UW Clinical Trials Center

The UW Clinical Trials Center (UW CTC) provides key leadership, infrastructure, and statistical project support to both complex and pragmatic multi-center clinical trials. Our expertise includes scientific study design, adaptive clinical trial management systems, regulatory knowledge, and overall project leadership. 


We are the coordinating center for the Resuscitation Outcomes Consortium (ROC) (Learn more) and for A-TREAT (Learn more). 


The UW Clinical Trials Center is an established team of biostatisticians, programmers, and project management staff that have extensive experience designing, planning, implementing, conducting, and monitoring large-scale clinical trials. They bring to the table a broad set of skills, and have an established foundation built on open communication and active collaborative problem solving that has ensured the success of many complex clinical trials.

The center is a critical resource for investigators at the UW and nation-wide who are striving to improve clinical approaches in emergency medicine, cardiovascular disease, and other areas.

For the past 10 years the UW CTC has been the home for the NHLBI sponsored Resuscitation Outcomes Consortium (ROC) a network that consists of 10 Regional Clinical Centers (RCCs), and a Data and Coordinating Center (DCC).  ROC provides infrastructure to advance rapid translation of promising scientific and clinical interventions to improve patient outcomes.

Current UW CTC studies include: 

A-TREAT – This study compares the incidences of bleeding and thrombosis and the transfusion requirements in patients randomized to receive TXA or a placebo for hypo-proliferative thrombocytopenia secondary to primary marrow disorders, chemotherapy, immunotherapy, radiation, and/or hematopoietic stem cell transplant.

ALPS – The primary aim of this study was to determine if survival to hospital discharge is improved with early therapeutic administration of a new formulation of IV amiodarone compared to placebo and lidocaine.

PART – This pragmatic trial compares the effectiveness of primary endotracheal intubation versus primary laryngeal tube airway management strategies upon 72-hour survival after out-of-hospital cardiac arrest.

TXA - This multi-center, Phase II trial is designed to determine if tranexamic acid initiated in the prehospital setting improves long-term neurologic outcome compared to placebo in patients with moderate to severe traumatic brain injury who are not in shock. 

PROHS – This pragmatic, multicenter, prospective observational study compares the effectiveness of two different existing prehospital resuscitation approaches in severely injured trauma patients transported by air ambulance.

PCAAM – This prospective multicenter observational study seeks to improve understanding of current out-of-hospital pediatric airway management. Patients will be enrolled from participating EMS agencies when there is a treated out-of-hospital cardiac arrest in a patient less than 18 years old. 

Epistry – The primary goal of this trial was to develop the rationale and methods for a standard, reliable, and valid epidemiologic databank of out-of-hospital cardiac arrest and life-threatening trauma cases with in-hospital outcomes after five years.
