Commitments And Contingencies Disclosure [Abstract] |
Commitments and Contingencies | 11. Commitments and Contingencies The Company contracts to conduct research and development activities with third parties. Certain of these contracts commit the Company to pay future milestone payments up to $15.0 million or to pay royalty fees ranging from 3-6% if any of the research results in regulatory approval or commercial revenue for a product. The scope of the services under the research and development contracts can be modified and the contracts cancelled by the Company upon written notice. In some instances, the contracts may be cancelled by the third party upon written notice. If the Company were to cancel these contracts as of September 30, 2020, the Company would be required to pay certain termination costs and other fees of approximately $2.1 million that would be incurred in future periods. As of September 30, 2020, the Company has non-cancellable purchase commitments for 2020 with certain manufacturing vendors in the amount of approximately $3.1 million. Following regulatory approval by the FDA or EMA of pegcetacoplan for the treatment of PNH, the Company has certain payment and other obligations under the SFJ Agreement, which are discussed above in Note 4.
