Frequently asked questions about Noribogaine

What is Noribogaine?

Noribogaine is an investigational small molecule being developed by AtaiBeckley Inc. (ATAI). It is currently in Phase 1 clinical development for pharmacokinetics, meaning it is being studied to understand how the drug is absorbed, distributed, metabolized, and excreted in the body. It is not yet approved and remains in clinical trials.

What is Noribogaine used for?

Noribogaine is being studied for pharmacokinetics, which is the assessment of how the drug moves through the body. This is an early-stage investigation in healthy volunteers to evaluate the drug's safety and how it is processed. It is not approved for any specific disease or condition.

Who makes Noribogaine?

Noribogaine is being developed by AtaiBeckley Inc., a biopharmaceutical company traded under the ticker symbol ATAI. The company is conducting clinical trials to evaluate the drug's pharmacokinetics in healthy volunteers.

What phase is Noribogaine in?

Noribogaine is in Phase 1 clinical development. A Phase 1 trial has been completed, which studied multiple ascending doses of the drug in healthy volunteers to assess its pharmacokinetics and pharmacodynamics. The drug is investigational and has not been approved by regulatory authorities.

What clinical trials is Noribogaine in?

Noribogaine has one completed Phase 1 clinical trial registered as NCT06480981, titled "Multiple Ascending Dose Noribogaine PK/PD in Healthy Volunteers." This trial enrolled 55 participants in the United Kingdom and was a randomized, double-blind, controlled study involving healthy volunteers aged 18 years and older.

Is Noribogaine the same as ibogaine?

Noribogaine is a distinct compound from ibogaine, though it is related. While ibogaine is a naturally occurring psychoactive substance, noribogaine is a separate small molecule being developed by AtaiBeckley Inc. for its pharmacokinetic properties. The two are not the same drug.
