This study evaluated the efficacy and tolerability of avelumab in Chinese patients. The results showed that avelumab at different doses can stabilize the disease and have partial responses in some patients' tumors.
Aim: Data for avelumab (anti-PD-L1 antibody) in Chinese patients are limited. Patients & methods: Phase I/Ib, open-label, dose-escalation study of Chinese patients with advanced solid tumors. Primary study objectives were to evaluate the maximum tolerated dose (MTD) and pharmacokinetics (PK) of avelumab. Results: 24 patients received avelumab 3 mg/kg every 2 weeks (Q2W; n = 3), 10 mg/kg Q2W (n = 7), 20 mg/kg Q2W (n = 6) or 10 mg/kg weekly for 12 weeks and then Q2W thereafter (n = 8). MTD was not reached. Avelumab exposure was increased in higher dose groups. Partial responses occurred in two patients (confirmed in one patient); best overall response was stable disease in nine patients. Conclusion: Data for avelumab in Chinese patients with advanced solid tumors were consistent with previous global studies. Plain language summary: Avelumab is a form of medicine that falls under the category of immunotherapy. This means that it can help the immune system find and destroy cancer cells. In this study, researchers looked at the safety of avelumab in a small group of Chinese people with different types of cancer. Researchers also looked at blood levels of avelumab after treatment. Different doses of avelumab were given to different groups of people. Overall, study results for avelumab in Chinese people were similar to results from earlier studies in other countries.
