The University of Iowa is looking for volunteers with high cholesterol levels to take part in the study of a promising new drug. Dr. Hal Schrott is a professor of epidemiology and internal medicine at the U-of-I, and he’s running the study.Men and women between the ages of 21 and 65 are needed who have a trigliceride level over 150 but less than 600 and they have to have a low H-D-L, less than 40 for men and less than 50 for women. Dr. Schrott says the study will run 18 weeks.Schrott says the drug that’ll be used doesn’t even have a name yet — he only knows it by a number — but he says it shows much promise.It could effect triglycerides and may prevent diabetes. Study participants won’t be paid for taking part but will be paid for travel expenses if they live far away. The study runs 18 weeks and will involve at least nine trips to Iowa City.
