Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	3. Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include cash and cash equivalents, and accounts payable, approximate their fair values due to their short term maturities. ASC Topic 820 ("ASC 820") Fair Value Measurements applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, ASC 820 does not require any new fair value measurements. The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. The three levels of inputs used are as follows: Level 1 Level 2 Level 3 As of September 30, 2015 and March 31, 2016, the Company had assets and liabilities that fell under the scope of ASC 820. The Company used the Black-Scholes valuation model to determine the fair value of the Company's warrant liability as of September 30, 2015 and March 31, 2016 for the warrants issued in the May 2011 and June 2012 financings (as defined in Note 7). The Black-Scholes valuation model takes into account, as of the valuation date, factors including the current exercise price, the life of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on the stock, and the risk-free interest rate for the term of the warrant. Accordingly, the Company's fair value measurements of its cash and cash equivalents are classified as a Level 1 input and the warrant liability as a Level 3 input. The fair value of the Company's financial assets and liabilities carried at fair value and measured on a recurring basis are as follows: Description Fair Value at Quoted Prices in Significant Other Significant Assets: Cash and cash equivalents and restricted cash $ 33,454 $ 33,454 $ — $ — Subtotal 33,454 33,454 — — Liabilities: Common stock warrant liability (see Note 7) (3 ) — — (3 ) Subtotal (3 ) — — (3 ) Total $ 33,451 $ 33,454 $ — $ (3 ) Description Fair Value at Quoted Prices in Significant Other Significant Assets: Cash and cash equivalents $ 40,845 $ 40,845 $ — $ — Subtotal 40,845 40,845 — — Liabilities: Common stock warrant liability (see Note 7) (5 ) — — (5 ) Subtotal (5 ) — — (5 ) Total $ 40,840 $ 40,845 $ — $ (5 ) The Company recognizes transfers into and out of the levels indicated above on the actual date of the event or change in circumstances that caused the transfer of change. All changes within Level 3 can be found in the following Level 3 reconciliation table below: Balance at September 30, 2015 $ (5 ) Decrease in fair value of common stock warrant liability 2 Balance at March 31, 2016 $ (3 ) The unrealized gains or losses on the derivative liabilities are recorded as an adjustment to fair value of derivative liabilities in the Company's statement of operations. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. At each reporting period, the Company reviews the assets and liabilities that are subject to ASC Topic 815-40. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs or instruments which trade infrequently and therefore have little or no price transparency are classified as Level 3.

Stock-Based Compensation

Stock-Based Compensation [Abstract]
Stock-Based Compensation	4. Stock-Based Compensation In March 2013, the Company's stockholders approved an amendment to and restatement of the Company's 2010 Stock Incentive Plan (as amended and restated the "2010 Plan"). The 2010 Plan replaced the Company's 2004 Stock Incentive Plan and 2005 Non-Employee Directors Stock Option Plan. Stock options are granted at an exercise price equal to the Company's closing stock price on the date of the grant. Stock options vest over a period of up to four years with a contractual life of seven years. The Company estimates the fair value using the Black-Scholes pricing model. The Company uses the following assumptions in its Black Scholes valuation calculations: Risk-free rate Forfeitures Dividends Volatility Expected term In December 2007, the SEC issued SAB No. 110, Share-Based Payment ("SAB No. 110"). SAB No. 110 was effective January 1, 2008 and expresses the views of the Staff of the SEC with respect to extending the use of the simplified method, as discussed in SAB No. 107, in developing an estimate of the expected term of "plain vanilla" share options in accordance with ASC Topic 718. The Company will continue to use the simplified method until it has the historical data necessary to provide a reasonable estimate of expected life in accordance with SAB No. 107, as amended by SAB No. 110. For the expected term, the Company has "plain-vanilla" stock options, and therefore used a simple average of the vesting period and the contractual term for options granted subsequent to January 1, 2006 as permitted by SAB No. 107. The Company expenses ratably over the vesting period the cost of the stock options granted to employees and non-employee directors. The total compensation cost related to options for the three and six months ended March 31, 2016 was $411 and $521, respectively. In comparison, the total compensation cost related to options for the three and six months ended March 31, 2015 was $180 and $341, respectively. The March 31, 2016 expense includes a modification to extend the exercise period for employees affected by the October 2015 and January 2016 RIFs. At March 31, 2016, the total compensation cost related to non-vested options not yet recognized was $399, which will be recognized over the next five years assuming the employees complete their service period for vesting of the options. The following table summarizes the stock option activity during the six months ended March 31, 2016: Number Weighted Weighted Aggregate Outstanding options, September 30, 2015 3,434,597 $ 8.61 5 $ — Granted 1,750,000 $ 0.27 7 2 Forfeited, expired (988,431 ) 15.38 — Outstanding options, March 31, 2016 4,196,166 $ 3.67 4 9 Exercisable options, March 31, 2016 2,199,419 $ 6.51 2 $ 3 The Black-Scholes pricing model assumptions for the options granted during the three and six months ended March 31, 2015 and 2016 are set forth below: Three Months Ended Six Months Ended 2015 2016 2015 2016 Expected life (in years) 3.77-4.75 3.77-4.75 3.77 - 4.75 3.77 - 4.75 Expected volatility 62-82 % 65-67 % 62 - 82 % 65 - 67 % Expected dividend yield 0 % 0 % 0 % 0 % Risk-free interest rate 0.99 - 1.37 % 1.14 - 1.28 % 0.96 - 1.62 % 1.14 - 1.28 % Weighted average grant date fair value $ 1.39 $ 0.27 $ 1.39 $ 0.27 Restricted Stock Units The Company has granted restricted stock units ("RSUs") to executive officers and employees pursuant to the 2010 Plan from time to time. There is no direct cost to the recipients of RSUs, except for any applicable taxes. Each RSU award that was granted to the Company's executive officers and employees represents one share of common stock. Each year following the annual vesting date, between January 1st and March 15th, the Company will issue common stock for each vested RSU. During the period when the RSU is vested but not distributed, the RSUs cannot be transferred and the grantee has no voting rights. If the Company declares a dividend, RSU recipients will receive payment based upon the percentage of RSUs that has vested prior to the date of declaration. The costs of the awards, determined as the fair market value of the shares on the grant date, are expensed per the vesting schedule outlined in the award. Based on historical experience of option cancellations, the Company has estimated an annualized forfeiture rate of 17.61%. Forfeiture rates are adjusted over the requisite service period when actual forfeitures differ, or are expected to differ, from the estimate. The stock-based compensation expense associated with the RSUs has been recorded in the statement of operations and in additional paid-in-capital on the balance sheets is as follows: Three Months Ended Six Months Ended 2015 2016 2015 2016 Stock compensation expense — RSUs $ 50 $ — $ 84 $ — The following table summarizes RSU activity from October 1, 2015 through March 31, 2016: Shares Weighted Vested and not distributed balance at October 1, 2015 131,128 $ 1.57 Changes during the period: RSUs granted — — RSUs converted to common stock (131,128 ) 1.57 Vested and not distributed — — Non-vested and outstanding RSU balance at March 31, 2016 — $ — 2005 Employee Stock Purchase Plan The Company's 2005 Employee Stock Purchase Plan (the "Purchase Plan") was adopted by its board of directors and approved by its stockholders on March 20, 2007. The Purchase Plan became effective upon the closing of the Company's initial public offering. The Purchase Plan is intended to qualify as an employee stock purchase plan within the meaning of Section 423 of the Internal Revenue Code. Under the Purchase Plan, eligible employees may contribute up to 15% of their eligible earnings for the period of that offering to be withheld for the purchase of common stock under the Purchase Plan. The employee's purchase price is equal to the lower of: 85% of the fair market value per share on the start date of the offering period in which the employee is enrolled or 85% of the fair market value per share on the semi-annual purchase date. The Purchase Plan imposes a limitation upon a participant's right to acquire common stock if immediately after the purchase the employee would own 5% or more of the total combined voting power or value of the Company's common stock or of any of its affiliates. The Purchase Plan provides for an automatic rollover when the purchase price for a new offering period is lower than previously established purchase price(s). The Purchase Plan also provides for a one-time election that allows an employee the opportunity to enroll into a new offering period when the new offering is higher than their current offering price. This election must be made within 30 days from the start of a new offering period. Offering periods are twenty-seven months in length. The compensation charge/(credit) in connection with the Purchase Plan for the three and six months ended March 31, 2016 was $0. In comparison, for the three and six months ended March 31, 2015, the Company expensed $1 and $4, respectively. An aggregate of 550,000 shares of common stock are reserved for issuance pursuant to purchase rights to be granted to the Company's eligible employees under the Purchase Plan. The Purchase Plan shares are replenished annually on the first day of each calendar year by virtue of an evergreen provision. The provision allows for share replenishment equal to the lesser of 1% of the total number of shares of common stock outstanding on that date or 25,000 shares. As of March 31, 2015 and 2016, a total of 401,262 and 395,382 shares, respectively, were reserved and available for issuance under the Purchase Plan. As of March 31, 2015 and 2016, the Company has issued 123,738 and 154,618 shares, respectively, under the Purchase Plan.

Income Taxes [Abstract]
Income Taxes	5. Income Taxes The Company accounts for income taxes under FASB ASC 740-10-25 ("ASC 740-10-25"), Accounting for Income Taxes. Under ASC 740-10-25, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under ASC 740-10-25, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company files U.S. federal and state tax returns and has determined that its major tax jurisdictions are the United States and Connecticut. The tax years through 2015 remain open and subject to examination by the appropriate governmental agencies in the United States and Connecticut. Section 382 of the Internal Revenue Code imposes limitations on the use of U.S. federal net operating losses ("NOLs") if there is more than a 50% change in ownership in the Company within a three-year period. The Company's NOLs will continue to be available to offset taxable income (until such NOLs are either used or expire) subject to the Section 382 annual limitation. If the Section 382 annual limitation amount is not fully utilized in a particular tax year, then the unused portion from that particular tax year will be added to the Section 382 annual limitation in subsequent years. The Company has determined that an ownership change, under Section 382, occurred as of December 31, 2013 and therefore, the ability to utilize its current NOLs is further limited. The Company has approximately $31 million of U.S. federal NOLs and approximately $133 million of state NOLs, which, if not used, expire beginning in 2025 through 2035. The Company's effective tax rate for the three and six months ended March 31, 2015 and 2016 was 0% and differs from the federal statutory rate of 34% due to net operating losses. A valuation allowance for the full amount of the deferred tax assets has been established as of September 30, 2015 and March 31, 2016.

Financings [Abstract]
Financings	7. Financings April 2015 Underwritten Public Offering On April 20, 2015, the Company completed an underwritten public offering of 37,500,000 shares of its common stock, which included the full exercise of the underwriter's option to purchase 4,891,304 shares to cover overallotments, at a price to the public of $0.92 per share. The Company received net proceeds from this offering, after deducting underwriting discounts, commissions and expenses of $32,149. July 2014 Equity Line Purchase Agreement On July 25, 2014, the Company entered into a purchase agreement (the "Purchase Agreement"), together with a registration rights agreement (the "Registration Rights Agreement") with Lincoln Park Capital Fund, LLC ("LPC"). Under the terms, and subject to the conditions of the Purchase Agreement, the Company had the right to sell to LPC, and LPC was obligated to purchase, up to $15 million in shares of common stock, subject to certain limitations, from time to time over the 36-month period commencing on the date that a registration statement, which the Company agreed to file with the SEC pursuant to the Registration Rights Agreement, was declared effective by the SEC and a final prospectus in connection therewith was filed. The Company's registration statement was declared effective on September 2, 2014. The Company was obligated, within twenty (20) calendar days, to file with the SEC an initial Registration Statement covering the maximum number of Registrable Securities permitted to be included thereon in accordance with applicable SEC rules, regulations and interpretations so as to permit the resale of such Registrable Securities by LPC under Rule 415 under the Securities Act at then prevailing market prices (and not fixed prices), as mutually determined by both the Company and LPC in consultation with their respective legal counsel, subject to the aggregate number of authorized shares of the Company's Common Stock then available for issuance in its Certificate of Incorporation. The Company was required to use its commercially reasonable efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated under the Securities Act and available for the resale by LPC of all of the Registrable Securities covered thereby at all times until the date on which LPC shall have resold all the Registrable Securities covered thereby and no available amount remained under the Purchase Agreement. The Company could direct LPC, at its sole discretion and subject to certain conditions, to purchase up to 150,000 shares of common stock in any business day, increasing to amounts of up to 250,000 shares, depending upon the closing sale price of the common stock. In addition, the Company could direct LPC to purchase additional shares as accelerated purchases if, on the date of a regular purchase, the closing sale price of the common stock was not below $2.50 per share (subject to adjustment). The purchase price of shares of common stock purchased under the Purchase Agreement were based on the prevailing market prices of such shares at the time of sales, but in no event could the Company sell shares to LPC on a day when the closing sale price of the common stock was less than a floor price of $1.50 per share (subject to adjustment). The Company could control the timing and amount of any sales of common stock to LPC under the Purchase Agreement. As consideration for LPC's commitment to purchase shares of common stock pursuant to the Purchase Agreement, the Company issued to LPC 95,000 shares of Common Stock as commitment shares, with a fair market value of $189, which is recorded as the cost of capital in additional paid in capital. In aggregate, the Company has sold 750,000 shares of common stock pursuant to the Purchase Agreement, and received proceeds, net of expenses, of $1,161. On April 14, 2015, the Company provided written notice of termination of the Purchase Agreement pursuant to the terms of the agreement. The termination became effective on April 16, 2015. May 2013 At-the-Market Issuance Sales Agreement In May 2013, the Company entered into an At-the-Market Issuance Sales Agreement (the "Sales Agreement") with MLV & Co. LLC ("MLV"), under which the Company may initially issue and sell shares of common stock having aggregate sales proceeds of up to an additional $3,200 from time to time through MLV as the Company's sales agent. In aggregate, the Company has sold 2,607,535 shares of common stock pursuant to the Sales Agreement and received proceeds, net of sales agent commissions and expenses, of $4,700. June 2012 Private Placement In June 2012, the Company completed a private placement (the "2012 Private Placement") of an aggregate of 4,250,020 shares of the Company's common stock, 3,605,607 shares of the Company's Series B Convertible Preferred Stock and warrants to purchase an aggregate of 2,749,469 shares of common stock at an exercise price of $2.66 per share. For each unit consisting of either a share of common stock or Series B Preferred Stock and a warrant to purchase 0.35 of a share of common stock, the purchasers in the 2012 Private Placement paid a negotiated price of $2.355. The warrants were immediately exercisable and will expire on June 26, 2017, five years from the original issuance date of June 27, 2012. The Company received net proceeds, after deducting placement agents' fees and other transaction expenses, of approximately $17,100 from the 2012 Private Placement. Each share of Series B Preferred Stock was convertible into one share of the Company's common stock at any time at the option of the holder, except that the securities purchase agreement that the Company entered into in connection with the 2012 Private Placement (the "Securities Purchase Agreement") provides that a holder would be prohibited from converting shares of Series B Preferred Stock into shares of common stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than 9.98% of the total number of shares of common stock then issued and outstanding. In the event of the Company's liquidation, dissolution or winding up, holders of the Series B Preferred Stock will receive a payment equal to $0.01 per share of Series B Preferred Stock before any proceeds are distributed to the holders of common stock. After the payment of this preferential amount, and subject to the rights of holders of any class or series of capital stock specifically ranking by its terms senior to the Series B Preferred Stock holders of Series B Preferred Stock would participate ratably in the distribution of any remaining assets with the common stock and any other class or series of capital stock that participates with the common stock in such distributions. Shares of Series B Preferred Stock generally have no voting rights, except as required by law and except that the consent of the holders of a majority of the outstanding Series B Preferred Stock would be required to amend the terms of the Series B Preferred Stock. Holders of Series B Preferred Stock were entitled to receive, and the Company was required to pay, dividends on shares of the Series B Preferred Stock equal (on an as-if-converted-to-common-stock basis) to and in the same form as dividends (other than dividends in the form of common stock) actually paid on shares of the common stock when, as and if such dividends (other than dividends in the form of common stock) were paid on shares of the common stock. All Series B Preferred Stock has been converted into common stock and none remains outstanding. As required by the Securities Purchase Agreement, the Company filed a Registration Statement on Form S-3 (the "Registration Statement") with the Securities and Exchange Commission (the "SEC") on July 27, 2012, which was within 30 days after the closing of the 2012 Private Placement. The Registration Statement, which was declared effective on August 13, 2012, registers the resale of the shares of common stock and Series B Preferred Stock issued and sold in the 2012 Private Placement, the shares of common stock issuable upon conversion of the Series B Preferred Stock issued and sold in the 2012 Private Placement, and the shares of common stock issuable upon exercise of the warrants issued and sold in the 2012 Private Placement. Pursuant to the terms of the Securities Purchase Agreement, the Company agreed to pay liquidated damages to the purchasers in the 2012 Private Placement if, after effectiveness of the Registration Statement and subject to certain specified exceptions, the Company suspends the use of the Registration Statement or the Registration Statement ceases to remain continuously effective as to all the securities for which it is required to be effective (each such event, a "Registration Default"). Subject to specified exceptions, for each 30-day period or portion thereof during which a Registration Default remains uncured, the Company is obligated to pay liquidated damages to each purchaser in cash in an amount equal to 1.0% of the aggregate purchase price paid by each such purchaser in the 2012 Private Placement, up to a maximum of 8.0% of such aggregate purchase price. As of the date of these financial statements, the Company does not believe that it is probable that it will be obligated to pay any such liquidated damages. Accordingly, the Company has not established an accrual for liquidated damages. In the event that the Company enters into a merger or change of control transaction, the holders of the warrants issued in the 2012 Private Placement will be entitled to receive consideration as if they had exercised the warrants immediately prior to such transaction, or they may require the Company to purchase the unexercised warrants at the Black-Scholes value (as defined in the warrant) of the warrant on the date of such transaction. The holders have up to 30 days following any such transaction to exercise this right. As a result of this provision, the Company recognizes the warrants as liabilities at their fair value on each reporting date. At March 31, 2016, the fair value of the warrant liability determined utilizing the Black-Scholes valuation model was approximately $3. In comparison, the fair value of the warrant liability at September 30, 2015 was $5. During the three and six months ended March 31, 2016, the Company recorded an adjustment to fair value of common stock warrant liability of $2 within Other income, to reflect a decrease in the valuation of the warrants from September 30, 2015 to March 31, 2016. The following summarizes the changes in value of the warrant liability from September 30, 2015 through March 31, 2016: Balance at September 30, 2015 $ 5 Decrease in fair value of common stock warrant liability (2 ) Balance at March 31, 2016 $ 3 May 2011 Registered Direct Offering In May 2011, the Company completed a registered direct offering (the "May 2011 Offering") of an aggregate of 3,018,736 shares of the Company's common stock, 1,813,944 shares of the Company's Series A Preferred Stock and warrants to purchase 2,256,929 shares of the Company's common stock. The shares and warrants were sold in units consisting of (i) one share of common stock and (ii) one warrant to purchase 0.1625 of a share of common stock, at an exercise price of $9.92 per share of the Company's common stock. However, one investor also purchased units consisting of one share of Series A Preferred Stock and a warrant to purchase 0.1625 of a share of common stock. No fractional warrants were issued. Each unit was sold at a price of $8.64 per unit. These units were not issued or certificated. The shares and warrants were immediately separated. The warrants will expire on May 17, 2016, five years from the original issuance date of May 18, 2011. The Company received net proceeds, after deducting placement agents' fees and other offering expenses, of approximately $28,000 from the May 2011 Offering. Each share of Series A Preferred Stock was convertible into one quarter of a share of the Company's common stock at any time at the option of the holder, provided that the holder was prohibited from converting the shares of Series A Preferred Stock into shares of the Company's common stock if, as a result of such conversion, the holder, together with its affiliates, would beneficially own more than 9.98% of the total number of shares of the Company's common stock then issued and outstanding. All Series A Preferred Stock has been converted into common stock and none remains outstanding. In the event that the Company enters into a merger or change of control transaction, the holders of the warrants issued in the May 2011 Offering will be entitled to receive consideration as if they had exercised the warrants immediately prior to such transaction, or they may require the Company to purchase the unexercised warrants at the Black-Scholes value (as defined in the warrant) of the warrant on the date of such transaction. As per terms of the warrant, the holders have up to 30 days following any such transaction to exercise this right. As a result of this provision, the Company recognizes the warrants as liabilities at their fair value on each reporting date. At March 31, 2016, the fair value of the warrant liability determined utilizing the Black-Scholes valuation model was approximately $0. In comparison, the fair value of the warrant liability at September 30, 2015 was $0. Fair Value Assumptions Used in Accounting for Warrant Liability The Company has determined its warrant liability to be a Level 3 fair value measurement and used the Black-Scholes valuation model to calculate, as of March 31, 2016, the fair value of the warrants issued in the 2012 Private Placement and the May 2011 Offering. As of March 31, 2016, the Company estimated such fair value using the following assumptions: June 2012 Private Placement March 31, 2016 Stock price $ 0.33 Exercise price $ 2.66 Risk-free interest rate 0.59 % Expected remaining term (years) 1.24 Expected volatility 75 % Dividend yield — Warrants outstanding 2,749,469 May 2011 Offering March 31, 2016 Stock price $ 0.33 Exercise price $ 9.92 Risk-free interest rate 0.18 % Expected remaining term (years) 0.13 Expected volatility 58 % Dividend yield — Warrants outstanding 2,256,929 Risk-Free Interest Rate. Term of Warrants. Expected Volatility. Dividend Yield. Participating Securities If at any time the Company grants, issues or sells securities or other property to holders of any class of common stock, the holders of the warrants are entitled to also acquire those same securities as if they held the number of shares of common stock acquirable upon complete exercise of the warrants. As such, given that the warrant holders will participate fully on any dividends or dividend equivalents, the Company determined that the warrants are participating securities and therefore are subject to ASC 260-10-55 earnings per share. These securities were excluded from the three and six months ended March 31, 2015 and 2016 loss per share calculation since their inclusion would be anti-dilutive.

Commitments [Abstract]
Commitments	8. Commitments Leases As of March 31, 2016, the Company leased three facilities in Danbury, Connecticut. The Company extended its lease for laboratory space in January 2016 for an additional three months through April 30, 2016. This lease provides for annual basic lease payments of $68, plus the annual Consumers Price Index ("CPI") increase for October, not to exceed 6%, plus operating expenses. This lease expired on April 30, 2016 and was not renewed. The Company also extended its lease agreement for additional office space adjacent to its laboratory space in January 2016 for an additional three months through April 30, 2016. This lease provides for annual basic lease payments of $31, plus the annual CPI increase for October, not to exceed 6%, plus operating expenses. This lease expired on April 30, 2016 and was not renewed. In November 2013, the Company renewed its lease for its corporate office for five years. This lease provides for annual basic lease payments of $388, plus the annual CPI increase for May, not to exceed 6%, plus operating expenses. Rent expense for the three and six months ended March 31, 2016 was $168 and $335, respectively. In comparison, rent expense for the three and six months ended March 31, 2015, was $167 and $333, respectively. Other Commitments The Company has entered into certain licensing and collaboration agreements for products currently under development. The Company may be obligated in future periods to make additional payments, which would become due and payable only upon the achievement of certain research and development, regulatory, and approval milestones. The specific timing of such milestones cannot be predicted and depend upon future discretionary research and clinical developments, as well as, regulatory agency actions. Further, under the terms of certain agreements the Company may be obligated to pay commercial milestones contingent upon the realization of sales revenues and sublicense revenues. Due to the long range nature of such commercial milestones, they are neither probable at this time nor predictable, and consequently are not considered contingent milestone payment amounts.

Restructuring [Abstract]
Restructuring	9. Restructuring The Company follows the provisions of ASC Topic 420, "Exit or Disposal Cost Obligations", which addresses financial accounting and reporting for costs associated with exit or disposal activities. The statement requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. The Company records liabilities that primarily include severance and other costs related to employee benefits, as appropriate. Restructuring and other costs were $3,000 for the three months ended March 31, 2016 and $3,300 for the six months ended March 31, 2016, and represent severance and other costs related to employee benefits. These costs were expensed in the three and six months ended March 31, 2016, and are aggregated in the Condensed Consolidated Statement of Operations on the Research and development and General and administrative expense lines. The restructuring plan is primarily designed to reduce infrastructure and operational costs as the Company continues to explores its strategic alternatives. In comparison, restructuring and other costs were $0 for the three and six months ended March 31, 2015. The following summarizes the activities related to the restructuring accruals on the balance sheet: Current: Total Accrued restructuring balance at September 30, 2015 $90 Restructuring charges 1,425 Amortization (21) Accrued restructuring balance at March 31, 2016 $1,404 Restructuring and other long term liabilities: Accrued restructuring balance at September 30, 2015 $ 54 Restructuring charges 1,087 Amortization (176) Restructuring and other long term liabilities balance at March 31, 2016 $ 965

Convertible preferred stock, terms of conversion				Each share of Series B Preferred Stock was convertible into one share of the Company's common stock at any time at the option of the holder, except that the securities purchase agreement that the Company entered into in connection with the 2012 Private Placement (the "Securities Purchase Agreement") provides that a holder would be prohibited from converting shares of Series B Preferred Stock into shares of common stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than 9.98% of the total number of shares of common stock then issued and outstanding. In the event of the Company's liquidation, dissolution or winding up, holders of the Series B Preferred Stock will receive a payment equal to $0.01 per share of Series B Preferred Stock before any proceeds are distributed to the holders of common stock. After the payment of this preferential amount, and subject to the rights of holders of any class or series of capital stock specifically ranking by its terms senior to the Series B Preferred Stock holders of Series B Preferred Stock would participate ratably in the distribution of any remaining assets with the common stock and any other class or series of capital stock that participates with the common stock in such distributions. Shares of Series B Preferred Stock generally have no voting rights, except as required by law and except that the consent of the holders of a majority of the outstanding Series B Preferred Stock would be required to amend the terms of the Series B Preferred Stock. Holders of Series B Preferred Stock were entitled to receive, and the Company was required to pay, dividends on shares of the Series B Preferred Stock equal (on an as-if-converted-to-common-stock basis) to and in the same form as dividends (other than dividends in the form of common stock) actually paid on shares of the common stock when, as and if such dividends (other than dividends in the form of common stock) were paid on shares of the common stock. All Series B Preferred Stock has been converted into common stock and none remains outstanding.
