A Multicenter Phase III, Double-Blind, Placebo-Controlled, Parallel Study of ADL-8-2698 in Opioid-Induced Postoperative Bowel Dysfunction/Postoperative Ileus
Patients undergoing major abdominal surgery are at highest risk for developing postoperative
ileus (POI), occurring in nearly all cases. Signs and symptoms of POI may include abdominal
distention, bloating, persistent abdominal pain; nausea and/or vomiting; delayed passage or
inability to pass flatus or stool; and inability to tolerate a solid diet. This study will
test the ability of alvimopan 6 mg or 12 mg given 2 hours before the scheduled start of
surgery to hasten the recovery of GI function in patients undergoing major abdominal surgery
(bowel resection or abdominal hysterectomy).

(bowel resection or abdominal hysterectomy).
Postoperative ileus (POI) is temporary slowing down or stopping of bowel function and a
slowing down of movement of contents of the intestines. This functional impairment persists
for a variable duration following surgery, usually resolving within 1 day in the small
intestine, 1 to 3 days in the stomach and 3 to 5 days in the colon. When POI persists for
more than 5 days, it is generally considered severe, sometimes referred to as complicated or
prolonged POI, and increases the risk for related morbidity. No drug therapy has been shown
to consistently shorten the duration of POI. This study is designed to demonstrate that
alvimopan, a novel, peripherally acting mu opioid receptor antagonist, accelerates the
recovery of GI function in patients undergoing bowel resection of hysterectomy.
