In January 2005, the oversight responsibility of the Post-Approval Studies Program was transferred to the Division of Epidemiology (DEPI) of the Office of Surveillance and Biometrics (OSB)/Center for Devices and Radiological Health (CDRH).
The CDRH Post-Approval Studies Program encompasses design, tracking, oversight, and review responsibilities for studies mandated as a condition of approval of a premarket approval (PMA) application, protocol development product (PDP) application, or humanitarian device exemption (HDE) application. The program helps ensure that well-designed post-approval studies (PAS) are conducted effectively and efficiently and in the least burdensome manner.
CDRH has established an automated, internal tracking system that efficiently identifies the reporting status of active PAS studies ordered since January 1, 2005 based on study timelines incorporated in study protocols and agreed upon by the CDRH and applicants. This system represents CDRH's effort to ensure that all PAS commitments are fulfilled in a timely manner.
In addition, CDRH launched this publicly available webpage to keep all stakeholders informed of the progress of each PAS. The webpage displays general information regarding each PAS, as well as the overall study status (based on protocol-driven timelines and the adequacy of the data) and the applicant's reporting status for each submission due.

Detailed Study Protocol Parameters
Study Design Description
This is a prospective, multi-center study designed to observe clinical outcomes in patients receiving the
TAXUS Liberte-Paclitaxel-Eluting Coronary Stent and prasugrel as part of a dual antiplatelet therapy drug regimen. This is a consecutively-enrolled study with follow-up through 5 years. This study will also contribute patient data to an FDA-requested and industry-sponsored research study that will evaluate the optimal duration of dual antiplatelet therapy study.
Study Population Description
This device is indicated for improving luminal diameter for the treatment of de novo lesions
< 28 mm in length in native coronary arteries > 2.5 mm to < 4.0 mm in diameter. Study patients with ischemic heart disease due to stenotic lesions in either native coronary arteries or coronary artery bypass grafts undergoing percutaneous coronary intervention with TAXUS Liberté stent placement and no contraindications to prolonged dual antiplatlet therapy are eligible to be enrolled in this study.
4,200 consecutive patients, 100 sites
The primary endpoint is the rate of cardiac death or myocardial infarction at 12 months.
Followup Visits and Length of Followup
Patients will be followed annually to five years. Clinical follow-up will occur at 15, 24,
