Pentoxifylline Treatment of Acute Pancreatitis

Pentoxifylline Treatment in Acute Pancreatitis; A Double-Blind Placebo-Controlled Randomized Trial

The purpose of this study is to determine the effects (good and bad) of giving a drug called pentoxifylline to patients with acute pancreatitis, to see if it can improve blood tests associated with inflammation (tissue damage). Pentoxifylline is approved by the US Food and Drug Administration (FDA) for treatment of circulation problems, but its use in this study is investigational, which means that the FDA has not approved it for the treatment of pancreatitis. However, the FDA has allowed the use of pentoxifylline in this research study.

Subjects will be put in one of two groups by chance (as in the flip of a coin). This is done so that neither you nor the investigator will know which group you are in.

You will be put into either the treatment group or the control group.

• The treatment group will receive a drug called pentoxifylline
• The control group will receive a placebo (matching pill that has no medication in it) You will take the pills by mouth starting from the time of admission. You will receive a total of 9 doses over the first three days of your hospitalization (72 hours).

When subject have standard patient care blood draws, additional blood will be taken to do the research tests. The additional blood tests will be done every day for up to 5 days, after the administration of study drug or till the time of discharge whichever occurs earlier. The additional tests will require about 2 teaspoons (10 ml) of blood per day; the maximum amount of extra blood taken would be less than 3 tablespoons (40.0 ml). Information from your medical record will be gathered while you are hospitalized and after your discharge. The study will continue to gather clinical follow up information up to four months.
