Summary

In spite of the use of radiation combined with conventional chemotherapy, the long-term survival prognosis for most patients with locally advanced non-small cell lung cancer is disappointing. Much effort is currently focussed on exploring new molecular targeted agents that may improve upon survival. The addition of an agent that targets blood vessel formation in tumors, bevacizumab or Avastin, to conventional chemotherapy has been shown to improve survival in metastatic non-small cell lung cancer. Data from animal studies have shown that bevacizumab and related agents also increase tumor cure rates when administered both during and after radiotherapy. This suggests that combined bevacizumab and chemo-radiation may improve survival in local-advanced disease as well. Before such clinical studies can commence, the safety and normal tissue toxicity profile of bevacizumab with thoracic radiotherapy must first be established. In this study, escalating doses of bevacizumab will be administered during radiotherapy, followed by maintenance bevacizumab.

Clinical Details

Official title: Phase I Study of Concurrent Bevacizumab (Avastin) With Involved-field Thoracic Radiotherapy for Inoperable Non-squamous Non-small Cell Lung Cancer, Followed by Both Concurrent and Maintenance Bevacizumab

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: To establish the safety and tolerability of 2 dose-levels of bevacizumab administered every 3 weeks with concurrent thoracic radiotherapy to 66 Gy,and also maintenance (15 mg/kg) bevacizumab following completion of thoracic radiotherapy

Secondary outcome: Correlate all observed toxicity with dose-volume histograms of irradiated normal organs and explore surrogate tumor end-points that may correlate with the efficacy of combined treatment with anti-VEGF targeted therapy
