`
`
`
`complaint against defendants, alleges upon personal knowledge with respect to himself, and upon
`
`information and belief based upon, inter alia, the investigation of counsel as to all other allegations
`
`herein, as follows:
`
`NATURE OF THE ACTION
`
`1.
`
`Plaintiff brings this action against Aerpio Pharmaceuticals, Inc. (“Aerpio” or the
`
`“Company”) and the members of Aerpio’s Board of Directors (the “Board” or the “Individual
`
`Defendants”) for their violations of Sections 14(a) and 20(a) of the Securities Exchange Act of
`
`1934 (the “Exchange Act”), 15 U.S.C. §§ 78n(a), 78t(a), and U.S. Securities and Exchange
`
`Commission (“SEC”) Rule 14a-9, 17 C.F.R. § 240.14a-9. By the action, Plaintiff seeks to enjoin
`
`the vote on a proposed transaction, pursuant to which Aerpio will merge with Aadi Bioscience,
`
`Inc. (“Aadi”) through Aerpio’s subsidiary Aspen Merger Subsidiary, Inc. (“Merger Subsidiary”)
`
`(the “Proposed Transaction”).1
`
`
`1 Non-party Aadi is a clinical-stage biopharmaceutical company focused on precision therapies for
`genetically defined cancers with alterations in mTOR pathway genes. Aadi’s lead drug candidate,
`
`
`
`
`Case 1:21-cv-01123-UNA Document 1 Filed 08/02/21 Page 2 of 12 PageID #: 2
`
`2.
`
`On May 17, 2021, Aerpio and Aadi jointly announced their entry into an Agreement
`
`and Plan of Merger dated May 16, 2021 (the “Merger Agreement”). Under the terms of the
`
`Merger Agreement, each share of Aadi common stock will be converted into the right to receive
`
`approximately 4.9152 shares of Aerpio’s common stock (the “Merger Consideration”).
`
`3.
`
`On July 8, 2021, Aerpio filed a Schedule 14A Definitive Proxy Statement (the
`
`“Proxy Statement”) with the SEC. The Proxy Statement, which recommends that Aerpio
`
`stockholders vote in favor of the Proposed Transaction, omits or misrepresents material
`
`information necessary and essential to that decision. The failure to adequately disclose such
`
`material information constitutes a violation of Sections 14(a) and 20(a) of the Exchange Act as
`
`Aerpio stockholders need such information in order to make a fully informed decision whether to
`
`vote in favor of the Proposed Transaction.
`
`4.
`
`It is imperative that the material information omitted from the Proxy Statement is
`
`disclosed to the Company’s stockholders prior to the forthcoming stockholder vote so that they
`
`can properly exercise their corporate suffrage rights.
`
`5.
`
`For these reasons and as set forth in detail herein, Plaintiff seeks to enjoin
`
`Defendants from taking any steps to consummate the Proposed Transaction unless and until the
`
`material information discussed below is disclosed to the Company’s stockholders or, in the event
`
`the Proposed Transaction is consummated.
`
`
`
`
`ABI-009 (FYARROTM, nab-sirolimus), is a form of sirolimus bound to albumin. Sirolimus is a
`potent inhibitor of the mTOR biological pathway and inhibits downstream signaling from mTOR,
`that can promote tumor growth. Aadi is evaluating ABI-009 in cancers with known mTOR
`pathway activation, including tumor agnostic indications targeting specific genomic alterations
`that activate the mTOR pathway. Non-party Merger Sub is a Delaware corporation and wholly-
`owned subsidiary of Aerpio.

`
`JURISDICTION AND VENUE

`Section 27 of the Exchange Act, 15 U.S.C. § 78aa, and 28 U.S.C. § 1331 (federal question

`SUBSTANTIVE ALLEGATIONS
`
`18.
`
`On May 17, 2021 , Aerpio and Aadi jointly announced in relevant part:
`
`CINCINNATI and PACIFIC PALISADES, Calif, May 17, 2021 (GLOBE
`NEWSWIRE -— Aerpio Pharmaceuticals, Inc. (“Aerpio”) (Nasdaq: ARPO), a
`biopharmaceutical company focused on developing compounds that activate Tie2,
`and Aadi Bioscience, Inc. (“Aadi”), a privately-held biopharmaceutical company
`focusing on precision therapies for genetically-defined cancers with alterations in
`mTOR pathway genes, announced their entry into a definitive merger agreement.
`Following the proposed merger, Aerpio will change its name to “Aadi Bioscience,
`Inc.” and the combined public company will focus on advancing Aadi’s lead
`product candidate, FYARROTM (sirolimus albumin—bound nanoparticles for
`injectable suspension; nab-sirolimus; ABI-009).
`
`In support of the merger, Aerpio has entered into subscription agreements to raise
`$155 million in a Private Investment in Public Equity (PIPE) financing led by Acuta
`Capital Partners and KVP Capital and including Avoro Capital Advisors; Avoro
`Ventures; Venrock Healthcare Capital Partners; BVF Partners, LP; Vivo Capital;
`Alta Bioequities, L.P.; Rock Springs Capital; RTW Investments, LP; Acorn
`Bioventures; and Serrado Capital LLC as well as other undisclosed institutional
`investors.

`Case 1:21-cv-01123-UNA Document 1 Filed 08/02/21 Page 5 of 12 PageID #: 5
`
`The PIPE financing is expected to be consummated concurrently with the closing
`of the merger. Proceeds from the PIPE financing are intended to be used for
`commercialization of FYARRO in advanced malignant PEComa and a planned
`tumor-agnostic registrational trial in solid tumors harboring inactivating alterations
`in the mTOR pathway genes TSC l and TSC2 expected to be initiated by the end of
`2021. Aadi’s first indication, advanced malignant PEComa,
`is an ultra-rare
`sarcoma enriched in TSCl and TSC2 alterations. Aadi has received Orphan
`designation, Fast Track designation and Breakthrough Therapy designation from
`the FDA for FYARRO for the treatment of patients with advanced malignant
`PEComa. Together with the cash expected from both companies at closing, the net
`proceeds of the PIPE financing are expected to fund the company into 2024,
`enabling potential approval and commercial
`launch in PEComa as well as
`completion of a registrational trial in tumors harboring TSC 1 or TSC2 inactivating
`alterations.
`
`Caley Castelein, a board member of Aerpio and the proposed chairman of the
`combined company stated, “Aerpio’s board of directors diligently undertook a
`comprehensive strategic review and has concluded that the proposed transaction
`with Aadi is in the best interest of our shareholders. We believe Aadi’s late-stage
`development program may offer significant medical benefit to PEComa patients
`and important potential for patients with tumors harboring TSCl or TSC2
`inactivating alterations.”
`
`Dr. Neil Desai, founder and chief executive officer of Aadi, added, “FYARRO met
`
`its safety and efficacy endpoints in our study in patients with advanced malignant
`PEComa2 and this finding supports our approach of targeting mTOR pathway
`altered cancers with FYARRO. We are excited about the next chapter of growth
`for Aadi, thankful for the support of our investors, and are energized to continue to
`develop important new treatment options for our patients.”
`
`Anupam Dalal, chief investment officer ofAcuta Capital Partners stated, “Together
`with a group of renowned institutional investors, we are excited to partner with
`Aadi as it advances FYARRO and strives to unlock the potential of mTOR as a
`therapeutic targe .”
`
`Upon closing of the transaction, the combined company will be led by Aadi’s chief
`executive officer, Neil Desai, and headquartered in Los Angeles, California. Aadi’s
`board members Neil Desai and Richard Maroun; Aadi’s board observer Karin
`
`Hehenberger; and current Aerpio board members Anupam Dalal and Caley
`Castelein will be members of the board of directors of the combined company. In
`addition, Behzad Aghazadeh, managing partner of Avoro Capital Advisors and
`Avoro Ventures, will also join the board of the combined company upon the closing
`of the transaction.

`
`Under the terms of the merger agreement, shareholders of Aadi will receive shares
`of newly issued Aerpio common stock. On a pro forma basis, shareholders of Aadi
`will own approximately 66.8% and shareholders of Aerpio will own approximately
`33.2% of the combined company upon the closing of the merger, prior to the
`additional PIPE financing transaction. Following the closing of the concurrent
`PIPE financing, Aerpio shareholders will own approximately 14.7% of the
`combined company. The actual allocation is subject to adjustment based on
`Aerpio’s cash balance at the time of closing.
`
`The terms of the merger agreement contemplate that a non-transferable contingent
`value right (a “CVR”) will be distributed to Aerpio shareholders as of immediately
`prior to the effective time of the merger, entitling CVR holders to receive net
`proceeds received by Aerpio, if any, associated with Aerpio’s legacy assets. The
`terms and conditions of the CVRs will be pursuant to a CVR Agreement Aerpio
`will enter into prior to the closing of the merger (the “CVR Agreement”).
`
`The merger agreement has been approved by the boards of directors of both
`companies. The transaction is expected to close in the third quarter of 202 l , subject
`to approval by Aerpio’s shareholders, the completion of the PIPE financing, and
`customary closing conditions.
`The PIPE financing is expected to close
`concurrently with, and is conditioned upon, the closing of the merger.
`
`Additional information about the transaction will be provided in a Current Report
`on Form 8-K that will be filed by Aerpio with the Securities and Exchange
`Commission (“SEC”) and will be available at www.sec.gov.
`
`Ladenburg Thalmann & Co. Inc. is acting as financial advisor to Aerpio for the
`transaction and Goodwin Procter LLP is serving as its legal counsel. Perella
`Weinberg Partners LP and Ladenburg & Co. are acting as financial advisors to Aadi
`for the transaction and Wilson Sonsini Goodrich & Rosati, RC. is serving as legal
`counsel to Aadi. Jefferies LLC; Cowen and Company, LLC; and Ladenburg & Co.
`are acting as placement agents for the PIPE financing.
`
`The Frog Statement Contains Material Misstatements and Omissions
`
`19.
`
`The defendants filed a materially incomplete and misleading Proxy Statement with
`
`the SEC and disseminated it to Aerpio’s stockholders. The Proxy Statement misrepresents or omits
`
`material information that is necessary for the Company’s stockholders to make an informed
`
`decision whether to vote their shares in favor of the Proposed Transaction.
`
`
`
`Case 1:21-cv-01123-UNA Document 1 Filed 08/02/21 Page 7 of 12 PageID #: 7
`
`20.
`
`Specifically, as set forth below, the Proxy Statement fails to provide Company
`
`stockholders with material information or provides them with materially misleading information
`
`concerning: (a) certain financial projections, relied upon by the Company’s financial advisor
`
`Ladenburg Thalmann & Co. Inc. (“Ladenburg”) in its financial analyses; (b) the data and inputs
`
`underlying the financial valuation analyses that support the fairness opinion provided by
`
`Ladenburg; and (c) information concerning a second, unidentified financial advisor that assisted
`
`the Company in connection with the process leading to the Proposed Transaction.
`
`Material Omissions Concerning the Company’s Financial Projections and Ladenburg’s
`Financial Analyses
`
`21.
`
`The Proxy Statement fails entirely disclose the Company’s financial projections.
`
`In addition, the Proxy Statement fails to disclose the line items underlying the unlevered free cash
`
`flows for Aadi, as well as the assumptions that went into deriving those forecasts.
`
`22.
`
`The Proxy Statement also describes Ladenburg’s fairness opinion and the various
`
`valuation analyses performed in support of their opinions. However, the description of
`
`Ladenburg’s fairness opinion and analysis fails to include key inputs and assumptions underlying
`
`these analyses. Without this information, as described below, Aerpio’s public stockholders are
`
`unable to fully understand these analyses and, thus, are unable to determine what weight, if any,
`
`to place on Ladenburg’s fairness opinions in determining whether to vote in favor of the Proposed
`
`Transaction. This omitted information, if disclosed, would significantly alter the total mix of
`
`information available to Aerpio’s stockholders.
`
`23.
`
`The Proxy Statement fails
`
`to disclosed material
`
`information concerning
`
`Ladenburg’s Discounted Cash Flow Analysis. Specifically, the Proxy fails to disclose: (a) the line
`
`items used to calculate Aadi’s unlevered free cash flows; (b) the assumptions underlying the
`
`adjustments made to the projections utilized in the analysis, (c) the inputs and assumptions
`
`7
`
`
`
`Case 1:21-cv-01123-UNA Document 1 Filed 08/02/21 Page 8 of 12 PageID #: 8
`
`underlying the discount rates ranging from 12.9% to 16.9%; and (iv) the inputs and assumptions
`
`used to conclude that Aadi had no terminal value for purposes of the analysis.
`
`24.
`
`The Proxy Statement fails to disclose material information concerning
`
`Ladenburg’s Analysis of Selected Publicly Traded Companies. Specifically, the Proxy Statement
`
`fails to disclose the individual multiples and metrics that Ladenburg observed for the companies utilized
`
`in the analysis.
`
`25.
`
`The Proxy Statement fails to disclose material information concerning
`
`Ladenburg’s Analysis of Selected Precedent M&A Transactions. Specifically, the Proxy
`
`Statement fails to disclose: (a) the dates on which each of the selected transactions observed
`
`closed; and (b) the inputs and assumptions used to determine the enterprise value for the
`
`transactions observed.
`
`26.
`
`The Proxy Statement also references the fact that the Company retained a
`
`“second financial advisor” in connection with the Proposed Transaction. The Proxy Statement
`
`not only fails to disclose the identity of this advisor, but also the outcome of any financial analyses
`
`performed thereby, and any remuneration paid thereto, as well as any past or current services
`
`(and the amount of remuneration) this advisor is providing to any of the parties to the Proposed
`
`Transaction.2
`
`27.
`
`The omission of this information renders the statements in the “Certain Aerpio
`
`Management Unaudited Prospective Financial Information” and Opinion of Aerpio’s Financial
`
`Advisor” sections of the Proxy Statement false and/or materially misleading in contravention of
`
`
`2 Full disclosure of investment banker compensation and all potential conflicts is required due to
`the central role played by investment banks in the evaluation, exploration, selection, and
`implementation of strategic alternatives.

`
`the Exchange Act.
`
`28.
`
`The Individual Defendants were aware of their duty to disclose the above-
`
`referenced omitted information and acted negligently (if not deliberately) in failing to include
`
`this information in the Proxy Statement. Absent disclosure of the foregoing material information
`
`prior to the stockholder vote on the Proposed Transaction, Plaintiff and the other stockholders of
`
`Aerpio will be unable to make a sufficiently informed voting decision in connection with the
`
`Proposed Transaction and are thus threatened with irreparable harm warranting the injunctive
`
`relief sought herein.
`
`CLAIMS FOR RELIEF
`
`COUNT I
`
`Claims Against All Defendants for Violations of Section 14(a) of the
`Exchange Act and Rule 14a-9 Promulgated Thereunder
`
`Plaintiff repeats all previous allegations as if set forth in full.
`
`During the relevant period, defendants disseminated the false and misleading Proxy
`
`29.
`
`30.
`
`Statement specified above, which failed to disclose material facts necessary to make the
`
`statements, in light of the circumstances under which they were made, not misleading in violation
`
`of Section 14(a) of the Exchange Act and SEC Rule 14a-9 promulgated thereunder.
`
`31.
`
`By virtue of their positions within the Company, the defendants were aware of this
`
`information and of their duty to disclose this information in the Proxy Statement. The Proxy
`
`Statement was prepared, reviewed, and/or disseminated by the defendants. It misrepresented
`
`and/or omitted material facts, including material information about (a) certain financial
`
`projections, (b) the inputs and assumptions underlying Ladenburg’s financial analyses; and (c)
`
`critical information concerning the Company’s “second financial advisor.” The defendants were
`
`9
`
`
`
`Case 1:21-cv-01123-UNA Document 1 Filed 08/02/21 Page 10 of 12 PageID #: 10
`
`at least negligent in filing the Proxy Statement with these materially false and misleading
`
`statements.
`
`32.
`
`The omissions and false and misleading statements in the Proxy Statement are
`
`material in that a reasonable stockholder would consider them important in deciding how to vote
`
`on the Proposed Transaction.
`
`33.
`
`By reason of the foregoing, the defendants have violated Section 14(a) of the
`
`Exchange Act and SEC Rule 14a-9(a) promulgated thereunder.
`
`34.
`
`Because of the false and misleading statements in the Proxy Statement, Plaintiff is
`
`threatened with irreparable harm, rendering money damages inadequate. Therefore, injunctive
`
`relief is appropriate to ensure defendants’ misconduct is corrected.
`
`COUNT II
`
`Claims Against the Individual Defendants for Violations
`of Section 20(a) of the Exchange Act
`
`Plaintiff repeats all previous allegations as if set forth in full.
`
`The Individual Defendants acted as controlling persons of Aerpio within the
`
`35.
`
`36.
`
`meaning of Section 20(a) of the Exchange Act as alleged herein. By virtue of their positions as
`
`officers and/or directors of Aerpio, and participation in and/or awareness of the Company’s
`
`operations and/or intimate knowledge of the false statements contained in the Proxy Statement
`
`filed with the SEC, they had the power to influence and control and did influence and control,
`
`directly or indirectly, the decision-making of the Company, including the content and
`
`dissemination of the various statements which Plaintiff contends are false and misleading.
`
`37.
`
`Each of the Individual Defendants was provided with or had unlimited access to
`
`copies of the Proxy Statement and other statements alleged by Plaintiff to be misleading prior to
`
`10
`
`
`
`Case 1:21-cv-01123-UNA Document 1 Filed 08/02/21 Page 11 of 12 PageID #: 11
`
`and/or shortly after these statements were issued and had the ability to prevent the issuance of the
`
`statements or cause the statements to be corrected.
`
`38.
`
`In particular, each of the Individual Defendants had direct and supervisory
`
`involvement in the day-to-day operations of the Company, and, therefore, is presumed to have had
`
`the power to control or influence the particular transactions giving rise to the securities violations
`
`as alleged herein, and exercised the same. The Proxy Statement at issue contains the unanimous
`
`recommendation of each of the Individual Defendants to approve the Proposed Transaction. They
`
`were, thus, directly involved in the making of the Proxy Statement.
`
`39.
`
`In addition, as the Proxy Statement sets forth at length, and as described herein, the
`
`Individual Defendants were each involved in negotiating, reviewing, and approving the Proposed
`
`Transaction. The Proxy Statement purports to describe the various issues and information that
`
`they reviewed and considered—descriptions the Company directors had input into.
`
`40.
`
`By virtue of the foregoing, the Individual Defendants have violated Section 20(a)
`
`of the Exchange Act.
`
`41.
`
`As set forth above, the Individual Defendants had the ability to exercise control
`
`over and did control a person or persons who have each violated Section 14(a) and SEC Rule 14a-
`
`9, promulgated thereunder, by their acts and omissions as alleged herein. By virtue of their
`
`positions as controlling persons, these defendants are liable pursuant to Section 20(a) of the
`
`Exchange Act. As a direct and proximate result of defendants’ conduct, Aerpio stockholders will
`
`be irreparably harmed.
`
`PRAYER FOR RELIEF
`
`WHEREFORE, Plaintiff demands judgment and preliminary and permanent relief,
`
`including injunctive relief, in his favor on behalf of Aerpio, and against defendants, as follows:

`Preliminarily and permanently enjoining defendants and all persons acting in
`
`concert with them from proceeding with, consummating, or closing the Proposed Transaction and
