Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with sickle cell trait, known hemoglobinopathies, or healthy volunteers for control purposes.

Probably not a fit

Patients who are unable to comprehend the investigational nature of the research or those with HIV, Hepatitis B, or Hepatitis C will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to collect blood samples from both healthy individuals and those with unique red blood cell features related to sickle cell disease. The goal is to investigate potential new drug treatments for sickle cell disease by analyzing these samples. Participants will undergo a one- to two-hour outpatient procedure at the National Institutes of Health Clinical Center, where they will donate small volumes of blood for high throughput screening tests. The study focuses on identifying compounds that can inhibit the sickling of red blood cells, which is a critical issue in sickle cell disease.

Why it matters

Potential benefit: If successful, this research could lead to the development of new and more effective treatments for sickle cell disease.

How similar studies have gone: Other studies have shown promise in identifying new treatments for sickle cell disease, but this specific approach of high throughput screening is relatively novel.

Show full inclusion / exclusion criteria
* INCLUSION CRITERIA:
* Patients with sickle cell trait
* Patients with known hemoglobinopathies involving one or two genes for sickle hemoglobin
* Healthy volunteers for control experiments
* Age range: adults greater than or equal to 18 years of age

EXCLUSION CRITERIA:

* Subjects who are unable to comprehend the investigational nature of the laboratory research are ineligible to enroll in this protocol.
* As a safety precaution in handling the blood samples, patients with HIV, Hepatitis B or Hepatitis C will be excluded from the study. HIV, Hepatitis B or Hepatitits C testing will not be done under this study. Participants must be co-enrolled under another NIH protocol where the screening evaluation has been performed.
