ALL PATIENT CASE (2L)

Act urgently following relapsed/refractory B-ALL with TECARTUS

Headshot of a female representing
TECARTUS® patient.
Clinical considerations

59-year-old female with B-cell acute lymphoblastic leukemia (B-ALL)

  • Immunohistochemistry: CD19+, CD20+, and CD22+
  • Cytogenetics: Ph-negative
  • BM biopsy: 65% blasts

MRD: Persistent positive by flow cytometry

LDH: 520 U/L

ECOG PS: 1

Comorbidities: None significant

Clinical fitness
  • Cardiac function: LVEF 55%
  • Renal function: CrCl 80 mL/min
  • Liver function: Mild AST/ALT elevation
Treatment History
Newly diagnosed ALL First line:
  • Hyper-CVAD (progression within 11 months)
Results:
  • Bone marrow biopsy confirms relapse with rising lymphoblasts after frontline therapy
Comments:
  • Relapsed/refractory disease after frontline treatment
  • High disease burden (increased blasts, increased LDH)
  • Rapid progression following prior therapy
  • Clinically fit with preserved organ function
Treatment Considerations:
  • Limited treatment options with durable responses in R/R ALL
  • Rapid disease progression requires timely intervention
  • Eligible for CAR T, given ECOG 1 and preserved organ function
  • Early referral critical to avoid further clinical deterioration

ALL PATIENT CASE (MRD POSITIVE)

Early CAR T consultation and recognition of persistent MRD may help identify patients who could benefit from timely referral for TECARTUS before relapse occurs

Clinical considerations

41-year-old male with B-cell acute lymphoblastic leukemia (B-ALL)

  • Immunohistochemistry: CD19+, CD22+
  • Cytogenetics: Ph-negative
  • BM biopsy: <5% blasts (morphologic remission)

MRD: Persistent positive by flow cytometry

LDH: 240 U/L

Clinical fitness
  • Cardiac function: LVEF 62%
  • Renal function: CrCl 95 mL/min
  • Liver function: WNL
  • ECOG PS: 0
  • Comorbidities: Mild HTN
Treatment History
Newly diagnosed ALL Induction and consolidation:
  • Hyper-CVAD + rituximab → Morphologic CR
Maintenance:
  • Persistent MRD positivity after consolidation
  • Received blinatumomab → MRD persistence
Results:
  • Persistent MRD despite sequential therapy
  • No overt morphologic relapse, but concern for impending progression
  • Referred early while clinically stable and fit
Comments:
  • Persistent MRD associated with increased relapse risk
  • Young, functionally fit patient with preserved organ function
  • Early referral may offer opportunity for CAR T before overt clinical deterioration
  • Motivated to pursue a potentially durable treatment approach
Treatment Considerations:
  • MRD persistence suggests high-risk disease despite morphologic remission
  • Additional sequential therapy may not overcome resistant disease biology
  • Eligible for CAR T given ECOG PS 0 and preserved organ function
