About this study

Official title: A Phase I/II, Randomized, Placebo-Controlled Study of the Safety and Efficacy of Transendocardial Injection of Autologous Human Cells (Mesenchymal or the Combination of MSC and Cardiac Stem Cells) in Patients With Chronic Ischemic Left Ventricular Dysfunction and Heart Failure Secondary to Myocardial Infarction.

Before initiating the full randomized study, a Pilot Safety Phase will be performed. In this phase the composition of cells administered via the Biosense Webster MyoStar NOGA Injection Catheter System will be tested. The randomized portion of the study will be conducted after a full review of the safety data from the pilot Phase by the Data safety monitoring board.

Following the Pilot Phase of five (5) Fifty (50) patients scheduled to undergo cardiac catheterization and meeting all inclusion/exclusion criteria will be evaluated at baseline.

Patients will be randomized in a 2:2:1 ratio to one of three Treatment Strategies.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Autologous hMSCs, Autologous Human C-Kit CSCs II and Biosense Webster MyoStar NOGA Injection Catheter System in people with Chronic Ischemic Left Ventricular Dysfunction and Myocardial Infarction, run by Joshua M Hare at 1 site in United States.

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 7 inclusion and 23 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The record says: withdrawn, as of the sponsor's last update on 22 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 was withdrawn before enrolling participants, so there are no results.

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?

Incidence of any treatment emergent serious adverse events (TE-SAEs) (time frame: One Month post-catheterization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Oct 2020.
