Schedule 13D
PAGE 4 of 7

ITEM 1.
SECURITY AND ISSUER
This statement on Schedule 13D relates to the common stock, par value $0.001 per share (the “Common Stock”), of Xenetic Biosciences, Inc., a Nevada corporation (the “Issuer”). The principal executive offices of the Issuer are located at: 40 Speen Street, Suite 102, Framingham, MA 01701.
ITEM 2.
IDENTITY AND BACKGROUND
Set forth in Schedule 1 to this Schedule 13D are the name, business address and present principal occupation or employment and citizenship of each executive officer and director of OPKO Health, Inc. (the “Reporting Person” or “OPKO”).
(a), (f) This statement is being filed by OPKO, a corporation incorporated under the laws of the State of Delaware.
(b)    The address of the principal business and principal office of OPKO is 4400 Biscayne Blvd., Miami, Florida 33137.
(c)    OPKO is a diversified healthcare company that seeks to establish industry-leading positions in large and rapidly growing medical markets.
(d), (e) Except as described herein, during the last five years, neither the Reporting Persons nor any of the persons listed on Schedule I hereto (i) has been convicted in a 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 violations with respect to such laws.
On September 7, 2018, the Securities and Exchange Commission filed a civil complaint in the Southern District of New York (the “Complaint”), against a number of individuals and entities, including OPKO and its CEO and Chairman, Dr. Phillip Frost and Frost Gamma Investments Trust (“FGIT”), an entity of which Dr. Frost is trustee. In December 2018, OPKO, Dr. Frost and FGIT entered into settlements with the SEC, which, upon approval by the court in January 2019, resolved the claims against OPKO, Dr. Frost and FGIT. Under the terms of the settlement between the SEC, Dr. Frost and FGIT, and without admitting or denying any of the allegations in the Complaint, Dr. Frost agreed to injunctions from violations of Sections 5(a) and (c) and 17(a)(2) of the Securities Act of 1933, claims which may be satisfied by strict liability and negligence, respectively, and Section 13(d) of the Exchange Act, also a strict liability claim; to pay a civil monetary penalty, disgorgement and pre-judgment interest, which have been paid; and to be prohibited, with certain exceptions, from trading in penny stocks. Pursuant to the settlement between OPKO and the SEC, and without admitting or denying any of the allegations of the Complaint, OPKO agreed to be enjoined from future violations of Section 13(d) of the Securities Exchange Act of 1934 (the “Exchange Act”), a claim that requires no showing of scienter, and to pay a civil monetary penalty, which has been paid. OPKO also agreed, within certain stipulated time periods, to: (i) establish a Management Investment Committee (“MIC”) that will make recommendations to an Independent Investment Committee (“IIC”) of OPKO’s board of directors in connection with existing and future strategic minority investments; and (ii) retain an Independent Compliance Consultant (“ICC”) on a time-limited basis to, among other things, advise OPKO on whether filings pursuant to Section 13(d) of the Exchange Act for previous strategic minority investments made at the suggestion of or in tandem with Dr. Frost and his related persons or entities should be made or amended to reflect group membership with Dr. Frost. The ICC has concluded his work. The ICC determined that certain prior investments by OPKO and Dr. Frost with respect to other issuers should have been grouped under Section 13(d) of the Exchange Act and that amended filings under Section 13(d) of the Exchange Act should be made. OPKO and Dr. Frost made the recommended filings on May 9, 2019.
