Change from Baseline in Beck Depression Inventory (BDI)
28 days

The minimum possible Beck Depression Inventory (BDI) score is 0, and the maximum score is 63. This score is determined by summing the ratings from the 21 questions, with each question scoring from 0 to 3, indicating the severity of depressive symptoms over the past two weeks. Lower score means less depression

Change from Baseline in Columbia Suicide Severity Rating Scale (C-SSRS)
28 days

The Columbia-Suicide Severity Rating Scale (C-SSRS) does not have a single minimum or maximum score, as it is not a traditional cumulative-score test. Instead, it uses a series of "yes" or "no" questions to place an individual into distinct categories of risk based on their specific responses. Lower score means less suicidal ideation.

Pharmacokinetic Clearance (CL)
28 days

Pharmacokinetic clearance (\\(CL\\)) is a quantitative measure of how efficiently the body removes a drug from the bloodstream. It is defined as the volume of plasma from which a drug is completely and irreversibly removed per unit of time and is typically expressed in units like milliliters per minute (mL/min) or liters per hour (L/h).

Frequently asked questions about ANEB-001

What is ANEB-001 used for?

ANEB-001 is being developed for acute cannabinoid intoxication, a condition caused by excessive exposure to THC, the psychoactive component of cannabis. It is an investigational small molecule that has been studied in a Phase 2 human trial in the Netherlands. It is not approved for commercial use.

What does ANEB-001 target?

ANEB-001 targets the CB1 receptor, the cannabinoid receptor in the brain that mediates the psychoactive effects of THC. ANEB-001 is a small molecule CB1 antagonist, meaning it is designed to block this receptor. Blocking CB1 is the proposed approach for counteracting the effects of acute cannabinoid intoxication.

Who is developing ANEB-001?

ANEB-001 is being developed by Anebulo Pharmaceuticals, Inc., which trades on the Nasdaq under the ticker ANEB. The company is advancing the compound as a potential treatment for acute cannabinoid intoxication.

What phase is ANEB-001 in?

ANEB-001 is in Phase 2 clinical development. Its single reported trial, NCT05282797, was a Phase 2 study that has been completed. ANEB-001 is investigational and has not been approved by the FDA or any other regulatory agency for acute cannabinoid intoxication.

What clinical trials is ANEB-001 in?

ANEB-001 has been studied in one clinical trial, NCT05282797, titled "Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of CB1 Antagonist ANEB-001 in a THC Challenge Test." The Phase 2 trial enrolled 154 participants in the Netherlands, was randomized, double-blind, and placebo-controlled, and has been completed.
