MMRC Horizon One Adaptive Platform Trial Evaluating Therapies in RRMM
Recruiting
This trial is an adaptive platform trial. The structure of the protocol allows the trial to evolve over time. Multiple investigational arms will be included within the trial under a Master Protocol (MP). These investigational arms may be added as appendices at different times depending on whether they are trial-ready and whether accrual in the trial will support another arm. Accrual to an arm will terminate in accord with the arm's appendix to the Master Protocol. The purpose of this proposed s... Read More

A Study to Learn More About the Safety and Effects of Felzartamab in Adults With Lupus Nephritis Aged 18 to 75 Years Old
Recruiting
In this study, researchers will learn more about the use of felzartamab in people with active lupus nephritis, also known as LN. In people with LN, antibodies build up in the glomeruli of the kidneys. Antibodies are proteins in the blood used by the immune system to fight infection. Glomeruli are small filters that remove waste and extra fluid from the blood. This buildup leads to inflammation and damage to the kidneys. Kidney damage can lead to too much protein and blood leaking into the urine... Read More
