Filter by:The purpose of this study is to confirm the efficacy and safety of rostaporfin (PHOTREX) photodynamic therapy (PDT) in the treatment of classic and occult subfoveal choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD).
This study will examine the efficacy and safety of pegaptanib sodium in Japanese patients with wet-type AMD, in order to establish that there is no large difference in the efficacy and the safety of the drug between Western and Japanese patients.
A 24 - month Study looking at the the changes in visual acuity of patients receiving PDT therapy in conjunction with intravitreal triamcinolone.
To determine whether VISUDYNE therapy in combination with 4 mg intravitreal triamcinolone will reduce the average loss from baseline of best corrected visual acuity (BCVA) as compared with Visudyne therapy without intravitreal triamcinolone at 12 months in subjects with occult subfoveal and minimally classic subfoveal CNV secondary to AMD. The intravitreal triamcinolone will be given as either a 1 mg or 4 mg dose. This study will also evaluate the safety of Visudyne therapy in combination with intravitreal triamcinolone. An interim statistical readout will be performed when the first 60 patients have completed 6 months of follow-up evaluation.
Age-Related Macular Degeneration (AMD) is a degenerative eye disease of the retina that causes a progressive loss of central vision. AMD is the leading cause of blindness among adults age 50 or older in the Western world. AMD presents in two different types: "dry" and the more severe "wet" form. Wet AMD is caused by the growth of abnormal blood vessels in the macula. Squalamine lactate is an investigational drug that may prevent the growth of these abnormal blood vessels. This study will evaluate the safety and efficacy of Squalamine lactate in the treatment of AMD in patients, the exact number of which will be determined based on data from the sponsor's ongoing Phase 2 trials. The trial objective is to evaluate the safety and efficacy of two doses of Squalamine lactate for Injection administered as intravenous infusions weekly for 4 weeks followed by maintenance doses every 4 weeks through week 104 compared with the safety and efficacy in the control group.
This study evaluates the tolerability and safety of 3 months treatment with PTK787 tablets given daily. It also explores the efficacy of the compound in patients with wet age-related macular edema. In Cohort 1 verteporfin/PDT is the active control. The protocol was amended to reflect the current standard of care for AMD. As a result, ranibizumab is the active control for Cohort 2.
Age related macular degeneration is the leading cause of blindness for people over 50 in the western world. Blood vessels which start to grow form a lesion in the back of the eye. Verteporfin may stabilize the disease, by closing the blood vessels. This study will assess the efficacy and safety of verteporfin in patients with occult only lesions.
The purpose of the trial is to compare whether Macugen (pegaptanib sodium) in combination with PDT with Visudyne (verteporfin) is safe and effective in slowing down the leakage of fluid within the eye and thereby stabilizing or improving vision when compared to Macugen alone. Patients must be recently diagnosed with predominantly classic wet AMD and must be eligible for PDT.
This study will explore whether taking the vitamins lutein and zeaxanthin, with or without Omega-3 fatty acid (fish oil or docosahexanoic acid, also known as DHA) will change the amount of lutein and zeaxanthin in the blood among people with age-related macular degeneration (AMD). AMD is one of the leading causes of legal blindness among people over the age of 50 in developed countries. In the disease, the retina of the eye, the sensory portion, worsens in condition. AMD causes progressive loss of central vision, with only peripheral vision remaining, that is, the ability for someone to see from the edges of the eye. To date, there is not any effective treatment to improve vision for most people whose AMD is advanced. Yet some data from research studies suggest a possible role of antioxidants, including lutein, in reducing the risk of AMD and cataracts. Lutein and zeaxanthin belong to the carotenoid family of vitamins, of which there are more than 600. There are 40 or 50 carotenoids in the typical diet of human beings, but only 14 major dietary ones are identified in human plasma. Lutein, in particular, is a vitamin that is found naturally in the retina, especially in the macula, the region of the eye that is essential for fine, detailed vision. Previous studies have shown that higher levels of foods rich in Omega-3 fatty acid were associated with a lower likelihood of AMD. Patients ages 60 and older who may or may not have AMD, who do not have certain other serious eye disorders, and who have not had potentially life-threatening illness in the last year may be eligible for this study. About 40 people will participate. Patients will undergo a medical history and physical examination. A blood collection of about 4 tablespoons will be done to measure the amount of lutein and other vitamins in the blood. Patients will have a complete eye examination consisting of procedures standard to those given by ophthalmologists. Participants will have photographs taken of their eyes, and they will undergo a visual field test. Flicker photometry also will be conducted. This consists of the patients looking at a flashing bluish light with one eye at a time, and turning a knob until the light stops flashing. Then during the test, patients will look away from the light and turn the knob until the flashing stops. During this study study, patients will be asked to not take more than two tablets each day of multivitamins that contain lutein. The vitamin supplements will be provided as pills that represent one of two vitamin regimens given on a random basis: either lutein and zeaxanthin with DHA or lutein and zeaxanthin without DHA added. The amounts would be 10 mg/day of lutein and 2 mg/day of zeaxanthin, with or without 1 g/day of DHA. Patients will return to the study center for follow-up visits at 1 month, 3 months, 6 months, and 9 months. During those visits, some of the examinations done earlier will be repeated so that the researchers can evaluate the effects of supplements on patients' eyes. Patients will also be watched for possible side effects from the vitamins supplements. Lutein and zeaxanthin supplements are considered to be safe with possible minor side effects, such as headaches and difficulty in swallowing the tablets. Fish oil or DHA supplements may also cause abdominal discomfort. If information obtained from this study may be important for participants' health, they will be informed when it is available. There are no plans to give participants the results of any medical tests, evaluations, or other research data. Further research may be necessary before such results become meaningful.
The purpose of this study is to demonstrate that Visudyne therapy in patients who have occult with no classic subfoveal choroidal neovascularization (CNV) lesions will, with an acceptable safety profile, significantly reduce the risk of vision loss compared with placebo (sham treatment).
