Item 1.    Security and Issuer
This Schedule relates to the common stock, par value $0.001 (the “Shares”), of Idenix Pharmaceuticals, Inc. (the “Issuer”). The address of the principal executive offices of the Issuer is 320 Bent Street, Cambridge, Massachusetts 02141.
Item 2.    Identity and Background
This Schedule is being filed pursuant to Rule 13d-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by Merck & Co., Inc., a New Jersey corporation (“Parent”), and Imperial Blue Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”, and together with Parent, the “Reporting Persons”). The address of the principal business and the principal office of each of the Reporting Persons is One Merck Drive, P.O. Box 100, Whitehouse Station, NJ 08889-0100.
Parent is a global health care company that delivers innovative health solutions through its prescription medicines, vaccines, biologic therapies, animal health, and consumer care products, which it markets directly and through its joint ventures. Merger Sub has not conducted any business and has no assets, liabilities or obligations of any nature other than those incident to its formation and pursuant to the Merger Agreement (as defined below) and the transactions contemplated thereby.
The name, business address, present principal occupation or employment and citizenship of each director and executive officer (including a director and officer who may be a controlling person) of the Reporting Persons is set forth on Schedule A.
During the last five years, none of the Reporting Persons or, to the knowledge of the Reporting Persons, any of the persons listed on Schedule A have been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been 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
The total amount of funds required by the Reporting Persons to purchase all of the outstanding Shares in the Offer (as defined below) and the Merger (as defined below) is approximately $3.85 billion, plus related fees and expenses. The Reporting Persons currently have available to them in cash on hand all funds necessary for these payments.
Item 4.    Purpose of Transaction
On June 8, 2014, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”), among the Issuer, Parent, and Merger Sub. Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Merger Sub will commence a tender offer (the “Offer”) to purchase all of the issued and outstanding Shares at a price of $24.50 per Share in cash, net to the seller in cash but subject to any applicable withholding of taxes (the “Offer Price”).
The obligation of Parent and Merger Sub to consummate the Offer is subject to the condition that there be validly tendered and not withdrawn prior to the expiration of the Offer a number of Shares representing at least a majority of the outstanding Shares on a fully diluted basis as of the scheduled expiration of the Offer (assuming the issuance of all Shares issuable upon the exercise of all outstanding options and other rights to purchase Shares). The obligation of Merger Sub to consummate the Offer is subject to the expiration of the waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and other customary closing conditions. Consummation of the Offer is not subject to a financing condition. The parties have agreed that the initial expiration date of the Offer will be August 4, 2014.

Following the consummation of the Offer and subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into the Issuer pursuant to the provisions of the General Corporation Law of the State of Delaware (the “DGCL”) as provided in the Merger Agreement, with the Issuer being the surviving corporation (the “Merger”). At the effective time of the Merger (the “Effective Time”), each Share (other than (i) Shares owned by Parent, Merger Sub, the Issuer or any of their respective direct or indirect wholly-owned subsidiaries and (ii) Shares held by stockholders who have properly demanded appraisal of such Shares in accordance with the DGCL) will be cancelled and converted into the right to receive an amount in cash equal to the Offer Price, without interest and subject to any applicable withholding of taxes. The Merger Agreement contemplates that the Merger will be effected pursuant to Section 251(h) of the DGCL, which permits completion of the Merger upon the acquisition by Merger Sub of one share more than 50% of the number of Shares that are then issued and outstanding. If the Merger is effected pursuant to Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. The closing of the Merger is subject to customary closing conditions.
Concurrently with the execution of the Merger Agreement, The Baupost Group, L.L.C. (the “Stockholder”) entered into a support agreement (the “Support Agreement”) with Parent and Merger Sub with respect to 22,477,560 shares owned by the Stockholder (the “Subject Shares”). Pursuant to the terms of the Support Agreement, such Stockholder has agreed to not sell its Subject Shares, to not solicit any acquisition proposals and to vote it Subject Shares against any competing acquisition proposals. The Subject Shares comprise approximately 14.9% of all outstanding Shares. The Support Agreement will terminate in certain circumstances, including upon termination of the Merger Agreement. Shared voting power with respect to the Subject Shares may be deemed to have been acquired through execution of the Support Agreement. The Reporting Persons have not expended any funds in connection with the execution of the Support Agreement.
The purpose of the Offer is to acquire control of, and ultimately following the Merger, the entire equity interest in, the Issuer while allowing the Issuer’s stockholders an opportunity to receive the Offer Price promptly by tendering their Shares into the Offer. After the consummation of the Offer, Parent and Merger Sub intend to consummate the Merger as promptly as practicable, subject to the satisfaction or waiver of certain conditions. At the effective time of the Merger, (i) the certificate of incorporation of the surviving corporation will be amended and restated in its entirety as set forth in an exhibit to the Merger Agreement, (ii) the bylaws of Merger Sub, as in effect immediately prior to the effective time of the Merger, will be the bylaws of the surviving corporation and (iii) the directors and officers of Merger Sub immediately prior to the effective time of the Merger will be the initial directors and officers of the surviving corporation. Following the Merger, the Shares will no longer be traded on the NASDAQ Global Market, there will be no public market for the Shares, and registration of the Shares under the Exchange Act will be terminated. Except as set forth in this Schedule 13D and in connection with the Offer, the Merger and the Support Agreement described above, the Reporting Persons do not have any plan or proposals that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.
The foregoing description of the (i) Merger Agreement and the transactions contemplated thereby and (ii) the Support Agreement and the transactions contemplated thereby, in each case, do not purport to be complete and are qualified in their entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and which is incorporated herein by reference, and to the Support Agreement, which is filed as Exhibit 99.1 hereto and which is incorporated herein by reference.
The Offer has not yet commenced. The foregoing is neither an offer to purchase nor a solicitation of an offer to sell Shares, nor is it a substitute for the tender offer materials that Parent and Merger Sub will file with the Securities and Exchange Commission (“SEC”) upon commencement of the Offer. At the time the Offer is commenced, Parent and Merger Sub will file tender offer materials on Schedule TO, and the Issuer will file a Solicitation/Recommendation Statement on Schedule 14D-9 with the SEC with respect to the Offer. The tender offer materials (including an Offer to Purchase, a related Letter of Transmittal and certain other tender offer documents) and the Solicitation/Recommendation Statement will contain important information. Holders of Shares are urged to read these documents when they become available because they will contain important information that holders of Issuer securities should consider before making any decision regarding tendering their securities. The Offer to Purchase, the related Letter of Transmittal and certain other tender offer documents, as well as the Solicitation/Recommendation Statement, will be made available to all holders of Shares at no expense to them. The tender offer materials and the Solicitation/Recommendation Statement will be made available for free at the SEC’s web site at www.sec.gov.

Item 5.    Interest in Securities of the Issuer
(a), (b).    Other than those Subject Shares that may be deemed to be beneficially owned in connection with the Support Agreement, the Reporting Persons have not acquired and, for the purposes of Rule 13d-4 promulgated under the Exchange Act, do not beneficially own any Shares. As a result of the Support Agreement, the Reporting Persons may be deemed to have the power to vote up to an aggregate of 22,477,560 Shares against certain matters set forth in Item 4 above, and thus, for the purpose of Rule 13d-3 promulgated under the Exchange Act, the Reporting Persons may each be deemed to be the beneficial owner of an aggregate of 22,477,560 Shares. The Subject Shares that may be deemed to be beneficially owned by the Reporting Persons constitute approximately 14.9% of the issued and outstanding Shares as of June 8, 2014 (based on 150,856,104 Shares outstanding as of the close of business on June 8, 2014, as represented by the Issuer in the Merger Agreement). The Reporting Persons are not entitled to any rights as stockholders of the Issuer as to the Subject Shares, except as otherwise expressly provided in the Support Agreement. This Schedule 13D shall not be construed as an admission by the Reporting Persons that the Reporting Persons are, for the purposes of Section 13(d) of the Exchange Act, the beneficial owners of the Subject Shares. Except as set forth herein, none of the Reporting Persons nor, to the knowledge of the Reporting Persons, any of the persons named in Schedule A hereto beneficially own any Shares.
(c)    Except for the Merger Agreement and the Support Agreement, to the knowledge of the Reporting Persons, no transactions in the class of securities reported have been effected during the past 60 days by any person named in Schedule A or Item 5(a).
(d)    To the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities of the Issuer reported herein.
(e)    Not applicable.
Item 6.    Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
Except for the Merger Agreement and the Support Agreement, to the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise), including, but not limited to, transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, among the persons named in Item 2 or between such persons and any other person, with respect to any securities of Issuer, including any securities pledged or otherwise subject to a contingency the occurrence of which would give another person voting power or investment power over such securities other than standard default and similar provisions contained in loan agreements.

2.1
Agreement and Plan of Merger, dated as of June 8, 2014, by and among the Issuer, Parent and Merger Sub (incorporated by reference to Exhibit 2.1 to the Current Report on Form 8-K filed by the Issuer with the SEC on June 9, 2014).
