Details and patient eligibility

About

This is a multicenter, open-label, 2-arm study comparing erlotinib exposure in cancer patients with adequate hepatic function versus cancer patients with moderate hepatic impairment. All patients will receive a single 150 mg dose of erlotinib on Day 1 followed by 96 hours of plasma sampling for PK and protein binding studies. Patients may then enter the maintenance phase of the study and continue to receive erlotinib until disease progression or unacceptable toxicity.

Inclusion criteria

Histologically confirmed advanced solid tumor (measurable or nonmeasurable) that is potentially responsive to erlotinib or for which no effective therapy is available,
Cohort 1: Adequate hepatic function: bilirubin <= ULN, ALT (SGPT) and AST (SGOT) <= 1.5 x ULN or Cohort 2: Moderate hepatic function: 7-9 as assessed by the Child-Pugh System, ECOG Performance Status 0-2
Life expectancy >= 12 weeks,
Prior radiation permitted provided that 4 weeks (or 2 weeks for palliative radiation) has elapsed and patients have recovered from acute toxic effects of radiotherapy,
Prior chemotherapy permitted provided that 4 weeks has elapsed and patients have recovered from acute toxic effects of chemotherapy,
Adequate hematopoietic and renal function: ANC >= 1.5 x 10^9/L, platelets >= 75 x 10^9/L, and creatinine <= 1.5 x ULN,

Exclusion criteria

Use of tobacco or nicotine-containing products within 4 weeks of Day 1 and while on study,
Use of a CYP3A4 inhibitor or inducer within 14 days prior to Day 1 and until Day 5,
Use of a warfarin-derivative anticoagulant within 14 days prior to Day 1 and until Day 5,
Encephalopathy >= grade 2,
Significant history of cardiac disease unless well-controlled,
Active or uncontrolled infections or serious illnesses or medical conditions that could interfere with the patient's ongoing participation,
Concurrent anticancer therapy or any other investigational agents within 4 weeks of Day 1 and while on study,
Symptomatic brain metastases that are not stable, require steroids, are potentially life-threatening, or that have required radiation within the last 4 weeks,
Gastro-intestinal abnormalities, including inability to take oral medication, requirement for IV alimentation, active peptic ulcer or prior surgical procedures affecting absorption.
