LDE225 in Patients With Advanced or Metastatic Hepatocellular Carcinoma and Child-Pugh A/B7 Cirrhosis

Phase 1

Completed

• Conditions: Hepatocellular Carcinoma; Cirrhosis
• Interventions: Drug: LDE225

• Registration Number: NCT02151864
• Lead Sponsor: Jason K. Sicklick, M.D.

Brief Summary

The purpose of this study is to test the safety and determine the maximum safe dose of an experimental drug called LDE225 (hedgehog inhibitor) in people with liver cancer. We have identified hedgehog dysregulation as a novel mechanism for hepatocarcinogenesis and hepatic fibrosis/cirrhosis. Therefore, we hypothesize that the hedgehog inhibitor may be an ideal drug target for treating both hepatocellular carcinoma (HCC) and Child-Pugh A cirrhosis (CPA).

Detailed Description

This is an open-label, single institution, Phase I, 3+3 dose escalation study of LDE225 in patients with advanced or metastatic hepatocellular carcinoma and Child-Pugh A Cirrhosis who are intolerant to sorafenib. The investigational treatment cycle (21 days) will consist of daily oral LDE225.

Dose escalation will be performed in serial patient cohorts. Up to six patients can be studied at each dose level. Safety and clinical data will be tabulated and the decision to open the next cohort level will be the responsibility of the principal investigator. Dose escalation will be based on the dose-limiting toxicities encountered through Day 42 of investigational treatment.

Patients will be dosed on a flat scale of daily dosing of LDE225 prescribed by the dose cohort.

Primary Outcome Measures

Name	Time	Method
