Research and Development ExpensesAll research and development costs are expensed as incurred. Research and development costs consist primarily of salaries, employee benefits, costs associated with preclinical studies and clinical trials (including amounts paid to clinical research organizations and other professional services). Payments made prior to the receipt of goods or services to be used for research and development expense are capitalized until the goods or services are received.The Company records accruals for estimated research and development costs, comprising payments for work performed by third party contractors, laboratories, participating clinical trial sites, and others. Some of these contractors bill monthly based on actual services performed. Other contractors bill periodically based upon achieving certain contractual milestones. For the contractors that bill periodically, the Company accrues the expenses as goods or services are used or rendered. Clinical trial site costs related to patient enrollment are accrued as patients enter and progress through the trial. Upfront costs, such as costs associated with setting up clinical trial sites for participation in the trials, are expensed immediately once incurred as research and development expenses.Patent CostsLegal costs in connection with approved patents and patent applications are expensed as incurred, as recoverability of such expenditures is uncertain.

The grant date fair value of the stock-based awards, which have graded vesting, is recognized using the straight-line method over the requisite service period of each stock-based award, which is generally the vesting period of the respective stock-based awards. The Company recognizes forfeitures as they occur. Income TaxesIncome taxes are accounted for under the asset and liability method.
