Patient case: 45-year-old female with colon cancer; genetic feature: PIK3CA (E545K)

Clinical trial: A Study of WXFL10030390 in Patients With Advanced Solid Tumors or Lymphoma

Summary: WXFL10030390 (WX390) is a novel oral small molecular that inhibits phosphoinositide-3 kinase (PI3K) and mammalian target of rapamycin (mTOR) and has demonstrated potent inhibitory effects on multiple human tumor xenografts. The first-in-human study is conducted to assess the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT), to evaluate the pharmacokinetics, safety and preliminary anti-tumor activity of WX390 at single dose and multiple doses.

Detailed description: This study will be an open-lable, phase Ⅰ study and will evaluate the safety and pharmacokinetics of WX390 after a single administration followed by a 28-day continuous course of therapy; evaluate the safety and preliminary efficacy in an open-lable administration of WX390 at the MTD.
