Researchers are evaluating a new treatment called ifinatamab deruxtecan (I-DXd) for men with metastatic castration-resistant prostate cancer (mCRPC). This study compares I-DXd to chemotherapy to see if it helps people live longer overall and live longer without their cancer worsening. It is a Phase 3, open-label trial focused on patients who have progressed on prior therapies and have evidence of metastatic disease. Participants receive either I-DXd through an intravenous infusion every 3 weeks or docetaxel chemotherapy administered every 3 weeks. Prednisone tablets are also given daily as part of the treatment plan. Before each I-DXd dose, premedication is provided to help prevent nausea and vomiting using a combination of drugs such as corticosteroids and anti-nausea medicines. Treatment continues until disease progression, unacceptable side effects, or other reasons to stop. During the study, researchers monitor overall survival and how long patients live without their cancer progressing, for up to about 36 months. Participants undergo tumor tissue collection, scans, and assessments to track disease status and side effects. Safety is closely watched throughout treatment. The study includes men aged 18 and older with confirmed prostate cancer and metastatic disease who have previously received certain hormone therapies but no prior taxane chemotherapy for mCRPC.

Researchers are studying children with Hypochondroplasia, a genetic condition affecting growth, to observe how their growth changes over time and to understand the clinical course of this condition. The study gathers detailed growth measurements and other important health variables to track development. This is an observational study conducted across multiple centers and countries, focusing on children up to 15 years old with confirmed genetic diagnosis of Hypochondroplasia. The study does not involve active treatments but monitors participants regularly over a long period, up to 15 years. Every six months, various growth measurements are taken, including annualized growth velocity, height, body mass index (BMI), and ratios of different body segments such as upper to lower body, leg length ratios, and arm span to height. These detailed assessments help track changes in physical growth and body proportions over time. Participants will attend scheduled visits every six months for up to 15 years, during which researchers will measure and record growth parameters and body ratios. The study aims to capture changes in growth patterns and body measurements continuously throughout the study period. No specific interventions are given, but the study carefully monitors participant growth and development to better understand Hypochondroplasia and its effects on children.

Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study to see if it can reduce the risk of major adverse cardiovascular events (MACE-PLUS) in adults with established atherosclerotic cardiovascular disease (ASCVD) or those at high risk for a first ASCVD event. The study compares AZD0780 to a placebo and monitors participants from randomization until the primary analysis censoring date, followed by a final study closure visit. Participants will be randomly assigned to receive either oral AZD0780 or an oral placebo once daily. The treatment period lasts until the primary analysis censoring date, after which a study closure visit will occur. The study is event-driven and designed to assess the time to the first major cardiovascular event during treatment. During the study, participants will be closely monitored with various assessments to evaluate cardiovascular outcomes and safety over approximately 54 months. Researchers will track the time to first event of any component of MACE-PLUS and collect data to assess the effect of AZD0780 compared to placebo. The study includes regular visits and evaluations to ensure participant safety and adherence to treatment.

Researchers are evaluating the drug disitamab vedotin, alone or combined with pembrolizumab, to treat urothelial cancer that expresses HER2. This cancer is locally advanced, cannot be removed by surgery, or has spread to other parts of the body. The study aims to see how well the drug works and how safe it is for participants by monitoring side effects and treatment responses. Participants will receive disitamab vedotin through an intravenous (IV) infusion every two weeks. Pembrolizumab, when given, is administered by IV on the first day of each six-week cycle. The study includes several groups, called cohorts, each with different treatment histories and eligibility criteria. Treatment and evaluation may continue for about two years. During the study, participants will have regular tests including scans to measure tumor response, lab tests, heart function checks, and monitoring for adverse events. Researchers will also track drug levels in the blood and any changes in heart function. The study will assess confirmed tumor responses and safety outcomes over approximately two years, with close monitoring to understand how participants respond to the treatments and any side effects experienced.

Researchers are evaluating the safety and effectiveness of ifinatamab deruxtecan (I-DXd) combined with the immune checkpoint inhibitor atezolizumab, with or without carboplatin, in adults with extensive stage-small cell lung cancer (ES-SCLC). This study includes two parts: Part A, a Phase 1b safety run-in phase, and Part B, a Phase 2 dose optimization phase. The main goal is to assess treatment-related side effects and determine the best dose of I-DXd in these combination therapies for first-line treatment. The study has two cohorts: Cohort 1 includes participants receiving I-DXd as maintenance therapy after initial induction treatment with carboplatin, etoposide, and atezolizumab; Cohort 2 includes participants receiving I-DXd during both induction and maintenance phases without prior ES-SCLC treatment. All study drugs, including I-DXd, atezolizumab, and carboplatin, are given intravenously. Participants will receive treatments in cycles of 21 days, with specific dosing and combination regimens evaluated during the study. Participants will undergo regular assessments including monitoring for dose-limiting toxicities and any treatment-emergent adverse events from the start of treatment up to 37 months. Safety evaluations, laboratory tests, imaging, and other study procedures will be conducted according to the protocol. The study aims to closely observe how participants tolerate the treatments and to collect important data on side effects and overall safety throughout the study period.

Researchers are evaluating the effectiveness and safety of nipocalimab compared to placebo in adults with generalized myasthenia gravis (gMG), a condition causing muscle weakness. This phase 3, multicenter, randomized, double-blind study also includes a subcutaneous substudy to assess how nipocalimab works in the body when given as an injection under the skin compared to intravenous infusion. Participants will receive nipocalimab or a matching placebo through intravenous infusion. In the subcutaneous substudy, nipocalimab will be administered under the skin. The study includes groups receiving different forms of the drug, with dosing schedules detailed in the protocol. The subcutaneous substudy requires participants to maintain stable doses of corticosteroids and/or immunosuppressants for the first 8 weeks. During the study, participants will undergo assessments including the Myasthenia Gravis - Activities of Daily Living (MG-ADL) score measured at baseline and weeks 22 to 24. Blood samples will be collected to measure antibody levels and total IgG from before the first dose up to week 8 in the sub-study. Safety and efficacy will be closely monitored throughout the trial period.

This research aims to evaluate the efficacy and safety of telitacicept in treating generalized myasthenia gravis (gMG), an autoimmune disease where autoantibodies disrupt nerve-to-muscle communication, causing muscle weakness that worsens with activity. The study addresses the challenge of limited effective therapies for this condition. Telitacicept is a fully human fusion protein designed to block specific immune system signals that promote B-cell growth and maturation, potentially reducing autoimmune symptoms in gMG. The study is a Phase 3, randomized, double-blind, placebo-controlled trial with an open-label extension. Participants will receive subcutaneous injections of either telitacicept or placebo. The study includes a 4-week screening period, a 24-week double-blind treatment phase, a 48-week open-label extension, followed by a variable-duration extended open-label extension until telitacicept is approved or development ends, and an 8-week end-of-study follow-up. Participants will undergo assessments including the Myasthenia Gravis-Activities of Daily Living (MG-ADL) score to measure changes in daily functioning by Week 24. The study also monitors safety and efficacy over the treatment and extension periods. Throughout the trial, various clinical evaluations will be conducted to track disease status and response to treatment, ensuring comprehensive monitoring of participant health and outcomes.

Researchers are evaluating the efficacy and safety of belimumab compared to a placebo, alongside standard therapy, for adults with systemic sclerosis associated interstitial lung disease (SSc-ILD). This Phase 2/3 randomized, double-blind study aims to assess how belimumab affects lung function and other disease symptoms such as skin thickening and fatigue, which impact quality of life. Participants will receive either belimumab or placebo administered subcutaneously. The study focuses on those diagnosed with diffuse cutaneous systemic sclerosis and active or progressive disease. Treatment is given under blinded conditions, and participants must be capable of self-administering the medication or have a caregiver to assist. During the study, lung function will be monitored by measuring changes in forced vital capacity (FVC) from baseline to Week 52. Researchers will also assess skin involvement and general symptoms. Safety and tolerability will be closely followed throughout the trial, which includes screening and regular assessments to evaluate treatment effects and participant well-being.

Researchers are studying the effects of DMX-200 (repagermanium), a drug that blocks a receptor involved in inflammation, in people with focal segmental glomerulosclerosis (FSGS) who are also taking an angiotensin II receptor blocker (ARB). This Phase 3 trial aims to assess the safety and effectiveness of DMX-200 compared to placebo over 104 weeks in adults and adolescents aged 12 to 17 years. Following the initial study, an open-label extension will evaluate long-term safety and benefits for up to two more years. Participants will be randomly assigned to receive either DMX-200 at 120 mg twice daily or a placebo, while continuing their ARB treatment. The study includes a screening and qualification period lasting 6 to 14 weeks, a 104-week double-blind treatment phase, and a 4-week follow-up after treatment. Those completing this phase may enter the open-label extension for an additional minimum of 104 weeks, with another 4-week follow-up period, making the total study duration about 230 weeks. During the trial, participants will undergo regular assessments including urine protein and creatinine testing, kidney function monitoring by estimated glomerular filtration rate (eGFR), and safety evaluations. The main outcomes measured are changes in proteinuria, kidney function slope up to week 104, and long-term safety through week 216. Safety will be closely monitored throughout both the double-blind and extension periods to understand the drug's effects over time.

Researchers are evaluating the safety and effectiveness of a new oral medicine called vepugratinib compared with a placebo in adults with advanced or metastatic urothelial carcinoma, a type of bladder cancer that has a specific FGFR3 genetic alteration. This Phase 3 study aims to see if vepugratinib combined with two other drugs, enfortumab vedotin (EV) and pembrolizumab, can improve treatment outcomes for people who have not received prior systemic therapy for their cancer. Participants will receive either vepugratinib or placebo taken orally alongside enfortumab vedotin and pembrolizumab, both administered by intravenous infusion. The study is randomized, double-blind, and placebo-controlled to ensure reliable comparison between the vepugratinib and placebo groups. Treatment and monitoring will continue for up to approximately 6 years, allowing long-term assessment of safety and treatment effects. During the study, participants will be regularly evaluated for treatment-related side effects, response rates, and how long the cancer remains controlled without progression. Researchers will use established criteria to measure tumor response and will conduct thorough safety monitoring over the entire study period. Participation may last up to six years, during which participants will undergo laboratory tests, imaging, and clinical assessments to track their health and treatment response.
