Researchers are evaluating zolbetuximab combined with pembrolizumab and chemotherapy in adults with stomach or gastroesophageal junction GEJ cancer. This study focuses on cancers that do not have the HER2 protein but do express Claudin 18.2. The goal is to understand how well zolbetuximab works with pembrolizumab and chemotherapy compared to a placebo with pembrolizumab and chemotherapy in people with advanced or metastatic disease that cannot be removed by surgery or has spread to other parts of the body. Participants will be randomly assigned to receive either zolbetuximab or a placebo, both given via intravenous infusion every 2 or 3 weeks, alongside pembrolizumab infusions every 3 or 6 weeks. Chemotherapy will be administered using one of two regimens, CAPOX or modified FOLFOX6, over multiple cycles lasting about 42 days each. Treatment continues until the cancer worsens, side effects prevent further use, or another therapy is needed. Pembrolizumab may be given for up to 2 years. During the study, participants will visit the clinic for infusions and health monitoring, including scans to check cancer status. Medical problems and treatment side effects will be recorded. After treatment ends, participants will continue to have regular health checks and scans every 9 to 12 weeks, along with phone check-ins every 3 months. The study will measure overall survival, disease progression, response rates, and safety over several years, with up to 72 months of follow-up for some outcomes.

Researchers are studying felzartamab in adults with Immunoglobulin A nephropathy IgAN, a kidney disease caused by abnormal IgA antibodies building up in the kidneys leading to inflammation and damage. This Phase 3 clinical trial aims to understand how felzartamab affects proteinuria, the presence of protein in urine, and kidney function in people with IgAN. The safety and how the body processes felzartamab are also being evaluated. Participants will be randomly assigned to receive either felzartamab or a placebo through intravenous infusions during a 24-week treatment period. Some participants with lower kidney filtration rates will be grouped separately but also receive either felzartamab or placebo. After treatment, participants will enter an 80-week follow-up phase. In total, participants will have 17 study visits over about two years. Throughout the study, participants will have urine tests to measure proteinuria, blood tests to assess kidney filtration function, and monitoring for side effects. Researchers will also study felzartamab levels in the blood and check for immune reactions against the drug. Safety will be closely monitored using vital signs, laboratory tests, and physical exams during the entire 104-week period.
