Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track
  • Composite eligibility for CAR-T cell therapy: ECOG ≤2 AND adequate organ function (LVEF ≥40%, CrCl ≥30 mL/min, bilirubin ≤2× ULN, AST/ALT ≤5× ULN, no severe pulmonary disease) AND no active uncontrolled CNS disease AND adequate bridging plan available AND no active uncontrolled infection. Used to gate referral to axi-cel, brexu-cel, liso-cel, tisa-cel, ide-cel, cilta-cel. RF-CAR-T-ELIGIBLE
  • Progression on covalent BTK inhibitor (ibrutinib, acalabrutinib, zanubrutinib). Triggers selection of non-covalent BTKi (pirtobrutinib), BCL2i (venetoclax-based regimens), CAR-T (lisocabtagene maraleucel, brexucabtagene autoleucel), or PI3Ki — depending on disease (CLL, MCL, WM). Resistance often driven by BTK C481S or PLCG2 mutation. RF-PRIOR-BTKI-PROGRESSION

CONTRA-AGGRESSIVE

Hard contraindications to escalation
  • Alemtuzumab causes profound, prolonged CD4+ T-cell depletion (median recovery 9-12 months). Active uncontrolled infection at baseline becomes life-threatening once cellular immunity collapses. HIV-positive status is itself an absolute contraindication — alemtuzumab on top of HIV immunosuppression has unacceptable infectious mortality. CI-ACTIVE-INFECTION-FOR-ALEMTUZUMAB

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity
Standard plan (IND-MCL-3L-PIRTOBRUTINIB)
  • Do not prescribe without verified prior cBTKi exposure — Cat 2A indication restricts use to post-cBTKi setting.
  • Do not stop on transient AE without reassessment — for post-cBTKi MCL alternatives are few.
  • Do not skip baseline ECG + cardiology assessment — afib reduced but possible.
  • Do not combine with anticoagulants without strict monitoring — bleeding risk persists.
  • Do not prescribe with concomitant strong CYP3A4 inhibitor without dose reduction to 100 mg PO QD.
  • Do not confirm plan without funding pathway — drug not registered in Ukraine.
  • Do not forget progression monitoring — for TP53-mut or blastoid MCL, early CAR-T-referral planning is recommended, even during pirtobrutinib bridge.
Aggressive plan (IND-MCL-3L-BREXUCEL-CART)
  • Do not prescribe prophylactic systemic corticosteroids — suppresses CAR-T expansion + reduces efficacy.
  • Do not start without on-site tocilizumab (minimum 2 doses) BEFORE infusion — fatal CRS possible.
  • Do not perform at a center without CAR-T accreditation (FACT/JACIE/REMS) — toxicity management requires a specialized team + ICU access.
  • Do not skip baseline brain MRI — pre-existing CNS disease risk of fatal ICANS significantly higher (higher in MCL than DLBCL).
  • Do not ignore bridging therapy — TP53-mut or blastoid MCL progresses fast in the 3-4 wk manufacturing window.
  • Do not prescribe with active uncontrolled infection — lymphodepletion + CRS = high mortality.
  • Do not use axi-cel instead of brexu-cel — leukemic-phase MCL apheresis contamination problematic without CD19-depletion process step.
  • Do not forget IVIG for long-term hypogammaglobulinemia (IgG <400 + recurrent infections).

  • Surveillance for relapse (median PFS years for both regimens)
  • Watch for Richter transformation (rapid LDH rise, new B-symptoms, isolated mass) — re-biopsy
  • Second primary malignancy screening
