Indications & Usage
1 INDICATIONS AND USAGE Fosaprepitant for injection, in combination with other antiemetic agents, is indicated in adults for the prevention of: acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy (HEC) including high-dose cisplatin.

delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic cancer chemotherapy (MEC).

Limitations of Use Fosaprepitant for injection has not been studied for the treatment of established nausea and vomiting.

Pediatric use information is approved for Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc.’s Emend (fosaprepitant) for injection.

Adverse Reactions
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions ( 5.2 )] Infusion Site Reactions [see Warnings and Precautions ( 5.3 )] Most common adverse reactions in adults (≥2%) are: fatigue, diarrhea, neutropenia, asthenia, anemia, peripheral neuropathy, leukopenia, dyspepsia, urinary tract infection, pain in extremity.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The overall safety of fosaprepitant for injection was evaluated in approximately 1600 adult patients.

Adverse Reactions in Adults for the Prevention of Nausea and Vomiting Associated with MEC In an active-controlled clinical trial in patients receiving MEC, safety was evaluated in 504 patients receiving a single dose of fosaprepitant for injection in combination with ondansetron and dexamethasone (fosaprepitant regimen) compared to 497 patients receiving ondansetron and dexamethasone alone (standard therapy).

The most common adverse reactions are listed in Table 6.

Table 6 Most Common Adverse Reactions in Patients Receiving MEC* Fosaprepitant for injection, ondansetron, and dexamethasone † (N=504) Ondansetron and dexamethasone ‡ (N=497) fatigue 15% 13% diarrhea 13% 11% neutropenia 8% 7% asthenia 4% 3% anemia 3% 2% peripheral neuropathy 3% 2% leukopenia 2% 1% dyspepsia 2% 1% urinary tract infection 2% 1% pain in extremity 2% 1% *Reported in ≥2% of patients treated with the fosaprepitant regimen and at a greater incidence than standard therapy.

† fosaprepitant regimen ‡ Standard therapy Infusion-site reactions were reported in 2.2% of patients treated with the fosaprepitant regimen compared to 0.6% of patients treated with standard therapy.

The infusion-site reactions included: infusion-site pain (1.2%, 0.4%), injection-site irritation (0.2%, 0.0%), vessel puncture-site pain (0.2%, 0.0%), and infusion-site thrombophlebitis (0.6%, 0.0%), reported in the fosaprepitant regimen compared to standard therapy, respectively.

Adverse Reactions in Adults for the Prevention of Nausea and Vomiting Associated with HEC In an active-controlled clinical study in patients receiving HEC, safety was evaluated for 1143 patients receiving a single dose of fosaprepitant for injection compared to 1169 patients receiving the 3-day regimen of oral aprepitant capsules [see Clinical Studies ( 14.1 )] .

The safety profile was generally similar to that seen in the MEC study with fosaprepitant and prior HEC studies with aprepitant.

However, infusion-site reactions occurred at a higher incidence in patients in the fosaprepitant group (3.0%) compared to those in the aprepitant group (0.5%).

The following additional infusion-site reactions occurred in the HEC study and were not reported in the MEC study described above: infusion-site erythema (0.5%, 0.1%), infusion-site pruritus (0.3%, 0.0%), and infusion-site induration (0.2%, 0.1%), reported in the fosaprepitant group compared to the aprepitant group, respectively.

Because fosaprepitant is converted to aprepitant, those adverse reactions associated with aprepitant might also be expected to occur with fosaprepitant for injection.

See the full prescribing information for aprepitant capsules for complete safety information regarding studies performed with oral aprepitant capsules.

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of fosaprepitant.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Skin and subcutaneous tissue disorders: pruritus, rash, urticaria, Stevens-Johnson syndrome/toxic epidermal necrolysis [see Warnings and Precautions ( 5.2 )].

Immune system disorders: hypersensitivity reactions including anaphylaxis and anaphylactic shock [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 )].

Nervous system disorders: ifosfamide-induced neurotoxicity reported after fosaprepitant and ifosfamide coadministration.
