Abstract
- e22504 Background: Pediatric/YA pts with r/r B-NHL are rare and have heterogenous, aggressive histology and poor prognosis. We report early results for tisagenlecleucel (anti-CD19 CAR-T cell therapy) in pediatric/YA pts with r/r B-NHL. Methods: BIANCA (NCT03610724) is a phase 2, single-arm, global, open-label trial of tisagenlecleucel in pediatric/YA pts with CD19+ r/r B-NHL. Pts must have confirmed mature B-NHL r/r to ≥1 prior lines of therapy and no active CNS involvement. Primary endpoint is ORR. Secondary outcomes include DOR, EFS, safety and pharmacokinetics. Results: As of Nov 4, 2019, 8 pts were enrolled, of whom 4 had large B-cell lymphoma (LBCL), 3 Burkitt lymphoma (BL), and 1 gray zone lymphoma (GZL) (Table). Five pts had ≥2 lines of prior therapy. Suitable apheresis product was harvested in all 8 pts. Five pts were infused and 3 were pending infusion at data cut off. Product was successfully manufactured within specifications for all infused pts. Median time from enrollment to infusion was 33 days (range 30-67). All 5 pts have ≥28 days follow up; 2 pts have ≥3 months follow up (median [range] 85 days [69-97]). All 8 pts received bridging chemotherapy (including 1 pt who also had surgery and 1 who also had radiotherapy). Tisagenlecleucel dose range was 0.3-1.1 × 108 CAR+ viable T cells (weight-based: 0.9-1.7 × 106 CAR+ viable T cells/kg). Cmax (range: Cmax= 8520-14,200 copies/µg; time to Cmax= 2-21 days; n = 4) was within range of expansion observed in pediatric/YA acute lymphoblastic leukemia and adult diffuse LBCL. All 5 pts had CRS; no grade ≥3 CRS was recorded. Three pts had neurologic events, including 2 grade 3/4 events. One pt died due to disease progression. Conclusions: Pediatric/YA pts with r/r B-NHL (including BL) were successfully infused with tisagenlecleucel in the BIANCA trial with a manageable safety profile. Apheresis/manufacturing were feasible in this cohort of rapidly progressing disorders. Tisagenlecleucel was shown to expand in vivo. BIANCA provides the first systematic data on CAR-T cell therapy in highly aggressive, pediatric/YA B-NHL. Planned enrollment is 35 pts (26 infused and evaluable). Clinical trial information: NCT03610724. [Table: see text]
