An enhancement in inhibition of tumor growth and suppression of c-MYC expression was further confirmed when enzalutamide combined with KRLS-017 in an MDA-MB-453 mouse model. Our study suggests that KRLS-017 enhances the antitumor efficacy of enzalutamide by inhibiting c-MYC-mediated tumorigenesis and presents a potential new approach for treating AR+ LAR TNBC.
Our results suggest that enzalutamide synergizes with UD-017 by inhibiting c- MYC–mediated oncogenic activity. These in vitro data warrant future in vivo studies of the antitumor synergy of enzalutamide plus UD-017 in AR+ LAR TNBC models.
