Revenue from Contract with Customer [Abstract]
UCB Option and License Agreement	UCB Option and License Agreement In December 2022, the Company entered into an Option and License Agreement (“the Collaboration Agreement”) with UCB Biopharma SRL (“UCB”) for the discovery of small molecule therapeutics as potential treatments of KCNT1-related epilepsies. Under the terms of the Collaboration Agreement, the Company has agreed to perform general biology-related research services as part of a mutually agreed upon research plan in exchange for a $5.0 million upfront payment. In addition, the Company provided UCB an exclusive option to in-license global development and commercialization rights to any resulting KCNT1 small molecule development candidate identified as part of the research plan. If UCB exercises its option to in-license global development and commercialization rights, the Collaboration Agreement stipulates that UCB will assume research, development, manufacturing and commercialization responsibilities and costs. Under the terms of the Collaboration Agreement, the Company will be eligible to receive an option fee and future success-based development and commercialization milestone payments, totaling up to $98.5 million, in addition to tiered royalties on net sales of any resulting products from the Collaboration Agreement. The Company concluded that UCB is a customer, and as such, the arrangement falls within the scope of Topic 606. At the commencement of the Collaboration Agreement, the Company identified one performance obligation, which was to perform the research services for UCB. The Company determined the transaction price to be $5.0 million, comprised of the upfront payment it received. The option provided to UCB was determined not to be a material right. The Company recognizes revenue for its research services performance obligation over time using an input method over the duration of the research services. During the three and six months ended June 30, 2023, the Company recognized $0.8 million and $1.5 million, respectively, in collaboration revenue related to the Collaboration Agreement in the condensed consolidated statement of operations. As of June 30, 2023, $3.5 million was included in deferred revenue in the condensed consolidated balance sheet, of which $2.0 million was classified as current.
