Accounting Policies [Abstract]  
Restricted cash Restricted cash: Restricted cash consists of the 2021 Employee Share Purchase Plan (2021 ESPP) deposits of $0.9 million and $0.3 million as of March 31, 2022 and December 31, 2021, respectively.
Major Customers Major Customers: The Company currently has two main customers for U.S. commercial sales of LUPKYNIS and one customer for sales of voclosporin in the European Union, Japan, as well as the United Kingdom, Russia, Switzerland, Norway, Belarus, Iceland, Liechtenstein and Ukraine. Revenues from two customers accounted for approximately 54% and 45% respectively of the Company's total revenues for the three months ended March 31, 2022. The Company monitors economic conditions, the creditworthiness of customers and government regulations and funding, both domestically and abroad. The Company regularly communicates with its customers regarding the status of receivable balances, including their payment plans and obtains positive confirmation of the validity of the receivables. Global economic conditions and customer specific factors may require the Company to periodically re-evaluate the collectability of its receivables and the Company could potentially incur credit losses.
Accounts receivable, net Accounts receivable, net: Accounts receivable are stated at their net realizable value. As of March 31, 2022 and December 31, 2021, accounts receivable, net are $20.4 million and $15.4 million. We estimate the allowance for doubtful accounts using current expected credit loss model, or CECL model. Under the CECL model, the allowance for doubtful accounts reflects the net amount expected to be collected from the account receivables. We evaluate the collectability of these cash flows based on the asset’s amortized cost, the risk of loss even when that risk is remote, losses over an asset’s contractual life, and other relevant information available to us. Accounts receivable balances are written off against the allowance when it is probable thatthe receivable will not be collected. The allowance for doubtful accounts was $nil as of March 31, 2022 and as of December 31, 2021
Share-based Compensation Share-Based Compensation: The Company follows ASC Topic 718, Compensation - Stock Compensation (ASC 718), which requires the measurement and recognition of compensation expense, based on estimated fair values, for all share-based awards made to employees and directors. The Company records compensation expense based on the fair value on the grant date using the graded accelerated vesting method for all share-based payments related to stock options, performance awards (PAs), restricted stock units (RSUs) and purchases under the Company's 2021 ESPP. For stock options, forfeitures are estimated based on historical experience at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. For RSUs and PAs, forfeitures are accounted for as they occur.
