MT-4561 / Tanabe Pharma - LARVOL DELTA

A novel BRD4 degrader, MT-4561, degrades the BRD4-NUT fusion protein in vitro and induces complete tumor regression in a subcutaneous NUT carcinoma xenograft model (AACR-NCI-EORTC 2025) - " In vitro studies: MT-4561 demonstrated potent antitumor activity against Ty-82 cells, a NUT carcinoma cell line harboring the BRD4-NUT fusion protein, and showed greater efficacy than the BET inhibitor JQ1. MT-4561 exhibited potent antitumor efficacy against NUT carcinoma in both in vitro and in vivo studies. Notably, MT-4561 demonstrated activity not only against BRD4-NUT cells but also against BRD3-NUT cell lines. This effect is considered to be mediated through suppression of c-MYC (expression)."
