 Exhibit 10.14 

AVALANCHE BIOTECHNOLOGIES, INC. 

CHANGE IN CONTROL AND SEVERANCE AGREEMENT 

This Change in Control and Severance Agreement (the “Agreement”) is made and entered into by and between
[            ] (“Executive”) and Avalanche Biotechnologies, Inc. (the “Company”), effective as of the latest date set forth by the signatures of the parties hereto below
(the “Effective Date”). 
 R E C I T A L S 

A. It is expected that the Company from time to time will consider the possibility of an acquisition by another company or other change in
control. The Board of Directors of the Company (the “Board”) recognizes that such consideration as well as the possibility of an involuntary termination or reduction in responsibility can be a distraction to Executive and can cause
Executive to consider alternative employment opportunities. The Board has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication and objectivity of Executive,
notwithstanding the possibility, threat or occurrence of such an event. 
 B. The Board believes that it is in the best interests of the
Company and its stockholders to provide Executive with an incentive to continue Executive’s employment and to motivate Executive to maximize the value of the Company upon a Change in Control (as defined below) for the benefit of its
stockholders. 
 C. The Board believes that it is imperative to provide Executive with severance benefits upon certain terminations of
Executive’s service to the Company that enhance Executive’s financial security and provide incentive and encouragement to Executive to remain with the Company notwithstanding the possibility of such an event. 

D. Certain capitalized terms used in this Agreement are defined in Section 7 below. 

The parties hereto agree as follows: 

1. Term of Agreement. This Agreement shall become effective as of the Effective Date and terminate upon the date that all obligations of
the parties hereto with respect to this Agreement have been satisfied. 
 2. At-Will Employment. The Company and Executive
acknowledge that Executive’s employment is and shall continue to be “at-will,” as defined under applicable law. If Executive’s employment terminates for any reason, Executive shall not be entitled to any payments, benefits,
damages, awards or compensation other than as provided by this Agreement. 







 3. Covered Termination Other Than During a Change in Control Period. If Executive
experiences a Covered Termination other than during a Change in Control Period, and if Executive delivers to the Company a general release of all claims against the Company and its affiliates that becomes effective and irrevocable within sixty
(60) days, or such shorter period of time specified by the Company, following such Covered Termination (a “Release of Claims”), then in addition to any accrued but unpaid salary, bonus, vacation and expense reimbursement payable in
accordance with applicable law, the Company shall provide Executive with the following: 
 (a) Severance. Executive shall be entitled
to receive an amount equal to nine (9) months of Executive’s Base Salary, payable in substantially equal installments in accordance with the Company’s normal payroll policies, less applicable withholdings; provided, however,
that no payments under this Section 3(a) shall be made prior to the first payroll date occurring on or after the sixtieth (60th) day following the date of the Covered Termination (such payroll date, the “First Payroll
Date”), and any amounts otherwise payable prior to the First Payroll Date shall be paid on the First Payroll Date without interest thereon. 

(b) Continued Healthcare. If Executive elects to receive continued healthcare coverage pursuant to the provisions of the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall directly pay, or reimburse Executive for, the premium for Executive and Executive’s covered dependents through the earlier of (i) the nine (9)-
month anniversary of the date of Executive’s termination of employment and (ii) the date Executive and Executive’s covered dependents, if any, become eligible for healthcare coverage under another employer’s plan(s).
Notwithstanding the foregoing, (i) if any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the period of continuation coverage to be, exempt from the application of Section 409A of the Code
under Treasury Regulation Section 1.409A-1(a)(5), or (ii) the Company is otherwise unable to continue to cover Executive under its group health plans without penalty under applicable law (including without limitation, Section 2716 of
the Public Health Service Act), then, in either case, an amount equal to each remaining Company subsidy shall thereafter be paid to Executive in substantially equal monthly installments. After the Company ceases to pay premiums pursuant to this
Section 3(b), Executive may, if eligible, elect to continue healthcare coverage at Executive’s expense in accordance the provisions of COBRA. 

4. Covered Termination During a Change in Control Period. If Executive experiences a Covered Termination during a Change in Control
Period, and if Executive delivers to the Company a Release of Claims that becomes effective and irrevocable within sixty (60) days, or such shorter period of time specified by the Company, following such Covered Termination, then in addition to
any accrued but unpaid salary, bonus, vacation and expense reimbursement payable in accordance with applicable law, the Company shall provide Executive with the following: 

(a) Severance. Executive shall be entitled to receive an amount equal to the sum of Executive’s Base Salary and Executive’s
target annual bonus for the year in which Executive’s termination occurs, payable in a cash lump sum, less applicable withholdings, on the sixtieth (60th) day after the date of the Covered Termination.

 (b) Equity Awards. Each outstanding equity award, including, without limitation, each
stock option and restricted stock award, held by Executive shall automatically become vested and, if applicable, exercisable and any forfeiture restrictions or rights of repurchase thereon shall immediately lapse, in each case, with respect to
one-hundred percent (100%) of the unvested shares of Company common stock subject to such equity award. 
 (c) Continued
Healthcare. If Executive elects to receive continued healthcare coverage pursuant to the provisions of COBRA, the Company shall directly pay, or reimburse Executive for, the premium for Executive and Executive’s covered dependents through
the earlier of (i) the first anniversary of the date of Executive’s termination of employment and (ii) the date Executive and Executive’s covered dependents, if any, become eligible for healthcare coverage under another
employer’s plan(s). Notwithstanding the foregoing, (i) if any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the period of continuation coverage to be, exempt from the application of
Section 409A of the Code under Treasury Regulation Section 1.409A-1(a)(5), or (ii) the Company is otherwise unable to continue to cover Executive under its group health plans without penalty under applicable law (including without
limitation, Section 2716 of the Public Health Service Act), then, in either case, an amount equal to each remaining Company subsidy shall thereafter be paid to Executive in substantially equal monthly installments. After the Company ceases to
pay premiums pursuant to this Section 4(c), Executive may, if eligible, elect to continue healthcare coverage at Executive’s expense in accordance the provisions of COBRA. 

5. Other Terminations. If Executive’s service with the Company is terminated by the Company or by Executive for any or no reason
other than as a Covered Termination, then Executive shall not be entitled to any benefits hereunder other than accrued but unpaid salary, bonus, vacation and expense reimbursement in accordance with applicable law and to elect any continued
healthcare coverage as may be required under COBRA or similar state law. 
 6. Limitation on Payments. Notwithstanding anything in
this Agreement to the contrary, if any payment or distribution Executive would receive pursuant to this Agreement or otherwise (“Payment”) would (a) constitute a “parachute payment” within the meaning of Section 280G of
the Internal Revenue Code of 1986, as amended (the “Code”), and (b) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall either be
(i) delivered in full, or (ii) delivered as to such lesser extent which would result in no portion of such Payment being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and
local income taxes and the Excise Tax, results in the receipt by Executive on an after-tax basis, of the largest payment, notwithstanding that all or some portion the Payment may be taxable under Section 4999 of the Code. The accounting firm
engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. The Company shall bear all expenses with respect to the determinations by such accounting
firm required to be made hereunder. The accounting firm shall provide its calculations to the Company and Executive within fifteen (15) calendar days after the date on which Executive’s right to a Payment is triggered (if requested at that
time by the Company or Executive) or such other time as requested by the Company or Executive.

Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon the Company and Executive. Any reduction in payments and/or benefits pursuant to
this Section 6 will occur in the following order: (1) reduction of cash payments; (2) cancellation of accelerated vesting of equity awards other than stock options; (3) cancellation of accelerated vesting of stock options; and
(4) reduction of other benefits payable to Executive. 
 7. Definition of Terms. The following terms referred to in this
Agreement shall have the following meanings: 
 (a) Base Salary. “Base Salary” means Executive’s annual base salary in
effect immediately prior to Executive’s termination (disregarding any reduction in base salary that would give rise to Executive’s right to a Constructive Termination). 

(b) Cause. “Cause” will be determined in the sole discretion of the Board and will mean misconduct, including:
(i) conviction of any felony or any crime involving moral turpitude or dishonesty; (ii) willful and material breach of Executive’s duties that has not been cured within 30 days after written notice from the Board;
(iii) intentional and material damage to the Company’s property; or (iv) material breach of the Confidential Information Agreement (as defined below). 

(c) Change in Control. “Change in Control” shall mean the occurrence, in a single transaction or in a series of related
transactions, of any one or more of the following events: 
 (i) A transaction or series of transactions (other than an offering of Common
Stock to the general public through a registration statement filed with the Securities and Exchange Commission) whereby any “person” or related “group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2)
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (other than the Company, any of its subsidiaries, an employee benefit plan maintained by the Company or any of its subsidiaries or a “person” that, prior to
such transaction, directly or indirectly controls, is controlled by, or is under common control with, the Company) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities of the
Company possessing more than 50% of the total combined voting power of the Company’s securities outstanding immediately after such acquisition; or 

(ii) During any period of two consecutive years, individuals who, at the beginning of such period, constitute the Board together with any new
director(s) (other than a director designated by a person who shall have entered into an agreement with the Company to effect a transaction described in Section 7(c)(i) or 7(c)(ii)) whose election by the Board or nomination for election by the
Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the two-year period or whose election or nomination for election was previously so
approved, cease for any reason to constitute a majority thereof; or 
 (iii) The consummation by the Company (whether directly involving
the Company or indirectly involving the Company through one or more intermediaries) of (x) a merger, consolidation, reorganization, or business combination or (y) a sale or other disposition of all or


  
 -4- 








 
substantially all of the Company’s assets in any single transaction or series of related transactions or (z) the acquisition of assets or stock of another entity, in each case other
than a transaction: (A) which results in the Company’s voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the Company or
the person that, as a result of the transaction, controls, directly or indirectly, the Company or owns, directly or indirectly, all or substantially all of the Company’s assets or otherwise succeeds to the business of the Company (the Company
or such person, the “Successor Entity”)) directly or indirectly, at least a majority of the combined voting power of the Successor Entity’s outstanding voting securities immediately after the transaction, and (B) after which no
person or group beneficially owns voting securities representing 50% or more of the combined voting power of the Successor Entity; provided, however, that no person or group shall be treated for purposes of this clause (B) as beneficially
owning 50% or more of the combined voting power of the Successor Entity solely as a result of the voting power held in the Company prior to the consummation of the transaction; or 

(iv) The Company’s stockholders approve a liquidation or dissolution of the Company. 

Notwithstanding the foregoing, in no event shall a transaction constitute a Change in Control unless such transaction also constitutes a
“change in control event” within the meaning of Section 409A of the Code and the Treasury regulations promulgated thereunder. 

(d) Change in Control Period. “Change in Control Period” means the period of time beginning three (3) months prior to
and ending twelve (12) months following a Change in Control.

Termination” means any of the following actions taken without Cause by the Company or a successor corporation or entity without Executive’s consent: (i) substantial reduction of Executive’s rate of compensation;

the Company within ninety (90) days of the first occurrence of such event or condition and such resignation is effective within thirty (30) days following the end of such notice period.

 (f) Covered Termination. “Covered Termination” shall mean Executive’s
Constructive Termination or the termination of Executive’s employment by the Company other than for Cause. 
 8. Successors.

 (a) Company’s Successors. Any successor to the Company (whether direct or indirect and whether by purchase, merger,
consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets shall assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same
manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under this Agreement, the term “Company” shall include any successor to the Company’s business
and/or assets which executes and delivers the assumption agreement described in this Section 8(a) or which becomes bound by the terms of this Agreement by operation of law. 

(b) Executive’s Successors. The terms of this Agreement and all rights of Executive hereunder shall inure to the benefit of, and
be enforceable by, Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. 

9. Notices. Notices and all other communications contemplated by this Agreement shall be in writing and shall be deemed to have been
duly given when personally delivered or one day following mailing via Federal Express or similar overnight courier service. In the case of Executive, mailed notices shall be addressed to Executive at Executive’s home address that the Company
has on file for Executive. In the case of the Company, mailed notices shall be addressed to its corporate headquarters, and all notices shall be directed to the attention of its Senior Vice President, Legal and Corporate Development. 

10. Confidentiality; Non-Solicitation. 

(a) Confidentiality. While Executive is employed by the Company, and thereafter, Executive shall not directly or indirectly disclose or
make available to any person, firm, corporation, association or other entity for any reason or purpose whatsoever, any Confidential Information (as defined below). Upon termination of Executive’s employment with the Company, all Confidential
Information in Executive’s possession that is in written or other tangible form (together with all copies or duplicates thereof, including computer files) shall be returned to the Company and shall not be retained by Executive or furnished to
any third party, in any form except as provided herein; provided, however, that Executive shall not be obligated to treat as confidential, or return to the Company copies of any Confidential Information that (i) was publicly known at the
time of disclosure to Executive, (ii) becomes publicly known or available thereafter other than by any means in violation of this Agreement or any other duty owed to the Company by any person or entity, or (iii) is lawfully disclosed to
Executive by a third party. For purposes of this Agreement, the term “Confidential Information” shall mean information disclosed to Executive or known by Executive as a consequence of or through his or her relationship with the Company,
about the customers, employees, business methods, public relations methods, organization, procedures or 

  
 -6- 








 
finances, including, without limitation, information of or relating to customer lists, of the Company and its affiliates. In addition, Executive shall continue to be subject to the Employee
Proprietary Information and Inventions Assignment Agreement entered into between Executive and the Company (the “Confidential Information Agreement”). 

(b) Non-Solicitation. In addition to each Executive’s obligations under the Confidential Information Agreement, Executive shall
not for a period of two (2) years following Executive’s termination of employment for any reason, either on Executive’s own account or jointly with or as a manager, agent, officer, employee, consultant, partner, joint venturer, owner
or stockholder or otherwise on behalf of any other person, firm or corporation, directly or indirectly solicit or attempt to solicit away from the Company any of its officers or employees or offer employment to any person who is an officer or
employee of the Company; provided, however, that a general advertisement to which an employee of the Company responds shall in no event be deemed to result in a breach of this Section 10(b). Executive also agrees not to harass or
disparage the Company or its employees, clients, directors or agents or divert or attempt to divert any actual or potential business of the Company. 

(c) Survival of Provisions. The provisions of this Section 10 shall survive the termination or expiration of the applicable
Executive’s employment with the Company and shall be fully enforceable thereafter. If it is determined by a court of competent jurisdiction in any state that any restriction in this Section 10 is excessive in duration or scope or is
unreasonable or unenforceable under the laws of that state, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the maximum extent permitted by the law of that state. 

11. Dispute Resolution. To ensure the timely and economical resolution of disputes that arise in connection with this Agreement,
Executive and the Company agree that any and all disputes, claims, or causes of action arising from or relating to the enforcement, breach, performance or interpretation of this Agreement, Executive’s employment, or the termination of
Executive’s employment, shall be resolved to the fullest extent permitted by law by final, binding and confidential arbitration, by a single arbitrator, in San Mateo County, California, conducted by Judicial Arbitration and Mediation Services,
Inc. (“JAMS”) under the applicable JAMS employment rules. By agreeing to this arbitration procedure, both Executive and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative
proceeding. The arbitrator shall: (i) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (ii) issue a written arbitration decision, to
include the arbitrator’s essential findings and conclusions and a statement of the award. The arbitrator shall be authorized to award any or all remedies that Executive or the Company would be entitled to seek in a court of law. The Company
shall pay all JAMS’ arbitration fees in excess of the amount of court fees that would be required if the dispute were decided in a court of law. Nothing in this Agreement is intended to prevent either Executive or the Company from obtaining
injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Notwithstanding the foregoing, Executive and the Company each have the right to resolve any issue or dispute over intellectual property rights by
Court action instead of arbitration.

(a) Section 409A. 

(i) Separation from Service. Notwithstanding any provision to the contrary in this Agreement, no amount deemed deferred compensation
subject to Section 409A of the Code shall be payable pursuant to Sections 3 or 4 unless Executive’s termination of employment constitutes a “separation from service” with the Company within the meaning of Section 409A of the
Code and the Department of Treasury regulations and other guidance promulgated thereunder (“Separation from Service”) and, except as provided under Section 12(a)(ii) of this Agreement, any such amount shall not be paid, or in the case
of installments, commence payment, until the sixtieth (60th) day following Executive’s Separation from Service. Any installment payments that would have been made to Executive during the
sixty (60) day period immediately following Executive’s Separation from Service but for the preceding sentence shall be paid to Executive on the sixtieth (60th) day following
Executive’s Separation from Service and the remaining payments shall be made as provided in this Agreement.

Employee. Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed at the time of his or her separation from service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code,

Executive’s benefits shall not be provided to Executive prior to the earlier of (a) the expiration of the six (6)-month period measured from the date of the Executive’s Separation from Service or (b) the date of Executive’s
death. Upon the first business day following the expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Section 12(a)(ii) shall be paid in a lump sum to Executive, and any remaining
payments due under this Agreement shall be paid as otherwise provided herein. 
 (iii) Expense Reimbursements. To the extent that
any reimbursements payable pursuant to this Agreement are subject to the provisions of Section 409A of the Code, any such reimbursements payable to Executive pursuant to this Agreement shall be paid to Executive no later than December 31
of the year following the year in which the expense was incurred, the amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year, and Executive’s right to reimbursement under this
Agreement will not be subject to liquidation or exchange for another benefit. 
 (b) Waiver. No provision of this Agreement shall be
modified, waived or discharged unless the modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive). No waiver by either party of any breach of, or of
compliance with, any condition or provision of this Agreement by the other party shall be considered a waiver of any other condition or provision or of the same condition or provision at another time.

the entire understanding of the parties hereto with respect to the subject matter hereof and supersede all prior arrangements and understandings regarding same, including, without limitation, the Company’s Change in Control Benefit Plan and any
accelerated vesting provisions of Executive’s offer letter agreement, employment agreement and/or stock option agreement. 
 (d)
Choice of Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of California. 

(e) Severability. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision hereof, which shall remain in full force and effect. 
 (f) Counterparts. This Agreement may be
executed in counterparts, each of which shall be deemed an original, but all of which together will constitute one and the same instrument.
