* This percentage is calculated based upon 21,414,885 shares of common stock outstanding of Synlogic, Inc. (the “Issuer”), as set forth in the Issuer’s Prospectus Supplement Form 424B5 filed with the Securities and Exchange Commission on January 23, 2018.

         
Item 1.
Security and Issuer
 
This Amendment No. 1 (“Amendment No. 1”) to Schedule 13D supplements and amends the Statement on Schedule 13D originally filed by OrbiMed Advisors LLC, OrbiMed Capital GP VI LLC and Samuel D. Isaly with the Securities and Exchange Commission (the “SEC”) on September 7, 2017 (the “Statement”).  This Statement relates to the common stock, par value $0.001 per share (the “Shares”), of Synlogic, Inc., a Delaware corporation formerly known as Mirna Therapeutics, Inc. (the “Issuer”), with its principal offices located at 200 Sidney Street, Suite 320, Cambridge, Massachusetts 02139.  The Shares are listed on The NASDAQ Global Market under the ticker symbol “SYBX”.  Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.
 
This Amendment No. 1 is being filed to report that Samuel D. Isaly, who was previously identified as a reporting person, has ceased to be the beneficial owner of more than five percent of the outstanding Shares, and to report that the beneficial ownership of the outstanding Shares of the Issuer held by the Reporting Persons increased by more than one percent following the purchase of Shares as more particularly described in Item 3 below.
 
 
Item 2.
Identity and Background
 
(a)          This Statement is being filed by OrbiMed Advisors LLC (“Advisors”), a limited liability company organized under the laws of Delaware, and OrbiMed Capital GP VI LLC (“GP VI”), a limited liability company organized under the laws of Delaware (collectively, the “Reporting Persons”).
 
(b) – (c), (f)  Advisors, a registered investment adviser under the Investment Advisers Act of 1940, as amended, is the sole managing member of GP VI, which is the sole general partner of OrbiMed Private Investments VI, LP (“OPI VI”), which holds Shares, as more particularly described in Item 3 below.  Advisors has its principal offices at 601 Lexington Avenue, 54th Floor, New York, New York 10022.
 
GP VI has its principal offices at 601 Lexington Avenue, 54th Floor, New York, New York 10022.
 
The directors and executive officers of Advisors and GP VI are set forth on Schedules I and II, attached hereto.  Schedules I and II set forth the following information with respect to each such person:
 
(i)            name;
 
(ii)           business address;
 
(iii)         present principal occupation or employment and the name, principal business and address of any corporation or other organization in which such employment is conducted; and
 
(iv)          citizenship.
 
(d) – (e)  During the last five years, neither the Reporting Persons nor any person named in Schedule I or II have been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
 

 
Item 3.
Source and Amount of Funds or Other Consideration
 
 On January 26, 2018, the Issuer closed a direct registered offering announced on January 23, 2018 (the “Offering”).  The Issuer issued in the Offering a total of 5,130,000 Shares at a purchase price of $9.75 per share with gross proceeds of $50,017,500 (the “Share Issuance”). Advisors and GP VI, pursuant to their authority under the limited partnership agreement of OPI VI, as more particularly referred to in Item 6 below, caused OPI VI to purchase 715,000 Common Stock of the Issuer.
 
The source of funds for the purchases described above was the working capital of OPI VI and capital contributions made to OPI VI.
 
As a result of the transactions described in this Item 3, (i) GP VI, as the general partner of OPI VI, and (ii) Advisors, as the managing member of GP VI may each be deemed to be the beneficial owner of approximately 9.48% of the outstanding Shares.
 
Item 4.
Purpose of Transaction
 
The Reporting Persons caused OPI VI to acquire Shares for the purpose of making an investment in the Issuer and not with the intention of acquiring control of the Issuer’s business on behalf of OPI VI.
 
The Reporting Persons from time to time intend to review their investment in the Issuer on the basis of various factors, including the Issuer’s business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s Shares in particular, as well as other developments and other investment opportunities.  Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time.  If the Reporting Persons believe that further investment in the Issuer is attractive, whether because of the market price of the Shares or otherwise, they may acquire Shares or other securities of the Issuer either in the open market or in privately negotiated transactions.  Similarly, depending on market and other factors, the Reporting Persons may determine to dispose of some or all of the Shares currently owned by the Reporting Persons or otherwise acquired by the Reporting Persons either in the open market or in privately negotiated transactions.
 
Except as set forth in this Statement, the Reporting Persons have not formulated any plans or proposals which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of the assets of the Issuer or any of its subsidiaries; (d) any change in the present Board of Directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) any material change in the Issuer’s capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer’s business or corporate structure; (g) any change in the Issuer’s charter or bylaws or other instrument corresponding thereto or other action which may impede the acquisition of control of the Issuer by any person; (h) causing a class of the Issuer’s securities to be deregistered or delisted from a national securities exchange or to cease to be authorized to be quoted in an inter‑dealer quotation system of a registered national securities association; (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) any action similar to any of those enumerated above.

Item 5.
Interest in Securities of the Issuer
 
(a)-(b)   As of the date of this filing, the Reporting Persons may be deemed, for purposes of Rule 13d-3 of the Securities Exchange Act of 1934, as amended, directly or indirectly, including by reason of their mutual affiliation, to be the beneficial owners of the Shares described in Item 6 below  Based upon information contained in the Issuer’s Prospectus on Form 424B5, filed with the Securities and Exchange Commission on January 23, 2018, such Shares deemed to be indirectly beneficially owned by the Reporting Persons constitutes approximately 9.48% of the issued and outstanding Shares. Advisors, pursuant to its authority as the sole managing member of GP VI, the sole general partner of OPI VI, may be deemed to indirectly beneficially own the Shares held by OPI VI.  GP VI, pursuant to its authority as the general partner of OPI VI, may be deemed to indirectly beneficially own the Shares held by OPI VI.  As a result, Advisors and GP VI share the power to direct the vote and to direct the disposition of the Shares held by OPI VI.    Advisors exercises this investment and voting power through a management committee comprised of Carl L. Gordon, Sven H. Borho and Jonathan T. Silverstein, each of whom disclaims beneficial ownership of the Shares held by OPI VI.
 

 
(c)          Except as disclosed in Item 3, the Reporting Persons have not effected any transactions in the Shares during the past sixty (60) days.
 
(d)          Not applicable.
 
(e)          As of January 24, 2018 Samuel D. Isaly, who was previously identified as a reporting person, has ceased to be the beneficial owner of more than five percent of the outstanding Shares.
 
 
 
Item 6.
Contracts, Arrangements, Understandings or Relationship with Respect to Securities of the Issuer
 
In addition to the relationships between the Reporting Persons described in Items 2, 3 and 5 above, GP VI is the sole general partner of OPI VI, pursuant to the terms of the limited partnership agreement of OPI VI.  Advisors is the sole managing member of GP VI, pursuant to the terms of the limited liability company agreement of GP VI.  Pursuant to these agreements and relationships, Advisors and GP VI have discretionary investment management authority with respect to the assets of OPI VI.  Such authority includes the power of GP VI to vote and otherwise dispose of securities purchased by OPI VI.  The number of Shares attributable to OPI VI is 2,029,996.  Advisors and GP VI may each be considered to hold indirectly 2,029,996 Shares. 

Chau Khuong (“Khuong”), a Private Equity Partner at Advisors, has been a member of the Board of Directors of the Issuer since September 2013, and, accordingly, the Reporting Persons may have the ability to affect and influence control of the Issuer. From time to time, Khuong may receive additional stock options or other awards of equity‑based compensation pursuant to the Issuer’s compensation arrangements for non‑employee directors.  Khuong is obligated to transfer any Shares issued under any such stock options or other awards, or the economic benefit thereof, to the Reporting Persons, which will in turn ensure that such shares or economic benefits are provided to OPI VI. 

 
Lock‑up Agreement
 
In connection with the Offering, certain of the Issuer’s pre-offering stockholders, including OPI VI, entered into agreements (each, a “Lock Up Agreement”), pursuant to which such parties have agreed not to, except in limited circumstances, sell or transfer, or engage in swap or similar transactions with respect to the Shares, including, as applicable, Shares received in the Offering and issuable upon exercise of certain warrants and options, until 90 days from the closing of the Offering.
 
The foregoing description of the Lock‑Up Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Lock‑Up Agreement, a copy of which is included in this Statement as Exhibit 2 and incorporated herein by reference.

c/o Leerink Partners LLC
299 Park Avenue, 21st floor
New York, NY 10171

Re:          Proposed Public Offering by Synlogic, Inc.
 
Ladies and Gentlemen:
 
The undersigned, a stockholder, officer and/or director of Synlogic, Inc., a Delaware corporation (the “Company”), understands that Leerink Partners LLC (“Leerink”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company providing for the public offering (the “Public Offering”) of shares (the “Securities”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”).  In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder, an officer and/or a director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement (collectively, the “Underwriters”) that, during the period beginning on the date hereof and ending on the date that is 90 days from the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of Leerink, on behalf of the Underwriters, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (collectively, the “Lock-Up Securities”), or exercise any right with respect to the registration of any of the Lock-Up Securities, or file or cause to be filed any registration statement in connection therewith, under the Securities Act of 1933, as amended, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise.
 
Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer Lock-Up Securities without the prior written consent of Leerink, provided, in each case, that (1) Leerink receives a signed lock-up agreement for the balance of the Lock-Up Period from each donee, trustee, distributee, or transferee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported with the Securities and Exchange Commission on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers (other than a filing on a Form 5 made after the expiration of the Lock-Up Period):
 

 
(i)
as a bona fide gift or gifts;
 
(ii)
to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin);
 
(iii)
as a distribution or other transfer by a partnership to its partners or former partners or by a limited liability company to its members or retired members or by a corporation to its stockholders or former stockholders or to any wholly-owned subsidiary of such corporation;
 
(iv)
to the undersigned’s affiliates or to any investment fund or other entity controlled or managed by the undersigned;
 
(v)
pursuant to a qualified domestic relations order or in connection with a divorce settlement;
 
(vi)
by will or intestate succession upon the death of the undersigned; or
 
(vii)
to the Company in satisfaction of any tax withholding obligation.
 
Furthermore, no provision in this letter shall be deemed to restrict or prohibit (1) the transfer of the undersigned’s Lock-Up Securities to the Company in connection with the termination of the undersigned’s services to the Company, provided that any filing under Section 16 of the Exchange Act made in connection with such transfer shall clearly indicate in the footnotes thereto that the filing relates to the circumstances described in this clause (1); (2) the exercise or exchange by the undersigned of any option or warrant to acquire any shares of Common Stock or options to purchase shares of Common Stock, in each case for cash or on a “cashless” or “net exercise” basis, pursuant to any stock option, stock bonus or other stock plan or arrangement; provided, however, that the underlying shares of Common Stock shall continue to be subject to the restrictions on transfer set forth in this letter and that any filing under Section 16 of the Exchange Act made in connection with such exercise or exchange shall clearly indicate in the footnotes thereto that (a) the filing relates to the circumstances described in this clause (2) and (b) no shares were sold by the reporting person; (3) the transfer of Lock-Up Securities upon the completion of a bona fide third-party tender offer, merger, consolidation or other similar transaction made to all holders of the Company’s securities involving a change of control of the Company; provided, however, that in the event that such tender offer, merger, consolidation or other such transaction is not completed, such securities held by the undersigned shall remain subject to the restrictions on transfer set forth in this letter; and (4) sales or transfers of Securities acquired on the open market after the date of the Underwriting Agreement, provided that no such transaction is required to be, or is, publicly announced (whether on Form 4, Form 5 or otherwise) during the Lock-Up Period.
 
Notwithstanding anything herein to the contrary, nothing herein shall prevent the undersigned from establishing a 10b5-1 trading plan that complies with Rule 10b5-1 under the Exchange Act (“10b5-1 Trading Plan”) or from amending an existing 10b5-1 Trading Plan so long as there are no sales of Lock-Up Securities under any such 10b5-1 Trading Plan during the Lock-Up Period; and provided that, the establishment of a 10b5-1 Trading Plan or the amendment of a 10b5-1 Trading Plan shall only be permitted if (i) the establishment or amendment of such plan is not required to be reported in any public report or filing with the Securities Exchange Commission, or otherwise and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding the establishment or amendment of such plan.
 
The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.  This lock-up agreement shall automatically terminate, and the undersigned shall be released from the undersigned’s obligations hereunder, upon the earliest to occur, if any, of (i) prior to the execution of the Underwriting Agreement, the Company advises Leerink in writing that it has determined not to proceed with the Public Offering; (ii) the Underwriting Agreement is executed but is terminated prior to the closing of the Public Offering (other than the provisions thereof which survive termination), or (iii) February 24, 2018, in the event that the Underwriting Agreement has not been executed by such date.
 

 
This agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
