APPEAL FROM THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF MASSACHUSETTS

[Hon. Denise J. Casper, U.S. District Judge]

Before

Thompson, Lipez, and Kayatta, Circuit Judges.

Jeffrey Craig Block, with whom Jacob A. Walker, Nathaniel Silver, and Block & Leviton LLP were on brief, for appellant. Laurence Adam Schoen, with whom John F. Sylvia, Geoffrey A. Friedman, and Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. were on brief, for appellees. July 9, 2021 [REDACTED OPINION]*

*The full version of this opinion was filed on June 21, 2021, and remains on file, under seal, in the Clerk's Office. THOMPSON, Circuit Judge. Before us on appeal is a

dispute between Tim Karth, an investor who lost money when he

bought stock that saw its value plummet soon after that purchase,

and Keryx Biopharmaceuticals, Inc., and its executives, all of

whom allegedly swindled Karth out of his hard-earned cash by

misleading him about the likelihood that Keryx would be able to

continue to meet demand for its only drug product. Though, at

various points, the case contained a myriad of claims and

experienced a long procedural history, the parties agree that the

entirety of the appeal is resolved by addressing one question:

did Keryx sufficiently warn investors about the vulnerability of

its manufacturing infrastructure so that Karth knew of the

investment risks when he purchased his shares? The district court

answered that question in the affirmative and entered judgment for

the defendants, denied Karth's motion for class certification, and

denied Karth's motion to file a third amended complaint. Reviewing

the case with fresh eyes, we affirm.

BACKGROUND

We recite the alleged facts pertinent to our inquiry as

contained in Karth's complaint and attachments incorporated

therein in the light most favorable to the non-movant, Karth. See

Curran v. Cousins, 509 F.3d 36, 43-44 (1st Cir. 2007). Karth's

proposed class consists of anyone who purchased Keryx stock from

May 8, 2013, through August 1, 2016. Karth himself purchased Keryx

- 3 - stock at the end of that class period, on July 19, 2016. 1

Accordingly, the following recitation of the facts is limited to

occurrences during the purported class period, with a particular

focus on the events of 2016, the year of Karth's stock purchase

and Keryx's supply shortage. We set forth the facts

chronologically, interspersing information about manufacturing

difficulties with information Keryx made known to the public.

Keryx's Leadership and Manufacturing Process

At all relevant times, Keryx was a Boston-based

biopharmaceutical company. The four individual defendants served

in different corporate roles. Ron Bentsur was Keryx's CEO.

Gregory P. Madison was Keryx's COO starting February of 2014 and

took over for Bentsur as CEO at the end of April of 2015. James

Oliviero served as CFO for Keryx from May of 2003 until July of

2015, when he was replaced by Scott A. Holmes.

During the proposed class period, Keryx commenced

production and sale of its only product, a drug named Auryxia.

There were two steps in the Auryxia production process. Step one

was manufacturing the active pharmaceutical ingredient ("API") and

1Karth's First Amended Complaint (the operative pleading at the time the district court granted judgment for the defendants) pleads that the class period ends on August 1, 2016, but his proposed Third Amended Complaint alleges a class period ending on July 29, 2016, or July 31, 2016. We utilize the August 1, 2016, date because that date seems to be the date he cites most consistently, but the outcome would not be altered by the class period ending on any of Karth's listed dates.

- 4 - step two was converting the API into its finished tablet form.

The tablet, when prescribed by a doctor, was used to treat kidney

disease. Keryx lacked the ability to complete any manufacturing

itself and relied upon third-party contractors for each step of

the process. Keryx appears to have enlisted several first-step

manufacturers to produce API. As for step two, during the relevant

time frame, Keryx only contracted with Norwich Pharmaceuticals,

Inc. ("Norwich"), whose principal place of business is Norwich,

New York, to complete the process of converting the API into the

final product, tablets of Auryxia.

The Early Days: 2013-2015

On May 8, 2013, the first day of Karth's proposed class

period, Keryx released a 10-Q form2 that warned investors of the

following risk:

We rely on third parties to manufacture and analytically test our drug candidate. If these third parties do not successfully manufacture and test our drug candidate, our business will be harmed. We have limited experience in manufacturing products for clinical or commercial purposes. We intend to continue, in whole or in part, to use third parties to manufacture and analytically test our drug candidate for use in clinical trials and for future sales. We may not be able to enter into future contract agreements with

2 The SEC requires public companies to file a comprehensive report about their financial performance, called a 10-Q, at the end of the first three quarters of each fiscal year. 17 C.F.R. § 249.308a.

- 5 - these third[]parties on terms acceptable to us, if at all. (Emphases added.)

Beginning in 2014, Norwich experienced problems with the

process of converting API into Auryxia tablets. In May, one API

contractor asked Keryx to "quarantine" the API that company had

produced pending the outcome of a quality control investigation.

In June, Norwich notified Keryx that it "rejected" two batches of

Auryxia due to contamination found in a tablet. In July, in

response to those reports, Keryx instructed Norwich to stop

production, but ordered it to resume the next day, which it did.

Shortly after Keryx began navigating these manufacturing

glitches, it was also preparing to meet with Food and Drug

Administration ("FDA") officials. To that end Keryx enlisted the

help of a consultant, Parexel International, to "assess the

readiness [of Norwich] in preparation for an FDA pre-approval

inspection." Parexel's work, which took place on August 14 and

15, 2014, consisted of a "conference room review of documentation

available relative to the production and controls [of Auryxia]

that would likely be reviewed during an FDA inspection." Parexel

did not visit Norwich's production facilities. Once it completed

its assessment, it sent Bentsur a report on August 22. In it,

Parexel found that Norwich had the "appropriate facilities and

expertise to meet the needs of Keryx," but warned that Norwich was

employing an uncommon system for validating the quality of each

- 6 - step of the production. Given Norwich's approach, the Parexel
