Venetoclax and Acalabrutinib in Treating Patients with Relapsed or Refractory Mantle Cell Lymphoma

Trial Status: Active

This phase II trial studies the safety and efficacy of venetoclax and acalabrutinib combination in treating patients with mantle cell lymphoma that did not respond to previous treatment (refractory) or has come back (recurrent). Venetoclax may cause cancer cell death by blocking the mechanism that cancer cells use to stay alive. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving combination of venetoclax and acalabrutinib may help control mantle cell lymphoma.

Inclusion Criteria

  • Confirmed diagnosis of previously treated relapsed/refractory patients MCL with CD5+, CD23-, CD20+ and chromosome translocation t(11;14), (q13;q32) and/or overexpress cyclin D1 in tissue biopsy (blastoid/pleomorphic morphology, complex karyotype is acceptable).

  • Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less.
  • Absolute neutrophil count (ANC) > 1,000/mm^3 independent of growth factor support.
  • Platelet count >= 100,000/mm^3 or >= 50,000/mm^3 if bone marrow involved with lymphoma, independent of transfusion support in either situation.
  • Creatinine (Cr) =< 2 or Cr clearance >= 30 mL/min.
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3 x upper limit of normal (ULN).
  • Serum bilirubin < 1.5 mg/dl, unless due to Gilbert’s syndrome, documented liver involvement with lymphoma, or of non-hepatic origin.
  • Prothrombin time (PT)/international normalized ratio (INR) =< 1.5 x ULN and partial thromboplastin time (PTT) =< 1.5 x ULN.
  • Disease free of prior malignancies other than MCL with exception of currently treated basal cell, squamous cell carcinoma of the skin, carcinoma "in situ" of the cervix or breast, or other malignancies in remission (including prostate cancer patients in remission from radiation therapy, surgery or brachytherapy), not actively being treated with life expectancy of > 3 years. Principal investigator (PI) can use clinical judgement in the best interest of patients.
  • Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test and willing to use highly effective methods of birth control. A female of childbearing potential is a sexually mature woman who: * Has not undergone a hysterectomy or bilateral oophorectomy; or * Has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).

Exclusion Criteria

  • Any serious medical condition including but not limited to, uncontrolled hypertension, uncontrolled diabetes mellitus, active/symptomatic coronary artery disease, chronic obstructive pulmonary disease, renal failure, active hemorrhage, or psychiatric illness that, in the investigator's opinion places the patient at unacceptable risk and would prevent the subject from signing the ICF.
  • Pregnant or breast-feeding females.
  • Known human immunodeficiency virus (HIV) infection.
  • Uncontrolled autoimmune hemolytic anemia (AIHA) or idiopathic thrombocytopenic purpura (ITP).
  • Patients with active hepatitis B infection (not including patients with prior hepatitis B vaccination; or positive serum hepatitis B antibody). Known hepatitis C infection is allowed as long as there is no active disease and is cleared by gastrointestinal (GI) consultation.
  • Central nervous system (CNS) disease with serious significance.
  • Malabsorption syndrome, disease significantly affecting GI function, or resection of the stomach or small bowel or ulcerative colitis, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction, or any other GI condition that could interfere with the absorption and metabolism of acalabrutinib or venetoclax.
  • Major surgery or a wound that has not fully healed within 4 weeks of initiation of therapy.
  • Known bleeding diathesis (e.g., von Willebrand’s disease) or hemophilia.
  • History of stroke or intracranial hemorrhage within 6 months prior to study entry.
  • Requires anticoagulation with warfarin or equivalent vitamin K antagonist.
  • Vaccinated with live, attenuated vaccines within 4 weeks of study entry.
  • Concurrent systemic immunosuppressant therapy (e.g., cyclosporine, tacrolimus, etc., or chronic administration of > 10 mg/day of prednisone or equivalent) within 28 days of the first dose of study drug.
  • Requires treatment with strong CYP3A inhibitors or inducers or strong CYP1A2 inhibitors.
  • Refractory to prior ibrutinib or BTK mutation or previous exposure to ibrutinib.
  • Patients with New York Heart Association (NYHA) class III and IV heart failure, myocardial infarction in the preceding 6 months, and significant conduction abnormalities, including but not limited to left bundle branch block, 2nd degree atrioventricular (AV) block type II, 3rd degree block, sick sinus syndrome, ventricular tachycardia, symptomatic bradycardia (heart rate < 50 beats per minute [bpm]), hypotension, light headedness and syncope, persistent and uncontrolled atrial fibrillation.
  • Recent placement of a stent (within last 12 months) and by recommendation of their cardiologist need to stay on anticoagulants such as warfarin or equivalent vitamin K antagonist or anti-platelet agents.
  • Exclude patients with active ongoing infections requiring intravenous (IV) antimicrobials.
  • Requires treatment with proton-pump inhibitors (e.g., omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole or pantoprazole). Subjects receiving proton-pump inhibitors who switch to H2-receptor antagonists or antacids are eligible for enrollment to this study.

PRIMARY OBJECTIVE:

I. To evaluate the efficacy of a combination of venetoclax and acalabrutinib, in patients with previously treated relapsed/refractory mantle cell lymphoma (MCL).

SECONDARY OBJECTIVES:

I. To evaluate the efficacy of this combination regimen in previously treated subjects with relapsed/refractory MCL with overall response rate (ORR), duration of response (DOR), event free survival (EFS), progression free survival (PFS), and overall survival (OS).

II. To evaluate the safety and tolerability of venetoclax and acalabrutinib in previously treated subjects with relapsed/refractory MCL.

CORRELATIVE/TRANSLATIONAL COMPONENT OBJECTIVES:

I. Sequential peripheral blood (PB)/plasma/tissue fine needle aspirate will be stored.

II. Clonal evolution with targeted sequencing (seq) and/or whole exome sequencing (WES) in sequential samples.

III. Pattern of mutation changes with Bruton tyrosine kinase inhibitor (BTKi) or with venetoclax resistance.

IV. Response predictors – mutations, cytokine-chemokines, clonal evolution (CE).

V. Minimal residual disease (MRD) assay using circulating tumor deoxyribonucleic acid (ctDNA) analysis, flow cytometry at various time points from peripheral blood (PB)/ bone marrow (BM).

VI. Sequential immunologic studies with cytokines/chemokines, T cell numbers, and immunoglobulins (Ig).

VII. Tissue microenvironmental studies with simultaneous assessment of PB, BM and lymph nodes for gene expression profiling (GEP), single cell seq, ribonucleic acid (RNA) seq and clonal heterogeneity and the impact of acalabrutinib - venetoclax (A-V) treatment.

OUTLINE: This is a study to evaluate the effectiveness and safety of venetoclax and acalabrutinib combination therapy.

Patients receive acalabrutinib orally (PO) twice daily (BID) on days 1-28. Starting cycle 2 day 1, patients also receive venetoclax PO daily. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up within 30 days, then every 4 months for 2 years, then every 6 months for the next 2 years, and then annually thereafter.
