Efficacy and Safety of Ranibizumab in Two "Treat and Extend" Treatment Algorithms Versus Ranibizumab As Needed in Patients With Macular Edema and Visual Impairment Secondary to Diabetes Mellitus (RETAIN)
10 settembre 2014 aggiornato da: Novartis Pharmaceuticals
A 2 Year Randomized, Single-masked, Multicenter, Controlled Phase IIIb Trial Assessing the Efficacy and Safety of 0.5 mg Ranibizumab in Two "Treat and Extend" Treatment Algorithms vs. 0.5 mg Ranibizumab As Needed in Patients With Macular Edema and Visual Impairment Secondary to Diabetes Mellitus
The purpose of this study is to demonstrate that two investigational treatment regimens have the potential to result in a superior visual acuity improvement as compared to a ranibizumab pro re nata (PRN=as needed) treatment regimen.

Descrizione
Inclusion Criteria:
Patient
- Patients with Type 1 or Type 2 diabetes mellitus (according to American Diabetes Association or World Health Organization [WHO] guidelines) with glycosylated hemoglobin (HbA1c) ≤ 12.0% at screening (Visit 1). Patients should be on diet, exercise, and/or pharmacological treatment for diabetes. Treatment for diabetes must have been stable for at least 3 month.
Ocular
- Patients with visual impairment due to DME in at least one eye who are eligible for laser treatment in the opinion of the investigator. If both eyes are eligible, the one with the worse visual acuity, as assessed at Visit 1, will be selected by the investigator as the study eye.
- BCVA ≥ 39 and ≤78 letters in the study eye and, inclusively, using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts at a testing distance of 4 meters (approximate Snellen equivalent of 20/32 to 20/160) at screening.
- Concomitant conditions in the study eye are only permitted if, in the opinion of the investigator, they do not prevent improvement of visual acuity on study treatment.
Exclusion Criteria:
Patient Compliance/ Administrative
- Pregnant or nursing (lactating) women.
Ocular medical history
- Active intraocular inflammation (grade trace or above) in either eye at enrollment.
- Any active infection (e.g. conjunctivitis, keratitis, scleritis, uveitis, endophthalmitis) in either eye at the time of enrollment.
- History of uveitis in either eye at any time.
- Structural damage within 0.5 disc diameter of the center of the macular in the study eye likely to preclude improvement in visual acuity following the resolution of macular edema.
- Uncontrolled glaucoma in either eye at screening.
Prior Ocular treatments
- Panretinal laser photocoagulation in the study eye within 6 months prior to randomization.
- Focal/grid laser photocoagulation in the study eye within 3 months prior to randomization.
- Treatment with anti-angiogenic drugs in either eye.
Systemic conditions or treatments
- History of stroke within 6 months prior to enrollment.
- Renal failure requiring dialysis.
- Untreated diabetes mellitus.
- Blood pressure systolic > 160 mmHg or diastolic > 100 mmHg.
Other protocol-defined inclusion/exclusion criteria may apply

Sperimentale: TE Ranibizumab 0.5 mg and Laser
On Day 1, all patients received an intravitreal injection with 0.5 mg ranibizumab and subsequently entered Phase A which comprised of monthly injections.
Laser therapy was applied at Day 1.
It could then be re-administered according to ETDRS criteria at any visit with 0.5 mg ranibizumab treatment if deemed necessary by the Treating Investigator with a minimal treatment interval between laser treatments of 3 months.
Laser therapy was administered ≥ 30 minutes prior to the ranibizumab injection.

Ranibizumab (Lucentis®) was supplied in vials containing a dose of 0.5 mg/0.05
mL in an aqueous solution (pH 5.5) with histidine, trehalose, and polysorbate 20.

Sperimentale: TE Ranibizumab 0.5 mg alone
Patients received ranibizumab intravitreal injection therapy only.

Central Subfield Thickness of the Study Eye: Percent Change From Baseline at Month 12
Lasso di tempo: Baseline, Month 12

High Resolution OCT was performed at every study visit by Spectral Domain OCT (if not available Time Domain OCT was acceptable) and the images were transferred to a digital video disc.
These assessments were performed by trained and adequately qualified experts at the sites and prior to any study drug administration.
CSFT is the average retinal thickness of the circular area with 1 mm diameter around the foveal center.

The National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) was used to measure the influence of visual disability and symptoms on general health.
The 12 subscales in the VFQ-25 are general health, general vision, ocular pain, near activities, distance activities, social function, mental health, role difficulties, dependency, driving, color vision, and peripheral vision.
For each, the patient was asked to rate their condition on a scale of 1-5 or 1-6, where a low number reflects a better outcome.
Each response was recoded per the scoring rules outlined in the National Eye Institute (NEI) VFQ-25 Scoring Algorithm.
Under this scoring algorithm , the recoded values range between 0 and 100 and a high score means a better functioning

The Euro Quality of Life Questionnaire (EQ-5D) is an indirect utility questionnaire.
It is a standardized instrument was utilized to measure health outcomes related to 5 dimensions, namely: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.
The possible range for each dimension was 1 to 3, where 1= "no problems", 2="some problems" and 3="extreme problems" .
A composite health index was then defined by combining the levels for each dimension.
Overall, 243 health states are possible.
For each health state, the EuroQol group has assigned a utility value typically between 0 and 1 with lower scores representing a higher level of dysfunction
