A Phase 1/2, open-label, multicenter, single-arm trial

Breyanzi®: THE ONE to deliver deep and durable responses in 3L+ CLL or SLL1

Primary endpoints: ORR (including CR and PR) and DOR1

Select secondary endpoints: safety, uMRD, PFS, and OS2

Patients were allowed to receive bridging therapy.1

The study population consisted mainly of patients with difficult-to-treat disease, with 83% having high-risk features* and 51% having bulky disease.1†

Breyanzi demonstrated deep and durable complete responses, with 87.5% of CRs maintained at 18 months1

Median PFS of 12 months was observed in TRANSCEND CLL 0043‡

Graph of median progression-free survival (PFS) rates of Breyanzi 3L+ CLL/SLL patients in the TRANSCEND CLL 004 clinical trial

Analysis limitations:

  • PFS data are not in the Prescribing Information and should be interpreted with caution
  • PFS was a secondary endpoint in TRANSCEND CLL 004 and was not statistically tested in the setting of a single-arm trial. It is not possible to determine if the observed effect is attributable to Breyanzi or to the natural history of the disease2
  • The statistical significance of PFS is not known

mPFS was not reached in patients who achieved a CR3

Median OS of 33.6 months was observed in TRANSCEND CLL 004

Graph of overall survival (OS) rates of 3L+ CLL/SLL patients in the TRANSCEND CLL 004 clinical trial
  • mOS was not reached in patients who achieved a CR3
  • mOS was 33.6 months (95% CI: 19.9, NR)3

Analysis limitations:

  • OS data are not in the Prescribing Information and should be interpreted with caution
  • OS was a secondary endpoint in TRANSCEND CLL 004 and was not statistically tested in the setting of a single-arm trial. It is not possible to determine if the observed effect is attributable to Breyanzi or to the natural history of the disease2
  • The statistical significance of OS is not known
