Tonix Pharmaceuticals Initiates Phase 1 Study for Migraine Treatment TNX-1900
Event summary
- Tonix Pharmaceuticals dosed the first participant in a Phase 1 study of TNX-1900 (intranasal potentiated oxytocin) for migraine and craniofacial pain on March 26, 2026.
- The study, led by Dr. Antoinette Maassen van den Brink at Erasmus University Medical Center, uses Laser Speckle Contrast Imaging (LSCI) to measure trigeminal neurovascular reactivity.
- TNX-1900 targets a distinct pathway from existing CGRP inhibitors, potentially addressing unmet needs in migraine treatment.
The big picture
Tonix Pharmaceuticals is exploring a novel pathway for migraine treatment with TNX-1900, which targets oxytocin receptors to block CGRP release. This approach differs from existing CGRP inhibitors and could address unmet needs in the migraine market. The Phase 1 study represents an early but critical step in validating this mechanism.
