Introduction
Fosaprepitant dimeglumine, marketed under the brand name Emend®, is a significant advancement in the treatment of chemotherapy-induced nausea and vomiting (CINV). Developed by Merck & Co., Inc., this drug has undergone extensive clinical trials and has been approved globally for its efficacy in managing CINV.
Clinical Trials and Efficacy
Approval and Initial Studies
Fosaprepitant dimeglumine was first approved by the European Union in January 2008 and later by the US FDA in February 2016 for the prevention of delayed nausea and vomiting in adults receiving moderately emetogenic chemotherapy (MEC)[1][4].
Phase III Trials
A pivotal phase III trial compared a single IV infusion of fosaprepitant dimeglumine (150 mg) combined with ondansetron and dexamethasone to a control regimen of ondansetron and dexamethasone alone. The results showed that the fosaprepitant regimen achieved a complete response (no vomiting and no rescue medication) in nearly 79% of patients in the delayed phase and 77% in the overall phase, significantly higher than the control regimen[1].
Comparative Studies
Studies have also compared fosaprepitant dimeglumine to aprepitant, another NK1 receptor antagonist. A randomized, double-blind, non-inferiority clinical study involving 644 patients receiving cisplatin-based chemotherapy found that the antiemetic effects of fosaprepitant and aprepitant were comparable, with complete response rates of 71.96% and 69.35%, respectively[3].
Pediatric Use
Although the majority of studies have focused on adult patients, there is emerging evidence of fosaprepitant dimeglumine's efficacy in pediatric patients. A small-scale study indicated that fosaprepitant dimeglumine is safe and effective in preventing CINV in children as young as 10 months, though larger, multi-center trials are needed to confirm these findings[3].
Safety Profile
Fosaprepitant dimeglumine has been shown to be generally well-tolerated. Common adverse reactions include fatigue, diarrhea, neutropenia, and asthenia. Infusion-site reactions are relatively rare but can occur[2][3].
Market Analysis
Market Size and Growth Projections
The market for fosaprepitant dimeglumine API is experiencing significant growth, driven by the increasing incidence of cancer and the need for effective antiemetic treatments. As of 2023, the market size was valued at several billion USD, with projections indicating it will reach even higher values by 2031[2].
Market Segmentation
The market is segmented based on type (products with purity ≥98% and those with purity <98%), application (primarily in fosaprepitant dimeglumine injections), and geography (North America, Europe, Asia-Pacific, South America, and the Middle East and Africa)[2].
Geographical Dynamics
North America and Europe dominate the market due to high healthcare expenditure and increasing cancer treatment demands. North America holds an estimated market share of 40%, followed by Europe at 30%. The Asia-Pacific region is also experiencing rapid growth due to increasing cancer incidence and improving healthcare infrastructure[2][5].
Economic Value and Cost-Effectiveness
Cost-Effectiveness Studies
Despite higher initial costs, fosaprepitant dimeglumine has been shown to be cost-effective in the long term. A decision tree model and budget impact analysis in China indicated that while fosaprepitant dimeglumine had a similar treatment effect to aprepitant, it was cost-effective at the current willingness-to-pay threshold. Its inclusion in national reimbursement lists has expanded coverage to more patients, although it may lead to a slight increase in medical insurance payments[2].

Key players in the fosaprepitant dimeglumine market include Merck, Dr. Reddy’s Laboratories Ltd., Tecoland Corporation, Wisdom Pharmaceutical Co. Ltd., and Glenmark Pharmaceuticals[2].
Future Outlook
The future outlook for the fosaprepitant dimeglumine market is promising, driven by ongoing research, regulatory approvals, and increasing demand for effective antiemetic treatments. As cancer treatment protocols evolve, the role of fosaprepitant dimeglumine is likely to remain significant[2].
"Fosaprepitant is effective and safe in the control of CINV in cancer patients receiving highly emetogenic chemotherapy (HEC), and may be an alternative option for antiemetic therapy. In general, fosaprepitant is worthy of clinical promotion and has a large market potential."[3]
