About this study

Official title: Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Efficacy, Safety and Tolerability of Transendocardial Injection of Ixmyelocel-T in Subjects With Heart Failure Due to Ischemic Dilated Cardiomyopathy (IDCM).

This study is designed to assess the efficacy, safety and tolerability of ixmyelocel-T compared to placebo (vehicle control) when administered via transendocardial catheter-based injections to patients with end stage heart failure due to IDCM, who have no reasonable revascularization options (either surgical or percutaneous interventional) likely to provide clinical benefit.

Read the detailed description

The primary objective of this study is to evaluate the efficacy of ixmyelocel-T compared to placebo (vehicle control) on the average per patient number of all-cause deaths, cardiovascular hospital admissions, and unplanned outpatient or emergency department visits to treat acute decompensated heart failure, over the 12 months following administration of investigational product (IP).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Average number of clinical events over 12 months post-treatment.

    The primary endpoint will assess the efficacy of ixmyelocel-T compared to placebo (vehicle control) on the average number of events per patient over 12 months post-treatment in each treatment arm (total number events in each arm/total number of patients in each arm). The events include: all-cause deaths, cardiovascular hospitalizations, and unplanned outpatient or emergency department visits to treat acute decompensated heart failure. The clinical events used in this endpoint will be adjudicated by an independent clinical endpoint committee who are blinded to treatment.

    Measured: 12 Months

Secondary outcomes (7)
  1. The win ratio of the hierarchical occurrence of all-cause deaths/left ventricular assist device (LVAD) implant/heart transplant, cardiovascular hospitalizations, and unplanned outpatient and ED interventions to treat ADHF

    This is a composite end point. This endpoint will be primarily assessed excluding events considered to be related to administration of IP. An analysis including IP administration-related events will also be conducted as part of the sensitivity analyses.

    Measured: 12 Months

  2. Change from baseline to 12 months post-treatment in 6-minute walk test.

    A secondary objective will be to evaluate the changes from baseline to 12 months post-treatment in the distance walked as measured by the 6-minute walk test.

    Measured: 12 Months

  3. Change from baseline to 12 months post-treatment in left ventricular function as evaluated by echocardiography.

    A secondary objective will be to evaluate the change in left ventricular function as measured by echocardiography for left ventricular ejection fraction (LVEF).

    Measured: 12 Months

  4. Change from baseline to 12 months post-treatment in quality of life.

    A secondary objective will be to evaluate the change in quality of life (total score) in patients treated with ixmyelocel-T compared to placebo using the Minnesota Living with Heart Failure Questionnaire.

    Measured: 12 Months

  5. Change from baseline to 12 months post-treatment in NYHA Classification.

    A secondary objective will be to evaluate the change from baseline to Month 12 in NYHA Classification in patients treated with ixmyelocel-T compared to placebo.

    Measured: 12 Months

  6. Percent of patients with adverse events.

    A secondary objective will be to evaluate the overall safety and tolerability of ixmyelocel-T versus placebo in patients with DCM from time of aspiration through 12 months post-treatment/follow-up by % of patients with adverse events.

    Measured: 12 Months

  7. Percent of patients with major adverse cardiac events (MACE).

    A secondary objective will be to evaluate the overall safety and tolerability of ixmyelocel-T versus placebo in patients with DCM by the percentage of patients who experience MACE events. MACE events include: unstable angina requiring hospitalization, myocardial infarction, stroke, worsening heart failure requiring hospitalization, VAD implantation, heart transplant, resuscitated sudden death, and cardiovascular death.

    Measured: 12 Months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ixmyelocel-T in people with Ischemic Dilated Cardiomyopathy (IDCM), run by Vericel Corporation at 36 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 33 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 36 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Average number of clinical events over 12 months post-treatment. (time frame: 12 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01670981, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 May 2021.
