Impel NeuroPharma said today that it raised $67.5 million in a Series D financing round, with investments from KKR, Norwest Venture Partners, Vivo Capital, 5Am Ventures and venBio Partners.
The Seattle-based company plans to use the round’s proceeds to support clinical development efforts for its intranasal drug-delivery device technology.
Impel’s INP104 product is in a Phase III trial for the treatment of acute migraine headache. The company also has a product in a Phase II trial for the reversal of “off” periods in people with Parkinson’s disease, as well as a product in a Phase I trial for the treatment of acute agitation in bipolar I and schizophrenia disorders.
