a phase iii randomized, double-blind, placebo controlled trial comparing the efficacy of gemcitabine, cisplatin and sorafenib to gemcitabine, cisplatin and placebo in first-line treatment of patients with stage iiib with effusion and stage iv non-small cell lung cancer (nsclc)

Conditions: Carcinoma, Non-Small-Cell Lung

Summary: evaluation of gemcitabine and cisplatin in combination with either sorafenib or placebo for the treatment of patients with advanced non-small cell lung cancer (nsclc)

during follow-up, it was determined that there was one additional patient on placebo that was still receiving treatment as of 06 apr 2010 and therefore 10 patients' data are reported in the current csr addendum, 6 in the sorafenib + gc group and 4 in the placebo + gc group, and as before all in the itt (non-squamous) population.

(palliative radiotherapy will be allowed as described in the prior and concomitant therapy section) * radiotherapy during study or within 4 weeks of start of study drug. (palliative radiotherapy will be allowed as described in the prior and concomitant therapy section) (for france only) * major surgery, open biopsy or significant traumatic injury within 4 weeks of first dose of study drug (bronchoscopy is allowed) * granulocyte colony stimulating factor (gcsf) or granulocyte macrophage colony stimulating factor (gmcsf), within 3 weeks of study entry (these growth factors may be used during the study thereafter).
