Researchers in Northwestern Memorial Hospital's Center for Vascular Disease at the Bluhm Cardiovascular Institute are conducting clinical research trials to learn more about treating vascular disease. The following clinical research trials, specific to vascular disease, are currently recruiting volunteers. Clinical research trials search for new and better ways to understand and treat disease. Participating in a clinical research trial is an informative learning experience for the volunteer. Please consider volunteering in a clinical research trial as your participation will contribute to important advancements of medical knowledge. |

| Name of Research Trial: | Iliac Stent Pivotal Study |
| |
| Principal Investigator: | Heron Rodriguez, MD |
| |
| IRB Project Number: | 2508-003 |
| |
| Description of Research Trial: | This research study is looking for individuals to participate in this study because they have been diagnosed with a condition known as symptomatic claudication, which patients may have noticed as pain in the legs. Some patients with peripheral arterial disease (PAD) experience leg pain while at rest. This may be due to limited blood flow to the affected leg by a constriction (narrowing) of the arteries that run through the ilium, which is part of the pelvis. A common procedure used to treat your condition involves placing a stent in the area that is blocked to improve blood flow to the leg. The purpose of this study is to evaluate the safety and effectiveness of an investigational stent when compared to other approved iliac artery stents. Follow-up will occur at 1, 6, 9, 12, 24 and 36 months after procedure and will include a physical exam and blood pressures of the arm and leg. |

| Name of Research Trial: | The US Study for Evaluating Endovascular Treatments of Lesions in the Superficial Femoral Artery and Proximal Popliteal by Using Protege Everflex Nitinol Stent System III - DURABILITY II |
| |
| Principal Investigator: | Heron Rodriguez, MD |
| |
| IRB Project Number: | 2508-002 |
| |
| Description of Research Trial: | This research study is looking for individuals who have been diagnosed with a narrowing in the arteries that are located in your leg between the groin and the knee, resulting in poor blood flow to the leg. This study place an investigational stent (Protege Everflex) in the area of narrowing in the leg to help keep the artery open.
The purpose of this study is to evaluate the safety and efficacy of the stent. Follow-up will occur at 1, 3, 6, 12, 24, 36, 48 and 60 months after procedure and will include questionnaires, ultrasound and x-rays of the stent. |

|
| Name of Research Trial: | Hematopoietic Stem Cell Transplantation for Peripheral Vascular Disease: Induction of Neoangiogenesis |
| |
| Principal Investigators: | Richard K. Burt, MD |
| William H. Pearce, MD |
| |
| IRB project: | 0141-037 |
| |
| Description of Research Trial: | This study is recruiting individuals with severe peripheral vascular disease manifested with ABI <0.8, ulcerations in legs, pain at rest and are not surgical candidates for bypass graft. Purpose of this study is to evaluate whether stem cells will repair and/or create new vessels in the leg and improve blood flow. Follow up visits will be 5 days post injection of stem cells and 1, 3, 6 and 12 months post stem cell injection. |

| Name of Research Trial: | Improving Functioning in Peripheral Arterial Disease |
| |
| Principal Investigator: | Mary M. McDermott, MD |
| |
| IRB Project Number: | 344-0081 |
| |
| Description of Research Trial: | Men and women with Peripheral Arterial Disease may qualify for the study. Most participants get free exercise sessions 3 times a week with a trainer. Most transportation reimbursed. Participation may require up to three visits a week for six months. Length of participation: one year. |

|
| Name of Research Trial: | Atherosclerotic Plaque Characterization Using High-field MRI |
| |
| Principal Investigators: | Timothy Carroll, PhD |
| Mark D. Morasch, MD |
| |
| IRB Project Number: | 1334-002 |
| |
| Description of Research Trial: | This research study is looking for participants who have a build up of plaque in the carotid artery. The purpose of this research study is to look at the ability of magnetic resonance imaging (MRI) to detect the composition of the plaque inside the artery. If a participant needs to have the plaque removed by carotid endarterectomy the plaque will be sent to pathology for further analysis. Participates will undergo a MRI scan during a single visit that will last approximately 2 hours at Northwestern Memorial Hospital, Center for Advanced Magnetic Resonance Imaging. |

|
| Name of Research Trial: | Carotid Angioplasty and Stenting versus Endarterectomy in Asymptomatic Subjects with Significant Extracranial Carotid Occlusive Disease ACT 1 |
| |
| Principal Investigator: | Mark K. Eskandari, MD |
| |
| IRB Project Number: | STU00014105 |
| |
| Description of Research Trial: | ACT I is sponsored by Abbott Vascular Devices and is a randomized, controlled, multi-center trial to demonstrate the non-inferiority of carotid artery stenting (CAS) using the Emboshield Cerebral Protection System with the Xact RX Carotid Stent System when compared to carotid endarterectomy (CEA) for the treatment of asymptomatic extracranial carotid stenotic disease.
To participate in this study, the participant must not have had a stroke or TIA (transient ischemic attack or mini stroke) within the last 6 months and have carotid artery stenosis (narrowing) > 80%. The participant must be less than 80 years old and also not have any medical condition, such as advanced congestive heart failure, unstable angina or severe lung disease, which deems them a high surgical risk. Other exclusion criteria may apply. Follow-up will occur at 30 days, 6 months and annually up to 5 years after the procedure and may include a physical and neurological examination, laboratory tests and a carotid ultrasound. The Emboshield(tm) Bare Wire Rapid Exchange (RX) Cerebral Protection System is designed to reduce distal embolization while maintaining blood flow during angioplasty and stent procedures. The Xact(tm) Rapid Exchange (RX) Carotid Stent System is intended for use during an interventional carotid artery stent procedure. The Xact stent is a permanently implantable device and is intended to re-establish and maintain vessel patency. The Xact RX Carotid Stent System is indicated for use in conjunction with the Emboshield Cerebral Protection System.
Caution - Investigational Device. Limited by Federal (or United States) law to investigational use. |

|
| Name of Research Trial: | A Pilot Study of the Prevalence of Inflammatory Mediator Gene Polymorphisms and Corresponding Circulating Protein Levels in Abdominal Aortic Aneurysm Patients |
| |
| Principal Investigator: | William H. Pearce, MD |
| |
| IRB Project Number: | 0391-022 |
| |
| Description of Research Trial: | This research study is looking for participants who have one of the following diseases: abdominal aortic aneurysm, aortic dissection or carotid disease. The objective of this study is to identify naturally occurring variations in the DNA sequences, or polymorphisms, of genes that regulate the immune response and are associated in abdominal aortic aneurysm (AAA) patients versus patients with carotid artery disease, aortic dissection and a population of healthy age- and ethnically-matched controls. Plasma protein levels from the corresponding genes will also be analyzed. Participants will have 1 outpatient visit where 4 teaspoons of blood will be drawn. |
