Institute for Clinical Research and Health Policy Studies

Center for Cardiovascular Health Services Research

For over 25 years, the ICRHPS Center for Cardiovascular Health Services Research (CCHSR) has focused on the development of treatment strategies, decision aids, methods, and systems aimed at improving medical care, especially emergency and cardiac care.  CHHRS researchers have conducted multiple large national clinical effectiveness trials to demonstrate cardiac predictive instruments. Read more about CCHSR’s specific research programs below. 

This and related work has included conduct of multiple large national clinical effectiveness trials, including demonstrating better treatment and clinical outcomes for patients with acute coronary syndromes and acute myocardial infarction.

The Johns Hopkins University-Tufts Trial Innovation Center (JHU-Tufts TIC) was established in 2016 to provide Clinical and Translational Science Award (CTSA) investigators across the country with world leading expertise in state-of-the-art trial design and execution of multisite studies. The JHU-Tufts TIC is one of three TICs nationally that will provide a framework for excellence in clinical trial practice to allow new treatments and drugs to reach patients faster and in a more cost effective manner.  The TICs, at JHU-Tufts, Utah and Duke-Vanderbilt, along with a Recruitment Innovation Center (RIC) at Vanderbilt, and the 64 CTSA Program Hubs make up the NCATS Trial Innovation Network which will support investigators with protocol development, implementing central institutional review boards (IRBs) and recruitment plans while also developing and disseminating sustainable innovative practices across the network.

The Trial Innovation Network has established a new model of collaboration in multisite clinical trials by linking local resources at the 64 national NIH-supported CTSA Hubs and their more than 500 affiliated clinical institutions spanning all domains of healthcare, with the centralized expertise at the TICs and RICs. This will ultimately transform how clinical trials are conducted.

The JHU-Tufts TIC will lead two innovation projects; 1) the development and implementation of clinical trial performance metrics, and 2) novel trial design such as ‘efficacy to effectiveness’ (E2E) to generate evidence for optimal use of new treatments.

The JHU-Tufts TIC will be jointly led by principal investigators from both institutions, Harry P Selker, MD, Executive Director of ICRHPS and Dean of the Tufts CTSI at Tufts University, Daniel F. Hanley, MD the Jeffrey and Harriet Legum Professor of Neurology and Director of BIOS, and Daniel Ford, MD, MPH, the David M Levine Professor of Medicine and Vice Dean for Clinical Research in the Johns Hopkins School of Medicine.

Tufts Medical Center, led by researchers at the CCHRPS is one of 15 ‘Hub’ sites in a new national emergency medicine clinical trials network. The NIH-sponsored national SIREN Network will develop and conduct large-scale clinical trials to test new treatments in areas such as traumatic brain injuries, seizures, spinal cord injuries, cardiac arrest, heart attacks, congestive heart failure, pulmonary embolism, blood transfusion, and more.

The SIREN Network is an NIH cooperative five year award that will nationally bring together 15 ‘Hub’ institutions and their local ‘spoke’ sites, to provide a national infrastructure for conducting large multi-site clinical trials.

Tufts Medical Center, together with partners from the Tufts Medical Center Clinical and Translational Science Institute (CTSI), Clinical Research Network (Maine Medical Center, Central Maine Medical Center, Eastern Maine Medical Center, Baystate Medical Center, and Lahey Hospital and Medical Center), form the Tufts SIREN Hub and Spokes and will act as a coordinated network to develop and execute emergency medicine trials. The Tufts CTSI Clinical Research Network encompasses an urban quaternary care academic health center and large community-based hospitals in urban, suburban and rural areas, a mix that reflects much of the range of the 5,000-plus hospitals in the US, allowing for greater generalizability of research findings to clinical practice.

The IMMEDIATE Trial, funded by the National Heart, Lung and Blood Institute (NHLBI) from 2006-2011, was a clinical effectiveness, multisite randomized control trial to assess the use of glucose-insulin-potassium (GIK) for acute coronary syndromes (ACS). This was the first double-blind placebo controlled study of GIK for ACS, and the first to assess the use of GIK in the pre-hospital setting as administered by paramedics. The IMMEDIATE Trial demonstrated that very early administration of GIK by emergency medicine services (EMS) personnel reduced the incidence of cardiac arrest or mortality by 50% for individuals with ACS, and by 60% for those with a more severe form of myocardial infarction known as STEMI (ST-elevation myocardial infarction).

The IMMEDIATE Trial used ACI-TIPI and TPI predictive instruments, embedded into electrocardiographs to help to maximize identification of eligible participants in the pre-hospital setting by paramedics. While the results of the IMMEDIATE Trial were very encouraging, because prior GIK studies had not been positive - even though they gave GIK later than would be expected to work and had not been double-blind placebo studies such as IMMEDIATE, FDA has requested a confirmatory trial (IMEMDIATE-2).

The IMMEDIATE-2 Trial design is very similar to the original IMMEDIATE Trial with some notable exceptions. Firstly, enrollment will take place in both the Emergency Department (ED) and EMS settings, as opposed to only EMS settings for the IMMEDIATE Trial. This more accurately reflects the typical clinical distribution of patients with ACS, where up to 50% come directly to the ED and will help to increase the opportunities for enrollment. Secondly, the primary endpoint will be a Finkelstein-Schoenfeld hierarchical endpoint of the combination of all-cause 30-day mortality, in-hospital cardiac arrest, and infarct size.

IMMEDIATE-2 is anticipated to begin Q3 2018 and will enroll 1,600 participants.

Efficacy to Effectiveness (E2E) is an approach to clinical trial design that addresses the effectiveness and safety gaps that often occur in standard randomized controlled trials. E2E Trials are designed prospectively, whereby an effectiveness trial would commence seamlessly upon completion of the efficacy trial. This approach offers an opportunity for improved understanding of how a treatment will work in more usual real-world clinical settings.

Reasons for adopting an E2E Trial Design:   

  • To provide a broader understanding of the treatment
  • To allow understanding heterogeneity of treatment effects for special patient groups
  • Greater evidence for physicians, payers, providers and patients.
  • Better translation of research results into an impact on the public
  • Potential for wider target population

The JHU-Tufts Trial Innovation Center (JHU-Tufts TIC) want to work with interested CTSA investigators nationally to develop the E2E concept and understand the challenges and potential solutions for better linking efficacy and effectiveness trials. Through consultations and workshops we will work with investigators to design the logistics and features of a specific intervention, including site selection, inclusion and exclusion criteria, data issues, engagement of industry, and regulatory matters related to approval for marketing.

The team at Tufts MC working on this project includes highly experienced comparative effectiveness researchers, trialists, clinical epidemiologists, statisticians, pharmacologists, and experts in drug development and testing, from academics, industry, and the FDA. We will offer support, tailored to the needs of the investigator and study team in:
  1. Helping design and plan for the operationalization of E2E trials, via consultations, all-day Design Labs, and other approaches as required
  2. As a Coordinating Center, helping conduct an E2E trial, in conjunction with lead investigators and sponsors
  3. Further developing and implementing the E2E and related trial designs

The JHU-Tufts TIC, in collaboration with MIT’s NEWDIGS program is hosting a series of Design Labs, the next of which will take place in March 2018 in Boston. This interactive multi-stakeholder event will provide a venue to discuss the considerations and challenges of designing a Phase 2 or Phase 3 E2E multi-site clinical trial that supports the generation of robust efficacy and effectiveness data. These DesignLabs are an opportunity to bring together physicians, payers, industry, regulatory agencies and patient groups for structured and open conversation under strict confidentiality agreements. One of the earliest projects that the NEWDIGS team helped bring to fruition was adaptive licensing, which is now part of the regulatory pathway in Europe.

The JHU-TIC, in collaboration with the Tufts Center for the Study of Drug Development (CSDD) are leading a project to define a set of common, generalizable trial performance metrics and associated benchmark values.

Using both prospective landscape scan and retrospective regression analysis, we will identify a set of metrics that are predictive of specific performance outcome measures. These metrics will be developed and disseminated within the Trial Innovation Network to allow sites to measure and improve performance.

Training materials outlining metric collection and analysis, operational guidelines for each metric will be developed, prior to a pilot of these metrics in the Tufts MC CTSI Clinical Research Network.

The JHU-Tufts team will work closely with the CTSA Common Metrics Initiative as they roll out the new Accrual Metric. JHU and Tufts are two of the sites included in the Accrual pilot.

More updates will be posted here as the project progresses.
