Researchers are investigating the targets of disease-reactive T cells in patients with various autoimmune diseases, including inflammatory bowel diseases, celiac disease, ankylosing spondylitis, multiple sclerosis, scleroderma, systemic sclerosis with lung involvement, and others. The study focuses on identifying the natural peptide targets recognized by T cell receptors (TCRs) in inflamed tissues, which may help develop new treatments that specifically target these immune responses. This approach uses high-throughput technology developed by TScan to discover these targets from active disease tissues. Participants will provide tissue samples during clinically indicated procedures or research biopsies, along with companion blood samples collected around the same time. The study involves isolating T cells from diseased tissues and matched blood or normal tissues, then identifying T cell clones expanded in the affected organs. These clones' TCR targets will be determined using TScan's genome-wide technology. No specific drug treatments are administered by the study; instead, it collects biospecimens for analysis. During the study, researchers will collect and analyze tissue and blood samples to identify disease-associated TCRs and their peptide targets over a 3-year period. Participants must be willing and able to consent and undergo the procedures. The study tracks T cell targets as the primary outcome, aiming to discover new therapeutic targets. Safety considerations include excluding those with conditions that increase biopsy risks. Total participation duration depends on the timing of tissue collection and subsequent analyses.

Researchers are studying a new treatment for HIV-1 infection that combines two medicines, islatravir and ulonivirine, taken once weekly. The goal is to see if this new study treatment works as well as the standard antiretroviral therapy (ART), which usually involves taking up to three medicines once or twice daily. This research also aims to learn about the safety and tolerability of the study treatment compared to the standard ART. The study compares the once-weekly combination of islatravir and ulonivirine with the standard daily treatment of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). Participants will take either the study drugs or the standard drugs for 96 weeks. Some participants may receive matching placebos as part of the study design. The treatment is given orally as capsules or tablets according to the assigned group. Participants will be monitored throughout the study with regular assessments, including measuring the amount of HIV-1 virus in the blood to see if it is suppressed below 50 copies/mL at weeks 24 and 48. The study will also track any side effects or adverse events and whether participants stop the treatment due to these events. Overall, the study lasts about 96 weeks, with ongoing safety and effectiveness evaluations to understand how well the treatments work and how safe they are over time.

Researchers are looking for new medicines to prevent HIV-1 (Human Immunodeficiency Virus Type 1) infection. The goals of this study are to learn: * If taking MK-8527 once a month works to prevent HIV-1 infection as well as or better than a standard (usual) pre-exposure prophylaxis (PrEP) taken once a day * About the safety of MK-8527 and if people tolerate it

Researchers are evaluating the effectiveness, safety, and tolerability of subcutaneous ianalumab in adults with diffuse cutaneous systemic sclerosis. This Phase 2 study compares ianalumab with a placebo in participants diagnosed according to established classification criteria, focusing on those with active disease and specific autoantibodies. The goal is to better understand ianalumab's impact on this condition over a long treatment period. The study includes several phases: up to 6 weeks for screening, followed by a 52-week initial treatment period where participants receive either ianalumab or placebo by subcutaneous injection. After this, there is a second 52-week open-label treatment period where all participants receive ianalumab. Finally, a post-treatment follow-up period lasts at least 20 weeks and can extend up to 2 years after the last dose. Participants will undergo various assessments throughout the study, including evaluations of their skin condition using the rCRISS25 response at week 52. Safety and tolerability will also be closely monitored. The study involves regular visits for clinical evaluations, laboratory tests, and monitoring of disease activity and antibody status, with the total participation potentially lasting over two years including follow-up.

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 intravitreal EYE103 in participants with neovascular age-related macular degeneration (NVAMD) or macular edema following branch retinal vein occlusion (BRVO). This Phase 2, randomized, dose-masked study includes four patient cohorts: treatment-naive NVAMD participants, incomplete responder (IR) NVAMD participants as monotherapy, IR NVAMD participants receiving EYE103 combined with aflibercept 2.0 mg, and treatment-naive BRVO participants. The study aims to assess safety and efficacy of different doses of EYE103 in these conditions. Participants in each cohort will be randomly assigned to receive either a low or high dose of EYE103 via intravitreal injection. All participants will receive three injections spaced four weeks apart. IR NVAMD participants in the combination therapy cohort will also receive an injection of aflibercept 2.0 mg on Day 1. The timing of enrollment into each cohort is determined by the Sponsor. Participants will undergo safety and efficacy assessments at each injection visit, with some cohorts returning two weeks after injections for further evaluations. Assessments include measuring best-corrected visual acuity using the ETDRS chart, slit-lamp biomicroscopy, fundoscopy, and spectral domain optical coherence tomography (SD-OCT) to measure central subfield thickness. The study concludes at Week 12, which is the end-of-study visit for all participants.

Researchers are evaluating the effects, safety, and response to the medicine zasocitinib in children and teenagers aged 4 to under 18 years who have moderate-to-severe plaque psoriasis. The study is designed in two parts, with Part A including both children and teenagers and Part B including only children. Initially, only teenagers meeting the study criteria can join, with children joining later after more data is collected from other studies. In Part A, participants are randomly assigned to receive either zasocitinib or a placebo for the first 16 weeks, after which all receive zasocitinib for the rest of the study. Participants in Part B receive zasocitinib throughout. The treatment period lasts up to 208 weeks, followed by a 4-week safety follow-up. Both drug and matching placebo are used, and the study is conducted at multiple centers. Participants will attend multiple visits to the study site over a total duration of up to 4 years and 2 months, including a screening period of up to 35 days. Researchers will assess improvements in psoriasis severity using measures like the Static Physician's Global Assessment and Psoriasis Area and Severity Index at week 16. In Part B, they will also study how the body absorbs and processes zasocitinib by measuring drug levels at specific times. Safety and tolerability will be monitored throughout the study.

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 the effectiveness, safety, tolerability, and pharmacodynamics of multiple doses of APL-3007 combined with Syfovre/Pegcetacoplan (APL-2) in patients aged 60 years and older diagnosed with geographic atrophy secondary to age-related macular degeneration. This Phase 2, randomized, placebo-controlled, multicenter, masked study focuses on measuring changes in retinal pigment epithelium lesions using advanced artificial intelligence-based SD-OCT imaging. Participants will receive either the combination of APL-3007 with pegcetacoplan (APL-2) or a placebo. The study includes a treatment period with multiple doses administered, aiming to assess the impact on geographic atrophy lesions over a 12-month period. Syfovre injections at 6-8 week intervals prior to enrollment are part of the inclusion criteria. During the study, participants will undergo various eye imaging assessments such as OCT and FAF to monitor lesion size and progression. Researchers will evaluate changes in lesions at month 12 compared to baseline. Safety and tolerability will be closely monitored through laboratory tests, clinical evaluations, and vaccination status requirements. The study duration includes regular visits for treatment administration and monitoring over at least one year.

This clinical study is testing a new medication, VH4524184, to see if it can effectively treat HIV-1 in adults who have never received treatment for their infection. The study is comparing two different doses of VH4524184, each taken with the medications emtricitabine and tenofovir alafenamide (FTC/TAF), to a standard HIV treatment called dolutegravir and lamivudine (DTG/3TC). The purpose of the study is to provide data on the long-term antiviral activity of the VH4524184 and provide information regarding dosing formulation for further evaluations.
