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 the efficacy and safety of trontinemab in people with early symptomatic Alzheimers disease, ranging from mild cognitive impairment to mild dementia due to Alzheimers. This Phase III trial aims to understand how trontinemab affects cognitive decline and disease progression in this population. Participants are randomly assigned to receive either intravenous trontinemab or a placebo in a parallel-group design. Treatment is administered by IV infusion, and the effects are compared over a period of 72 weeks. The study includes comprehensive safety and efficacy assessments throughout this period. During the 72 weeks of the study, participants will undergo various evaluations including cognitive tests such as the Clinical Dementia Rating-Sum of Boxes CDR-SB, Alzheimers Disease Assessment Scales, brain imaging with PET and MRI scans, and biomarker measurements in cerebrospinal fluid and blood. Safety monitoring includes tracking adverse events, infusion reactions, and antibody development. The study requires participants to have a study partner and to complete all study procedures over this time.

Researchers are evaluating the effectiveness of pegloticase administered by two different methodssubcutaneous under the skin injection versus intravenous into a vein infusioneach combined with methotrexate MTX in participants who have uncontrolled gout. The main goal is to compare how well these two treatment methods maintain normal serum uric acid levels over a six-month period. This Phase 3 trial is designed as a double-blind, randomized controlled study to provide reliable information on treatment responses.

Researchers are evaluating the safety and effectiveness of three different dose regimens of MORF-057, a small molecule drug, in adults with moderately to severely active Crohns disease CD. This Phase 2, randomized, double-blind, placebo-controlled, multicenter study aims to compare these doses with a matching placebo during an induction treatment period. The study includes adult participants who have active symptoms of CD and have not adequately responded to other treatments. Participants will first undergo a 14-week induction period where they receive either one of the three blinded MORF-057 dose regimens or a matching placebo, all taken orally. Following this, all participants enter a 38-week maintenance period receiving open-label MORF-057. Those who complete this 52-week treatment phase may have the chance to continue treatment for an additional 52 weeks during a long-term extension. MORF-057 is designed to selectively inhibit integrin 47. During the study, participants will have their disease activity monitored using endoscopic assessments and clinical symptom scores, such as the Simple Endoscopic Score for Crohns Disease SES-CD and the Crohns Disease Activity Index CDAI. Researchers will assess the proportion of participants showing endoscopic response and clinical remission at Week 14. Safety and adherence will be closely followed throughout the treatment and extension phases. The entire study spans up to 6 years, allowing for long-term evaluation.

Researchers are evaluating changes in bone mineral density in premenopausal women with heavy menstrual bleeding caused by uterine fibroids or moderate-to-severe pain from endometriosis. This Phase 3B, open-label study looks at the effects of continuous treatment with a relugolix combination tablet for up to 48 months 4 years, followed by a 1-year period to monitor bone health after stopping treatment. Participants will take a daily oral relugolix combination tablet containing relugolix 40 mg, estradiol 1 mg, and norethindrone acetate 0.5 mg for 4 years. Bone mineral density will be measured every 6 months using dual-energy X-ray absorptiometry DXA. Some women who have completed a previous related study may join to complete 3 years of treatment. After treatment ends, bone density will be checked again at 6 months and 12 months during the follow-up year. Women in the study will have regular visits for bone density scans and health assessments, including physical and gynecological exams, lab tests, and vital signs. Researchers will track changes in bone density at the spine, hip, and femoral neck throughout treatment and follow-up. They will also monitor for any fractures or adverse events during the 4 years of treatment and the 1-year post-treatment period. Total participation can last up to 5 years including the follow-up.

Researchers are evaluating efruxifermin EFX in a phase 3, randomized, double-blind, placebo-controlled study involving adults with compensated cirrhosis caused by NASH Nonalcoholic Steatohepatitis or MASH Metabolic Dysfunction-Associated Steatohepatitis. This study aims to assess the safety and effectiveness of EFX in preventing significant clinical events such as disease progression and liver decompensation over a period of up to 5 years. Participants are randomly assigned to receive either efruxifermin 50 mg or a placebo, both given by subcutaneous injection. The study includes two cohorts one with biopsy-proven compensated cirrhosis and specific metabolic scores, and another with biopsy-proven or non-invasive diagnosis of compensated cirrhosis. The study treatment and monitoring extend up to 5 years, with evaluations at 96 weeks and long-term follow-up to track liver fibrosis, markers of liver injury, insulin sensitivity, glycemic control, body weight, and safety outcomes. During the trial, participants undergo regular assessments including laboratory tests, ECGs, ultrasounds, and vital sign monitoring. Researchers will measure changes in liver fibrosis, steatohepatitis resolution, and metabolic markers throughout the study. Safety and tolerability are closely tracked by documenting adverse events and exposure duration. The study duration allows for long-term observation of treatment effects and disease progression, with participant involvement lasting up to 5 years.

Researchers are evaluating efruxifermin EFX in adults with non-cirrhotic nonalcoholic steatohepatitis NASH or metabolic dysfunction-associated steatohepatitis MASH who have liver fibrosis stage 2 or 3. This Phase 3, multi-center, randomized, double-blind, placebo-controlled study aims to assess the safety and efficacy of EFX compared with placebo. The trial includes about 1,650 participants divided into two cohorts based on liver biopsy characteristics and fibrosis stage. Participants will be randomly assigned to one of three groups EFX 28 mg, EFX 50 mg, or placebo, each given as a weekly subcutaneous injection. Cohort 1 will be evaluated over 52 weeks for histologic efficacy endpoints, while Cohort 2 will have assessments over 96 weeks. After these periods, participants may continue long-term treatment and clinical follow-up for up to approximately 240 weeks total. A follow-up visit will occur about 30 days after the last dose. During the study, participants will undergo liver biopsies, blood tests, and non-invasive assessments such as FibroScan and Enhanced Liver Fibrosis ELF score to monitor liver health and fibrosis. Researchers will track liver-related clinical outcomes, including liver events and survival, as well as safety and tolerability of the treatment. Participants who stop the study drug may still continue with scheduled assessments to support long-term safety and efficacy evaluations.

Researchers are evaluating how well guselkumab works compared to risankizumab in adults with moderately to severely active Crohns Disease, a long-term condition causing severe inflammation in the intestinal tract. This Phase 3b study aims to compare the effectiveness and safety of these two drugs for treating this condition. Participants will be randomly assigned to one of two groups. One group will receive guselkumab with induction doses given under the skin at Weeks 0, 4, and 8, followed by maintenance doses every 4 weeks from Week 12 through Week 52. The other group will receive risankizumab with induction doses given intravenously at Weeks 0, 4, and 8, followed by maintenance doses under the skin every 8 weeks from Week 12 through Week 52. During the study, participants will be monitored for up to about three years to assess deep remission at Week 52 and other clinical outcomes such as clinical remission, endoscopic response, steroid-free remission, and safety measures including laboratory tests and adverse events. The study includes ongoing safety monitoring through Week 165 with regular assessments to track disease activity and treatment effects.

Researchers are evaluating the use of Vedolizumab in adults with moderate to severely active Ulcerative Colitis UC or Crohns Disease CD, which are chronic gut conditions causing symptoms such as diarrhea, inflammation, bleeding, and abdominal pain. The study aims to measure how many participants achieve remission, meaning their symptoms disappear, after 14 weeks of treatment. This is a Phase 4 treatment study sponsored by Takeda, focusing on the effectiveness of Vedolizumab administered in a community setting. Participants with either UC or CD will receive Vedolizumab intravenously IV during the first 6 weeks, with doses given at Weeks 0 and 2, and possibly an additional IV dose at Week 6. After this initial period, participants may switch to subcutaneous under the skin injections of Vedolizumab every two weeks from Week 6 until Week 50. If the treatment does not appear effective by Week 14, participants may stop Vedolizumab and switch to another therapy. Additional required visits occur at 26 weeks and 52 weeks, with a final check 18 weeks after the last Vedolizumab dose. Throughout the study, participants will visit the clinic multiple times for treatment and monitoring. Assessments include patient-reported symptom measures at Weeks 6, 14, and 52, clinical response evaluations, and endoscopic examinations to observe mucosal healing. Blood and stool tests will measure inflammation markers like C-reactive protein and fecal calprotectin. Safety monitoring will track serious infections up to 72 weeks. Overall, participants are involved for about one year of treatment plus follow-up to evaluate the long-term effects of Vedolizumab.

Researchers are evaluating the efficacy, safety, and tolerability of IMVT-1402 in adults with Graves disease who remain hyperthyroid despite treatment with antithyroid drugs ATD. The study is a randomized, double-blind, placebo-controlled Phase 2b trial aiming to compare IMVT-1402 against placebo by measuring thyroid hormone levels and ATD dose changes at Week 26. Participants receive either IMVT-1402 or placebo via subcutaneous injections once weekly. Some groups will receive IMVT-1402 for 52 weeks, others IMVT-1402 for 26 weeks followed by placebo for 26 weeks, and one group will receive placebo for 52 weeks. The study evaluates thyroid hormone levels, seronegative status for thyroid receptor antibodies, and sustained euthyroidism at multiple time points up to Week 104. During the trial, participants undergo regular assessments of thyroid hormones T3, FT3, FT4, TSH, antibody levels, and clinical status. Researchers will monitor participants up to two years to assess the proportion achieving normal thyroid function without ATD and maintaining this status over time. Safety and tolerability of IMVT-1402 are also evaluated throughout the study.
