A Phase I/II Trial for Intravitreous Treatment of Severe Ocular Von Hippel-Lindau Disease Using a Combination of the PDGF Antagonist E10030 and the VEGF Antagonist Ranibizumab
In Brief
A Phase 2 clinical trial evaluating Ranibizumab and E10030 for Von Hippel-Lindau Syndrome. Completed, enrolled 3 participants across 1 site.
Detailed Summary
Background: People with Von-Hippel-Lindau (VHL) disease may experience significant vision loss as a result of retinal capillary hemangiomas (RCH), the most common and often earliest manifestation of VHL. Objective: To investigate the safety and possible efficacy of combination investigational treatment with serial intravitreal injections of E10030, a PDGF-B antagonist, and ranibizumab, a VEGF-A antagonist, in participants with severe ocular VHL disease. Design: Three participants with severe ocular VHL disease will receive the combination investigational treatment in one eye and will be followed for 104 weeks. Primary Outcome: The safety of the combination investigational treatment, assessed by tabulation of adverse events reported through Week 52.

Interventions
Intravitreal injections of the commercially-available 10 mg/mL formulation of ranibizumab. Ranibizumab is formulated as a sterile solution (pH 5.5) with histidine, trehalose and polysorbate 20. The vial contains no preservative. Each vial contains 0.5 mL of 10 mg/mL ranibizumab aqueous solution. The intravitreal injection volume of ranibizumab is 50 microliter, which correlates to 0.5 mg of dry ranibizumab.
E10030 is not a commercially available drug product, and will be provided by Ophthotech Corp. The drug product is provided as a sterile aqueous solution of E10030 at a concentration of 30 mg (oligo weight)/mL. The solution contains monobasic sodium phosphate monohydrate and dibasic sodium phosphate heptahydrate as buffering agents as well as sodium chloride as a tonicity adjuster. The intravitreal injection volume of E10030 is 50 microliter, which correlates to 1.5 mg of dry E10030.
