AstraZeneca and Ionis has closed an agreement to develop and commercialise eplontersen
AstraZeneca has closed a global development and commercialisation agreement with Ionis Pharmaceuticals, Inc. (Ionis) for eplontersen, formerly known as IONIS-TTR-LRX.
The companies will jointly develop and commercialise eplontersen in the US, while AstraZeneca will develop and commercialise it in the rest of the world, except in Latin America.
Financial considerations
Under the terms of the agreement, the upfront payment from AstraZeneca to Ionis is $200m. AstraZeneca will make additional conditional payments of up to $485m following regulatory approvals. It will also pay up to $2.9bn of sales-related milestones based on sales thresholds between $500m and $6bn, plus royalties in the range of low double-digit to mid-twenties percentage depending on the region. The collaboration includes territory-specific development, commercial and medical affairs cost-sharing provisions.
The transaction will be funded with cash and is expected to be neutral to Core earnings in 2021. It will be accounted for as an intangible asset acquisition, recognised initially at the upfront amount, with any potential future milestone payments capitalised into the intangible asset as they are recognised.
Ionis will continue to manufacture and supply eplontersen for the existing clinical studies and process qualification. AstraZeneca will be responsible for commercial supply, with transition timing to be agreed by both parties. AstraZeneca will book all sales generated under the agreement.
The transaction does not impact AstraZeneca’s financial guidance for 2021.
