MGI PHARMA Announces Initiation of Aquavan(R) Injection Pivotal Program; Patient Enrollment Expected To Conclude By Year-End.

MINNEAPOLIS -- MGI PHARMA, INC. (Nasdaq:MOGN), an oncology- and acute care- focused biopharmaceutical company, today announced the initiation of the Aquavan(R) (fospropofol disodium) Injection pivotal program. This program consists of two randomized, double blind, multicenter phase 3 trials and an open label safety study.

The first phase 3 trial is planned to enroll a total of 300 patients undergoing colonoscopy. The second phase 3 study will enroll 250 patients undergoing bronchoscopy. The endpoints of both trials include sedation and treatment success, patient satisfaction, investigator satisfaction, and measures of sedation adequacy, recovery, clinical benefit, and safety.

"The initiation of this pivotal program advances our acute care development pipeline, which will be an important driver of MGI PHARMA's future growth," said Lonnie Moulder, President and Chief Executive Officer of MGI PHARMA. "Aquavan Injection is an excellent companion opportunity to Aloxi(R) Injection for post-operative nausea and vomiting, and together these candidates form the foundation of our acute care franchise. Results from the previously disclosed phase 2 dose ranging study indicated a clear dose response for Aquavan Injection and a promising therapeutic profile. We expect patient enrollment to be completed by the end of 2006, and plan to submit a new drug application in the first half of 2007."

In addition to the two phase 3 trials, an open label, multi-center safety study will be conducted in 150 patients undergoing minor procedures, including arthroscopy, bunionectomy, dilation and curettage, upper endoscopy, hysteroscopy, lithotripsy, arterio-venous shunt placement, and trans-esophageal echocardiograms. The goal of this study is to assess the safety of a single dose of Aquavan Injection in a variety of minor procedures.

About Aquavan(R) Injection

Aquavan (fospropofol disodium) Injection, a water soluble prodrug formulation of propofol, is a product candidate in development for minimal to moderate sedation of patients undergoing short surgical or diagnostic procedures. When administered intravenously, Aquavan Injection is converted to active propofol, a short-acting anesthetic agent. Due to its unique pharmacokinetic profile, Aquavan Injection may have broad utility as a sedative agent for short surgeries and diagnostic procedures such as colonoscopy and bronchoscopy.
