LY573636-sodium (tasisulam) is a small molecule antitumor agent with a novel mechanism of action currently being investigated in a variety of human cancers. In vitro, tasisulam induced apoptosis via the intrinsic pathway, resulting in cytochrome c release and caspase-dependent cell death. Using high content cellular imaging and subpopulation analysis of a wide range of in vitro and in vivo cancer models, tasisulam increased the proportion of cells with 4N DNA content and phospho-histone H3 expression, leading to G(2)-M accumulation and subsequent apoptosis. Tasisulam also blocked VEGF, epidermal growth factor, and fibroblast growth factor-induced endothelial cell cord formation but did not block acute growth factor receptor signaling (unlike sunitinib, which blocks VEGF-driven angiogenesis at the receptor kinase level) or induce apoptosis in primary endothelial cells. Importantly, in vivo phenocopying of in vitro effects were observed in multiple human tumor xenografts.
2.A phase I study of tasisulam sodium using an albumin-tailored dose in Japanese patients with advanced solid tumors.

PURPOSE: This phase I study was designed to determine the maximum tolerated dose (MTD) and the dose to be recommended for a future phase II study of tasisulam sodium in Japanese patients with advanced, refractory solid tumors. Safety, pharmacokinetics and preliminary anti-tumor activities were assessed. Due to high-affinity albumin binding, an albumin-tailored dose to reduce the variability in tasisulam exposure was also studied.

PURPOSE: This phase I study was carried out to determine the phase II recommended dose of tasisulam sodium (hereafter, tasisulam), a novel anticancer agent with a unique mechanism of action.

BACKGROUND: Tasisulam sodium (hereafter referred to as tasisulam) is a novel, highly albumin-bound agent that demonstrated activity in a phase 2 melanoma study.
