Brief Title: Randomized RT +/- Lapatinib for Advanced Solid Tumor Cancer Patients Receiving Radiation Therapy for Metastatic Disease
Official Title: A Randomized Study of Lapatinib With Radiation Versus Radiation Alone in Advanced Solid Tumor Cancer Patients Receiving Radiation Therapy for Metastatic Disease
Study ID: NCT01427322
Brief Summary: Lapatinib will prevent radiation-induced increase in Transforming Growth Factor alpha (TGFα), an important growth factor in cancer cell recovery after ionizing irradiation.
Detailed Description: Lapatinib is an orally bioavailable small molecule inhibitor of ERBB1 and ERBB2 (HER2). It is currently indicated for use in patients with HER2 over-expressing metastatic breast cancer. Serum increases in TGFα can have growth potentiating effects on distant sites of metastatic disease. Palliative irradiation paradoxically may promote distant tumor growth; blocking shedding of TGFα from irradiated tumors may prevent this effect and improve the therapeutic index of radiation therapy.
