A savings certificate entitling the Entity (that is, bearer) to receive interest at an established maturity date, based upon a fixed interest rate. A certificate of deposit may be issued in any denomination. Certificates of deposit are generally issued by commercial banks and, therefore, insured by the FDIC (up to the prescribed limit). Certificates of deposit generally restrict holders from withdrawing funds on demand without the incurrence of penalties. Generally, only certificates of deposit with original maturities of three months or less qualify as cash equivalents. Original maturity means original maturity to the entity holding the investment. As a related 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

| Organization and Description of Business |
Catalyst Pharmaceutical Partners, Inc. (the Company) is a development-stage specialty pharmaceutical company focused on the development and commercialization of novel prescription drugs targeting rare (orphan) neuromuscular and neurological diseases, including Lambert-Eaton Myasthenic Syndrome (LEMS) and infantile spasms. The Company has incurred operating losses in each period from inception through September 30, 2013. The Company has been able to fund its cash needs to date through several public and private offerings of its common stock and warrants, through government grants, and through an investment by a strategic purchaser. See Note 9. Capital Resources On December 3, 2010, the Company filed a Shelf Registration Statement on Form S-3 (the 2010 Shelf Registration Statement) with the SEC to sell up to $30 million of common stock and common stock purchase warrants. This registration statement (file No. 333-170945) was declared effective by the SEC on December 15, 2010. The Company has conducted four registered direct offerings under the 2010 Shelf Registration Statement. See Note 9. The number of shares that the Company could sell in the future and the amount of the gross proceeds that the Company could raise (in the aggregate) under the 2010 Shelf Registration Statement was limited to 20% of the number of shares of outstanding common stock and 33% of the Company’s public float, respectively, pursuant to applicable NASDAQ marketplace and SEC rules. As of September 30, 2013, there is no further availability under the 2010 Shelf Registration Statement. While there can be no assurance, based on currently available information, the Company estimates that it has sufficient working capital to support its operations through the end of 2014. The Company will require additional capital to support the Company’s operations in periods after 2014. The Company may raise required funds through public or private equity offerings, debt financings, corporate collaborations, governmental research grants or other means. The Company may also seek to raise new capital to fund additional product development efforts, even if it has sufficient funds for its planned operations. Any sale by the Company of additional equity or convertible debt securities could result in dilution to the Company’s current stockholders. There can be no assurance that any such required additional funding will be available to the Company at all or available on terms acceptable to the Company. Further, to the extent that the Company raises additional funds through collaborative arrangements, it may be necessary to relinquish some rights to the Company’s drug candidates or grant sublicenses on terms that are not favorable to the Company. If the Company is not able to secure additional funding when needed, the Company may have to delay, reduce the scope of, or eliminate one or more research and development programs, which could have an adverse effect on the Company’s business. |

In the opinion of management, the accompanying unaudited interim financial statements of the Company contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the financial position of the Company as of the dates and for the periods presented. Accordingly, these statements should be read in conjunction with the financial statements and notes thereto for the year ended December 31, 2012 included in the 2012 Annual Report on Form 10-K filed by the Company with the SEC. The results of operations for the three and nine months ended September 30, 2013 are not necessarily indicative of the results to be expected for any future period or for the full 2013 fiscal year.
Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
As of September 30, 2013, there were outstanding stock options to purchase 3,488,906 shares of common stock, of which stock options to purchase 2,805,574 shares of common stock were exercisable as of September 30, 2013. For the three and nine month periods ended September 30, 2013 and 2012, the Company recorded stock-based compensation expense as follows:
Potentially dilutive options to purchase common stock as of September 30, 2013 and 2012 have exercise prices ranging from $0.47 to $6.00 and $0.62 to $6.00, respectively. Potentially dilutive warrants to purchase common stock as of September 30, 2013 and 2012 have exercise prices ranging from $1.04 to $2.08.

| Warrants Liability, at Fair Value |
2011 Warrants The Company allocated approximately $1.3 million of proceeds from its October 2011 registered direct offering to the fair value of common stock purchase warrants issued in connection with the offering that are classified as a liability (the 2011 warrants). The 2011 warrants are classified as a liability because of provisions in such warrants that allow for the net cash settlement of such warrants in the event of certain fundamental transactions (as defined in the warrant agreement). The valuation of the 2011 warrants is determined using the Black-Scholes Model. This model uses inputs such as the underlying price of the shares issued when the warrant is exercised, volatility, risk free interest rate and expected life of the instrument. The Company has determined that the 2011 warrants liability should be classified within Level 3 of the fair value hierarchy by evaluating each input for the Black-Scholes Model against the fair value hierarchy criteria and using the lowest level of input as the basis for the fair value classification. There are six inputs: closing price of the Company’s common stock on the day of evaluation; the exercise price of the warrants; the remaining term of the warrants; the volatility of the Company’s common stock; annual rate of dividends; and the risk free rate of return. Of those inputs, the exercise price of the warrants and the remaining term are readily observable in the warrants agreement. The annual rate of dividends is based on the Company’s historical practice of not granting dividends. The closing price of the Company’s common stock would fall under Level 1 of the fair value hierarchy as it is a quoted price in an active market. The risk free rate of return is a Level 2 input, while the historical volatility is a Level 3 input in accordance with the fair value accounting guidance. Since the lowest level input is a Level 3, the Company determined the warrants liability is most appropriately classified within Level 3 of the fair value hierarchy. This liability is subject to fair value mark-to-market adjustment each reporting period. The calculated value of the 2011 warrants liability was determined using the Black-Scholes Model with the following assumptions:
The following table rolls forward the fair value of the Company’s warrants liability activity for the three and nine month periods ended September 30, 2013 and 2012:
During the three month period ended September 30, 2013, 110,000 of the 2011 warrants were exercised, with proceeds to the company of $143,000. The Company recognizes the change in the fair value of the warrants liability as a non-operating income or loss in the accompanying statements of operations. |

Brookhaven has formally advised the Company that they believe that the amount potentially due from the Company to Brookhaven for reimbursement of patent related expenses is approximately $1.3 million. The Company has advised Brookhaven that it disputes their determination of patent-related expenses due under the license agreement. There can be no assurance as to the outcome of this matter. In any event, no patent-related expenses are due to Brookhaven under the license agreement until the submission by the Company of an NDA for CPP-109. As the Company has not yet filed an NDA for CPP-109, no amounts relating to this matter are accrued in the accompanying September 30, 2013 and December 31, 2012 condensed balance sheets. See Note 12.
Under the license agreement with Northwestern, the Company will be responsible for continued research and development of any resulting product candidates. As of September 30, 2013, the Company has paid $246,590 in connection with the license and has accrued license fees of $51,250 in the accompanying September 30, 2013 condensed balance sheet for expenses, maintenance fees and milestones. In addition, the Company is obligated to pay certain milestone payments in future years relating to clinical development activities with respect to CPP-115, and royalties on any products resulting from the license agreement. The next milestone payment of $150,000 is due on the earlier of successful completion of the first Phase 2 clinical trial of CPP-115 or August 27, 2015.
Initially, the $5,000,000 investment from BioMarin was treated as a loan to the Company. However, on December 10, 2012, the loan automatically converted, at a conversion rate of $0.75 per share, into 6,666,667 shares of the Company’s authorized but unissued common stock. As part of the License Agreement, the Company has taken over a Phase 3 Trial previously being conducted by BioMarin and is obligated to use its diligent efforts to seek to obtain regulatory approval for and to commercialize Firdapse™ in the United States. The Company is obligated to use diligent efforts to complete the double-blind treatment phase of the Phase 3 trial within 24 months of entering into the License Agreement, and BioMarin has the right to terminate the License Agreement if such treatment phase has not been completed in such 24-month period (unless the Company is using diligent effort to pursue the completion of such treatment phase and has spent at least $5 million in connection with the conduct of the Phase 3 Trial during such 24 month period). As of September 30, 2013, the Company had disbursed approximately $3.3 million in connection with expenses related to the Phase 3 trial, and the Company anticipates that the remaining $1.7 million will be expended during 2013. As part of the License Agreement, the Company has agreed: (i) to pay BioMarin certain royalty payments based on net sales in North America; (ii) to pay to a third-party licensor of the rights sublicensed certain royalty payments based on net sales in North America, and (iii) to pay certain milestone payments that BioMarin is obligated to make (approximately $2.6 million of which will be due upon acceptance by the FDA of a filing of an NDA for Firdapse™ for the treatment of LEMS, and approximately $7.2 million of which will be due on the unconditional approval by the FDA of an NDA for Firdapse™ for the treatment of LEMS). The Company has also agreed to share in the cost of certain post-marketing studies that are being conducted by BioMarin if such studies are required as a condition for approval of the product by the FDA. However, no such payments will be due until an NDA has been filed for Firdapse™.

2010 Shelf Registration Statement On December 3, 2010, the Company filed a Shelf Registration Statement on Form S-3 (the 2010 Shelf Registration Statement) with the SEC to sell up to $30 million of common stock and common stock purchase warrants. This registration statement (file No. 333-170945) was declared effective by the SEC on December 15, 2010. The Company has to date conducted the following sales under the 2010 Shelf Registration Statement:
The number of shares that the Company can sell and the amount of the gross proceeds that the Company can raise (in the aggregate) at any one time under its currently outstanding Shelf Registration Statement is limited to 20% of the number of shares of outstanding common stock and 33% of the Company’s public float, respectively, pursuant to applicable NASDAQ marketplace and SEC rules. 2012 Form S-1 Registration Statement On May 24, 2012, the Company sold 6,000,000 shares of its common stock together with common stock purchase warrants to purchase 6,000,000 shares of the Company’s common stock, at a price of $0.80 per share and corresponding warrant. These securities were issued pursuant to a Form S-1 registration statement that became effective on May 23, 2012 (file no. 333-180167). The Company received gross proceeds of approximately $4.8 million from this offering, before underwriting commission and other expenses totaling approximately $795,000. The May 2012 warrants, which expire five years from this offering, before underwriting commission and other expenses totaling approximately $795,000. The May 2012 warrants, which expire five years from their date of issuance and have an exercise price of $1.04 per share, have been accounted for as equity instruments, since they do not contain features (such as net cash settlement or anti-dilution features) that would preclude the Company from accounting for these warrants as equity. Warrant Exercises During the three month period ended September 30, 2013, the Company issued an aggregate of 3,716,250 shares of its authorized but unissued common stock upon the exercise of previously issued common stock purchase warrants, raising gross proceeds of approximately $3.9 million. Nasdaq Listing The Company’s common stock currently trades on the Nasdaq Capital Market. On December 24, 2012, the Company received a staff deficiency letter from The Nasdaq Stock Market (Nasdaq) notifying the Company that it was not in compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on the Nasdaq Capital Market. The Nasdaq Listing Rules (the Rules) require listed securities to maintain a minimum bid price of $1.00 per share and, based on the then closing bid prices for the last 30 consecutive business days, the Company no longer met that requirement. Under the Rules, the Company had a grace period of 180 days, or until June 24, 2013, to regain compliance. On June 25, 2013, the Company received a letter from the Listing Qualifications Staff of the Nasdaq indicating that the Company had been granted an additional 180 days (until December 23, 2013) to regain compliance with the minimum bid price requirement. On August 1, 2013, the Company received notice from Nasdaq confirming that as a result of the Company’s common stock closing with a bid price of at least $1.00 for at least ten consecutive trading days, the Company had regained compliance with the $1.00 minimum bid price requirement for continued listing on The Nasdaq Capital Market. |

| Subsequent Events |
In October 2013, a securities class action lawsuit was filed against the Company and certain of its executive officers and directors seeking unspecified damages in the U.S. District Court for the Southern District of Florida. The complaint purports to state a claim for violation of federal securities laws on behalf of a class of those who purchased the Company’s common stock between October 31, 2012 and October 18, 2013. The lawsuit is at a very early stage and the Company intends to vigorously defend this lawsuit. While there can be no assurance, the Company does not expect this lawsuit to have a material adverse effect on the Company. On November 8, 2013, effective October 1, 2013, the Company terminated its license agreement with Brookhaven. Under the termination agreement, the Company was released from any future obligation to reimburse Brookhaven for Brookhaven’s patent-related expenses. See Note 7. |

| Fair Value Measurements |
Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
