Cisplatin/Etoposide/Radiotherapy Followed by Consolidation Sorafenib for Inoperable Stage III Non-Small Cell Lung Cancer

Sorafenib has demonstrated in vivo anti-tumor efficacy. This trial will evaluate the safety and preliminary efficacy of sorafenib following chemoradiation in locally advanced NSCLC.

Outline: This is a multi-center study.

Chemotherapy/radiation therapy (2 cycles)

* Cisplatin 50 mg/m2 IV days 1 and 8 of 28 day cycle
* Etoposide 50 mg/m2 IV days 1-5 of 28 day cycle
* Concurrent chest radiation (planned dose is 5940 cGy with an additional, optional boost of 1080 cGy to a total allowed dose of 7020 cGy) with the following:

Maintenance therapy of Sorafenib 400 mg PO BID of 28 day cycle, to begin a minimum of 6 and maximum of 9 weeks from completion of chemo-radiotherapy until PD, intolerable toxicity, or up to 1 year.

Patients with progressive disease will discontinue treatment.
