3L Trial

An open-label, single-arm trial (N=269)1
TRANSCEND trial: Largest pivotal trial in 3L+ large B-cell lymphoma, including patients with high-risk disease2

Primary endpoints: ORR and safety2
Select secondary endpoints: CR, DOR, and OS2

Bridging therapy prior to receiving Breyanzi® was optional.1
Complete remission achieved for majority of patients1

The IRC-assessed overall response rate in the leukapheresed population (N=287) was 59% (95% CI: 53, 64), with a CR rate of 43% (95% CI: 37, 49) and PR rate of 15% (95% CI: 11, 20).1*
Efficacy was established on the basis of CR rate and DOR, as determined by an Independent Review Committee per the Lugano 2014 criteria.
Breyanzi is administered as a one-time treatment1
* Of the 287 patients who underwent leukapheresis and had radiographically evaluable disease, 27 additional patients achieved a response, apart from the responses noted in graph above. These efficacy results include responses that may have been contributed solely by bridging therapy, product outside of the intended dose range, and out-of-spec product.
Treatment process includes leukapheresis, manufacturing, administration, and adverse event monitoring. A single dose of Breyanzi is 90 to 110 × 106 CAR-positive viable T cells for LBCL after 1 line of prior therapy, and 50 to 110 × 106 for LBCL after 2 or more lines of therapy (consisting of 1:1 CAR-positive viable T cells of the CD8 and CD4 components), with each component supplied separately in 1 to 4 single-dose vials.
Breyanzi demonstrated rapid and durable remission1

  • OS was a secondary endpoint of TRANSCEND and was not statistically tested in the setting of a single-arm trial
  • OS data are not in the USPI and should be interpreted with caution in a single-arm trial. The statistical significance of OS is not known
  • OS included survival data from patients who completed TRANSCEND and enrolled in the subsequent long-term follow-up study

TRANSCEND trial2

The trial included both patients who had previous stem cell transplants and patients who did not undergo transplant due to ineligibility or other reasons. There was no prespecified threshold for blood counts; patients were eligible to enroll if they were assessed to have adequate bone marrow function to receive LDC.1
  • Primary endpoints: ORR, safety2
  • Select secondary endpoints: CR, DOR, OS2
TRANSCEND trial design and patient disposition1
Of 299 patients who underwent leukapheresis:
  • 44 (15%) did not receive CAR-positive T cells either due to manufacturing failures (n=2), death (n=29), disease complications (n=6), or other reasons (n=7)
  • 204 (68%) received Breyanzi in the intended dose range, of whom 192 were evaluable for efficacy (main efficacy population); 12 were not evaluable due to absence of PET-positive disease at study baseline or after bridging therapy
  • 51 (17%) either received Breyanzi outside of the intended dose range (n=26) or received CAR‑positive T cells that did not meet the product specifications for Breyanzi (manufacturing failures; n=25)
Patients were allowed to receive bridging therapy prior to receiving Breyanzi. Optional bridging therapy for disease control included intrathecal chemotherapy or radiation therapy for treatment of CNS lymphoma.1
25 patients were treated in an outpatient setting per physicians’ discretion1
