SCHEDULE 13D

 

This Amendment No. 3 to the Schedule 13D (“Schedule 13D/A”), which amends the statement on Schedule 13D dated June 22, 2021, as further amended on August 24, 2021 and August 12, 2022 (“Schedule 13D”), is filed with the SEC by the Reporting Person. Except as expressly amended below, the Schedule 13D remains in effect. Capitalized terms used but not defined in this Schedule 13D/A shall have the meanings set forth in the Schedule 13D.

 

This Schedule 13D/A is being filed to show the Reporting Person’s beneficial ownership further to increases in the number of issued and outstanding shares of the Issuer’s Common Stock. In addition, on January 4, 2023, the Issuer effected a one-for-twenty (1:20) reverse stock split, whereby every twenty shares of the Issuer’s Common Stock was automatically converted into one share of the Issuer’s Common Stock.

 

Item 1. Security and Issuer

 

This Schedule 13D/A relates to the Issuer’s Common Stock. The principal executive offices of the Issuer are located at 101 Glen Lennox Drive, Suite 300, Chapel Hill, North Carolina 27517.

 

Item 4. Purpose of Transaction

 

Dr. Doogan has acquired, and holds, the shares of Common Stock reported herein for investment purposes. He may acquire additional shares of Common Stock depending on market conditions and the business performance of the Issuer, but does not currently plan to purchase a number of additional shares of Common Stock that would result in a substantial change in his beneficial ownership or his ability to influence control of the Issuer.

 

Other than as described above, and except that Dr. Doogan may, from time to time or at any time, subject to market conditions and other factors, purchase additional shares of Common Stock in the open market, in privately negotiated transactions or otherwise, sell at any time all or a portion of the shares of Common Stock now owned or hereafter acquired by him to one or more purchasers, or transfer or contribute shares of Common Stock to trusts for estate planning purposes, Dr. Doogan does not have any present plans which relate to or would result in any of the matters referred to in paragraphs (a) through (j) of Item 4 of Schedule 13D.

 

Item 5. Interest in Securities of the Issuer

 

(a) See rows (11) and (13) of the cover pages to this Schedule 13D/A for the aggregate number of shares of Common Stock and percentage of shares of Common Stock beneficially owned by the Reporting Person.

 

(b) See rows (7) through (10) of the cover pages to this Schedule 13D/A for the number of shares of Common Stock as to which the Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.
