Summary

This phase II trial studies the effect of acalabrutinib and obinutuzumab in treating patients with follicular lymphoma or other indolent non-Hodgkin lymphoma for which the patient has not received treatment in the past (previously untreated). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with obinutuzumab may induce changes in body's immune system and may interfere with the ability of cancer cells to grow and spread. Giving acalabrutinib and obinutuzumab may kill more cancer cells.

Description

PRIMARY OBJECTIVE:

I. To determine if treatment acalabrutinib and obinutuzumab is effective in patients with untreated, low tumor burden follicular lymphoma and other indolent non-Hodgkin lymphomas (NHLs).

SECONDARY OBJECTIVES:

I. Determine the complete response (CR) rate for single agent acalabrutinib at the end of a single-agent run-in for patients with untreated low tumor burden follicular lymphoma (FL).

II. Determine tolerability of acalabrutinib and obinutuzumab via assessment of patient-reported outcomes and conventional assessments.

III. Assess duration of response and long-term outcomes including progression-free survival.

IV. Assess the impact of early treatment with this regimen on health-related quality of life.

TERTIARY/EXPLORATORY OBJECTIVES:

I. Evaluate the impact of treatment discontinuation in patients who have achieved a complete response at the end of the induction phase.

II. To assess the safety and efficacy of acalabrutinib and obinutuzumab in other subtypes of indolent NHL.

OUTLINE

INDUCTION PHASE: Patients receive acalabrutinib orally (PO) twice daily (BID) on days 1-28. Patients also receive obinutuzumab intravenously (IV) on days 1, 8, and 15 of cycle 3, then on day 1 of cycles 4-8. Treatments repeat every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

FOLLOW-UP PHASE: After cycle 12, patients who are in CR are randomized to either discontinue acalabrutinib or to continue acalabrutinib monotherapy in the absence of disease progression or unacceptable toxicity. Patients with partial response (PR) or stable disease (SD) after cycle 12 continue acalabrutinib monotherapy in the absence of disease progression or unacceptable toxicity. Patients with disease progression after cycle 12 discontinue study treatment. Patients with disease progression at any time prior to the conclusion of cycle 12 may continue study therapy if they are felt to be benefiting by the treating physician, but not past cycle 12.

After completion of study treatment, patients are followed up at 30 days, every 12 weeks for 1 year, then every 6 months until disease progression or next anti-lymphoma treatment.

Eligibility

Yes No Not Sure

Inclusion Criteria

Men and women >= 18 years of age
Patients will need to have one of the following clinical scenarios
Previously untreated follicular lymphoma grade 1-3a with low tumor burden by Groupe d'Etude des Lymphomes Folliculaires (GELF) criteria
Previously untreated follicular lymphoma grade 1-3a with high tumor burden by GELF criteria but who are unable or unwilling to receive standard front-line treatment approaches
Previously untreated marginal zone lymphoma, lymphoplasmacytic lymphoma, or any other indolent B-cell lymphoproliferative disorder with low tumor burden by GELF criteria or who are unable/unwilling to receive more intensive front-line treatment
Previously untreated mantle cell lymphoma who would otherwise be appropriate candidates for watchful waiting OR who have symptomatic disease but are not candidates for or decline standard induction approaches
Patients with previously untreated low tumor burden FL (criterion above) must have
measurable and/or assessable disease defined as at least one involved lymph
node or extranodal disease site that measures >= 1.5cm in greatest diameter
Patients who meet inclusion criteria above are eligible as long as they meet one of the following criteria for measurable/assessable disease
At least one involved lymph node or extranodal disease site measuring > 1.5cm in greatest diameter
Pathologically-confirmed bone marrow or peripheral blood involvement that can be reassessed for response
Pathologically confirmed splenic or extranodal involvement with at least one known site of disease remaining after diagnostic biopsy that can be reassessed (i.e., patients with splenic marginal zone lymphoma who complete splenectomy and have no other detectable disease would not be eligible)
Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
Woman of childbearing potential (WOCBP) and men enrolled on this protocol must agree to use adequate contraception (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 18 months after the last dose of obinutuzumab, whichever is longer. 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
Women of childbearing potential must have a negative serum or urine pregnancy test prior to starting therapy
Willing and able to participate in all required evaluations and procedures in this study protocol
Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information

Exclusion Criteria

Prior receipt of lymphoma-directed therapy or prior antibody-based therapy (except for anti-microbial therapy for infection-associated marginal zone lymphoma such as hepatitis C or H pylori)
A short course of steroids is permitted for patients aside from those in the low tumor burden FL cohort. This course may be no more than 14 days and steroids must be discontinued (or tapered to =< 10mg prednisone or equivalent) no later than 3 days after initiation of study treatment. Patients in the low tumor burden FL cohort may not receive corticosteroids as an anti-lymphoma therapy at any time before starting treatment
