Acalabrutinib With DA-EPOCH-R or R-CHOP for People With Untreated Diffuse Large B-cell Lymphoma

• Status: Recruiting
• Trial end date: 2028-03-31
• Target enrollment: 0
• Participant gender: All

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.

Criteria

-INCLUSION CRITERIA:

1. Patients must have a confirmed histologic diagnosis of an aggressive B-cell lymphoma with morphologic appearance of DLBCL or high-grade B-cell lymphoma (HGBL) confirmed by the Laboratory of Pathology, NCI, with no prior treatment for DLBCL or HGBL. The following subtypes are included:

• DLBCL, NOS, Activated B-cell type (ABC)

• DLBCL, NOS, Germinal center B-cell type (GCB)

• T-cell/histiocyte-rich large B-cell lymphoma

• Primary cutaneous DLBCL, leg-type

• EBV+ DLBCL, NOS

• DLBCL associated with chronic inflammation

• ALK+ large B-cell lymphoma

• High-grade B-cell lymphoma, NOS

• High-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 rearrangements

NOTE: Presence of concomitant indolent lymphomas such as follicular lymphoma, marginal zone lymphomas, monoclonal B-cell lymphocytosis or chronic lymphocytic leukemia/small lymphocytic lymphoma that are best categorized as composite or transformed lymphomas are allowed.

2. 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).

3. Measurable lymph nodes or masses of at least 1.5 centimeters (cm) on baseline CT or MRI

4. Stage II, III, or IV disease as classified by the Ann Arbor Classification

5. Age greater than or equal to 18 years

6. ECOG performance status less than or equal to 2.

7. 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

• hemoglobin* >= 8 g/dL (transfusions permitted to meet criteria)

• Platelets >= 75,000/mcL (transfusions not permitted)

• total bilirubin <= 1.5 X institutional ULN (or <= 3 X institutional ULN for patients with documented Gilberts syndrome or cholestatic obstruction or involvement by lymphoma)

• AST(SGOT)/ALT(SGPT) <= 3 X institutional ULN (<= 5 x ULN for patients with cholestatic obstruction or involvement by lymphoma

• Serum creatinine <= 2.0 mg/dL

OR

-Creatinine clearance >=40 mL/min/1.73 m2 for patients with creatinine levels above 2 mg/dL

*RBC transfusions and use of G-CSF will be allowed in order to meet eligibility parameters.

NOTE: In patients without bone marrow involvement, transfusions of RBCs are permitted to achieve the criterion hemoglobin of 8g/dl, but transfusions of platelets are not permitted to achieve the criterion platelet count of >75,000/mcL. In patients with bone marrow involvement, all transfusions are permissible at the discretion of the investigator.

8. Effects of acalabrutinib on the developing human fetus are unknown. For these reasons the following measures apply:

• Women of childbearing potential must have a negative serum or urine pregnancy test within 7 days prior to enrollment.

• Women of childbearing potential (WOCBP) who are sexually active must agree to highly-effective contraception (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for at least 2 days after the last dose of acalabrutinib or 12 months after the last dose of combined chemotherapy, whichever is later. 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.

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.

6. Requires treatment with moderate or strong CYP3A inhibitors or inducers

7. Known lymphomatous involvement of the CNS

8. Pregnant women, or women who intend to become pregnant during the study are excluded from this study because of potential teratogenic effects associated with acalabrutinib, R-CHOP, and/or DA-EPOCH-R

9. The potential for all study treatments to be excreted in breast milk of nursing mothers is unknown. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with acalabrutinib, breastfeeding must be discontinued.

11. Uncontrolled intercurrent illness including, but not limited to the following that may limit interpretation of results or that could increase risk to the patient at the discretion of the investigator:

• Uncontrolled active systemic infection

• Any condition that requires anticoagulation with warfarin or equivalent vitamin K antagonist

• Active bleeding, history of bleeding diathesis (e.g., hemophilia or von Willebrand disease)

• Suspected or confirmed Progressive Multifocal Leukoencephalopathy (PML)

• Active hepatitis B infection. NOTE: Patients who are hepatitis B surface antigen (HbcsAg) or hepatitis B core antibody (HbcAb) positive will need to have a negative HBV PCR result before enrollment. Those with a positive PCR for hepatitis B are excluded. Those who are hepatitis B surface antigen (HbcsAg) or hepatitis B core antibody (HbcAb) positive with a negative PCR for hepatitis B will be treated with antivirals designed to prevent hepatitis B reactivation (e.g., entecavir) throughout therapy and for 12 months after therapy and have monitoring for hepatitis B reactivation with PCR.

• Diagnosed or treated for malignancy other than DLBCL, except:

1. Malignancy treated with curative surgical resection and no evidence of active disease for 2 years prior to enrollment

Subjects with controlled atrial fibrillation/flutter during screening are eligible.

• Uncontrolled autoimmune hemolytic anemia

• Inability to swallow oral medications, or disease involve that significantly limits absorption of oral medication

• Known mental or physical illness that would interfere with cooperation with the requirements of the trial or confound the results or interpretation of the results of the trial and, in the opinion of the treating investigator, would make the patient inappropriate for entry into the study.
