Researchers are investigating the safety and effects of 4D-150 gene therapy in adults aged 50 and older with neovascular (wet) age-related macular degeneration (AMD) who are already receiving anti-VEGF treatment and have shown a clinical response. This Phase 1/2 trial includes dose-escalation and randomized, controlled, masked expansion phases, aiming to evaluate 4D-150 administered by intravitreal injection in one eye, with additional substudies assessing dosing in the second eye and vector shedding. Participants will receive a one-time dose of 4D-150 by injection into the study eye, followed by monthly assessments for 24 months to monitor safety and effectiveness. Those who receive 4D-150 will then enter a long-term follow-up period up to 5 years to assess ongoing safety and the duration of treatment effects. Substudies include one for contralateral eye dosing and another to characterize vector shedding, with participants monitored regularly for safety through one year and continuing long-term follow-up through year 5. Throughout the study, participants will undergo tests of visual and retinal function and structure, with assessments performed monthly initially and safety monitored for up to five years. Researchers will track treatment-emergent adverse events, serious adverse events, and any significant changes in safety parameters. Participants must comply with study procedures and visits, and males receiving 4D-150 will be advised to use barrier methods during intercourse for six months to prevent fluid transmission.

Researchers are evaluating the safety and effectiveness of the drug LY4065967 for treating diabetic peripheral neuropathic pain (DPNP). This study is part of a larger chronic pain master protocol aimed at speeding up the development of new treatments for chronic pain. Participants have diabetic peripheral neuropathy mainly affecting their lower limbs and have had this condition for at least six months. The study compares oral LY4065967 to a placebo, with participants randomly assigned to either group. The trial is a Phase 2, randomized, placebo-controlled clinical trial. Treatments are given by mouth, and participants continue their usual diabetes care with stable treatment for at least 90 days before screening. During the study, researchers monitor changes in average pain intensity using a numeric rating scale from baseline to week 8. Participants undergo assessments including blood sugar control (HbA1c), body mass index measurement, and safety monitoring for heart and vitamin B12 status. The trial is designed for adults aged 18 years and older and includes close observation to ensure participant safety throughout the study period.

Researchers are evaluating the safety and effectiveness of Alpha DaRT-224, a novel treatment for patients with recurrent cutaneous squamous cell carcinoma who have not responded to standard therapies and are not candidates for surgery or standard radiation. This multicenter, pivotal, single-arm, open-label clinical study aims to determine the objective response rate and duration of response following treatment, as well as assess progression-free survival, overall survival, local tumor control, and quality of life. The treatment involves placing DaRT seeds, which contain a radium-224 source that releases alpha-emitting atoms, directly into the tumor. These seeds remain in the tumor for 14 to 21 days before being removed. The procedure is planned using radiotherapy parameters and monitored with volumetric imaging to ensure proper placement and coverage of the tumor. Participants will undergo evaluations including CT scans and blood tests before and during the study. Researchers will measure tumor response from day 14 through 52 weeks after treatment and monitor safety by tracking adverse events related to the device. The study also includes assessments of quality of life and long-term outcomes over several months. Participants are followed closely to document tumor changes, side effects, and overall health during the study period.

Researchers are investigating new treatment options for neovascular age-related macular degeneration (NVAMD), a condition affecting the eyes. Standard treatments like aflibercept do not work for everyone, so this trial is studying a medicine called tiespectus (also known as MK-8748 or EYE201) to see if it can effectively treat NVAMD. This is a pivotal Phase 2/3 randomized, double-masked, multicenter study comparing tiespectus to aflibercept. Participants will receive treatment by intravitreal injection directly into the eye. The study has three groups: one receiving tiespectus, another receiving aflibercept (2 mg), and possibly a third comparator group as part of the design. The study aims to assess the efficacy and safety of these treatments in people newly diagnosed with NVAMD. During the study, participants will be monitored for changes in their best-corrected visual acuity (BCVA) using standard eye charts from the start of the study to one year later. Researchers will perform regular eye exams and safety assessments to track treatment effects. Participation involves follow-up visits over at least one year to evaluate vision changes and treatment safety in detail.

Researchers are evaluating the effects of two different methods of giving pegloticase, a drug for uncontrolled gout, combined with methotrexate (MTX). This Phase 3 trial compares pegloticase given as an 18 mg injection under the skin every two weeks with pegloticase given as an 8 mg intravenous (IV) infusion every two weeks, both alongside weekly oral MTX. The main goal is to see which method better maintains normalized serum uric acid levels below 6 mg/dL for at least 80% of the time during the sixth month of treatment. Participants will be randomly assigned to receive pegloticase either by subcutaneous injection or intravenous infusion every two weeks, along with weekly oral doses of methotrexate. Both groups will be treated over several months while closely monitored. The study is double-blind, meaning neither participants nor researchers know which treatment is being given to maintain unbiased results. During the trial, participants will undergo regular assessments to monitor their serum uric acid levels and overall response to treatment, especially focusing on weeks 20 through 24 (Month 6). Safety and efficacy will be tracked throughout the study, including how well participants tolerate the treatments and any side effects. The study's main measure is the proportion of participants who achieve a sustained uric acid response during Month 6.

Researchers are evaluating whether the drugs retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who are at high risk. This Phase 3 trial enrolls about 4,500 adults with MASLD identified by non-invasive tests indicating an increased likelihood of developing serious liver problems. The study aims to understand how these treatments might affect liver health over time compared to a placebo. Participants will be randomly assigned to receive either retatrutide, tirzepatide, or a placebo, all given by subcutaneous injection. The study will last approximately 224 weeks, during which participants may attend 25 to 30 clinic visits for monitoring and assessment. After the main study, eligible participants can join an optional 2-year extension where all will receive either retatrutide or tirzepatide regardless of their original group. Throughout the trial, participants’ liver function and disease progression will be closely monitored through various health assessments. Researchers will track the time to the first major adverse liver event as the main outcome. Safety and health status will be evaluated regularly during clinic visits, ensuring thorough observation over the long study period.

Researchers are evaluating multiple independent pain treatments under a master protocol designed for chronic pain conditions including osteoarthritis of the knee, chronic low back pain, and diabetic peripheral neuropathic pain. This phase 2 study aims to compare different interventions through disease-state addenda and intervention-specific appendices to better understand their effects on chronic pain. Participants may receive various investigational drugs administered either orally or intravenously, including LY3016859 (IV), LY3556050 (oral), LY3526318 (oral), LY3857210 (oral), or placebo versions given orally or intravenously. Each intervention-specific appendix may begin independently as treatments become available for clinical testing, following the master protocol structure. During the study, participants will be monitored for pain levels using specific scales and assessments related to their condition. Researchers will track the number of participants assigned to each intervention from baseline through week 8. Participants must maintain consistent non-drug pain therapies and discontinue chronic pain medications except for rescue medication during the study. Safety assessments, including physical exams and laboratory tests, will be conducted to ensure participant well-being throughout the trial.

Researchers are conducting a Phase 2, multicenter platform study to evaluate the safety and effectiveness of several investigational treatments for adults with moderately to severely active Inflammatory Bowel Disease (IBD), including Crohn's Disease and Ulcerative Colitis. The study focuses on assessing multiple experimental oral or injectable therapies to better understand their effects on these conditions. Participants will receive one of the study drugs, MT-501 or MT-201, as part of this evaluation. The study aims to gather data on how these treatments perform in terms of safety, how the body processes them (pharmacokinetics), and their biological effects (pharmacodynamics). Treatment effects will be measured over a period of up to 13 weeks. During the study, participants will be monitored for any side effects, serious adverse events, and laboratory test changes. Researchers will also assess the participants' clinical remission status and improvements seen through endoscopic evaluations at 12 to 13 weeks. The total involvement duration includes screening and treatment periods, with careful tracking of outcomes and safety throughout.

Researchers are evaluating the safety and effectiveness of belzupacap sarotalocan (bel-sar) compared to a sham control in patients with primary indeterminate lesions or small choroidal melanoma. This is a Phase 3 randomized, masked, controlled trial aiming to provide clear evidence on bel-sar's use in these eye conditions. The study focuses on patients without metastatic disease who have not previously been treated for their lesions, except possibly with photodynamic therapy. Participants receive bel-sar through a suprachoroidal injection using a specialized microinjector, followed by activation with an infrared laser. The control group undergoes similar procedures with sham devices and sham laser application to maintain masking. The trial is carefully designed to keep patients, assessors, and sponsors unaware of the treatment assignments to ensure unbiased results. Throughout the study, researchers will monitor the time it takes for tumors to progress, up to 65 weeks. Participants will undergo imaging and clinical evaluations to track safety and tumor status. The trial's structured follow-up includes assessments for any adverse effects and effectiveness of the treatment, helping to determine bel-sar's role in managing these eye tumors.

Researchers are conducting a Phase 3 study to evaluate the safety and effectiveness of an intravitreal injection called KSI-101 in adults with macular edema caused by inflammation, known as MESI. This condition involves swelling in the central part of the retina and can affect vision. The study aims to compare KSI-101 to sham injections to understand its impact on improving vision. Participants will receive either KSI-101 or sham injections directly into the eye. The treatment is given through intravitreal injections, which deliver medication inside the eye. The study is randomized, double-masked, and sham-controlled, meaning neither participants nor doctors know who receives the active drug or sham injections. This design helps provide clear and unbiased results. Throughout the study, participants will have their vision assessed, including measuring changes in best-corrected visual acuity (BCVA) at 24 weeks. Researchers will monitor the thickness of the central retina area and check for safety and side effects. Participants will be followed regularly to track vision changes and eye health during the study period.
