New hope for leukemia patients who Can't tolerate standard treatment
NCT ID NCT02717611
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a drug called ACP-196 (acalabrutinib) in 60 adults with chronic lymphocytic leukemia (CLL) whose cancer returned or didn't respond to treatment and who had to stop ibrutinib because of side effects. The main goal is to see how many patients have their tumors shrink or disappear. Participants take the drug by mouth, and researchers track how long the benefits last and any side effects.

Exception: Subjects with controlled, asymptomatic atrial fibrillation during screening are allowed to enroll on study. 6. Malabsorption syndrome, disease significantly affecting gastrointestinal function, resection of the stomach, extensive small bowel resection that is likely to affect absorption, symptomatic inflammatory bowel disease, partial or complete bowel obstruction, or gastric restrictions and bariatric surgery, such as gastric bypass. 7. Evidence of active Richter's transformation or any evidence of disease progression on ibrutinib therapy or any BTK inhibitor. 8. CNS involvement by CLL or related Richter's transformation. 9. Known history of human immunodeficiency virus (HIV), serologic status reflecting active hepatitis B or C infection, or any uncontrolled active systemic infection. 10. Uncontrolled autoimmune hemolytic anemia (AIHA) or idiopathic thrombocytopenic purpura (ITP) 11. History of stroke or intracranial hemorrhage within 2 months before the first dose of study drug. 12. History of bleeding diathesis. 13. Presence of a gastrointestinal ulcer diagnosed by endoscopy within 3 months before screening. 14. Major surgical procedure within 28 days of first dose of study drug. 15. Requires treatment with a strong CYP3A inhibitor
