Impact of Therapy Management on Axitinib-Related Adverse Events in Patients with Advanced Renal Cell Carcinoma Receiving First-Line Axitinib + checkpoint Inhibitor

Clinical Genitourinary Cancer, 2023


There are limited real-world data on the effectiveness of strategies used to manage adverse events (AEs) in patients with advanced renal cell carcinoma (RCC) treated with axitinib. This retrospective chart review examined the AE profile and effect of axitinib modifications on AE resolution/improvement and treatment discontinuation.


A retrospective physician-administered chart review was conducted. Adult patients with advanced RCC treated with first-line axitinib plus checkpoint inhibitor (CPI) therapy (ie, avelumab or pembrolizumab) and who had documented frequently reported axitinib-related AEs of fatigue, diarrhea, nausea, hypertension, or palmar-plantar erythrodysesthesia were included. Physician characteristics, patient characteristics, AE characteristics, AE management strategies used, AE resolution/improvement, and treatment duration were described. The effect of strategies used to manage AEs (axitinib dose reduction or treatment interruption) on AE resolution/improvement was evaluated by logistic regression.


Among 219 patients (median age: 62 years, 65% male), 70 (32%) were treated with axitinib + avelumab and 149 (68%) received axitinib + pembrolizumab. Axitinib modifications increased the likelihood of AE resolution/improvement compared with no modifications (adjusted odds ratio: 6.34, P < .001). In the subset of patients who discontinued treatment among those with or without axitinib modifications, mean treatment duration was 7.0 and 1.7 months, respectively.


Toxicities experienced by patients with advanced RCC treated with first-line axitinib-CPI in the real world can be effectively managed by axitinib modifications, thereby prolonging treatment duration.
