101 Clinical Trials for Various Conditions
This was a Phase II, multicenter, randomized, active comparator-controlled, 52-week study to investigate the efficacy, safety and pharmacokinetics of faricimab (RO6867461; RG7716) administered with extended dosing regimens in treatment-naive participants with neovascular age related macular degeneration (nAMD). Only one eye was chosen as the study eye.
The overall goal of the proposed research project is to provide evidence that a specific subtype of neovascularization that may develop in eyes with age-related macular degeneration (AMD) prevents vision loss. This concept challenges the current view that the development of neovascularizations in AMD represents a harmful event in general. Notably, before the era of anti-vascular endothelial growths factor (VEGF) therapy, destruction and surgical removal of neovascular membranes have been tested as treatment options for neovascular AMD. This research project aims to substantiate the hypothesis that type 1 macular neovascularization (MNV) is intrinsically protective, in sense of a positive response to the degenerative processes in AMD. This concept has actually been proposed by pathologists decades ago but has not been systematically investigated in vivo. With the immense advances in retinal imaging, 'sub-clinical', non-exudative type 1 MNVs that are located beneath the retinal pigment epithelium (RPE) can now be detected non-invasively and characterized in vivo. There is currently a growing body of evidence that photoreceptor and RPE degeneration is indeed slowed down in eyes exhibiting type 1 MNV. However, the proof of a direct protective effect of non-exudative type 1 MNV on visual function in AMD is lacking. Here, the aim is to demonstrate relative preservation of function along with preserved structure in the immediate vicinity of type 1 MNV, while there is progressive loss of sensitivity and degeneration in the surrounding tissue.
The purpose of this study is to evaluate the safety and effects of repeated intravitreal injections of ICON-1 0.6 mg administered as maintenance therapy or in combination with aflibercept in patients with wet macular degeneration.
This multiple-center, multiple-dose and regimen, randomized, double-masked active comparator-controlled, double-masked, five parallel group, 36-week study will evaluate the efficacy, safety, tolerability, and pharmacokinetics of faricimab (RO6867461) in participants with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The study was designed to allow the evaluation of RO6867461 in a treatment-naive population (comparison of Arms A, B, C, and D) and an anti-VEGF-incomplete responder population that met a predefined criterion at Week 12 (comparison between Arms A and E). Only one eye per participant was chosen as the study eye.
The purpose of this study is to evaluate the safety, biological activity and pharmacodynamic effect of repeated intravitreal doses of hI-con1 0.3 mg administered as monotherapy and in combination with ranibizumab 0.5 mg compared to ranibizumab 0.5 mg monotherapy in treating patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).
We propose to undertake a retrospective review of approximately 200 patients with a diagnosis of exudative macular degeneration treated with triple combination therapy (Bevacizumab, Dexamethasone and Photo-dynamic therapy) during the years of 2006 to 2010 at The Retina Center and compare those results with an additional group of approximately 200 patients also treated with triple combination therapy and 20 mg of daily oral zeaxanthin.
Prospective, multi-center 2-stage study. Stage 1 (Phase I) is open-label with all patients treated with the NT-503-3 ECT implant. Stage 1 (Phase I) patients will undergo explantation at year 2. Those who, in the opinion of the investigator, are still candidates for continued anti-VEGF therapy will be re-implanted with a new NT-503-3 investigational product and followed for an additional 12 weeks before study exit. Stage 2 (Phase II) is a separate, randomized, masked phase during which eligible patients will be randomized to the NT-503-3 group or the control group. Clinical Hypotheses: * NT-503-3 ECT is comparable to Eylea® injected intravitreally every 8 weeks in the prevention of vision loss due to recurrent CNV secondary to AMD * NT-503-3 ECT has an acceptable safety profile
This study will evaluate the safety and efficacy of dexamethasone (OZURDEX®) as adjunctive therapy to ranibizumab (LUCENTIS®) compared with ranibizumab alone in the treatment of patients with choroidal neovascularization secondary to age-related macular degeneration
The purpose of this study is to evaluate the safety and effectiveness of intravitreal ranibizumab (Lucentis) in patients with fluid and blood leakage in their eyes due to ocular histoplasmosis.
The aim of the study is to evaluate whether PF-04523655 is safe in the treatment of neovascular/wet AMD
Injections of medicine into the middle of the eye (intravitreal injections) are commonly used in a multitude of retinal diseases. We are looking for new treatments that may be beneficial in treating retinal disease and improving patients' vision. Infliximab (Remicade) is a genetically engineered antibody against a molecule in the body called TNF-α. It neutralizes the effects of TNF-α by binding to it. Intravenous Infliximab has been used for inflammatory arthritic conditions and Crohn's disease since 1998. We do not know if infliximab injections into the eye are safe. We are performing this pilot study to determine if they can be safe.
Wet age-related macular degeneration (AMD) is caused by the formation and growth of abnormal blood vessels (angiogenesis) in the retina. The new blood vessels have fragile walls and can leak fluid into the retina. The build-up of fluid (edema) under the macula can distort vision or cause vision loss. TG100801 is a topical (eye drop) therapy that has been shown to inhibit ocular angiogenesis, vascular leak, and inflammation in laboratory studies. The primary purpose of this pilot study is to evaluate the ability of topical administration of TG100801 to reduce the amount of fluid in the retina in patients with AMD following 30 days of treatment. An additional objective is to evaluate the safety of TG100801 in patients with AMD.
CNV from AMD is the leading cause of blindness in people over 50 in North America. The hypothesis is to determine if there is an improvement in retinal function determined by ERG following treatment with ranibizumab for AMD
This study evaluated the effect of combination therapy with verteporfin photodynamic therapy and ranibizumab on visual acuity and anatomic outcomes compared to ranibizumab monotherapy and the durability of response observed in patients with choroidal neovascularization secondary to age-related macular degeneration.
The purpose of this study is to determine the sensitivity of the optical coherence tomography (OCT) test in detecting neovascular AMD in eyes at high risk for CNV development. In order to test this hypothesis, we are conducting a multi-center clinical study at four participating clinical centers. A total of 227 participants will be enrolled. Participants will be followed-up for a period of two years, or until CNV develops in the study eye for which treatment is recommended, to determine the occurrence of CNV. The fundamental design principles of the study are simplicity and parsimony.
The purpose of study is to determine if Lucentis combined with imatinib mesylate will help treatment in patients with newly diagnosed choroidal neovascularization.
The purpose of this study will be to assess the safety and tolerability and dose-limiting toxicity of a single intravitreal injection of Sirna-027 (AGN211745) and to assess the anatomical changes in the retina, changes in CNV, and changes in visual acuity. Escalation to the next dose cohort will be completed following minimum of 2 weeks follow-up. Patients will be monitored intensively for three months, and then followed-up for safety up to 24 months post-injection.
This research is being done to look at the effects of an experimental drug, ranibizumab, on a condition called "predominantly hemorrhagic subfoveal choroidal neovascularization (CNV)" due to wet age-related macular degeneration. A predominantly hemorrhagic CNV lesion is diagnosed when at least 50% of the choroidal neovascular lesion is occupied by blood under the retina. We want to find out if injections of ranibizumab into the eye will help patients with this condition.
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.
This is a phase III, multicenter, randomized, double masked, sham injection-controlled study of the efficacy and safety of intravitreally administered ranibizumab in subjects with subfoveal choroidal neovascularization secondary to age-related macular degeneration.
AG-013,958 is being studied to treat patients with Age-Related Macular Degeneration. A total of 144 subjects may be enrolled in the trial. Subjects will be male or female at least 55 years of age with "wet" age-related macular degeneration.
Age-related macular degeneration (AMD) represents the most common cause of blindness in patients over the age of 60. The major cause of vision loss in this disease is due to the development of choroidal neovascular membrane formation (CNVM). Several clinical trials have proven that eyes with "well-defined" CNVM or lesions that can be readily demarcated with fluorescein angiography can be successfully treated with laser photocoagulation. However, up to 87% of eyes present with "ill-defined" CNVM or lesions that cannot be well demarcated on fluorescein angiography and are not amenable to laser photocoagulation. No beneficial treatment for this form of choroidal neovascularization has been established. Histopathologic study has demonstrated the presence of inflammatory and reparative responses in the retina of patients with ill-defined choroidal neovascularization. Since corticosteroids have been shown to downregulate many of the cellular factors involved in both inflammation and repair, the present study is designed to assess the ability of corticosteroid injection around the eye to prevent severe vision loss associated with "ill-defined" choroidal neovascularization in the setting of age-related macular degeneration. The study will be organized as a randomized open label control clinical trial involving 2 phases. Phase 1 involving 40 patients will establish the feasibility and safety of this treatment modality. Phase 2 will place emphasis on efficacy of the study.
This is a prospective, multi-site, safety and feasibility study of the SalutarisMD SMD-DA system for retrobulbar minimally invasive episcleral brachytherapy device in patients receiving and not responding to anti-VEGF therapy for nAMD. The trial will be open label and non-randomized. The study intervention is a one-time intervention and requires no alteration to the standard of care during the follow-up period.
The purpose of this study is to assess the efficacy and safety of intravitreal injection of aflibercept for the treatment of Choroidal Neovascularization (CNV) secondary to presumed ocular histoplasmosis syndrome (POHS).
This is a two-part study. The first part (Stratum I) is an open-label, dose escalation, safety, tolerability and pharmacokinetic study, where active study drug (PF-04523655) will be given to all patients who participate. Stratum I will determine the maximum tolerated dose and any dose-limiting toxicities. The second part (Stratum II) is a prospectively randomized, multi-center, double-masked, dose ranging study evaluating the efficacy and safety of PF-04523655 alone and in combination with ranibizumab versus ranibizumab alone in patients with DME.
The primary objective: \*To measure the difference in the number of Ranibizumab therapies needed in 12 months in the Posterior Vitreous Detachment (PVD) positive and Posterior Vitreous Detachment (PVD) negative group. Secondary Objective: * To measure the mean change in visual acuity from Baseline to Month 12. * To measure the mean change in central retinal thickness per OCT from Baseline to Month 12
The study will evaluate the safety and efficacy of the intravitreal dexamethasone implant as adjunctive therapy to Anti-VEGF treatment in the study eye of treatment naïve subjects with choroidal neovascularization secondary to age-related macular degeneration. Subjects will be followed for 26 weeks.
The study will evaluate the safety and efficacy of the intravitreal implant of dexamethasone with Anti-VEGF treatment vs. Anti-VEGF alone (with sham dexamethasone injection) in patients with subfoveal choroidal neovascularization secondary to age-related macular degeneration.
The objective of this study is to determine if combination therapy (reduced-fluence Visudyne followed by Lucentis \[within 2 hours\] or either of two regimens of reduced-fluence Visudyne followed by Lucentis-Dexamethasone triple therapy \[within 2 hours\]) reduces retreatment rates compared with Lucentis monotherapy while maintaining similar vision outcomes and an acceptable safety profile.
The purpose of this research study is to compare different timing therapies of Verteporfin with Bevacizumab to treat choroidal neovascularization (CNV) due to age-related macular degeneration (AMD).
