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

Item 3 is hereby amended and supplemented as follows:

On December 14, 2017, the Issuer entered into a binding Memorandum of Understanding (the “MOU”) with Bin Zhao, pursuant to which the Issuer was bound to issue to the Reporting Persons in a private placement (the “Private Placement”) shares of its common stock at a purchase price of $2.00 per share or, to the extent the Reporting Persons, following the transaction, would collectively own more than 49.99% of the Issuer’s common stock, shares of Series D Convertible Preferred Stock of the Issuer (the “Preferred Stock”) with a per-share purchase price of $1,000. Additionally, in accordance with the binding MOU, the Reporting Persons would receive warrants to purchase shares of the Issuer’s common stock (or, to the extent the Reporting Persons would own more than 49.99% of the Issuer’s common stock, shares of Preferred Stock).

To further evidence the binding obligations of the MOU and effectuate the Private Placement thereunder, the Issuer entered into a Securities Purchase Agreement effective as of December 27, 2017 (the “Purchase Agreement”) with the Reporting Persons, and closed the Private Placement simultaneously with the effectiveness of the Purchase Agreement. In accordance with the MOU and the Purchase Agreement, the Issuer issued to the Reporting Persons (i) 518,000 shares (the “Common Shares”) of the Issuer’s common stock, par value $0.01 per share (the “Common Stock”), (ii) 3,108 shares of Series D Convertible Preferred Stock (the “Series D Preferred Stock”), and (ii) warrants to purchase 3,108,000 shares of Common Stock (the “Warrants”), of which Bin Zhao concurrently assigned warrants to purchase 540,000 shares of Common Stock to persons who are not Reporting Persons or parties to the Purchase Agreement.

The Warrants have an exercise price of $2.00 per share, subject to adjustments as provided under the terms of the Warrants, and are immediately exercisable. The Warrants are exercisable for five years from the issuance date.

The Preferred Stock ranked on parity to the Common Stock, and was entitled to vote on any matters to which shares of the Common Stock are entitled to vote, on an as-if-converted basis. The Preferred Stock included an ownership limitation that limits the Reporting Persons and their affiliates to owning no more than 49.99% of the Common Stock.

In connection with the Private Placement, the Issuer agreed to grant board representation and nomination rights to the Reporting Persons and their affiliates, such that the director nominees of the Reporting Persons shall constitute a majority of the Issuer’s board of directors, but no more than is necessary to constitute such a majority. Pursuant to such representation and nomination rights, Jing Chen, James Shmerling and Wei Zhang were appointed to the Issuer’s board of directors.

The working capital of DST Capital LLC and Polyvia LLC and the personal funds of Jing Chen and Jiong Shao was the source of the funds for the purchase of the Common Stock, Preferred Stock and Warrants. No part of the purchase price of the securities was represented by funds or other consideration borrowed or otherwise obtained for the purpose of acquiring, holding, trading, or voting the securities.

On June 29, 2018, the Reporting Persons elected to convert all of the outstanding shares of Series D Preferred Stock beneficially owned by the Reporting Persons into an aggregate of 1,554,000 shares of Common Stock.

Item 4. Purpose of Transaction.

Item 4 is hereby amended and supplemented as follows:

Pursuant to the Private Placement described in Item 3 above, the Reporting Persons acquired a majority of the voting power of the Issuer, and have nominated a majority of the members of the Issuer’s board of directors. The Reporting Persons, together with the Issuer, intend to establish a Chinese subsidiary of the Issuer to potentially access the Chinese market for the Issuer’s product candidates. The Reporting Persons acquired the securities for strategic investment purposes. Depending on market conditions, their continuing evaluation of the business and prospects of the Issuer and other factors, the Reporting Persons may dispose of or acquire additional shares of the Issuer.

Except as set forth above, none of the Reporting Persons has any present plans which relate to or would result in:

(a)

The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer;

Item 5 is hereby amended and supplemented as follows:
