Abstract
- Background : Axitinib monotherapy obtained approval in pre-treated metastatic renal cell carcinoma (mRCC) patients and recently in combination with pembrolizumab or avelumab in the first-line setting. However, patient profiles that may obtain increased benefit from this drug and its combinations still need to be identified. Patients and Methods : Retrospective multicentre analysis describing clinical characteristics associated with axitinib long-responder (LR) population by comparing two extreme-response sub-groups (progression-free survival [PFS] ≥9 months versus disease progression/refractory patients [RP]). A multivariate logistic-regression model was used to analyse clinical factors. Efficacy and safety were also analysed. Results : In total, 157 patients who received axitinib in second or subsequent line were evaluated (91 LR and 66 RP). Older age at start of axitinib and haemoglobin levels > LLN were independent predictive factors for LR in multivariate analyses. In LR patients, median (m) PFS was 18.1 months, median overall survival (OS) was 36.0 months and objective response rate (ORR) was 45.5%. In 59 LR patients receiving axitinib in second-line, mPFS was 18.7 months, mOS was 44.8 months and ORR was 43.9%. mOS was significantly longer in second line compared to subsequent lines (44.8 versus 26.5 months; P=0.009). In LR versus RP, mPFS with sunitinib in first-line was correlated with mPFS with axitinib in second-line (27.2 versus 10.9 months P Conclusions : This study confirms the long-term benefits of axitinib in a selected population, helping clinicians to select the best sequential approach and patients who could obtain a greater benefit from axitinib. Microabstract Patients with metastatic renal cell carcinoma (mRCC) who may benefit most from axitinib still need to be identified. AXILONG study confirms long-term benefits in a selected population in which age at axitinib initiation and haemoglobin baseline levels were significantly associated although further validation may be required. First-line sunitinib outcomes were also correlated with prolonged response. These results might be helpful in real-life management of mRCC patients.
