Clinical Trial Summary

The Korea HM3 PMS is a prospective, single arm, open-label, multi-center, post market surveillance is designed to evaluate clinical and functional outcomes with the HM3 LVAS as a treatment for advanced heart failure. The PMS will enroll up to 300 patients, that meet the Health Insurance Review and Assessment (HIRA) guidelines for LVAD implantation, from up to 25 sites in South Korea. Subjects who will be implanted but not included in the PMS can be enrolled retrospectively after obtaining their informed consent. The surveillance period for this PMS is expected to be 4 years from the time of HM3 approval in Korea, concluding on June 2, 2024.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Primary Efficacy Endpoint: Number of participants with overall survival to transplant, myocardial recovery or on device support free of debilitating stroke (60 days post-stroke Modified Rankin Score >3) or reoperation for pump replacement	Overall survival to transplant, myocardial recovery or on device support free of debilitating stroke (60 days post-stroke Modified Rankin Score >3) or reoperation for pump replacement will be assessed using the Kaplan-Meier product-limit method along with a competing outcomes graph. Subjects who are urgently transplanted due to a HeartMate 3 malfunction will be considered to have experienced a primary endpoint event, as will subjects who expire, suffer a debilitating stroke or have their HeartMate 3 exchanged due to a device failure. Subjects who are transplanted (except as described above), explanted for recovery, withdraw from the trial or are lost to follow-up will be censored at that time in the analysis.	Throughout the study (approximately 4 years)
Primary	Primary Safety Endpoint: Number of cumulative occurrence of adverse events	Cumulative occurrence of adverse events will be presented as percent of patients with adverse events and events per patient year of support.	Throughout the study (approximately 4 years)
Secondary	Mean change in Six-minute Walk Test from baseline	The 6-minute Walk test will be conducted at all follow-up visits until the end of the surveillance period. Distance walked at each visit will be compared to baseline using Wilcoxon signed-rank test. To assess the overall changes, repeated measure analysis will be performed using all data collected from baseline to the end of the surveillance period. The overall mean, median, standard deviation, minimum, and maximum will be presented for all follow-up visits. Differences in walking distance between each visit and baseline will be calculated and assessed for improvements using paired, nonparametric Wilcoxon signed-rank test. In addition, box plots will be used to show changes in walking distance over time.	Through study completion, an average of 4 years
Secondary	Change in proportion of New York Heart Association (NYHA) Functional Status from baseline	Percent of subjects in each NYHA class will be presented for all follow-up visits. For comparison, patients will be grouped into NYHA Class I/II (No limitation and Slight limitation of physical activity) vs. NYHA Class III/IV (Marked limitation and Inability to carry out physical activities). McNemar's test will be used to assess if there is an increase in proportion of Class I and II subjects at each visit comparing to the baseline.	Through study completion, an average of 4 years
Secondary	Mean change in EQ-5D-5L quality of life (QoL) from baseline	Subject's quality of life will be measured by the EQ-5D-5L QoL questionnaire at baseline and all visits after HM3 implant until the end of surveillance period. The overall mean, median, standard deviation, minimum and maximum will be presented for all follow-up visits. Differences in QoL Score between each visit and baseline will be calculated and assessed for improvements using paired, nonparametric Wilcoxon signed-rank test. In addition, box plots will be used to show changes in QoL over time.	Through study completion, an average of 4 years
Secondary	Frequency of Rehospitalization and Reoperation	Frequency and reason will be reported for rehospitalization and reoperation. Freedom from rehospitalization and reoperation will be assessed using the Kaplan-Meier product-limit method.	Throughout the study (approximately 4 years)
Secondary	Number of participants with Device Malfunctions	All suspected HM3 device malfunctions will be reported. Device malfunctions will be collected under the general category of Device Deficiencies. Device deficiency is defined as an inadequacy of a medical device related to its identity, quality, durability, reliability, safety or performance, such as malfunction, misuse or use error and inadequate labeling. This includes the failure of the device to meet its performance specifications or otherwise perform as intended. Data on device malfunctions will be analyzed for the following: The component of the device involved; Days to the malfunction; Action taken in response to the malfunction; Reoperations due to malfunction; Death due to malfunction	Throughout the study (approximately 4 years)
Secondary	Incidence of adverse events including, but not limited to, neurological dysfunction, bleeding, infections and device thrombosis.	Incidence of adverse events will be assessed including, but not limited to, neurological dysfunction, bleeding, infections and device thrombosis.	Throughout the study (approximately 4 years)
