A Phase 1 Dose Escalation Trial of Third-Generation CD19-Directed CAR T-Cells Incorporating CD28 and Toll-like Receptor 2 (TLR2) Intracellular Domains for Relapsed or Refractory B-Cell Non-Hodgkin Lymphomas (ENABLE)
(ASH 2023)
- P1 | "WZTL-002 CAR T-cells were administered intravenously after 3 days of fludarabine (30mg/m2/day) and cyclophosphamide (500mg/m2/day) lymphodepletion...Grade 1 – 2 CRS occurred in 13 patients (62%); 6 received tocilizumab and 3 dexamethasone... In this dose escalation trial of a novel third-generation CD19-directed CAR T-cell product that combines CD28 and TLR2 co-stimulatory domains for r/r B-NHL, we observed no severe CRS, no ICANS of any grade and complete responses at all dose levels. At RP2D, in vivo CAR T-cell expansion was similar to or greater than other CD19-directed products. In conjunction with preclinical findings, this study suggests interposition of a TLR2 domain between CD28 and CD3ζ domains may reduce CAR T-cell-related ICANS risk while retaining efficacy."

(ASH 2024)
- P1, P2 | "Bridging therapy was permitted between leukapheresis and lymphodepletion (fludarabine 30mg/m2/day & cyclophosphamide 500mg/m2/day ×3d); WZTL-002 CAR T-cells were given intravenously 2d later...Grade 1 or 2 CRS occurred in 17 patients (57%) no grade ≥3 CRS events occurred; 9 (30%) received tocilizumab and 3 (10%) dexamethasone for CRS...This safety profile could facilitate outpatient management, lower treatment costs and improve the patient experience of CAR T-cell therapy. A phase 2 trial of WZTL-002 as 2nd or 3rd line treatment for r/r LBCL has commenced (ENABLE-2, NCT06486051)."

WZTL-002 CAR T Cells Show Potential in Treatment of Relapsed or Refractory B-Cell NHL
(Blood Cancers Today)
- P1 | N=30 | ENABLE-1 (NCT04049513) | "WZTL-002 yielded a CR rate of 52% in the 21-patient dose escalation cohort and 56% in the 6-patient dose expansion cohort. Of those treated at the recommended phase 2 dose, the WZTL-002 had a geometric mean mean CAR T-cell level of 29,515 transgenes/μg genomic DNA, and CARs remained detectable at day 90 in 14 patients (88%)...Regarding CRS, grade 1/2 events occurred in 17 patients (57%), and no events of grade 3 or higher were observed. Of the patients who had CRS, nine (30%) received tocilizumab and three (10%) received dexamethasone as treatment. No patients in the study needed intensive care within 28 days of receiving WZTL-002."

Third-generation anti-CD19 CAR T-cells demonstrate efficacy without neurotoxicity in B-cell lymphoma phase 1 clinical trial
(Eurekalert)
- P1 | N=30 | ENABLE (NCT04049513) | "The Malaghan Institute of Medical Research in collaboration with Wellington Zhaotai Therapies Limited today announced results of its phase 1 dose escalation trial of a new third generation anti-CD19 chimeric antigen receptor (CAR) T-cell therapy to be presented at the American Society of Hematology (ASH) Annual Meeting in San Diego on 11 December, 3pm....No dose limiting toxicities occurred at doses of 5 × 104 to 1 × 106 CAR T-cells/kg. Grade 1 or 2 CRS occurred in 13 patients (62%); no severe (grade ≥ 3) CRS occurred. Notably, no ICANS of any grade occurred. Clinical responses were seen at all dose levels, with a 3-month complete response rate of 52%. WZTL-002 CAR T-cell expansion was robust."

- P1 | N=30 | ENABLE (NCT04049513) | "The Malaghan Institute’s ENABLE phase 1 safety trial began in late 2019, in partnership with Wellington Zhaotai Therapies Ltd, treating 21 New Zealanders with relapsed or refractory B-cell non-Hodgkin lymphoma who had exhausted all conventional treatment options...The trial found no limiting toxicities at any of the doses tested. Importantly, none of the participants developed neurotoxicity or severe cytokine release syndrome – common side effects of some commercial CAR T-cell therapies. The trial also showed promising effectiveness, with around half of the participants’ lymphomas in complete response three months after receiving the treatment....'We are already treating patients in an ‘expansion cohort’, for which we have automated the CAR T-cell manufacturing process with our partners at BioOra, and we are giving the CAR T-cells as an outpatient therapy.'"

A phase 1 trial of TLR2-costimulated third-generation anti-CD19 CAR T-cells for relapsed/refractory B non-Hodgkin lymphomas
(BSH 2023)
- P1 | "Registry data indicate a CD28-costimulated anti-CD19 CAR T-cell product (axi-cel, 1928z) results in higher response rates, but more frequent neurotoxicity and severe cytokine release syndrome (CRS), than a 41BB-costimulated product (tisa-cel, 19BBz)...Following fludarabine and cyclophosphamide lymphodepletion, 5 × 10e4/kg to 1 × 10e6/kg autologous 1928T2z CAR T-cells were administered to 20 patients with relapsed or refractory B-cell non-Hodgkin lymphomas...Preliminary phase 1 clinical trial findings suggest third-generation 1928T2z CAR T-cells combine a low incidence of severe CRS and neurotoxicity with encouraging efficacy and robust expansion at low dose. Clinical investigation of 1928T2z CAR T-cells is ongoing."
