Redmile Group, LLC and Mr. Green each disclaim beneficial ownership of the stock option, except to the extent of its or his pecuniary interest in the shares subject to such option, if any, and this Schedule 13D shall not be deemed an admission that the Reporting Persons are the beneficial owner of such securities any purpose.

Item 3 of the Schedule 13D is hereby amended and restated to read in its entirety as follows:

The source of funds was working capital of the entities for which Redmile Group, LLC is the investment manager/adviser listed in items (i) through (ix) of Item 5(a) below.

Lundbeck A/S, a Danish aktieselskab (the “Parent”), LundBeck LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of Parent (the “Payor”), and Violet Acquisition Corp., a Delaware corporation and a direct wholly owned subsidiary of Payor (the “Purchaser”). Pursuant to the Merger Agreement, upon the terms and subject to the conditions thereof the Purchaser will commence a tender offer no later than September 30, 2019 to acquire all of the outstanding shares of Common Stock at an offer price of (i) $18.00 per share, net to the seller in cash, without interest, plus (ii) one (1) contingent value right per share which represents the right to receive $2.00 per CVR, net to the seller in cash, without interest, at the time provided in the Contingent Value Rights Agreement in the form attached as Annex II to the Merger Agreement, and subject to any withholding of taxes (the “Tender Offer”). As soon as practicable following the acceptance of shares of Common Stock pursuant to the Tender Offer and upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with Section 251(h) of the General Corporation Law of the State of Delaware, the Purchaser will merge with and into the Issuer, with the Issuer surviving as a wholly owned subsidiary of the Parent (the “Merger”), without a meeting or vote of stockholders of the Issuer.

Pursuant to the Tender and Support Agreement, the Reporting Persons agreed, among other things, to tender their shares of Common Stock pursuant to the Tender Offer and, if necessary, vote their shares of Common Stock (i) for the adoption of the Merger Agreement if required; (ii) against any action or agreement that is intended or would reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Issuer contained in the Merger Agreement, or of any tendering stockholder contained in the Tender and Support Agreement, or would result in any of the conditions to the Tender Offer or the Merger not being timely satisfied; (iii) against any change in the board of directors of the Issuer; (iv) against any Acquisition Proposal (as defined in the Merger Agreement); (v) against any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving the Issuer (other than the Merger); (vi) against any sale, lease, license or transfer of a material amount of the business or assets, or any reorganization, recapitalization or liquidation, of the Issuer and its subsidiaries; (vii) against any change in the present authorized capitalization of the Issuer or any amendment or other change to the Issuer’s certificate of incorporation, bylaws and any other charter and organizational documents, including any amendment that would authorize any additional shares or classes of shares of capital stock or change in any manner the rights and privileges, including voting rights, of any class of the Issuer’s capital stock; and (viii) against any other plan, proposal, arrangement, action, agreement or transaction involving the Issuer or its subsidiaries that is intended, or would reasonably be expected, to impede, interfere with, delay, postpone, adversely affect or prevent the consummation of the Tender Offer, the Merger or the other transactions contemplated by the Merger Agreement. The Tender and Support Agreement terminates in the event that the Merger Agreement is terminated.
