Now, at least a few of them can.<\/p>\n<p>\nUNMC is the clinical coordinating center for a $12.2 million multi-center randomized placebo-controlled clinical trial of medical management of aortic aneurysm disease.<\/p>\n<p>\nThe management would be via a pill, which some scientists believe could significantly slow aneurysm growth. The study is being conducted under the auspices of a grant from the National Institutes of Health.<\/p>\n<p>\nThe <a href=\"http:\/\/clinicaltrials.gov\/show\/NCT01756833\">Non-Invasive Treatment of Abdominal Aortic Aneurysm Clinical Trial (NTA<sup>3<\/sup>CT)<\/a> aims to enroll 250 patients with the collaboration of 15 top academic medical centers across the U.S.<\/p>\n<p>\nIn addition to UNMC, the project&rsquo;s pillar institutions include the <a href=\"http:\/\/umm.edu\/?gclid=CNKenvuNxLgCFYdQ7AodhV4Aag\">University of Maryland Medical Center<\/a> &ndash; for clinical trials management and design; <a href=\"http:\/\/www.med.wisc.edu\/\">University of Wisconsin School of Medicine and Public Health<\/a> &ndash; for aortic imaging; and <a href=\"http:\/\/medschool.wustl.edu\/\">Washington University School of Medicine in St. Louis<\/a> &ndash; for blood, lab and genetic testing.<\/p>\n<p>\nFifty percent of the trial&rsquo;s enrollees will receive the antibiotic doxycycline, an inexpensive generic now widely used for acne and other conditions. Dr. Baxter&rsquo;s preliminary research in animal models shows the drug inhibits the enzymes which weaken aortic walls, thus causing aneurysms.<\/p>\n<p>\nIf successful, it&rsquo;s an inexpensive, noninvasive, proactive approach.<\/p>\n<p>\nDr. MacTaggart, a vascular surgeon, said the surgery to repair aneurysms can come with a mortality rate of up to 3 percent &ndash; and a cost of about $20,000. More than 40,000 such procedures are done each year nationwide.<\/p>\n<p>\n&ldquo;Multiply all of that together,&rdquo; Dr. MacTaggart said. &ldquo;If you can change a $100,000 operation to $10 a year for some pills, it&rsquo;s going to save the health care system a <em>ton<\/em> of money.&rdquo;<\/p>\n<p>\nBut, the study will show more than whether or not the pill works. It should also garner a host of invaluable information.<\/p>\n<p>\nAnd its enrollees will be doing something about the disease, rather than just biding time.<\/p>\n<p>\nAortic aneurysms affect 3 percent to 5 percent of the population, but are most common in men age 65 and older, often smokers with a family history.<\/p>\n<p>\n&quot;It&#39;s considered a silent killer,&quot; Dr. Baxter said, &quot;because there are no symptoms until it ruptures. Most aneurysms we find by luck when imaging is done for other medical conditions.&quot;<\/p>\n<p>\nAnd then, there is only worrying and waiting as it grows.
