This research study is a Phase I clinical trial. The investigators are studying the combination of the B-cell receptor (BCR) pathway inhibitors with ricolinostat, in order to try to enhance both the initial remission and to help improve the response in those who relapse after a first inhibitor and are receiving a second.~The FDA (the U.S. Food and Drug Administration) has not approved ACY-1215 as a treatment for any disease. ACY-1215 or ricolinostat is a histone deacetylase inhibitor, specifically HDAC6. The FDA has approved idelalisib as well as ibrutinib as treatment options for Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL).
This research study is studying a drug called ACY-1215 in combination with ibrutinib or idelalisib as a possible treatment for Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL).
