29 Clinical Trials for Various Conditions
During the last 25 years, OCT has become one of the most common imaging technologies used to diagnose and monitor retinal diseases, including AMD. The OCT self-imaging capabilities of the Notal Vision Home OCT (NVHO) system for retinal fluid visualization in the central 10 degrees were validated during several prospective clinical studies1,2,3,4,5. This study is designed to evaluate the retinal fluid exposure of eyes with NV-AMD, using the NVHO system to guide therapy.
The purpose of this study is to evaluate the ability of subjects with NV-AMD to perform sequential daily self-imaging of their eyes with the self-operated Notal Home OCT device in their homes for 90 days without on-site supervision. The study will include up to 15 subjects.
The purpose of this study is to determine the efficacy in the use of topical Squalamine Lactate Ophthalmic Solution, 0.2% in the treatment of retinal neovascularization resulting from proliferative diabetic retinopathy.
This Phase 1 clinical research study will examine the safety and tolerability of an experimental gene transfer agent, AAV2-sFLT01, in patients with Neovascular Age-Related Macular Degeneration (AMD).
The purpose of this study is to evaluate the efficacy and safety of brolucizumab compared to panretinal photocoagulation laser (PRP) in patients with proliferative diabetic retinopathy (PDR). This evaluation will provide information that brolucizumab is non-inferior to PRP with respect to the change in best corrected visual acuity at Week 54.
A Phase 3 Study of the Efficacy and Safety of Squalamine Lactate Ophthalmic Solution 0.2% Twice Daily in Subjects with Neovascular Age-Related Macular Degeneration. Patients will receive injections of ranibizumab. In addition, patients will receive either Squalamine lactate 0.2% eye drops or Placebo eye drops. The study duration is approximately 9 months to primary endpoint
The object of the study is to compare treatment of iris/angle neovascularization with panretinal photocoagulation (laser) to treatment with panretinal photocoagulation and an anti-angiogenic drug: ranibizumab.
A Phase 3, Randomized, Double-Masked, Active-Controlled Trial in Adults with Macular Neovascularization Secondary to Age-Related Macular Degeneration
The main purpose is to find a better way to predict the timing of treatments given to patients with Wet Age-related macular degeneration using image analysis.
The objective is to evaluate the safety of intravitreal Fovista® (anti-PDGF BB) administered in combination with anti-VEGF therapy.
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
The use of intravitreal injections of corticosteroid (triamcinolone acetonide) appears to be a promising treatment for a variety of ocular diseases associated with inflammation. To date, the only drug available, "Kenalog-40 Injection" produced by Bristol Myers Squibb, has not been formulated for intraocular use. The purpose of this study is to evaluate the long-term safety and potential efficacy of novel intravitreal injections of a preservative-free formulation of triamcinolone acetonide (TAC-PF) at two dosage levels (4 mg and 8 mg) compared to anterior sub-tenon injections of TAC-PF at 20 mg. The study will be a masked, randomized Phase I study that will enroll 120 participants with one of the following diseases: age-related macular degeneration (AMD), diabetic macular edema (DME), central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), or any other retinal disease with associated macular edema. At least 21 participants will be enrolled in the four designated disease strata: AMD, DME, CRVO, and BRVO. The remaining 36 participants may have one of these diseases or may be enrolled with another retinal disease. Within each disease strata, at least seven participants will be randomized to each dosing group. The participants will be randomly assigned to one of the three treatment groups. The primary outcome will be an assessment of post-injection intraocular toxicity-related events during the 3-year follow-up, including cataract formation, development of glaucoma, and any adverse event preventing retreatment. The secondary outcomes will be an improvement in best-corrected visual acuity (BCVA, EVA) and decreases in retinal thickening and area of leakage, from baseline to year 1.
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.
This is a research study to evaluate the effects of repeated intravitreal injections on bacteria around the eye.
This is a multicenter, randomized, open-label study. 40 patients will be followed for a period of 12 months. All consented and enrolled patients will receive either 0.5mg or 2.0mg of intravitreal ranibizumab injection.
ABBV-RGX-314 (also known as RGX-314) is being developed as a novel one-time gene therapy for the treatment of neovascular (wet) age-related macular degeneration (wet AMD or nAMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-vascular endothelial growth factor (anti-VEGF) therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to maintain or prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every 4 to 16 weeks in frequency, to maintain efficacy. Due to the burden of these treatments, patients often experience a decline in vision with reduced frequency of treatment over time.
This study is designed to evaluate the safety, tolerability and clinical activity of RXI-109 administered by intravitreal injection to reduce the progression of subretinal fibrosis in subjects with advanced neovascular age-related macular degeneration (NVAMD).
The purpose of this first-in-human study is to evaluate the safety, pharmacokinetics (PK) and pharmacodynamics of OPT-302 administered as monthly intravitreal injections for 3 months with and without Lucentis™ in patients with wet age related macular degeneration (AMD). This study will be conducted in two parts: Part 1 will comprise an open label, sequential dose escalation and Part 2 a randomized dose expansion. OPT-302 is a soluble form of VEGFR-3 comprising the extracellular domains 1-3 of human vascular endothelial growth factor receptor (VEGFR)-3 and the Fc fragment of human IgG1. It functions by binding and neutralizing the activity of vascular endothelial growth factor (VEGF)-C and VEGF-D on endogenous VEGFR-2 and VEGFR-3. VEGF-C and VEGF-D promote blood vessel development (angiogenesis) by binding and activating VEGFR-2 and VEGFR-3. VEGF-C is also a potent inducer of vascular permeability or leakage. Angiogenesis and vascular leakage are key hallmarks of wet AMD. Approved therapies for wet AMD include Eylea™ and Lucentis™ which block the activity of VEGF-A, but not VEGF-C or VEGF-D which are alternate members of the same family of molecules. VEGF-C and VEGF-D can stimulate blood vessel growth and leakage through the same pathway as VEGF-A (via VEGFR-2), as well as through pathways that are independent of VEGF-A (via VEGFR-3). Published studies have also indicated that VEGF-C and VEGF-D play an important role in mediating resistance to therapies that block VEGF-A such as Lucentis™ and Eylea™. Combination therapy with OPT-302 an anti-VEGF-A agent provides a more complete blockade of the VEGF family. This strategy targets functional redundancy in the VEGF pathway and mechanisms of 'resistance' or sub-response to VEGF-A inhibition.
The study will investigate the safety and feasibility of using the TheraSight(TM) Brachytherapy System for treatment of wet age-related macular degeneration (AMD).
This screening protocol is designed to help recruit patients for National Eye Institute (NEI) studies of the retina, such as diabetic retinopathy and macular degeneration. Patients must meet the specific criteria of a research study, and this protocol serves as a first step for admitting patients to a retinal disease study. Candidates will undergo a medical history and comprehensive eye examination. The eye examination includes dilation of the pupils to fully examine the retina. In some studies, photographs of the eye are required. This is done using fluorescein angiography. In this procedure, a dye called sodium fluorescein is injected into the blood stream through a vein. After the dye reaches the blood vessels of the eye, photographs are taken of the retina. Other diagnostic procedures may include physical examination, questionnaires, routine laboratory tests and other standard or specialized tests, as needed. When the screening is completed, patients will be informed of their options to participate in a study. Patients who are ineligible for a current study will be informed of alternative treatments or options. No treatment is offered under this protocol.

This Phase 3 study will evaluate the efficacy and safety of KSI-301 compared to aflibercept, in participants with neovascular (wet) age-related macular degeneration (wAMD)
ADVM-022-07 is an observational long-term extension (OPTIC-EXT) study assessing safety and efficacy of ADVM-022 gene therapy product, in subjects with neovascular, or exudative (wet), age-related macular degeneration (nAMD).
The purpose of this extension study was to evaluate the efficacy and safety of brolucizumab used in a Treat-to-Control-regimen for treatment of patients with neovascular age-related macular degeneration who have completed the CRTH258A2303 (TALON) study. The main objective was to assess brolucizumab's potential for long durability up to 20 weeks. All eligible participants were treated with brolucizumab regardless of their treatment in the TALON study. The study period was 56 weeks including post-treatment follow-up.
This study will evaluate the efficacy, safety, durability, and pharmacokinetics of KSI-301 administered at 12, 16 and 20 weeks intervals as specified in the protocol, compared with aflibercept once every 8 weeks (Q8W), in participants with treatment-naïve neovascular (wet) age-related macular degeneration (nAMD).
This was a 64-week randomized, double-masked, multi-center, active-controlled, two-arm study in patients with neovascular age related macular degeneration (nAMD) who have not previously received anti- vascular endothelial growth factor (VEGF) treatment.
Clinical and genetic evaluation of individuals treated with intravitreal aflibercept injection (Eylea) for neovascular age-related macular degeneration (wet AMD)
The study is an Observational, Phase 0 designed to establish that the risk for diabetic retinopathy assigned by the RiskAnalyzer improves the reading accuracy and consistency of any reader and it decreases the inter-reader variability. Objectives: Objectives one, two, and three are arranged chronologically and in an increasing level of complexity as a three tiered approach to support the primary and secondary endpoint of the trial. Objective one is to test fully each system components of the study limited to a single site. Objective two is to evaluate the efficacy of the RiskAnalyzer to assign the risk of Diabetic Retinopathy in comparison to the gold standard. Objective three is to demonstrate that the reader's accuracy in grading images is improved when risk levels assigned by the RiskAnalyzer are made available to the reader while performing the grading of the images which is the primary endpoint of the trial Methods and Research Design: A network of clinical study sites will be established to meet the required number of cases needed as calculated by statistical analysis. Male and Female Subjects between the ages of 18-65 who are either pre-diabetic or diabetics will be eligible for participation in this study. Subjects will be recruited, consented, photographed and their images graded by two trained readers and analyzed by the RiskAnalyzer . The risk levels that are obtained from the RiskAnalyzer will be compared to the current gold standard practice, manual grading of each case by a reader. Data collected during this clinical trial will be reported to the referring physician in the form of a retinal screening report completed and signed by a licensed Ophthalmic professional and delivered to their attending physician. Risk levels for diabetic retinopathy obtained by use of the RiskAnalyzer will not be given to the attending physician under any circumstances in order to preserve standard of care for the patient. The sensitivity, specificity, receiver operating characteristic (ROC), and data flow process of the RiskAnalyzer, retinal image reading system will be analyzed and based on the current gold standard of a human reader. This study is a three-aims study, 24 month in length, prospective, case-only study of the performance of the RiskAnalyzer. The risk levels obtained from the RiskAnalyzer are not made visible, i.e. are not unmasked to either of the two readers. In year two, the risk levels obtained from the RiskAnalyzer for half of the studies are unmasked to the two readers while grading the image. Access to all study data and processes follows a role-based design. The clinical staff will have access only to clinical data but not the technical data. The technical team will have access to the technical data only but not the clinical data. The study coordinator will have access to all data. The use of computers will adhere to the Guidance for Industry Computerized Systems Used in Clinical Investigations and applicable sections of 21 CFRs part 11.
This is a prospective pilot study to evaluate the usability and applicability of a self monitoring test of visual function with the handheld Health Management Tool (HMT) to remotely monitor neovascular Age Related Macular Degeneration (AMD) to detect a potential change in disease status.
