3L+ R/R LBCL

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 disease1

Primary endpoints: ORR and safety2
Secondary endpoints: CR, DOR, and OS2

Bridging therapy prior to receiving Breyanzi® was optional.1

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 IRC per the Lugano 2014 criteria.1

Of the 104 patients who achieved CR, 68 (65%) had remission lasting at least 6 months, and 64 (62%) had remission lasting at least 9 months1
Median DOR for PR: 1.4 months (95% CI: 1.1, 2.2)1
*Treatment process can take approximately 2 to 3 months and includes leukapheresis, manufacturing, administration, and adverse event monitoring.1
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-specification.1
Kaplan-Meier method was used to obtain 2-sided 95% confidence intervals.1

Analysis limitations:
  • OS data are not in the Prescribing Information and should be interpreted with caution
  • OS was a secondary endpoint in TRANSCEND 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 disease
  • The statistical significance of OS is not known

TRANSCEND trial2
Trial design of Breyanzi TRANSCEND clinical trial
Trial design of Breyanzi TRANSCEND clinical trial
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 and safety2
  • Select secondary endpoints: CR, DOR, and 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’ discretion2
