The Importance of Human Tissue Bioresources in Advancing Biomedical Research.

The Importance of Human Tissue Bioresources in Advancing Biomedical Research. Biopreserv Biobank. 2019 Jun;17(3):209-212 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 (HER2), which currently is targeted in breast and gastric cancers. In the future, the use of biospecimens from bioresources will continue to increase the understanding of the molecular actions of drugs and how drugs may be more or less active in subpopulations of patients. Although the biospecimen inventories of the initial forms of bioresources may not have always been optimally planned and, therefore, utilized in supporting biomedical research, bioresources are evolving and overall, bioresource inventories and increasingly their prospective collection capabilities will continue to be a critical component of the research infrastructure.

However, a direct comparison between the results of HER2 immunohistochemistry (IHC) and next-generation sequencing (NGS)–based cancer panel tests has not been explored in GC. We aimed to determine optimal thresholds of HER2 overexpression to be detected by NGS with the data of 16...

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...

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.
