Official Title: “Phase I Study to Evaluate the Effect of Ketoconazole on the Pharmacokinetics of Dasatinib and the Effect of Dasatinib on Pharmacodynamic Markers in Patients With Advanced Solid Tumors”

The purpose of Segment 1 of the study is to determine the effect of ketoconazole on dasatinib. The purpose of Segment 2 is to learn how dasatinib affects tumor growth in patients with advanced solid tumors.

Study Type: Interventional

Study Design: Treatment, Non-Randomized, Open Label, Uncontrolled, Parallel Assignment, Pharmacokinetics/Dynamics Study

Intervention(s) in this Clinical Trial

• Drug: Dasatinib + Ketoconazole
  • Tablets, Oral, Segment 1: escalating single dose of dasatinib starting at 140 mg q24 hours on Day 1-8; single dose of ketoconazole 200 mg q12 hours on Days 3-8; Segment 2: single daily oral doses of dasatinib, once daily, until disease progression or unacceptable toxicity.

Arms, Groups and Cohorts in this Clinical Trial

• Active Comparator: 1

Primary Measures

• Segment 1: Determine whether the steady state pharmacokinetics of 20 mg of dasatinib are affected by co-administration with ketoconazole in patients with advanced solid tumors
• Segment 2: Assess the pharmacodynamic activity of dasatinib

Secondary Measures

• Segment 1: Evaluate the safety and tolerability of dasatinib alone and when co-administered with ketoconazole
• Segment 2: Explore the association between tumor response and the pre-clinically identified markers and other mRNA gene expression level

Inclusion Criteria:
