N2 - Background: Axitinib demonstrated greater progression-free survival vs sorafenib in a phase III study of previously treated patients with metastatic renal cell carcinoma. Here, we report patient-reported kidney-specific symptoms and health status, measured by the Functional Assessment of Cancer Therapy (FACT) Kidney Cancer Symptom Index (FKSI) and the European Quality of Life self-report questionnaire (EQ-5D).Methods:In all, 723 patients received axitinib (starting dose 5 mg twice daily (b.i.d.)) or sorafenib (400 mg b.i.d.). The FKSI-15, including the disease-related symptoms (FKSI-DRS) subscale, was administered on day 1 before dosing, every 4 weeks and at end of treatment (EOT)/withdrawal. Statistical methods included a mixed-effects repeated-measures model.Results:At baseline, patients in both arms had relatively high mean FSKI-15 and FKSI-DRS scores, comparable to the general US population. Subsequent on-treatment overall mean scores were similar between axitinib and sorafenib, and there was no substantial decline during treatment. Scores substantially worsened at EOT, mainly due to disease progression.Conclusion:Patient-reported outcomes were comparable for second-line axitinib and sorafenib and were maintained at relatively high levels while on treatment, but worsened at EOT. As duration of treatment was longer with axitinib than sorafenib, time to worsening of symptoms can be delayed longer with axitinib.
