摘要

Background

Post-marketing surveillance focusing on hepatic function disorder was requested owing to its higher incidence in the pembrolizumab plus axitinib group than in the sunitinib group in KEYNOTE-426. We aimed to evaluate the prevalence and risk factors of adverse events (AEs) of hepatic function disorder in patients with unresectable/metastatic renal cell carcinoma (RCC) treated with pembrolizumab plus axitinib in real-world clinical practice in Japan.

Methods

Patients were observed for 9 months after starting treatment with pembrolizumab plus axitinib.

Results

In total, 193 patients were included in the safety analysis set (median age, 70 years). Most patients did not have a history of hepatic function disorder before starting treatment (96.4%, 186/193). The median treatment period was 27.1 weeks. At the 9-month data cut-off, 62.2% (120/193) of patients discontinued treatment, the most common reason being any AE in 31.1% (60/193). The incidence of AEs of hepatic function disorder was 30.1% (58/193) for any grade and 15.0% (29/193) for grade ≥ 3. Most AEs of hepatic function disorder occurred within 3 months from starting treatment. AEs of hepatic function disorder were the reason for discontinuation of pembrolizumab in 9.3% (18/193) of patients; axitinib, 7.3% (14/193); and both pembrolizumab and axitinib, 5.2% (10/193). No background factors were identified as being associated with the occurrence of AEs of hepatic function disorder.

Conclusion

There were no new safety signals for AEs of hepatic function disorder, and the incidence was consistent with that reported in KEYNOTE-426, in Japanese patients with radically unresectable/metastatic RCC treated with pembrolizumab plus axitinib.
