MBVX Class Action Report

Levi & Korsinsky, LLP

June 7, 2018

On June 4, 2018, investors sued MabVax Therapeutics Holdings (“MabVax” or the “Company”) in United States District Court, Southern District of California. Plaintiffs in the federal securities class action allege that they acquired MabVax stock at artificially inflated prices between March 14, 2016 and May 18, 2018 (the “Class Period”). They are now seeking compensation for financial losses incurred upon public revelation of the Company’s alleged misconduct during that time. Here’s everything you need to know about the MabVax class action lawsuit (MBVX class action lawsuit):


Summary of the Allegations

Company Background

MabVax (NASDAQ: MBVX) bills itself as “a clinical-stage biotechnology company with a fully human antibody discovery platform focused on the clinical development of products to address unmet medical needs for the treatment of cancer.”

As such, the Company works through its subsidiaries to develop human antibody-based products and vaccines. These are then used in the treatment of sarcoma and pancreatic, lung, ovarian and breast cancer.

Summary of Facts

MabVax and two of its senior officers and/or directors now stand accused of deceiving investors by lying and withholding critical information about the Company’s business practices during the Class Period.

Specifically, they are accused of omitting truthful information about the efficacy of MabVax’s controls over financial reporting, and the calculation and reporting of beneficial share ownership from SEC filings and related material. By knowingly or recklessly doing so, they allegedly caused MabVax stock to trade at artificially inflated prices during the time in question.

The truth began to surface on January 30, 2018, when the Company filed a form with the SEC in which it disclosed it that the SEC was investigating it.

Then, on May 21, 2018, the Company filed another form with the SEC in which it disclosed additional details about the nature of the investigation. Specifically, the Company acknowledged that the agency was investigating “the Company and its officers and directors’ potential violation of federal securities laws.” The Company also acknowledged that the SEC was looking into “potential violations of securities laws by various holders of the Company’s securities.”

A closer look…

As alleged in the June 4 complaint, the MabVax repeatedly made misleading public statements during the Class Period.

For example, in an annual report filed with the SEC on March 14, 2016, the Company discussed its “Financing Activities” and the effectiveness of its financial controls. In this context it stated in relevant part: “We conducted an evaluation of the effectiveness of internal control over financial reporting based on the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our principal executive officer and principal financial officer conclude that, at December, 31, 2015, our internal control over financial reporting was effective.”

The Company also reiterated the statement in annual reports filed with the SEC on March 1, 2017 and April 2, 2018.
