SAN DIEGO and BURNABY, British Columbia, Dec. 2, 2019 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) and Xenon Pharmaceuticals Inc. (Nasdaq: XENE) announced a license and collaboration agreement to develop first-in-class treatments for epilepsy.
Neurocrine Biosciences gains an exclusive license to XEN901, a clinical stage selective Nav1.6 sodium channel inhibitor with potential in SCN8A developmental and epileptic encephalopathy (SCN8A-DEE) and other forms of epilepsy, including focal epilepsy. In addition, Neurocrine Biosciences gains an exclusive license to pre-clinical compounds for development, including selective Nav1.6 inhibitors and dual Nav1.2/1.6 inhibitors. The agreement also includes a multi-year research collaboration to discover, identify and develop additional novel Nav1.6 and Nav1.2/1.6 inhibitors.
"We are excited to enter into this agreement with Xenon and leverage their expertise in precision medicine drug discovery to benefit the lives of people with epilepsy and serious neurological disorders," said Kevin Gorman, Ph.D., Chief Executive Officer of Neurocrine Biosciences. "The agreement with Xenon strengthens Neurocrine Biosciences' diverse and growing pipeline and reinforces our long-term commitment of becoming a leading neuroscience-focused biopharmaceutical company."
"With its proven expertise in developing and commercializing treatments for neurological disorders, we believe Neurocrine Biosciences is an ideal partner to maximize the potential value of XEN901 for patients," said Dr. Simon Pimstone, Chief Executive Officer of Xenon. "Importantly, this collaboration represents a significant investment in XEN901 and Xenon's earlier-stage Nav1.6 and Nav1.2/1.6 inhibitor programs and allows for a broader development of these promising compounds than we could accomplish independently. Furthermore, the additional capital from this transaction will support our efforts to advance and expand our proprietary pipeline."
License and Collaboration Details / Financial Terms
Under the terms of the agreement, Neurocrine Biosciences will be responsible for development costs associated with the programs and the agreement will be subject to the following terms:
- Upfront License Payment: Xenon will receive $50 million, including a $30 million upfront payment in cash and a $20 million equity investment by Neurocrine Biosciences at a Xenon per share price of $14.196.
- XEN901 Investigational New Drug (IND) Milestone: Xenon will receive up to $25 million upon the U.S. Food and Drug Administration (FDA) acceptance of an IND for XEN901, with 55% of the amount in the form of an equity investment in Xenon at a 15% premium to Xenon's 30-day trailing volume weighted average price at that time.
- Collaboration Milestones: Xenon may also be entitled to receive up to approximately $1.7 billion in additional development, regulatory and commercial milestone payments related to XEN901 and other licensed Nav1.6 or Nav1.2/1.6 inhibitor products.
- XEN901 Royalties: Xenon will have the right to receive a tiered royalty ranging from the low double-digits to mid-teen percentage in the U.S. and a tiered royalty at slightly lower rates outside the U.S. based upon aggregate global net sales.
- Other Product Royalties: Xenon will have the right to receive a tiered royalty for other Nav1.6 and Nav1.2/1.6 inhibitor products ranging from the mid-single to low double-digits in the U.S. and a tiered royalty at slightly lower rates outside the U.S. based upon aggregate global net sales.
- Xenon Co-Fund Option: Xenon retains an option to co-fund 50% of the U.S. development costs of XEN901 or another product candidate in exchange for increased U.S. royalties, reaching 20% of U.S. net sales at the highest royalty tier for XEN901.
- Funded Collaboration: Neurocrine Biosciences will fund all clinical developments costs associated with the development of product candidates under the collaboration (subject to Xenon's Co-Fund Option) and will also fund a research collaboration up to 3 years with a minimum of 10 FTEs (full time equivalents) at Xenon. Xenon will be responsible for certain pre-clinical and a portion of certain near term manufacturing costs under the collaboration.
Neurocrine Biosciences anticipates filing an IND application with the FDA in the middle of 2020 in order to start a proposed clinical trial for XEN901 in SCN8A-DEE patients.

About XEN901 Program for Epilepsy
XEN901 is a potent, highly selective Nav1.6 sodium channel inhibitor being developed to treat pediatric patients with SCN8A developmental and epileptic encephalopathy (SCN8A-DEE) and other potential indications, including adult focal epilepsy. A Phase 1 clinical trial was completed using a powder-in-capsule formulation of XEN901 in healthy adult subjects. Xenon has developed a pediatric-specific, granule formulation of XEN901, and juvenile toxicology studies to support pediatric development activities have recently been completed.
