November 14, 2013 updated by: Anthony Mathur, Barts & The London NHS Trust

Randomised Controlled Trial to Compare the Effects of G-CSF (Granocyte™) and Autologous Bone Marrow Progenitor Cells on Quality of Life and Left Ventricular Function in Patients With Idiopathic Dilated Cardiomyopathy

A randomised, double-blind, placebo-controlled trial to evaluate the role of intracoronary injection of progenitor cells compared to placebo injection in patients with Dilated Cardiomyopathy who have been pre-treated with G-CSF (Granocyte™) injections for 5 days, and patients treated with a 5 day course of G-CSF (Granocyte™) injection only compared to placebo injection

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Peripheral
Half the patients will be randomised to the non-interventional part of the trial. In this subgroup of patients will be randomised 1:1 to 5 day course of subcutaneous placebo injections or a 5 day course of G-CSF(Granocyte™) subcutaneous injections
Drug: granulocyte colony stimulating factor (GCSF)
10mcg/kg per day 5 days
Other Names:
  • Lenograstim, Granocyte™, Chugai Pharma UK, Limited
Experimental: Interventional arm
In the subgroup of the interventional arm patients will be randomised 1:1 to receive a 5 day course of subcutaneous G-CSF (Granocyte™) injections and bone marrow aspiration at day 5, they will then receive either stem cells or placebo via intracoronary injection
Procedure: bone marrow mononuclear cells
intra coronary injection of stem cells or placebo

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.

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.
