Research outlook

Where mantle cell lymphoma treatment is heading

Mantle cell lymphoma · Updated Nov 14, 2026

About 4,000 people in the US are diagnosed with mantle cell lymphoma each year, mostly men in their 60s and 70s. It used to mean intensive chemotherapy and, for younger people, a stem-cell transplant. BTK inhibitor pills have changed that: they now improve survival when added to first treatment, can replace chemotherapy for older adults, and let many younger people skip transplant.

  1. Now

    Nov 2026

    Ibrutinib can replace a stem-cell transplantHappened 90% alive at 4 years

    In TRIANGLE, 4-year survival was 90% with ibrutinib and no transplant vs 81% with standard transplant.

    90%: alive at 4 years with ibrutinib and no transplant, vs 81% with standard transplant.

    Chemotherapy-free first treatment for older adultsHappened 0.69 hazard ratio

    Ibrutinib-rituximab cut the risk of progression or death by 31% compared with chemo-immunotherapy.

    0.69: hazard ratio for progression or death vs chemo-immunotherapy.

    A BTK pill added to first treatmentHappened 66.4 mo median progression-free

    Acalabrutinib plus bendamustine-rituximab: median progression-free survival 66.4 vs 49.6 months. FDA approved January 2025.

    66.4 mo: median progression-free survival, vs 49.6 months with placebo.

    A new pill after BTK inhibitors stop workingHappened

    Sonrotoclax, a next-generation BCL-2 inhibitor, won accelerated approval in May 2026.

  2. 6 months

    by May 2027

    Zanubrutinib-rituximab heads to regulatorsLikely

    MANGROVE beat bendamustine-rituximab as first treatment; filings were planned for late 2026.

  3. 12 months

    by Nov 2027

    Who can skip transplant, by blood testLikely

    ECOG-ACRIN EA4151 (689 people) tests skipping transplant in people with no detectable residual disease; due January 2027.

    A bispecific antibody after BTK inhibitorsPossible 78.3% complete responses (early study)

    GLOBRYTE compares glofitamab with standard choices for relapsed disease; due August 2027.

    78.3%: complete response rate.

    A reversible BTK pill vs older onesPossible

    BRUIN MCL-321 (500 people) compares pirtobrutinib with ibrutinib, acalabrutinib or zanubrutinib; due November 2027.

  4. 3 years

    by late 2029

    Next-generation pill combination at relapsePossible 31.9 mo with ibrutinib-venetoclax

    CELESTIAL-RRMCL (300 people) tests sonrotoclax plus zanubrutinib; due August 2028.

    31.9 mo: median progression-free survival, vs 22.1 months with ibrutinib alone.

  5. 5 years

    by late 2031

    Taking breaks from BTK pillsLong shot

    An Alliance trial (421 people) tests whether intermittent zanubrutinib works as well as continuous; long follow-up runs to 2038.
