Mutations status in ALK and other escape genes (e.g., EGFR, KRAS) will require 20 mL of blood to be collected at baseline, at Treatment Visit 3 (Week 16), and subsequently at every second treatment visit (every 16 weeks) (see Appendix 1 for detailed information) until disease progression and during treatment post-disease progression in case of isolated, asymptomatic progression of disease in the CNS. For sample handling procedures, storage conditions, and shipment instructions, see the laboratory manual. These samples will not be collected in countries where the regulatory agency or the Institutional Review Board (IRB) does not allow genetic testing.
