Preliminary biomarker and pharmacodynamic data from a phase I study of single-agent bispecific antibody T-cell engager GBR 1302 in subjects with HER2…

69 Background: HER2 is overexpressed in many solid tumors and is a validated therapeutic target. GBR 1302 is a HER2xCD3 bispecific antibody engineered (using Glenmark’s BEAT® platform) to direct T-cells to HER2-expressing tumor cells. GBR1302-101 (NCT02829372) is an ongoing, multicenter, open-label, first-in-human study of GBR 1302 in subjects with HER2-positive cancers to evaluate the safety, tolerability, and preliminary efficacy of GBR 1302, and to elucidate the mechanism(s) by which it redirects T-cells to tumor and enhances cytolytic activity of cytotoxic T-cells. Methods: Adults with progressive HER2-positive solid tumors with no available standard or curative treatment receive intra…
A phase I study of the bispecific antibody T-cell engager GBR 1302 in subjects with HER2-positive cancers.
2017
TPS3091 Background: GBR 1302, a bispecific antibody based on Glenmark’s BEAT platform, is designed to recruit cytotoxic T-cells (independent of their specificity) to HER2-positive cancer cells where they are activated by the CD3e-specific domain of the molecule. Preclinically, GBR 1302 has demonstrated potent killing of HER2-positive human cancer cells (HER2 3+ or 2+ by IHC HercepTest), as well as growth suppression of the trastuzumab-resistant cell line JIMT-1. In contrast, the GBR 1302 concentration required to kill primary cardiomyocytes with normal HER2 levels was up to 1000 times greater than the concentration needed to kill HER2 3+ tumor cell lines. This study will determine safety a…

Abstract The MASTER (Molecularly Aided Stratification for Tumor Eradication Research) Program of the NCT (National Center for Tumor Diseases) Heidelberg and the DKTK (German Cancer Consortium) is situated at the interface of cancer genomics and clinical oncology to provide whole exome/genome and transcriptome sequencing to selected patients with unmet medical need, and to evaluate the utility of such an approach regarding molecular stratification and individualized, biology-guided treatment. The program has enabled implementation of a shared, DKTK-wide workflow for rapid-turnaround clinical sequencing, comprising all steps from sample processing to reporting of results by a dedicated molecu…
A phase I, open-label, dose-escalation trial of BI 764532, a DLL3/CD3 bispecific antibody, in patients (pts) with small cell lung carcinoma (SCLC) or…
2021
TPS8588 Background: First-line standard of care for pts with metastatic SCLC and neuroendocrine carcinoma (NEC) is platinum-based chemotherapy ± immunotherapy. While the addition of anti-PD1 antibodies has improved outcomes, nearly all pts relapse and prognosis is poor. There is a major unmet need for additional treatment (tx) options. BI 764532 is a delta-like ligand 3 (DLL3)/CD3 T cell engaging bispecific antibody. DLL3 is expressed on the cell surface of many SCLC and NEC tumors, but not on normal cells. In preclinical studies, BI 764532 induced cytotoxicity of DLL3-positive cells and showed anti-tumor activity in animal models. Methods: NCT04429087 is a first-in-human, open-label, dose…
Efficacy of Immune Checkpoint Inhibitors Alone or in Combination With Chemotherapy in NSCLC Harboring ERBB2 Mutations
2021
Abstract Introduction In contrast to other driver mutations, no targeted therapies have yet been approved in ERBB2-mutated NSCLC (HER2mu NSCLC). Nevertheless, several compounds have revealed promising early efficacy data, which need to be evaluated in the context of current standard approaches. Although data on the efficacy of immune checkpoint inhibitors (ICIs) in second or subsequent lines of treatment remain limited and conflicting, there are virtually no data on patient outcome under ICI/platinum-doublet combinations in the first-line setting. Methods We retrospectively evaluated outcomes of patients with HER2mu NSCLC treated with ICI alone or in combination with chemotherapy within the…
