AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product/protocol specified procedure, whether or not considered related to the medicinal product/protocol specified procedure. Any worsening of a preexisting condition temporally associated with the use of the product was also an AE.

Fosaprepitant is used for the prevention of chemotherapy-induced nausea and vomiting (CINV). It is being studied in both adults and children for this condition. The drug is a small molecule and is currently in clinical development, with studies having been conducted to evaluate its safety and effectiveness.
Fosaprepitant is developed by Merck & Company, Inc., which is publicly traded under the ticker symbol MRK. The company has sponsored clinical trials to investigate the drug's use in preventing chemotherapy-induced nausea and vomiting.
Fosaprepitant is in Phase 1 and Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Clinical trials have been completed to assess its pharmacokinetics, safety, and tolerability in different patient populations.
Fosaprepitant has been studied in two completed clinical trials. NCT01111851 was a Phase 1 PET study in healthy volunteers, and NCT01697579 was a Phase 2 study in children for the prevention of chemotherapy-induced nausea and vomiting. Both trials have been completed.
Fosaprepitant is a prodrug of aprepitant, meaning it is converted to aprepitant in the body. The Phase 1 trial NCT01111851 studied both aprepitant and fosaprepitant to compare their time-on-target effects using PET imaging.
