Opinion

HALL, Circuit Judge:

Plaintiff-Appellant Gary Kleinman (“Kleinman”) appeals from the judgment of the district court (Hellerstein, J.) dismissing Kleinman’s amended complaint with prejudice for failure to state a cause of action under Fed.R.Civ.P. 12(b)(6) and denying leave to amend. Kleinman alleges that Defendants-Appellees Elan Corporation, pic (“Elan”), Pfizer, Inc. (“Pfizer”) (as successor-in-interest to Wyeth, Inc. (“Wyeth”)), G. Kelly Martin, and Lars Ekman (collectively, the “Defendants”) violated Section 10(b) and Section 20(a) of the Securities Exchange Act of 1934 by issuing a misleading press release on June 17, 2008 (the “June press release”) concerning the results of a clinical trial for a drug called bapineuzumab (then under joint development by Elan and Wyeth). Kleinman brought this putative class action on behalf of all those who purchased Elan’s call options during the Class Period — June 17, 2008, to July 29, 2008. He alleges the press release omitted several facts that, in his view, were necessary to prevent the press release from being misleadingly optimistic. We write to explain how, in the context of the full presentation of the details surrounding the study of the drug, nothing omitted from the June press release rendered it false or misleading to a reasonable investor. Moreover, we hold that Kleinman offered insufficient additional allegations to cure this deficiency. For the reasons that follow, we affirm the judgment of the district court.

Background

We draw the following facts from Klein-man’s amended complaint, written instruments attached to it, and statements or documents incorporated by reference. See Chambers v. Time Warner, Inc., 282 F.3d 147, 152 (2d Cir.2002).

Elan is a neuroscience-based biotech company with operations in New York, California, and Pennsylvania. Elan’s American Depositary Receipts (“ADRs”) are traded on the New York Stock Exchange and its publicly traded call options are derivative of, and trade in tandem with, Elan’s ADRs. Wyeth was a Delaware Corporation before its acquisition by Pfiz *148 er in October 2009. During the relevant timeframe, Wyeth and Elan had a joint project aimed at researching, developing, and eventually marketing drugs designed to treat mild to moderate Alzheimer’s.

Estimates show that more than five million Americans currently suffer from Alzheimer’s, and that count is expected to grow as the population ages. The current panoply of drugs on the market treat only the symptoms of Alzheimer’s — loss of cognition and function — and for only a short time. Elan and Wyeth developed bapineuzumab, which was designed to clear and prevent the toxic beta-amyloid plaques that build up in the brain. Some scientists believe these plaques are the main cause of the symptoms of the disease.

Before presentation of a new drug to the FDA, pharmaceutical companies are required to engage in three phases of clinical trials, with each phase growing in complexity and size, before ultimate presentation to the FDA. 2 Phase 1 consists of a closely monitored, relatively small study (twenty to eighty volunteers) to determine the safety of the drug and, if possible, early evidence of effectiveness. See 21 C.F.R. § 312.21(a). Phase 2 involves further clinical research and study to determine the drug’s efficacy and any “common short-term side effects and risks associated with the drug.” Id. § 312.21(b). Finally, Phase 3 clinical trials “are performed after preliminary evidence suggesting effectiveness of the drug has been obtained” and usually include “several hundred to several thousand subjects.” Id. § 312.21(c).

After completing a successful Phase 1 trial for bapineuzumab, Wyeth and Elan designed the Phase 2 study to measure bapineuzumab’s overall effectiveness and safety. That study consisted of a 240-patient, randomized, double-blind, placebo-controlled study. 3 Patients enrolled in Phase 2 on a rolling basis, so although the trial began in April 2005, it was not complete until April 2008. Bapineuzumab’s effectiveness was measured by common diagnostics that test cognition and dementia. The two primary tests were the ADAS-Cog 4 and the Disability Assessment Scale for Dementia (“DAD”). The Phase 2 trial, as planned, used a standard model with certain assumptions. Phase 2 also predesignated certain goals — endpoints — by which success would be measured based on how patients performed at the end of the study using the ADAS-Cog and DAD tests. Phase 2 included, as additional tests, changes in spinal fluid and brain volume. Patients’ progress was also examined using the Neuropsychological Test Battery, the Clinical Dementia Rating Sum of Boxes, and the Mini-Mental State Examination (“MMSE”).

Having taken an interim look at the Phase 2 data in May 2007, Elan and Wyeth *149 announced that they would commence Phase 3 for bapineuzumab later that year. The Phase 3 trials involve approximately 4,000 patients and include four randomized, double-blind studies across two subgroup populations.

In April 2008, Elan announced that while Phase 2 remained ongoing, it (along with Wyeth) expected to present a “top line finding some time around mid-year [2008]” and a “full data review” of Phase 2 at the International Conference on Alzheimer’s Disease (“ICAD”) in Chicago on July 29, 2008. In line with that plan, Wyeth and Elan jointly issued the June press release, informing the public of the top-line results for Phase 2 in advance of the ICAD. That press release forms the basis of this litigation.

The June press release stated that although “[t]he study did not attain statistical significance on the primary efficacy endpoints in the overall study population[, p]ost-hoc analyses did show statistically significant and clinically meaningful benefits in important subgroups.” J.A. 237. The main headline of the June press release stated that Phase 2 resulted in “Encouraging Top-line Results.” Id. A sub-headline also announced that “Primary Efficacy Endpoints In Overall Study Population [Were] Not Statistically Significant.” The positive results, the June press release stated, were seen in a subgroup of the Alzheimer’s population: non-carriers of the Apolipoprotein (“ApoE4”) gene. Id. Specifically, with regard to

non-carriers of the [ApoE4] allele, estimated in the literature to be from 40 to 70 percent of the Alzheimer’s disease population, posthoc analyses showed statistically significant and clinically meaningful benefits associated with bapineuzumab treatment on several key efficacy endpoints, including the Alzheimer’s Disease Assessment Scale (ADAS-cog), the Neuropsychological Test Battery (NTB), the [MMSE] and the Clinical Dementia Rating — Sum of Boxes (CDR-SB). A favorable directional change was seen on the [DAD], although this was not statistically significant.
