A Study of AC676 for the Treatment of Relapsed/Refractory B-Cell Malignancies

Summary

This clinical trial is evaluating a drug called AC676 in participants with Relapsed/Refractory B-cell Malignancies. The main goals of the study are to: * Identify the recommended dose of AC676 that can be given safely to participants * Evaluate the safety profile of AC676 * Evaluate the pharmacokinetics of AC676 * Evaluate the effectiveness of AC676

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:
