Pursuant to Rule 13d-2 of the Securities Exchange Act of 1934, this Amendment No. 1 (this “Amendment”) amends and supplements the Schedule 13D filed with the United States Securities and Exchange Commission (the “SEC”) on October 29, 2020 (the “Original 13D” and, together with this Amendment, the “Schedule 13D”), and is being jointly filed by (i) Endo International plc, a public limited company incorporated in Ireland (“Endo”), and (ii) Beta Acquisition Corp., a Delaware corporation (“Merger Sub” and, together with Endo, the “Reporting Persons”).

ITEM 3. Source and Amount of Funds or Other Consideration.

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

“On December 2, 2020, Endo consummated the acquisition of Issuer through the Merger. The aggregate consideration payable in connection with the Shares (as defined in the Original 13D) upon the consummation of the Offer (as defined in the Original 13D) and the Merger was approximately $650 million, which was funded from cash on hand of Endo.

The information set forth or incorporated by reference in Item 4 is incorporated by reference in this Item 3.”

ITEM 4. Purpose of the Transaction.

Item 4 of the Original 13D is hereby amended and supplemented by deleting the last paragraph of Item 4 and replacing it with the following paragraphs:

“Merger Sub commenced the Offer on November 2, 2020. In connection with the Offer, also on November 2, 2020, Endo and Merger Sub filed a tender offer statement on Schedule TO with the SEC, and Issuer filed a solicitation/recommendation statement on Schedule 14D-9 with respect to the Offer. As of one minute after 11:59 PM, New York time, on December 1, 2020, when the Offer expired, approximately 6,159,975 Shares were validly tendered and not validly withdrawn pursuant to the Offer, excluding 365,128 Shares tendered pursuant to guaranteed delivery procedures. On December 2, 2020, Merger Sub accepted for payment, and expects to as soon as practicable pay for, all Shares validly tendered and not validly withdrawn prior to the expiration of the Offer.

On December 2, 2020, Merger Sub merged with and into Issuer pursuant to Section 251(h) of the General Corporation Law of the State of Delaware and without any stockholder vote, with Issuer surviving the Merger as a wholly-owned subsidiary of Endo, pursuant to the Merger Agreement. At the Effective Time, each Share outstanding immediately prior to the Effective Time (other than (a) Shares owned by Endo, Merger Sub, Issuer, or by any of their direct or indirect wholly-owned subsidiaries, in each case at the commencement of the Offer and immediately prior to the Effective Time, (b) Shares irrevocably accepted for purchase pursuant to the Offer or (c) Shares owned by any stockholders who properly and validly demanded their appraisal rights in compliance with Section 262 of the DGCL) were automatically converted into the right to receive the Offer Price, without interest and less any applicable withholding taxes.

4

Effective as of immediately prior to the Effective Time, (i) each outstanding Issuer stock option was automatically canceled and converted into the right to receive an amount in cash, without interest, equal to the product of (A) the number of Shares underlying such option immediately prior to the Effective Time multiplied by (B) the amount, if any, by which the Offer Price exceeds the exercise price per share of such option, and (ii) each outstanding Issuer restricted stock unit (“RSU”) became fully vested (to the extent unvested) and was automatically converted into the right to receive an amount in cash equal to the product of (A) the number of Shares underlying such RSU immediately prior to the Effective Time multiplied by (B) the Offer Price, without interest and subject to any deduction for any withholding taxes.

At the Effective Time, the certificate of incorporation of Issuer was amended and restated in its entirety pursuant to the terms of the Merger Agreement. As of the Effective Time, the bylaws of Issuer were amended and restated in its entirety to be in the form of the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, subject to certain amendments specified in the Merger Agreement.

At the Effective Time, and as a result of the Merger, all outstanding shares of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time were converted into an aggregate of 100 shares of newly and validly issued, fully paid and non-assessable shares of common stock of the Surviving Corporation. Consequently, following the consummation of the Merger on December 2, 2020, Endo became the owner of 100 shares of common stock of the Surviving Corporation, representing the only outstanding capital of the Surviving Corporation.

At the Effective Time, the Support Agreement terminated in accordance with its express terms.

In accordance with the Merger Agreement, at the Effective Time, the directors of Merger Sub, immediately prior to the Effective Time became the initial directors of the Surviving Corporation, and the officers of Merger Sub, immediately prior to the Effective Time, became the initial officers of the Surviving Corporation.

On December 2, 2020, in connection with the Merger, Issuer notified Nasdaq of the consummation of the Merger and requested that trading of the Shares on Nasdaq be suspended prior to the opening of trading on December 2, 2020. In addition, at Issuer’s request, Nasdaq filed with the SEC an application on Form 25 to delist the Shares from Nasdaq and deregister the Shares under Section 12(b) of the Securities and Exchange Act of 1934, as amended (the “Act”). Trading of shares on Nasdaq was suspended prior to the opening of trading on December 2, 2020. Issuer intends to file with the SEC a Form 15 requesting that Issuer’s reporting obligations under Section 13 and Section 15(d) of the Act be suspended.

The information set forth or incorporated by reference in Item 3 is incorporated by reference in this Item 4.”

ITEM 5. Interest in Securities of Issuer.

Item 5 of the Original 13D is hereby amended and restated in its entirety as follows:

“(a), (b)

At the Effective Time, and as a result of the Merger, all outstanding shares of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time were converted into an aggregate of 100 shares of newly and validly issued, fully paid and non-assessable shares of common stock of the Surviving Corporation. Consequently, following the consummation of the Merger on December 2, 2020, Endo became the owner of, and for purposes of Rule 13d-3, beneficially owns, and has the sole power to vote and dispose of, 100 shares of common stock of the Surviving Corporation, representing the only outstanding capital of the Surviving Corporation. In addition, as a result of the Merger, the separate corporate existence of Merger Sub has ceased, and therefore Merger Sub owns no shares of Issuer and has no authority to vote or direct the vote for any shares of Issuer. Except as set forth in this Item 5(a), none of the Reporting Persons and, to the knowledge of the Reporting Persons, no person named in Schedule A, beneficially owns or has any voting power or dispositive power over any Shares.

5

(c)

Other than as described above, since the filing of the Original 13D on October 29, 2020, 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 Issuer reported herein.

(e)

As a result of the termination of its corporate existence in connection with the Merger, Merger Sub ceased to be the beneficial owner of any securities of Issuer.

Given that the registration of the Shares of Issuer will be terminated, Shares held by Endo will no longer be subject to reporting under Section 13(d) of the Exchange Act.

Consequently, this Amendment constitutes an exit filing for the Reporting Persons.”

Item 6 of the Original 13D is hereby amended and supplemented by adding the following at the end thereof:

“At the Effective Time, the Support Agreement terminated in accordance with its express terms.”

Item 7 of the Original 13D is hereby amended and supplemented as follows:
