Twenty-five late CP patients received nilotinib as second-line therapy after imatinib failure. PRAME expression was measured prior to beginning nilotinib therapy using QPCR. PRAME expression was detected in 10 (83%) of 12 patients who failed nilotinib therapy compared with 5 (38%) of 13 patients who responded (P = .04).
