Exploratory subgroup analysis of patients with prior trastuzumab use in the ATTRACTION-2 trial: a randomized phase III clinical trial investigating the efficacy and safety of nivolumab in patients with advanced gastric/gastroesophageal junction cancer

ConclusionsNivolumab was efficacious and safe as third- or later-line therapy regardless of prior trastuzumab use in patients with advanced G/GEJ cancer.

In this study, we developed a novel anti-HER2 monoclonal antibody (mAb), H2Mab-41 (IgG2b, kappa), and the antitumor activity of H2Mab-41 was investigated using mouse xenograft models. Caco-2 cells (human colon cancer cell line), which expresses HER2, were subcutaneously implanted into the flanks of nude mice. H2Mab-41 and control mouse IgG were injected three times into the peritoneal cavity of mice. H2Mab-41 significantly reduced tumor development of Caco-2 xenograft in comparison with the control mouse IgG on days 5, 8, 11, 15, and 19. Taken together, these results suggest that H2Mab-41 is useful for antibody therapy aga...

Authors: Al Diffalha S, Sexton KC, Watson PH, Grizzle WE Abstract Medical research advances enabling the realization of precision medicine have relied heavily on the biospecimens provided by bioresources to identify the targets and biomarkers that are the focus of the new generation of more effective molecular-based therapies for specific subtypes of diseases. Through the biospecimens they have distributed, bioresources have permitted subtypes of cancers to be identified and molecular features of these subtypes to be effectively targeted. A prototype example is the human epidermal growth factor receptor type 2 (HER...

ConclusionIn our analysis, pathological staging and primary site were main prognostic factors. Moreover, a small group of EGJ/HER2+ had very poor survival.

ConclusionsPertuzumab exposure in JACOB was consistent with prior studies in advanced gastric cancer and breast cancer. The 840  mg q3w dose allowed the majority of patients in JACOB to achieve target pertuzumab concentrations and appears to be an appropriate dose selection.

Purpose of review This manuscript aims at providing an update and overview on the role of Human epidermal growth factor receptor 2 (HER2) testing and HER2-directed therapies in digestive tumors. Recent findings Phase 3 trial data demonstrating a survival benefit of HER2-targeting treatments are limited to gastric cancer. However, HER2 positivity is also found in 5–6% of colorectal, 7% of pancreatic, and 16% of extrahepatic biliary cancers. Although phase 2 trial data support the use of the combination of trastuzumab and lapatinib with chemotherapy in HER2-positive colorectal cancer, the patient's benefit from ta...

HER2, a member of the epidermal growth factor receptor (EGFR) family, has been associated with human breast, ovarian and gastric cancers. Anti-HER2 monoclonal antibodies (mAbs) have demonstrated clinical efficacy for HER2-overexpressing breast cancer. A chimeric antibody chA21 that specifically inhibits the growth of HER2-overexpressing cancer cells both in vitro and in vivo has previously been developed. To reduce a potential human anti-mouse immune response, the humanized antibody HuA21 was developed and was further subjected to affinity maturation by phage display on the basis of chA21. Here, the crystal structure of Hu...

604Objectives: The purpose of this study was to develop a HER2-targeted affibody 68Ga-NOTA-MAL-MZHER2 and confirmed the possibility of clinical transformation. A pilot study including six patients was enrolled. We measured the safety, bio-distribution of 68Ga-NOTA-MAL-MZHER2 in clinical PET study. What’s more, we determine whether bone metastases from HER2-positive gastric cancer could be detected noninvasively by using 68Ga-NOTA-MAL-MZHER2 PET imaging and using 18F-FDG as a control. Methods: 68Ga-NOTA-MAL-MZHER2 was produced under current Good Manufacturing Practices (cGMP) conditions. Quality control was conducted ...
