Trial summary

Background: Sickle cell disease is an inherited blood disorder. People with this disease have a problem with their hemoglobin. That is a protein in red blood cells that carries oxygen in the body. Some people with this disease are enrolled in research at NIH. Read more about this study

About this study

Background:

Sickle cell disease is an inherited blood disorder. People with this disease have a problem with their hemoglobin. That is a protein in red blood cells that carries oxygen in the body. Some people with this disease are enrolled in research at NIH. Researchers want to learn more about the thoughts and opinions of those people. This may improve the way researchers explain clinical studies, risks, and benefits to people with the disease.

Objective:

To learn about the motivations, decisions, and experiences in clinical research of people with sickle cell disease.

Eligibility:

Adults ages 18 and older who have sickle cell disease. They must be in an NIH study on this condition. They must have been invited to join either a gene therapy or peripheral blood stem cell transplantation study.

Design:

Participants will have 1 interview. It will be done in a quiet room in the NIH Clinical Center or by video call. It will take about 60 minutes.

The interview will be audio-recorded if the participant agrees.

Participants will be asked about:

  • Their experiences with and thoughts on sickle cell disease
  • Their decision to participate in clinical research
  • Factors that may have affected their decision to participate. These may include family, disease history, or faith.

Participants may complete a few brief questionnaires.

Read the detailed description

Clinical trials testing potentially curative interventions for sickle cell disease - such as gene therapy (GT) or peripheral blood stem cell transplantation (PBSCT) - have created a novel opportunity for patients with sickle cell disease, for whom standard therapies can only manage but not cure their conditions. But some of these experimental interventions may pose risk of significant adverse events. As the development of these interventions create a new decision-making situation for persons with longstanding diseases, these trials raise questions about the expectations and decision- making process of patients considering and/or participating in them. Given the longstanding debate in the bioethics literature about whether patients expressions of desire for benefit are (1) evidence of false hopes or poor understanding of risks and benefits, or, instead (2) expressions of natural optimism compatible with valid informed consent, these patients present an opportunity to learn about how they make their participation decisions which in turn could inform this longstanding debate.

This study aims to explore the expectations, understanding, motivations, and decision-making of patients with sickle cell disease who have either chosen or declined to enroll in research studies testing experimental interventions. The aim is to better understand how these patients understand the research study, assess risks and benefits at the time of enrollment, make decisions, and react to their health outcomes. As faith and religion are known to play an important part in the lives of persons with sickle cell disease, we will also explore the role of religion and faith in sickle cell patients decision-making and retrospective perspective on their decision.

Primary Hypothesis:

This is a descriptive, explorative study. It may generate hypotheses for future studies.

Purpose of the Study Protocol:

To describe how patients with sickle cell disease understand and make decisions about participating in gene therapy (GT) or peripheral blood stem cell transplantation (PBSCT) clinical trials to shed light about the ethically salient issues regarding enrollment and participation in high- risk, high-reward clinical trials. This information may inform practices around the informed consent process and help researchers better understand the role of family and religion/faith in clinical research decision making.

Questions about this trial

What is this clinical trial studying?

An observational study of Sickle Cell Disease, run by National Institutes of Health Clinical Center (CC) 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 9 inclusion and 4 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 1 Sep 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. 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?

Expectations, understanding and motivations for enrollment (time frame: Before or after enrollment in PBSCT or GT trial, but after decision made). 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 NCT03709303, which also lists 3 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 1 Sep 2020.
