The impact of HER3 dynamics on the efficacy of HER3-DXd, a novel HER3 directed antibody-drug conjugate (Section 19; Poster Board #19) - Mar 14, 2023 - Abstract #AACR2023AACR_6070; HER3 expression was dynamically changed by HER3-DXd dosing regimen and by RTKi treatment, resulting in a substantial impact on payload release. These findings support our strategy of clinical studies using HER3-DXd after drugs that increase HER3 expression including EGFR TKI and indicate that HER3 dynamics may play a key role in achieving optimal efficacy of HER3-DXd.

Review, Journal: Antibody-drug conjugates in lung cancer: dawn of a new era? (Pubmed Central) - Jan 12, 2023 In this review, we discuss the structure and mechanism of action of ADCs, including insights from pre-clinical work; we summarize the ADCs' recent progress in lung cancer, describe toxicity profiles of ADCs, and explore strategies designed to enhance ADC potency and overcome resistance. In addition, we discuss novel ADC strategies of interest in lung cancer, including non-cytotoxic payloads, such as immunomodulatory and anti-apoptotic agents.

Review, Journal, IO biomarker: New Strategies and Novel Combinations in EGFR TKI-Resistant Non-small Cell Lung Cancer. (Pubmed Central) - Oct 28, 2022 In this review, we outline our proposed approach to current clinical practice for patients with EGFR mutant, osimertinib-resistant NSCLC which includes the following potential strategies: - Continuation of osimertinib beyond progression following local ablative treatment of oligoprogressive disease, - Tissue rebiopsy of progressive site and possibly concurrent liquid biopsy to evaluate for mechanism of resistance utilizing comprehensive genomic profiling, -Discussion at a molecular tumor board for assessment for enrollment in clinical trials/expanded access program if available with innovative drugs or possible off-label use of available targeted agents, based on the results of molecular profiling, -If no mechanism of resistance identified, administration of platinum-based chemotherapy with antiangiogenic agents. The role of immunotherapy will also be addressed given the uncertain benefit.

Next-generation sequencing: We’re in the ADC era! Saci, T-DXd, and soon Dato-DXd, HER3-DXd… and then, who knows, NGS may open the door to chemo-free approaches… TMB-high is not uncommon in MBC, as shown by @DrRBarroso among others, and can predict response to IO even in late lines!
