Sickle Cell Thalassemia clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Investigating the Mechanistic Effects of Mitapivat in Subjects With Sickle Cell Disease

Start date: May 9, 2024
Phase:
Study type: Observational

Background: Sickle cell disease (SCD) is an inherited blood disorder. The disease affects the ability of red blood cells to carry oxygen; this in turn can injure organs including the heart, lungs, and kidneys. SCD can lead to serious illness and death. Treatments such as bone marrow transplants and gene therapies can cure SCD, but they are not widely available. Current drug treatments for SCD are not always effective. This natural history study will examine how a study drug (mitapivat) affects red blood cells in people with SCD. Objective: To learn how mitapivat affects red blood cells in people with SCD. Eligibility: People with SCD who are enrolled in the parent study, NIH protocol IRB001565-H. Design: Procedures for this study will be done during visits already scheduled for the parent study. Participants will have additional blood drawn during study visits. The additional amount will be about 3.5 teaspoons. Participants will undergo a test called near infrared spectroscopy (NIRS) up to 9 times. Probes will be placed on their skin. A blood pressure cuff will be placed on their arm. The cuff will be filled with air for up to 5 minutes and then released. Participants may be asked to breathe at a certain rate or to hold their breath during these measurements. NIRS measures oxygen levels, blood flow, and the makeup of skin and muscle. Researchers will draw additional information for this study from participants medical records.
