Safety, tolerability, and preliminary efficacy results of a phase 1 study of LB2102, a dnTGFβRII armored DLL3-targeted autologous CAR-T cell therapy, in patients with relapsed or refractory small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC). (ASCO 2025) - P1 | "All subjects undergo 3-day lymphodepletion (LD) with fludarabine (30 mg/m2), and cyclophosphamide (300 mg/m2)... LB2102 has been well tolerated with no DLT observed up to DL3 (2 x 106 CAR+ T cells/kg). There appears to be a dose-dependent efficacy signal observed at higher doses with responses correlating to CAR-T expansion, although the data is limited. Given no DLTs and preliminary efficacy signal up to DL3, further exploration of higher dose levels is warranted."

Phase 1 Study of DLL3-Targeted CAR-T Cells Armored With dnTGFBR2 in Small-Cell Lung and Large-Cell Neuroendocrine Cancers (IASLC-WCLC 2025) - "Methods : This 3+3 dose-escalation study assesses safety, dose-limiting toxicities (DLTs), and efficacy of LB2102 across 7 dose-levels (0.3-16.0×10E6 CAR+T cells/kg) following fludarabine and cyclophosphamide lymphodepletion. A dose-dependent efficacy signal was observed; higher dose levels were associated with increased response rates, CAR-T expansion, and response duration. Evaluation at higher dose levels is warranted to assess LB2102's therapeutic potential."

LB2102 CAR T-Cell Therapy Is Well Tolerated, Yields Disease Control in R/R SCLC and LCNEC (OncLive) - P1 | N=41 | NCT05680922 | Sponsor: Legend Biotech USA Inc | "LB2102, a DLL3-directed autologous CAR T-cell therapy, was well tolerated without any dose-limiting toxicities (DLTs) observed up to dose level 4 (DL4), and it demonstrated preliminary antitumor activity in patients with relapsed/refractory small cell lung cancer (SCLC) and large cell neuroendocrine carcinoma (LCNEC), according to preliminary results from a phase 1 trial (NCT05680922) presented at the 2025 ASCO Annual Meeting. The best overall responses included partial responses (PRs) in 1 patient at dose level 3 (DL3) and 1 patient at DL4, and stable disease (SD) in 3 patients at dose level 2 (DL2), 2 patients at DL3, and 1 patient at DL4. In the overall population (n = 12), the objective response rate (ORR) was 16.7% with a disease control rate of 66.7%."

Safety and Efficacy of DLL3 CAR-T Cells Armored With dnTGFBR2 in a Patient With Recurrent Small-Cell Lung Cancer (IASLC-WCLC 2025) - "Methods : The patient (51 years old, female) had SCLC progression, symptomatic brain metastases, and a lung lesion approximately 8 months after starting platinum-based combination chemotherapy and 3 months after starting atezolizumab maintenance therapy...She received 2 cycles of irinotecan, given weekly as bridging therapy...After 1 day of lymphodepletion (fludarabine 30 mg/m 2 and cyclophosphamide 300 mg/m 2 ), she was excluded from the trial due to safety concerns from AMS (prior to LB2102 infusion)...The CAR-T cells expanded and persisted for more than 6 months. These findings warrant further research of DLL3-targeted autologous cell therapies for cancer."

dnTGF β RII-A rmored DLL3-Targeted CAR-T Cells Maintain TGF β Resistance with Early Signals of T-Cell Exhaustion Modulation After Expansion in SCLC (ASGCT 2025) - P1 | "LB2102 CAR VHHs demonstrated high specificity and no cross-reactivity to other DLL family members or unrelated proteins. LB2102 cells did not exhibit off-target killing in a panel of human primary cells (n=13). To assess whether dnTGFβRII expression confers resistance to TGFβ, LB2102 cells and unarmored LCAR-T20 cells were incubated with TGFβ1, and SMAD2 phosphorylation was assessed as a readout for TGFβ1-mediated signal transduction."

First Quarter 2025 Financial Results (GlobeNewswire) - "License revenue was $9.3 million for the three months ended March 31, 2025, compared to $12.2 million for the three months ended March 31, 2024. The decrease of $2.9 million was solely attributed to revenue recognized pursuant to Legend Biotech’s license agreement with Novartis for the development, manufacture, and commercialization of LB2102 and other potential CAR-T therapies selectively targeting DLL-3 (the 'Novartis License Agreement'). This revenue is recognized over time as Legend Biotech conducts a Phase 1 clinical trial for LB2102. The decrease resulted from the timing of the underlying activities performed in connection with such trial....Selling and distribution expenses were $41.0 million for the three months ended March 31, 2025, compared to $24.2 million for the three months ended March 31, 2024. The increase was due to increased costs associated with commercial activities including expansion of the sales force due to growing sales of CARVYKTI."
