Item 1.01 Entry into a Material Definitive Agreement.
On July 31, 2024, IDEAYA Biosciences, Inc. (the "Company") announced that it had entered into an Option and License Agreement (the "Agreement"), dated July 30, 2024 (the "Effective Date"), with
Biocytogen Pharmaceuticals (Beijing) Co., Ltd. ("Biocytogen"), pursuant to which Biocytogen granted to the Company an option for an exclusive worldwide license to develop and commercialize products in connection with a potential first-in-class B7H3/PTK7 topo-I-payload bispecific antibody drug conjugate program (the "Option").
Pursuant to the Agreement, the Company will pay Biocytogen an upfront fee and, upon the Company's potential exercise of the Option, an exercise fee totaling up to $6.5 million. The Option is exercisable by the Company within a specified time period after the Company obtains all data and results from certain non-GLP toxicology studies specified in the Agreement, which the Company will conduct at its own cost.
Subject to the Company's exercise of the Option, Biocytogen will be eligible to receive an option exercise fee, development and regulatory milestone payments and commercial milestone payments, as well as low to mid single-digit royalties on net sales. Total potential milestone payments equal an aggregate of $400.0 million, including development and regulatory milestone payments of up to $100.0 million. The Company's royalty obligations continue with respect to each country and each product until the later of (i) the date on which such product is no longer covered by certain intellectual property rights in such country and (ii) the 10
th
anniversary of the first commercial sale of such product in such country.
The Agreement will continue in effect on a product-by-product and country-by-country basis until the expiration of the obligation to make payments under the Agreement with respect to such product in each country, unless earlier terminated by either party pursuant to its terms. Either the Company or Biocytogen may terminate the Agreement for the other party's insolvency or certain uncured material breaches. Biocytogen may terminate the Agreement if the Company or any of its sublicensees or affiliates challenge certain patents of Biocytogen. The Company may terminate the Agreement for any reason upon certain notice to Biocytogen.
The Agreement contains various representations, warranties, covenants, dispute resolution mechanisms, indemnities and other provisions customary for transactions of this nature.
The foregoing is only a summary description of the terms of the Agreement, does not purport to be complete and is qualified in its entirety by reference to the Agreement, which will be filed as an exhibit to the Company's Quarterly Report on Form 10-Q for the fiscal quarter ending September 30, 2024.
On July 31, 2024, the Company issued a press release announcing the Agreement. The full text of the press release issued in connection with the announcement is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
