Filter by:The purpose of this study is to evaluate the effect of intravitreal injections of Macugen every 6 weeks for the treatment of macular edema secondary to branch retinal vein occlusion (BRVO). We hypothesize that macular edema secondary to BRVO is mediated by VEGF 165 and that chronic suppression of VEGF 165 will successfully treat BRVO related macular edema.
The purpose of this study is to examine the effects of Lucentis for active Central Retinal Vein Occlusion with Macular Edema
The purpose of this study is to determine the safety and tolerability of MS-R001 at escalating doses in patients with diabetic macular edema secondary to diabetic retinopathy
This study will evaluate the clinical efficacy of intra-vitreal injections of Ranibizumab (Lucentis) in the treatment of Diabetic Macular Edema as compared to grid/focal laser.
This was an open-label, multicenter, extension study of intravitreally administered ranibizumab in two cohorts. The first cohort (reported here) enrolled patients with primary or recurrent Choroidal Neovascularization (CNV) secondary to Age-Related Macular Degeneration (AMD) who completed the treatment phase of a Genentech sponsored study (FVF2598g (NCT00056836), FVF2587g (NCT00061594), or FVF2428g (NCT00056823)). The second cohort enrolled patients with macular edema secondary to Retinal Vein Occlusion (RVO) who completed the 6-month treatment and 6-month observation phases (12 months total) of a Genentech sponsored study (FVF4165g (NCT00486018) or FVF4166g (NCT00485836)). The results of the second cohort are reported separately (NCT01442064). The first cohort of this study enrolled two subsets of patients: ranibizumab experienced and ranibizumab-naive. Patients were enrolled within 14 days of completion of the 24 month treatment phase of the previous study.
Macular edema constitutes the primary cause of visual impairment in diabetic patients with a disease duration of 20 years or more. Intravitreal triamcinolone (IVTA) and macular focal laser photocoagulation were reported to generate favorable results in the treatment of diabetic macular edema, but there have been patients with diffuse diabetic macular edema refractory to such treatment modalities. The present study will test the safety and the efficacy of the combined treatment of vitrectomy, IVTA and macular focal laser photocoagulation in the treatment of intractable diffuse diabetic macular edema.
To determine the efficacy and safety of intravitreal triamcinolone acetonide for refractory diabetic macular edema.
The study involves the enrollment of patients over 18 years of age with diabetic macular edema involving the center of the macula who have not already been given maximal laser treatment. Patients with one study eye will be randomly assigned (stratified by prior laser) with equal probability to one of five treatment groups: 1. Focal laser photocoagulation (modified ETDRS technique) 2. Posterior peribulbar injection of 40 mg triamcinolone (Kenalog) 3. Anterior peribulbar injection of 20 mg triamcinolone 4. Posterior peribulbar injection of 40 mg triamcinolone followed after one month by laser 5. Anterior peribulbar injection of 20 mg triamcinolone followed after one month by laser For patients with two study eyes (both eyes eligible at the time of randomization), the right eye (stratified by prior laser) will be randomly assigned with equal probabilities to one of the five treatment groups listed above. If the right eye was assigned to laser only, then the left eye will be assigned to one of the four triamcinolone groups above with equal probability (stratified by prior laser). If the right eye was assigned to receive triamcinolone, then the left eye will receive laser only. Triamcinolone acetonide will be the corticosteroid utilized in this study. The triamcinolone acetonide preparation to be used is Kenalog. Kenalog is manufactured by Bristol Myers Squibb and is approved by the Food and Drug Administration for intramuscular use for a variety of indications. Peribulbar injections of Kenalog have been used for a wide variety of ocular conditions, particularly uveitis and post-cataract extraction cystoid macular edema, for many years. Two different triamcinolone regimens will be assessed in the study: 40 mg injected posteriorly and 20 mg injected anteriorly. There is no indication of which treatment regimen will be better. Although the injection behind the eye is more common than the injection near the front of the eye, the injection near the front of the eye has less risk of injuring the eye. However, it is possible that the injection near the front of the eye may increase eye pressure more frequently. Little is known about which of the two injections decreases macular edema and improves vision more often. Patients enrolled into the study will be followed for three years and will have study visits 1 month, 2 months, 4 months, 8 months and annually after receiving their assigned study treatment. For the first 8 months of the study, patients should only be retreated with their randomized treatment. However, if the patient's visual acuity has decreased by 15 letters or more, then any treatment may be given at the investigator's discretion. After completion of the 8-month visit, treatment is at investigator discretion. The primary objective of this study is to obtain estimates of efficacy and safety outcomes for each of the treatment groups. These estimates will provide a basis for the sample size estimation and hypothesis generation in a phase III trial.
The study involves the enrollment of patients over 18 years of age with diabetic macular edema(DME). Patients with one study eye will be randomly assigned (stratified by visual acuity and prior laser) with equal probability to one of the three treatment groups: 1. Laser photocoagulation 2. 1mg intravitreal triamcinolone acetonide injection 3. 4mg intravitreal triamcinolone acetonide injection For patients with two study eyes (both eyes eligible at the time of randomization), the right eye (stratified by visual acuity and prior laser) will be randomly assigned with equal probabilities to one of the three treatment groups listed above. The left eye will be assigned to the alternative treatment (laser or triamcinolone). If the left eye is assigned to triamcinolone, then the dose (1mg or 4 mg) will be randomly assigned to the left eye with equal probability (stratified by visual acuity and prior laser). The study drug, triamcinolone acetonide, has been manufactured as a sterile intravitreal injectable by Allergan. Study eyes assigned to an intravitreal triamcinolone injection will receive a dose of either 1mg or 4mg. There is no indication of which treatment regimen will be better. Patients enrolled into the study will be followed for three years and will have study visits every 4 months after receiving their assigned study treatment. In addition, standard of care post-treatment visits will be performed at 4 weeks after each intravitreal injection.
This study will evaluate the safety and efficacy of an intravitreal insert of fluocinolone acetonide for the treatment of diabetic macular edema.
