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 This is a single-arm, prospective, multi-center, post-approval U.S. registry. PAS data will be collected in the TOP Registry, which is an all-comers

registry that includes all U.S. patients who are transplanted with OCSpreserved lungs and all donor lungs that were perfused on the OCS

system (including organ turndowns and conversion to cold storage). Enrolled patients will fall into one of the following categories:

Primary Analysis Population (PAP) will be comprised of the first 266 patients transplanted with OCS-preserved donor lungs initially

deemed unacceptable (DLIDU) who meet the eligibility criteria according to the approved indication for use (IFU)

“All Other Enrolled Patients” will be comprised of patients transplanted with OCS-preserved DLIDU that do not meet the

eligibility criteria according to the approved IFU

The full PAS cohort will be comprised of the PAP and All Other Enrolled Patients.

Patient enrollment in the TOP Registry for DLIDU will continue until 266 PAP for OCS-preserved DLIDU have been completed.
Sample Size This study tests the hypothesis that 12-month patient and graft survival following transplantation with OCS-preserved DLIDU is greater than a

performance goal of 78%, which is based on the OPTN estimate of 85% and a margin of 7% (i.e., 85% - 7% = 78%). A sample size of

266 subjects provides approximately 80% power (with a one-sided alpha level of 0.025) based on the exact method for a single binomial

proportion.
Data Collection The primary effectiveness endpoint is 12-month patient and graft survival post double-lung transplant.

Secondary effectiveness endpoints include:

Incidence of PGD grade 3 at T72 hours post-transplantation

Donor lung utilization rate

Incidence of PGD grade 3 within the initial 72 hours posttransplantation

Other study endpoints include:

Number of lung graft-related serious adverse events through the

30 days post-transplant or initial hospital stay (whichever is

longer) consisting of the following SAEs (at most one per type):

o Bronchial anastomotic complications

o Major pulmonary-related infection

Survival incidence (simple proportion) at 30 days

Survival incidence (simple proportion) at initial transplant surgery

hospital discharge, if longer than 30 days.

Incidence of PGD3 at T72 hours for standard criteria donor lungs

Total ischemia and cross-clamp times for 1st and 2nd transplanted lungs

Kaplan-Meier survival estimated at Month 1, 6, 12, 24, 36, 48 and 60

Survival incidence (simple proportion) at Month 6, 12, 24, 36, 48 and 60

Kaplan-Meier BOS-free survival estimated at Month 12, 24, 36, 48 and 60

Kaplan-Meier Freedom from BOS estimated at Month 12, 24, 36, 48 and 60

Incidence of BOS at Month 12, 24, 36, 48 and 60 (BOS grading will be collected)

Incidence of re-transplantation (graft failure) at Month 12, 24, 36, 48 and 60

Kaplan-Meier transplantation-free survival estimated at Month 12, 24, 36, 48 and 60

In addition, the following OCS Lung System related data will be collected:

OCS™ Lung System preservation and ventilation parameters trends

for all transplanted lungs

Pulmonary artery pressure

o Peak airway pressure

o Vascular resistance

Lung oxygenation capacity - Final PaO2/FiO2 value on OCS System

Incidence of device malfunction during organ preservation of a

donor lung instrumented on OCS System and resulted in the donor

lungs not being used for transplantation (organ loss) or that

resulted in organs being converted to cold storage

• Incidence of and clinical reasons for donor lungs turn-down for

transplantation after OCS preservation

• Incidence of and clinical reasons for donor lungs converted to cold

storage following OCS instrumentation
Follow-up Visits and Length of Follow-up 5 years
