LB1908 / Legend Biotech - LARVOL DELTA

Preliminary results of a phase 1 study of LB1908, an autologous Claudin 18.2–targeted chimeric antigen receptor T-cell product, in patients with advanced gastroesophageal adenocarcinoma. (ASCO 2025) - P1 | "Bridging therapy was administered to all patients between apheresis and LB1908 infusion, and patients received standard lymphodepletion (LD) with cyclophosphamide/fludarabine... LB1908 demonstrates peripheral expansion and encouraging antitumor activity at the lowest dose tested, with a manageable safety profile. Implementation of a toxicity mitigation strategy ameliorated on-target gastric mucosal injury without compromising expansion kinetics or antitumor activity. Longer follow-up and data from patients treated with higher cell doses will be presented at the meeting."

LB1908: Preliminary results of a Phase 1 study of a CLDN18.2-targeted CAR T-cell therapy show manageable safety and antitumor activity in patients with gastroesophageal cancers (Abstract #4022) (GlobeNewswire) - P1 | N=56 | NCT05539430 | Sponsor: Legend Biotech USA Inc | "Interim data from a Phase 1, first-in-human, open-label, multicenter study of LB1908, an autologous CAR-T targeting Claudin 18.2, were presented in patients with advanced gastric, gastroesophageal, and esophageal adenocarcinoma (GC/GEJC/EC) who are relapsed or refractory to one or more prior line of therapy and whose tumors express CLDN18.2 in 50% or more tumor cells....LB1908 demonstrated peripheral expansion and early signs of antitumor activity at the lowest dose tested, with a manageable safety profile. A toxicity mitigation strategy was implemented to address on-target gastric mucosal injury, which successfully reduced toxicity without compromising CAR-T expansion or antitumor activity. Additional data, including longer follow-up and outcomes from patients treated at higher dose levels, were also presented."

A phase 1, open-label, dose escalation and expansion, multicenter study of claudin 18.2-targeted chimeric antigen receptor T-cells in patients with unresectable, locally advanced, or metastatic gastric, gastroesophageal junction, esophageal, or pancreatic adenocarcinoma. (ASCO-GI 2023) - P1 | "Subjects may receive optional bridging therapy followed by lymphodepleting chemotherapy with fludarabine 30 mg/m2/day and cyclophosphamide 300 mg/m2/day for 3 days...Secondary and exploratory endpoints include: objective response rate, disease control rate, duration of response, progression-free survival, characterization of PK by CAR-positive T cell counts, CAR transgene level in blood, effusions, and target tissues, and evaluation of immunogenicity by presence of anti-LB1908 antibodies. Acknowledgments: This study is funded by Legend Biotech USA Inc. Clinical trial information: NCT05539430."
