In 2020, Idorsia entered into a global license agreement with Neurocrine Biosciences for the development and commercialization of ACT-709478, Idorsia’s potent, selective, orally active and brain-penetrating T-type calcium channel blocker, for the treatment of a rare pediatric epilepsy, and a research collaboration to discover, identify and develop additional novel T-type calcium channel blockers.

Show more

In 2019, Neurocrine Biosciences paid a $5 million upfront fee to Idorsia for the option rights to ACT-709478 and a preclinical research collaboration. In May 2020, upon Investigational New Drug (IND) application acceptance by the US Food and Drug Administration (FDA), Neurocrine Biosciences exercised the option to license ACT-709478. The exercise of the option triggered an upfront payment of $45 million in cash from Neurocrine Biosciences to Idorsia. In addition, Neurocrine Biosciences will provide an incremental $7 million in funding to Idorsia as part of the research collaboration to discover, identify and develop additional novel T-type calcium channel blockers.

The agreement is subject to the following terms:

  • ACT-709478 milestones: In addition to the up-front payment, Idorsia may also receive up to $365 million in additional development and regulatory milestone payments. Furthermore, Idorsia may also be entitled to one-time commercial payments based on sales thresholds.
  • ACT-709478 royalties: Idorsia will have the right to receive a tiered royalty ranging from the low double-digits to upper teen percentage in the US and a tiered royalty at slightly lower rates outside the US based upon aggregate global net sales.
  • Preclinical research collaboration: The parties will work together to identify novel T-type channel blockers and explore their use in potential new disease states. Idorsia may be entitled to additional development, regulatory and commercial milestones as well as tiered royalties on annual sales for each product included in the research collaboration.
