Sundheim, a citizen of the United States (each, a “Reporting Person”, and, collectively, the “Reporting Persons”).

The Reporting Persons have entered into a joint filing agreement, dated as of July 13, 2016, a copy of which is filed herewith as Exhibit 99.1.

(b) The business address of each of the Reporting Persons is 55 Railroad Avenue, Greenwich, Connecticut 06830.

The principal business of each of the Funds is to engage in making investments in securities of public and private companies.

(d), (e) During the last five years, none of the Reporting Persons (i) has been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was 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 Reporting Persons do not directly own any Common Shares. The Reporting Persons acquired Roivant Sciences Ltd. (“Roivant”) common shares (the “Roivant Common Shares”) on December 8, 2015 pursuant to share purchase agreements using capital invested in the Funds by their investors. Roivant directly holds the 75,000,000 Common Shares reported herein. The Issuer, prior to its initial public offering on June 11, 2015, was a wholly-owned subsidiary of Roivant.

No part of the purchase price was borrowed by any Reporting Person for the purpose of acquiring any securities discussed in this Item 3.

The information set forth or incorporated in Items 4 and 5 is hereby incorporated herein by reference.

Item 4.  Purpose of Transaction

The Reporting Persons do not directly own any Common Shares. In addition, the Reporting Persons currently have no plans or proposals, whether effectuated directly or through the Reporting Persons’ relationship with Roivant, that involve the Issuer and that relate to the management of the Issuer, or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D (“13D Transactions”).

Effective July 8, 2016, Dr. Andrew Lo was appointed to the board of directors of Roivant (the “Board”). Dr. Lo is an “independent director” within the meaning of that term under Roivant’s bye-laws. As of the appointment of the independent director, the Reporting Persons voting unanimously with two other major shareholders of Roivant have the right to override certain decisions of the Board under Roivant’s bye-laws, including with respect to dispositions of Common Shares (the “Override Right”). Roivant directly owns the Common Shares that are the subject of this Schedule 13D. As shareholders of Roivant, the Reporting Persons are filing this Schedule 13D because they may be accordingly deemed to have “dispositive power” and, therefore, beneficial ownership, over the Common Shares owned directly by Roivant due to the Override Right.

The filing of this statement shall not be deemed an admission that the Reporting Persons are, for the purposes of Section 13 of the Securities Exchange Act of 1934, as amended, the beneficial owners of any securities covered by this statement. The Reporting Persons may from time to time consider pursuing or proposing 13D Transactions and may discuss, evaluate and/or pursue any such 13D Transactions with their advisors, the Issuer or other persons.

Item 5.  Interest in Securities of the Issuer

(a)-(b) The information contained on each of the cover pages of this Schedule 13D and the information set forth or incorporated in Items 2, 3, 4 and 6 are hereby incorporated herein by reference.

The Reporting Persons do not directly own any Common Shares. As described in Item 4 above, the Reporting Persons may be deemed to beneficially own the Common Shares owned directly by Roivant as a result of the Override Right. The aggregate number and percentage of Common Shares owned directly by Roivant (and which may be deemed to be beneficially owned by each Reporting Person) are, as of the date hereof: 75,000,000 Common Shares, representing 75.6% of the issued and outstanding Common Shares of the Issuer.

(a Cayman Islands exempted company), through its investment in Viking Long Fund Intermediate LP (a Cayman Islands limited partnership), invest substantially all of their assets through VLFM.

VGI provides managerial services to the Funds. VGI has the power to direct the vote and disposition of investments held by the Funds. Accordingly, VGI may be deemed to have beneficial ownership over any Common Shares deemed beneficially owned by the Funds.

VGP, as the general partner of VGE and VGEII, has the power to direct the vote and disposition of investments held by VGE and VGEII. Accordingly, VGP may be deemed to have beneficial ownership over the Common Shares beneficially owned by VGE and VGEII.
