Study Details

Study Description

Brief Summary

This is a multicenter, open-label, non-randomized, phase II clinical trial conducted in Canada. The purpose of the study is to determine the remission rate of acalabrutinib in combination with R-CHOP in patients with previously untreated mantle cell lymphoma prior to autologous stem cell transplantation. All patients will receive six cycles of R-CHOP chemotherapy together with continuous acalabrutinib at the standard dose twice per day orally. All patients will undergo response assessment at the end of six cycles of R-CHOP + acalabrutinib with CT scan, PET/CT scan, and bone marrow biopsy. Responding patients will proceed with stem cell mobilization, apheresis, and processing. Following ASCT, patients will receive standard maintenance rituximab every 3 months for 2 years.

Outcome Measures

Primary Outcome Measures

  1. Complete response (CR) rate by PET/CT scan using Lugano Classification for Malignant Lymphoma [1-2 weeks after completing six cycles (21 days) of R-CHOP + acalabrutinib.]

Secondary Outcome Measures

  1. Adverse events of acalabrutinib and R-CHOP by using CTCAE version 5.0 [Baseline through end of study treatment (up to 18 weeks)]

  2. Measures of efficacy by using the RECIL 2017 criteria. [Baseline to end of study (up to 2 years)]

  3. Rate of minimal residual disease negativity (MRD) prior to transplant by flow cytometry [Up to 18 weeks]

  4. Event-free in patients who discontinue acalabrutinib at the point of MRD negativity prior to transplant by flow cytometry [Baseline to end of study (up to 2 years)]

  5. Changes in scores of partient reported outcomes (PRO) as measured by FACT-Lym [Baseline to end of study (up to 2 years)]

    Composed of the FACT-G plus the 15-item Lymphoma Subscale (LymS).

  6. Overall survival in patients who discontinue acalabrutinib at the point of MRD negativity [Baseline to end of study (up to 2 years)]

  7. Changes in scores of partient reported outcomes (PRO) as measured by FACT-Cog [Baseline to end of study (up to 2 years)]

    Participants rated their cognitive function on a scale of 0 to 4 where 0 was never and 4 was several times a day.

  8. Changes in scores of partient reported outcomes (PRO) as measured by EORTC QLQ-C30 [Baseline to end of study (up to 2 years)]

    Participants rated their quality of life on a scale of 1 to 4 where 1 was not at all and 4 was very much.

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years and Older
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  1. Men and women ≥ 18 years of age deemed eligible for treatment with full-dose R-CHOP and ASCT by the qualified investigator.

  2. Histologic diagnosis of MCL according to the World Health Organization classification

  3. Previously untreated MCL with the following exceptions: (a) prior radiotherapy for localized disease, (b) up to 7 days of corticosteroids (prednisone 100mg/day equivalent), (c) up to one dose of single-agent chemotherapy (for example, cyclophosphamide), (d) up to one cycle of R-CHOP or bendamustine-rituximab (BR). Patients with exceptions (c) and (d) are eligible as long as all other eligibility criteria are met AND at least a CT scan and bone marrow biopsy were performed prior to chemotherapy.

  4. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.

  5. Presence of at least one radiologically measurable nodal or extranodal mass. A measurable nodal mass must have a longest diameter ≥1.5 cm. A measurable extranodal mass should have a longest diameter ≥1.0 cm.

  6. Women of childbearing potential (WOCBP) who are sexually active must use highly effective methods of contraception during treatment and up to 12 months after the last dose of rituximab or R-CHOP, or 2 days after the last dose of acalabrutinib, whichever is last administered. Examples of highly effective contraceptive methods include an agreement to remain abstinent (ie, refrain from heterosexual intercourse), bilateral tubal ligation, male sterilization, established proper use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. Men who are sexually active must use highly effective methods of contraception during treatment and up to 6 months after the last dose of rituximab or R-CHOP, or 2 days after the last dose of acalabrutinib, whichever is last administered. Men require an agreement to remain abstinent (ie, refrain from heterosexual intercourse) or use a condom, and an agreement to refrain from donating sperm. Periodic abstinence and withdrawal are not acceptable methods of contraception. Fertility preservation options should be discussed.

  7. Willing and able to participate in all required evaluations and procedures in this study protocol including swallowing capsules without difficulty.

  8. Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information
