NCT04000165 ↗	Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Escalating Multiple Oral Doses of AG-348 in Subjects With Stable Sickle Cell Disease	Completed	National Heart, Lung, and Blood Institute (NHLBI)	Early Phase 1	2019-07-11	Background: Sickle Cell Disease (SCD) is an inherited blood disorder. People with SCD have abnormal hemoglobin in their red blood cells. Researchers are investigating the safety and efficacy of an investigational medicine called AG-348 (mitapivat sulfate) to determine if it will help people with SCD. Objective: To test the tolerability and safety of AG-348 in people with SCD. Eligibility: People ages 18 and older with SCD. Design: Participants will have 8 visits over approximately 14 weeks. At the first visit participants will be screened with a medical history; a physical exam; and blood, urine, and heart tests. At the following 5 visits participants will stay at the clinic for 1 night each. Participants will take study drug in increasing doses upto visit 6, after which the drug will be tapered off. All visits will include physical exam, blood, and urine tests. The last visit will occur 4 weeks after stopping the drug and also includes a heart test. Participants will provide DNA from the blood samples they provide. The DNA will be tested for an inherited gene that can cause differences in response to the study drug. Researchers may also test other genes to see if they can find any genes that interact with SCD.
