Официальное название
Pilot Study of Quercetin Patients With Dyskeratosis Congenita/Telomere Biology Disorders
Обзор
The purpose of this study is to see if a vitamin-like substance called quercetin is safe for people who have a rare condition called Dyskeratosis congenita (DC) or telomere biology disorders (TBD).
Подробное описание
The purpose of this study is to see if a vitamin-like substance called quercetin is safe for people who have a rare condition called Dyskeratosis congenita (DC) or telomere biology disorders (TBD). This study is a single arm, open-label pilot study. There is no randomization. This study will enroll approximately 12 patients with DC/TBD who will be treated with quercetin for 24 weeks.
Вмешательства
- Препарат Quercetin
Quercetin (3, 30, 40, 5, 7-pentahydroxyflavone) is a naturally occurring antioxidant that belongs to a group of polyphenolic compounds known as flavonoids. Quercetin is routinely available as an over-the-counter product due to it being a nutritional supplement. However, for the purpose of the study, it will be purchased in the powder form from PCCA (supplied as 96% quercetin dihydrate) and stored and distributed by the investigational pharmacy at CCHMC using standard operational procedures.
