Active clinical trials for "Neovascularization, Pathologic"

To demonstrate the efficacy of ranibizumab in combination with reduced-fluence verteporfin photodynamic therapy (RF-PDT) in patients with subfoveal choroidal neovascularization secondary to pathologic myopia (PM).

The purpose of the study is assess safety, bioactivity, and maximal tolerated dose of repeated weekly intravenous infusion of combretastatin A-4 phosphate (CA4P) in patients with neovascular age-related macular degeneration

Stretching effects skeletal muscle flexibility, vascularity and physical performance. The aim of our study is to examine the acute effects of static stretching duration on gastrocnemius muscle vascularization in healthy participants by superb microvascular imaging (SMI) and to compare the effects of 2 and 5 minutes of static stretching on blood flow.

This study will evaluate the effect of ranibizumab on patients undergoing vitrectomy surgery for the complications of diabetic retinopathy. Vitrectomy surgery can be difficult and bleeding after the operation can reduce vision for patients. Our hypothesis is that injection into the eye of ranibizumab one week before surgery will make the surgery easier, reduce complications and improve outcome. In this trial, patients will be randomly allocated to receive either ranibizumab injection or a placebo injection of saline. Neither the patient, their surgeon, nor the study investigators will know which they have received so that a fair comparison can be made.

The objectives of this study are to evaluate the safety and efficacy of 3 dose groups (27, 36 and 45 mg/m2) of Combretastatin A-4 Phosphate for the treatment of subfoveal choroidal neovascularization in subjects with pathologic myopia.

The purpose of the study was to compare 2 treatment regimens for patients suffering from choroidal neovascularisation secondary to age-related macular degeneration (AMD). The first treatment regimen was the approved AMD treatment of 1 injection each month for 3 months and than re-treatment of patients who have a visual loss of more than 5 letters with monthly control (Treat and Observe). The second treatment regimen was 1 injection each month for 3 months and than extending the control period if the macula is dry during the monthly control (Treat and Extend). If the "Treat and Extend" regimen is found effective and safe, the number of ranibizumab injections, the number of patient visits, the risk of adverse events due to the intravitreal injections, and policlinic occupation number could all be reduced.

The aim of the study is to evaluate whether PF-04523655 is safe in the treatment of neovascular/wet AMD

This study will examine whether the drug ranibizumab (Lucentis) can help prevent vision loss in people with macular telangiectasia, a condition in which new blood vessels grow in the retina at the back of the eye and can leak. Such changes in blood vessels are seen in other diseases associated with changes in a body chemical called vascular endothelial growth factor (VEGF). Ranibizumab is an anti-VEGF drug that is effective in treating another eye disease, age-related macular degeneration, with similar changes in eye blood vessels. People 18 years of age and older with macular telangiectasia in both eyes and new blood vessel growth in at least one eye may be eligible for this study. They must have vision better than 20/400 in the study eye. Participants undergo the following procedures: Ranibizumab injections in the study eye at least four times over 12 weeks. Depending on the response to treatment and the side effects, additional injections may be given every 4 weeks for up to 1 year. The eye is numbed before the injection and the eye area is cleaned with an antiseptic. Antibiotic drops are used for 3 days following the injection to prevent infection. Evaluations before starting treatment, at the time of each injection, and 8 weeks after the last treatment: History and physical examination. Eye examination with dilation, microperimetry and photography: The eye examination measures visual acuity, eye pressure and eye movements. For the microperimetry test, subjects sit in front of a computer screen and press a button when they see a light on the screen. Measurements and photographs of the retina are also taken. Fluorescein and indocyanine green angiography to examine the blood vessels in the eye: A dye called fluorescein or indocyanine green is injected into a vein in the arm. The dye travels through the veins to the blood vessels in the eyes. A camera takes pictures of the dye as it flows through the blood vessels. Pregnancy test: Women who are able to become pregnant have a urine pregnancy test before each ranibizumab injection.

Open-label Multicenter, Phase I/II Study comprising three phases (single dose, multiple dose and extension phase), Assessing the Safety and Efficacy of Ranibizumab (RFB002) in Japanese Patients With Subfoveal Choroidal Neovascularization (CNV) Secondary to Age-related Macular Degeneration (AMD).

A compassionate method of treatment is offered to patients where lesions do not meet acceptable criteria for standard therapy. Visudyne (Photodynamic Therapy) and laser photocoagulation treatment (a treatment using heat from a fine point laser beam) have not been found to be effective in treating the lesions these patients have. Anecortave acetate is an experimental drug that is being tested to prevent the growth of blood vessels under the retina in patients with age-related macular degeneration (AMD).
