Active clinical trials for "Neovascularization, Pathologic"

The purpose of this study is to evaluate the effects of panretinal photocoagulation plus intravitreal ranibizumab for the treatment of patients with high risk proliferative diabetic retinopathy in terms of changes in visual acuity and neovascularization area.

The purpose of this study is to determine the safety and efficacy of a drug [Pazopanib (Votrient)] as a treatment for corneal neovascularization. The cornea is the clear, central portion of the eye and neovascularization means blood vessel growth. The cornea is typically avascular, or without blood vessels. Corneal neovascularization in the cornea and can put vision at risk. Numerous diseases of the cornea such as inflammation, ischemia (restriction of blood supply), infection, degeneration (or deterioration), trauma, or corneal stem cell deficiency can lead to corneal neovascularization. This major ocular complication can lead to corneal scarring, edema (swelling), lipid deposits, and inflammation that may significantly alter your vision. In addition, it worsens the outcome of potential future treatments, such as a corneal transplant. A corneal transplant is a treatment that many patients with severe corneal disease may ultimately need.

The purpose of this study is to determine the effectiveness and safety of ranibizumab (Lucentis) in treatment of corneal neovascularization.

Eight patients with corneal neovascularization were treated with subconjunctival injection of 1.25 mg bevacizumab and had a follow-up of at least 2 months. All patients had persistent corneal neovascularization for at least 6 months unresponsive to other treatments. Patients were monitored by ophthalmic exam and anterior segment photography.

To report the short term anatomic and visual acuity response after intravitreal injection of bevacizumab (Avastin, Roche, Rio de Janeiro, Brazil) in patients with choroidal neovascularization secondary to age-related macular degeneration.

The study intends to assess the effect of Avastin injections in different proliferative retinopathies due to different causes

This study evaluated the effect of combination therapy with verteporfin photodynamic therapy and ranibizumab on visual acuity and anatomic outcomes compared to ranibizumab monotherapy and the durability of response observed in patients with choroidal neovascularization secondary to age-related macular degeneration.

The purpose of this first-in-human study is to evaluate the safety, pharmacokinetics (PK) and pharmacodynamics of OPT-302 administered as monthly intravitreal injections for 3 months with and without Lucentis™ in patients with wet age related macular degeneration (AMD). This study will be conducted in two parts: Part 1 will comprise an open label, sequential dose escalation and Part 2 a randomized dose expansion. OPT-302 is a soluble form of VEGFR-3 comprising the extracellular domains 1-3 of human vascular endothelial growth factor receptor (VEGFR)-3 and the Fc fragment of human IgG1. It functions by binding and neutralizing the activity of vascular endothelial growth factor (VEGF)-C and VEGF-D on endogenous VEGFR-2 and VEGFR-3. VEGF-C and VEGF-D promote blood vessel development (angiogenesis) by binding and activating VEGFR-2 and VEGFR-3. VEGF-C is also a potent inducer of vascular permeability or leakage. Angiogenesis and vascular leakage are key hallmarks of wet AMD. Approved therapies for wet AMD include Eylea™ and Lucentis™ which block the activity of VEGF-A, but not VEGF-C or VEGF-D which are alternate members of the same family of molecules. VEGF-C and VEGF-D can stimulate blood vessel growth and leakage through the same pathway as VEGF-A (via VEGFR-2), as well as through pathways that are independent of VEGF-A (via VEGFR-3). Published studies have also indicated that VEGF-C and VEGF-D play an important role in mediating resistance to therapies that block VEGF-A such as Lucentis™ and Eylea™. Combination therapy with OPT-302 an anti-VEGF-A agent provides a more complete blockade of the VEGF family. This strategy targets functional redundancy in the VEGF pathway and mechanisms of 'resistance' or sub-response to VEGF-A inhibition.

This is an interventional, prospective, randomized, comparative monocentric study aiming to evaluate the safety and efficacy of Resveratrol to reduce the progression of exudative Age-Related Macular Degeneration.

This study was conducted to evaluate the efficacy and safety of 0.5 mg ranibizumab in adult and adolescent patients with visual impairment due to choridal neovascularization (CNV).
