Phase I first-in-human study of CUDC-101, a multitargeted inhibitor of HDACs, EGFR, and HER2 in patients with advanced solid tumors.

Purpose: This first-in-human phase I study evaluated dose-limiting toxicities (DLT) and defined a phase II recommended dose (RD) for CUDC-101, a multitargeted inhibitor of HDACs, EGFR, and HER2 as a 1-hour intravenous (i.v.) infusion for 5 consecutive days every 2 weeks.

The clinical effect of the dual-targeting strategy involving PI3K/AKT/mTOR and RAS/MEK/ERK pathways in patients with advanced cancer.

Purpose: This study evaluated the clinical relevance of the dual-targeting strategy involving PI3K/AKT/mTOR and RAF/MEK/ERK pathways.

Experimental Design: We investigated safety, efficacy, and correlations between tumor genetic alterations and clinical benefit in 236 patients with advanced cancers treated with phase I study drugs targeting phosphoinositide 3-kinase (PI3K) and/or mitogen-activated protein kinase (MAPK) pathways in our Phase I Clinical Trials Program.

Results: Seventy-six (32.
