Summary

Background

Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma. Most people with this cancer can be cured. But those who are not cured have a poor prognosis. Researchers want to add another drug to standard treatment see if it can improve the cure rate.

Objective

To see if the drug acalabrutinib given with rituximab and standard combination chemotherapy can improve the cure rate of aggressive B-cell lymphomas such as diffuse large B-cell lymphoma.

Eligibility

People ages 18 and older with an aggressive B-cell lymphomas that have not been treated

Design

Participants will be screened with:

Blood and urine tests

Physical exam

Medical history

Tumor biopsy

Bone marrow biopsy: A needle will remove marrow from the participant s hipbone.

Lumbar puncture: If necessary, a needle will remove fluid from the participant s spinal canal.

Imaging scans

Participants will take the study drug for up to 14 days. It is a pill taken 2 times a day. Then they will have more scans. They will get rituximab and chemotherapy. They may get these drugs through a needle in an arm vein. Or they may them through a tube placed in a vein in their chest or in their neck. They might also keep taking the study drug. Each treatment cycle lasts 21 days. They will have up to 6 cycles.

Participants may have 4 doses of another drug injected into their spinal fluid.

Participants will have repeats of the screening tests throughout the study.

Participants will have a follow-up visit 30 days after their last treatment, then every 3 months for 2 years, then every 6 months for 3 years, and then yearly.

Description

Background
  • Gene-expression profiling (GEP) has identified two dominant molecular subtypes,activated B cell like (ABC) and germinal center B cell like (GCB), that arise by distinct mechanisms, have distinct prognoses, and respond differently to targeted therapy
  • Recently, genetic subtypes of DLBCL have been described within molecular subtypes that have distinct genotypic, epigenetic, and clinical characteristics providing biologic rationale for precision medicine strategies in DLBCL
  • Frontline treatment of DLBCL is either rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP), or infusional rituximab, cyclophosphamide, doxorubicin, etoposide, vincristine, and prednisone (DA-EPOCH-R) but up to 40% of patients are not cured with frontline treatment
  • Bruton s tyrosine kinase (BTK) is a key component of the B-cell receptor (BCR)-signaling cascade and selective BTK inhibitors have clinical activity preferentially in ABC-DLBCL
  • Acalabrutinib is a selective, small molecule, second-generation BTK inhibitor approved for relapsed mantle cell lymphoma and demonstrated activity in DLBCL
  • The molecular characterization of tumors that respond to DLBCL BTK inhibitors is incomplete; although responses occur more commonly in ABC-DLBCL, cases of GCBDLBCL show minor responses, and no information is available within genetic subtypes of DLBCL
  • Patients with minor responses during 2-week window of treatment with acalabrutinib (100mg BID) as a single agent may benefit from acalabrutinib added to standard combination therapy as part of frontline therapy
    Objectives

-To determine the response rate, including minor response (MR), to acalabrutinib administered for 14 days in molecular and genetic subtypes of untreated DLBLC (ABC, GCB, unclassified, genetic subtypes)

Eligibility
  • Histologically confirmed DLBCL or high-grade B-cell lymphoma
  • Primary mediastinal B-cell lymphoma (PMBL) and CNS involvement excluded
  • Stages II-IV
  • HIV negative or positive
  • Available FFPE or fresh frozen biopsy
  • Adequate organ function
  • Age >=18 years
Design
  • Open-label, single center, non-randomized phase 2 study, with enrollment of 100 untreated DLBCL patients. It is estimated that there may be 50% who are ABC (~50 patients), and 50% who are GCB or unclassified (~50 patients). The accrual ceiling will be set at 132 to allow for inevaluable patients and to account for screen fails.
  • The study will start with an initial 2-week window of treatment with acalabrutinib (100mg BID) as a single agent, with collection and assessment of molecular correlates as well as response rates (by imaging) by molecular subtype
  • Treatment with chemoimmunotherapy (R-CHOP or DA-EPOCH-R) either alone or in combination with acalabrutinib will depend on response during window; those with less than 25% reduction during window will receive chemoimmunotherapy alone, while those with at least a 25% reduction in tumor lesions (sum of the products of the longest diameter) will receive combination therapy of chemoimmunotherapy with acalabrutinib (100mg BID on days 1-10 of each cycle); those with clinical progression during window will move immediately to chemoimmunotherapy
  • Secondary objectives include integrative genomic analysis of all untreated DLBCL that respond or are resistant to acalabrutinib for 14 days, event-free survival (EFS), progression free survival (PFS) and overall survival (OS) of combination therapy of acalabrutinib and chemoimmunotherapy will be assessed

A formalin-fixed tissue block or 15 slide of tumor sample (archival or fresh) must be available for performance of correlative studies
NOTE: Tumor tissue may be from any previously collected tissue and adequacy is
at the discretion of the Principal Investigator. Patients must be willing to
have a tumor biopsy if adequate archival tissue is not available (i.e., post-
enrollment and prior to treatment)
\. Measurable lymph nodes or masses of at least 1.5 centimeters (cm) on
baseline CT or MRI
\. Stage II, III, or IV disease as classified by the Ann Arbor Classification
\. Age greater than or equal to 18 years

use of acalabrutinib in patients <18 years of age, children are excluded
\. ECOG performance status less than or equal to 2
\. Adequate organ and marrow function as defined below unless dysfunction is
felt to be secondary to lymphoma involvement as determined by the treating
investigator
absolute neutrophil count >=1,000/mcL

Male subjects must use highly effective contraception prior to study entry, for the duration of study participation, and for 12 months after the last dose of combined chemotherapy; there is no contraception timing requirement post-last dose of acalabrutinib alone if male subject does not initiate chemotherapy on study after the acalabrutinib window
Participants must not be planning to conceive or father children within the projected duration of the trial, starting with the pre-screening/screening visit through 2 days after the last dose of acalabrutinib or 12 months after the last dose of combined chemotherapy, whichever is later
Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
WOCBP is defined as any female who has experienced menarche and who has not undergone successful surgical sterilization or who is not postmenopausal (i.e., amenorrheic for >12 months without alternative medical cause; post-menopausal status in females under 55 years of age should be confirmed with a serum folliclestimulating hormone [FSH] level within applicable local laboratory reference range for postmenopausal women). 9. Ability of patient to understand and the willingness to sign a written informed consent document. 10. Any HIV status will be included in this study; status must be confirmed prior to enrollment
