| Interim Financial Information | 1. Interim Financial Information The Company We were incorporated in the state of Delaware in September 2000. We are a development stage biopharmaceutical company focused on acquiring and developing novel, small molecule therapeutics for the treatment of serious diseases with unmet medical needs with a specific focus on the U.S. market. We are currently focusing our development activities on MN-166, an ibudilast-based drug candidate for the treatment of neurological disorders, and obtaining additional funding to advance clinical trial development of MN-221, a novel, highly selective ß2 -adrenergic receptor agonist being developed for the treatment of acute exacerbations of asthma and chronic obstructive pulmonary disease, or COPD. Basis of Presentation We have prepared the accompanying unaudited consolidated financial statements in accordance with accounting principles generally accepted in the U.S. for interim financial information. Accordingly, they do not include all of the information and disclosures required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments of a normal recurring nature necessary for the fair presentation of our financial position, results of operations and cash flow for the interim periods presented have been included. Operating results for the three months ended March 31, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or for any other period. For further information, see the financial statements and disclosures thereto for the year ended December 31, 2012 in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on March 28, 2013. Principles of Consolidation The consolidated financial statements include the accounts of MediciNova, Inc. and its wholly-owned subsidiaries. MediciNova, Inc. and its subsidiaries are collectively referred to herein as “we,” “our” or “us.” On December 13, 2006, MediciNova (Europe) Limited, a wholly-owned subsidiary of MediciNova, Inc., was incorporated under the laws of England and Wales and established for the purpose of facilitating the clinical development of the Company’s product candidates for the European marketplace. MediciNova (Europe) Limited’s functional currency is the U.S. dollar, the reporting currency of its parent. On January 4, 2007, MediciNova Japan, Inc., a wholly-owned subsidiary of MediciNova, Inc., was incorporated under the laws of Japan and established to strengthen business development and investor and public relations activities in Japan and other Asian countries. MediciNova Japan, Inc.’s functional currency is the Japanese yen. On August 17, 2009, Absolute Merger, Inc., a wholly-owned subsidiary of MediciNova, Inc. was incorporated under the General Corporation Law of the State of Delaware for the purpose of facilitating the acquisition with Avigen. All intercompany transactions and investments in our subsidiaries have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates.
Revenue Recognition and Deferred Revenue In October 2011, we entered into an agreement with Kissei Pharmaceutical Co., Ltd., or Kissei, to perform research and development services relating to MN-221 in exchange for a non-refundable upfront payment of $2.5 million. Under the terms of the agreement, we are responsible for all costs to be incurred in the performance of these services. Certain of these research and development services were completed in 2012 and the remaining services are expected to be delivered and completed after 2013. We are recognizing the $2.5 million payment as revenue as the research and development services are performed. The amount received from Kissei, net of the amount recorded as revenue to date, is included on the balance sheet as deferred revenue and will be recognized as revenue as we perform the remaining services. Revenue recorded in the three months ended March 31, 2013 and 2012 was approximately $3,000 and $191,000, respectively. Concentrations and Credit Risk We maintain cash balances at various financial institutions and such balances commonly exceed the $250,000 insured amount by the Federal Deposit Insurance Corporation. We also maintain money market funds at various financial institutions which are not federally insured, although they are invested primarily in U.S. government securities. We have not experienced any losses in such accounts and management believes that we do not have significant credit risk with respect to such cash and cash equivalents. |

| Joint Venture | 2. Joint Venture We entered into an agreement to form a joint venture company with Zhejiang Medicine Co., Ltd. and Beijing Make-Friend Medicine Technology Co., Ltd. effective September 27, 2011. The joint venture agreement provides for the joint venture company, Zhejiang Sunmy Bio-Medical Co., Ltd. (“Zhejiang Sunmy”), to develop and commercialize MN-221 in China. A sublicense, which will require the consent of the licensor, will be required for us to license MN-221 to Zhejiang Sunmy. In accordance with the joint venture agreement, in March 2012 we paid $680,000 for a 30% interest in Zhejiang Sunmy. The other parties to the joint venture agreement provided funding for their combined 70% interest and are responsible for future funding of Zhejiang Sunmy’s activities. We have not entered into the sublicense of MN-221 with Zhejiang Sunmy as of the date of this report. Zhejiang Sunmy is a variable interest entity for which we are not the primary beneficiary as we do not have a majority of the board seats and we will not have power to direct or significantly influence the actions of the entity. We therefore account for the activities of Zhejiang Sunmy under the equity method whereby we absorb any loss or income generated by Zhejiang Sunmy according to our percentage ownership. At March 31, 2013 we reflect a long-term asset on our consolidated balance sheet which represents our investment in Zhejiang Sunmy, net of our portion of any generated loss or income. |

| Fair Value Measurements | 3. Fair Value Measurements As defined in the authoritative guidance for fair value measurements and disclosures under ASC 820, fair value is based on the price that would be received to sell an asset or would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability and consistency of fair value measurements, ASC 820 prescribes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels which are described below:
The following table presents our financial instruments measured at fair value on a recurring basis classified by the fair value measurements and disclosures valuation hierarchy (in thousands):
At March 31, 2013, cash equivalents (instruments with maturities of three months or less at the date of purchase) were primarily invested in money market accounts, the fair value of which is based on Level 1 criteria in which their carrying amount is a reasonable estimate of their fair value based on daily quoted market prices. At March 31, 2013 and December 31, 2012 we did not hold financial instruments measured at fair value on a non-recurring basis. |

| Net Loss Per Share | 4. Net Loss Per Share Net loss per common share is presented as basic and diluted net loss per common share. Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period using the treasury-stock method. For purposes of this calculation, convertible preferred stock, stock options and warrants are considered to be common stock equivalents and are only included in the calculation of diluted net loss per common share when their effect is dilutive. Potentially dilutive outstanding securities excluded from diluted net loss per common share because of their anti-dilutive effect:

| Stock-Based Compensation | 6. Stock-Based Compensation For the three months ended March 31, 2013 and 2012, stock-based compensation expense related to stock options and the employee stock purchase plan was approximately $158,000 and $927,000, respectively, and was recorded as a component of general and administrative expense (approximately $93,000 and $646,000, respectively) and research and development expense (approximately $65,000 and $281,000, respectively). During the three months ended March 31, 2013, there were 41,377 stock options exercised from which proceeds of approximately $102,000 were received. There were no options exercised during the three months ended March 31, 2012. As of March 31, 2013, there was $0.8 million of unamortized compensation expense related to unvested stock option awards which is expected to be recognized over a remaining weighted-average vesting period of 0.79 years. No options were granted during the three months ended March 31, 2013 and 2012. As share-based compensation expense recognized in the accompanying consolidated statements of operations and comprehensive loss included expense related to stock option awards ultimately expected to vest, such expense should be reduced for estimated forfeitures. The authoritative guidance for compensation expense requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. As we have a small number of employees, we did not estimate any forfeitures during 2012, or during the three months ended March 31, 2013. We will adjust our stock-based compensation expense when any forfeitures occur. The MediciNova, Inc. 2007 Employee Stock Purchase Plan, or ESPP, permits full-time employees to purchase our common stock through payroll deductions (not to exceed 15% of each employee’s compensation) at the lower of 85% of fair market value at the beginning of the offering period or the end of each six-month offering period. For the three months ended March 31, 2013 and 2012, the number of shares of common stock issued under the ESPP were 16,067 and 15,550 respectively. Shares of common stock available for future issuance at March 31, 2013 and 2012 were 248,511 and 269,442, respectively. The Company uses the Black-Scholes option valuation model for determining the estimated fair value and the stock-based compensation for stock-based awards to employees. The following table provides the assumptions used in the Black-Scholes option-pricing model for the three months ended March 31, 2013 and 2012.

| Income Taxes | 7. Income Taxes In accordance with the authoritative guidance for income taxes under ASC 740, a deferred tax asset or liability is determined based on the difference between the financial statements and the tax basis of assets and liabilities as measured by the enacted tax rates, which will be in effect when these differences reverse. We provide a valuation allowance against net deferred assets unless, based upon the available evidence, it is more likely than not that the deferred tax assets will be realized. The Company recognizes the impact of a tax position in the financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense.
We are subject to taxation in the U.S., California and foreign jurisdictions, of which currently no years are under examination. Our tax years for 2000 and forward are subject to examination by the U.S. and state tax authorities due to the carry-forward of unutilized net operating losses and research and development credits.

| Stockholders' Equity | 9. Stockholders’ Equity Stock Options We grant stock options to our employees, officers, directors and consultants under the MediciNova, Inc. Amended and Restated 2004 Stock Incentive Plan. A summary of the changes in stock options outstanding during the three months ended March 31, 2013 is as follows:
The aggregate intrinsic value of stock options outstanding and options exercisable at March 31, 2013 was approximately $276,000 and $217,000, respectively. The weighted average contractual life of options outstanding at March 31, 2013 was 6.9 years and the weighted average contractual life of exercisable options at March 31, 2013 was 5.9 years. Kissei Stock Purchase In October 2011, pursuant to a stock purchase agreement by and between us and Kissei Pharmaceutical Co. Ltd, or Kissei, Kissei purchased for $7.5 million (i) an aggregate of 800,000 shares of our common stock, par value $0.001 per share, at a price of $2.50 per share, which approximated the fair value of our common stock at the time of the transaction, and (ii) 220,000 shares of our Series B Convertible Preferred Stock, or Series B Preferred, par value $0.01 per share, at a price of $25.00 per share, which approximated the fair value of our preferred stock on an as converted basis at the time of the transaction. The purchase agreement contains customary representations, warranties and covenants and a standstill agreement from Kissei that terminates if Kissei beneficially owns less than three percent of our outstanding voting stock. Each share of the Series B Preferred is convertible into 10 shares of common stock. The Series B Preferred ranks pari passu (on an as-if-converted-to-common-stock basis) with the common stock in liquidation and dividend rights. The holders of the Series B Preferred do not have voting rights, and the consent of a majority of the outstanding Series B Preferred is required for certain actions of the Company. Common Stock Purchase Agreement On August 20, 2012, we entered into a common stock purchase agreement with Aspire Capital Fund LLC, or Aspire, pursuant to which the Company may sell to Aspire, and Aspire would be obligated to purchase, up to an aggregate of $20 million of our common stock over the two year term of the agreement, including $1 million in common stock purchased by Aspire in connection with execution of the agreement. Periodic sales of our common stock to Aspire are subject to certain limitations and the per share sales price is based on closing stock prices at or near each transaction date. No more than 3,231,096 shares of our common stock can be issued under this agreement, including the 363,636 shares issued to Aspire in consideration of entering into the agreement. Our net proceeds will depend on the frequency and number of shares of our common stock sold to Aspire and the per share purchase price of each transaction. We may, on any business day over term of the agreement, direct Aspire to purchase up to 50,000 shares, to a maximum of $500,000 per business day. The purchase price shall be the lower of the lowest sale price of the Company’s common stock on the date of the sale, or the average of the three lowest closing stock prices during the 12 consecutive business days ending on the business day immediately preceding the purchase date. In addition, MediciNova may on any business day over the term of the Agreement, direct Aspire to make a volume-weighted average purchase (“VWAP”) of stock not to exceed 15% (which limitation may be increased up to 30% by the mutual agreement of the parties) of the aggregate shares of our stock traded on the next business day, the purchase price of which shall be the lower of the closing price on the date of the sale, or 95% of the next business day’s Nasdaq volume weighted average price, subject to a minimum market price threshold established by us and certain other exceptions. We initially issued 363,636 shares of our common stock to Aspire as consideration for entering into the agreement. As of March 31, 2013, the Company had completed sales to Aspire totaling 1,656,060 shares of common stock at prices ranging from $1.60 to $2.07 per share, generating gross proceeds of $3.0 million. The agreement provides Aspire certain termination rights, including rights under an event of default as defined therein, under which the Company may not require and Aspire would not be obligated to purchase any shares of our common stock. The Company and Aspire may also not effect any sales under the agreement on any purchase date where the closing price of our common stock is less than $1.00 per share. Issuance of Warrant On August 22, 2012, we issued a warrant in exchange for investor relations services to purchase up to 130,000 of our common shares at a price of $1.88 per share, the closing price of our common stock on that date. The warrant contains provisions whereby the warrant becomes exercisable for specified shares of our common stock as a result of our stock achieving certain share price targets within a 15 month period beginning on August 22, 2012. The warrant expires in five years. The warrant is valued at its fair value of approximately $100,000 on August 22, 2012, is classified as equity and as a prepaid expense, and is being amortized over the one year period beginning August 22, 2012. |

Subsequent Events At-The-Market Equity Distribution Agreement On April 17, 2013, we entered into an at-the-market equity distribution agreement with Macquarie Capital (USA) Inc. (“MCUSA”) pursuant to which the Company may from time to time sell through MCUSA, acting as our sales agent, shares of our common stock up to an aggregate offering price of $6 million. Unless mutually agreed otherwise, no sale of an amount of shares of our common stock may be greater than the lower of $50,000 and 10% of the lower of the 5-day or 3-month average daily traded value of our common stock as reported by Bloomberg as of the date of the applicable issuance notice, and the price per share may not be less than the greater of $1.19 or the last available closing price of a share of common stock on The Nasdaq Global Market. MCUSA will use its commercially reasonable efforts consistent with its customary trading and sales practices and applicable laws, rules and regulations to sell shares of our common stock and may sell such shares by any method permitted by law deemed to be “at the market”. We will pay MCUSA an aggregate commission rate of 8.0% of the gross proceeds of any common stock sold through MCUSA under the agreement. MCUSA is under no obligation to purchase shares pursuant to this agreement and there are no assurances that MCUSA will be successful in selling shares. Our net proceeds will depend on the number of shares of our common stock sold to MCUSA and the per share purchase price of each transaction. The agreement with MCUSA provides both MCUSA and the Company the right to terminate the agreement in its sole discretion upon giving five business days written notice. Between April 17, 2013 and the date of this report, we have generated net proceeds of $2.8 million under this agreement on sales of 895,000 shares of our common stock. Common Stock Purchase Agreement Between August 21, 2012 and the date of this report, we have generated proceeds of $4.3 million under the common stock purchase agreement with Aspire, including proceeds of $1.4 million on the sale of 497,612 shares of our common stock subsequent to March 31, 2013. Legal Proceedings With regard to the lawsuit filed on July 8, 2011 by a former employee discussed in Note 8. “Commitments and Contingencies”, on April 30, 2013 the arbitrator dismissed this action and awarded monetary sanctions to the Company of approximately $100,000. |

For further information, see the financial statements and disclosures thereto for the year ended December 31, 2012 in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on March 28, 2013. |
| Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of MediciNova, Inc. and its wholly-owned subsidiaries. MediciNova, Inc. and its subsidiaries are collectively referred to herein as “we,” “our” or “us.” On December 13, 2006, MediciNova (Europe) Limited, a wholly-owned subsidiary of MediciNova, Inc., was incorporated under the laws of England and Wales and established for the purpose of facilitating the clinical development of the Company’s product candidates for the European marketplace. MediciNova (Europe) Limited’s functional currency is the U.S. dollar, the reporting currency of its parent. On January 4, 2007, MediciNova Japan, Inc., a wholly-owned subsidiary of MediciNova, Inc., was incorporated under the laws of Japan and established to strengthen business development and investor and public relations activities in Japan and other Asian countries. MediciNova Japan, Inc.’s functional currency is the Japanese yen. On August 17, 2009, Absolute Merger, Inc., a wholly-owned subsidiary of MediciNova, Inc. was incorporated under the General Corporation Law of the State of Delaware for the purpose of facilitating the acquisition with Avigen. All intercompany transactions and investments in our subsidiaries have been eliminated in consolidation. |
| Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates. |
| Revenue Recognition and Deferred Revenue | Revenue Recognition and Deferred Revenue In October 2011, we entered into an agreement with Kissei Pharmaceutical Co., Ltd., or Kissei, to perform research and development services relating to MN-221 in exchange for a non-refundable upfront payment of $2.5 million. Under the terms of the agreement, we are responsible for all costs to be incurred in the performance of these services. Certain of these research and development services were completed in 2012 and the remaining services are expected to be delivered and completed after 2013. We are recognizing the $2.5 million payment as revenue as the research and development services are performed. The amount received from Kissei, net of the amount recorded as revenue to date, is included on the balance sheet as deferred revenue and will be recognized as revenue as we perform the remaining services. Revenue recorded in the three months ended March 31, 2013 and 2012 was approximately $3,000 and $191,000, respectively. |
| Concentrations and Credit Risk | Concentrations and Credit Risk We maintain cash balances at various financial institutions and such balances commonly exceed the $250,000 insured amount by the Federal Deposit Insurance Corporation. We also maintain money market funds at various financial institutions which are not federally insured, although they are invested primarily in U.S. government securities. We have not experienced any losses in such accounts and management believes that we do not have significant credit risk with respect to such cash and cash equivalents. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
