License Agreements

Genentech

In June 2016, the Company entered into an Exclusive License Agreement with Genentech, Inc. (“Genentech”). This agreement gives the Company access to Genentech’s LRRK2 inhibitor small molecule program for Parkinson's disease. Under the agreement, Genentech granted the Company (i) an exclusive, worldwide, sublicensable license under Genentech’s rights to certain patents and patent applications directed to small molecule compounds which bind to and inhibit LRRK2 and (ii) a non-exclusive, worldwide, sublicensable license to certain related know-how, in each case, to develop and commercialize certain compounds and licensed products incorporating any such compound.

The Company may owe Genentech milestone payments upon the achievement of certain development, regulatory, and commercial milestones, up to a maximum of $315.0 million in the aggregate. These milestones include up to $37.5 million in clinical milestone payments, $102.5 million in regulatory milestone payments and $175.0 million in commercial milestone payments. In addition, the Company may owe royalties on net sales of licensed products ranging from low to high single-digit percentages. In the year ended December 31, 2022, the Company paid Genentech a $7.5 million clinical milestone payment triggered upon the commencement of dosing in the global Phase 2b LUMA study to evaluate the efficacy and safety of BIIB122/DNL151 by the Company's collaboration partner Biogen, and a $5.0 million clinical milestone payment triggered upon the commencement of dosing in the global Phase 3 LIGHTHOUSE study to evaluate the efficacy and safety profile of BIIB122/DNL151 by Biogen.

Under the terms of the Biogen collaboration agreement, Biogen is responsible for 50% of any payment obligation to Genentech after October 4, 2020, including these clinical milestones, and accordingly $6.3 million of research and development expense under this agreement was recognized in the year ended December 31, 2022 associated with these milestones. No expenses were recognized under the Genentech License Agreement in the years ended December 31, 2021 or 2020.

To date, the Company has made payments to Genentech of $25.0 million in the aggregate, including an upfront fee, a technology transfer fee and three clinical milestone payments, with $18.8 million of this recorded as research and development expense as incurred, net of cost sharing reimbursements from Biogen.
