Alnylam has a license to use our IP to develop and commercialize products and may only grant access to our LNP technology to its partners if it is part of a product sublicense. Alnylam’s license rights are limited to patents that we have filed, or that claim priority to a patent that was filed, before April 15, 2010. Alnylam does not have rights to our patents filed after April 15, 2010 unless they claim priority to a patent filed before that date. Alnylam will pay us low single digit royalties as Alnylam’s LNP-enabled products are commercialized.
In July 2015, Alnylam announced initiation of a Phase III open label OLE study with patisiran (APOLLO-OLE) to evaluate the long-term safety and tolerability of patisiran in ATTR amyloidosis patients with FAP who were previously enrolled in the APOLLO Phase III study. In September 2015, Alnylam reported evidence of reduced pathogenic, misfolded TTR monomers and oligomers in TTR-mediated amyloidosis patients with FAP, and in November 2015 it reported that patisiran demonstrates continued evidence for potential halting of neuropathy progression and improvement in nerve fiber density in patients with FAP. New Drug Application filing for this program is expected in 2017. The patisiran program represents the most clinically advanced application of our LNP delivery technology. Furthermore, Alnylam’s results demonstrate that multi-dosing with our LNP has been well-tolerated with treatments out to 25 months. Results from this study are expected in mid-2017.
