Exhibit 99.1

This Separation Agreement (the “Agreement”) by and between Xxxxxxx X’Xxxxx (“Executive”) and Xxxxx Therapeutics, Inc., a Delaware corporation (the “Company”), is made effective eight (8) days after Executive’s signature hereto (the “Effective Date”), unless Executive revokes his acceptance of this Agreement as provided in Section 5(c) below, with reference to the following facts:

A. Executive’s employment with the Company and status as an officer and employee of the Company and each of its affiliates will end effective upon the Separation Date (as defined below).

B. Executive and the Company want to end their relationship amicably and also to establish the obligations of the parties including, without limitation, all amounts due and owing to Executive.

C. The payments and benefits being made available to Executive pursuant to this Agreement are intended to satisfy all outstanding obligations under that certain Change in Control Severance Agreement by between Executive and the Company (the “Severance Agreement”).

NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth, the parties agree as follows:

1. Separation Date. Executive acknowledges and agrees that his status as an officer and employee of the Company will end effective as of May 19, 2017 (the “Separation Date”). Executive hereby agrees to execute such further document(s) as shall be determined by the Company as necessary or desirable to give effect to the end of Executive’s status as an officer of the Company and, if applicable, officer and/or director of any of its subsidiaries; provided that such documents shall not be inconsistent with any of the terms of this Agreement.

2. Final Paycheck; Payment of Accrued Wages and Expenses.

(a) Final Paycheck. As soon as administratively practicable on or after the Separation Date, the Company will pay Executive all accrued but unpaid base salary and all accrued and unused vacation earned through the Separation Date, subject to standard payroll deductions and withholdings. Executive is entitled to these payments regardless of whether Executive executes this Agreement.

(b) Business Expenses. The Company shall reimburse Executive for all outstanding expenses incurred prior to the Separation Date which are consistent with the Company’s policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to the Company’s requirements with respect to reporting and documenting such expenses, including, without limitation, expenses incurred pursuant to Executive’s services as a director of any of the Company’s subsidiaries.

3. Separation Payments and Benefits. Without admission of any liability, fact or claim, the Company hereby agrees, subject to this Agreement becoming effective and irrevocable, as well as Executive’s performance of his continuing obligations pursuant to this Agreement and that certain Confidentiality, Covenant Not To Compete & Arbitration Agreement by and between the Company and Executive dated April 11, 2016 (the “Confidentiality Agreement”) (including, without limitation, the non-competition and non-solicitation restrictive covenants set forth therein for the

periods set forth in the Confidentiality Agreement), to provide Executive the severance benefits set forth below. Specifically, the Company and Executive agree as follows:

(a) Severance. The Company shall pay to Executive four hundred fifty-nine thousand dollars ($459,000), which represents the sum of (i) twelve (12) months of Executive’s annual base salary and (ii) one (1) times Executive’s target annual bonus assuming achievement of performance goals at target, in each case, at the rate in effect immediately prior to the Separation Date, in a single cash lump sum. Such payment shall be made, less applicable withholdings and deductions, on or as soon as reasonably practicable following the first regularly scheduled payroll date following the date this Agreement becomes effective and irrevocable.

(b) Healthcare Continuation Coverage. 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, that portion of the premium for Executive and Executive’s covered dependents necessary such that Executive contributes the same amount to COBRA coverage as Executive contributed to medical, dental and vision coverage prior to the date of this Agreement, such payment or reimbursement to continue until the earlier of (i) the last day of the twelfth (12^th) full calendar month anniversary following the date this Agreement becomes effective and irrevocable or (ii) the date Executive becomes eligible for comparable coverage under another employer’s plans. After the Company ceases to pay premiums pursuant to the preceding sentence, Executive may, if eligible, elect to continue healthcare coverage at Executive’s expense in accordance with the provisions of COBRA. Executive acknowledges that he shall be solely responsible for all matters relating to Executive’s continuation of coverage pursuant to COBRA, including, without limitation, Executive’s election of such coverage and his timely payment of premiums.

(c) Equity Awards. Each outstanding and unvested equity award, including, without limitation, each stock option and restricted stock award, held by Executive (collectively, the “Equity Awards”) shall 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 that number of unvested shares underlying the Equity Awards as of the Separation Date. The Equity Awards shall otherwise be subject to the terms of the applicable award agreements (the “Equity Award Agreements”).

(d) Taxes. Executive understands and agrees that all payments under this Section 3 will be subject to appropriate tax withholding and other deductions. To the extent any taxes may be payable by Executive for the benefits provided to him by this Section 3 beyond those withheld by the Company, Executive agrees to pay them himself and to indemnify and hold the Company and the other entities released herein harmless for any tax claims or penalties, and associated attorneys’ fees and costs, resulting from any failure by him to make required payments. To the extent that any reimbursements payable pursuant to this Agreement are subject to the provisions of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), such reimbursements 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.

(e) SEC Reporting. Executive acknowledges that to the extent required by the Securities Exchange Act of 1934, as amended (the “Exchange Act”), he will have continuing obligations under Section 16(a) and 16(b) of the Exchange Act to report Executive’s matching transactions in Company common stock for six (6) months following the Separation Date. Executive hereby agrees not to undertake, directly or indirectly, any reportable transactions involving the common stock of the Company until the end of such six (6) month period.

(f) Sole Separation Benefit. Executive agrees that the payments provided by this Section 3 are not required under the Company’s normal policies and procedures and are provided as a severance solely in connection with this Agreement. Executive acknowledges and agrees that the payments referenced in this Section 3 constitute adequate and valuable consideration, in and of themselves, for the promises contained in this Agreement.

4. Full Payment. Executive acknowledges that the payment and arrangements herein shall constitute full and complete satisfaction of any and all amounts properly due and owing to Executive as a result of his employment with the Company and the termination thereof. Executive further acknowledges that, other than the Equity Award Agreements, the Confidentiality Agreement and the Indemnification Agreement between Executive and the Company (the “Indemnification Agreement”), this Agreement shall supersede each agreement entered into between Executive and the Company regarding Executive’s employment, including, without limitation, any offer letter, the Severance Agreement and that certain employment agreement by and between Executive and the Company dated April 25, 2016, and each such agreement shall be deemed terminated and of no further effect as of the Separation Date.

5. Executive’s Release of the Company.
