A Phase 1b, open-label, dose-escalation trial of the delta-like ligand 3 (DLL3)/CD3 IgG-like T cell engager, BI 764532, in patients with DLL3-positive glioma (SNO 2023)
Key exclusion criteria: extracranial metastatic or leptomeningeal disease; previous treatment with DLL3-targeting therapies; prior treatment with bevacizumab/other anti-VEGF/anti-angiogenic treatment ≤6 months prior to first administration of BI 764532; persistent toxicity from previous treatments that has not resolved to ≤CTCAE Grade 1; diagnosis of immunodeficiency, or intake of immunosuppressive therapy ≤7 days prior to first administration of BI 764532. Primary endpoints: dose-limiting toxicities (DLTs) during the maximum tolerated dose evaluation period (escalation phase); DLTs during the entire treatment period (expansion phase). Other objectives include pharmacokinetics, pharmacodynamics, preliminary efficacy and evaluation of DLL3 as a potential biomarker.

Phase I, non-randomised, open-label, multi-centre dose escalation trial of BI 764532 (DLL3/CD3 IgG-like T cell engager [TcE]) + ezabenlimab (anti-PD-1 antibody) in patients (pts) with small cell lung cancer (SCLC) and other neuroendocrine carcinomas (NECs) expressing DLL3 (ESMO 2023)
In the dose escalation part, the primary endpoint is dose-limiting toxicity (DLT) occurrence in the MTD evaluation period; secondary endpoints include DLT occurrence in the on-treatment period, objective response and pharmacokinetics. Enrolment is ongoing.

Emerging therapies targeting the delta-like ligand 3 (DLL3) in small cell lung cancer. (PubMed, J Hematol Oncol)
First, we discuss the clinical experience with rovalpituzumab tesirine (Rova-T), a DLL3-targeting ADC, the development of which was halted due to a lack of efficacy in phase 3 studies, with a view to understanding the lessons that can be garnered for the rapidly evolving therapeutic landscape in SCLC. We then review preclinical and clinical data for several DLL3-targeting agents that are currently in development, including the TCE molecules-tarlatamab (formerly known as AMG 757), BI 764532, and HPN328-and the CAR T-cell therapy AMG 119. We conclude with a discussion of the future challenges and opportunities for DLL3-targeting therapies, including the utility of DLL3 as a biomarker for patient selection and disease progression, and the potential of rational combinatorial approaches that can enhance efficacy.

First-in-human dose-escalation trial of BI 764532, a delta-like ligand 3 (DLL3)/CD3 IgG-like T-cell engager in patients (pts) with DLL3-positive (DLL3+) small-cell lung cancer (SCLC) and neuroendocrine carcinoma (NEC). (ASCO 2023)
BI 764532 showed clinically manageable tolerability and MTD has not been reached at the doses administered to date. Promising efficacy has been observed, not only in SCLC but also in difficult to treat entities such as NEC and LCNEC. The study is ongoing; updated data will be presented.

Phase I trial of the DLL3/CD3 bispecific T-cell engager BI 764532 in DLL3-positive small-cell lung cancer and neuroendocrine carcinomas. (PubMed, Future Oncol)
Here, we describe the study design of a first-in-human, phase I, multicenter, open-label, non-randomized, dose-escalation study in patients with SCLC or other DLL3-positive neuroendocrine carcinomas. The study will determine the maximum tolerated dose and evaluate safety, tolerability, pharmacokinetics and preliminary efficacy of BI 764532 monotherapy.
