Opinion

PAUL A. ENGELMAYER, District Judge:

*381In this putative class action under the federal securities laws, lead plaintiffs Michael Gregory, Yeshan Jagroo, and Mindy Frost (collectively, "plaintiffs") claim that pharmaceutical company ProNAi Therapeutics Inc.1 ("ProNAi"), its CEO and President Nick Glover ("Glover"), and its CFO Sukhi Jagpal ("Jagpal") (together, "ProNAi" or "defendants") made false and misleading statements touting the prospects of PNT2258, ProNAi's sole drug candidate. These statements were made between July 15, 2015, the day ProNAi's initial public offering prospectus was released, and June 6, 2016, the day ProNAi announced the discontinuation of development of PNT2258.

Plaintiffs bring this lawsuit on behalf of all persons who purchased ProNAi securities between July 15, 20152 and June 6, 2016 (the "Class Period"). They allege violations of §§ 10(b) and 20(a) of the Securities Exchange Act of 1934 (the "Exchange Act") and the corresponding rule of the Securities and Exchange Commission, 17 C.F.R. § 240.10b-5 ("Rule 10b-5").

Pending now is ProNAi's motion to dismiss the Amended Class Action Complaint ("AC") for failure to state a claim under Federal Rules of Civil Procedure 12(b)(6) and 9(b). For the following reasons, the Court grants the motion and dismisses the AC in its entirety.

I. Background3

After identifying the parties, the Court here sets out, at length, the chronology of events regarding PNT2258. This rendition is lengthy because plaintiffs allege that, during the Class Period, ProNAi made some 70 false and misleading statements, spanning a series of disclosures, and because the statements alleged to be actionable concern the status of PNT2258 at various points in its complex testing and *382development. As a general proposition, plaintiffs' core theory is that ProNAi consistently overstated PNT2258's prospects, downplayed or failed to disclose historical and more recent negative test results, and identified as risk factors circumstances that had already come to pass. The 70 statements that plaintiffs claim to be actionable misstatements or omissions are listed chronologically in the Appendix to this decision. For ease of reference, they are identified there and here as misstatements ("MS") 1 through 70.

A. Parties

ProNAi is "a clinical stage oncology company with a focus on pioneering a novel class of therapeutics based on its proprietary DNA interference (DNAi) technology platform." AC at 9. "Throughout the Class Period, PNT2258 (a DNAi drug) was the Company's only drug product candidate and, thus, the successful development of PNT2258 was critical to ProNAi's long-term viability." Id.

The individual defendants are Glover, ProNAi's President and CEO and a member of its board since September 2014, and Jagpal, ProNAi's CFO since February 2015 (collectively, the "Individual Defendants"). Id. at 7-8.

The lead plaintiffs all purchased ProNAi securities during the Class Period. Id. at 6.

B. Pre-Class Period Events

1. PNT2258

During the Class Period, PNT2258 was ProNAi's lead product candidate and the company's only drug in clinical development. Id. at 9, 11. It was developed based on ProNAi's proprietary DNA interference (DNAi) technology platform. Id. at 11.

As ProNAi described DNAi technology, it is based on a discovery from "Wayne State University and Karmanos Cancer Institute that single-stranded DNA oligonucleotides can interact with genomic DNA" and interfere with gene transcription. See Prospectus at 82. The theory is that those oligonucleotides could be used to interfere with the transcription of genes linked to particular diseases. ProNAi's Prospectus illustrated this concept as follows:

*383Figure 1 (Prospectus at 82)

As the Prospectus illustrated, ProNAi was to use pH-responsive lipid nanoparticles to protect the DNAi oligonucleotide and deliver them across physiological membranes to the cancer cells.

The drug in question here, PNT2258, was within the DNAi class. AC at 13. PNT2258 was designed to target a particular oncogene, BCL2, and interfere with its transcription. Id. at 11. BCL2 gives cancer cells the ability to resist the primary mechanism for the removal of damaged or unnecessary cells, known as apoptosis. Id. By effectively programming cancer cells to survive this naturally occurring process, an overexpression of BCL2 contributes to the formation, growth, and chemo-resistance of a wide range of tumors. Id.

PNT2258 was designed with the goal of restoring the apoptotic process and, thus, killing cancer cells. Id. PNT2258 contains two parts: (1) PNT100, the single-stranded DNAi oligonucleotide that was designed to target a particular regulatory region of BCL2 to limit transcription, and (2) the protective lipid nanoparticles that allow PNT100 to travel to the cancer cell's nucleus so that it can modulate gene transcription. See Prospectus at 85.
