Study Design and Results
In this multinational, prospective, observational study, physicians/nurses (N=13/11) estimated the frequency of acute (Day 1) and delayed (Days 2-5) nausea
and vomiting after first administration of highly or moderately emetogenic chemotherapy and antiemetic treatment. Chemotherapy-naive patients older than
18 years (N=298) received either single-agent or combination therapy: highly emetogenic chemotherapy, such as cisplatin >50 mg/m2 or cyclophosphamide
>1500 mg/m2, or moderately emetogenic chemotherapy, such as doxorubicin >20 mg/m2 or cyclophosphamide <1500 mg/m2. Patients recorded emetic
episodes, nausea assessments, and antiemetic medications taken daily in a 6-day diary, which was then evaluated and matched against the medical
predictions. Most patients (97%) received 5-HT3 antagonist; 78% also received a corticosteroid (mean 2.3 antiemetic agents per patient). The most common
duration of 5-HT3 antagonist and corticosteroid therapy was 3 days.

Study Design and Results
In a multicenter, randomized, double-blind, placebo-controlled clinical study, combination therapy with EMENDTM was compared with a 5-HT3 receptor antagonist regimen
in 530 cisplatin-naive patients receiving a chemotherapy regimen that included cisplatin ≥70 mg/m2. Some patients also received additional chemotherapeutic agents.
The primary clinical end point was “complete response” (overall, Days 1–5), defined as no vomiting and no rescue medication for nausea or vomiting. The percentage of
patients achieving a complete response over 5 days were significantly improved with the EMEND™ regimen than the control regimen, respectively: overall phase 72.7%
vs 52.3%; acute phase 89.2% vs 78.1%; delayed phase 75.4% vs 55.8%, p<0.001). The most common drug-related adverse experiences reported in patients treated with
the aprepitant regimen and greater than control therapy were: hiccups, asthenia/fatigue and nausea occuring after day 5.
Therapy Regimen
*Combination therapy with EMENDTM=3 days EMENDTM (125 mg PO on Day 1 and 80 mg PO once daily on Days 2 and 3); plus 1 day ZOFRAN® (ondansetron) (32 mg IV
on Day 1); plus 4 days dexamethasone (12 mg PO on Day 1 and 8 mg PO once daily on Days 2–4).
**Control regimen=ZOFRAN® was administered at maximum dose of 32 mg IV on Day 1 and not followed by oral 5-HT3 therapy on Days 2-5.
