Brief Summary:
The ALLEVIATE-HF study is a prospective, randomized, controlled, blinded, multi-site, interventional, investigational device exemption (IDE) pivotal study. The purpose of the study is to demonstrate the safety and efficacy of a patient management pathway that utilizes an integrated device diagnostic-based risk stratification algorithm to guide patient care in subjects with NYHA class II and III heart failure, and to demonstrate the safety of the Reveal LINQ™ system and procedure in the study population.

Condition or disease Intervention/treatment Phase
Heart Failure NYHA Class II Heart Failure NYHA Class III Device: Reveal LINQ™ Insertable Cardiac Monitor with investigational ALLEVIATE-HF RAMware download Other: Medication intervention Not Applicable

Detailed Description:
The study will utilize the market released Reveal LINQ™ Insertable Cardiac Monitor with an investigational ALLEVIATE-HF RAMware download. The study will enroll up to 900 subjects at up to 75 sites in the US. Subjects will be followed until the last enrolled subject is followed for 7 months or until the end of the study, whichever occurs first, or until time of study exit or death as applicable, but no longer than 36 months.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 900 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Following Reveal LINQ™ device insertion, subjects will be randomly allocated in a blinded fashion in a 1:1 ratio to either the observation arm or the intervention arm. Subjects in the observation arm will start with an observational period of 13 months and then transition to the intervention arm for the remainder of their participation in the study.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: Study site personnel and subjects will remain blinded to the subject's randomization assignment until the 13-month timepoint at which point the subjects will be in the intervention arm for the remainder of their participation regardless of original allocation, or until the time of investigator and/or subject contact in relation to a "high" risk status in an intervention arm subject.
Primary Purpose: Treatment

Arm Intervention/treatment
Placebo Comparator: Observation Arm
Subjects will receive a Reveal LINQ™ Insertable Cardiac Monitor with an investigational ALLEVIATE-HF RAMware download, and will be managed per standard of care for heart failure management without visibility to the heart failure sensor data. Subjects will transition to the intervention arm after 13 months.
 Device: Reveal LINQ™ Insertable Cardiac Monitor with investigational ALLEVIATE-HF RAMware download

Experimental: Intervention Arm
Subjects will receive a Reveal LINQ™ Insertable Cardiac Monitor with an investigational ALLEVIATE-HF RAMware download, and will be managed using an integrated device diagnostic-based risk stratification algorithm combined with a clinical medication plan.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Safety of patient management pathway - Proportion of medication interventions with associated medication intervention related serious adverse events [ Time Frame: Up to 3 years ]
    The proportion of medication interventions with one or more associated medication intervention related SAEs will be evaluated.

  2. Efficacy of patient management pathway - Hierarchical composite of Cardiovascular death, HF events, change in Kansas City Cardiomyopathy Questionnaire and change in six-minute walk test distance [ Time Frame: Follow-up duration at endpoint analysis ranges from a minimum of 7 to a maximum of 13 months ]
    Treatment and Control groups will be compared using the Finkelstein-Schoenfeld method, including subjects with at least one "high" heart failure risk status.


Secondary Outcome Measures :
  1. Safety of Reveal LINQ™ system and procedure - Percentage of subjects experiencing system or procedure related serious adverse events [ Time Frame: Up to 6 months post Reveal LINQ™ device insertion attempt ]
    Freedom from Reveal LINQ™ system and procedure related serious adverse events at 6 months will be evaluated.

  2. Efficacy of patient management pathway - Hierarchical composite of Cardiovascular death, HF events, change in Kansas City Cardiomyopathy Questionnaire, change in six-minute walk test distance, and change in device-measured activity and night heart rate [ Time Frame: Follow-up duration at endpoint analysis ranges from a minimum of 7 to a maximum of 13 months ]
    Treatment and Control groups will be compared using the Finkelstein-Schoenfeld method, including subjects with at least one "high" heart failure risk status.
