Pilot Study of Minocycline (NPL-2003) in Adults With Obsessive-Compulsive Disorder (OCD)

Obsessive-compulsive disorder (OCD) is a common psychiatric illness that affects up to 2-3% of the population. People with OCD experience anxiety-provoking, intrusive thoughts, known as obsessions, and feel compelled to perform repetitive behaviors, or compulsions. The only medications proven effective for OCD are serotonin reuptake inhibitors (SRIs), but even with SRI treatment, most patients continue to experience significant OCD symptoms, impaired functioning, and diminished quality of life. Recent evidence suggest that a different neurotransmitter, glutamate, may contribute to the symptoms in OCD. Medications that target glutamate hold promise for ameliorating symptoms for those patients continuing to suffer from OCD. In this study we are recruiting patients to receive the drug NPL-2003, which is thought to modulate the neurotransmitter glutamate, added to whatever other OCD medications they are taking in a 12-week open label study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Patients Who Met and Exceeded Response Criteria of Yale-Brown Obsessive-Compulsive Scale	Patients given YBOCS (Yale Brown Obsessive-Compulsive Scale), a gold standard measure of obsessions and compulsions. For the YBOCS the minimum units are 0 and Maximum units on the total scale are 40. The higher the number on the YBOCS, the more severe the symptoms. Response was defined as at least a 30% reduction on the YBOCS.	12 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Patients That Met Response Criteria for the Hamilton Depression Rating Scale.	Patients given HAM-D (Hamilton Depression Scale), a measure of depressive symptoms. For the HAM-D the minimum units are 0 and Maximum units on the total scale are 50. The higher the number on the HAM-D, the more severe the symptoms. Response was defined as at least a 30% reduction on the HAM-D.	12 weeks
