Tonix Pharmaceuticals dosed first participant in Phase 1 TNX-1900 intranasal oxytocin study; trial measures trigeminal neurovascular reactivity in healthy female volunteers

Tonix reported that the first participant was dosed in a Phase 1 investigator-initiated pharmacodynamic study of TNX-1900, an intranasal potentiated oxytocin drug-device combination being evaluated for potential use in migraine and craniofacial pain.
The study will assess trigeminal nerve-mediated forehead vasodilation by measuring skin blood flow responses to capsaicin and electrical stimulation using Laser Speckle Contrast Imaging.
No clinical results were presented, and the company said results from the study will be used to guide future development of TNX-1900.
