Collaborative Arrangements and Licensing Agreements [Abstract] |
Collaborative Arrangements and Licensing Agreements | 6. Collaborative Arrangements and Licensing Agreements Below, we have included our collaborations with substantive changes during the first three months of 2020 from those included in Note 6 of our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019. Strategic Partnership Biogen We have several strategic collaborations with Biogen focused on using antisense technology to advance the treatment of neurological disorders. These collaborations combine our expertise in creating antisense medicines with Biogen’s expertise in developing therapies for neurological disorders. We developed and licensed to Biogen SPINRAZA, our approved medicine to treat people with spinal muscular atrophy, or SMA. In December 2017, we entered into a collaboration with Biogen to identify new antisense medicines for the treatment of SMA. We and Biogen are currently developing eight medicines to treat neurodegenerative diseases under these collaborations, including medicines to treat people with ALS, Alzheimer’s disease and Parkinson’s disease. In addition to these medicines, our collaborations with Biogen include a substantial research pipeline that addresses a broad range of neurological diseases. From inception through March 2020, we have received more than $2.5 billion from our Biogen collaborations. During the three months ended March 31, 2020 and 2019, we earned the following revenue from our relationship with Biogen (in millions, except percentage amounts):
|  | Three Months Ended March 31, |
|  | 2020 |  |  | 2019 |
SPINRAZA royalties (commercial revenue) |  | $ | 66.0 |  |  | $ | 59.7 |
R&D revenue |  |  | 21.4 |  |  |  | 24.5 |
Total revenue from our relationship with Biogen |  | $ | 87.4 |  |  | $ | 84.2 |
Percentage of total revenue |  |  | 66 | % |  |  | 28 | %
2012 Neurology Collaboration In the first quarter of 2020, we achieved a $7.5 million milestone payment from Biogen when we advanced IONIS-MAPTRx in development. This milestone payment did not create a new performance obligation because it is part of our performance obligation to conduct development of IONIS-MAPTRx. Therefore, we included the $7.5 million milestone payment in our transaction price for our IONIS-MAPTRx development performance obligation. We are recognizing revenue for our IONIS-MAPTRx development performance obligation based on the percentage of completion. From inception through March 2020, we have included $45.0 million in the transaction price for our IONIS-MAPTRx development performance obligation. We currently estimate we will satisfy our performance obligation in 2022. During the first three months of 2020, we did not have any changes to our performance obligations or the timing in which we expect to recognize revenue under our Biogen collaborations, except as noted above. Our condensed consolidated balance sheet at March 31, 2020 and December 31, 2019 included deferred revenue of $512.3 million and $525.8 million, respectively, related to our relationship with Biogen. Research, Development and Commercialization Partners AstraZeneca We have two collaborations with AstraZeneca, one focused on the treatment of cardiovascular, renal and metabolic diseases and a second focused on the treatment of oncology diseases. We and AstraZeneca are currently developing several medicines under these collaborations, including medicines to treat people with cardiovascular disease, a genetically associated form of kidney disease, nonalcoholic steatohepatitis, or NASH and cancer. From inception through March 2020, we have received more than $300 million from our AstraZeneca collaborations. During the three months ended March 31, 2020 and 2019, we earned the following revenue from our relationship with AstraZeneca (in millions, except percentage amounts):
|  | Three Months Ended March 31, |
|  | 2020 |  |  | 2019 |
R&D revenue |  | $ | 13.8 |  |  | $ | 4.0 |
Percentage of total revenue |  |  | 10 | % |  |  | 1 | %
Our condensed consolidated balance sheet at March 31, 2020 and December 31, 2019 included deferred revenue of $21.3 million and $25.0 million, respectively, related to our relationship with AstraZeneca. During the first three months of 2020, we did not have any changes to our performance obligations or the timing in which we expect to recognize revenue under our AstraZeneca collaborations, except as noted below. Cardiovascular, Renal and Metabolic Diseases Collaboration In the first quarter of 2020, we achieved a $10 million milestone payment from AstraZeneca when AstraZeneca advanced ION532, a medicine targeting APOL1 for the treatment of kidney disease, in development. We concluded that this milestone payment was not related to our R&D services performance obligation. Therefore, we recognized the $10 million milestone payment in full in the first quarter of 2020 because we did not have any performance obligations related to this payment. We will achieve the next payment of up to $30 million if AstraZeneca licenses a medicine under this collaboration.
