Axitinib after Treatment Failure with Sunitinib or Cytokines in Advanced Renal Cell Carcinoma—Systematic Literature Review of Clinical and Real-World Evidence

Abstract

Background: We conducted a systematic literature review (SLR) to identify clinical evidence on treatments in advanced renal cell carcinoma (aRCC) after the failure of prior therapy with cytokines, tyrosine kinase inhibitors, or immune checkpoint inhibitors. Herein, we summarise the evidence for axitinib in aRCC after the failure of prior therapy with cytokines or sunitinib. Methods: This SLR was registered with PROSPERO (CRD42023492931) and followed the 2020 PRISMA statement and the Cochrane guidelines. Comprehensive searches were conducted in MEDLINE and Embase as well as for conference proceedings. Study eligibility was defined according to population, intervention, comparator, outcome, and study design. Results: Of 1252 titles/abstracts screened, 266 peer-reviewed publications were reviewed, of which 182 were included. In addition, 28 conference abstracts were eligible. Data on axitinib were reported in 55 publications, of which 16 provided efficacy and/or safety outcomes on axitinib after therapy with sunitinib or cytokines. In these patients, median progression-free and overall survival ranged between 5.5 and 8.7 months and 11.0 and 69.5 months, respectively. Conclusions: Axitinib is commonly used in clinical practice and has a well-characterised safety and efficacy profile in the treatment of patients with aRCC after the failure of prior therapy with sunitinib or cytokines.
