תבנית:נתוני סל/אירסה - Iressa: הבדלים בין גרסאות

Iressa is indicated as monotherapy for the continued treatment of patients with locally advanced or metastatic non-small cell lung cancer after failure of both platinum-based and docetaxel chemotherapies who are benefiting or have benefited from Iressa. In light of positive survival data with other agents including another oral EGFR inhibitor physicians should use other treatment options in advanced non-small cell lung cancer patient populations who have received one or two prior chemotherapy regimens and are refractory or intolerant to their most recent regimen. The effectiveness of Iressa was initially based on objective response rates . Subsequent studies intended to demonstrate an increase in survival have been unsuccessful. Specifically results from a large placebo-controlled randomized trial in patients with advanced NSCLC who progressed while receiving or within 90 days of the last dose of chemotherapy or were intolerant to the most recent prior chemotherapy regimen did not show an improvement in survival . Results from two large controlled randomized trials in first-line treatment of non-small cell lung cancer showed no benefit from adding Iressa to doublet platinum-based chemotherapy
