SUMMARY
• Crizotinib is the first-in-class ALK-TKI inhibitor
fully approved worldwide
• Consistent response rate, PFS >60% over
8 months, very favourable toxicity profile
• Evidence of clinical benefit in continuous
treatment beyond smouldering progression and
in brain metastases in selected patients with or
without radiotherapy
• Significant activity in ROS1 rearranged patients
