Deruxtecan analog is a drug-linker conjugate for antibody-drug conjugate (ADC). Deruxtecan, a topoisomerase I inhibitor, is an exatecan derivative (DX-8951 derivative) with a cleavable pepetide linker and a maleimide group. The maleimide group in Deruxtecan can react with antibody to form antibody-drug conguates (ADC) such as Trastuzumab deruxtecan (DS-8201a), which is a HER2-targeting antibody-drug conjugate. DS-8201a significantly suppressed tumor growth in an immunocompetent mouse model with human HER2-expressing CT26.WT (CT26.WThHER2) cells. DS-8201a is currently in clinical trials.

1.[fam-] trastuzumab deruxtecan, antitumor activity is dependent on HER2 expression level rather than on HER2 amplification

Therapies targeted to human epidermal growth factor receptor 2 (HER2) have proven effective against tumors positive for HER2 amplification, but there is an unmet clinical need for the treatment of tumors that express HER2 protein in the absence of HER2 amplification. [fam-] trastuzumab deruxtecan (DS-8201a) is a novel antibody-drug conjugate composed of the anti-HER2 antibody and the topoisomerase I inhibitor, an exatecan derivative. It has shown efficacy against tumors that express HER2 and is currently under evaluation in clinical trials. We here show that the antitumor activity of [fam-] trastuzumab deruxtecan is dependent on the expression level of HER2 protein in colorectal cancer (CRC) cell lines negative for HER2 amplification. We established isogenic CRC cell lines that express various levels of HER2 protein in the absence of HER2 amplification, and we found that cells that express HER2 at a high level were sensitive to [fam-] trastuzumab deruxtecan but not to conventional HER2-targeted therapies. Furthermore, [fam-] trastuzumab deruxtecan manifested a bystander killing effect both in vitro and in vivo, with cells essentially negative for HER2 expression also being killed in the presence of HER2-expressing cells, an effect that has the potential to overcome heterogeneity of HER2 expression in CRC tumors. Our results thus suggest that [fam-] trastuzumab deruxtecan warrants further study as a potential treatment for CRC tumors that express HER2 protein in the absence of HER2 amplification.
2.HER2 Directed Antibody-Drug-Conjugates beyond T-DM1 in Breast Cancer
Rinnerthaler G, Gampenrieder SP, Greil R
Since the discovery of the human epidermal growth factor receptor 2 (HER2) as an oncogenic driver in a subset of breast cancers and the development of HER2 directed therapies, the prognosis of HER2 amplified breast cancers has improved meaningfully. Next to monoclonal anti-HER2 antibodies and tyrosine kinase inhibitors, the antibody-drug conjugate T-DM1 is a pillar of targeted treatment of advanced HER2-positive breast cancers. Currently, several HER2 directed antibody-drug conjugates are under clinical investigation for HER2 amplified but also HER2 expressing but not amplified breast tumors. In this article, we review the current preclinical and clinical evidence of the investigational drugs A166, ALT-P7, ARX788, DHES0815A, DS-8201a, RC48, SYD985, MEDI4276 and XMT-1522.
3.Trastuzumab deruxtecan (DS-8201a) in patients with advanced HER2-positive gastric cancer: a dose-expansion, phase 1 study

BACKGROUND:Trastuzumab deruxtecan (DS-8201a) is a novel HER2-targeted antibody-drug conjugate with a humanised anti-HER2 antibody, cleavable peptide-based linker, and topoisomerase I inhibitor payload. A phase 1, non-randomised, open-label, multiple-dose study was done to assess the safety, tolerability, and activity of trastuzumab deruxtecan in HER2-expressing advanced solid tumours. The dose escalation (part 1) has previously been reported and the recommended doses for expansion of 5·4 mg/kg or 6·4 mg/kg were established. In this Article, we report the safety and preliminary activity results from this phase 1 trial in all patients with HER2-positive gastric or gastro-oesophageal junction cancer who received trastuzumab deruxtecan at the recommended doses for expansion.
