About this trial

The Double-T trial is a prospective, randomized, single-arm, open-label, multicenter phase II trial investigating a double T-cell therapy strategy, which includes glofitamab with gemcitabine/oxaliplatin (Glofi-Gem/Ox) prior to and glofitamab monotherapy consolidation after standard of care Chimeric Antigen Receptor (CAR)-T cell therapy in high-risk 2nd line relapsed/refractory Large B-Cell Lymphoma (r/r LBCL) patients.

Data on safety, efficacy, and quality of life (QoL) will be collected and analyzed.

Eligibility criteria

Patient has histologically confirmed diagnosis of large B-cell lymphoma by local pathologist at time of relapse.

Patient received R-CHOP based first-line therapy containing a CD20-antibody and anthracyclines.

Disqualifiers

Patient has HIV infection of any stage as determined by presence of anti-HIV antibodies (confirmatory test) and / or presence of RNA confirmed by PCR during screening

Surgically cured carcinoma in-situ

Trial outcomes

Primary outcomes

1

CRR@EOT

Complete response rate (CRR) at end of treatment (CCR@EOT), defined as proportion of patients who achieved complete response (CR) at the end of trial treatment (EOT) as per Lugano classification

Time frame
at the end of trial treatment, on average after 10 months

Secondary outcomes

1

CCR@pIT and CCR@3MpCT

CRR post induction (CCR@pIT) and at 3 months post-CAR-T cell infusion (CCR@3MpCT), defined as proportion of patients who achieved complete response after two cycles induction treatment and 3 months after CAR-T cell infusion as per Lugano classification

Time frame
post induction (after 6 weeks) and 3 months post-CAR-T cell infusion (after 4,5 months)
2

Overall CRR

Overall CRR, defined as proportion of patients who achieved CR as best overall response (BOR)

Time frame
from first Investigational Medicinal Product (IMP) administration until end of follow-up, on average 2,5 years
3

ORR post induction, at 3 months post-CAR-T cell infusion, and at EOT

Objective Response rate (ORR) post induction (OOR@pIT), at 3 months post-CAR T cell infusion (ORR@3MpCT) and at end of trial treatment (ORR@EOT), defined as proportion of patients who achieved complete or partial response (CR/PR) after 2 cycles of induction treatment, at 3 months after CAR-T cell infusion and at the end of the treatment

Time frame
post induction (after 6 weeks), at 3 months post-CAR-T cell infusion (after 4,5 months), and at end of trial treatment (on average after 10 months)
