Treatment Focuses on Brain Glial Cells to Alleviate Persistent PTSD Symptoms
New MAOB Inhibitor Shows Promise in Treating PTSD Symptoms
A recent study has revealed a significant link between dysregulated prefrontal GABA levels and PTSD symptoms, and a newly developed drug called KDS2010 could potentially offer a novel therapeutic approach for PTSD treatment.
KDS2010 is a selective and reversible monoamine oxidase B (MAOB) inhibitor that has shown promising results in preclinical and early clinical trials. The drug works by targeting MAOB in astrocytes, which produce abnormal levels of tonic GABA that suppress presynaptic dopamine signaling and impair the brain's ability to "forget" traumatic memories, a core dysfunction in PTSD.
In PTSD-like mice, increased astrocytic GABA via MAOB in brain regions critical for fear regulation, such as the medial prefrontal cortex (mPFC), leads to excessive tonic inhibition, impairing neural circuits involved in extinguishing fear memories. KDS2010 inhibits MAOB, thereby lowering astrocytic GABA levels, normalizing neural activity, restoring striatal dopamine release, and enabling mice to extinguish fear responses effectively.
The study provides preclinical evidence for this new therapeutic approach using an MAOB inhibitor. The drug's reversibility and selectivity are important because it avoids compensatory enzyme activation that limits long-term efficacy seen with irreversible MAO inhibitors. Preclinical findings in mice are supported by human data showing elevated astrocytic GABA and disrupted cerebral blood flow in PTSD patients, implicating the same mechanism.
Regarding human potential, KDS2010 has passed Phase 1 safety trials in humans and is currently in Phase 2 clinical trials. This progress, combined with its novel mechanism targeting astrocyte-mediated GABA dysregulation rather than traditional serotonin pathways, positions KDS2010 as a promising candidate for future PTSD treatments, especially for patients resistant to existing medications.
In summary, KDS2010 works by modulating astrocyte GABA synthesis through MAOB inhibition, reversing PTSD-like behaviors in mice, and is advancing in human trials with the potential to offer a novel therapeutic avenue for PTSD patients. The findings establish MAOB inhibition as a mechanistically targeted approach to alleviate PTSD symptoms.
