Subsequent Events [Abstract] |
Subsequent Events | Subsequent EventsOn January 8, 2023, we entered into a new strategic collaboration with Voyager, under which we agreed to pay Voyager $175 million upfront, including a $39 million equity investment, to acquire the worldwide rights to Voyager’s GBA1 gene therapy program for Parkinson’s disease and other GBA1-mediated diseases and three gene therapy programs directed to rare central nervous system targets, each enabled by Voyager’s next-generation TRACER TM capsids. The effectiveness of the collaboration agreement and the closing of the sale and issuance of Voyager common stock are expected to be completed prior to the end of the first quarter of 2023 and are subject to certain conditions including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other customary closing conditions.
