Background:
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.
Methods:
Patients in the ongoing PROFILE 1014 study were randomized to crizotinib (250 mg PO bid; n= 172) or chemotherapy (pemetrexed 500 mg/m[2] + either cisplatin 75 mg/m[2] 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.
Results:
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.
Conclusion:
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.
