Item 8.01 Other Events
On September 4, 2007, Exelixis, Inc. (the “Company”) announced that interim data from the ongoing Phase 2 clinical trial of XL647 in previously untreated patients with Stage IIIB or IV non-small cell lung cancer (NSCLC) were presented at the 12th International Association for the Study of Lung Cancer (IASLC) World Conference on Lung Cancer. The data reported at IASLC suggest that XL647 has the potential for utility in patients with both mutated and wild type EGFR. The Company reported that over 60% of evaluable patients in the Phase 2 clinical trial have had partial responses or stable disease as their best response. Objective responses were observed in NSCLC patients with both mutationally activated and wild-type EGF receptor. The data reported at IASLC also highlighted that patients had milder EGFR-related side effects (rash and diarrhea) than previously described with other EGFR inhibitors and retained potent anti-tumor activity with durable responses and stable disease.
