QP ExCELs: MultiPole Pacing (MPP) Sub-Study

February 16, 2021 updated by: Biotronik, Inc.
The objective of this MultiPole Pacing (MPP) sub-study of the QP ExCELs study is to demonstrate that the MPP feature is effective by converting a percentage of cardiac resynchronization therapy (CRT) non-responders to responders. The MPP sub-study is a single-arm, multi-center, prospective trial within the ongoing QP ExCELs study (NCT02290028).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Currently enrolled in the ongoing QP ExCELs study
  • Successfully implanted with a BIOTRONIK Ilivia 7 HF-T QP family CRT-D system, or future-marketed CRT-D system with the MPP feature. Successful implantation is defined as having at least two LV pacing vectors with a measured pacing threshold of ≤ 5.0 V @ any pulse width (allowing for a minimum 2.5 V safety margin) without phrenic nerve stimulation at the final programmed pacing output at the time of enrollment into the MPP sub-study.
  • CRT Responder Assessment classification as "Worsened" or "Unchanged"
  • Standard continuous biventricular (BiV) pacing from implant until the 6-Month QP ExCELs follow-up visit. (Implant to 3-Month QP ExCELs follow-up who qualify due to a Heart Failure (HF) hospitalization event)
  • Able to understand the nature of the sub-study and give informed consent
  • Available for an additional follow-up visit specific to the MPP sub-study at the investigational site
  • No evidence of non-compliance to their ongoing commitment in the QP ExCELs study

Exclusion Criteria:

  • Have a life expectancy of less than 6 months
  • Expected to receive heart transplantation or ventricular assist device within 6 months
  • Chronic atrial fibrillation
  • Presence of another life-threatening, underlying illness separate from their cardiac disorder
  • Received MPP pacing prior to enrolment into the MPP sub-study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cardiac Resynchronization Therapy (CRT) Responder Status With the MPP Feature
Time Frame: Enrollment to 6 Months

Count of participants who are classified as "Improved", where responder classification is derived from a clinical composite score (CCS) based on changes in New York Heart Association (NYHA) class, Heart Failure (HF) hospitalization, and cardiovascular death.

Responder classification at 6 months (evaluated compared to MPP Enrollment Visit) :

  • "Improved"

    • No HF hospitalization or cardiovascular death, AND
    • NYHA class is improved

  • "Unchanged"

    • No HF hospitalization or cardiovascular death, AND
    • NYHA class is unchanged

  • "Worsened"

    • HF hospitalization or cardiovascular death has occurred, OR
    • NYHA class is worsened
Enrollment to 6 Months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Without MPP System Related Adverse Events Requiring Additional Invasive Intervention to Resolve at 6 Months.
Time Frame: Enrollment to 6 Months
Evaluate adverse events that require additional invasive intervention to resolve specifically related to the MPP feature. These adverse events include any software issues related to MPP programming or any adverse event that occurs while MPP is enabled and that may be attributed to the use of the MPP feature. Outcome was evaluated as an adverse event free-rate (AEFR).
Enrollment to 6 Months
Clinical Composite Score (CCS) + Patient Global Assessment (PGA) Responder Status Utilizing a Modified CCS That Incorporates the PGA
Time Frame: Enrollment to 6 Months

Evaluate a modified CCS, determining a responder classification based on changes in NYHA class, PGA, HF hospitalization, and cardiovascular death, where the PGA will ask participantss to assess how their overall status has changed since prior to receiving CRT therapy (markedly better, better, unchanged, worse, markedly worse).

Modified responder classification (CCS + PGA) at 6 months (evaluated compared to MPP Enrollment Visit):

  • "Improved"

    • No HF hospitalization or cardiovascular death, AND
    • Neither NYHA class is worsened or PGA is worsened ("worse" or "markedly worse"), AND
    • NYHA class is improved or PGA is improved ("better" or "markedly better")

  • "Unchanged"

    • No HF hospitalization or cardiovascular death, AND
    • NYHA class is unchanged, AND
    • PGA is unchanged ("unchanged")

  • "Worsened"

    • HF hospitalization or cardiovascular death has occurred, OR
    • NYHA class is worsened or PGA is worsened ("worse" or "markedly worse")
Enrollment to 6 Months
CCS Responder Status Utilizing an Expanded Responder Classification
Time Frame: Enrollment to 6 Months

Evaluate a modified CCS with an expanded responder classification where "Improved" and "Unchanged" are considered responders.

Responder classification at 6 months (evaluated compared to MPP Enrollment Visit) :

  • "Improved"

    • No HF hospitalization or cardiovascular death, AND
    • NYHA class is improved

  • "Unchanged"

    • No HF hospitalization or cardiovascular death, AND
    • NYHA class is unchanged

  • "Worsened"

    • HF hospitalization or cardiovascular death has occurred, OR
    • NYHA class is worsened
