Deferred revenue, description			Under the LianBio License Agreement, in order to evaluate the transaction price for purposes of ASC 606, the Company determined that the upfront payment of $12.0 million and the reimbursable cost of the clinical supply of LYR-210 constitute the entirety of the consideration to be included in the transaction price as of the outset of the arrangement, which was allocated to the two performance obligations as follows: $8.4 million to the Combined Performance Obligation and $3.6 million to the Development Activities Performance Obligation. In February 2022, the Company received $5.0 million upon achievement of the first of the development milestones related to dosing its first patient and the transaction price was adjusted by $5.0 million which was allocated to the two performance obligations as follows: $3.5 million to the Combined Performance Obligation and $1.5 million to the Development Activities Performance Obligation. The remaining potential milestone payments that the Company is eligible to receive were excluded from the transaction price as of December 31, 2023, as all milestone amounts were fully constrained based on the probability of achievement.
