Post-Approval Studies (PAS) Database

The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Design Description Study Design: The overall study design for the CFS is unchanged from the pivotal portion of the IDE study.

The study design is a prospective, multicenter, single-arm, global IDE study to evaluate the safety and effectiveness of the Shockwave Coronary IVL System in de novo, calcified, stenotic coronary arteries prior to stenting.
Disrupt CAD III will be conducted as a staged pivotal study. During the first stage, up to 25 sites in the United States will be initiated to enroll up to 75 subjects (25 roll-in, 50 pivotal). Sites outside of the US may be initiated during the initial stage and do not count toward the 25 site limit or the 75 subject limit. The first 30 pivotal subjects enrolled in the study will be included in the safety assessment and their data analyzed. Results of this early safety analysis will be sent to the FDA as an IDE supplement with a request to expand the study to 50 sites worldwide. The first 25 US sites will continue to enroll up to a total of 75 subjects during FDA’s review of this IDE Supplement.
Study Population Description The study population for the Disrupt CAD III CFS is comprised of the 384 pivotal subjects enrolled in the Disrupt CAD III IDE study. Subjects in the IDE were enrolled per eligibility criteria outlined in Section 7.2. There are no new enrollments in the Disrupt CAD III CFS.
Sample Size The process for the original sample size determination is outlined in Section 9.2. There are no new enrollments required for the CFS and no new hypothesis testing.
Data Collection The primary safety endpoint for the CFS is freedom from MACE at 12 and 24 months, reported descriptively.

Other endpoints to be assessed through 2 years post-procedure include the rate of: (1) target lesion failure (TLF) and (2) all death, cardiac death, MI, TV-MI, nonprocedural MI, ID-TVR, ID-TLR, ID-non-TLR ID-non-TVR, all revascularizations (ID and non-ID), and stent thrombosis (ARC definite, probable, definite or probable) at 6, 12 and 24 months.
Robust independent adjudication of events (i.e., Clinical Events Committee) will be maintained throughout the CFS, unmodified from the pivotal portion of the study.
Follow-up Visits and Length of Follow-up Follow-up within 12-24 hours post procedure or at discharge; follow-up at 30 days; follow-up at 6, 12, 24 months
Interim or Final Data Summary
Interim Safety Information Interim results through 24 months: Major adverse cardiac events (MACE) 17.5%; Cardiac death 3.4%; Myocardial infarction 11.7%; Target vessel failure 14.9%; Target vessel revascularization 7.4% and Stent thrombosis 2.8%.
Actual Number of Patients Enrolled A total of 384 pivotal subjects were enrolled. Of these, 373 were available at 12 months for the Continued Follow-up Study.
Actual Number of Sites Enrolled Forty-two (42) global sites (U.S. and OUS) enrolled subjects in the pivotal study.
Patient Follow-up Rate 95.8% (226/236) at 24 months
Study Strengths & Weaknesses Strength: Follow-up rates through 2 years exceed 90%. Weakness: there are no hypotheses for the continued follow-up study.
