Two doses of fosaprepitant included prophylactic treatment for the three-day cisplatin-based chemotherapy induced nausea and vomiting

Abstract

Abstract Purpose Neurokinin 1 receptor antagonists included prophylactic treatment was recommended for patients who receive one-day cisplatin chemotherapy. It is unclear whether the prolonged administration of fosaprepitant is effective for three-day cisplatin-based chemotherapy induced nausea and vomiting (CINV). We aim to explore the prophylactic antiemetic efficacy and safety of two doses of fosaprepitant included regimen in the patients receiving multiple-day cisplatin chemotherapy. Methods This randomized, parallel-group, open-labelled study was conducted in nine hospitals between February 2021 and February 2023. Patients diagnosed as lung cancer and chemotherapy naive were screened. Eligible participants were scheduled to be treated with highly emetogenic chemotherapy regimen which including three days of cisplatin. Then they were randomly divided into the experimental group (two doses of fosaprepitant, Group 2DF) and the control group (one dose of fosaprepitant, Group C). The primary endpoints included the safety and the average none CINV days (NCDs). This study was registered on the website of chictr.org.cn, number ChiCTR2100042665. Results Overall, 204 participants were randomly assigned, and 198 patients were analyzed. No statistical difference in adverse events was found between the two groups. All treatment-related adverse effects for fosaprepitant observed were of grade 1–2. The average NCDs of Group 2DF was significantly more than Group C (18.21 ± 3.40 days vs 16.14 ± 5.20 days, P = 0.001). Furthermore, the better life function score was achieved in Group 2DF according to FLIE questionnaire. Conclusion The administration of two-dose fosaprepitant was safe and more effective than one dose in protecting patients from CINV induced by three-day cisplatin included chemotherapy.
