Study Description

Brief Summary:

This study looks to continue the study of anti-vegf therapy in patients with macular edema, and compare it to an anti-inflammatory therapy and a combined Anti-vegf and anti-inflammatory.

Condition or disease	Intervention/treatment	Phase
Diabetic Macular Edema	Drug: Efalizumab; Drug: Ranibizumab	Phase 1

Detailed Description:

Cell adhesion molecules are key mediators of inflammatory processes, which have been shown to play a role in the pathogenesis of diabetic retinopathy . Efalizumab inhibits the binding of leukocyte function-associated antigen-1 (LFA-1) to intercellular adhesion molecule-1 (ICAM-1) thereby inhibiting the adhesion of leukocytes to other cell types.

Clinical studies have demonstrated the bioactivities of intravitreal ranibizumab, a Vascular endothelial growth factor (VEGF) antagonist, in reducing retinal thickness and improving visual acuity in patients with diabetic macular edema (DME).

The objective of the CAPTURE Study is to assess the safety and tolerability of efalizumab, administered subcutaneously as a weekly (1 mg/kg) dose, compared to and in combination with ranibizumab, administered intravitreally (0.5 mg), in the treatment of DME.

Outcome Measures

Primary Outcome Measures :

1. To assess the safety and tolerability of efalizumab, compared to and in combination with ranibizumab, measuring the frequency and severity of adverse events. [ Time Frame: 6 mos ]

Secondary Outcome Measures :

1. To measure the mean change from Baseline to Month 6 and Month 12 in Best correct visual acuity (BCVA) [ Time Frame: 6 and 12 mos. ]
2. To evaluate the anatomic retinal changes as assessed by color fundus photography, fluorescein angiography, and Optical Coherence Tomography (OCT) [ Time Frame: 6 mos and 12 mos ]
