Review Randomized Controlled Trial Clinical TrialDose-comparative monotherapy trials of ZD1839 in previously treated non-small cell lung cancer patients.
Patients with non-small cell lung cancer (NSCLC) frequently present, or relapse, with unresectable disease that is resistant to standard chemotherapy. There is, therefore, an urgent need for new treatments for NSCLC and other solid tumors. ZD1839 (Iressa; AstraZeneca Pharmaceuticals LP, Wilmington, DE), an orally active, selective epidermal growth factor receptor-tyrosine kinase inhibitor, has shown promising antitumor responses in phase I clinical trials in heavily pretreated patients with advanced NSCLC and other solid tumors. ⋯ Symptom improvement rates (increase of at least two points on the Lung Cancer Subscale) were 43% and 35%, respectively. Both doses of ZD1839 were well tolerated in this trial. The results of IDEAL-1 and IDEAL-2 indicate that ZD1839 monotherapy may offer a single-agent alternative for patients with advanced solid tumors who have received and progressed on prior chemotherapy, many of whom have exhausted their therapy options.
