Researchers are exploring new treatment options for neovascular age-related macular degeneration NVAMD, a condition affecting the eyes. This trial aims to compare a new medicine called tiespectus also known as MK-8748 or EYE201 with the standard treatment aflibercept to see if tiespectus works as well in treating NVAMD. The study includes adults aged 50 and older who have not previously received treatment for this condition. Participants will be randomly assigned to one of three groups tiespectus low dose, tiespectus high dose, or aflibercept. Those in the tiespectus groups will receive three initial injections every 4 weeks, followed by injections every 8 weeks up to week 48. After week 48, treatment will continue at intervals based on individual response until week 92. The aflibercept group will receive three initial injections followed by injections every 8 weeks until week 92. During the study, participants will have their vision tested using the Best-Corrected Visual Acuity BCVA score and their eye structure examined with imaging techniques. Researchers will monitor changes in vision over one year and track any side effects up to approximately 96 weeks. Participants will attend regular visits for treatment and assessments throughout the study period lasting about 92 weeks.

Researchers are evaluating the safety and preliminary effectiveness of THN391 in people with diabetic macular edema DME related to non-proliferative diabetic retinopathy. This Phase 1b study focuses on how different doses of THN391 affect vision and retinal swelling in this eye condition. Participants will be enrolled into three groups receiving escalating doses of THN391 through intravitreal IVT injections. Each participant will receive three monthly injections of THN391 at low, medium, or high doses. The study is open-label and sequential, meaning all participants and researchers know the treatment given, and dosing increases with each group. During the study, participants will be monitored for adverse events for up to 16 weeks after their first injection. Researchers will also measure changes in visual acuity and retinal edema to assess treatment effects. Participation involves multiple visits for injections and assessments over approximately 4 months.

Researchers are studying the use of VX-01, an oral medication, to treat people with moderate to severe Non-Proliferative Diabetic Retinopathy NPDR, a condition related to diabetes affecting the eyes. This Phase 2 clinical trial aims to evaluate how effective and safe VX-01 is compared to a placebo over one year of treatment, including how the body processes the drug and its effects on the disease. Participants will be randomly assigned to one of two groups one group will receive VX-01 tablets at a dose of 150 mg twice daily, and the other group will receive placebo tablets twice daily. The treatment period lasts 52 weeks, followed by a 12-week follow-up after treatment ends. The study is double-masked, meaning neither participants nor study staff know which treatment is being taken during the trial. During the study, participants will have their vision and eye health regularly assessed using standardized tests such as the Early Treatment Diabetic Retinopathy Study ETDRS letter score and diabetic retinopathy severity scores. Safety will be monitored by tracking any adverse events. Participants must attend scheduled visits for evaluations and agree to avoid other investigational studies during the trial. The main goal is to see how VX-01 affects diabetic retinopathy after one year of daily treatment.

Researchers are evaluating FWY003 in adults aged 50 and older with geographic atrophy GA caused by age-related macular degeneration AMD. The study aims to understand the relationship between different doses of FWY003 and their effects on the size of GA lesions, as well as the safety and overall effectiveness of the treatment compared to a placebo. This is a randomized, multi-center, double-masked Phase 2 trial designed to gather detailed information about dosing and outcomes. Participants are randomly assigned to one of four groups receiving either one of three dose levels of FWY003 or a placebo. The treatment period lasts 18 months, during which doses are administered and monitored regularly. The study includes extensive assessments of visual function using various eye tests and imaging to measure changes in GA lesion areas. Blood samples are also collected to measure FWY003 levels. Throughout the study, participants undergo periodic evaluations including eye exams, imaging, and visual acuity tests to track changes in their condition and monitor for any adverse effects. Safety is closely observed from the first dose through month 19. The primary measurement is the change in GA lesion size over 18 months. Participants are followed for the full duration of the trial, which lasts until 2029, ensuring comprehensive monitoring of treatment effects and safety.

Researchers are evaluating ways to improve hepatitis C virus HCV care in drug treatment clinics and needle and syringe programs in New South Wales and across Australia. The ETHOS II Project aims to develop a framework to establish HCV screening and treatment programs in these settings nationally. This collaborative research involves several health organizations and focuses on people with a history of injecting drug use or those receiving opioid substitution therapy. The study includes an intervention called campaign days where participants receive hepatitis C screening, liver fibrosis assessments using fibroscans, and clinical assessments. Participants also complete surveys and may consent to link their data with population databases. A sub-study involves collecting blood samples from some participants to evaluate new diagnostic tests for chronic HCV infection. Additionally, interviews with policymakers, clinicians, and patients will explore barriers to HCV care, and an education program will be developed to improve workforce knowledge and care quality. Participants will be recruited from drug treatment clinics, general practitioners with high case loads, and needle and syringe programs. They will undergo hepatitis C testing, fibroscans, clinical assessments, and complete questionnaires during the campaign days. Researchers will track how many participants start anti-HCV treatment each year for up to three years. The study also includes follow-up through medical record reviews to monitor outcomes and improve treatment access and delivery.

Researchers are evaluating the effectiveness of ADX-038 compared with a placebo in people aged 60 and older who have geographic atrophy GA caused by age-related macular degeneration AMD. This Phase 2 study also aims to assess the safety, how the body processes the drug pharmacokinetics, and how the drug affects the body pharmacodynamics. Participants will be randomly assigned to receive either the active drug ADX-038, which is a siRNA duplex oligonucleotide, or a saline placebo through subcutaneous treatment. The study follows a parallel design with quadruple masking to compare the effects of the treatments over time. During the study, participants will attend clinic visits for various assessments including imaging to evaluate the preservation of the ellipsoid zone EZ layer in the eye over 12 months. The study team will monitor safety and adherence, and participants must complete meningococcal and pneumococcal vaccinations as required. The total study duration extends until 2030, with the primary outcome measured at 12 months.
