Researchers are investigating the specific targets of T cells involved in autoimmune diseases by studying tissues from patients with active organ inflammation caused by autoimmune conditions. The study aims to identify which T cells are activated and expanding in diseased tissues compared to blood or normal tissues. This information will help discover new peptide targets and their associated T cell receptors TCRs to develop potential new therapies for autoimmune diseases. Participants will provide tissue samples and matched blood samples during clinical procedures such as endoscopy, arthrocentesis, lumbar puncture, skin biopsy, bronchoscopy, or surgery, depending on their autoimmune condition. The study includes several groups covering diseases like Crohns disease, ulcerative colitis, celiac disease, ankylosing spondylitis, multiple sclerosis, scleroderma, systemic sclerosis, and other autoimmune diseases. Samples may come from excess clinical materials or research-specific biopsies, with the possibility of serial sampling over time. During the study, participants will undergo standard clinical procedures with collection of additional tissue or fluid samples and companion blood draws. Researchers will analyze these samples to identify peptide targets linked to disease-reactive T cells over a period of up to three years. The study includes comprehensive assessments of tissues and blood to understand T cell activity in autoimmune disorders, with monitoring of participant safety and no interventions beyond routine clinical care.

Researchers are evaluating new treatment options for people living with HIV-1 Human Immunodeficiency Virus Type 1 who have not been treated before. The current standard treatment, antiretroviral therapy ART, involves taking multiple medicines daily and may cause other health problems. This study aims to compare a new study ART combining two medicines, islatravir and ulonivirine, taken once a week, against the standard daily ART to see if it works as well and is safe and tolerable. Participants will receive one of several treatments for 96 weeks the study ART with islatravir and ulonivirine taken once weekly, the standard ART with bictegraviremtricitabinetenofovir alafenamide BICFTCTAF taken once daily, or combinations involving placebos matching these treatments. The study includes two phases Phase 2 which is open-label, and Phase 3 which is double-blind and randomized. During the study, participants will have regular assessments including measuring the amount of HIV-1 RNA in their blood and monitoring for adverse events and medication tolerance. Researchers will evaluate how well the treatments control the virus and affect immune cells over 24, 48, and 96 weeks. Safety monitoring will continue for about 102 weeks. The total study duration for participants is up to 96 weeks of treatment plus follow-up.

Researchers are evaluating new medicines to prevent HIV-1 Human Immunodeficiency Virus Type 1 infection. This Phase 3 clinical study aims to determine if taking the drug MK-8527 once a month can prevent HIV-1 infection as well as or better than the standard daily pre-exposure prophylaxis PrEP. The study also assesses the safety and tolerance of MK-8527 in participants. Participants are randomly assigned to one of two groups. One group receives 11 mg of MK-8527 once monthly along with a daily placebo pill matching FTCTDF. The other group receives a daily dose of FTC245 mg TDF and a monthly placebo matching MK-8527. This treatment period lasts for approximately two years, followed by an additional 28-day period where all participants receive open-label FTCTDF daily. During the study, participants will undergo regular monitoring to check for HIV-1 infection and any adverse events. Researchers will track the number of participants who acquire HIV-1, experience side effects, or stop treatment due to side effects over the two-year period. Safety and adherence assessments will be conducted to evaluate the study treatments. The total participation time includes the two-year treatment phase plus the 28-day follow-up with open-label FTCTDF.

Researchers are evaluating the efficacy, safety, and tolerability of subcutaneous ianalumab in adults with diffuse cutaneous systemic sclerosis, a condition characterized by skin thickening and other systemic symptoms. This Phase 2 study compares ianalumab to a placebo to understand its impact on this disease, aiming to provide new treatment options for affected individuals. The study is sponsored by Novartis Pharmaceuticals and employs a randomized, double-blind design to ensure reliable results. Participants receive either ianalumab or placebo through subcutaneous injections during the initial 52-week treatment period. After this, all participants enter a second 52-week open-label phase where they receive ianalumab. Following treatment, there is a post-treatment follow-up lasting at least 20 weeks and up to 2 years to monitor long-term effects. The study includes a screening period lasting up to 6 weeks before treatment begins. Throughout the study, participants undergo regular assessments including measuring response based on the rCRISS25 scale at Week 52, lung function tests, skin scoring, and disability index evaluations. Blood samples are taken periodically to measure drug levels and antibodies. Safety is closely monitored through adverse event reporting up to Week 208. The total participation time can extend over several years including treatment and follow-up phases.

Researchers are evaluating the effects of enicepatide, a dual GLP-1GIP receptor agonist, at multiple doses compared with placebo for weight management in adults with obesity or overweight who do not have Type 2 diabetes. This Phase III, randomized, double-blind study aims to assess both the efficacy and safety of once-weekly enicepatide in this population, addressing weight-related comorbidities such as prediabetes, hypertension, and cardiovascular conditions. Participants will be randomly assigned to receive either placebo or one of three enicepatide dosing regimens, administered once weekly via an integrated drug-device combination product. The treatment phase lasts through 72 weeks, during which changes in body weight and other health measures are monitored. The study includes multiple assessments to track body weight percentage change, waist circumference, fasting glucose and insulin levels, lipid profiles, blood pressure, and quality of life measures. Throughout the study, participants will undergo regular evaluations including physical examinations, laboratory tests, and questionnaires related to physical functioning and urinary incontinence. Researchers will monitor adverse events, patient-reported health questionnaires, and biomarkers at baseline and weekly intervals through week 72. This long-term follow-up allows for a comprehensive assessment of treatment effects and safety in participants managing obesity or overweight without Type 2 diabetes.

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 investigating new treatments for neovascular age-related macular degeneration NVAMD, a condition that affects vision. This study aims to learn if a medicine called tiespectus also known as MK-8748 or EYE201 can treat NVAMD as well as the standard treatment called aflibercept. The trial is a pivotal Phase 23 study that compares these treatments in people newly diagnosed with NVAMD. Participants are randomly assigned to one of three groups one group receives a low dose of tiespectus, another receives a high dose of tiespectus, and the third group receives aflibercept. Those in the tiespectus groups get three initial injections every 4 weeks, then continue injections every 8 weeks until week 48, followed by treatments at intervals based on their individual response up to week 92. The aflibercept group receives three initial injections followed by injections every 8 weeks until week 92. During the study, participants are regularly assessed for changes in their best-corrected visual acuity using ETDRS letters from baseline to one year. Other evaluations include eye imaging to measure retinal thickness and monitoring for any adverse events up to approximately 96 weeks. The study lasts over one year with ongoing visits to track treatment response and safety.

This research investigates intravitreal EYE103 in adults with neovascular age-related macular degeneration NVAMD or macular edema caused by branch retinal vein occlusion BRVO. The trial is randomized and dose-masked, including four different patient groups to study different doses and combinations of EYE103, aiming to assess its effects in these eye conditions. Participants are divided into four cohorts treatment-naive NVAMD, incomplete responders IR with NVAMD as monotherapy, IR NVAMD combined with aflibercept, and treatment-naive BRVO. Each cohort randomly receives either a low or high dose of EYE103 via intravitreal injection. All receive three injections spaced 4 weeks apart the IR NVAMD combination group also receives aflibercept on Day 1. Assessments occur at each injection visit and some groups return 2 weeks post-injection for extra evaluations. During the 12-week study, participants undergo safety and efficacy assessments including vision tests using ETDRS charts, slit-lamp exams, fundoscopy, and imaging with spectral domain optical coherence tomography SD-OCT to measure retinal thickness. The studys main measure is the change in best-corrected visual acuity at Week 12. The trial also monitors retinal thickness and vision changes throughout. The Week 12 visit marks the studys end for all participants.

Researchers are studying how well the medicine zasocitinib works, how safe it is, and how children and teenagers aged 4 to under 18 with moderate-to-severe plaque psoriasis respond to it. The study is divided into two parts Part A includes both children and teenagers, while Part B includes only children. Initially, only teenagers who meet the study requirements can participate, with children joining after sufficient information is collected from other studies. Participants in Part A will be randomly assigned to receive either zasocitinib or a matching placebo daily for the first 16 weeks, followed by open-label zasocitinib treatment until the study ends. In Part B, all children will receive zasocitinib throughout the study. The treatment doses for children will be based on their weight, and adolescents will receive a fixed dose. The study lasts up to 4 years and 2 months, including screening, treatment, and safety follow-up periods. During the study, participants will visit the study site multiple times for assessments. Researchers will measure improvements in skin condition using tools like the Static Physicians Global Assessment and Psoriasis Area and Severity Index at Week 16 and throughout the open-label period. Safety and drug levels in the body will also be monitored. After treatment, there is a 4-week safety follow-up. Overall, participants will be involved for up to 217 weeks, including screening, treatment, and follow-up.

Researchers are evaluating whether retatrutide and tirzepatide can prevent major adverse liver outcomes in adults with metabolic dysfunction-associated steatotic liver disease MASLD who are at high risk based on non-invasive tests. This Phase 3 randomized controlled trial aims to assess these treatments compared to placebo in about 4,500 adults over approximately 224 weeks. The study is sponsored by Eli Lilly and Company and focuses on liver disease progression and related health measures. Participants will be randomly assigned to receive retatrutide, tirzepatide, or placebo, all administered by subcutaneous injection. The trial includes two placebo groups corresponding to each experimental drug. After completing the main study, eligible participants may join a 2-year extension where all will receive either retatrutide or tirzepatide regardless of their initial assignment. During the study, participants may attend around 25 to 30 clinic visits for health monitoring, study procedures, and assessments of liver function and disease status. Researchers will measure the time to major adverse liver outcomes, changes in liver fibrosis scores, liver stiffness, liver fat content, liver enzyme levels, body weight, and cardiovascular events. Monitoring will continue from baseline through study completion, with detailed evaluations at multiple timepoints including week 104.
