APF530 for nausea and vomiting prevention following cisplatin: phase 3 MAGIC trial analysis

Despite available antiemetic therapies, chemotherapy-induced nausea and vomiting (CINV) following highly emetogenic chemotherapy (HEC), particularly in the delayed phase (>24-120 h after chemotherapy), continues to impair patient quality of life and chemotherapy compliance.1 Cisplatin-based chemotherapy, classified as HEC at any dose,2 is widely used to treat cancers such as non–small-cell and small-cell lung cancer, sarcomas, germ-cell tumors, lymphoma, and ovarian cancer. Cisplatin is associated with a biphasic pattern of CINV and may induce delayedonset nausea and vomiting, reaching maximum intensity of 48-72 hours after administration and lasting 6-7 days.2 CINV after cisplatin-based therapy may be severe enough to cause chemotherapy discontinuation or dose reductions.3 Being female is a known risk factor for CINV, and because cisplatin-based regimens are often used to treat women with gynecologic cancers, this patient population is at even higher risk for CINV.4,5 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists (RAs; eg, granisetron, ondansetron, dolasetron, and palonosetron) have been the cornerstone of CINV therapy for decades and remain an integral part of contemporary antiemetic treatment regimens. Most current antiemetic guidelines for HEC recommend a 3-drug regimen, comprising a 5-HT3
