Filter by:This is s randomized, multi-center, double blind, 3 arm, phase I/II pilot study to evaluate the safety and efficacy of treatment with ORA102 combined with Avastin (Bevacizumab) versus Avastin alone, in patients with neo-vascular age related macular degeneration (AMD).
This phase II study was designed to evaluate the safety, tolerability, and efficacy of bevacizumab treatment in conjunction with PDT at the low fluence rate compared with bevacizumab alone or combined with PDT at the standard fluence rate, in patients with all types of choroidal neovascularization secondary to AMD. Hypothesis: bevacizumab in combination with PDT (low and standard fluence rate) will i) delay time to retreatment, ii) reduce the average number of treatments required compared to bevacizumab alone and iii) at low PDT fluence rate will improve long-term safety profile.
One concern about repeated intravitreal injections of bevacizumab (Avastin) and ranibizumab (Lucentis) in wet age related macular degeneration, is that in addition to blocking the proteins that triggers the development and proliferation of abnormal vessels in the center of the retina, they may also result in changes in the normal vessels that feeds the outer part of the retina. Small vessels with fenestrations (such as those that feed the outer part of the retina, which are called choriocapillaris) appear to be especially sensitive to this protein (called vascular endothelial growth factor, VEGF) withdrawal. It is estimated that global blood flow in the vascular layer under the retina (called choroid) may be indirectly assessed by measuring the amplitude of the ocular pulsation (the pressure inside the eye change according to the cardiac cycle, similar to the change in blood pressure) which is called Ocular Pulse Amplitude (OPA). The Pascal Dynamic Contour Tonometer (Pascal DCT) is a new tonometer (a device which measures the pressure within the eye) designed to measure intraocular pressure and ocular pulse amplitude. No published study has yet assessed the effect of bevacizumab (Avastin) or ranibizumab (Lucentis) treatment for wet AMD (or on any other retinal disease) on OPA. This is our aim in this pilot study, in which we will measure the pressure within the eye just prior to bevacizumab/Ranibizumab treatment, followed by repeated measurements a week and a month after the treatment. For this purpose, up to 60 patients with wet AMD will be recruited.
The study is designed to demonstrate the therapeutic non-inferiority of the recombinant humanized monoclonal VEGF antibody bevacizumab administered by intravitreal injection in the treatment of AMD in comparison to the related fragment ranibizumab.
To compare the efficacy and safety of photodynamic therapy (PDT) combined with intravitreal bevacizumab versus combination of photodynamic therapy , intravitreal bevacizumab and intravitreal triamcinolone for neovascular AMD.
The study will investigate the safety and feasibility of using the TheraSight(TM) Brachytherapy System for treatment of wet age-related macular degeneration (AMD).
