Asset Purchase Agreement with Blueprint

​

On February 22, 2024, we acquired the US rights to research, develop, manufacture and commercialize GAVRETO (pralsetinib) from Blueprint pursuant to an Asset Purchase Agreement. The acquired assets include, among other things, applicable intellectual property related to pralsetinib in the US, including patents, copyrights and trademarks, as well as clinical regulatory and commercial data and records. Pursuant to the Asset Purchase Agreement, we agreed to pay a purchase price of $15.0 million, of which, $10.0 million was payable upon our first commercial sale of GAVRETO and an additional $5.0 million is payable on the first anniversary of the closing date of the agreement, subject to certain conditions. Blueprint is also eligible to receive up to $97.5 million in future commercial milestone payments and up to $5.0 million in future regulatory milestone payments. The potential regulatory milestones include full regulatory approval of pralsetinib (or related compounds) for the treatment of adult RET-fusion positive thyroid cancer, and maintenance of the current regulatory approval of pralsetinib for the treatment of adult RET-fusion positive thyroid cancer during the period beginning on February 22, 2024 and ending on the third anniversary of the first commercial sale of pralsetinib subject to certain conditions. Subject to the terms and conditions of the Asset Purchase Agreement, Blueprint would be entitled to tiered royalty payments on net sales of products containing pralsetinib (or related compounds) ranging from 10% to 30%, subject to certain reductions and offsets.

​

In accordance with ASC 805 Business Combinations (ASC 805), the transaction was accounted for as an asset acquisition, because substantially all of the fair value of the gross assets acquired is concentrated in a single asset, which is the GAVRETO product rights. The GAVRETO product rights comprised developed technology, customers, trademarks and trade name, and are considered a single asset as they are inextricably linked. ASC 805 provides for a screen test, wherein if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the assets acquired are not considered to be a business.

The following table summarizes the total purchase consideration in connection with the asset acquisition (in thousands):

​

​

The closing purchase price was recorded within acquisition-related liabilities in the condensed balance sheet and was outstanding as of June 30, 2024, of which, $10.0 million was paid in July 2024 following our first commercial sale of GAVRETO at the end of June 2024. The transaction costs have been paid in cash as of June 30, 2024. The contingent considerations relating to future commercial and regulatory milestones were not included in the total purchase price consideration, and will be accounted for when the contingency is resolved and the consideration becomes payable. Royalties will be recognized within cost of sales, as revenue from GAVRETO product sales is recognized.

​

In an asset acquisition, the acquiring entity should recognize the assets acquired at cost to the acquiring entity which includes transaction costs and consideration given, allocated based on a relative fair value of the assets acquired measured at acquisition date. The fair value of the developed technology, customers, trademarks and trade name was

estimated using a multi-period excess earnings income approach that discounts expected cash flows to present value by applying discount rate that represents the estimated rate that market participants would use to value such assets. The relative fair value are based on estimates that required judgement and certain assumptions, categorized as Level 3 in the fair value hierarchy. Since we acquired a single asset, the total purchase consideration was recorded as intangible assets. The related intangible assets is being amortized on a straight-line basis over the estimated useful life of 12 years, and the related amortization is recorded within cost of sales.

​

Simultaneously and in connection with entering into the Asset Purchase Agreement, we also entered into certain supporting agreements, including a customary transition agreement, pursuant to which, during the transition period, Blueprint will transition regulatory and distribution responsibility for GAVRETO to us. We also agreed to purchase certain drug product inventories from Blueprint under a Material Transfer Agreement, and received such inventories amounting to approximately $6.5 million during the six months ended June 30, 2024.

License and Transition Services Agreement with Forma

We have a license and transition services agreement with Forma entered in July 2022, for an exclusive license to develop, manufacture and commercialize olutasidenib, a proprietary inhibitor of mutated IDH1 (mIDH1), for any uses worldwide, including for the treatment of AML and other malignancies. Forma became a wholly owned subsidiary of Novo Nordisk following the closing of its acquisition by Novo Nordisk in October 2022. Pursuant to the terms of the license and transition services agreement, we paid an upfront fee of $2.0 million, with the potential to pay up to $67.5 million of additional payments upon achievement of specified development and regulatory milestones and up to $165.5 million of additional payments upon achievement of certain commercial milestones. In addition, subject to the terms and conditions of the license and transition services agreement, Forma would be entitled to tiered royalty payments on net sales of licensed products at percentages ranging from low-teens to mid-thirties, as well as certain portion of our sublicensing revenue, subject to certain standard reductions and offsets.

The transaction was accounted for as an acquisition of asset under ASC 730, Research and Development. In accordance with the guidance, in a transaction accounted for as an asset acquisition, any acquired IPR&D that does not have alternative future use is charged to expense at the acquisition date. At the acquisition date, the acquired license asset was accounted for as IPR&D, and we anticipated no other economic benefit to be derived from such acquired licensed asset other than the primary indications. As such, we accounted for the upfront fee of $2.0 million as IPR&D and recorded such cost within research and development expense in the statements of operations in 2022.

Under the accounting guidance, we account for contingent payments when a contingency is resolved, and the consideration becomes payable. We account for milestone payment obligations incurred at development stage and prior to a regulatory approval of an indication associated with the acquired licensed asset as research and development expense when the event requiring payment of the milestone occurs. Milestone payment obligations incurred upon and after a regulatory approval of an indication associated with the acquired licensed asset, and at the commercial stage, are recorded as intangible assets when the event requiring payment of the milestones occurs. Prior to the FDA approval of REZLIDHIA in December 2022, a certain regulatory milestone was met which entitled Forma to receive a $2.5 million milestone payment. Because such milestone payment obligation was incurred prior to a regulatory approval of an indication associated with the acquired licensed asset, we recorded such amount as research and development expense in the fourth quarter of 2022. On December 1, 2022, the FDA approved REZLIDHIA capsules for the treatment of adult patients with R/R AML with susceptible IDH1 mutations as detected by an FDA-approved test. Following the FDA approval, we launched REZLIDHIA and made first shipments of the product to our customers in December 2022. With this FDA approval and first commercial sale of the product, Forma was entitled to receive a total of $15.0 million milestone payments. Since such milestone payment obligations were incurred upon and after regulatory approval of the product, we recorded such amount as intangible assets on our condensed balance sheet in the fourth quarter of 2022. No new milestone was met in 2023 and during the six months ended June 30, 2024.

The amount recorded as intangible asset is being amortized on a straight-line basis over the estimated useful life of 14 years, and the related amortization is recorded within cost of sales. Royalties are recognized within cost of sales, as revenue from REZLIDHIA product sales is recognized.
