Tryp Therapeutics Inc. announced it has submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for its planned Phase 2a clinical trial investigating the effects of psilocybin-assisted psychotherapy in the treatment of patients aged 21+ suffering from Irritable Bowel Syndrome (IBS) at Massachusetts General Hospital (MGH). The planned open label study in collaboration with Harvard Medical School/Mass Massachusetts General Hospital will evaluate the effect of psilocybin- assisted psychotherapy in patients with treatment-resistant IBS who experience chronic abdominal pain and other debilitating gastrointestinal symptoms. Many of these patients also suffer from fibromyalgia, anxiety and fatigue. The primary efficacy endpoint of the study will be improvement in abdominal pain.

The proposed study will also explore changes in brain connectivity and responses to pain at baseline and at four weeks, six months and twelve months post the psychedelic drug sessions, along with numerous other secondary endpoints.
