Abstract:
Axitinib (Inlyta(®)) is a potent, selective inhibitor of vascular endothelial growth factor receptor-1, -2 and -3. This article reviews the clinical efficacy and tolerability of axitinib in patients with previously-treated advanced renal cell carcinoma (RCC), as well as summarizing its pharmacological properties. Axitinib was effective in the second-line treatment of advanced RCC, according to the results of the pivotal, phase III AXIS trial. Median progression-free survival (PFS) was significantly prolonged with axitinib versus sorafenib (primary endpoint; independent review committee assessment); this PFS benefit was seen in patients who had received prior treatment with cytokines or sunitinib. The objective response rate was also significantly higher with axitinib than with sorafenib, with no significant between-group difference in median overall survival. Axitinib had a manageable tolerability profile in the AXIS trial, with the most commonly reported treatment-related adverse events including diarrhoea, hypertension, fatigue, decreased appetite, nausea, dysphonia, hand-foot syndrome and hypothyroidism. In conclusion, axitinib is an important option in previously-treated patients with advanced RCC.
Insights
Axitinib (Inlyta) significantly improved progression-free survival in patients with advanced renal cell carcinoma (RCC) previously treated with other therapies. It offers a manageable safety profile, making it a valuable second-line treatment option.
Area of Science:
- Oncology
- Pharmacology
- Clinical Trials
Background:
- Advanced renal cell carcinoma (RCC) remains a significant clinical challenge.
- Vascular Endothelial Growth Factor Receptor (VEGFR) inhibitors are a key therapeutic class.
- Previous treatments for advanced RCC have limitations.
Purpose of the Study:
- To review the clinical efficacy and tolerability of axitinib (Inlyta).
- To summarize the pharmacological properties of axitinib.
- To evaluate axitinib as a second-line treatment for advanced RCC.
Main Methods:
- Review of the pivotal Phase III AXIS trial data.
- Comparison of axitinib versus sorafenib in previously treated advanced RCC patients.
- Assessment of progression-free survival (PFS) and objective response rate (ORR).
Main Results:
- Axitinib significantly prolonged median PFS compared to sorafenib (primary endpoint).
- Higher ORR was observed with axitinib versus sorafenib.
- No significant difference in median overall survival between groups.
- Manageable tolerability profile with common adverse events including diarrhea and hypertension.
Conclusions:
- Axitinib demonstrates significant efficacy in second-line treatment of advanced RCC.
- Axitinib offers a favorable benefit-risk profile for previously treated patients.
- Axitinib represents an important therapeutic option for advanced RCC.
