简要总结
The primary objective of this study is to evaluate the safety and tolerability of the dietary supplement, nicotinamide mononucleotide (NMN), in individuals with dehydrodolichol diphosphate synthase congenital disorder of glycosylation (DHDDS-CDG). This will to contribute to knowledge that will allow healthcare providers to make informed decisions about recommending this dietary supplement in this population.
详细描述
This is a small cohort, off label treatment study assessing the safety, and tolerability of the over-the-counter supplement, nicotinamide mononucleotide (NMN) in individuals with heterozygous DHDDS-CDG. There is no treatment currently available for this progressive disease and there is evidence that this supplement may be a viable supportive therapy. This study will assess the safety and tolerability of this supplement, as well as examine NMN's effect on clinical manifestations of DHDDS-CDG, including gait abnormalities and hand tremor. This phase 1, open-label study will have a 4 week run-in period, a treatment period of 6 months during which the participants will take 250 mg NMN daily, and an optional extension period of 6 more months. Study assessments will involve physician assessments, lab tests, physical exams, vital signs, height/weight measurements, participant goal-setting, and tests to assess gait performance and hand tremor.
