(the &#x201C;Company&#x201D;) was incorporated on March&#xA0;26, 2004 under the laws of the State of Delaware. The Company is a biopharmaceutical company focused on developing and commercializing innovative therapies for the treatment of prostate cancer and other hormonally-driven diseases. The Company has focused substantially all of its research and development efforts on the development of galeterone, an oral small molecule, including clinical trials of galeterone for the treatment of patients with metastatic castration-resistant prostate cancer (&#x201C;mCRPC&#x201D;). The Company also has a drug discovery program, known as ARDA (androgen receptor degradation agents), under which it identified novel compounds for patients with androgen receptor signaling diseases, including prostate cancer.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> In July&#xA0;2016, the Company announced its plan to discontinue <font style="WHITE-SPACE: nowrap">ARMOR3-SV,</font> its pivotal Phase 3 clinical trial comparing galeterone to Xtandi<sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top">&#xAE;</sup> (enzalutamide) in <font style="WHITE-SPACE: nowrap">treatment-na&#xEF;ve</font> mCRPC patients whose prostate tumors expressed the <font style="WHITE-SPACE: nowrap">AR-V7</font> splice variant, following the recommendation made by the trial&#x2019;s independent data monitoring committee (&#x201C;DMC&#x201D;). The Company conducted a review of unblinded data from the <font style="WHITE-SPACE: nowrap">ARMOR3-SV</font> clinical trial to evaluate potential paths forward for galeterone and its ARDA program. Based on data reviewed, there is a substantial likelihood that the Company will not pursue the development of galeterone in <font style="WHITE-SPACE: nowrap">AR-V7</font> positive mCRPC patients in the future. All patients enrolled in the <font style="WHITE-SPACE: nowrap">ARMOR3-SV</font> clinical trial have been discontinued. Following the announcement regarding the discontinuation of the <font style="WHITE-SPACE: nowrap">ARMOR3-SV</font> trial, the Company reduced its workforce in the third quarter of 2016 by approximately 60%.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> In addition, in August 2016, the Company determined to discontinue enrollment in its Phase 2 ARMOR2 expansion clinical trial of galeterone in mCRPC patients with acquired resistance to Xtandi and not to proceed with its planned study of galeterone in mCRPC patients who rapidly progress on either enzalutamide or Zytiga <sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top">&#xAE;</sup> (abiraterone acetate).

The objective of this review, which was conducted in parallel with the review of development options for galeterone and the ARDA program, was to maximize shareholder value.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> On December&#xA0;21, 2016, the Company entered into a Share Purchase Agreement (the &#x201C;Share Purchase Agreement&#x201D;) with Otic Pharma, Ltd., a private limited company organized under the laws of the State of Israel (&#x201C;Otic&#x201D;) and the shareholders of Otic (the &#x201C;Selling Shareholders&#x201D;) pursuant to which, among other things, each Selling Shareholder agreed to sell to the Company, and the Company agreed to purchase from each Selling Shareholder, all of the ordinary and preferred shares of Otic (the &#x201C;Otic Shares&#x201D;) owned by such Selling Shareholder (the &#x201C;Otic Transaction&#x201D;). See &#x201C;Note 9. Share Purchase Agreement&#x201D; for further information regarding the Otic Transaction. The Company amended and restated the Share Purchase Agreement on March&#xA0;2, 2017 to update the allocation of shares of the Company&#x2019;s common stock among the Selling Shareholders and to extend to May&#xA0;31, 2017, the date after which the Company or Otic may terminate the Share Purchase Agreement.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> The Company is subject to risks common to companies in the biotechnology industry including, but not limited to, new technological innovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations and the need to obtain additional financing. Galeterone and any product candidates that the Company may seek to develop in the future under the ARDA program or otherwise, will require significant additional research and development efforts, including extensive preclinical and clinical testing, formulation development and manufacturing, and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel infrastructure, and extensive compliance capabilities.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> There can be no assurance that the Company&#x2019;s research and development activities will be successfully completed, that adequate protection for the Company&#x2019;s intellectual property will be obtained or maintained, that any products developed will obtain necessary regulatory approval or that any approved products will be commercially viable. Even if the Company&#x2019;s drug development efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from product sales. The Company operates in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies. In addition, the Company is dependent upon the services of its employees, consultants and contracted service providers.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"> The Company&#x2019;s common stock is currently listed for quotation on the NASDAQ Global Market. On March&#xA0;8, 2017, the Company received a deficiency letter from the Listing Qualifications Department of the NASDAQ Stock Market notifying the Company that, for the last 30 consecutive business days prior to the date of the letter, the bid price for its common stock had closed below the minimum $1.00 per share requirement for continued inclusion on the NASDAQ Global Market. The Company has been provided an initial period of 180 calendar days, or until September&#xA0;4, 2017, to regain compliance with the listing requirements. If, at any time before September&#xA0;4, 2017, the bid price for the Company&#x2019;s common stock closes at $1.00 or more for a minimum of 10 consecutive business days it may be eligible to regain compliance with the minimum bid requirement. Under certain circumstances, NASDAQ could require that the minimum bid price exceed $1.00 for more than ten consecutive days before determining that the Company complies with NASDAQ&#x2019;s continued listing standards. The Company is seeking approval of a reverse stock split at its upcoming Special Meeting of Stockholders to be held on May&#xA0;9, 2017 in connection with the Otic Transaction. The Company expects that the reverse stock split, if approved, would help it regain compliance with the listing standards.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> If the Company&#x2019;s common stock is delisted by NASDAQ, the common stock may be eligible to trade on the OTC Bulletin Board or another <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">over-the-counter</font></font> market. Any such alternative would likely result in it being more difficult for the Company to raise additional capital through the public or private sale of equity securities and for investors to dispose of, or obtain accurate quotations as to the market value of, the common stock and could result in a decrease in the trading price of the Company&#x2019;s common stock. In addition, there can be no assurance that the common stock would be eligible for trading on any such alternative exchange or markets.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> The Company&#x2019;s financial statements have been prepared on the basis of continuity of operations, realization of assets and satisfaction of liabilities in the ordinary course of business. The Company has incurred losses and negative cash flows from operations since inception. As of March&#xA0;31, 2017, the Company had an accumulated deficit of $173,263 and had cash and cash equivalents of $24,400. In light of the discontinuation of the <font style="WHITE-SPACE: nowrap">ARMOR3-SV</font> trial and the reduction in workforce that occurred in the third quarter of 2016 and assuming no new clinical efforts for galeterone or any other product candidate, and that the Company does not successfully consummate the Otic Transaction, the Company expects its cash and cash equivalents as of March&#xA0;31, 2017 to be sufficient to fund operations through at least the first half of 2018. While the Company has entered into the Share Purchase Agreement, its operating plan may change or the consummation of the Otic Transaction may be delayed or may not occur at all. If the Otic Transaction is not consummated, the Company will need to continue its review of strategic alternatives including evaluating potential paths forward for galeterone and its ARDA program. If the Otic Transaction is consummated or if the Company determines to pursue an alternate strategy, its future business, prospects, financial position and operating results could be significantly different than those in historical periods or projected by management.&#xA0;If the Company determines to further develop galeterone, proceed with its ARDA program, or both, the Company will need to obtain substantial additional funding. Because of the significant uncertainty regarding its future plans, the Company is not able to accurately predict the impact of a potential change on its business strategy and future funding requirements. If its cash and cash equivalents are not sufficient to fund its approved strategy and the Company is unable to raise capital when needed or on acceptable terms, the Company may be forced to delay, reduce, terminate or eliminate its product development programs and commercialization efforts.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> The balance sheet at December&#xA0;31, 2016 was derived from audited financial statements, but does not include all disclosures required by U.S. generally accepted accounting principles (&#x201C;GAAP&#x201D;).

ASU <font style="WHITE-SPACE: nowrap">2016-09</font> identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. Accordingly, the Company elected to account for forfeitures as they occur rather than apply a forfeiture rate to stock-based compensation. The impact of the election to account for forfeitures as they occur was not material. Additionally, upon adoption on January&#xA0;1, 2017, the Company&#x2019;s gross deferred tax assets and corresponding valuation allowance each increased by $1,400 related to tax deductions from the exercise of stock options that previously would have been credited to additional <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">paid-in-capital</font></font> when realized.</p> </div> TKAI 306000 <div> <p style="margin-top:6pt;

Immediately following the closing of the Otic Transaction, the Selling Shareholders are expected to own approximately 60% of the Company&#x2019;s outstanding common stock (62% if all of Otic&#x2019;s outstanding options and warrants are exercised prior to closing). Consummation of the Otic Transaction is subject to certain closing conditions, including, among other things, approval by the Company&#x2019;s stockholders at its upcoming Special Meeting of Stockholders to be held on May&#xA0;9, 2017. The Share Purchase Agreement contains certain termination rights for both the Company and Otic, and further provides that, upon termination of the Share Purchase Agreement under specified circumstances, the Company may be required to pay Otic a termination fee of $1,000, or Otic may be required to pay the Company a termination fee of $1,500. Upon the delivery of a fairness opinion of the Otic Transaction, the Company owes its strategic advisor $500. An additional $500 is due to its strategic advisor upon consummation of the transaction with Otic. The Company has expensed $500 during the three months ended March&#xA0;31, 2017 related to the delivery of the fairness opinion. The Company determined the $500 due upon delivery of the fairness opinion should have been accrued as of December&#xA0;31, 2016. The impact of this error was not material to the financial statements for the year ended December&#xA0;31, 2016. The subsequent correction was made in the financial statements for the three months ended March&#xA0;31 2017 and was not material. There can be no assurances that the Otic Transaction will be consummated. The Company amended and restated the Share Purchase Agreement on March&#xA0;2, 2017 to update the allocation of shares of the Company&#x2019;s common stock among the Selling Shareholders, to update the manner in which Otic options and warrants are converted and to extend to May&#xA0;31, 2017, the date after which the Company or Otic may terminate the Share Purchase Agreement.</p> <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"> In addition, the Company has entered into a commitment letter with Otic and certain purchasers set forth therein under which the purchasers have agreed to invest up to $7,000 of new capital in Otic and/or Tokai prior to or upon the closing of the Otic Transaction.
