 &lt;b&gt;AbbVie Collaboration&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 On November&amp;#xA0;27, 2006, the Company entered into a Collaborative
 Development and License Agreement (the &amp;#x201C;AbbVie
 Agreement&amp;#x201D;) with Abbott Laboratories to identify, develop and
 commercialize HCV&amp;#xA0;NS3 and NS3/4A protease inhibitor compounds,
 including paritaprevir (previously known as ABT-450). The
 agreement, which was amended in January and December 2009, was
 assigned by Abbott to AbbVie Inc. on January&amp;#xA0;1, 2013 in
 connection with Abbott&amp;#x2019;s transfer of its research-based
 pharmaceuticals business to AbbVie. The agreement was subsequently
 amended further in October 2014 and March 2015.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Under the terms of the AbbVie Agreement, as amended, AbbVie paid to
 the Company upfront license payments and FTE reimbursements to fund
 research activities. The Company is also eligible to receive
 milestone payments for the successful development by AbbVie of one
 or more HCV compounds as well as annually tiered royalties per
 product ranging from the low double digits up to twenty percent, or
 on a blended basis from the low double digits up to the high teens,
 on net sales by AbbVie allocated to the collaboration&amp;#x2019;s
 protease inhibitors. Under the terms of the agreement, as amended
 in October 2014, 30% of net sales of a 3-DAA regimen containing
 paritaprevir will be allocated to paritaprevir, and 45% of net
 sales of a 2-DAA regimen containing paritaprevir will be allocated
 to paritaprevir. For ABT-493, 50% of net sales of a 2-DAA regimen
 containing ABT-493 will be allocated to ABT-493, and 33&lt;sup style="VERTICAL-ALIGN: top"&gt;&amp;#xA0;1&lt;/sup&gt;&amp;#x2044;&lt;sub style="VERTICAL-ALIGN: bottom"&gt;3&lt;/sub&gt;% of net sales of a 3-DAA regimen
 containing ABT-493 will be allocated to ABT-493. If there is any
 active ingredient other than DAA&amp;#x2019;s in any ABT-493-containing
 regimen sold by AbbVie, there will be a further adjustment to net
 sales based on the relative value of the non-DAA ingredient.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Deliverables under the AbbVie Agreement included a license,
 research services and participation on a steering committee. The
 Company concluded that all deliverables under the AbbVie Agreement
 should be treated as a single unit of accounting. Accordingly,
 revenue was recognized using the proportional performance model
 over the period during which the Company performed research
 services. The Company completed all remaining service obligations
 under the agreement as of June 2011. All milestone payments
 received after June 2011 are recognized as revenue when the
 respective milestone is achieved by AbbVie.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Through September&amp;#xA0;30, 2014, the Company had received upfront
 license payments, proceeds from a sale of preferred stock, research
 funding payment, and milestone payments totaling $160,000 from
 AbbVie.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 In December 2014, the Company earned and recognized as revenue a
 $75,000 milestone amount due from AbbVie as a result of U.S.
 regulatory approval by the FDA for AbbVie&amp;#x2019;s first treatment
 regimen containing a collaboration compound. In January 2015, the
 Company earned and recognized as revenue a $50,000 milestone
 payment from AbbVie upon commercialization regulatory approval of
 VIEKIRAX in Europe.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 As a result, during the three and six months ended March&amp;#xA0;31,
 2015, the Company recognized milestone revenue of $50,000 and
 $125,000, respectively. The Company&amp;#x2019;s first product,
 paritaprevir, was a part of AbbVie&amp;#x2019;s new treatment regimen
 for HCV approved by the FDA on December&amp;#xA0;19, 2014. During the
 three and six months ended March&amp;#xA0;31, 2015, the Company
 recognized royalty revenue of $6,961 and $8,353, respectively.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 As of March&amp;#xA0;31, 2015, the Company was eligible to receive
 additional milestone payments totaling up to $30,000 upon
 AbbVie&amp;#x2019;s achievement of commercialization regulatory approval
 of a paritaprevir-containing regimen in Japan. The Company is also
 eligible to receive additional milestone payments totaling up to
 $80,000 upon AbbVie&amp;#x2019;s achievement of similar
 commercialization regulatory approval milestones in the U.S. and
 other selected world markets for each additional protease inhibitor
 commercialized by AbbVie.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;Novartis Collaboration&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 On February&amp;#xA0;16, 2012, the Company entered into a license and
 collaboration agreement with Novartis (the&amp;#xA0;&amp;#x201C;Novartis
 Agreement&amp;#x201D;) for the development, manufacture and
 commercialization of its lead development candidate, EDP-239, from
 its NS5A&amp;#xA0;HCV inhibitor program.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 On September&amp;#xA0;30, 2014 the Company entered into an amendment to
 its 2012 collaboration and license agreement with Novartis to
 return to the Company full rights to its NS5A inhibitor program,
 including EDP-239, and to transition the proof-of-concept study to
 the Company. The Company owes no future payments to Novartis in
 connection with this transfer except for any unused drug product or
 ingredients that the Company may choose to buy from Novartis.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;NIAID Contract&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 On September&amp;#xA0;30, 2011, the Company entered into a contract
 with the National Institute of Allergy and Infectious Diseases
 (&amp;#x201C;NIAID&amp;#x201D;), a division of the National Institutes of
 Health (&amp;#x201C;NIH&amp;#x201D;), which contract provided for up to
 $42,700 in potential development funding to the Company over a
 five-year period. Under this contract NIAID has funded the
 preclinical and clinical development of a bridged bicyclic
 antibiotic to be used as a medical countermeasure against multiple
 biodefense Category A and B bacteria.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Funding originally paid or committed by NIAID has totaled
 approximately $23,500. In December 2014, the company communicated
 to NIAID its strategic decision not to continue commercial
 development of the antibiotic candidate for non-biodefense
 indications. In February 2015, NIAID and the Company amended the
 contract to decrease the total committed funding to $21,000 and its
 completion date to August 2015 upon the Company&amp;#x2019;s delivery of
 the study report for the Phase 1 clinical study.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The Company recognizes revenue under this agreement as development
 services are performed in accordance with the funding agreement.
 During the three months ended March&amp;#xA0;31, 2015 and 2014, $406
 and $2,160 of revenue, respectively, was recognized under this
 agreement. During the six months ended March&amp;#xA0;31, 2015 and
 2014, the Company recognized revenue of $1,512 and $3,053,
 respectively.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 In March 2015 the Company amended its lease of office and
 laboratory space to expand the rented space and extend the lease
 term beginning in the fourth fiscal quarter of 2015. As amended,
 the lease expires in September 2022. Payment escalation as
 specified in the lease agreement is accrued such that rent expense
 is recognized on a straight-line basis over the term of occupancy.
 The Company recorded rent expense of $243 and $237 for the three
 months ended March&amp;#xA0;31, 2015 and 2014, respectively, and $480
 and $474 for the six months ended March&amp;#xA0;31, 2015 and 2014,
 respectively.&lt;/p&gt;

 In connection with the lease, the Company has outstanding a $608
 and $436 letter of credit, collateralized by a money market
 account, as of March&amp;#xA0;31, 2015 and September&amp;#xA0;30, 2014,
 respectively. The Company classified such amounts as restricted
 cash.&lt;/p&gt;

 &lt;b&gt;Intellectual Property Licenses&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 The Company has a non-exclusive intellectual property license
 agreement with a third party, under which the Company is required
 to pay $200 in fiscal 2015 and (1)&amp;#xA0;annual maintenance fees of
 $105 for each year that the agreement remains in effect, commencing
 on the first anniversary of the agreement, in order to maintain the
 right to use the license, and (2)&amp;#xA0;a one-time fee of $50 in
 each circumstance in which the Company provides the licensed
 intellectual property to one of its collaborators with the prior
 consent of the licensor.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 The Company also has a non-exclusive license with respect to
 patents it uses in its HCV research. Under the license, the Company
 is obligated to pay milestones totaling up to $5,000, plus low
 single digit royalties, for the development and regulatory approval
 of each HCV product outside of the Company&amp;#x2019;s collaboration
 with AbbVie and any other collaboration it may enter into in the
 future with a partner that has already licensed these patents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;Litigation and Contingencies Related to Use of Intellectual
 Property&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 From time to time, the Company may become subject to legal
 proceedings, claims and litigation arising in the ordinary course
 of business. The Company currently is not a party to any threatened
 or pending litigation. However, third parties might allege that the
 Company or its collaborators are infringing their patent rights or
 that the Company is otherwise violating their intellectual property
 rights. Such third parties may resort to litigation against the
 Company or its collaborators, which the Company has agreed to
 indemnify. With respect to some of these patents, the Company
 expects that it will be required to obtain licenses and could be
 required to pay license fees or royalties, or both. These licenses
 may not be available on acceptable terms, or at all. A costly
 license, or inability to obtain a necessary license, could have a
 material adverse effect on the Company&amp;#x2019;s financial condition,
 results of operations or cash flows. The Company accrues contingent
 liabilities when it is probable that future expenditures will be
 made and such expenditures can be reasonably estimated.&lt;/p&gt;

 &lt;b&gt;Revenue Recognition&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 The Company&amp;#x2019;s revenue has been generated primarily through
 collaborative research and license agreements. The terms of these
 agreements contain multiple deliverables, which may include
 (i)&amp;#xA0;licenses, (ii)&amp;#xA0;research and development activities,
 and (iii)&amp;#xA0;participation in joint research and development
 steering committees. The terms of these agreements may include
 nonrefundable upfront license fees, payments for research and
 development activities, payments based upon the achievement of
 certain milestones, and royalty payments based on product sales
 derived from the collaboration. In all instances, revenue is
 recognized only when the price is fixed or determinable, persuasive
 evidence of an arrangement exists, delivery has occurred or the
 services have been rendered, collectibility of the resulting
 receivable is reasonably assured, and the Company has fulfilled its
 performance obligations under the contract.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 For agreements entered into prior to October&amp;#xA0;1, 2011, the
 Company evaluated license agreements with multiple deliverables to
 determine if the deliverable elements could be recognized
 separately by considering (i)&amp;#xA0;if the delivered elements
 (typically the license) had standalone value to the customer,
 (ii)&amp;#xA0;if the fair value of any undelivered elements (typically
 the research and development services and the steering committee
 activities) could be determined based on vendor-specific objective
 evidence (&amp;#x201C;VSOE&amp;#x201D;) or vendor objective evidence
 (&amp;#x201C;VOE&amp;#x201D;), and (iii)&amp;#xA0;if the arrangement included a
 general right of return relative to the delivered item, the
 delivery or performance of the undelivered item was considered
 probable and substantially within the control of the Company. VSOE
 of fair value was based on the consistent price of a deliverable
 when the Company regularly sold it on a standalone
 basis.&amp;#xA0;Alternatively, VOE was based upon third-party objective
 evidence of fair value. If the delivered elements had value on a
 standalone basis and the fair value of the undelivered elements
 could be determined based on VSOE or VOE, revenues of such elements
 were then accounted for separately as delivered with arrangement
 consideration allocated to the delivered elements based on the
 residual value method. If either (i)&amp;#xA0;the delivered elements
 were considered to not have standalone value or (ii)&amp;#xA0;VSOE or
 VOE of fair value for any of the undelivered elements could not be
 determined, the arrangement was accounted for as a single unit of
 accounting and all payments received were recognized as revenue
 over the estimated period of performance of the entire
 arrangement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 On October&amp;#xA0;1, 2011, the Company adopted Accounting Standards
 Update (&amp;#x201C;ASU&amp;#x201D;) No.&amp;#xA0;2009-13,
 &lt;i&gt;Multiple-Deliverable Revenue Arrangements&lt;/i&gt; (&amp;#x201C;ASU
 2009-13&amp;#x201D;). This guidance, which applies to multiple-element
 arrangements entered into or materially modified on or after
 October&amp;#xA0;1, 2011, amends the criteria for separating and
 allocating consideration in a multiple-element arrangement by
 modifying the fair value requirements for revenue recognition and
 eliminating the use of the residual value method. The selling
 prices of deliverables under the arrangement may be derived using
 third-party evidence (&amp;#x201C;TPE&amp;#x201D;) or a best estimate of
 selling price (&amp;#x201C;BESP&amp;#x201D;), if VSOE is not available. The
 objective of BESP is to determine the price at which the Company
 would transact a sale if the element within the license agreement
 was sold on a standalone basis. Establishing BESP involves
 management&amp;#x2019;s judgment and considers multiple factors,
 including market conditions and company-specific factors including
 those factors contemplated in negotiating the agreements as well as
 internally developed models that include assumptions related to
 market opportunity, discounted cash flows, estimated development
 costs, probability of success, and the time needed to commercialize
 a product candidate pursuant to the license. In validating the
 Company&amp;#x2019;s BESP, the Company considers whether changes in key
 assumptions used to determine the BESP will have a significant
 effect on the allocation of the arrangement consideration between
 the multiple deliverables. Deliverables under the arrangement are
 separate units of accounting if (i)&amp;#xA0;the delivered item has
 value to the customer on a standalone basis, and (ii)&amp;#xA0;if the
 arrangement includes a general right of return relative to the
 delivered item, delivery or performance of the undelivered item is
 considered probable and substantially within the control of the
 Company. The arrangement consideration that is fixed or
 determinable at the inception of the arrangement is allocated to
 the separate units of accounting based on their relative selling
 prices. The appropriate revenue recognition model is applied to
 each element, and revenue is accordingly recognized as each element
 is delivered. The Company may exercise significant judgment in
 determining whether a deliverable is a separate unit of accounting.
 The Company elected to adopt ASU 2009-13 prospectively as of
 October&amp;#xA0;1, 2011.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 In determining the separate units of accounting, the Company
 evaluates whether the license has standalone value to the
 collaborator based on consideration of the relevant facts and
 circumstances for each arrangement. Factors considered in this
 determination include the research and development capabilities of
 the collaborator and the availability of relevant research
 expertise in the marketplace. In addition, the Company considers
 whether or not (i)&amp;#xA0;the collaborator can use the license for
 its intended purpose without the receipt of the remaining
 deliverables, (ii)&amp;#xA0;the value of the license is dependent on
 the undelivered items, and (iii)&amp;#xA0;the collaborator or other
 vendors can provide the undelivered items.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Under a collaborative research and license agreement, a steering
 committee is typically responsible for overseeing the general
 working relationships, determining the protocols to be followed in
 the research and development performed, and evaluating the results
 from the continued development of the product in order to determine
 the clinical studies to be performed. The Company evaluates whether
 its participation in joint research and development steering
 committees is a substantive obligation or whether the services are
 considered inconsequential or perfunctory. The Company&amp;#x2019;s
 participation on a steering committee is considered
 &amp;#x201C;participatory&amp;#x201D; and therefore accounted for as a
 separate element when the collaborator requires the participation
 of the Company to ensure all elements of an arrangement are
 maximized. Steering committee services that are considered
 participatory are combined with other research services or
 performance obligations required under an arrangement, if any, in
 determining the level of effort required in an arrangement and the
 period over which the Company expects to complete its aggregate
 performance obligations. Alternatively, the Company&amp;#x2019;s
 participation on a steering committee is considered
 &amp;#x201C;protective&amp;#x201D; and therefore not accounted for as a
 separate element in a case where the Company can exercise or
 control when to be involved at its own discretion. Factors the
 Company considers in determining if its participation in a joint
 steering committee is participating or protective include:
 (i)&amp;#xA0;which party negotiated or requested the steering
 committee, (ii)&amp;#xA0;how frequently the steering committee meets,
 (iii)&amp;#xA0;whether or not there are any penalties or other recourse
 if the Company does not attend the steering committee meetings,
 (iv)&amp;#xA0;which party has decision making authority on the steering
 committee, and (v)&amp;#xA0;whether or not the collaborator has the
 requisite experience and expertise associated with the research and
 development of the licensed intellectual property.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 For all periods presented, whenever the Company determines that an
 element is delivered over a period of time, revenue is recognized
 using either a proportional performance model or a straight-line
 model over the period of performance, which is typically the
 research and development term. Full-time equivalents
 (&amp;#x201C;FTEs&amp;#x201D;) are typically used as the measure of
 performance. At each reporting period, the Company reassesses its
 cumulative measure of performance and makes appropriate
 adjustments, if necessary. The Company recognizes revenue using the
 proportional performance model whenever the Company can make
 reasonably reliable estimates of the level of effort required to
 complete its performance obligations under an arrangement. Revenue
 recognized under the proportional performance model at each
 reporting period is determined by multiplying the total expected
 payments under the contract (excluding royalties and payments
 contingent upon achievement of milestones) by the ratio of the
 level of effort incurred to date to the estimated total level of
 effort required to complete the performance obligations under the
 arrangement. Revenue is limited to the lesser of the cumulative
 amount of payments received or the cumulative amount of revenue
 earned, as determined using the proportional performance model as
 of each reporting period. Alternatively, if the Company cannot make
 reasonably reliable estimates of the level of effort required to
 complete its performance obligations under an arrangement, then
 revenue under the arrangement is recognized on a straight-line
 basis over the period expected to complete the Company&amp;#x2019;s
 performance obligations. If and when a contingent milestone payment
 is earned, the additional consideration to be received is allocated
 to the separate units of accounting in the arrangement based on
 their relative selling prices at the inception of the arrangement.
 Revenue is limited to the lesser of the cumulative amount of
 payments received or the cumulative amount of revenue earned, as
 determined on a straight-line basis as of the period end date. If
 the Company cannot reasonably estimate when its performance
 obligation period ends, then revenue is deferred until the Company
 can reasonably estimate when the performance obligation period
 ends.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Royalty revenue is recognized based on contractual terms when
 reported sales are reliably measurable and collectibility is
 reasonably assured, provided that there are no performance
 obligations then remaining.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 During the three and six months ended March&amp;#xA0;31, 2015 and 2014,
 the Company also generated revenue from a government contract,
 under which the Company is reimbursed for certain allowable costs
 for the funded project. Revenue from the government contract is
 recognized when the related service is performed. The related costs
 incurred by the Company under the government contract are included
 in research and development expenses in the statements of
 operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 Amounts received prior to satisfying all revenue recognition
 criteria are recorded as deferred revenue in the accompanying
 consolidated balance sheets. Amounts not expected to be recognized
 as revenue within the next twelve months of the consolidated
 balance sheet date are classified as long-term deferred
 revenue.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt"&gt;
 In the event that a collaborative research and license agreement is
 terminated and the Company then has no further performance
 obligations, the Company recognizes as revenue any amounts that had
 not previously been recorded as revenue but were classified as
 deferred revenue at the date of such termination.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 The preparation of consolidated financial statements in conformity
 with GAAP requires management to make estimates and assumptions
 that affect the reported amounts of assets and liabilities, the
 disclosure of contingent assets and liabilities at the date of the
 consolidated financial statements, and the reported amounts of
 revenues and expenses during the reporting period. Significant
 estimates and assumptions reflected in these consolidated financial
 statements include, but are not limited to, valuation of warrants,
 Series&amp;#xA0;1 nonconvertible preferred stock and stock-based
 awards; the useful lives of property and equipment; and the
 accounting for income taxes, including uncertain tax positions.
 Estimates are periodically reviewed in light of changes in
 circumstances, facts and experience. Actual results could differ
 from the Company&amp;#x2019;s estimates.&lt;/p&gt;

 In October and November 2010, the Company issued warrants to
 purchase up to a total of 1,999,989 shares of Series&amp;#xA0;1
 nonconvertible preferred stock, which expire on October&amp;#xA0;4,
 2017. As these warrants are free-standing financial instruments
 that may require the Company to transfer assets upon exercise,
 these warrants are classified as liabilities. The Company is
 required to remeasure the fair value of these preferred stock
 warrants at each reporting date, with any adjustments recorded
 within the change in fair value of warrant liability included in
 other income (expense) in the consolidated statement of operations.
 On February&amp;#xA0;5, 2014, 225,408 warrants were exercised resulting
 in the net issuance of 223,153 shares of Series&amp;#xA0;1
 nonconvertible preferred stock. As of March&amp;#xA0;31, 2015 and
 September&amp;#xA0;30, 2014, the total fair value of the
 Series&amp;#xA0;1&amp;#xA0;nonconvertible preferred stock was $185 and

 September&amp;#xA0;30, 2014, the total fair value of the Series 1
 nonconvertible preferred stock warrants was $1,442 and $1,584,

 Enanta Pharmaceuticals, Inc. (the &amp;#x201C;Company&amp;#x201D;),
 incorporated in Delaware in 1995, is a research and
 development-focused biotechnology company that uses its
 chemistry-driven approach and drug discovery capabilities to create
 small molecule drugs for the treatment of viral infections and
 liver diseases. The Company has programs to develop novel protease,
 NS5A, cyclophilin and nucleotide polymerase inhibitors targeted
 against the hepatitis C virus (&amp;#x201C;HCV&amp;#x201D;) and also recently
 announced a new focus area in non-alcoholic steatohepatitis
 (&amp;#x201C;NASH&amp;#x201D;). Additionally, the Company has programs to
 discover new chemical entities for the treatment of other
 diseases.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The Company is subject to risks common to companies in the
 biotechnology industry including, but not limited to, the
 uncertainties of research and development, competition from
 technological innovations of others, dependence on collaborative
 arrangements, protection of proprietary technology, dependence on
 key personnel, compliance with government regulations and the need
 for financial resources to fund research and development
 activities. Product candidates currently under development will
 require significant additional research and development efforts,
 including extensive preclinical and clinical testing and regulatory
 approval, prior to commercialization. These efforts require
 significant amounts of additional capital, adequate personnel
 infrastructure and extensive compliance reporting capabilities.&lt;/p&gt;
 &lt;p style="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;Unaudited Interim Financial Information&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The consolidated balance sheet at September&amp;#xA0;30, 2014 was
 derived from the audited financial statements, but does not include
 all disclosures required by accounting principles generally
 accepted in the United States of America (&amp;#x201C;GAAP&amp;#x201D;). The
 accompanying unaudited consolidated financial statements as of
 March&amp;#xA0;31, 2015 and for the three and six months ended
 March&amp;#xA0;31, 2015 and 2014 have been prepared by the Company,
 pursuant to the rules and regulations of the Securities and
 Exchange Commission (&amp;#x201C;SEC&amp;#x201D;) for interim financial
 statements. Certain information and note disclosures normally
 included in financial statements prepared in accordance with GAAP
 have been condensed or omitted pursuant to such rules and
 regulations. These financial statements should be read in
 conjunction with the Company&amp;#x2019;s audited financial statements
 and the notes thereto for the fiscal year ended September&amp;#xA0;30,
 2014 included in the Company&amp;#x2019;s Annual Report on Form 10-K for
 that fiscal year.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 In the opinion of management, all adjustments, consisting only of
 normal recurring adjustments necessary for a fair statement of the
 Company&amp;#x2019;s financial position as of March&amp;#xA0;31, 2015 and
 results of operations for the three and six months ended
 March&amp;#xA0;31, 2015 and 2014 and cash flows for the six months
 ended March&amp;#xA0;31, 2015 and 2014 have been made. The results of
 operations for the three and six months ended March&amp;#xA0;31, 2015
 are not necessarily indicative of the results of operations that
 may be expected for subsequent quarters or the year ending
 September&amp;#xA0;30, 2015.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"&gt;
 The accompanying consolidated financial statements have been
 prepared in conformity with GAAP. All dollar amounts in the
 consolidated financial statements and in the notes to the
 consolidated financial statements, except share and per share
 amounts, are in thousands unless otherwise indicated.&lt;/p&gt;

 For the three months ended March&amp;#xA0;31, 2015 and March&amp;#xA0;31,
 2014, the Company recorded an income tax provisions of $20,018 and
 $0, respectively, representing effective tax rates of 41.0% and
 0.0%, respectively. The income tax provision for the three months
 ended March&amp;#xA0;31, 2015 was attributable to the federal and state
 taxes provided on the earnings of the Company&amp;#x2019;s operations,
 all of which are domestic. During the three months ended
 March&amp;#xA0;31, 2015, the gross deferred tax assets decreased by
 $434 primarily as a result of the utilization of net operating
 losses due to income before income taxes generated during the
 period. No provision for income tax was recorded for the three
 months ended March&amp;#xA0;31, 2014, as the Company maintained a
 valuation allowance against its deferred tax assets. The valuation
 allowance was released during the three months ended June&amp;#xA0;30,
 2014.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 For the six months ended March&amp;#xA0;31, 2015 and March&amp;#xA0;31,
 2014, the Company recorded an income tax provision of $48,520 and
 $0, respectively. During the six months ended March&amp;#xA0;31, 2015,
 the gross deferred tax assets decreased by $10,002 primarily as a
 result of the utilization of net operating losses due to income
 before income taxes generated during the period. No provision for
 income tax was recorded for the six months ended March&amp;#xA0;31,
 2014, as the Company maintained a valuation allowance against its
 deferred tax assets.&lt;/p&gt;

 The Company files tax returns as prescribed by the tax laws of the
 jurisdictions in which it operates. In the normal course of
 business, the Company is subject to examination by federal and
 state jurisdictions, where applicable. There are currently no
 pending income tax examinations. The Company&amp;#x2019;s tax years are
 still open under statute from 2007 to the present. Earlier years
 may be examined to the extent that tax credit or net operating loss
 carryforwards are used in future periods.&lt;/p&gt;

 The Company had no unrecognized tax benefits as of March&amp;#xA0;31,
 2015 or September&amp;#xA0;30, 2014. Unrecognized tax benefits
 represent tax positions for which reserves have been established.
 The Company&amp;#x2019;s policy is to record interest and penalties
 related to uncertain tax positions as part of its income tax
 provision.&lt;/p&gt;

 The preparation of consolidated financial statements in conformity
 with GAAP requires management to make estimates and assumptions
 that affect the reported amounts of assets and liabilities, the
 disclosure of contingent assets and liabilities at the date of the
 consolidated financial statements, and the reported amounts of
 revenues and expenses during the reporting period. Significant
 estimates and assumptions reflected in these consolidated financial
 statements include, but are not limited to, valuation of warrants,
 Series&amp;#xA0;1 nonconvertible preferred stock and stock-based
 awards; the useful lives of property and equipment; and the
 accounting for income taxes, including uncertain tax positions.
 Estimates are periodically reviewed in light of changes in
 circumstances, facts and experience. Actual results could differ
 from the Company&amp;#x2019;s estimates.&lt;/p&gt;

 &lt;b&gt;Revenue Recognition&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 6pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The Company&amp;#x2019;s revenue has been generated primarily through
 collaborative research and license agreements. The terms of these
 agreements contain multiple deliverables, which may include
 (i)&amp;#xA0;licenses, (ii)&amp;#xA0;research and development activities,
 and (iii)&amp;#xA0;participation in joint research and development
 steering committees. The terms of these agreements may include
 nonrefundable upfront license fees, payments for research and
 development activities, payments based upon the achievement of
 certain milestones, and royalty payments based on product sales
 derived from the collaboration. In all instances, revenue is
 recognized only when the price is fixed or determinable, persuasive
 evidence of an arrangement exists, delivery has occurred or the
 services have been rendered, collectibility of the resulting
 receivable is reasonably assured, and the Company has fulfilled its
 performance obligations under the contract.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 For agreements entered into prior to October&amp;#xA0;1, 2011, the
 Company evaluated license agreements with multiple deliverables to
 determine if the deliverable elements could be recognized
 separately by considering (i)&amp;#xA0;if the delivered elements
 (typically the license) had standalone value to the customer,
 (ii)&amp;#xA0;if the fair value of any undelivered elements (typically
 the research and development services and the steering committee
 activities) could be determined based on vendor-specific objective
 evidence (&amp;#x201C;VSOE&amp;#x201D;) or vendor objective evidence
 (&amp;#x201C;VOE&amp;#x201D;), and (iii)&amp;#xA0;if the arrangement included a
 general right of return relative to the delivered item, the
 delivery or performance of the undelivered item was considered
 probable and substantially within the control of the Company. VSOE
 of fair value was based on the consistent price of a deliverable
 when the Company regularly sold it on a standalone
 basis.&amp;#xA0;Alternatively, VOE was based upon third-party objective
 evidence of fair value. If the delivered elements had value on a
 standalone basis and the fair value of the undelivered elements
 could be determined based on VSOE or VOE, revenues of such elements
 were then accounted for separately as delivered with arrangement
 consideration allocated to the delivered elements based on the
 residual value method. If either (i)&amp;#xA0;the delivered elements
 were considered to not have standalone value or (ii)&amp;#xA0;VSOE or
 VOE of fair value for any of the undelivered elements could not be
 determined, the arrangement was accounted for as a single unit of
 accounting and all payments received were recognized as revenue
 over the estimated period of performance of the entire
 arrangement.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 On October&amp;#xA0;1, 2011, the Company adopted Accounting Standards
 Update (&amp;#x201C;ASU&amp;#x201D;) No.&amp;#xA0;2009-13,&amp;#xA0;&lt;i&gt;Multiple-Deliverable
 Revenue Arrangements&lt;/i&gt;&amp;#xA0;(&amp;#x201C;ASU 2009-13&amp;#x201D;).
 This guidance, which applies to multiple-element arrangements
 entered into or materially modified on or after October&amp;#xA0;1,
 2011, amends the criteria for separating and allocating
 consideration in a multiple-element arrangement by modifying the
 fair value requirements for revenue recognition and eliminating the
 use of the residual value method. The selling prices of
 deliverables under the arrangement may be derived using third-party
 evidence (&amp;#x201C;TPE&amp;#x201D;) or a best estimate of selling price
 (&amp;#x201C;BESP&amp;#x201D;), if VSOE is not available. The objective of
 BESP is to determine the price at which the Company would transact
 a sale if the element within the license agreement was sold on a
 standalone basis. Establishing BESP involves management&amp;#x2019;s
 judgment and considers multiple factors, including market
 conditions and company-specific factors including those factors
 contemplated in negotiating the agreements as well as internally
 developed models that include assumptions related to market
 opportunity, discounted cash flows, estimated development costs,
 probability of success, and the time needed to commercialize a
 product candidate pursuant to the license. In validating the
 Company&amp;#x2019;s BESP, the Company considers whether changes in key
 assumptions used to determine the BESP will have a significant
 effect on the allocation of the arrangement consideration between
 the multiple deliverables. Deliverables under the arrangement are
 separate units of accounting if (i)&amp;#xA0;the delivered item has
 value to the customer on a standalone basis, and (ii)&amp;#xA0;if the
 arrangement includes a general right of return relative to the
 delivered item, delivery or performance of the undelivered item is
 considered probable and substantially within the control of the
 Company. The arrangement consideration that is fixed or
 determinable at the inception of the arrangement is allocated to
 the separate units of accounting based on their relative selling
 prices. The appropriate revenue recognition model is applied to
 each element, and revenue is accordingly recognized as each element
 is delivered. The Company may exercise significant judgment in
 determining whether a deliverable is a separate unit of accounting.
 The Company elected to adopt ASU 2009-13 prospectively as of
 October&amp;#xA0;1, 2011.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 In determining the separate units of accounting, the Company
 evaluates whether the license has standalone value to the
 collaborator based on consideration of the relevant facts and
 circumstances for each arrangement. Factors considered in this
 determination include the research and development capabilities of
 the collaborator and the availability of relevant research
 expertise in the marketplace. In addition, the Company considers
 whether or not (i)&amp;#xA0;the collaborator can use the license for
 its intended purpose without the receipt of the remaining
 deliverables, (ii)&amp;#xA0;the value of the license is dependent on
 the undelivered items, and (iii)&amp;#xA0;the collaborator or other
 vendors can provide the undelivered items.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Under a collaborative research and license agreement, a steering
 committee is typically responsible for overseeing the general
 working relationships, determining the protocols to be followed in
 the research and development performed, and evaluating the results
 from the continued development of the product in order to determine
 the clinical studies to be performed. The Company evaluates whether
 its participation in joint research and development steering
 committees is a substantive obligation or whether the services are
 considered inconsequential or perfunctory. The Company&amp;#x2019;s
 participation on a steering committee is considered
 &amp;#x201C;participatory&amp;#x201D; and therefore accounted for as a
 separate element when the collaborator requires the participation
 of the Company to ensure all elements of an arrangement are
 maximized. Steering committee services that are considered
 participatory are combined with other research services or
 performance obligations required under an arrangement, if any, in
 determining the level of effort required in an arrangement and the
 period over which the Company expects to complete its aggregate
 performance obligations. Alternatively, the Company&amp;#x2019;s
 participation on a steering committee is considered
 &amp;#x201C;protective&amp;#x201D; and therefore not accounted for as a
 separate element in a case where the Company can exercise or
 control when to be involved at its own discretion. Factors the
 Company considers in determining if its participation in a joint
 steering committee is participating or protective include:
 (i)&amp;#xA0;which party negotiated or requested the steering
 committee, (ii)&amp;#xA0;how frequently the steering committee meets,
 (iii)&amp;#xA0;whether or not there are any penalties or other recourse
 if the Company does not attend the steering committee meetings,
 (iv)&amp;#xA0;which party has decision making authority on the steering
 committee, and (v)&amp;#xA0;whether or not the collaborator has the
 requisite experience and expertise associated with the research and
 development of the licensed intellectual property.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 For all periods presented, whenever the Company determines that an
 element is delivered over a period of time, revenue is recognized
 using either a proportional performance model or a straight-line
 model over the period of performance, which is typically the
 research and development term. Full-time equivalents
 (&amp;#x201C;FTEs&amp;#x201D;) are typically used as the measure of
 performance. At each reporting period, the Company reassesses its
 cumulative measure of performance and makes appropriate
 adjustments, if necessary. The Company recognizes revenue using the
 proportional performance model whenever the Company can make
 reasonably reliable estimates of the level of effort required to
 complete its performance obligations under an arrangement. Revenue
 recognized under the proportional performance model at each
 reporting period is determined by multiplying the total expected
 payments under the contract (excluding royalties and payments
 contingent upon achievement of milestones) by the ratio of the
 level of effort incurred to date to the estimated total level of
 effort required to complete the performance obligations under the
 arrangement. Revenue is limited to the lesser of the cumulative
 amount of payments received or the cumulative amount of revenue
 earned, as determined using the proportional performance model as
 of each reporting period. Alternatively, if the Company cannot make
 reasonably reliable estimates of the level of effort required to
 complete its performance obligations under an arrangement, then
 revenue under the arrangement is recognized on a straight-line
 basis over the period expected to complete the Company&amp;#x2019;s
 performance obligations. If and when a contingent milestone payment
 is earned, the additional consideration to be received is allocated
 to the separate units of accounting in the arrangement based on
 their relative selling prices at the inception of the arrangement.
 Revenue is limited to the lesser of the cumulative amount of
 payments received or the cumulative amount of revenue earned, as
 determined on a straight-line basis as of the period end date. If
 the Company cannot reasonably estimate when its performance
 obligation period ends, then revenue is deferred until the Company
 can reasonably estimate when the performance obligation period
 ends.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Royalty revenue is recognized based on contractual terms when
 reported sales are reliably measurable and collectibility is
 reasonably assured, provided that there are no performance
 obligations then remaining.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 During the three and six months ended March&amp;#xA0;31, 2015 and 2014,
 the Company also generated revenue from a government contract,
 under which the Company is reimbursed for certain allowable costs
 for the funded project. Revenue from the government contract is
 recognized when the related service is performed. The related costs
 incurred by the Company under the government contract are included
 in research and development expenses in the statements of
 operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 Amounts received prior to satisfying all revenue recognition
 criteria are recorded as deferred revenue in the accompanying
 consolidated balance sheets. Amounts not expected to be recognized
 as revenue within the next twelve months of the consolidated
 balance sheet date are classified as long-term deferred
 revenue.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 In the event that a collaborative research and license agreement is
 terminated and the Company then has no further performance
 obligations, the Company recognizes as revenue any amounts that had
 not previously been recorded as revenue but were classified as
 deferred revenue at the date of such termination.&lt;/p&gt;

 In May, 2014, the Financial Accounting Standards Board (the
 &amp;#x201C;FASB&amp;#x201D;) issued ASU No.&amp;#xA0;2014-09,&amp;#xA0;&lt;i&gt;Revenue from Contracts with
 Customers&lt;/i&gt;&amp;#xA0;(Topic 606), which supersedes
 all existing revenue recognition requirements, including most
 industry-specific guidance. The new standard requires a company to
 recognize revenue when it transfers goods or services to customers
 in an amount that reflects the consideration that the company
 expects to receive for those goods or services. The new standard
 will be effective for the Company on October&amp;#xA0;1, 2017; however
 there is a pending proposal to delay the effective period by one
 year. The Company is currently evaluating the potential impact that
 Topic 606 may have on its financial position and results of

 The Company&amp;#x2019;s 2012 Equity Incentive Plan (the
 &amp;#x201C;2012&amp;#xA0;Plan&amp;#x201D;) permits the Company to sell or issue
 common stock or restricted common stock or to grant incentive stock
 options or nonqualified stock options for the purchase of common
 stock, restricted stock units, stock appreciation rights or other
 cash incentive awards, to employees, members of the board of
 directors and consultants of the Company. The number of shares of
 common stock that may be issued under the 2012 Plan is subject to
 increase by the number of shares forfeited under any options
 terminated and not exercised under the 2012 Plan or the previous
 plan, known as the 1995 Equity Incentive Plan, as well as by a
 number of additional shares automatically on the first day of each
 fiscal year equal to the lowest amount among the following:
 (i)&amp;#xA0;3% of the Company&amp;#x2019;s outstanding shares of common
 stock as of that date, (ii)&amp;#xA0;2,088,167 shares of common stock,
 or (iii)&amp;#xA0;a lower amount determined by the board of directors.
 On October&amp;#xA0;1, 2014, the number of shares of common stock that
 may be issued under the 2012 Plan was increased by 557,863. As of
 March&amp;#xA0;31, 2015, 529,176 shares remained available for future
 grant.&lt;/p&gt;

 The fair value of each stock option grant is estimated on the date
 of grant using the Black-Scholes option-pricing model. To date the
 Company lacks sufficient company-specific historical volatility
 information. Therefore, it estimates its expected stock volatility
 based on the historical volatility of a selected group of publicly
 traded peer companies and expects to continue to do so until such
 time as it has adequate historical data regarding the volatility of
 its own traded stock price. The expected term of the
 Company&amp;#x2019;s stock options has been determined utilizing the
 &amp;#x201C;simplified&amp;#x201D; method for awards that qualify as
 &amp;#x201C;plain-vanilla&amp;#x201D; options. The risk-free interest rate is
 determined by reference to the U.S.&amp;#xA0;Treasury yield curve in
 effect at the time of grant of the award for time periods
 approximately equal to the expected term of the award. Expected
 dividend yield is based on the fact that the Company has never paid
 cash dividends and does not expect to pay any cash dividends in the
 foreseeable future. The relevant data used to determine the value
 of the stock option grants is as follows, presented on a weighted
 average basis:&lt;/p&gt;

 The Company recognizes compensation expense for only the portion of
 awards that are expected to vest. In developing a forfeiture rate
 estimate, the Company has considered its historical experience to
 estimate pre-vesting forfeitures for service-based awards. The
 impact of a forfeiture rate adjustment will be recognized in full
 in the period of adjustment, and if the actual forfeiture rate is
 materially different from the Company&amp;#x2019;s estimate, the Company
 may be required to record adjustments to stock-based compensation
 expense in future periods.&lt;/p&gt;

 As required by the 2012 Plan, the exercise price for awards granted
 is not to be less than the fair value of common shares as estimated
 by the Company as of the date of grant. For the periods prior to
 the March 2013 IPO, the Company valued its common stock by taking
 into consideration its most recently available valuation of common
 shares performed by management and the board of directors as well
 as additional factors which may have changed since the date of the
 most recent contemporaneous valuation through the date of grant.
 For the periods after the IPO, the Company based fair value of its
 common stock on the quoted market price.&lt;/p&gt;

 In March&amp;#xA0;2013, the Company granted certain executives a total
 of 167,052 options that vest upon the achievement of certain
 performance-based targets. The grant date fair value of these
 options was $2,479. During the three and six months ended
 March&amp;#xA0;31, 2015, the Company recorded no compensation expense
 related to these options as none of the remaining performance-based
 targets became probable of being achieved during these periods.
 During the three months ended March&amp;#xA0;31, 2014, one
 performance-based target was achieved and the Company recorded
 compensation expense of $206 related to that target.&lt;/p&gt;

 &lt;b&gt;Market and Performance-based Stock Awards&lt;/b&gt;&lt;/p&gt;

 In February 2015, the Company awarded certain executive officers a
 total of 41,800 share units consisting of 20,900 performance share
 units, or PSUs, and 20,900 relative total shareholder return units,
 or rTSRUs. The number of units represents the target number of
 shares of common stock that may be earned; however, the actual
 number of shares that may be earned ranges from 0% to 200% of the
 target number.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The PSUs will vest and result in issuance, or settlement, of common
 shares, based upon continued employment and achievement of
 specified research and development milestones on or before
 December&amp;#xA0;16, 2016. The aggregate grant date fair value of the
 20,900 PSUs ranges between $0 and $1,501. During the three months
 ended March&amp;#xA0;31, 2015, the Company recorded no compensation
 expense related to the PSU awards as none of the performance-based
 targets was probable of being achieved during this period.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;
 The rTSRUs will vest and result in the issuance of common stock
 based on continuing employment and the relative ranking of the
 total shareholder return, or TSR, of the Company&amp;#x2019;s common
 stock in relation to the TSR of the component companies in the
 NASDAQ Biotech Index over a two-year period based on a comparison
 of average closing stock prices in December 2014 and December 2016.
 The number of market-based rTSRUs awarded represents the target
 number of shares of common stock that may be earned; however, the
 actual number of shares that may be earned ranges from 0% to 200%
 of the target number.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 1px &apos;Times New Roman&apos;; WIDOWS: 1; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px"&gt;

 The Company used a Monte Carlo simulation model to estimate that
 the grant-date fair value of the rTSRUs was $554. The table below
 sets forth the assumptions used to value the awards and the
 estimated grant-date fair value:&lt;/p&gt;

 instruments was based on significant inputs not observable in the
 market, which represented a Level&amp;#xA0;3 measurement within the
 fair value hierarchy. The Company utilized a probability-weighted
 valuation model which takes into consideration various outcomes
 that may require the Company to transfer assets upon exercise. The
 fair value of warrants to purchase our Series 1 nonconvertible
 preferred stock was $1,442 and $1,584, at March&amp;#xA0;31, 2015 and
 September&amp;#xA0;30, 2014, respectively. The fair value of
 Series&amp;#xA0;1 nonconvertible preferred stock was $185 and $202 as
 of March&amp;#xA0;31, 2015 and September&amp;#xA0;30, 2014, respectively.
 Changes in the fair value of the warrant liability and
 Series&amp;#xA0;1 nonconvertible preferred stock are recognized in the
 consolidated statements of operations.&lt;/p&gt;

 In May, 2014, the Financial Accounting Standards Board (the
 &amp;#x201C;FASB&amp;#x201D;) issued ASU No.&amp;#xA0;2014-09,&amp;#xA0;&lt;i&gt;Revenue from Contracts with
 Customers&lt;/i&gt;&amp;#xA0;(Topic 606), which supersedes
 all existing revenue recognition requirements, including most
 industry-specific guidance. The new standard requires a company to
 recognize revenue when it transfers goods or services to customers
 in an amount that reflects the consideration that the company
 expects to receive for those goods or services. The new standard
 will be effective for the Company on October&amp;#xA0;1, 2017; however
 there is a pending proposal to delay the effective period by one
 year. The Company is currently evaluating the potential impact that
 Topic 606 may have on its financial position and results of
 operations.&lt;/p&gt;
