Healthy volunteers needed to test new drug interactions

This early-stage study looks at how two common drugs—itraconazole (a fungus treatment) and rifampin (an antibiotic)—change the way the body processes rocbrutinib, an experimental medicine. About 28 healthy adults will take rocbrutinib alone and then with each other drug to measure blood levels and safety. The goal is to gather information, not to treat any disease.
