About this study

Official title: Acquisition of Skin Biopsies and Blood Samples From Normal Volunteers and Patients With Benign, Inherited Hematologic Diseases for Research Purposes

The investigators plan to obtain skin and blood samples from healthy volunteers and patients with a benign, inherited hematologic disease to use for research to use homologous recombination to correct β-globin gene mutations in therapeutically useful cells, like autologous induced pluripotent stem cells from sickle cell anemia patients.

Read the detailed description
  • To obtain skin biopsy samples from normal healthy volunteers and patients with a benign, inherited hematologic disease, such as sickle cell anemia, to create induced pluripotent stem cells. Pluripotency will be confirmed by injecting potential iPS cell lines into immunodeficient mice, assessing the ability of each line to cause cystic teratomas in recipient mice.
  • To define the efficiency of homologous recombination in induced pluripotent stem cells derived from skin biopsy samples.
  • To define the efficiency of homologous recombination in human embryonic stem cells using NIH-approved cell lines.
  • To establish the genetic consequences of the derivation of human induced pluripotent cells in normal controls or patients with benign, inherited, hematologic diseases, by genomic analysis, including whole genome sequencing.
  • To establish the genetic consequences of homologous recombination in human induced pluripotent stem cells and embryonic stem cells by genomic analysis, including whole genome sequencing.
  • To obtain blood samples to confirm genetic mutations in patients with an inherited hematologic disease (and to confirm no mutations in healthy volunteers).

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted10 Feb 2009 (estimated)
  2. Study startFeb 2009

Questions about this trial

What is this clinical trial studying?

A study testing Skin biopsy and Blood draw & sample in people with Anemia, Sickle Cell, run by Washington University School of Medicine 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 3 inclusion and 7 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: stopped early, as of the sponsor's last update on 11 Jul 2013. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Key samples protocols will be provided by a collaborator and we were not able to produce IPS lines from human fibroblasts.). Results are not available in the source record.

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?

Obtain skin biopsy samples from normal healthy volunteers and patients with a benign, inherited hematologic disease to created induced pluripotent stem cells (time frame: 1 year). 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 NCT00840567, which also lists 18 linked publications.

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 11 Jul 2013.
