"NovaQuest") and NQ POF V GP, Ltd. ("NovaQuest GP"), the investment committee of which makes voting and investment decisions regarding securities held by NovaQuest (collectively, the "Reporting Persons").

(b) The business address of the Reporting Persons is 4208 Six Forks Road, Suite 920, Raleigh, North Carolina 27609.

(d) – (e) During the last five years, the Reporting Persons: (i) have not been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors); or (ii) have not been parties to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding 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.

(f) NovaQuest is a Delaware limited partnership and NovaQuest GP is a Cayman Islands limited company.

**Item 3. Source and Amount of Funds or Other Consideration**

The Reporting Persons are filing this Schedule 13D as a result of stockholder approval on certain matters in connection with the Issuer's September 28, 2022 stock-for-stock acquisition (the "Acquisition") of Aceragen, Inc. ("Private Aceragen"), pursuant to the terms of the Agreement and Plan of Merger, dated September 28, 2022, by and among the Issuer, Bell Merger Sub I, Inc., Bell Merger Sub II, LLC and Private Aceragen (the "Merger Agreement").

Under the terms of the Merger Agreement, at the closing of the Acquisition, the Issuer issued to the former stockholders of Private Aceragen shares of Common Stock and shares of its Series Z Non-Voting Convertible Preferred Stock, par value $0.01 per share (the "Series Z Preferred Stock"), which was a newly designated convertible series of preferred stock, each share of which was convertible into 1,000 shares of Common Stock. Additionally, under the terms of the Merger Agreement, all issued and outstanding warrants to purchase shares of Private Aceragen's capital stock were assumed by the Issuer and converted into warrants to purchase shares of Common Stock and Series Z Preferred Stock on substantively the same terms and conditions that applied to such warrants immediately prior to the Acquisition. Pursuant to the Merger Agreement, and in exchange for the outstanding Private Aceragen warrants held by NovaQuest, NovaQuest received a warrant to purchase (i) 1,343,547 shares of Common Stock and (ii) 14,115 shares of Series Z Preferred Stock.

The Issuer held a Special Meeting of stockholders on January 12, 2023, where the conversion of Series Z Preferred Stock into shares of Common Stock in accordance with Nasdaq Listing Rule 5635(a) (the "Conversion Proposal") was approved so that each share of Series Z Preferred Stock was to be converted into 1,000 shares of Common Stock on January 17, 2023.

In connection with the Acquisition, the Reporting Persons also received five shares of Issuer non-voting, non-convertible Series X Preferred Stock in exchange for five shares of Private Aceragen Series X Preferred Stock.

For more information on the Merger Agreement, see Exhibit 2.1 to the Issuer's Current Report on Form 8-K filed with the SEC on September 30, 2022, which is incorporated herein by reference. For more information on the Conversion Proposal see the Issuer's Definitive Proxy Statement on Schedule 14A as filed with the SEC on December 8, 2022.

On January 17, 2023, the Issuer announced a 1-for-17 reverse stock split of its Common Stock, effective January 17, 2023, and that it changed its name from Idera Pharmaceuticals, Inc. (Nasdaq: IDRA) to Aceragen, Inc. (Nasdaq: ACGN).

**Item 4. Purpose of Transaction.**

As adjusted for the reverse stock split, the Reporting Persons obtained beneficial ownership of 830,294 shares of Common Stock underlying a warrant, pursuant to the approval of the Conversion Proposal on January 12, 2023, which conversion was effective on January 17, 2023, as described in Item 3, in addition to the 79,032 shares of Common Stock underlying a warrant that the Reporting Persons beneficially owned following the Acquisition. The Reporting Persons do not have any present plans or proposals that relate to or would result in: (i) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (ii) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of the Issuer's subsidiaries; (iii) a sale or transfer of a material amount of assets of the Issuer or any of the Issuer's subsidiaries; (iv) any change in the present board of directors or management of the Issuer; (v) any material change in the present capitalization or dividend policy of the Issuer; (vi) any other material change in the Issuer's business or corporate structure; (vii) changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (viii) causing a class of securities of the Issuer to be 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; (ix) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (x) any action similar to any of those enumerated above.

**Item 5. Interest in Securities of the Issuer.**

(a) See rows (11) and (13) of the cover pages to this Schedule 13D for the aggregate number of Shares and percentage of the Shares beneficially owned by the Reporting Persons. The percentage used in this Schedule 13D are calculated based upon 8,461,063 shares of Issuer's Common Stock outstanding as of January 17, 2023, as reported in the Issuer's Form 8-K.

(b) See rows (7) through (10) of the cover pages to this Schedule 13D for the number of Shares as to which the Reporting Persons have the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.

(c) Reference is made to the discussion in Item 3. Each of the required transactions described in this Item 5(a) were reported on Forms 3 and 4 filed with the SEC pursuant to Section 16 of the Act and is available on the SEC's website at <u>www.sec.gov</u>. The information reported in the filing is expressly incorporated herein.
