      Gene Therapy (ADVM-022) for Age-Related Macular Degeneration

      Morgantown, West Virginia
      Neovascular or wet age-related macular degeneration (nAMD) is a degenerative ocular disease associated with the infiltration of abnormal blood vessels in the retina from the underlying choroid layer and is a leading cause of blindness in patients over 65 years of age. The abnormal angiogenic process in nAMD is stimulated and modulated by vascular endothelial growth factor (VEGF). Treatment of nAMD requires frequent intravitreal (IVT) injections of VEGF inhibitors (anti-VEGF) administered every 4-16 weeks. ADVM-022 (AAV.7m8-aflibercept) is a gene therapy product being developed for the treatment of nAMD and offers the potential for sustained intraocular expression of aflibercept following a single IVT injection. ADVM-022 is designed to reduce the current treatment burden which often results in undertreatment and vision loss in patients with nAMD receiving anti-VEGF therapy in clinical practice.

      Active tDCS for Age-Related Macular Degeneration

      Waterloo, Ontario
      The purpose of this study is to test whether a kind of brain stimulation called anodal transcranial direct current stimulation (a-tDCS) can be combined with perceptual learning to improve the ability of people with age-related macular degeneration (AMD) or juvenile macular degeneration (JMD) to read words presented to them on a computer screen better than if perceptual learning alone were used. In addition, secondary measures of visual acuity will also be examined to determine whether brain stimulation can allow patients to resolve finer details of an image. The proposed treatment is the application of a-tDCS onto the participant's head, with brain stimulation aimed at Primary Visual Cortex toward the occipital pole, while patients undergo six separate sessions of training. The investigators will test the ability of participants to read words before the start of the training sessions (pre test) and after the completion of all training sessions (post test). This is a between-subjects design, and half of the participants will receive true stimulation, and the other half will receive sham stimulation. The difference between the pre and post tests when receiving active stimulation will be compared to the difference when receiving sham stimulation, because the sham stimulation is not expected to influence reading beyond a placebo. The aim of the study is to examine the potential of concurrent brain stimulation and perceptual learning as an effective treatment for macular degeneration that may be used in conjunction with more traditional eye-based interventions. The investigators hypothesize that the brain stimulation will enable higher performance in the reading task after and secondary measures after perceptual training due to an increase in the cortical excitability of the stimulated brain cells.

      NSAID vs Steroid-NSAID Combo for Glaucoma

      Hamilton, Ontario
      This clinical trial, led by Dr. Enitan A. Sogbesan at the Hamilton Regional Eye Clinic, St. Joseph's Healthcare Hamilton, aims to compare the efficacy and safety of non-steroidal anti-inflammatory drug (NSAID) ketorolac alone versus a combination of ketorolac and the corticosteroid fluorometholone, and a control group receiving no postoperative treatment. The trial will evaluate these treatment strategies following Selective Laser Trabeculoplasty (SLT) in patients with open-angle glaucoma. The primary objective is to determine the most effective postoperative management strategy to reduce inflammation, improve patient comfort, and control intraocular pressure (IOP). Participants will be randomly assigned to one of the three groups, with follow-up visits scheduled at 1 hour, 1 week, 1 month, 3 months, 6 months, and 1 year post-SLT. The study's findings aim to guide clinicians in optimizing postoperative care for better patient outcomes.

      High-Speed Eye Scanning Technology for Retinopathy of Prematurity

      Durham, North Carolina
      Retinopathy of prematurity (ROP) is a disorder of development of the neural retina and its vasculature that can impact vision in vulnerable preterm neonates for a lifetime. This study tests high-speed optical coherence tomography (OCT) technology compared to conventional color photographs at the bedside of very preterm infants in the intensive care nursery, to characterize previously unseen abnormalities that can predict a need for referral for ROP treatment, or poor visual or neurological development later in life, up to pre-school age. Our long-term goal is to help improve preterm infant health and vision via objective bedside imaging and analysis that characterizes early critical indicators of ROP, and poor visual function and neurological development, which will rapidly translate to better early intervention and improved future care.

      AI-Based Screening for Glaucoma

      Birmingham, Alabama
      The goal of this clinical trial is to learn if implementation of an eye screening program at Federally Qualified Health Center (FQHC) clinics provides results that participants may have glaucoma, and/or other eye conditions (diabetic retinopathy, cataract, visual acuity impairment). The glaucoma screening will incorporate use of an artificial intelligence (AI)-assisted screening tool. This project is called AI-RONA. The main questions it aims to answer are: * How does this eye screening program compare to the rate of glaucoma and other eye conditions detected at other FQHC clinics where the screening program has not been implemented? * Do particpants who screen positive for these conditions adhere to the physician's recommendation for a follow-up examination by an optometrist or ophthalmologist? * Are referral rates for a follow-up comprehensive eye exam by an optometrist or ophthalmologist similar to those implemented by an ophthalmologist using telemedicine (that is, using the results of the screening to make a diagnosis remotely)? * What is the cost-effectiveness of the AI-assisted screening program in diagnosing glaucoma as compared to a physician-guided program? * Are participants completing the screening satisfied with it? * Are physicians at the FQHC clinics administering the screening satisfied with it? Participants will: * Undergo an ocular screening whose goal is to detect glaucoma, diabetic retinopathy, cataract, and/or impairment in visual acuity. If the screening indicates that participants may have these conditions, participants will be referred for a comprehensive eye examination by an optometrist or ophthalmologist. * Following the screening, participants and physicians will complete a survey on their satisfaction with the program.

      Surgical Techniques + Gas Tamponade for Retinal Detachment

      Québec, Quebec
      Background: Few large randomized controlled trials provide strong evidence to guide surgical repair of primary rhegmatogenous retinal detachment (RRD) repair. The purpose of this factorial, single-blind, randomized controlled trial is to analyze and compare the surgical outcomes, functional visual outcomes, complications, and quality of life associated with RRD repair using (A) pars plana vitrectomy only (PPV) or PPV with scleral buckle (PPV-SB) and (B) sulfur hexafluoride gas (SF6) or perfluoropropane gas (C3F8) tamponade. Methods: Eligible patients with moderately complex RRD will be randomized 1:1 to PPV or PPV-SB and 1:1 to SF6 or C3F8 gas tamponade. Approximately 560 patients will be recruited to be able to detect a difference of around 10% in SSAS rate between groups. Patients will be followed using multimodal imaging and quality of life questionnaires before and after the surgical repair until 1 year postoperative. The primary outcome will be single surgery anatomic success (SSAS), defined as absence of reoperation for recurrent RRD in the operating room. Secondary outcomes will be pinhole visual acuity (PHVA) at 8-10 weeks and 6 months, final best-corrected visual acuity (BCVA), final retina status (i.e., attached or detached), time to onset of RRD recurrence, severity and number of complications, and questionnaire results. Discussion: This will be the first 2 × 2 factorial randomized controlled trial examining repair techniques in primary RRD. It will also be the first randomized controlled trial to compare gas tamponade between the two most common agents. Notably, it will be adequately powered to detect a clinically significant effect size. The use of multimodal imaging will also be a novel aspect of this study, allowing us to compare head-to-head the impact of adding an SB to the retina's recovery after RRD repair and of differing gas tamponades. Until now, the treatment of RRD has been largely guided by pragmatic retrospective cohort studies. There is a lack of strong evidence guiding therapeutic decisions and this trial will address (1) whether supplemental SB is justified and (2) whether longer duration gas tamponade with C3F8 is necessary.

      Balance Improvement Intervention for Vestibular Hypofunction

      Missoula, Montana
      The proposed research is relevant to vestibular science and the general public because age-related vestibular hypofunction is a major contributor to poor balance, falls, and other adverse health outcomes. In this investigation the investigators will: 1) assess the preliminary efficacy of a novel intervention system for improving vestibular function and dizziness in community-dwelling older adults, 2) assess the safety and feasibility of the this system, and 3) assess the acceptability and implementation potential of this system, prior to a large-scale, R01-level investigation.

      "I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

      "My orthopedist recommended a half replacement of my right knee. I have had both hips replaced. Currently have arthritis in knee, shoulder, and thumb. I want to avoid surgery, and I'm open-minded about trying a trial before using surgery as a last resort."

      "I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

      Why We Started Power

      We started Power when my dad was diagnosed with multiple myeloma, and I struggled to help him access the latest immunotherapy. Hopefully Power makes it simpler for you to explore promising new treatments, during what is probably a difficult time.

      Frequently Asked Questions

      How much do Visual Acuity clinical trials pay?

      Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

      How do Visual Acuity clinical trials work?

      After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Visual Acuity trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Visual Acuity is 12 months.

      How do I participate in a study as a "healthy volunteer"?

      Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

      What does the "phase" of a clinical trial mean?

      The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

      Do I need to be insured to participate in a Visual Acuity medical study?

      Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

      What are the newest Visual Acuity clinical trials?

      Most recently, we added FaceScan for Measuring Visual Acuity, Valproate for Lazy Eye and AI-Based Screening for Glaucoma to the Power online platform.
