 Exhibit 10.23 

CHANGE OF CONTROL AGREEMENT 

This Change of Control Agreement (the “Agreement”), dated as of
            , 2014 (the “Effective Date”), is made by and between Avanir Pharmaceuticals, Inc., a Delaware corporation having its principal offices at 30 Enterprise, Suite
400, Aliso Viejo, California (the “Company”) and <Name> (“Employee”). 
 RECITALS 

A. It is expected that other entities or individuals may, from time to time, consider the possibility of acquiring the Company in a
transaction that will result in a Change of Control (defined below), with or without the approval of the Company’s Board of Directors. The Board of Directors recognizes that such consideration may cause Employee to consider alternative
employment opportunities. Accordingly, the Board of Directors has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication and objectivity of Employee,
notwithstanding the possibility, threat or occurrence of a Change of Control. 
 B. The Company’s Board of Directors believes it is in
the best interests of the Company and its shareholders to enter into this Agreement to provide incentives to Employee to continue in the service of the Company in the event of a Change of Control. 

C. The Board of Directors further believes that it is necessary to provide Employee with certain benefits upon termination of Employee’s
employment in connection with a Change of Control, which benefits are intended to provide Employee with financial security and provide sufficient income and encouragement to Employee to remain employed by the Company, notwithstanding the possibility
of a Change of Control. 
 NOW, THEREFORE, in consideration of the mutual promises, covenants and agreements contained herein, and in
consideration of the continuing employment of Employee by the Company, the parties hereto agree as follows: 
 1. Definitions. 

1.1 “Awards” means Employee’s outstanding stock options, restricted stock awards, restricted stock units, stock
appreciation rights and other equity-based awards granted under the Company Equity Plans, in each case that remain outstanding immediately following a Change of Control. 

1.2 “Base Salary” means Employee’s gross monthly salary on the date of calculation, which, for the avoidance of doubt,
excludes any bonus or other incentive compensation. 
 1.3 “Cause” shall, if applicable, have the meaning set forth in the
definitive written employment agreement between Employee and the Company (the “Employment Agreement”); provided, however, that if there is no Employment Agreement, or if the Employment Agreement does not define what shall constitute a
termination for “cause” (or a substantially similar term), then “Cause” for purposes of this Agreement shall mean: (i) Employee’s material breach of this Agreement or any confidentiality agreement between the Company
and Employee; (ii)

 
Employee’s failure or refusal to comply with the Company’s Employee Manual, the Company’s Code of Business Conduct and Ethics, or other policies or procedures established by the
Company (iii) Employee’s appropriation (or attempted appropriation) of a material business opportunity of the Company, including attempting to secure or securing any personal profit in connection with any transaction entered into on behalf
of the Company; (iv) Employee’s misappropriation (or attempted misappropriation) of any of the Company’s funds or material property; (v) Employee’s conviction of, or the entering of a guilty plea or plea of no contest with
respect to a felony, the equivalent thereof, or any other crime with respect to which imprisonment is a possible punishment; or (vi) Employee’s willful misconduct or incompetence.

or group deemed to be a person under Section 14(d)(2) of the Securities Exchange Act of 1934 (the “Exchange Act”) is or becomes the “Beneficial Owner” (as defined in Rule 13d-3 under the Exchange Act), directly or
indirectly, of securities of the Company representing 50% or more of the combined voting power of the Company’s then outstanding securities entitled to vote in the election of directors of the Company; or 

(b) if those individuals who constituted the Board at the Effective Date (together with any directors elected or nominated by a majority of
such members) cease to constitute a majority of the Board as a result of, or in connection with, a proxy solicitation made by a third party pursuant to Regulation 14A under the Securities Exchange Act of 1934; or 

(c) there occurs a reorganization, merger, consolidation or other corporate transaction involving the Company (“Transaction”),
in each case, with respect to which the stockholders of the Company immediately prior to such Transaction do not, immediately after the Transaction, own, directly or indirectly, more than 50% of the combined voting power of the Company’s then
outstanding securities entitled to vote in the election of directors of the Company or of the securities of any other corporation resulting from such Transaction; or 

(d) all or substantially all of the assets of the Company are sold, liquidated or distributed to an unrelated third party, other than in
connection with a bankruptcy, insolvency or other similar proceeding, or an assignment for the benefit of creditors. 
 1.6 A
“Change of Control Termination” shall have occurred if Employee’s employment by the Company, or any of its subsidiaries or affiliates, is terminated without Cause or Employee resigns in a Resignation for Good Reason, in either
case subsequent to the signing of an agreement, the consummation of which would result in a Change of Control, or within 12 months following the effective date of a Change of Control. 

1.7 A “Death or Disability Change of Control Termination” shall have occurred if Employee’s employment by the Company,
or any of its subsidiaries or affiliates, is terminated by reason of Employee’s Disability or death, in either case subsequent to the signing of an agreement, the consummation of which would result in a Change of Control, or within 12 months
following the effective date of a Change of Control.

gainful activity because of a medically determinable physical or mental impairment that can be expected to result in death or to last for a continuous period of at least 12 months; or (b) Employee has been receiving income replacement benefits

1.13 “Resignation for Good Reason” shall, if applicable, have the meaning set forth in the Employment Agreement; provided,
however, that if there is no Employment Agreement, or if the Employment Agreement does not define what shall constitute a termination for “good reason” (or a substantially similar term), then “Resignation for Good Reason” for
purposes of this Agreement means a resignation based on any of the following events occurring in each case without Employee’s consent, each of which shall constitute “Good Reason,” subject to the notice and cure provisions set forth
below: 
 (a) a material diminution in Employee’s authority, duties, reporting relationship, or responsibilities; 

(b) a material diminution in Employee’s Base Salary; 

(c) a material change in geographic location at which the Employee must perform the services; or

existence of the event constituting Good Reason, (ii) Employee may not terminate his or her employment unless the Company fails to remedy the event constituting Good Reason within 30 days after such notice has been deemed given

pursuant to this Agreement, and (iii) Employee must terminate employment with the Company no later than 30 days after the end of the 30-day period in which the Company fails to remedy the
event constituting Good Reason.

Base Salary, plus an amount equal to the greater of (A) the aggregate annual cash bonus payment(s) received by Employee in the Company’s preceding fiscal year or (B) Employee’s target annual cash bonus amount, such payments to be
paid in accordance with the terms in Section 2.1(b) below. Notwithstanding the foregoing, if the tenure of Employee’s employment with the Company at the time of termination is less than one year, then the bonus amount calculated under this
Section 1.11 shall be pro rated for the partial year of service. 
 1.15 “Severance Period” means the 12-month period
following a Change of Control Termination. 
 2. Change of Control Termination. 

2.1 Payment upon Change of Control Termination. Subject to Sections 2.2 and 2.3, in the event of a Change of Control Termination: 

(a) The Company shall promptly pay Employee all accrued but unpaid Base Salary and all accrued but unused vacation time, each through the date
of termination, plus any annual cash bonus payment earned by Employee for the fiscal year preceding the year of termination to the extent unpaid at the time of termination; and 

(b) The Company shall pay Employee the Severance Payment after the date of termination, which Severance Payment shall be payable in one
lump-sum payment on the first payroll date that is 30 days after the date of such termination. ; and 
 (c) Employee may elect to continue
insurance coverage as afforded to Employee according to COBRA, and, if such election is made, Employee shall be entitled to reimbursement of COBRA coverage during the Severance Period. Nothing in this Agreement will extend Employee’s COBRA
period beyond the period allowed under COBRA, nor is Company assuming any responsibility for Employee’s election to continue coverage. Notwithstanding the foregoing, the foregoing benefit can be provided, at the Company’s sole discretion,
in the form of a lump sum taxable severance payment in lieu of the COBRA subsidy if the COBRA subsidy is found to be discriminatory pursuant to applicable law; and 

(d) As of the date of termination, the vesting of all Awards shall accelerate in full and all rights of repurchase of Award shares shall
immediately lapse with any performance-based vesting criteria deemed achieved at the target level of performance. 
 (e) In the event of a
Death or Disability Change of Control Termination, subject to Section 2.2 (which shall apply pursuant to this Section 2.1(e) only in the event of a termination due to Employee’s Disability) and Section 2.3, Employee shall receive
the compensation stated in Sections 2.1(a) through (d) pursuant to the same terms and conditions stated therein; provided, however, that the Severance Payment shall be pro rated by a fraction, 

  
 4 

 
the numerator of which is the number of days elapsed from the date of the Change of Control (or the signing of an agreement the consummation of which will result in a Change of Control, if such
death or termination occurs prior to the actual Change of Control) through the date of death or termination, as the case may be, and the denominator of which is 365. 

2.2 Employee Release. In consideration for the benefits set forth above in Sections 2.1(b), 2.1(c), 2.1(d) and, if applicable, 2.1(e),
following either a Change of Control Termination or a Death or Disability Change of Control Termination due to Disability, as applicable, Employee shall execute and deliver the Release no later than 21 days after termination of employment. The
Company shall have no obligation to pay or grant the benefits set forth in Sections 2.1(b), 2.1(c), 2.1(d) or 2.1(e) unless the Release becomes effective and irrevocable within 30 days after termination of employment. 

2.3 Other Benefits. In the event that the Employment Agreement provides for specific benefits upon a Change of Control and/or a Change
of Control Termination that are materially more favorable to Employee than like benefits set forth herein, then Employee shall be entitled to those benefits set forth in the Employment Agreement in lieu of the lesser like benefits set forth herein.
For the avoidance of doubt, in no event shall Employee be entitled to severance compensation upon Change of Control Termination under both this Agreement and the Employment Agreement. 

3. Excise Tax Cutback. 
 3.1 Anything in
this Agreement to the contrary notwithstanding, in the event that any compensation, payment or distribution by the Company to or for the benefit of Employee, whether paid or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise (collectively, the “Payments”), (i) constitute “parachute payments” within the meaning of Section 280G of the Code, and (ii) but for this Section 3 would be subject to the excise
tax imposed by Section 4999 of the Code, or any comparable successor provisions (the “Excise Tax”), then Employee’s Payments hereunder shall be either (1) provided to Employee in full, or (2) provided to Employee
as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, when taking into account applicable federal, state, local and foreign income and employment taxes, the
Excise Tax, and any other applicable taxes, results in the receipt by Employee, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under the Excise Tax. 

3.2 In the event the Payments are to be reduced pursuant to Section 3.1, the Payments shall be reduced in the following order:
(1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits. To the extent any payment
is to be made over time (e.g., in installments, etc.), then the payments shall be reduced in reverse chronological order. The determination any reduction pursuant to this Section 3 shall be made by a nationally recognized accounting firm
selected and paid for by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and the Employee within 15 business days of the date of termination of service, if applicable, or
at such earlier time as is reasonably requested by the Company or the Employee. For purposes of this 

  
 5 

 
determination, the Accounting Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application
of the Code, and other applicable legal authority. Any determination by the Accounting Firm shall be binding upon the Company and Employee. 
 4. Dispute
Resolution Procedures. Any dispute or claim arising out of this Agreement shall be subject to final and binding arbitration. The arbitration will be conducted by one arbitrator who is a member of the American Arbitration Association (AAA) or of
the Judicial Arbitration and Mediation Services (JAMS). The arbitration shall be held in Orange County, California. The arbitrator shall have all authority to determine the arbitrability of any claim and enter a final and binding judgment at the
conclusion of any proceedings in respect of the arbitration. Notwithstanding any rule of AAA or JAMS to the contrary, the provisions of Title 9 of Part 3 of the CCC including Section 1283.05, and successor statutes, permitting expanded
discovery proceedings shall be applicable to all disputes that are arbitrated under this paragraph. The arbitrator shall have all power and authority to enter orders relating to such discovery as are allowed under the CCC. The party prevailing in
the resolution of any such claim will be entitled, in addition to such other relief as may be granted, to an award of all fees and costs incurred in pursuit of the claim (including reasonable attorneys’ fees) without regard to any statute,
schedule, or rule of court purported to restrict such award. 
 5. At-Will Employment. Notwithstanding anything to the contrary herein, Employee
reaffirms that Employee’s employment relationship with the Company is at-will, terminable at any time and for any reason by either the Company or Employee. While certain paragraphs of this Agreement describe events that could occur at a
particular time in the future, nothing in this Agreement may be construed as a guarantee of employment of any length. 
 6. General Provisions. 

6.1 Governing Law. This Agreement will be governed by and construed in accordance with the laws of the State of California, without
regard to conflict-of-law principles. 
 6.2 Successors and Assigns. The provisions of this Agreement shall inure to the benefit of,
and be binding upon, the Company and its successors and assigns. Employee may not assign, pledge or encumber her interest in this Agreement or any part thereof, provided, however, that the provisions of this Agreement shall inure to the benefit of,
and be binding upon Employee’s estate. 
 6.3 No Waiver of Breach. If either party should waive any breach of any provisions of
this Agreement, he or it shall not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement. The rights granted the parties are cumulative, and the election of one will not constitute a
waiver of such party’s right to assert all other legal and equitable remedies available under the circumstances. 
 6.4
Severability. The provisions of this Agreement are severable, and if any provision will be held to be invalid or otherwise unenforceable, in whole or in part, the remainder of the provisions, or enforceable parts of this Agreement, will not
be affected. 

  
 6 

 6.5 Entire Agreement; Amendment. This Agreement, including Exhibit A, constitutes the
entire agreement of the parties with respect to the subject matter of this Agreement, and supersedes all prior and contemporaneous negotiations, agreements and understandings between the parties, oral or written, except those provisions of the
Employment Agreement expressly referred to herein. This Agreement may be amended or supplemented only by writing signed by both of the parties hereto. 

6.6 Modification; Waivers. No modification, termination or attempted waiver of this Agreement will be valid unless in writing, signed
by the party against whom such modification, termination or waiver is sought to be enforced. 
 6.7 Duplicate Counterparts. This
Agreement may be executed in duplicate counterparts; each of, which shall be deemed an original; provided, however, such counterparts shall together constitute only one instrument. 

6.8 Interpretation. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement. As used in this Agreement, words of the masculine gender shall mean and include corresponding neuter words or words of the feminine gender. 

6.9 No Mitigation. No payment to which Employee is entitled pursuant to Section 2.1 hereof shall be reduced by reason of
compensation or other income received by her for services rendered after termination of her employment with the Company. 
 6.10
Withholding of Taxes. The Company shall withhold appropriate federal, state, local (and foreign, if applicable) income and employment taxes from any payments hereunder. 

6.11 Drafting Ambiguities; Representation by Counsel. Each party to this Agreement and its counsel have reviewed and revised this
Agreement and the Release. The rule of construction that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement, the Release or any of the amendments to this Agreement. 

6.12 Prior Agreement. This Agreement amends and restates that certain Change of Control Agreement, dated <Date>, by and between
the Company and Employee. 
 6.13 Section 409A Compliance. 

(a) This Agreement is intended to comply with the requirements of Section 409A of the Code and the regulations and guidance promulgated
thereunder (“Section 409A”) or an exemption from Section 409A. The Company shall undertake to administer, interpret, and construe this Agreement in a manner that does not result in the imposition on Employee of any additional
tax, penalty, or interest under Section 409A. Each payment under this Agreement shall be treated as a separate payment for purposes of Section 409A. 

(b) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment
of any amounts or benefits upon or following a termination of employment unless such termination is also a 

  
 7 

 
“separation from service” within the meaning of Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination
of employment” or like terms shall mean “separation from service.” 
 (c) Notwithstanding anything herein to the contrary, in
the event that Employee is a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then with regard to any payment or the provision of any benefit (whether under this Agreement or otherwise)
that is considered deferred compensation under Section 409A payable on account of a “separation from service,” and that is not exempt from Section 409A as involuntary separation pay or a short-term deferral (or otherwise), to the
extent necessary to avoid the imposition of excise taxes under Section 409A, such payment or benefit shall be made or provided at the date which is the earlier of (i) the expiration of the six (6)-month period measured from the date of
such “separation from service” of Employee or (B) the date of Employee’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this
Section 6.13(c) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to Employee in a lump sum without interest, and any remaining payments and benefits due
under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. 
 (d) With regard to
any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A, all such payments shall be made on or before the last day of calendar year following the calendar year in which
the expense occurred.

forth above.

equal to 65% of the Base Salary. This annual bonus will be payable no later than the end of the first quarter of each fiscal year based on performance in the prior year. The actual bonus may be higher or lower than the target amount, depending on
your satisfaction of performance criteria established by the Compensation Committee of the Board and the Company’s overall performance. 

Equity Awards. The Compensation Committee will award you with equity compensation on terms to be determined by the Compensation
Committee, in its sole discretion. The Compensation Committee ordinarily assesses performance and makes annual equity compensation grants following the end of each fiscal year (i.e., in the first quarter of the following fiscal year). The
specific terms of such annual awards will be determined by the Compensation Committee. 
 BENEFITS AND EXPENSES 

As an AVANIR employee and member of senior management you will be eligible for the employee benefits relating to health insurance, life
insurance, disability insurance, etc., provided to other members of the Company’s senior management. In addition, all travel and other reasonable business expenses incurred by you in the performance of your duties will be reimbursed to you, in
accordance with the Company’s expense reimbursement policy. 
 SEVERANCE COMPENSATION 

As a member of AVANIR’s senior management team, you will remain eligible to receive those change of control severance benefits to which
you are currently entitled under the Company’s standard form of Change of Control Agreement, as amended from time to time. 
 In
addition, if the Company terminates your employment without Cause or you Resign for Good Reason (each as defined in the Change of Control Agreement) other than under circumstances that would constitute a “Change of Control Termination as
defined in the Change of Control Agreement, then, subject to your entering into the Company’s standard form of release of claims in favor of the Company and such release of claims becoming effective and irrevocable within thirty days following
your termination date, you will be entitled to severance pay equal to 24 months of Base Salary, plus an amount equal to two times the greater of (A) the aggregate annual cash bonus payment(s) received by Employee in the Company’s preceding
fiscal year or (B) Employee’s target annual cash bonus amount, with such severance benefits to be paid in one lump sum on the first payroll date that is thirty 

 
days following the date of termination. Additionally, in the event of such a termination of your employment without Cause or a resignation for Good Reason, the vesting of all of your unvested
equity-based compensation awards will be accelerated in full so as to vest as of the date of termination (with any performance-based vesting conditions deemed satisfied at the target level of performance), and you will have 90 days to exercise
all of your stock options that have vested as of the date of termination. 
 If you elect to continue insurance coverage as afforded according to COBRA,
and, if such election is made, you will be entitled to reimbursement of COBRA coverage for 24 months following the end of the existing coverage as an active employee. Nothing in this Agreement will extend the COBRA period beyond the period allowed
under COBRA, nor is the Company assuming any responsibility for your election to continue coverage. Notwithstanding the foregoing, the foregoing benefit can be provided, at the Company’s sole discretion, in the form of a lump sum taxable
severance payment in lieu of the COBRA subsidy if the COBRA subsidy is found to be discriminatory pursuant to applicable law. 
 Anything in this Agreement
to the contrary notwithstanding, if at the time of your separation from service, you are determined by the Company to be a ‘specified employee’ within the meaning of Section 409A(a)(2)(B)(i) of the Internal Revenue Code of 1986, as
amended (the ‘Code’), and if any payment that you become entitled to under this Agreement would be considered deferred compensation subject to interest and additional tax imposed pursuant to Section 409A(a) of the Code as a result of
the application of Section 409A(a)(2)(B)(i) of the Code, then no such payment shall be payable prior to the date that is the earlier of (1) six months and one day after your separation from service, or (2) your death. This letter is
intended to comply with the requirements of Section 409A of the Code and shall be interpreted in a manner consistent with that intent. Each payment made hereunder will be treated as a “separate payment” within the meaning of
Section 409A of the Code. 
 OTHER ITEMS 

Employment with the Company is considered “at will”, meaning it is for an unspecified period of time and that the employment
relationship may be terminated by yourself or by the Company at any time, with or without cause. Nothing in the Change of Control Agreement will modify this at will employment relationship. 

You will be required to devote your full time, attention, energy and skills to the Company during the period you are employed under this
Agreement. During your employment, you may not, directly or indirectly, either as an employee, employer, consultant, corporate officer or director, investor, or in any other capacity, engage or participate in any business that is in competition with
the business of the Company, unless such participation or interest is fully disclosed to the Company and approved by the Board. 
 This
letter, the Change of Control Agreement and the Inventions Agreement previously executed by you constitute the entire agreement between you and the Company with respect to the terms of your employment and, by signing below, will supersede all prior
and contemporaneous negotiations, agreements and understandings between you and the Company, whether oral or written (including your prior employment agreement, but excluding any agreements governing outstanding equity awards). Any amendments to
this agreement shall be in writing and signed by both parties. 
 We look forward to your continued contributions to Avanir.
