12 months
Baseline to 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame: Baseline to 18 months
Baseline to 18 months
Occurrence of ocular and systemic adverse events

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
