NCT ID: NCT03746106 Completed - Thiamine Deficiency Clinical Trials

The Effect of SLC19A3 Inhibition on the Pharmacokinetics of Thiamine

Start date: January 28, 2019
Phase: Phase 4
Study type: Interventional

In Part 1, subjects will be administered thiamine, thiamine with metformin, and thiamine with trimethoprim. Part 2 will expand on Part 1 and subjects will be administered thiamine and thiamine with trimethoprim. The goal is to determine whether taking a drug and a vitamin together affects the body's ability to absorb, distribute, and eliminate thiamine (Vitamin B1).

NCT ID: NCT03466528 Completed - Alcohol Withdrawal Clinical Trials

Alcohol: Thiamine and or Magnesium 1

AToM1
Start date: December 16, 2016
Phase: Phase 2/Phase 3
Study type: Interventional

Patients who suffer Alcohol Use Disorder (AUD) have a 30-80% incidence of thiamine deficiency causing Wernicke's Encephalopathy (WE). Intravenous (IV) thiamine replacement is standard practice in the treatment of alcoholic patients presenting to the Accident & Emergency (A&E) department, however routine co-supplementation with magnesium (administered IV as magnesium sulphate ), which is required as a co-factor for thiamine in some metabolic processes, e. g. on the activity of the enzyme transketolase in red blood cells, is not routine practice in the treatment of these patients. Without correction of concomitant magnesium deficiency there may be impaired utilisation of thiamine resulting in a failure to treat WE. This study is designed to determine if administration of magnesium to AUD patients affects red cell transketolasae and serum lactate concentrations by itself, or only acts to increase the effect of thiamine on the activity of this enzyme.
