Nobilis Therapeutics Announces FDA Clearance of IND to Commence Phase 2b Trial of NBTX-001 Inhaler for Treatment of Posttraumatic Stress Disorder

Innovative and safe approach to PTSD treatment will be evaluated in a randomized 190-patient clinical trial.

Nobilis Therapeutics, a clinical stage biotechnology company focused on development of treatments for psychiatric and neurodegenerative disorders, announced today that the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for NBTX-001 Inhaler, allowing the Company to initiate its Phase 2b trial for the treatment of patients with Posttraumatic Stress Disorder (PTSD).

“FDA clearance of the IND for NBTX-001 drug-device combination signifies a critical milestone for Nobilis Therapeutics, as it validates its novel approach to treatment of PTSD” said Dr. Vlad Bogin, Company’s Founder and Chief Executive Officer. “Patients with this devastating illness suffer from severely depressed quality of life, deterioration of marital and family relationships, substance abuse and suicidality. Our clinical program is aimed to address not just the symptoms, but the pathophysiology of PTSD.”

Dr. Kerry Ressler, MD, PhD, Professor of Psychiatry at Harvard Medical School, CSO, James and Patricia Poitras Chair in Psychiatry at McLean Hospital, and a Principle investigator of the trial stated: “I am very excited to be helping to lead the NBTX-001 Inhaler trial. I believe that the drug’s competitive inhibition of NMDA receptors, that appears to block trauma memory reconsolidation, may represent an important advance in the treatment of PTSD, a disease with tremendous unmet need for effective medicines.”

NBTX-001 will be a prospective, multicenter, randomized, double-blinded, placebo-controlled phase 2b study that will enroll 190 patients in approximately 25 sites in the United States. The primary endpoint of the study is the mean change from baseline in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) score.

About Posttraumatic Stress Disorder 
Posttraumatic Stress Disorder is a devastating psychiatric condition associated with tremendous emotional and financial costs to the health care system. It is estimated that approximately 6.1% of Americans will suffer from PTSD at one point in their lives, with significantly higher proportions in war veterans suffering from PTSD (approximately 12% to 30%).

Currently the main treatment interventions for PTSD include psychotropic medications and/or psychotherapy. The selective serotonin reuptake inhibitor (SSRI) antidepressants, sertraline and paroxetine, are the only US Food and Drug Administration (FDA) approved medications for the condition that show limited clinical improvement in PTSD sufferers. National Center for PTSD (NCPTSD) treatment guideline recommends Exposure Therapy as one of the most robust treatments. However, although it has shown to be efficacious for treatment of PTSD, a recent randomized clinical study in 370 military personnel with PTSD showed relatively modest reductions in PTSD symptom severity.

PTSD remains a disease with tremendous unmet need currently with only limited effective treatments.
