Frequently asked questions about Tolbutamide

What is Tolbutamide?

Tolbutamide is a small molecule drug being studied in a Phase 1 clinical trial. It is being investigated in healthy subjects as a probe substrate for cytochrome P450 enzymes. The drug is being developed by Corcept Therapeutics Incorporated.

What is Tolbutamide used for?

Tolbutamide is used in a clinical trial to determine the effect of relacorilant on exposure to probe substrates for cytochrome P450s. The study involves healthy subjects and aims to assess how relacorilant affects the metabolism of tolbutamide, which serves as a probe for certain enzymes.

Who makes Tolbutamide?

Tolbutamide is being developed by Corcept Therapeutics Incorporated, a company traded on the stock exchange under the ticker symbol CORT. The company is conducting clinical research on this drug in the United States.

What phase is Tolbutamide in?

Tolbutamide is in Phase 1 clinical development. It is an investigational drug and is not approved for any medical use. The drug is being studied in a completed Phase 1 trial involving healthy volunteers.

What clinical trials is Tolbutamide in?

Tolbutamide is associated with one clinical trial, NCT03457597, titled "Study in Healthy Subjects to Determine the Effect of Relacorilant on Exposure to Probe Substrates for Cytochrome P450s." This Phase 1 trial was completed in the United States and enrolled 27 healthy subjects.
