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
