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. The potential milestone payments that the Company is eligible to receive were excluded from the transaction price, as all milestone amounts were fully constrained based on the probability of achievement.
