MINI31.12 - Quality of Life for Crizotinib vs. Chemotherapy in Asian ALK-Positive NSCLC Patients (ID 845)
18:30 - 20:00 | Author(s): A. Reisman
PROFILE 1014 compared the efficacy and safety of the ALK inhibitor crizotinib with platinum based chemotherapy in previously untreated advanced ALK-positive advanced NSCLC (Pfizer; NCT01154140). The primary endpoint was progression-free survival. The main objective of this post-hoc analysis was to compare patient-reported symptom and global quality of life (QOL) between crizotinib and chemotherapy in the subgroup of patients of Asian ethnicity in the ongoing study PROFILE 1014.
Patients in the ongoing PROFILE 1014 study were randomized to crizotinib (250 mg PO bid; n= 172) or chemotherapy (pemetrexed 500 mg/m + either cisplatin 75 mg/m or carboplatin AUC 5–6; all IV q3w for ≤6 cycles; n= 171). Patient-reported outcomes were assessed at baseline, day 7 and day 15 of cycle 1, day 1 of subsequent 3-week cycles and end of treatment using the validated cancer specific questionnaire EORTC QLQ-C30 and its lung cancer module QLQ-LC13. Validated translations of the questionnaires in Asian languages (Japanese, Chinese, Korean etc) were made available. Higher scores (range 0−100) indicated higher symptom severity or better functioning/QOL. A positive change from baseline score indicates improvement for global QOL/functioning and deterioration in symptoms. Repeated measures mixed-effects analyses were performed to compare change from baseline scores between the treatment arms, with no adjustments made for multiple comparisons.
Of 343 patients randomized, 46% were of Asian ethnicity (crizotinib, n=77; chemotherapy, n=80). Completion rates at baseline were ≥95% in each group and scores were balanced. A statistically significantly greater overall improvement from baseline was observed with crizotinib compared with chemotherapy for global QOL (5.6 vs -7.7; p<0.001), emotional functioning (9.5 vs 2.7;p<0.05), physical functioning (5.0 vs - 2.7 p<0.001) and role functioning (3.7 vs. -7.2;p<0.001). A statistically significantly greater overall improvement was observed with crizotinib compared with chemotherapy for cough (-17.3 vs. -11.2; p<0.05), dyspnea (-9.5 vs.-1.1; p<0.001), pain in arm or shoulder (-11.4 vs.-2.2; p<0.001), pain in chest (-7.3 vs.3.3; p<0.001), pain in other parts (-11.2 vs. -0.4;p<0.001), fatigue (-9.9 vs. 3.9; p<0.001), insomnia (-10.3vs. -2.0; p<0.05), pain (-12.2 vs.-1.2; p<0.001) and appetite loss (-5.3 vs. 5.7; p<0.001). A statistically significantly greater overall deterioration was observed in the crizotinib arm for diarrhea (12.6 vs. 2.4; p<0.001) compared with chemotherapy. No statistically significant differences were observed for social functioning, sore mouth, dysphagia, nausea & vomiting, constipation and alopecia between crizotinib and chemotherapy.
Consistent with previously reported results in the overall study population, treatment with crizotinib showed statistically significantly greater overall improvement in patient-reported lung cancer symptoms and global QOL compared with chemotherapy in the subgroup of patients of Asian ethnicity with previously untreated advanced ALK-positive NSCLC.
