Basis of Presentation and Summary of Significant Accounting Policies	1. Basis of Presentation and Summary of Significant Accounting Policies
	Description of Business and Basis of Presentation
	Corcept Therapeutics Incorporated was incorporated in the state of Delaware in May 1998, and our headquarters are located in Menlo Park, California. We are a pharmaceutical company engaged in the discovery, development and commercialization of medications for the treatment of severe metabolic, oncologic, and psychiatric disorders that are associated with the activity of the hormone cortisol. In 2012, the United States Food and Drug Administration (FDA) approved Korlym® (mifepristone) 300 mg Tablets as a once-daily oral medication for treatment of hyperglycemia secondary to hypercortisolism in adult patients with endogenous Cushing’s syndrome who have type 2 diabetes mellitus or glucose intolerance and have failed surgery or are not candidates for surgery. In 2014, we began a Phase 1/2 study of Korlym in combination with eribulin for the treatment of triple-negative breast cancer. In addition, we have discovered and patented three families of selective GR antagonists, consisting of more than 300 distinct compounds, with the goal of identifying treatments for a broad range of disorders. We have also completed the clinical portion of a Phase 1 study of CORT125134, one of our next-generation selective GR antagonists, which has shown that the compound is well-tolerated and is functionally active.
	Basis of Presentation
	The accompanying unaudited condensed balance sheet as of March 31, 2015 and the condensed statements of comprehensive loss for the three-month periods ended March 31, 2015 and 2014 and the condensed statements of cash flows for the three-month periods ended March 31, 2015 and 2014 have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three-month period ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2014 included in our Annual Report on Form 10-K. The accompanying balance sheet as of December 31, 2014 has been derived from audited financial statements at that date.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates.
	We evaluate our estimates and assumptions on an ongoing basis, including those related to our reserves for chargebacks and rebates, allowances for patient assistance, excess/obsolete inventories, accruals of clinical and preclinical expenses, and the timing of payments with respect to our long-term capped royalty obligation, which determine its effective interest rate. We base our estimates on relevant experience and on other specific assumptions that we believe are reasonable.
	Fair Value Measurements
	We categorize financial instruments in a fair value hierarchy that prioritizes the information used to develop assumptions for measuring fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 input), then to quoted prices in non-active markets or in active markets for similar assets or liabilities, inputs other than quoted prices that are observable for the asset or liability, and inputs that are not directly observable, but that are corroborated by observable market data for the asset or liability (Level 2 input), then the lowest priority to unobservable inputs, for example, our own data about the assumptions that market participants would use in pricing an asset or liability (Level 3 input). Fair value is a market-based measurement, not an entity-specific measurement, and a fair value measurement should therefore be based on the assumptions that market participants would use in pricing the asset or liability.
	Cash and Cash Equivalents
	We consider all highly liquid investments purchased with maturities of three months or less from the date of purchase to be cash equivalents.  Cash equivalents are carried at fair value as measured using Level 1 inputs, which approximates cost. As of March 31, 2015 and December 31, 2014, all of our funds were held in checking and money market fund accounts maintained at major U.S. financial institutions.
	Trade Receivables
	Trade receivables are recorded net of allowances for patient assistance. We determine our allowance for patient assistance based on existing contractual payment terms, actual payment patterns of our customers and individual customer circumstances.
	Inventory
	We value our inventories at the lower of cost or net realizable value. We determine the cost of inventory using the specific identification method, which approximates a first-in, first-out basis. We write down inventory that has become obsolete or has a cost basis in excess of its expected net realizable value. Any expired inventory is disposed of and the related costs are recognized as cost of sales in the statement of comprehensive loss.
	Inventory amounts that are not expected to be consumed within twelve months following the balance sheet date are classified as strategic inventory, a noncurrent asset.
	We expense the manufacturing costs for product candidates incurred prior to regulatory approval as research and development expense as we incur them. When regulatory approval of a product is obtained, we begin capitalizing manufacturing costs related to the approved product into inventory, provided such product is produced by an FDA approved facility.
	Long-term Obligation
	In August 2012, we entered into a Purchase and Sale Agreement (Financing Agreement) with Biopharma Secured Debt Fund II Sub, S.à r.l (Biopharma), a private limited liability company organized under the laws of Luxembourg. Under the terms of the Financing Agreement, we received $30.0 million from Biopharma, which was recorded as a long-term obligation at issuance. We are obligated to make payments calculated as a percentage of (i) any licensing or other contingent payments arising from Korlym and any other products containing mifepristone or any of our proprietary selective GR antagonists (Covered Products) and (ii) net Covered Product sales earned in the calendar quarter ended June 30, 2013 and thereafter (together, Korlym Receipts), until such time as we have paid Biopharma a total of $45.0 million.
	Interest expense related to the Financing Agreement is calculated based on the internal interest rate to Biopharma that would result from these assumed payment streams.
	The accounting for the Financing Agreement requires us to make certain estimates and assumptions, including the timing of royalty payments due to Biopharma, the expected rate of return to Biopharma, the split between current and long-term portions of the obligation and the accretion of related interest expense. Korlym has only been marketed since April 2012 and the magnitude and timing of Korlym revenue is difficult to predict. Therefore, these estimates and assumptions are subject to significant variability and are likely to change as we gain experience marketing Korlym, which will result in changes in our classification of the current and long-term portions of the amounts payable pursuant to the Financing Agreement, as well as the internal rate of return paid to Biopharma and the accretion of interest expense related to this obligation. The amount of our payment with respect to each quarter will be based on Korlym Receipts recorded in that quarter and may differ from our estimates. While changes in the timing of Korlym revenue may affect the timing of the recognition of interest expense and the split between the current and long-term portions of the obligation at any balance sheet date, the aggregate amount to be repaid to Biopharma is fixed at $45.0 million.
	The amount shown as the current portion of the obligation is an estimate of the total amount under the Financing Agreement that would be paid to Biopharma within 12 months following March 31, 2015.
	See Note 3, Long-Term Obligation, for additional information regarding this agreement.
	Net Product Revenue
	We sell our product directly to patients through Dohmen Life Science Services (Dohmen), a specialty pharmacy. We recognize product revenue from sales of Korlym upon delivery to patients when (i) there is persuasive evidence that an arrangement exists between ourselves and the customer, (ii) collectability is reasonably assured and (iii) the price is fixed or determinable. Prior authorization or confirmation of coverage level by the patient’s private insurance plan or government payor is a prerequisite to the shipment of product to a patient. In order to conclude that the price is fixed or determinable, we must be able to (i) calculate gross product revenue from the sales to our customers and (ii) reasonably estimate net product revenue.
	We donate cash to the National Organization for Rare Disorders (NORD), an independent non-profit organization that provides patients who meet certain eligibility requirements with financial assistance for the treatment of Cushing’s syndrome, which treatment may include Korlym. We do not include in net product revenue payments for Korlym that NORD makes to us on behalf of these patients.
	We estimate our net product revenue by deducting from our gross product revenue (a) estimated government rebates and chargebacks and (b) estimated costs of our patient assistance program.
	Rebates and Chargebacks: We contract with Medicaid and other government programs so that Korlym will be eligible for, purchase by, or qualify for partial or full reimbursement from, such government programs. We estimate the rebates and chargebacks that we are obligated to provide to government programs and deduct these estimated amounts from our gross product revenue at the time the revenue is recognized. We base our estimates of these rebates and chargebacks upon (i) the discount amounts applicable to government-funded programs, and (ii) information obtained from our vendors regarding the percentage of sales by our customers to patients who are covered by entities or programs that are eligible for such rebates and chargebacks.
	Allowances for Patient Assistance Program: We provide financial assistance to eligible patients whose insurance policies require them to pay high deductibles and co-pays. We estimate the cost of assistance to be provided under this program by applying our actual experience regarding such assistance to our estimate of the percentage of our sales in the period that will be provided to patients covered by the program.
	Research and Development
	Research and development expenses consist of direct expenses, such as the cost of clinical trials, pre-clinical studies, manufacturing development, preparations for submissions to the FDA and efforts to prosecute and defend those submissions and the development of second-generation compounds, as well as research and development-related overhead expenses. We also expense as incurred nonrefundable payments to third parties and our cost of acquiring technologies and materials used in research and development that have no alternative future use.
	We base our cost accruals for clinical trials, research and preclinical activities on estimates of work completed under service agreements, milestones achieved, patient enrollment and past experience with similar contracts. Our estimates of work completed and associated cost accruals include our assessments of information from third-party contract research organizations and the overall status of clinical trial and other development and administrative activities.
	Stock-Based Compensation
	We account for stock-based compensation related to option grants to employees and directors under the fair value method, based on the value of the award at the grant date as determined using the Black-Scholes option valuation model. For service-based awards, we recognize expense over the requisite service period.
	We recognize the expense of options granted to non-employees based on the fair-value based measurement of the option grants at the time of vesting. For service-based awards, we recognize expense over the requisite service period.

If either of these companies is unable to manufacture API or Korlym tablets in the quantities and time frame we require, we may not be able to meet our customer demand. In order to mitigate these risks related to the manufacture of our product, we purchased and hold as “strategic inventory” additional quantities of mifepristone API and Korlym tablets that are not expected to be consumed within twelve months following the relevant balance sheet date.

Long-Term Obligation [Abstract]
Long-Term Obligation	3. Long-Term Obligation
	As discussed in Note 1, Basis of Presentation and Summary of Significant Accounting Policies, Long-term Obligation, under the Financing Agreement with Biopharma, we are obligated to make payments calculated as a percentage of our net sales of Korlym, any future mifepristone-based products, our selective GR antagonists (together referred to as Covered Products) and any upfront, milestone or other contingent payments with respect to Covered Products. Biopharma’s right to receive payments will expire once it has received cumulative payments of $45.0 million. Through March 31, 2015, we have paid Biopharma $7.7 million, with an additional payment of $2.1 million made in April 2015.
	Under the terms of the Financing Agreement, our payments are variable, with no fixed minimums. If there are no net sales, upfront, milestone or other contingent payments in a period with respect to Covered Products, then no payment will be due for that period.
	We are obligated to make payments as follows:
		·		20 percent of our net product sales of Covered Products, subject to quarterly payment caps of $3.75 million during 2015. There is no quarterly cap on payments with respect to net product sales in 2016 and later.
		·		20 percent of payments received for upfront, milestone or other contingent fees under co-promotion and out-license agreements for Covered Products (without application of quarterly caps).
		·		The percentage used to calculate our payments to Biopharma would increase to 50 percent and any applicable payment caps would lapse if we (i) fail to provide Biopharma with certain information regarding our promotion and sales of Covered Products, (ii) do not devote a commercially reasonable amount of resources to the promotion and marketing of the Covered Products or (iii) violate the indebtedness covenant by incurring indebtedness greater than the sum of earnings before interest, taxes, depreciation and amortization, including such items as non-cash stock-based compensation, for the four calendar quarters preceding such incurrence and, in each case, fail to cure within the applicable cure period.
		·		Upon the occurrence of a Corcept change of control transaction or the licensing of Korlym to a third-party for promotion and sale in the United States, the entire $45.0 million, less any amounts already paid by us, would become due.
	To secure our obligations in connection with this Financing Agreement, we granted Biopharma a security interest in our rights in patents, trademarks, trade names, domain names, copyrights, know-how and regulatory approvals related to the Covered Products, all books and records relating to the foregoing and all proceeds of the foregoing (together, the Collateral). If we (i) fail to deliver a royalty payment when due and do not remedy that failure within 30 days, (ii) fail to maintain a first-priority perfected security interest in the Collateral in the United States and do not remedy that failure within five business days of receiving notice of such failure or (iii) become subject to an event of bankruptcy, then Biopharma may attempt to recover up to $45.0 million (after deducting any payments we have already made). In addition, pursuant to this agreement, we are not allowed to pay a dividend or other cash distribution, unless we will have cash and cash equivalents in excess of $50.0 million after such payment.
	As discussed in Note 1, Basis of Presentation and Summary of Significant Accounting Policies, Long-term Obligation, we estimate the timing of payments during the term of this agreement for purposes of calculating the expected rate of return to Biopharma, the accretion of related interest expense and the current portion of our obligation. We recorded interest expense of $762,000 and $1.0 million for the three-month periods ended March 31, 2015 and 2014, respectively, and total accreted interest of $10.5 million for the period from August 2012 through March 31, 2015, as calculated based on the internal interest rate to Biopharma that would result from these assumed payment streams. The timing of payment amounts will be based on actual Korlym Receipts recorded in the financial statements over the term of this agreement and may differ from these estimates. While changes in the timing of Korlym revenue may affect the timing of recognition of interest expense and the split between the current and long-term portions of the obligation at any balance sheet date, the aggregate amount to be repaid to Biopharma is fixed at $45.0 million.
	The carrying value of the long-term obligation was $32.8 million as of March 31, 2015 and $33.9 million as of December 31, 2014. The long-term obligation, including accrued interest, is presented on the balance sheet in two components; the Long-term obligation - current portion, which equates to the estimated amount due under the agreement to be paid within twelve months following the balance sheet date, and the remaining amount, which is included in Long-term obligation, net of current portion.
	The following table provides a summary of the payment obligations under the Financing Agreement as of March 31, 2015 and December 31, 2014, utilizing the payment assumptions discussed above.
			March 31,		December 31,
			2015		2014
			(in thousands)
	Total repayment obligation		$	45,000	$	45,000
	Less interest to be accreted in future periods			-4,470		-5,232
	Less payments made			-7,746		-5,881
	Less current portion			-10,658		-9,424
	Long-term obligation, net of current portion		$	22,126	$	24,463
	The estimated fair value of the long-term obligation, as measured using Level 3 inputs, approximates the carrying amounts as presented on the balance sheet as of March 31, 2015 and December 31, 2014. The estimated fair value was calculated using the income method of valuation. The key assumptions required for the calculation were an estimate of the amount and timing of future product revenues and an estimated cost of capital. Management’s estimate of the future product revenues is subject to significant uncertainty due to the fact that Korlym has only been available since 2012 and there is an extended time period associated with the Financing Agreement.
	We capitalized $140,000 of issuance costs related to the Financing Agreement, which are being amortized over the estimated term of the obligation, based on the assumptions discussed above. At March 31, 2015 and December 31, 2014, the unamortized issuance costs were approximately $52,000 and $58,000, respectively, and are included in other assets on our balance sheets.

The transactions generated aggregate net proceeds of approximately $17.1 million, after the deduction of issuance costs. Approximately 3.1 million shares of the securities, which generated aggregate gross proceeds of $5.9 million, issued in these transactions were to venture capital funds, trusts and other entities affiliated with members of our Board of Directors, whom we consider to be our related parties.

The accompanying balance sheet as of December 31, 2014 has been derived from audited financial statements at that date.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates.
	We evaluate our estimates and assumptions on an ongoing basis, including those related to our reserves for chargebacks and rebates, allowances for patient assistance, excess/obsolete inventories, accruals of clinical and preclinical expenses, and the timing of payments with respect to our long-term capped royalty obligation, which determine its effective interest rate. We base our estimates on relevant experience and on other specific assumptions that we believe are reasonable.
Fair Value Measurements	Fair Value Measurements
	We categorize financial instruments in a fair value hierarchy that prioritizes the information used to develop assumptions for measuring fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 input), then to quoted prices in non-active markets or in active markets for similar assets or liabilities, inputs other than quoted prices that are observable for the asset or liability, and inputs that are not directly observable, but that are corroborated by observable market data for the asset or liability (Level 2 input), then the lowest priority to unobservable inputs, for example, our own data about the assumptions that market participants would use in pricing an asset or liability (Level 3 input). Fair value is a market-based measurement, not an entity-specific measurement, and a fair value measurement should therefore be based on the assumptions that market participants would use in pricing the asset or liability.
Cash and Cash Equivalents	Cash and Cash Equivalents
	We consider all highly liquid investments purchased with maturities of three months or less from the date of purchase to be cash equivalents.  Cash equivalents are carried at fair value as measured using Level 1 inputs, which approximates cost. As of March 31, 2015 and December 31, 2014, all of our funds were held in checking and money market fund accounts maintained at major U.S. financial institutions.
Trade Receivables	Trade Receivables
	Trade receivables are recorded net of allowances for patient assistance. We determine our allowance for patient assistance based on existing contractual payment terms, actual payment patterns of our customers and individual customer circumstances.
Inventory	Inventory
	We value our inventories at the lower of cost or net realizable value. We determine the cost of inventory using the specific identification method, which approximates a first-in, first-out basis. We write down inventory that has become obsolete or has a cost basis in excess of its expected net realizable value. Any expired inventory is disposed of and the related costs are recognized as cost of sales in the statement of comprehensive loss.
	Inventory amounts that are not expected to be consumed within twelve months following the balance sheet date are classified as strategic inventory, a noncurrent asset.
	We expense the manufacturing costs for product candidates incurred prior to regulatory approval as research and development expense as we incur them. When regulatory approval of a product is obtained, we begin capitalizing manufacturing costs related to the approved product into inventory, provided such product is produced by an FDA approved facility.
Long-term Obligation	Long-term Obligation
	In August 2012, we entered into a Purchase and Sale Agreement (Financing Agreement) with Biopharma Secured Debt Fund II Sub, S.à r.l (Biopharma), a private limited liability company organized under the laws of Luxembourg. Under the terms of the Financing Agreement, we received $30.0 million from Biopharma, which was recorded as a long-term obligation at issuance. We are obligated to make payments calculated as a percentage of (i) any licensing or other contingent payments arising from Korlym and any other products containing mifepristone or any of our proprietary selective GR antagonists (Covered Products) and (ii) net Covered Product sales earned in the calendar quarter ended June 30, 2013 and thereafter (together, Korlym Receipts), until such time as we have paid Biopharma a total of $45.0 million.
	Interest expense related to the Financing Agreement is calculated based on the internal interest rate to Biopharma that would result from these assumed payment streams.
	The accounting for the Financing Agreement requires us to make certain estimates and assumptions, including the timing of royalty payments due to Biopharma, the expected rate of return to Biopharma, the split between current and long-term portions of the obligation and the accretion of related interest expense. Korlym has only been marketed since April 2012 and the magnitude and timing of Korlym revenue is difficult to predict. Therefore, these estimates and assumptions are subject to significant variability and are likely to change as we gain experience marketing Korlym, which will result in changes in our classification of the current and long-term portions of the amounts payable pursuant to the Financing Agreement, as well as the internal rate of return paid to Biopharma and the accretion of interest expense related to this obligation. The amount of our payment with respect to each quarter will be based on Korlym Receipts recorded in that quarter and may differ from our estimates. While changes in the timing of Korlym revenue may affect the timing of the recognition of interest expense and the split between the current and long-term portions of the obligation at any balance sheet date, the aggregate amount to be repaid to Biopharma is fixed at $45.0 million.
	The amount shown as the current portion of the obligation is an estimate of the total amount under the Financing Agreement that would be paid to Biopharma within 12 months following March 31, 2015.
	See Note 3, Long-Term Obligation, for additional information regarding this agreement.
Net Product Revenue	Net Product Revenue
	We sell our product directly to patients through Dohmen Life Science Services (Dohmen), a specialty pharmacy. We recognize product revenue from sales of Korlym upon delivery to patients when (i) there is persuasive evidence that an arrangement exists between ourselves and the customer, (ii) collectability is reasonably assured and (iii) the price is fixed or determinable. Prior authorization or confirmation of coverage level by the patient’s private insurance plan or government payor is a prerequisite to the shipment of product to a patient. In order to conclude that the price is fixed or determinable, we must be able to (i) calculate gross product revenue from the sales to our customers and (ii) reasonably estimate net product revenue.
	We donate cash to the National Organization for Rare Disorders (NORD), an independent non-profit organization that provides patients who meet certain eligibility requirements with financial assistance for the treatment of Cushing’s syndrome, which treatment may include Korlym. We do not include in net product revenue payments for Korlym that NORD makes to us on behalf of these patients.
	We estimate our net product revenue by deducting from our gross product revenue (a) estimated government rebates and chargebacks and (b) estimated costs of our patient assistance program.
	Rebates and Chargebacks: We contract with Medicaid and other government programs so that Korlym will be eligible for, purchase by, or qualify for partial or full reimbursement from, such government programs. We estimate the rebates and chargebacks that we are obligated to provide to government programs and deduct these estimated amounts from our gross product revenue at the time the revenue is recognized. We base our estimates of these rebates and chargebacks upon (i) the discount amounts applicable to government-funded programs, and (ii) information obtained from our vendors regarding the percentage of sales by our customers to patients who are covered by entities or programs that are eligible for such rebates and chargebacks.
	Allowances for Patient Assistance Program: We provide financial assistance to eligible patients whose insurance policies require them to pay high deductibles and co-pays. We estimate the cost of assistance to be provided under this program by applying our actual experience regarding such assistance to our estimate of the percentage of our sales in the period that will be provided to patients covered by the program.
Research and Development	Research and Development
	Research and development expenses consist of direct expenses, such as the cost of clinical trials, pre-clinical studies, manufacturing development, preparations for submissions to the FDA and efforts to prosecute and defend those submissions and the development of second-generation compounds, as well as research and development-related overhead expenses. We also expense as incurred nonrefundable payments to third parties and our cost of acquiring technologies and materials used in research and development that have no alternative future use.
	We base our cost accruals for clinical trials, research and preclinical activities on estimates of work completed under service agreements, milestones achieved, patient enrollment and past experience with similar contracts. Our estimates of work completed and associated cost accruals include our assessments of information from third-party contract research organizations and the overall status of clinical trial and other development and administrative activities.
Stock-Based Compensation	Stock-Based Compensation
	We account for stock-based compensation related to option grants to employees and directors under the fair value method, based on the value of the award at the grant date as determined using the Black-Scholes option valuation model. For service-based awards, we recognize expense over the requisite service period.
	We recognize the expense of options granted to non-employees based on the fair-value based measurement of the option grants at the time of vesting. For service-based awards, we recognize expense over the requisite service period.
