About PUR3100
PUR3100 is an orally inhaled formulation of dihydroergotamine (DHE) engineered with iSPERSE™ for the treatment of acute migraine. The Phase 1 PUR3100 trial results were presented at the 65th Annual Meeting of the American Headache society in June 2023. Over 38 million patients suffer from migraine in the United States and there is currently no orally inhaled DHE treatment option for patients.

About iSPERSE™ Technology
Our innovative particle engineering technology creates dry powder, which solves limitations of conventional inhaled technologies and expands the universe of inhalable drug therapies. iSPERSE™ is a proprietary technology that allows a broad range of drugs to be formulated as small, dense, and dispersible particles for highly efficient drug delivery and deep penetration into the lungs. iSPERSE™ can efficiently deliver small molecules, drug combinations, peptides, proteins, and nucleic acids via the respiratory system for the treatment of both respiratory and non-respiratory diseases.
