Trial overview
Official title: A Four-Way Cross-Over Study to Examine the Effects of Lapatinib on the Pharmacokinetics of Orally and Intravenously Administered Midazolam in Cancer Patients
Trial description: To characterize the effect of repeat oral dose of lapatinib treatment on the pharmacokinetics of a single oral and single intravenous dose of midazolam in adult cancer patients. Also to assess the safety and tolerability of chronic oral lapatinib therapy in cancer patients.

Maximum observed concentration (Cmax) of midazolam
Timeframe: Pre-dose, 2 minutes, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 10 and 24 hours post-dose on Day 1, Day 3, Day 9 and Day 11
Clearance (CL) of midazolam
Timeframe: Pre-dose, 2 minutes, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 10 and 24 hours post-dose on Day 1, Day 3, Day 9 and Day 11
Half-life (t½) of midazolam
Timeframe: Pre-dose, 2 minutes, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 10 and 24 hours post-dose on Day 1, Day 3, Day 9 and Day 11
Absolute bioavailability (F) of midazolam
Timeframe: Pre-dose, 2 minutes, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 10 and 24 hours post-dose on Day 1, Day 3, Day 9 and Day 11
Secondary outcomes:
Time of maximum observed concentration (tmax) of midazolam
Timeframe: Pre-dose, 2 minutes, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 10 and 24 hours post-dose on Day 1, Day 3, Day 9 and Day 11
Volume of distribution (Vss) of midazolam
Timeframe: Pre-dose, 2 minutes, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 10 and 24 hours post-dose on Day 1, Day 3, Day 9 and Day 11

Inclusion and exclusion criteria
Inclusion criteria:

- Tumor for which there is no standard therapy.
- Able to swallow and retain oral medication.
- ECOG (Eastern Cooperative Oncology Group) performance status 0 to 2.
- Provided written informed consent.

- Aspartate and alanine transaminase is less than or equal to 3 times the upper limit of the institutional values.
- Have a left ventricular ejection fraction (LVEF) greater than or equal to 40% based on electrocardiogram (ECHO) or multiple gated acquisition scan (MUGA).
- Resting oxygen saturations of greater than 90%.
Exclusion criteria:
- Pregnant or lactating female.
- Have malabsorption syndrome, a disease affecting gastrointestinal function.
- Resection of the stomach or small bowel.
- Evidence of symptomatic or uncontrolled brain metastases or leptomeningeal disease.
- Is considered medically unfit for the study by the investigator as a result of the medical interview, physical exam, or screening investigations.
- Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to the investigational product.
