Vitamin B1 movement in people with and without an active OCT1 transporter
This study checks how vitamin B1 (thiamin) moves through the body in healthy people. It compares two groups: those with a normal OCT1 liver transporter and those with a less active one. The goal is to see if genetics affect how your body handles vitamin B1.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 18 and 50 years old
- You need to have a known OCT1 gene type (either a good transporter or a poor transporter)
- You should be generally healthy or have only mild, well-controlled conditions like allergies or high blood pressure
- You can take up to 3 prescription medications that don't interact with OCT1
- You cannot be pregnant, breastfeeding, or taking regular vitamin B1 supplements without a 48-hour break before visits

This phase 1 study tests an experimental drug called TIX100 in healthy volunteers to check its safety and how the body processes it. The results will help determine if the drug can be studied in future trials for conditions like obesity or metabolic disorders.
This study tests how a new medicine, BI 3000202, is absorbed into the blood. It includes people with different levels of liver function (normal, mild, moderate, or severe) to see if liver problems affect how the medicine works.
This study tests a new investigational drug called TBN in healthy volunteers to see if it is safe and how the body processes it. It's an early phase trial, so it's not about treating a disease but about understanding the drug's effects.
This Phase 2 study tests whether taking thiamine and biotin together can improve symptoms in people with Huntington’s disease. It looks especially at people with confirmed genetic Huntington’s disease and certain types of movement and/or mood symptoms.
This trial tests whether taking vitamin B1 can help people with familial adenomatous polyposis (FAP) reduce the number of polyps in their colon or rectum. It is designed for people who still have most of their bowel and have more than 10 polyps.
This study tests whether giving vitamin B1 (thiamine) to people who drink heavily can reduce alcohol-related brain injury. It may help protect memory and thinking if you are currently drinking a lot.
