Conditions

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a single center, open-label, phase II study of venetoclax (ABT-199) added to ibrutinib or acalabrutinib in patients with high-risk CLL who have received at least 12 months of ibrutinib or acalabrutinib monotherapy. The study will estimate the therapeutic efficacy of venetoclax consolidation in patients who have detectable CLL after receiving ibrutinib or acalabrutinib for at least 12 months and who have high risk CLL.

Inclusion Criteria	Exclusion Criteria
1. Patients must have a diagnosis of CLL/CLL and have high-risk cytogenetic features or molecular features, defined as: del(17p), mutated TP53, complex metaphase karyotype (defined as 3 unrelated chromosomal abnormalities, present in at least 2 metaphases on conventional, stimulated cytogenetic analysis) 2. Patients must have received at least 12 months of ibrutinib or acalabrutinib therapy and have measurable CLL by at least one of the following: * Absolute monoclonal lymphocyte count \> 4000/L; OR * Measurable lymph nodes with at least one node \>1.5 cm in diameter on CT; OR * Bone marrow with \>/= 30% lymphocytes on aspirate differential OR * Detectable CLL cells using a standardized flow cytometry assay for minimal residual disease 3. Age 18 years or older. 4. Eastern Cooperative Oncology Group (ECOG) Performance Status ≤2. 5. Patients must have adequate renal and hepatic function: * Serum bilirubin ≤1.5 x upper limit of normal (ULN) or ≤3 x ULN for patients with Gilbert's disease. * Serum creatinine clearance of 50ml/min (calculated or measured). * ALT and AST ≤3.0 x ULN, unless clearly due to disease involvement. 6. Adequate bone marrow function: * Platelet count of greater than 50,000/µl, with no platelet transfusion in prior 2 weeks. * ANC ≥1000/µl in the absence of growth factor support unless due to compromised bone marrow production from CLL, indicated by 80% CLL in marrow. * Hemoglobin ≥8mg/dL. 7. INR \<1.5. 8. Adequate cardiac function, as assessed by: * Absence of uncontrolled cardiac arrhythmia. * Echocardiogram demonstrating LVEF ≥35%. * NYHA functional class ≤2. 9. Ability to provide informed consent and adhere to the required follow-up. 10. Women of childbearing potential must have a negative serum or urine beta human chorionic gonadotropin (β-hCG) pregnancy test result within 7 days prior to the first dose of study drugs and must agree to use use both a highly effective method of birth control (eg, implants, injectables, combined oral contraceptives, some intrauterine devices \[IUDs\], complete abstinence , or sterilized partner) and a barrier method (eg., condoms, vaginal ring, sponge, etc) during the period of therapy and for 30 days after the last dose of study drug. Women of non-childbearing potential are those who are postmenopausal (defined as absence of menses for ≥1 year) or who have had a bilateral tubal ligation or hysterectomy. Men who have partners of childbearing potential must agree to use effective contraception, defined above, during the study and for 30 days following the last dose of study drug. 11. Patients or their legally authorized representative must provide written informed consent.	1. Richter transformation. 2. Active malignancy requiring systemic therapy, other than CLL, with the exception of: adequately treated in situ carcinoma of the cervix uteri; adequately treated basal cell carcinoma or localized squamous cell carcinoma of the skin; previous malignancy confined and surgically resected (or treated with other modalities) with curative intent. 3. Major surgery, radiotherapy, chemotherapy, biologic therapy, immunotherapy, experimental therapy within 3 weeks prior to the first dose of the study drug. 4. Grade 3 or 4 hemorrhage within the past 3 weeks. 5. Uncontrolled active infections (viral, bacterial, and fungal). 6. Females who are pregnant or lactating. 7. Known positive serology for human immunodeficiency virus (HIV). 8. Active hepatitis B infection (defined as the presence of detectable HBV DNA or HBe antigen). Patients who are HBsAg positive or HBcAb positive are eligible, provided HBV DNA is negative. These patients will have monthly monitoring of HBV DNA for the duration of the study, if clinically indicated. Please note that patients who have received IVIG may have false positive HBcAb results. In such patients, if HBV DNA and HBsAg are negative, serial HBV DNA monitoring is not necessary. 9. Active hepatitis C, defined by the detection of hepatitis C RNA in plasma by PCR. 10. Active, uncontrolled autoimmune phenomenon (autoimmune hemolytic anemia or immune thrombocytopenia) requiring steroid therapy \>20mg prednisone daily or equivalent, within 7 days of starting venetoclax. 11. Received other investigational therapeutic agent for CLL/SLL within 21 days of starting venetoclax. 12. Concurrent use of warfarin. 13. Received strong CYP3A inhibitors or strong CYP3A inducers within 7 days of starting venetoclax. 14. Consuming grapefruit, grapefruit products, Seville oranges, or star fruit within 7 days of starting venetoclax. 15. Prior treatment with venetoclax or other Bcl-2 inhibitor. 16. Malabsorption syndrome or other condition that precludes enteral route of administration
