New hope for tough cancers: first human test of experimental drug begins

This is an early-stage study to test the safety and find the right dose of a new experimental drug, JAB-8263, in adults with advanced cancers that have not responded to standard treatments. The trial will enroll about 152 people with various advanced solid tumors (like lung or ovarian cancer) or blood cancers (like leukemia). The main goals are to see how much of the drug the body can handle, check for side effects, and get an early look at whether it might help shrink tumors.
