| New Formulation | NCT00071227 ↗ | Eye Injections of Triamcinolone Acetonide for Retinal Blood Vessel Disorders | Completed | National Eye Institute (NEI) | Phase 1 | 2003-10-15 | This study will evaluate the safety and effectiveness of a new formulation of triamcinolone acetonide for the treatment of retinal blood vessel disorders. Triamcinolone is a steroid drug that decreases inflammation and scarring and is routinely used to treat eye inflammation or swelling. The commercially available form of this drug is associated with potentially harmful side effects thought to be due to preservatives in the preparation. This study will use a formulation that does not contain these potentially harmful preservatives. Preliminary findings from other studies suggest that injection of steroids in the eye can reduce retinal thickening and improve vision. However, they may also cause mild discomfort and lead to vision-threatening conditions. The effects of the drug on the conditions under study in this protocol are not known. Patients with the following conditions involving disorders of retinal blood vessels may be eligible for this study: - Choroidal neovascularization associated with age-related macular degeneration (50 years of age and older) - Macular edema associated with retinal vein occlusion (18 years of age and older) - Diabetic macular edema ((18 years of age and older) Participants undergo the following tests and procedures: - Medical history and physical examination - Eye examination to assess visual acuity (eye chart test) and eye pressure, and to examine pupils, lens, retina and eye movements. The pupils will be 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. - Indocyanine green angiography to identify feeder vessels that may be supplying abnormal blood vessels. This procedure is similar to fluorescein angiography, but uses a green dye and flashes an invisible light. - Optical coherence tomography to measure retinal thickness. This test shines a light into the eye and produces cross-sectional pictures of the retina. These measurements are repeated during the study to determine if retinal thickening is getting better or worse, or staying the same. - Stereoscopic color fundus photography to examine the back of the eye. The pupils are dilated with eye drops to allow examination and photography of the back of the eye. - Triamcinolone acetonide injection to treat the eye. A numbing eye drop, an antibiotic eye drop, and an injected antibiotic are put in the eye before triamcinolone acetonide is injected into the eye's vitreous (jelly-like substance inside the eye). After the injection, the patient lies on his or her back for 30 minutes. An antibiotic eye ointment is used for 2 days following treatment. - Blood tests to measure liver and kidney function. Patients return to the clinic for follow-up visits 1, 4, and 7 days, and 1 month after the first treatment. Patients whose condition does not improve after 3 months do not receive any more injections, but return for eye examinations at least once a year for 3 years. Patients whose condition improves with treatment return for follow-up visits 6 and 9 months after the first injection and then every 6 months for 2 more years. At each visit, a determination is made whether another injection is needed. After each repeat injection, patients return for follow-up visits at 1, 4, and 7 days after the injection. |

To determine the bioavailability of synthetic hypericin given in 2 percent benzyl alcohol solution. Hypericin is unlike other drugs presently being used to treat AIDS patients. Hypericin shows anti-HIV activity in test tube experiments. |

| NCT00100009 ↗ | Triamcinolone Acetonide Plus Laser Therapy to Treat Age-Related Macular Degeneration | Completed | National Eye Institute (NEI) | Phase 3 | 2004-12-09 | This study will test the safety and effectiveness of combining a laser treatment called photodynamic therapy, or PDT, with injections into the eye of the steroid triamcinolone acetonide for treating age-related macular degeneration (AMD). The macula is the part of the retina in the back of the eye that determines central or best vision. AMD can severely impair central vision, affecting a person's ability to read, drive, and carry out daily activities. This vision loss is caused by the formation of abnormal blood vessels behind the retina that leak blood under the macula. PTD stops the growth of these blood vessels and slows the rate of vision loss; however, it has only a temporary effect and does not work in all patients. Furthermore, it may actually cause some swelling and re-growth of blood vessels. Triamcinolone acetonide can help lessen swelling and scarring. Patients 50 years of age and older with AMD may be eligible for this study. Candidates are screened with a medical history, medical evaluation, and eye examinations (see below). Participants are randomly assigned to one of three treatment groups: 1) PDT plus 1 mg TAC-PF; 2) PDT plus 4 mg TAC-PF; or 3) PDT plus sham injection (a syringe with no needle is pressed against the eye). Treatments are given the day the patient enrolls in the study and then every 3 months for 2 years, as long as the therapy is thought beneficial. Patients who must discontinue TAC-PF injections may still be treated with PDT if medically necessary. In addition to treatment, patients undergo the following tests and procedures: - Eye examination: Visual acuity and eye pressure are measured, and the lens, retina, pupils and eye movements are examined. - Fundus photography: Photographs of the back of the eye are taken using a special camera with a bright flash. - Lens photography: Photographs of the lens are taken to look for development of cataracts. - Fluorescein angiography: Pictures of the retina are taken to look for abnormal blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. The retina is photographed 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: This test uses light to produce a 2-dimensional cross-sectional picture of the retina. The patient looks into a machine called an optical coherence tomograph at a pattern of flashing and rotating red and green lights, first with one eye and then the other. - PDT: A needle is placed in an arm vein and a drug called verteporfin (Visudyne® (Registered Trademark)) is infused into the vein over 10 minutes. After 15 minutes, the eye is anesthetized with numbing drops. A special contact lens is then placed on the eye and the laser beam is directed to the eye for 83 seconds. - TAC-PF or injections (for those in the TAC-PF treatment groups): Numbing and anesthetic drops are placed on the surface of the eye before injection of TAC-PF. Another anesthetic is then applied to the lower part of the eye with a cotton swab. After a few minutes, TAC-PF is injected into the vitreous (jelly-like substance inside the eye). Patients receiving sham injections undergo the identical procedure, except a syringe with no needle is pressed against the eye to seem like a real injection. All patients receive antibiotic drops to put in their eye for 2 days after each treatment. Patients return to the clinic anytime from 2 to 7 days after each treatment for a check of vision, eye pressure, and treatment side effects. Patients are seen in the clinic for additional checks at 4 weeks and 4 months after the first treatment. |
