MCL should have CD20 positivity (by flow or IHC in tissue or in BM) with presence of chromosome translocation t (11;14), (q13;q32) and/or overexpression of cyclin D1 in tissue biopsy. Cyclin D negative MCL are allowed after discussion with study PI.
- Participants should have a life expectancy >= 12 weeks.
- Newly diagnosed, untreated, high risk participant without any prior therapy for MCL and are eligible to receive BTKi-R and glofitamab therapy.
- High risk MCL (Blastoid/pleomorphic histology, high Ki-67 (≥50%), TP53/NOTCH1/2, NSD2, UBR5, TRAF2, SP140, SMARCA4, KMT2D, BIRC3 mutated or any of these mutations or more than 2 mutations with some evidence of prognostic impact, complex karyotype and/or Bulky nodal disease >= 5 cm or spleen >= 20 cm, FISH positive for TP53 or MYC from involved tissues or TP53 and MYC positive intensity in lymphoma cells in involved tissues (positive by hem-path criteria at MDACC), high risk MIPI score (with/without Ki-67%). Presence of any or all of these features would qualify as high risk but will need to be reviewed and approved by the study PI.
6. Participants who are willing and able to participate in all required evaluations and procedures in this study protocol, including swallowing capsules and tablets without difficulty.
7. Understand and voluntarily sign an IRB-approved informed consent form. 8. Age ≥ 18 years at the time of signing the informed consent. 9. Bi-dimensional measurable disease using the 2014 Cheson criteria (Measurable disease by PETCT scan or CT scan (if PET-CT not approved and study PI approves) defined as at least 1 lesion that measures ≥ 1.5 cm in single dimension.) and/or spleen only involved (>=20 cm). Leukemic phase MCL are allowed without bulky measurable disease if they have other high-risk features after discussion with the study PI. These participants are allowed if they meet any other high-risk features, determined by the study PI.
10. Eastern Cooperative Oncology Group (ECOG) performance status of 1 or less. 11. Participants with preexisting well-controlled cardio-vascular comorbidities - participants on anticoagulants (excluding warfarin and vitamin K antagonists), antiplatelet, antihypertensive, prior ablation, anti-arrhythmia, prior arrhythmias, baseline EKG abnormalities and cardiology clearance are allowed. Ejection fraction >=50% and cardiology evaluation is needed. (Echo and EKG and cardiology consultation within 2 months prior to C1D1 are allowed).
12. An absolute neutrophil count (ANC) > 1,000/mm3 and platelet count >100,000/mm3 (Participants who have >50% bone marrow or spleen infiltration by MCL are eligible if their ANC is ≥ 500/mm3 [growth factor allowed] or their platelet level is equal to or >= than 30,000/mm3 (transfusions allowed) These participants should be discussed with the PI of the study for final approval). Hemoglobin > 8.0 g/dL (> 80 g/L), unsupported for 2 days before first treatment (unless attributable to the underlying disease as determined by the study PI) 13. Serum bilirubin <1.5 mg/dl, AST (SGOT) and ALT (SGPT) < 2.5 x upper limit of normal or < 5 x upper limit of normal if hepatic metastases are present. Gilbert's disease is allowed.
14. Creatinine clearance. >=30 mL/min (by 2021 chronic kidney disease epidemiology (CKD-EPI) creatinine equation or 2021 CKD-EPI creatinine-cystatin C equation., APPENDIX VI I) 15. Contraception in female participants of childbearing potential- female participants must remain abstinent or use contraceptive methods with a failure rate of < 1% per year during the treatment period and for at least 6 months after pretreatment with obinutuzumab, 2 months after the final dose of glofitamab and 2 months after the final dose of tocilizumab (as applicable), whichever is longer. Women must refrain from donating eggs during this same period.
16. A female participant is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (³ 12 continuous months of amenorrhea with no identified cause other than menopause), and is not permanently infertile due to surgery (i.e., removal of ovaries, fallopian tubes, and/or uterus) or another cause as determined by the investigator (e.g., Müllerian agenesis). Per this definition, a female participant with tubal ligation is considered to be of childbearing potential. The definition of childbearing potential may be adapted for alignment with local guidelines or regulations.
17. Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation in female of child-bearing potential, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.
18. Hormonal contraceptive methods are also recommended to be supplemented by a barrier method.
19. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the individual. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not adequate methods of contraception. If required per local guidelines or regulations, locally recognized adequate methods of contraception and information about the reliability of abstinence will be described in the local Informed Consent Form.
20. Contraception for male participants: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods, and agree to refrain from donating sperm, as defined below: 21. With a female partner of childbearing potential or pregnant female partners, male participants must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 6 months after pretreatment with obinutuzumab, 2 months after the final dose of glofitamab or 2 months after the last dose of tocilizumab (as applicable), whichever is longer. Male participants must refrain from donating sperm during this same period.
22. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the individual. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not adequate methods of contraception. If required per local guidelines or regulations, locally recognized adequate methods of contraception and information about the reliability of abstinence will be described in the local Informed Consent Form. ..
a. Females must agree to abstain from breastfeeding during study participation and for at least 12 months after glofitamab discontinuation. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test. WOCBP and males must be willing to use highly effective methods of birth control. Woman of childbearing potential (WOCBP) who are sexually active must use highly effective methods of contraception during treatment and 1 week after the last dose of acalabrutinib b. Females of childbearing potential (FCBP§ ) must: i. Have one negative pregnancy tests via serum in some cases urine (as clinically indicated) one week or immediately prior to starting study therapy. She must agree to ongoing pregnancy testing during the course of the study, prior to day 1 of each cycle, and after end of study therapy. This applies even if the subject practices true abstinence* from heterosexual contact.
ii. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice. Otherwise, she must agree to use, and be able to comply with highly effective contraception.
c. Male subjects must: i. A male subject who is sexually active with a female with reproductive potential is also recommended to use a barrier method of birth control, eg, either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ suppository (including dose interruptions), even if they have undergone a successful vasectomy, from the time of signing consent and for at least 2 months after the last dose of glofitamab, 6 months after treatment with obinutuzumab, or 2 months after the last dose of tocilizumab (if applicable), whichever is longer. For male participants with a pregnant or non-pregnant WOCBP partner, should use barrier contraception, during treatment and for 1 week after the last dose of acalabrutinib, 180 days following the last dose of rituximab, 2 months following the last dose of glofitamab,6 months following the last dose of obinutuzumab, 2 months following the last dose of tocilizumab (if applicable), , whichever is longer, even if they have had a successful vasectomy.) d.
