Study of ABX-002 for the Adjunctive Treatment of Depressive Episodes Associated With Bipolar Disorder in Adults

Phase 2
Recruiting
Conditions
Bipolar Disorder Depression
Interventions
Registration Number
NCT06869187
Lead Sponsor
Autobahn Therapeutics, Inc.
Brief Summary

The goal of this clinical trial is to learn if ABX-002 added to participants' existing treatment(s) shows effects on brain chemistry that may correlate with antidepressive effects.

This is a single treatment arm, open-label, Phase 2 study of ABX-002 in 30 adults with bipolar depression. Five healthy volunteer participants will also be enrolled and receive no drug treatment, undergoing 2 imaging sessions to confirm instrument and test - retest method reliability control.

For bipolar disorder participants who are experiencing an episode of depression, the study will include 3 study periods:

1. Screening Period of up to 4 weeks

2. 6-week Treatment Period

3. 2-week post dose Safety Follow-up Period.

For healthy volunteers, the study will include 2 study periods:

1. Screening Period of up to 3 weeks

2. Imaging Period of up to 3 weeks.

Primary Outcome Measures
NameTimeMethod
Correlation of change from Baseline in the anterior cingulate cortex (ACC) phosphocreatine/inorganic (PCr/Pi) concentration with percentage change in Hamilton Depression Rating Scale (HAMD)-17Week 6

Utilizing 31P-Magnetic Resonance Spectroscopy (31P-MRS), a magnetic resonance imaging (MRI) method that measures high-energy phosphates in the brain

Correlation of change from baseline in the anterior cingulate cortex (ACC) nucleoside triphosphate/inorganic phosphate (NTP/Pi) concentrations with percentage change in Hamilton Depression Rating Scale (HAMD)-17Week 6

Utilizing 31P-Magnetic Resonance Spectroscopy (31P-MRS), a magnetic resonance imaging (MRI) method that measures high-energy phosphates in the brain

Secondary Outcome Measures
NameTimeMethod
Change from baseline for 17-item Hamilton Rating Scale for Depression (HAMD-17)Weeks 6

HAMD-17 is a clinician-based assessment of depressive symptoms. Higher scores indicate worse symptoms. A score of 0-9 is generally accepted to be within the normal range (or in clinical remission), while a score of greater than 17 indicates moderate to severe depression symptoms.

Change from baseline for 6-item Hamilton Rating Scale for Depression (HAMD-6)Weeks 6

Six-item scale used to assess the core symptoms of depression. HAMD-6 is a shorter version of HAMD-17. The higher the total score the more severe the depression.

Change from baseline for 29-item Hamilton Rating Scale for Depression (HAMD-29)Weeks 6

HAMD-29 is a clinician-based assessment of depressive symptoms. Higher scores indicate worse symptoms. A score of 0-7 is generally accepted as not depressed, 8-16 indicates mild depression, 17-23 indicates moderate depression, and 24 and above indicates severe depression.
