Boston Scientific initiates study of Promus PREMIER Coronary Stent System in underserved patient populations

MARLBOROUGH, Mass., Oct. 20, 2014 -- As part of its commitment to innovation and improving patient outcomes, Boston Scientific Corporation (NYSE: BSX) has initiated the PLATINUM Diversity trial to evaluate the clinical performance of the Promus PREMIER Everolimus-Eluting Platinum Chromium Coronary Stent System in underserved patient populations, including women and people of color. The Promus PREMIER Stent System is the company's latest durable polymer drug-eluting stent (DES) and is approved by the U.S. Food and Drug Administration (FDA) to treat coronary artery disease. Wayne Batchelor, M.D., F.A.C.C., F.S.C.A.I., and co-principal investigator, enrolled the first patient in the PLATINUM Diversity trial at Tallahassee Memorial Hospital, in Tallahassee, Florida.

Historically, large-scale clinical trials in cardiology have had a disproportionately low inclusion of women and non-white patients. As a result, physicians have had little data on which to base their clinical decisions when treating these patients.  The PLATINUM Diversity trial is aligned with recent actions taken by the FDA, including implementation of FDASIA 907: Inclusion of Demographic Subgroups in Clinical Trials, and with the Boston Scientific Close the Gap education initiative which aims to promote health equity and ensure all patients receive optimal health care regardless of age, gender, race, ethnicity or primary language.  

"Creating a treatment plan specifically tailored to underrepresented populations has long been a challenge in clinical practice due to the lack of specific outcomes data from cardiovascular clinical trials," said Roxana Mehran, M.D., director of Interventional Cardiovascular Research and Clinical Trials at Icahn School of Medicine at Mount Sinai Medical Center and principal investigator. "I am excited to be part of a trial that aims to fill the data demographic gap in the stent space and provides physicians with additional knowledge to make the best treatment decisions possible for their patients."

The PLATINUM Diversity trial is an observational, prospective, multicenter, open-label, single-arm, post-approval study that will enroll up to 1,500 patients from understudied populations, specifically women, black Americans, Latinos/Hispanics, American Indians or Alaska Natives, at up to 65 sites in the U.S. The primary study endpoint is the rate of the composite of death, myocardial infarction and target vessel revascularization through 12 months. Initial data are expected to be available in 2016.

"The number of minority and female patients participating in clinical trials is often not representative of disease epidemiology," said Dr. Batchelor. "Since different populations may respond differently to various therapies, it is important that we generate data to help clinicians make evidence-based treatment decisions for all patients."

According to the U.S. Centers for Disease Control and Prevention, cardiovascular disease is the leading cause of death for all Americans, including women and minorities.[i] Despite this reality, women represent less than one-third of those in cardiovascular trials conducted since 2006;[ii] black Americans represent about 12 percent of the U.S. population, yet they comprise just five percent of patients in clinical trials.[iii]

"We know that more women are dying from heart disease than any other cause.  WomenHeart is advocating that the FDA implement strategies to ensure appropriate representation of women in clinical research and that results from trials be analyzed, reported by sex and easily accessible," said Lisa M. Tate, chief executive officer, WomenHeart: The National Coalition for Women with Heart Disease.  "Doctors and patients can't assess which treatment is best if meaningful data for women are not available."

The PLATINUM Diversity trial, with its focus on the use of drug-eluting stent technology in women and minorities, further demonstrates the commitment of Boston Scientific to develop and conduct innovative clinical trials that provide important data to help physicians and patients make informed decisions.

About Coronary Artery Disease

Coronary artery disease is a narrowing of blood vessels that supply blood and oxygen to the heart.  Patients with coronary artery disease may experience pain, shortness of breath and fatigue. They may also be at risk for a heart attack. One treatment option is the placement of a stent in the artery to help keep it open and allow the blood to flow more freely.

About the Promus PREMIER Stent System

The Promus PREMIER Stent System was developed with extensive input from interventional cardiologists and is designed to provide best in class acute and clinical outcomes.

The everolimus drug and polymer stent coating have been studied in multiple randomized clinical trials demonstrating long-term safety and efficacy.  The PLATINUM Clinical Trial Program demonstrated exceptional safety and efficacy of the PROMUS Element Stent System (Platinum Chromium Everolimus-Eluting stent) when compared to the Xience V Stent (Cobalt Chromium Everolimus-Eluting stent). Further review of the PLATINUM data demonstrated that the PROMUS Element Stent System is associated with significantly less vessel straightening in severely angulated lesions and has resulted in numerically lower clinical event rates out to three years.

The Promus PREMIER Stent System received CE Mark approval in February 2013 and has been available in the U.S. since November 2013.
