Lapatinib and Temozolomide for the Treatment of Progressive Brain Disease in HER-2 Positive Breast Cancer

Phase 1 Study of the Combination of Lapatinib and Temozolomide for the Treatment of Progressive Brain Disease in HER-2 Positive Breast Cancer

• Status: Completed
• Phase: Phase 1
• Study type: Interventional
• Enrollment: 18 (actual)
• Sponsor: Jules Bordet Institute · Academic / Other
• Sex: Female
• Age: 18 Years – 70 Years
• Healthy volunteers: Not accepted

Summary

Objectives: Primary - Determine the maximum tolerated dose (MTD) and evaluate the dose limiting toxicities (DLT) of combining lapatinib and temozolomideSecondary - Obtain preliminary information on the clinical anti-tumor activity of lapatinib plus temozolomide on brain metastases secondary to HER-2 positive breast cancer including Objective Response Rate (ORR), Clinical Benefit (CB) and Duration of Response (DR) Methodology: Phase I, single-centre, open-label, dose-escalation study of combining lapatinib and temozolomide in HER-2 positive breast cancer patients with progressive brain metastases after surgery or radiotherapy or radiosurgery Treatment: Temozolomide will be given orally for 5 days of every 28 days, at doses of either 100mg/m2/day or 150mg/m2/day or 200mg/m2/day AND Lapatinib will be given orally every day at either 1000mg/day or 1250mg/day or 1500mg/day.Sequential cohorts will be escalated in increments according to the dose escalation scheme, and determined by dose limiting toxicities.

Detailed description

Patients selection criteria: * age 18 - 70 years * Women with cytologically or histologically proven metastatic breast cancer with recurrent / progressive brain metastases evaluable by MRI, after standard treatment with surgery (at least 3 weeks prior) or WBRT (at least 3 weeks prior) or stereotactic RT (at least 1 week prior); or otherwise deemed as unsuitable for standard treatment in the first instance * Known HER-2 positive status (immunohistochemistry (IHC) 3+ Fluorescence In Situ Hybridization (FISH) positive ) * Previous chemotherapy (adjuvant and metastatic regimens) allowed * Previous treatment with trastuzumab allowed (Trastuzumab to be discontinued prior to study entry) * At least one measurable lesion in the brain, defined as any lesion \>5mm in longest dimension on T1-weighted, gadolinium-enhanced MRI * Expected life-expectancy of more than 3 months * ECOG performance status of 0, 1 or 2 * Adequate bone marrow, renal and hepatic functionsLVEF * LVEF 50% measured by echocardiography or MUGA scan * Concomitant corticosteroids and anti-convulsants for symptomatic brain metastases are allowed
