Trial Outcomes & Findings for Hong Kong and Taiwan HM3 PMS (NCT NCT04703855)

NCT ID: NCT04703855

Last Updated: 2024-07-01

Results Overview

Overall survival to transplant, myocardial recovery or on device support free of debilitating 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.

PRIMARY outcome

Timeframe: Up to 6 months follow-up

SECONDARY outcome

Timeframe: Baseline and 1 Month post-implant

Population: Three subjects performed the assessment at Baseline and 1-Month, while two performed at 3 Months and one at 6 months (study premature end)

The 6-minute Walk test will be conducted at all follow-up visits until the end of the surveillance period.

SECONDARY outcome

Timeframe: Baseline and 1 Month post-implant

Population: Three subjects performed the assessment at Baseline and 1-Month, while two performed at 3 Months and one at 6 months (study premature end)

Subjects' NYHA Functional Status will be assessed at all scheduled follow-up visits until the end of the surveillance period. The New York Heart Association (NYHA) Classification provides a simple way of classifying the extent of heart failure. It classifies patients in one of four categories Class I - No symptoms and no limitation in ordinary physical activity Class II - Mild symptoms and slight limitation during ordinary activity. Class III - Marked limitation in activity due to symptoms, even during less-than-ordinary activity. Comfortable only at rest. Class IV - Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients.

SECONDARY outcome

Timeframe: Baseline and 1 Month

Population: Three subjects performed the assessment at Baseline and 1-Month, while two performed at 3 Months and one at 6 months (study premature end)

The subject's quality of life will be measured by the EQ-5D-5L QoL questionnaire at baseline and all visits after the HM3 implant until the end of the surveillance period. EQ VAS scores range from 0 to 100, where 100 is the best possible health state.
