New hope for tough blood cancers: experimental drug AC676 enters human testing
NCT ID NCT05780034
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.

Inclusion Criteria: 1. Adult male and female patients, at least 18 years-of-age at the time of signature of the informed consent form (ICF). 2. Patients with histologically confirmed relapsed/refractory Chronic Lymphocytic Leukemia (CLL), Small Lymphocytic Lymphoma (SLL), Mantle Cell Lymphoma (MCL), Follicular Lymphoma (FL), non-GCB Diffuse Large B-cell Lymphoma (DLBCL), Marginal Zone Lymphoma (MZL), or Waldenström Macroglobulinemia (WM). 3. Must have received at least 2 prior systemic therapies or have no other therapies to provide significant clinical benefit in the opinion of the Investigator or who are not amenable (intolerability, patient choice) to standard therapies. Exclusion Criteria: Patients who meet any of the following criteria will be excluded from study entry: 1. Treatment with any of the following: * Small molecule anti-cancer drugs within 5 half-lives or 2 days (whichever is longer, not to exceed 14 days). * Systemic chemotherapy within 14 days. * Radiation therapy within 14 days * Biologics (Antibodies) treatment within 28 days, * Radioimmunoconjugates or toxin conjugates within 12 weeks. * Prior Chimeric antigen receptor (CAR) T cell therapy (and prior use of immunoglobulin replacement therapy to treat associated adverse events) within 3 months. For patients with DLBCL, no prior CAR- T therapy is allowed. * Autologous or allogenic stem cell transplant within 100 days and must not have ongoing graft-versus-host disease (GVHD) and no ongoing therapy to treat GVHD. 2.
