Active clinical trials for "Edema"

This study will evaluate the safety and efficacy of an intravitreal insert of fluocinolone acetonide for the treatment of diabetic macular edema.

This study is being done to see if the investigational drug Ranibizumab (RBZ) given by injection into the eye, is safe and effective to use in people with diabetic macular edema (DME). The investigators want to compare RBZ to laser treatment which is the current standard way to treat DME. RBZ blocks a growth factor that is thought to be involved in the formation of abnormal blood vessels that cause loss of vision in patients with DME.

The purpose of this study is to evaluate the pharmacokinetics, safety and preliminary efficacy of 3 doses of Cand5. Cand5 is a small interfering RNA molecule that selectively silences the mRNA encoding for VEGF. The target population are patients with diabetic macular edema.

This study is a Phase III, double-masked, multicenter, randomized, sham injection-controlled study of the efficacy and safety of ranibizumab injection in patients with clinically significant macular edema with center involvement (CSME-CI) secondary to diabetes mellitus (Type 1 or 2). This study is identical in design to study NCT00473382 (Protocol ID FVF4168g). The open-label extension phase of the study was stopped after receiving FDA approval of the study drug (ranibizumab) for diabetic macular edema.

This study will evaluate the safety and efficacy of intravitreal implant of dexamethasone for the treatment of diabetic edema.

To evaluate the efficacy and safety of 7-day repeated oral administration of OPC-41061 15 mg or placebo in congestive heart failure (CHF) patients with extracellular volume expansion despite the use of a conventional diuretic.

To assess the ocular and systemic safety and tolerability of a single intravitreal injection of VEGF Trap in patients with diabetic macular edema.

This study will compare the safety and effectiveness of two treatments-injections of triamcinolone acetonide into the eye vs. standard laser therapy-for macular edema (swelling in the center of the retina) that is caused by blockage in a retinal blood vessel. Edema caused by blockage in a large vessel is called central retinal vein occlusion (CRVO). Edema caused by blockage in a smaller vein is called branch retinal vein occlusion (BRVO). Triamcinolone acetonide is a steroid drug that reduces swelling; the Food and Drug Administration has approved it for injection into joints and muscles to treat inflammatory conditions. Patients 18 years of age and older with macular edema due to CRVO or BRVO of between 3 and 18 months' duration may be eligible for this study. Candidates are screened with a medical history, blood pressure measurement, and urine pregnancy test for women who can become pregnant. Screening also includes the following procedures: Eye examination to assess visual acuity and eye pressure, and to examine the cornea, lens, and retina. The pupils are dilated with drops for this examination. Fluorescein angiography to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible blood vessel abnormality. Optical coherence tomography to measure retinal thickness. The eye is examined with a machine that produces cross-sectional pictures of the retina. The patient is seated in front of a machine and looks at a pattern of flashing and rotating red and green lights, first with one eye and then with the other. Fundus photography to help evaluate the status of the retina and changes that may occur in the future. Photographs of the retina are taken using a camera that flashes a bright light into the eye. Participants are randomly assigned to receive triamcinolone injections or standard treatment. Triamcinolone is given in either a 1-mg or 4-mg dose. Standard treatment for CRVO and for BRVO with excessive blood in the retina is observation. Standard treatment for BRVO without excessive blood is laser therapy. Patients with BRVO who do not qualify for laser therapy when they enter the study may have it later if blood clears enough to permit treatment. The procedures for triamcinolone injections and laser therapy are as follows: Triamcinolone acetonide: The eye is numbed with anesthetic drops and the study drug is injected into the vitreous, the jelly-like substance located between the back of the lens and the retina. Patients apply antibiotic drops at home for 3 days following the procedure. Laser treatment: The eye is numbed with anesthetic drops and a special contact lens is placed on the eye during the laser beam application. All patients are followed every 4 months for 3 years. Additional visits may be scheduled if needed. Patients who receive triamcinolone injections are also examined within 1 week of each injection and 1 month after each injection. At the 4-month visits patients undergo repeat eye examination and fundus photography. Optical coherence tomography is done at some visits, and fluorescein angiography is repeated at months 4, 12 and 24. Blood pressure is measured at months 12, 24 and 36. Patients may be retreated with triamcinolone injections or laser therapy as often as every 4 months, depending on their response to treatment.

This study will evaluate the safety and efficacy of an intravitreal implant of dexamethasone for the treatment of macular edema associated with retinal vein occlusion.

The trial will test the hypothesis that an intravitreal injection of triamcinolone is safe and efficacious for patients with clinically significant diabetic macular oedema that is recalcitrant to conventional laser therapy
