Résumé
Tafasitamab plus lenalidomide (TAFA-LEN) treatment relevance pre- or post-anti-CD19 CAR T-cell is currently debated. We analyzed large B-cell lymphoma patients in the DESCAR-T registry treated with axi-cel or tisa-cel in ≥3rd line (L3+) and TAFA-LEN before (n=15, 'TL-pre-CAR-T' set) or directly after (n=52, 'TL-post-CAR-T' set) CAR T-cell. We compared TAFA-LEN v. other treatments using inverse probability weighting in the TL-post-CAR-T set. In the TL-post-CAR-T' set, the median follow-up duration (mFUD) was 7 months, and the median progression-free survival, overall survival and duration of response since the 1st treatment for progression (mPFS2/mOS2/mDOR2) were 3, 4.7 and 8.1 months, respectively. The best overall response rate (bORR) and best complete response rate (bCRR) after TAFA-LEN were 13.5% and 7.7%, respectively. Outcomes were better for patients who relapsed >6 months after CAR T-cell (mPFS2: 5.6 vs. 2 months, p=0.0138; mOS2: not reached vs. 3.8 months, p=0.0034). bORR and bCRR between TAFA-LEN and other treatments were 20.6% vs. 24.9% and 11.6% vs. 15.6%, respectively. Outcomes were similar between TAFA-LEN and other treatments (mPFS2: 2.9 [2-2.6] vs. 2.4 [1.5-4.2] months, p=0.91; mOS2: 3.3 [1.8-6.4] vs. 5.5 [4.4-6.3] months, p=0.06). In an exploratory analysis of the TL-pre-CAR-T set (mFUD since CAR T-cell: 2.8 months), the median TAFA-LEN treatment duration prior to CAR-T was 3.7 months and no patients were reported to become CD19 negative. The bORR, bCRR, 6-month PFS and OS rates after CAR T-cell infusion were 45.5%, 36.4%, 20.1% and 58.2%, respectively. Neither TAFA-LEN nor comparative salvage treatments improved outcomes of patients who relapsed after CAR T-cell.
