Frailty Clinical Trial - Prospective Monitoring of Angiotensin Receptor

Status Active, not recruiting

Clinical Trial Summary

The objective of this study is to establish a near-real-time prospective monitoring program in Medicare, Optum and MarketScan Research data to evaluate the benefit of new cardiovascular disease (CVD) drugs for older adults with frailty. Prospective monitoring program seeks to find early effectiveness and safety signals of new drugs by updating the analysis at regular intervals as new Medicare data become available. This study specifically aims to emulate a prospective surveillance of the effectiveness and safety of Angiotensin Receptor Neprilysin Inhibitor(ARNI) vs. a comparator, Angiotensin II Receptor Blockers (ARBs), in older adults with Heart Failure with Reduced Ejection Fraction (HFrEF) and different frailty status. This program will be enhanced by incorporating a novel claims-based frailty index, which has been shown useful in assessing how the benefits and harms of drug therapy vary by frailty.

Clinical Trial Description

Data sources of use for this study are: Medicare Database, Optum Database, and MarketScan Research Database. All data from years 2014-2020 will be included in the study. This study follows a sequential cohort monitoring design. The monitoring analysis will include 1) retrospective analysis of available data (2015-2017) at the time of first analysis (January 2021) and 2) prospective analysis of new data (2018-2020) as they become available to the researchers. Within each database, we will emulate biannual updating of data by creating a propensity score (PS)-matched cohort of new users every 6-month interval, beginning on the first marketing of ARNI (July 7, 2015-December 31, 2015, and 6-month intervals afterwards). Each sequential cohort will be followed for development of the outcomes of interest. Outcome analysis will be performed at a pre-specified 6-month interval (prospective analysis). The surveillance will be performed by frailty status (frail vs non-frail) at the time of drug initiation. The results from each database will be pooled using fixed-effects meta-analysis (assuming low heterogeneity across the databases). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
