Summary

This early-stage study tests a new drug called AC676 in about 60 adults with certain blood cancers (like leukemia or lymphoma) that returned or didn't respond to prior treatments. The main goals are to find a safe dose and understand side effects. Researchers will also check how the drug moves through the body and whether it can shrink tumors.
