Study Endpoints

Primary Endpoints

Hamilton Anxiety Rating Scale (HAM-A)
Screening (Day-63 and Day-1), Day 2, Day 8, Day 21, Day 23, Day 29, Day 43, Day 64, Day 85, Day 169, Day 266, and End of Treatment (Day 364)

The HAM-A is a 14-item scale that is used to rate the severity of symptoms of anxiety. Each of the 14 items is defined by a series of symptoms and measures both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). Items are scored from 0 (not present) to 4 (very severe), for a total score ranging from 0 to 56. Scores \<17 indicate mild anxiety, scores of 18 to 24 indicate mild to moderate anxiety, and scores of 25 to 30 or higher indicate moderate to severe anxiety.

Secondary Endpoints

Hamilton Depression Scale (HAM-D)
Screening (Day-63 and Day-1), Day 2, Day 8, Day 21, Day 23, Day 29, Day 43, Day 64, Day 85, Day 169, Day 266, and End of Treatment (Day 364)

Frequently asked questions about CYB004

What is CYB004 used for?

CYB004 is an investigational small molecule being developed for the treatment of Generalized Anxiety Disorder (GAD). It is a N,N-dimethyltryptamine (DMT) analog and is currently in Phase 2 clinical development. The drug is being studied in adults aged 18 years and older with GAD.

What does CYB004 target?

CYB004 is a N,N-dimethyltryptamine (DMT) analog. DMT is a psychedelic compound that acts on serotonin receptors, particularly the 5-HT2A receptor, which is thought to mediate its therapeutic effects in anxiety disorders. However, the specific molecular target of CYB004 has not been disclosed.

Who makes CYB004?

CYB004 is being developed by Cybin Inc., a biopharmaceutical company focused on psychedelic-based therapeutics. Cybin Inc. is publicly traded under the ticker symbol HELP. The company is conducting clinical trials to evaluate CYB004 for the treatment of Generalized Anxiety Disorder.

What phase is CYB004 in?

CYB004 is in Phase 2 clinical development. A Phase 2 study of CYB004 in participants with Generalized Anxiety Disorder has been completed. The drug is investigational and has not been approved by regulatory authorities. Further clinical development may be required to establish its safety and efficacy.

What clinical trials is CYB004 in?

CYB004 has been studied in one clinical trial, identified as NCT06051721. This was a Phase 2, randomized, double-blind, active-controlled study in participants with Generalized Anxiety Disorder. The trial enrolled 36 participants in the United States and has been completed. No active trials are currently listed.

Is CYB004 the same as DMT?

CYB004 is a N,N-dimethyltryptamine (DMT) analog, meaning it is a chemical derivative of DMT. While it is related to DMT, it is a distinct compound being developed by Cybin Inc. for Generalized Anxiety Disorder. The drug is currently in Phase 2 clinical trials and is not the same as DMT itself.
