  CASE CAPTION	In re Celgene Corporation Securities Litigation
  COURT	United States District Court for the District of New Jersey
  CASE NUMBER	2:18-cv-04772-JMV-JBC
  JUDGE	Honorable John Michael Vazquez and Honorable James B. Clark, III
  PLAINTIFF	AMF Pensionsförsäkring AB (“AMF”)
  DEFENDANTS	Celgene Corporation (“Celgene”), Scott A. Smith, Terrie Curran, and Philippe Martin
  CLASS PERIOD	April 27, 2017 through April 27, 2018, inclusive

  This securities fraud case involves Celgene’s misrepresentations and omissions about two billion dollar drugs, Otezla and Ozanimod, that Celgene touted as products that would make up for the anticipated revenue drop following the patent expiration of Celgene’s most profitable drug, Revlimid.

  Celgene launched Otezla, a drug treating psoriasis and psoriatic arthritis, in 2014. Celgene primed the market that Otezla sales were poised to sky-rocket, representing that Otezla net product sales would reach $1.5 billion to $2 billion by 2017. Throughout 2015 and 2016, Defendants represented that Celgene was on-track to meet the 2017 sales projection. As early as mid-2016, however, Defendants received explicit internal warnings that the 2017 projection was unattainable, but continued to reaffirm the 2017 target to investors. By October 2017, however, Celgene announced that the Company had slashed the 2017 guidance by more than $250 million and lowered the 2020 Inflammatory & Immunology (“I&I”) guidance by over $1 billion. Celgene’s stock price plummeted on the news.

  Ozanimod, a drug treating multiple sclerosis, is another product in Celgene’s I&I pipeline, and was initially developed by a different company, Receptos. In July 2015, Celgene purchased Receptos for $7.2 billion and projected annual Ozanimod sales of up to $6 billion despite the fact that Ozanimod was not yet approved by the U.S. Food and Drug Administration (“FDA”).

  Celgene told investors that it would file a New Drug Application (“NDA”) for Ozanimod with the FDA in 2017. Unbeknownst to investors, however, Celgene discovered a metabolite named CC112273 (the “Metabolite”) through Phase I testing that Celgene started in October 2016, which triggered the need for extensive testing that was required before the FDA would approve the drug. Despite the need for this additional Metabolite testing that would extend beyond 2017, Defendants continued to represent that Celgene was on track to submit the NDA before the end of 2017 and concealed all information about the Metabolite.  In December 2017, without obtaining the required Metabolite study results, Celgene submitted the Ozanimod NDA to the FDA. Two months later, the FDA rejected the NDA by issuing a rare “refuse to file,” indicating that the FDA “identifie[d] clear and obvious deficiencies” in the NDA.  When the relevant truth was revealed concerning Ozanimod, Celgene’s stock price fell precipitously, damaging investors.   

  On February 27, 2019, AMF filed a 207-page Second Amended Consolidated Class Action Complaint against Celgene and its executives under Section 10(b) of the Securities Exchange Act. On December 19, 2019, U.S. District Judge John Michael Vasquez issued a 49-page opinion sustaining AMF’s claims as to (1) Celgene’s and Curran’s misstatements regarding Otezla being on track to meet Celgene’s 2017 sales projections, and (2) Celgene’s, Martin’s, and Smith’s misstatements about the state of Ozanimod’s testing and prospects for regulatory approval.

  On November 29, 2020, Judge Vasquez certified a class of “All persons and entities who purchased the common stock of Celgene Corp. between April 27, 2017 through and April 27, 2018, and were damaged thereby” and appointed Kessler Topaz Meltzer & Check as Class Counsel.

  On July 9, 2021, Plaintiff moved to amend the Second Amended Complaint and file the Third Amended Complaint, which alleged a new statement regarding Otezla, and added new allegations based on evidence obtained in discovery regarding Ozanimod. On February 24, 2022, Magistrate Judge James B. Clark granted the motion to amend, which Defendants appealed. On June 1, 2022, Judge Vazquez issued an opinion denying Defendants’ appeal. Expert discovery is ongoing.

• Goldman Sachs Group, Inc.

  CASE CAPTION	Sjunde AP-Fonden v. The Goldman Sachs Group, Inc. et al.
  COURT	United States District Court for the Southern District of New York
  CASE NUMBER	1:18-cv-12084-VSB
  JUDGE	Honorable Vernon S. Broderick
  PLAINTIFF	Sjunde AP-Fonden (“AP7”)
  DEFENDANTS	The Goldman Sachs Group (“Goldman Sachs” or the “Company”), Lloyd C. Blankfein, Gary D. Cohn, and Harvey M. Schwartz
  CLASS PERIOD	February 28, 2014 to December 20, 2018, inclusive

  This securities fraud class action case arises out of Goldman Sachs’ role in the 1Malaysia Development Berhad (“1MDB”) money laundering scandal, one of the largest financial frauds in recent memory.

  In 2012 and 2013, Goldman served as the underwriter for 1MDB, the Malaysia state investment fund masterminded by financier Jho Low, in connection with three state-guaranteed bond offerings that raised over $6.5 billion. Goldman netted $600 million in fees for the three bond offerings—over 100 times the customary fee for comparable deals.

  In concert with Goldman, Low and other conspirators including government officials from Malaysia, Saudi Arabia, and the United Arab Emirates ran an expansive bribery ring, siphoning $4.5 billion from the bond deals that Goldman peddled as investments for Malaysian state energy projects. In actuality, the deals were shell transactions used to facilitate the historic money laundering scheme. Nearly $700 million of the diverted funds ended up in the private bank account of Najib Razak, Malaysia’s now-disgraced prime minister who was convicted for abuse of power in 2020. Other funds were funneled to Low and his associates and were used to buy luxury real estate in New York and Paris, super yachts, and even help finance the 2013 film “The Wolf of Wall Street.”

  AP7 filed a 200-page complaint in October 2019 on behalf of a putative class of investors alleging that Goldman and its former executives, including former CEO Lloyd Blankfein and former President Gary Cohn, violated Section 10(b) of the Securities Exchange Act by making false and misleading statements about Goldman’s role in the 1MDB fraud. As alleged, when media reports began to surface about the collapse of 1MDB, Goldman denied any involvement in the criminal scheme. Simultaneously, Goldman misrepresented its risk controls and continued to falsely tout the robustness of its compliance measures. Following a series of revelations about investigations into allegations of money laundering and corruption at 1MDB, Goldman’s stock price fell precipitously, causing significant losses and damages to the Company’s investors.

  In October 2020, the U.S. Department of Justice announced that Goldman’s Malaysia subsidiary had pled guilty to violating the Foreign Corrupt Practices Act (“FCPA”) which criminalizes the payment of bribes to foreign officials, and that Goldman had agreed to pay $2.9 billion pursuant to a deferred prosecution agreement. This amount includes the largest ever penalty under the FCPA.

  On June 28, 2021, The Honorable Vernon S. Broderick of the U.S. District Court for the Southern District of New York sustained Plaintiff's complaint in a 44-page published opinion.  Plaintiff moved for class certification in November 2021.  That motion is fully briefed and pending before the Court.  Fact discovery is ongoing.  On January 13, 2023, Plaintiff moved for leave to amend the Complaint.  Briefing on that motion is set conclude in February 2023.

  JUDGE	Honorable Madeline Cox Arleo and Honorable Leda Dunn Wettre
  PLAINTIFF	Carmignac Gestion, S.A., First Manhattan Co., Schwab Capital Trust, et al., Principal Funds, Inc., Kuwait Investment Authority, et al., Nationwide Mutual Funds, et al., and Aberdeen Canada Funds – Global Equity Fund, et al.
  DEFENDANTS	Perrigo Company plc (“Perrigo”), Joseph C. Papa, and Judy L. Brown
  CLASS PERIOD	April 21, 2015 through May 3, 2017, inclusive

  These seven shareholder opt-out actions stem from drug maker Perrigo’s efforts to mislead investors to stave off a hostile takeover bid by pharmaceutical rival Mylan in 2015.  The plaintiff investment funds allege that Perrigo and its senior officers misrepresented the true state of the company’s $4.5 billion acquisition of Omega Pharma, an over-the-counter healthcare company based in Belgium, and fraudulently touted its ability to withstand pricing pressure from the influx of competing drugs in the generic drug markets.

  In 2018, we filed the first of these actions in the United States District Court for the District of New Jersey on behalf of institutional investors in the United States, the United Kingdom, France, and Kuwait.  The Honorable Madeline Cox Arleo denied Defendants’ motions to dismiss the actions in 2019.  The parties concluded discovery in November 2021 and are awaiting summary judgment motion practice.

  CASE CAPTION	Franklin Mutual Series Funds v. Teva Pharmaceutical Ind. Ltd., et al.; Nordea Investment Management AB v. Teva Pharmaceutical Ind. Ltd., et al.; and State of Alaska, Department of Revenue v. Teva Pharmaceutical Ind. Ltd., et al.
  COURT	United States District Court for the District of Connecticut
  CASE NUMBER	3:18-cv-01681-SRU; 3:18-cv-01721-SRU and 3:20-cv-01630-SRU
  JUDGE	Honorable Stefan R. Underhill
  PLAINTIFF	Franklin Templeton Investment Funds, Nordea Investment Management AB, State of Alaska Department of Revenue, and The Alaska Permanent Fund Corporation
  DEFENDANTS	Teva Pharmaceutical Industries Ltd. (“Teva”), Erez Vigodman, Eyal Desheh, Yaacov Altman, Sigurdur Olafsson, Kåre Schultz, and Michael McClellan
  CLASS PERIOD	February 6, 2014 through May 10, 2019, inclusive

  These securities fraud opt-out actions in Connecticut federal court involve Teva’s concealment of its role in an industrywide conspiracy to fix the prices of generic drugs.  Our clients allege that Teva failed to disclose that the driving force behind its record revenues between 2013 and 2015 was its participation in the price-fixing scheme and reliance on an unsustainable strategy to systematically raise generic drug prices across its portfolio.  When Teva’s role in the price-fixing conspiracy and the true financial consequences of its pricing strategy were revealed, plaintiffs suffered substantial investment losses.  

  In addition to representing multiple U.S. and European investment funds, Kessler Topaz was appointed by U.S. District Judge Stefan R. Underhill to serve as liaison counsel to the Court on behalf of the more than twenty-five opt-out plaintiffs in this consolidated litigation.

Landmark Results

• Pfizer, Inc.

  This securities fraud class action in Manhattan federal court arose out of Pfizer’s concealment of clinical results for two arthritic pain drugs, Celebrex and Bextra. Despite being aware of significant cardiovascular adverse events in clinical trials, Pfizer misrepresented the safety profile of the drugs until the U.S. Food & Drug Administration discontinued a key trial, forced the withdrawal of Bextra from the market, and issued an enhanced warning label for Celebrex. Following a summary judgment order dismissing the case several weeks before trial was set to begin, we successfully appealed the dismissal at the U.S. Court of Appeals for the Second Circuit and the case was remanded for trial.

  After twelve years of litigation, the case resolved in 2016 with Pfizer agreeing to pay the shareholder class $486 million, the largest-ever securities fraud settlement against a pharmaceutical company in the Southern District of New York.

• Allergan Generic Drug Pricing

  Kessler Topaz represented Lead Plaintiff Sjunde-AP Fonden, one of Sweden’s largest pension funds, in this long-running securities fraud class action before The Honorable Katharine S. Hayden of the United States District Court for the District of New Jersey. The $130 million recovery is the first settlement of a federal securities case arising out of the industrywide generic drug price-fixing scandal which first came to light when Congress launched an investigation into the historic increases in generic drug prices. The price-fixing conspiracy, led by Allergan and several other drug makers, is believed to be the largest domestic pharmaceutical cartel in U.S. history. Shareholders alleged that notwithstanding Allergan’s prominent role in this illicit scheme, the company repeatedly misrepresented to investors that it was not engaged in anticompetitive conduct—even as Allergan became ensnared in an investigation by the U.S. Department of Justice and 46 state attorneys general.

  For four years, a team of Kessler Topaz litigators prosecuted these claims from the initial investigation and drafting of the complaint through full fact discovery and class certification proceedings. On August 6, 2019, Judge Hayden issued a 31-page opinion denying defendants’ motions to dismiss the complaint, sustaining investors’ claims in full, and firmly establishing a shareholder-plaintiff’s ability to pursue securities fraud claims based on the concealment of an underlying antitrust conspiracy. The parties’ settlement was approved by the Court on November 22, 2021, marking a historic recovery for investors and sending a strong message to drug makers engaged in anticompetitive conduct.

• Citigroup, Inc.

  We represented the Miami Beach Employees’ Retirement Plan, the Philadelphia Public Employees’ Retirement System, the Southeastern Pennsylvania Transportation Authority Pension Fund, and the City of Tallahassee Pension Plan in this historic class action against Citigroup before Judge Sidney H. Stein of the Southern District of New York.  Plaintiffs and a class of Citigroup bondholders alleged that Citigroup concealed its exposure to subprime mortgage debt on the eve of the 2008 financial crisis—exposure that, once revealed, led to massive investment losses.  The $730 million settlement is believed to be the second largest recovery ever for a Section 11 claim under the Securities Act on behalf of corporate bondholders.  

• J.P. Morgan Chase & Co.

  This securities fraud class action in the United States District Court for the Southern District of New York stemmed from the “London Whale” derivatives trading scandal at JPMorgan Chase. Shareholders alleged that JPMorgan concealed the high-risk, proprietary trading activities of the investment bank’s Chief Investment Office, including the highly volatile, synthetic credit portfolio linked to trader Bruno Iksil—a.k.a., the “London Whale”—which caused a $6.2 billion loss in a matter of weeks. Shareholders accused JPMorgan of falsely downplaying media reports of the synthetic portfolio, including on an April 2012 conference call when JPMorgan CEO Jamie Dimon dismissed these reports as a “tempest in a teapot,” when in fact, the portfolio’s losses were swelling as a result of the bank’s failed oversight.

  This case was resolved in 2015 for $150 million, following U.S. District Judge George B. Daniels’ order certifying the class, representing a significant victory for investors.
