 Exhibit 10.7 

EXECUTIVE EMPLOYMENT AGREEMENT 

THIS EXECUTIVE EMPLOYMENT AGREEMENT (this “Agreement”) is made effective as of September 16, 2013, by and between Akebia
Therapeutics, Inc., a Delaware corporation (the “Company”), and John P. Butler, an individual resident in the Commonwealth of Massachusetts (“Executive”). 

1. Employment; Duties; Full Time Employment. The Company hereby agrees to employ Executive, and Executive hereby accepts employment, as
President and Chief Executive Officer of the Company, with such employment to commence on September 16, 2013 (the “Commencement Date”). In such capacity, Executive shall perform such Executive duties and exercise such powers
for the Company and its subsidiaries as the Board of Directors of the Company (the “Board”) may lawfully assign to or vest in Executive from time to time. Executive covenants and agrees that, at all times during the Term (as defined
below), Executive shall devote Executive’s full business time and efforts to Executive’s duties as an employee of the Company and that Executive will not, directly or indirectly, engage or participate in any other business or professional
activities during the Term, other than (a) non-conflicting personal investments managed on Executive’s personal time, (b) activities for non-profit institutions (including, but not limited to, participating on boards of directors),
and (c) activities or commitments set forth and described on Appendix A (Section 1) hereto, provided that such activities do not interfere or conflict with Executive’s obligations hereunder. 

2. Place of Performance. Executive’s principal place of business for the performance of his duties under this Agreement shall be
in the greater Boston, Massachusetts metropolitan area. Executive shall also travel as reasonably necessary or appropriate to perform his duties hereunder, including, but not limited to, trailing to the Company’s offices in Cincinnati, Ohio. At
no time during the Term shall Executive be required to relocate to the Cincinnati, Ohio area or otherwise be required to relocate his residence from the greater Boston, Massachusetts metropolitan area. 

3. Term. The Company agrees to employ Executive, and Executive agrees to serve the Company, on an “at will” basis,
which means that either the Company or Executive may terminate Executive’s employment with the Company at any time, with or without Cause, as provided in Section 6 below. The period commencing with the Commencement Date and ending
on the effective date of any termination of employment in accordance with the provisions hereof shall constitute the term of this Agreement (the “Term”). 

4. Compensation and Benefits. During the Term, the Company shall provide Executive with the following compensation and benefits: 

(a) Base Salary. The Company shall pay Executive a base salary (“Base Salary”) at the rate of $425,000 per annum (less
applicable deductions and withholdings), payable in periodic payments in accordance with the Company’s normal payroll practices. During the Term, Executive’s compensation shall be reviewed by the Board from time to time and at least once
every 12 months. Any increase or decrease in Base Salary (together with the then existing Base Salary) shall serve as the “Base Salary” under this Agreement. Any such decrease in Base Salary, however, shall constitute Good Reason under
Section 6(e) of this Agreement. 

 (b) Discretionary Bonuses. Executive will be eligible to receive an annual bonus in an
amount up to 30% of Executive’s Base Salary. The exact amount of the actual bonus awarded to Executive for any given year, if any, shall be determined by the Board in its sole discretion based upon its consideration of the Company’s
performance and Executive’s performance against objectives established by the Board for the year, in consultation with Executive. Except as otherwise may be required by applicable law, Executive must remain an employee through the end of the
calendar year in order to earn a bonus for that year. Executive will not earn any bonus (including a prorated bonus) for any year if Executive’s employment terminates for any reason before the end of such year. Any annual bonus shall be paid by
March 15 of the following calendar year. 
 (c) Stock Ownership. On or by the Effective Date, Executive shall be awarded 350,000
options to acquire shares of the Common Stock of the Company (“Stock Options”), which Stock Options represent approximately 4.3% of the Company’s Common Stock outstanding as of the Effective Date on a fully-diluted and
as-converted basis. Except for the foregoing Stock Options, and except as otherwise may be determined by the Board from time to time after the date of this Agreement in its discretion Executive shall not have any right to be issued shares of the
Company’s capital stock or options, warrants or other rights to acquire any capital stock of the Company. 
 (d) Other Compensation
and Benefits. In addition to the compensation specified above in this Section 4. Executive shall be entitled to the following benefits during the Term, all on the terms offered or maintained by the Company to, for or on behalf of its
senior executives: vacation, holidays and sick leave, and subject to eligibility therefor, the right to participate in any profit sharing plan, retirement plan, 401(k) plan, group medical plan, group dental plan, group life insurance plan and/or
other health or insurance plan maintained by the Company for its senior executives generally and, if applicable, their family members. Executive will be eligible for the paid holidays as are generally made available to employees of the Company. 

(e) Vacation. The Executive shall be entitled to four weeks paid vacation per calendar year to be taken at such times as may be
approved by the Board (which is more than the normal amount defined in the Akebia Employee Handbook). An aggregate of up to 1 week of unused vacation time may be carried over at the end of a calendar year. Upon termination of the Executive’s
employment, the Company will pay the Executive for unused vacation at the Executive’s Base Salary rate (subject to normal deductions and withholding amounts) on the next regularly scheduled pay date immediately following the termination date,
or earlier if required by applicable law. 
 5. Business Expenses. The Company shall reimburse Executive for all reasonable and
necessary business and travel expenses incurred by Executive in the performance of Executive’s duties under this Agreement. Such expenses shall be reimbursed in accordance with the Company’s guidelines, limits and procedures relating
thereto and upon presentation of proper expense vouchers or receipts therefor. 

  
 2 

 6. Termination. 

(a) Termination on Death or Disability. The Term will terminate automatically and immediately upon Executive’s death or, upon 30
days prior written notice from the Company, in the event of Executive’s Disability. For purposes of this Section 6, “Disability” means that Executive, at the time notice is given, has been unable to substantially
perform Executive’s duties under this Agreement for not less than sixty (60) work days within a six (6) consecutive month period as a result of Executive’s incapacity due to physical or mental illness. Upon any termination for
death or Disability, Executive will not be entitled to any further compensation from the Company, including severance pay, pay in lieu of notice or any other such compensation (other than accrued salary and bonus, and accrued and unused vacation,
through Executive’s last day of employment). 
 (b) Termination by the Company Without Cause; Termination by the Executive for Good
Reason. During the Term, the Company shall be entitled to terminate Executive’s employment without Cause (as defined below), and the Executive is also entitled to terminate his employment for Good Reason (as defined below), in which case
Executive shall be entitled to receive the following severance benefits (the “Severance Payments”), in addition to accrued salary and bonus, and accrued and unused vacation, through Executive’s last day of employment:
(i) Executive shall be entitled to severance pay in the form of continuation of Executive’s Base Salary in effect on the effective date of termination for a period of twelve (12) months after the date of such termination, to be paid
periodically in accordance with the Company’s normal payroll practices and subject to standard payroll deductions and withholdings; (ii) if Executive timely elects continued coverage under COBRA, then (A) the Company shall make such
COBRA coverage (or equivalent medical benefits after the termination of COBRA) available for at least 18 months following termination and (B) the Company shall pay the COBRA premiums necessary to continue Executive’s medical insurance
coverage in effect on the termination date for a period of twelve (12) months following Executive’s termination (provided that such COBRA continuation and reimbursement shall terminate upon commencement of new employment by an employer
that offers health care coverage to its employees); and (iii) a pro-rata portion of the Executive’s annual target bonus for the calendar year in which the termination occurs. 

Notwithstanding the foregoing, all Severance Payments under this Agreement are conditional on Executive (i) complying with the provisions
of Section 7 below, and (ii) delivering prior to receipt of such severance payments, an effective, general release of claims in favor of the Company or its successor, its subsidiaries and their respective directors, officers and
stockholders in a form acceptable to the Company or its successor. 
 In the event that the Company determines that any severance benefit
provided hereunder fails to satisfy the distribution requirement of Section 409A(a)(2)(A) of the Internal Revenue Code (“Code”) as a result of Section 409A(a)(2)(B)(i) of the Code, then if an accelerated payment of such
benefits would cause such benefit not to be subject to the provisions of Section 409A(a)(1) of the Code, the payment of such benefits shall be accelerated to the minimum extent necessary so that the benefit is not subject to the provisions of
Section 409A(a)(1) of the Code. 

  
 3 

 (The payment schedule as revised after the application of the preceding sentence shall be
referred to as the “Revised Payment Schedule.”) However, in the event the accelerated payment of such benefits would not avoid the application of Section 409A (a)(1) of the Code, the payment of such benefits shall not be made
pursuant to the original payment schedule or the Revised Payment Schedule and instead the payment of such benefits shall be delayed to the minimum extent necessary so that such benefits are not subject to the provisions of Section 409A(a)(1) of
the Code. The Board may attach conditions to or adjust the amount paid pursuant to this Section 6(b)(iv) to preserve, as closely as possible, the economic consequences that would have applied in the absence of this
Section 6(b)(iv); provided, however, that no such condition or adjustment shall result in the payments being subject to Section 409A(a)(1) of the Code. 

Notwithstanding any other provisions in this Agreement, it shall be a prerequisite of any termination by Executive for Good Reason that
Executive shall have given the Company written notice within sixty (60) days following the date Executive becomes aware of the event or events giving rise to Good Reason, specifying in reasonable detail the nature and circumstances of such Good
Reason, and giving the Company thirty (30) days to cure any such Good Reason prior to any such termination, and if uncured, the termination for Good Reason must occur within ninety (90) days of the end of such cure period. 

(c) Termination for Cause; Resignation. The Company may terminate Executive’s employment at any time for Cause, and Executive may
resign at any time. Termination for Cause shall be effective on the date the Company gives notice to Executive of such termination in accordance with this Agreement. Resignation by Executive shall be effective on the date Executive gives notice to
the Company of such resignation in accordance with this Agreement. In the event of the Company’s termination of the Term for Cause or Executive’s resignation from Executive’s employment, Executive will not be entitled to any further
compensation from the Company, including severance pay, pay in lieu of notice or any other such compensation (other than accrued salary and bonus, and accrued and unused vacation, through Executive’s last day of employment). 

(d) Cause. For purposes of this Agreement, “Cause” shall mean (i) Executive’s failure to substantially
perform Executive’s duties under this Agreement for reasons other than death or Disability, which failure, if curable, is not cured to the reasonable satisfaction of the Board during the thirty (30) day period following written notice of
such failure from the Company; (ii) Executive’s material failure or refusal to comply with reasonable written policies, standards and regulations established by the Company from time to time which failure, if curable, is not cured to the
reasonable satisfaction of the Board during the thirty (30) day period following written notice of such failure from the Company; (iii) the proven commission by Executive of (x) an act of dishonesty or constituting common law fraud,
embezzlement or a felony or (y) any tortious act, unlawful act or malfeasance that causes material harm to the Company’s standing, condition or reputation; or (iv) any material breach by Executive of the provisions of this Agreement,
which breach, if curable, is not cured to the reasonable satisfaction of the Board during the thirty (30) day period following written notice of such breach from the Company. The Board (excluding Executive if Executive is at such time a member
of the Board) shall in good faith make all determinations relating to termination, including without limitation any determination regarding Cause, pursuant to this Section 6(d). 

  
 4 

 (e) Good Reason. For purposes of this Agreement, “Good Reason” shall mean
any of the following without the consent of the Executive: (i) a material diminution in the Executive’s position, duties or responsibilities from those held by or assigned to the Executive as of the Effective Date, (ii) a reduction of
the Executive’s Base Salary, (iii) a material reduction of the Executive’s benefits or bonus/incentive compensation opportunities provided to the Executive as then in effect, so long as he is the only executive to suffer such a
reduction, or (iv) requiring the Executive to relocate beyond a fifty (50) mile radius of the Executive’s then current residence. 

(f) Removal from any Boards and Positions. Notwithstanding provision in this Agreement, if Executive’s employment is terminated
under this Agreement for any reason, Executive shall be deemed to resign (i) from the Board or board of directors of any affiliate of the Company or any other board to which he has been appointed or nominated by or on behalf of the Company, and
(ii) from any position with the Company or any affiliate of the Company, including, but not limited to, as an officer of the Company or any of its affiliates. 

7. Company Matters: Restrictive Covenants. 

(a) Confidential Information. Executive will have access to and will participate in the development of and will be acquainted with
confidential or proprietary information and trade secrets related to the business of the Company and its affiliates, including but not limited to (i) customer lists; related records and compilations of information; the identity, lists or
descriptions of any new customers, referral sources or organizations; financial statements; cost reports or other financial information; contract proposals or bidding information; business plans; training and operations methods and manuals;
personnel records; software programs; reports and correspondence; and management systems, policies or procedures, including related forms and manuals, (ii) information pertaining to future developments such as future marketing or acquisition
plans or ideas and potential new business locations; and (iii) all other tangible and intangible property and intellectual property which is used in the business and operations of the Company and its affiliates but not made public. The
foregoing is collectively referred to as the “Confidential Information.” The term Confidential Information shall not include any information (x) that is or becomes generally publicly available (other than as a result of
violation of this Agreement by Executive), or (y) that Executive receives on a non-confidential basis from a source (other than the Company, its affiliates or their representatives) that is not known by Executive to be bound by an obligation of
secrecy or confidentiality to any of the Company or its affiliates. Executive shall not disclose, use or make known for Executive’s or another’s benefit other than for the benefit of the Company and its affiliates any Confidential
Information or use such Confidential Information in any way. Upon the termination of Executive’s employment with the Company for any reason, Executive shall immediately return to the Company all Confidential Information in whatever form
maintained (including, without limitation, computer discs and other electronic media). 
 (b) Non-Competition. During
Executive’s employment with the Company and for the one-year period immediately following the termination of Executive’s employment with the Company, Executive will not directly or indirectly (whether as an officer, director, stockholder,
partner, proprietor, associate, representative, consultant or in any capacity whatsoever) engage in, become financially interested in, be employed by or have any business 

  
 5 

 
connection with any person, corporation, firm, partnership or any other entity whatsoever which competes with the Company in any area where the Company operates, or has operated at any time
during Executive’s employment with the Company. Notwithstanding the foregoing, the ownership by Executive of not more than three percent (3%) of the shares of stock of any corporation having a class of equity securities actively traded on
a national securities exchange or on the Nasdaq Stock Market shall not be deemed to violate the prohibitions this Section 7(b). 
 (c)
Nonsolicitation of Customers. During Executive’s employment with the Company and for the one-year period immediately following the termination of Executive’s employment with the Company, Executive shall not solicit, directly or
indirectly, any customers or prospective customers of the Company with whom Executive had contact on behalf of the Company during Executive’s employment with the Company. 

(d) Nonsolicitation of Employees. During Executive’s employment with the Company and for the one-year period immediately following
the termination of Executive’s employment with the Company, Executive shall not solicit or hire, directly or indirectly, on Executive’s behalf or on behalf of any other person or entity, any person employed by the Company except with the
specific written consent of the Company. 
 (e) Certain Representations. Executive represents that Executive’s experience,
capabilities and circumstances are such that the provision of this Agreement will not prevent Executive from earning a livelihood. Executive further agrees that the limitations set forth in this Agreement (including, without limitation, the time and
territorial limitations) are reasonable and properly required for the adequate protection of the current and future businesses of the Company. Executive further acknowledges that a remedy at law for any breach or threatened breach of the provisions
of this Agreement would be inadequate and will cause immediate and irreparable harm to the Company in a manner that cannot be measured nor adequately compensated in damages. Executive further acknowledges that in the event of any such breach and in
addition to any and all other remedies that it may have at law or in equity, the Company shall be entitled to seek temporary, preliminary and permanent injunctive relief to restrain such breach by Executive, and the prevailing party in any such
proceeding shall be entitled to recover all associated costs and expenses, including reasonable attorneys’ fees, from the non-prevailing party. Nothing contained herein shall restrict or limit in any manner the Company’s right to seek and
obtain any form of relief, legal or equitable, against Executive in an action brought to enforce its rights hereunder. 
 (f)
Intellectual Property. Except as otherwise set forth and described on Appendix A (Section 7(f)) hereto, all ideas, concepts, inventions, improvements, programs, information technology, derivative works, processes, configurations, data,
procedures, designs, techniques and other works of authorship and development made, conceived or reduced to practice by Executive, either solely or in collaboration with others, during Executive’s employment with the Company, including but not
limited to all copyright, trademark, patent, trade secret and intellectual property rights associated therewith, shall become and remain the exclusive property of the Company. Executive hereby assigns to the Company any and all of Executive’s
right, title and interest in and to any of the foregoing, and Executive waives any claim that Executive may have thereto. Executive will promptly disclose in writing to the Company all such ideas, concepts, inventions, improvements, programs,
information technology, 

  
 6 

 
derivative works, processes, configurations, data, procedures, designs, techniques and other works of authorship and development, and will cooperate fully with the Company in confirming and
protecting the Company’s ownership rights therein. The work product resulting from the Executive’s employment with the Company is work made for hire. 

(g) Ventures. If, during the Term, Executive is engaged in or associated with the planning or implementing of projects, programs or
ventures involving the Company and third parties, all rights in such projects, programs and ventures shall belong to the Company (or the third party, to the extent provided in any agreement between the Company and the third party). Except as
formally approved by the Company, Executive shall not be entitled to any interest in such project, program or venture or to any commission, finder’s fee or other compensation in connection therewith other than the salary or other compensation
to be paid to Executive as provided in this Agreement. 
 8. Miscellaneous. 

(a) Withholding Taxes. The Company may withhold from all salary, bonus or other benefits payable under this Agreement all federal,
state, city or other taxes as shall be required pursuant to any law or governmental regulation or ruling. 
 (b) Entire Agreement;
Binding Effect. This Agreement sets forth the entire understanding between the parties as to the Subject matter of this Agreement and supersedes all prior agreements, commitments, representations, writings and discussions between them (whether
written or oral) on the subject matters herein; and neither of the parties shall be bound by any obligations, conditions, warranties or representations with respect to the subject matter of the foregoing except as expressly provided herein or
therein or as duly set forth on or subsequent to the date hereof in a written instrument signed by the proper and fully authorized representative of the party to be bound hereby. This Agreement is binding on Executive and on the Company and
Executive and their respective successors and assigns (whether by assignment, by operation of law or otherwise); provided that neither this Agreement nor any rights or obligations hereunder may be assigned by Executive or the Company without the
prior written consent of the other party (except that the Company shall be entitled to assign this Agreement in connection with the sale of all or substantially all of the Company’s assets, or a merger or consolidation in which the Company is
not the surviving entity). 
 (c) Absence of Conflict. Executive represents and warrants that Executive’s employment by the
Company as described herein will not conflict with and will not be constrained by any prior employment or consulting agreement or relationship. 

(d) Voluntary Nature of Agreement; Legal Rights. Executive is executing this Agreement voluntarily and without any duress or undue
influence by the Company or anyone else. Executive acknowledges that Executive has had the opportunity to consult with an attorney regarding the provisions of this Agreement and has either obtained such advice of counsel or knowingly waived the
opportunity to seek such advice. Executive has carefully read this Agreement and has asked any questions needed for Executive to understand the terms, consequences and binding effect of this Agreement and fully understand it, including that
Executive is waiving Executive’s right to a jury trial. 

  
 7 

 (e) Waivers. No party shall be deemed to have waived any right, power or privilege under
this Agreement or any provisions hereof unless such waiver shall have been duly executed in writing and acknowledged by the party to be charged with such waiver. The failure of any party at any time to insist on performance of any of the provisions
of this Agreement shall in no way be construed to be a waiver of such provisions, nor in any way to affect the validity of this Agreement or any part hereof. No waiver of any breach of this Agreement shall be held to be a waiver of any other
subsequent breach. 
 (f) Notices. All notices, approvals, consents, requests or demands required or permitted to be given under this
Agreement shall be in writing and shall be deemed sufficiently given (i) upon delivery, if delivered by hand (ii) one business day after transmission, if sent by facsimile (confirmation received) or (iii) one business day after the
