Researchers are evaluating zolbetuximab combined with pembrolizumab and chemotherapy in adults with locally advanced, unresectable, or metastatic stomach or gastroesophageal junction (GEJ) cancer. This study focuses on cancer cells that are HER2-negative but positive for the Claudin 18.2 protein and PD-L1, exploring how well zolbetuximab helps the immune system attack the tumor alongside immunotherapy and chemotherapy. The trial is a phase 3, randomized, double-blind study designed to compare the overall survival of participants receiving zolbetuximab with pembrolizumab and chemotherapy versus those receiving a placebo with pembrolizumab and chemotherapy. Participants receive study treatment in 6-week cycles, with zolbetuximab or placebo given by infusion every 2 or 3 weeks. Chemotherapy regimens include either CAPOX (capecitabine tablets and oxaliplatin infusion) or mFOLFOX6 (infusions of 5-fluorouracil, folinic acid, and oxaliplatin) administered on schedules matching the cycles. Pembrolizumab is infused every 3 or 6 weeks. Treatment continues until cancer worsens, is not tolerated, or another therapy is needed, with pembrolizumab given for up to 2 years. After initial cycles, some chemotherapy drugs are adjusted to only include oral capecitabine or certain infusions. During the study, participants visit the clinic for treatments, health checks, and scans to monitor cancer changes and side effects. Researchers also track medical problems related to the treatments and may collect tumor samples if cancer worsens. After stopping treatment, participants have follow-up visits and scans every 9 to 12 weeks, along with telephone check-ins every 3 months. The primary outcome measured is overall survival up to 72 months, with ongoing monitoring to evaluate safety and treatment effects.

Researchers are evaluating the effects of felzartamab in adults with Immunoglobulin A nephropathy (IgAN), a kidney disease caused by the buildup of abnormal IgA antibodies in the kidneys. This buildup leads to inflammation and damage, causing protein to appear in the urine. The study aims to understand how felzartamab influences proteinuria and kidney function, while also assessing the safety and how the body processes this treatment. This is a Phase 3, randomized, double-blind, placebo-controlled study focusing on adults with IgAN. Participants will be randomly assigned to receive either felzartamab or a placebo through intravenous (IV) infusions. Neither the participants nor the researchers will know which treatment is given. The treatment period lasts 24 weeks followed by an 80-week follow-up period. In total, participants will attend 17 study visits over about 2 years to receive infusions and participate in study activities. During the study, participants will undergo assessments including urine tests to measure protein levels, kidney function evaluations, and safety monitoring. Researchers will track changes in proteinuria from the start of the study to Week 36 as the main outcome. Additional measurements will include kidney function, clinical endpoints, and the study of how felzartamab is processed by the body. Participant safety and long-term effects will be monitored throughout the study and follow-up periods.
