Trial summary

Background: Sickle cell disease (SCD) is caused by a genetic defect that affects how hemoglobin is made. Due to this, people with SCD have abnormally-shaped red blood cells, which can result in poor oxygen transport in the body and increase risk of blood clots. Read more about this study

About this study

Background:

Sickle cell disease (SCD) is caused by a genetic defect that affects how hemoglobin is made. Due to this, people with SCD have abnormally-shaped red blood cells, which can result in poor oxygen transport in the body and increase risk of blood clots. CRISPR Cas9 is a new tool which allows scientists to snip and edit genes in a way that is faster, cheaper, and more precise than other gene-editing tools. Recently, research has been done using CRISPR Cas9 to correct the sickle cell gene in animal models and human cells. Researchers want to understand the views of those with SCD, parents of people with SCD, and the providers of these patients regarding use of CRISPR Cas9 in clinical trials and treatment.

Objectives:

To study the attitudes, beliefs, and opinions of those with SCD, parents of those with SCD, and providers on the use of CRISPR Cas9 gene-editing. An additional purpose of this study is to assess the utility of an educational tool for improving understanding of CRISPR Cas9.

Eligibility:

People ages 18 and older who speak English and either have SCD, are a parent of someone with SCD, or are a physician for people with SCD.

Design:

Participants will be screened via phone. Those with SCD will be screened with data from their SCD genotype.

Participation lasts about 2 hours.

Participants will fill out three surveys.

Participants will watch a video about CRISPR Cas9.

Participants will engage in a focus group session. This will be audiotaped and analyzed.

The data from the survey questions and focus groups may be used for future research. However, all personally identifiable information will be removed before data is shared.

Participants data will be identified with a code number instead of their name.

Participants may be invited to join future studies of SCD.

Read the detailed description

The CRISPR/Cas9 gene-editing technique is taking the scientific research and healthcare community by storm with the promise it holds to cure and ease the burden of debilitating diseases. However, there is limited knowledge regarding the implications of using this type of tool in human research and medicine. Researchers need to understand the viewpoints of patients, their families, and their providers, to ensure that the approach taken towards gene-editing is inclusive and respectful of different interests and concerns. The dialogue, thus far, has been dominated by scientific researchers, physician scientists, ethicists, public health and policy experts. It is important to the advancement of the science to study the patient s perspective about the use of the technology. In addition, parents often play important roles in the decision-making process; in this regard, understanding the views and questions of this group of individuals regarding CRISPR/Cas9 human use is essential. We conduct a qualitative study with a mixed methods component to investigate the knowledge, attitudes and beliefs of patients living with sickle cell disease (SCD), the parents of patients with SCD, and the physicians of this patient population regarding the use of CRISPR/Cas9 technology. The study is designed to measure these three cohorts baseline overall genetic literacy, CRISPR-specific literacy, and general attitudes and beliefs toward gene-editing/CRISPR Cas9(in both somatic and germline cells); to evaluate the utility of an educational tool in improving one s understanding of this innovative technique; and to gauge how attitudes and beliefs toward gene-editing, specifically CRISPR Cas9, perhaps shift or remain intact after the educational video, as well as within a focus group space.

Questions about this trial

What is this clinical trial studying?

An observational study of Sickle Cell Disease, run by National Human Genome Research Institute (NHGRI) 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 15 inclusion and 0 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 9 Feb 2021. 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 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?

Focus group interviews related to attitudes, beliefs, and opinions of those with SCD, parents of those with SCD, and providers on the use of CRISPR Cas9 gene-editing. (time frame: At the day of inclusion). The study lists 2 primary outcomes in all. 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 9 Feb 2021.
