A Cardiac Safety Study of Tivozanib to Evaluate the Electrocardiogram and Pharmacokinetic-Electrocardiogram Dynamics in Subjects With Advanced Solid Tumors

An Open-Label Cardiac Safety Study of Tivozanib to Evaluate the Electrocardiogram and Pharmacokinetic-Electrocardiogram Dynamics in Subjects With Advanced Solid Tumors

The purpose of this study is to obtain QTc data, to assess the effects of tivozanib on ECG morphology, and to determine the pharmacokinetic pharmacodynamic (PK-PD) relationship between any observed changes in cardiac repolarization (defined by QTcF duration) and the serum concentration of tivozanib.

Study Overview

• Status: Completed
• Conditions: Advanced Solid Tumors
• Intervention / Treatment: Drug: tivozanib

Detailed Description

Tivozanib is a novel and potent pan-vascular endothelial growth factor (VEGF) receptor (VEGFR) tyrosine kinase inhibitor with potent activity against all 3 VEGFRs (VEGFR-1, -2, and -3). In nonclinical models and studies performed in humans, tivozanib has shown strong antiangiogenesis and antitumor activity.

This study is an open-label, non-randomized, exploratory single-arm trial evaluating the ECG and pharmacokinetic (PK)-ECG relationship, if any, of tivozanib in subjects with advanced solid tumors.

The purpose of this study is to evaluate the ECG intervals and morphology following treatment with tivozanib in subjects with advanced solid tumors and to determine the relationship, if any, of the change in QTc duration with serum concentration of tivozanib over time in subjects with advanced solid tumors.

  • hemoglobin < 9.0 g/dL;

  • Absolute neutrophil count < 1500 per mm3;

  • platelet count < 100,000 per mm3;

• Any of the following serum chemistry or urine abnormalities:

  • total bilirubin > 1.5 × ULN (or > 2.5 × ULN for subjects with Gilbert's syndrome);

  • AST or ALT > 2.5 × ULN (or > 5 × ULN for subjects with liver metastasis);
  • alkaline phosphatase > 2.5 × ULN (or > 5 × ULN for subjects with liver or bone metastasis);
  • creatinine > 2.0 × ULN;
  • proteinuria > 3+ by urinalysis;

• Serious/active infection or infection requiring parenteral antibiotics or antifungal therapy;
• Inadequate recovery from any prior surgical procedure or major surgical procedure within 4 weeks prior to administration of first dose of study drug;
