News and Publications > SystImmune, Inc. to Present New Global Data on Iza-bren (izalontamab brengitecan) in EGFR-mutated Non-Small Cell Lung Cancer at WCLC Congress 2026 SystImmune, Inc. to Present New Global Data on Iza-bren (izalontamab brengitecan) in EGFR-mutated Non-Small Cell Lung Cancer at WCLC Congress 2026 September 12th, 2026 Redmond, Washington - New global Phase 1 data from a randomized dose-expansion cohort of iza-bren in previously treated EGFR-mutated metastatic NSCLC demonstrate promising antitumor activity and a tolerable safety profile, supporting selection of 2.5 mg/kg D1D8 Q3W as the recommended Phase 3 dose Redmond, WA - September 12, 2026 - SystImmune, Inc. (SystImmune), a clinical-stage biotechnology company, today announced an abstract for iza-bren (izalontamab brengitecan), a potentially first-in-class EGFRxHER3 bispecific antibody drug conjugate (ADC), will be presented in an oral presentation at the International Association for the Study of Lung Cancer (IASLC) 2026 World Conference on Lung Cancer (WCLC) taking place September 12 - 15 in Seoul, South Korea. Iza-bren is being developed under a license and collaboration agreement by and between SystImmune and Bristol Myers Squibb. The global Phase 1 data being presented at WCLC 2026 evaluated iza-bren in a randomized expansion cohort across three dose levels in patients with EGFR-mutated metastatic NSCLC who had previously received a third-generation EGFR inhibitor. The randomized dose-expansion results demonstrate promising clinical activity, with higher efficacy observed at the 2.5 mg/kg dose level with a manageable safety profile, and support 2.5 mg/kg D1D8 Q3W as the recommended Phase 3 dose for IZABRIGHT-Lung01, the global registrational study of iza-bren in EGFR-mutated NSCLC following progression on a third-generation EGFR inhibitor. The data further demonstrated the consistent efficacy and safety profile in a global population as shown previously in Chinese patients. These findings further advance the global development of iza-bren in EGFR-mutated NSCLC and build upon the clinical activity reported across multiple tumor types at prior international medical meetings. "The data being presented at WCLC provide important insights into the clinical profile of iza-bren in global patients with previously treated EGFR-mutated metastatic NSCLC," said Jonathan Cheng, M.D., Chief Medical Officer of SystImmune. "We are encouraged by the promising antitumor activity observed in this randomized dose-expansion cohort, including the increased efficacy observed at the 2.5 mg/kg dose level. Together with the safety and pharmacokinetic findings, these results support 2.5 mg/kg D1D8 Q3W as the recommended Phase 3 dose and represent an important step forward as we advance the global registrational study, IZABRIGHT-Lung01, in patients with EGFR-mutated NSCLC following progression on a third-generation EGFR inhibitor."

News and Publications > SystImmune Reports Phase 1 Data for BL-M14D1 Demonstrating Promising Activity in Small-Cell Lung Cancer at ASCO SystImmune Reports Phase 1 Data for BL-M14D1 Demonstrating Promising Activity in Small-Cell Lung Cancer at ASCO June 1st, 2026 Redmond, Washington June 1, 2026 Redmond, WA - Jun 1, 2026 - SystImmune, Inc., a clinical-stage biotechnology company, today announced the oral presentation of Phase 1 data for BL-M14D1 in patients with small-cell lung cancer (SCLC), neuroendocrine carcinoma (NEC), and other solid tumors (BL-M14D1-101, NCT06505824) at the American Society of Clinical Oncology (ASCO) 2026 Annual Meeting in Chicago. BL-M14D1 is a DLL3 targeting antibody drug conjugate being developed globally by SystImmune, a subsidiary of Biokin. This study evaluated the safety and efficacy of BL-M14D1 in Chinese patients with advanced SCLC, NEC, and other solid tumors. As of the November 30, 2025 data cut-off, BL-M14D1 demonstrated: - Promising antitumor activity in heavily pre-treated patients across multiple tumor types, including SCLC and other NECs - Manageable safety profile, with hematologic adverse events managed with standard supportive care A total of 127 patients with advanced solid tumors were treated, including 87 with SCLC and 40 with NEC. Most patients were heavily pre-treated. The most common adverse events were hematologic, including neutropenia, which were generally manageable and infrequently led to dose reductions or serious complications. The safety profile is consistent with other brengitecan based topo1 ADCs. One case of grade 3 interstitial lung disease was seen, and one treatment related death was reported. Among patients with SCLC treated at 4.0 mg/kg D1Q3W, the confirmed objective response rate was 62% (21 of 34 patients), with a median progression-free survival of 7.2 months. Based on these results, SystImmune plans to initiate a global registrational study in first-line extensive-stage SCLC. "These initial Phase 1 results for BL-M14D1 demonstrate compelling anti-tumor activity, including a 62% confirmed response rate and encouraging durability, in heavily pre-treated patients with small-cell lung cancer," said Jonathan Cheng, M.D., Chief Medical Officer of SystImmune. "Given the significant unmet need in this population, we believe these data support the potential for BL-M14D1 to become an important new treatment option, and we are rapidly advancing the program into global registrational studies in the first-line setting." About the BL-M14D1-101 Phase I clinical trial BL-M14D1-101 (NCT06505824) is a multi-center, Phase I study to evaluate the safety, tolerability, pharmacokinetic characteristics and preliminary efficacy of BL-M14D1 in locally advanced or metastatic solid tumors. The study is being conducted in three parts (dose escalation, dose finding, and dose expansion) with patients being dosed on Day 1 of a continuous 21-day treatment cycle (D1Q3W). In the dose escalation and dose expansion phase, patients were treated with BL-M14D1 at 0.66, 2.0, 3.5, 4.0, 4.5, 5.0, and 6.0 mg/kg. In the dose expansion phase, SCLC and NEC patients were treated at 4.0 and 4.5mg/kg D1Q3W. The primary endpoint includes safety. Secondary endpoints include objective response rate (ORR) by RECIST 1.1 criteria, duration of response (DoR), disease control rate (DCR), and PK analysis. About BL-M14D1 SystImmune is advancing a portfolio of next-generation antibody-drug conjugates (ADCs) built on its proprietary brengitecan platform, which utilizes a potent topoisomerase I inhibitor payload designed for targeted delivery to tumor cells. The clinical progress of izalontamab brengitecan (iza-bren) provides initial validation of this platform's potential to deliver meaningful anti-tumor activity across multiple cancer types. BL-M14D1 targets DLL3, which is highly expressed in small-cell lung cancer and neuroendocrine tumors, facilitating selective delivery of the brengitecan payload to DLL3-positive tumor cells.
