Phase II Trial of Lapatinib & Capecitabine for Patients With Refractory Advanced Colorectal Adenocarcinoma

• Status: Completed
• Trial end date: 2009-08-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to find out how effective this combination is as a second line treatment for colorectal cancer that has spread from one part of the body to another (metastasized) or has not metastasized but is considered inoperable (unable to be removed by surgery). The side effects and survival experienced by subjects receiving these drugs will also be evaluated. This is a phase II research study.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: University of Wisconsin, Madison
• Collaborator: GlaxoSmithKline
• Treatments: Capecitabine; Lapatinib

Criteria

Inclusion Criteria:

• Age > 18 years

• Pathologically confirmed, locally advanced or metastatic adenocarcinoma of the colon or rectum

• Patients must have had progression of disease on prior therapy with an oxaliplatin-containing or irinotecan containing regimen

• Proper radiographic documentation of measurable disease using RECIST criteria

• ECOG performance status (PS) of 0 or 1

• Laboratory parameters:

Hgb: ≥ 9.0 g/dl ANC ≥ 1500/ul Platelet ≥ 100,000/ul Creatinine ≤ 2x ULN OR Creatinine clearance ≥ 30 mg/ml Bilirubin ≤ 2x ULN AST ≤ 2x ULN or 5X ULN if liver metastases are present

• Patient has signed informed consent

• Toxicities from prior therapy (except alopecia and neuropathy) must have resolved to grade 1 or better prior to enrollment

Exclusion Criteria:

• Administration of more than one prior systemic chemotherapy for metastatic disease

• Pregnant or breast-feeding women: female patients must agree to use effective contraception, must be surgically sterile, or must be postmenopausal. Male patients must agree to use effective contraception or be surgically sterile. The definition of effective contraception will be based on the judgment of the principal investigator or a designated associate. All at-risk female patients must have a negative serum pregnancy test within 7 days prior to randomization.

• Active inflammatory bowel disease, significant bowel obstruction, or chronic diarrhea (grade 2).

• Known human immunodeficiency virus (HIV) positivity or acquired-immunodeficiency-syndrome (AIDS)-related illness.

• No previous or concurrent malignancy is allowed except for adequately treated basal cell or squamous cell skin cancer, in-situ cervical cancer, or other cancer for which the patient has been disease-free for 3 years.

• Known CNS metastases

• Prior therapy which specifically and directly targets the EGFR pathway

• Significant history of uncontrolled cardiovascular disease, defined as:

• History of uncontrolled or symptomatic angina

• History of arrhythmias requiring medications, or clinically significant, with the exception of asymptomatic atrial fibrillation requiring anticoagulation

• Myocardial infarction < 6 months prior to study entry

• Cerebrovascular accident <6 months prior to study entry

• Uncontrolled or symptomatic congestive heart failure

• Ejection fraction below the institutional normal limit

• Any other cardiac condition, which in the opinion of the treating physician, would make this protocol unreasonably hazardous for the patient
