Frequently asked questions about DITEST

What is DITEST used for?

DITEST is an investigational small molecule being developed for the treatment of male hypogonadism, a condition in which the body does not produce enough testosterone. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

Who makes DITEST?

DITEST is being developed by Neurocrine Biosciences, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol NBIX. The company is conducting clinical research to evaluate the safety and efficacy of DITEST in men with hypogonadism.

What phase is DITEST in?

DITEST is in Phase 1 clinical development. One Phase 1 trial has been completed, involving 25 participants. DITEST remains an investigational drug and is not yet approved for commercial use.

What clinical trials is DITEST in?

DITEST has one completed clinical trial, NCT02966652, titled 'Study to Compare DITEST to Testosterone Undecanoate in Adult Men With Hypogonadism.' This Phase 1 study enrolled 25 adult men in the United Kingdom and was active-controlled, comparing DITEST to an existing testosterone therapy.

Is DITEST the same as testosterone undecanoate?

No, DITEST is a distinct investigational drug. In clinical trial NCT02966652, DITEST was compared against testosterone undecanoate as an active control, meaning the two are different treatments being evaluated for the same condition, male hypogonadism.
