A Pilot "Window-3" Study of Acalabrutinib Plus Rituximab Followed by Brexucabtagene Autoleucel Therapy in Patients With Previously Untreated High-risk Mantle Cell Lymphoma

Running, not enrolling · Early Phase 1

Conditions studied: Lymphoma, Mantle Cell Lymphoma

In brief

To learn if giving acalabrutinib, rituximab, and brexucabtagene autoleucel to patients with previously untreated high-risk mantle cell lymphoma (MCL) can help to control the disease.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Confirmed diagnosis of mantle cell lymphoma by hematopathology. MCL should have CD20 positivity (by flow or IHC in tissue or in BM) with presence of chromosome translocation t(11;14), (q13;q32) and/or overexpression of cyclin D1 in tissue biopsy (See Appendix I, footnote 10).
• Newly diagnosed high risk patient without any prior therapy for MCL and are eligible to receive AR and CART cell therapy.
• High risk MCL (Blastoid/pleomorphic histology, high Ki-67 (≥50%), TP53/NOTCH1/2, NSD2, UBR5, FAT1, TRAF2, SP140, POT1, SMARCA4, KMT2D, BIRC3 mutated or any of these mutations or more than 2 mutations with some evidence of prognostic impact, complex karyotype and/or Bulky disease >= 5 cm, FISH positive for TP53 or MYC from involved tissues or TP53 and MYC positive intensity in lymphoma cells in involved tissues (positive by hem-path criteria at MDACC), high risk MIPI score (with Ki-67%). Presence of any or all of these features would qualify as high risk but will need to be reviewed and approved by the study PI. (We will not use any assay which is not FDA approved or not CLIA certified to determine the eligibility of these patients)
• Patients who are eligible to receive CAR T therapy
• Patients who are willing and able to participate in all required evaluations and procedures in this study protocol, including swallowing capsules and tablets without difficulty.
• Understand and voluntarily sign an IRB-approved informed consent form.
• Age ≥ 18 years at the time of signing the informed consent.
• Bi-dimensional measurable disease using the 2014 Cheson criteria (Measurable disease by PET-CT scan defined as at least 1 lesion that measures ≥ 1.5 cm in single dimension.) Spleen only involved (>=20 cm), these patients are allowed if they meet other high-risk features, determined by the study PI.
• Eastern Cooperative Oncology Group (ECOG) performance status of 1 or less (See Appendix IV).
• An absolute neutrophil count (ANC) > 1,000/mm3 and platelet count >100,000/mm3 (Patients who have >50% bone marrow or spleen infiltration by MCL are eligible if their ANC is ≥ 500/mm3 [growth factor allowed] or their platelet level is equal to or >= than 30,000/mm3. These patients should be discussed with the PI of the study for final approval).
• Serum bilirubin <1.5 mg/dl and Cr Clearance ≥ 60 mL/min by Cockroft-Gault Formula (Appendix VIII) or by >=60 ml/min by 24 hour urine Cr clearance test (Appendix VIII) , AST (SGOT) and ALT (SGPT) < 2.5 x upper limit of normal or < 5 x upper limit of normal if hepatic metastases are present. Gilbert's disease is allowed.
• Women of childbearing potential (WOBP) must have a negative serum or urine pregnancy test. WOBP and males must be willing to use highly effective methods of birth control. Woman of childbearing potential (WOCBP) who are sexually active must use highly effective methods of contraception during treatment and for 2 days after the last dose of acalabrutinib and for 12 months following the last dose of rituximab and 6 months after the completion of CAR T infusion. For male patients with a pregnant or non-pregnant WOCBP partner, should use barrier contraception, during treatment and for 2 days after the last dose of acalabrutinib and for 1 month following the last dose of rituximab and 6 months after the completion of CAR T infusion even if they have had a successful vasectomy. (see Appendix VII).
• Cardiology cleared for receiving acalabrutinib and CART
• EXCLUSION CRITERIA PART 1:
• Isolated bone marrow or GI only disease MCL patients and/or lack of measurable disease.
• Pregnant or breast-feeding females.
• Patients who are primary refractory to AR (No response/progressive disease within first 4 months of AR)
• Received any investigational drug within 30 days or 5 half-lives (whichever is shorter) before first dose of study drug.
• Current life-threatening illness, medical condition, or organ system dysfunction which, in the Investigator's opinion, could compromise the subject's safety or put the study at risk.
• Known HIV infection.
• Patients who do not meet high risk features as indicated above. Hepatitis B or C serologic status: subjects who are hepatitis B core antibody (anti-HBc) positive and who are hepatitis B surface antigen (HBsAg) negative will need to have a negative polymerase chain reaction (PCR) and must be willing to undergo DNA PCR testing during the study to be eligible. Those who are HBsAg positive or hepatitis B PCR positive will be excluded. Subjects who are hepatitis C antibody positive will need to have a negative PCR result to be eligible. Those who are hepatitis C PCR positive will be excluded.
• Prior malignancy (or any other malignancy requiring active treatment), except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, in situ ca prostate, in situ melanoma (> 5 mm margins) or other cancer from which the subject has been disease free for ≥ 3 years or which will not limit survival to < 3 years.
• Central nervous system involvement with mantle cell lymphoma or with suspected or confirmed progressive multifocal leukoencephalopathy (PML). Magnetic resonance imaging (MRI) of the brain, if performed, showing evidence of central nervous system (CNS) lymphoma or Lumbar puncture with flow cytometry, if performed, with CSF involvement.
• History or presence of CNS disorder, such as seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, cerebral edema, posterior reversible encephalopathy syndrome, or any autoimmune disease with CNS involvement.
• Active bleeding, history of bleeding diathesis (such as Hemophilia or Von-Willebrand disease), Any history of intracranial bleed or stroke within 6 months of first dose of study drug.
