NCT04786548

Brief Summary

The goal of this study is to examine whether measurements of inflammation from brain scanning and blood tests can predict how much benefit patients with obsessive-compulsive disorder (OCD) will have from treatment with an anti-inflammatory medication, celecoxib, when adding to ongoing medication-based treatment for OCD.

Outcome Measures

Primary Outcomes (1)

  • Yale-Brown Obsessive Compulsive Scale

    The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is a clinician-administered interview that measures the presence and severity of symptoms of Obsessive-Compulsive Disorder. It consists of 10 questions with scores ranging from 0 to 4, with a possible score ranging from 0 to 40. The primary measure of clinical improvement in this study is the Week 8 YBOCS score. In statistical models, we will co-vary for the Week 0 YBOCS score to account for baseline symptoms severity, but the Week 8 value is the primary outcome.

Study Arms (1)

Celecoxib Treatment

EXPERIMENTAL

Patients will receive standardized pharmacotherapy with celecoxib 100mg twice daily for the first week, and will then, if well-tolerated, will be increased to 200mg twice daily for the next seven weeks. Visits with the study psychiatrist will occur weekly for the first four weeks, and biweekly thereafter until week 8, which will be conducted remotely in general, although they may be conducted in-person as clinically warranted and may be conducted in person on the days of other in-person visits. If individuals experience significant side-effects from a given dose, the treating physician may lower the medication dose according to clinical judgment; if side-effects are intolerable, we will discontinue the research procedures and advance to open clinical treatment

Drug: Celecoxib

Interventions

Patients will receive standardized pharmacotherapy with celecoxib 100mg twice daily for the first week, and will then, if well-tolerated, will be increased to 200mg twice daily for the next seven weeks.
