License Agreements [Abstract] | |
License Agreements | 7. License Agreements In December 2016, as further amended in February 2017 and amended and restated in July 2018, the Company entered into a license agreement (the “NYU Agreement”) with New York University, pursuant to which the Company obtained a worldwide, royalty-bearing, exclusive license under certain patents and know-how of New York University to research, develop and commercialize products covered by such licensed patents. The Company is required to pay New York University an annual non-refundable license fee, which is creditable against future milestone and royalty payments. The Company is required to pay amounts up to approximately $6.7 million in the aggregate upon achievement of certain clinical and commercial milestones and pay a low single digit royalty on future net sales of any product covered by a licensed product and a lower-single digit royalty on future net sales of any product not covered by a licensed product. The NYU Agreement expires on the date of expiration of all royalty obligations. Any potential future milestone or royalty payment amounts have not been accrued at December 31, 2021 and 2020 due to the uncertainty related to the successful achievement of these milestones. |
