MEMORANDUM & ORDER

GORTON, J.

This putative securities fraud class action is brought by lead plaintiff Tunc Toker (“Toker”) on behalf of himself and other similarly situated investors against Alnylam Pharmaceuticals, Inc., its Chief Executive Officer, its Chief Financial Officer and other executives (collectively “Alnylam” or “defendants”). Toker alleges that defendants made false and/or misleading statements regarding the efficacy and marketability of its therapeutic injection for the treatment of hereditary ATTR amyloidosis during the class period. Toker brings this purported class action asserting claims against Alnylam and certain Alnylam executives pursuant to Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (“the Exchange Act”). Pending before this Court is the defendants’ motion to dismiss. For the following reasons that motion will be allowed. I. Facts

Alnylam is a biopharmaceutical company incorporated in Delaware with its principal place of business in Cambridge, Massachusetts. The company develops and commercializes treatments for hereditary transthyretin-mediated amyloidosis (“hATTR amyloidosis” or “hATTR”), a gene mutation that causes a potentially harmful build-up of certain proteins in the body’s nerves and organs. hATTR amyloidosis manifests in two ways: damage affecting the nerves (polyneuropathy) and damage impacting the heart (cardiomyopathy). Patients often exhibit both manifestations. Alnylam develops its therapeutics based on RNA interference (“RNAi”) which inhibits the formation of those

disease-causing proteins. In December, 2017, based on study data from their clinical trial, Phase 3 APOLLO (“APOLLO”), Alnylam submitted to the Food and Drug Administration (“the FDA”) a new drug application and marketing authorization application for patisiran (trade name Onpattro) (“Onpattro” or “patisiran”) for the treatment of both the polyneuropathy and cardiomyopathy manifestations of hATTR. APOLLO was designed primarily to evaluate the efficacy and safety of Onpattro for hATTR amyloidosis patients with polyneuropathy. Accordingly, the study’s primary endpoint was to determine the efficacy of patisiran for such patients. APOLLO’s secondary endpoints sought to measure the efficacy of

patisiran on various other metrics, including cardiac health. In addition to primary and secondary endpoints, the study included several exploratory endpoints, also including cardiac assessments. Because hATTR causes both polyneuropathy and cardiomyopathy, often in the same patients, the trial included patients with the cardiac manifestation of the disease known as the cardiac sub-population. Within that sub-population, APOLLO contained metrics to evaluate patisiran’s efficacy for cardiomyopathy. In September, 2017, Alnylam received data from APOLLO and, while discussing the study on a conference call with investors,

announced that APOLLO met its primary and secondary efficacy endpoints. Following that announcement, Alnylam’s stock (which trades on the NASDAQ Stock Exchange) rose from $75.04 to $113.84 per share, a 51% increase. The Amended Complaint alleges that, simultaneously, Alnylam claimed that APOLLO supported an FDA approval for cardiomyopathy. Shortly thereafter, an investigator in the study presented the full dataset at an hATTR meeting in Paris. In November and December, 2017, Alnylam submitted a New Drug Application (“NDA”) to the FDA, using the results from APOLLO, and seeking approval of the drug for all manifestations of hATTR. In August, 2018, the FDA approved patisiran for the

treatment of polyneuropathy caused by hATTR amyloidosis but did not approve the drug for treatment of cardiomyopathy. Further, the FDA approval did not include any labeling with respect to cardiomyopathy. In contravention of the FDA, however, the European Medicines Agency (“the EMA”) approved Onpattro for all manifestations of hATTR (in patients with polyneuropathy) and included cardiac data on the drug label. After the FDA’s announcement that patisiran would not be approved for cardiomyopathy, Alnylam’s stock price fell by almost 6% from $97.38 to $90.95. The price subsequently rebounded, however, and by September 11, 2018, had risen to $100.35 per share.

On September 12, 2018, the FDA released a report discussing its review of paisiran and the approval process (“the FDA report”). That day several securities analysts reported that the FDA report revealed a greater risk with respect to certain trials of Onpattro and a more limited market opportunity for the drug than previously thought. The analysts’ reports suggested that the FDA was concerned by cardiac deaths in patients treated with Onpattro and that Alnylam did not provide sufficient cardiac efficacy data to support approval. After the FDA report was published, Alnylam’s price per share fell by over 5% from $100.35 to $94.75. The Amended Complaint alleges that between February 15,

2018, and September 12, 2018 (“the Class Period”), defendants made materially misleading statements about the cardiac efficacy and safety of patisiran and APOLLO’s results in violation of Section 10(b), SEC Rule 10b-5 and Section 20(a) of the Exchange Act. It alleges that, as a result of that decline in market value, investors who purchased Alnylam stock during the Class Period in reliance on defendants’ false and/or misleading statements suffered significant losses. II. Procedural History

In September, 2018, Carol Leavitt filed her Complaint in the United States District Court for the Southern District of New York. Shortly thereafter, notice of this putative securities fraud class action was published pursuant to the Private Securities Litigation Reform Act of 1995 (“PSLRA”) on GlobeNewswire, a global business-oriented press release distribution service with substantial operations in North America. 15 U.S.C. § 78u-4(a)(3)(A)(i). In late November, 2018, the case was transferred to this Court. A few days later, putative class members Toker, Leavitt, Edwards and Iappini filed their respective motions to be appointed lead plaintiff pursuant to the PSLRA. Id. In May, 2019, this Court allowed the motion of Tunc Toker for appointment as lead plaintiff and approval of counsel. In July, 2019, plaintiff filed an Amended Complaint. III. Motion to Dismiss

A. Legal Standard

To survive a motion to dismiss for failure to state a claim under Fed. R. Civ. P. 12(b)(6), a complaint must contain “sufficient factual matter” to state a claim for relief that is actionable as a matter of law and “plausible on its face.” Ashcroft v. Iqbal, 556 U.S. 662, 667 (2009) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007)). A claim is facially plausible if, after accepting as true all non- conclusory factual allegations, the court can draw the reasonable inference that the defendant is liable for the misconduct alleged. Ocasio-Hernandez v. Fortuno-Burset, 640 F.3d 1, 12 (1st Cir. 2011). A court may not disregard properly pled factual allegations even if actual proof of those facts is improbable. Id. Rather, the relevant inquiry focuses on the reasonableness of the inference of liability that the plaintiff is asking the court to draw.
