Schedule 13D
 
Item 1.
Security and Issuer.
 
This Amendment No. 1 (the “Amendment”) to the statement on Schedule 13D amends the Schedule 13D filed with the SEC on March 27, 2017 (the “Original Schedule 13D”) and relates to the common stock, par value $0.0001 per share (the “Common Stock”), of Aerpio Pharmaceuticals, Inc., a Delaware corporation (the “Issuer”).  The address of the Issuer’s principal executive office is 9987 Carver Road, Cincinnati, OH 45242.
 
On June 26, 2018, the Issuer filed a Prospectus Supplement with the Securities and Exchange Commission (the “SEC”) pursuant to SEC Rule 424(b)(5), in which it reported that it anticipated having 38,834,099 shares of Common Stock outstanding (which assumes no exercise of the underwriters’ option to purchase additional shares) following completion of the offering, which closed on June 28, 2018. As a result of the reported increase in the number of shares of Common Stock outstanding, the percentage of outstanding shares of Common Stock that the Reporting Persons may be deemed to beneficially own was reduced by more than one percent of the Issuer’s shares of Common Stock outstanding since the filing of the Original Schedule 13D.
 
Except as otherwise described herein, the information contained in the Original Schedule 13D remains in effect. Capitalized terms used but not defined in this Amendment shall have the respective meanings set forth with respect thereto in the Original Schedule 13D.
