Karyopharm Therapeutics Inc. Securities Litigation
On or around 11/09/2020 (Date of last review)
Filing Date: July 23, 2019
According to the Complaint, Karyopharm is a clinical-stage pharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer and other major diseases. During the Class Period, Karyopharm’s lead drug candidate was selinexor, an oral selective inhibitor of nuclear export for the treatment of cancer indications with significant unmet clinical need, initially to be used for the treatment of blood cancers.
The Complaint alleges that during the Class Period, Defendants falsely represented the safety and efficacy of selinexor. Specifically, the Complaint alleges Defendants' material misrepresentations and omissions center on Defendants' claims regarding results from clinical trials for selinexor's treatment of patients with certain types of blood cancer.
This case was voluntarily dismissed on March 12, 2020. A related case continues under Docket 19-CV-11972.
On April 29, 2020, the Court issued an Order appointing Lead Plaintiff and Counsel. Lead Plaintiff filed an amended Complaint on June 29. On October 22, Lead Plaintiff filed a second amended Complaint.

About the Company & Securities Data
"Company" information provides the industry and sector classification and headquarters state for the primary company-defendant in the litigation. In general, "Securities" information provides the ticker symbol, market, and market status for the underlying securities at issue in the litigation.
In most cases, the primary company-defendant actually issued the securities that are the subject of the litigation, and the securities information and company information relate to the same entity. In a small subset of cases, however, the primary company-defendant is not the issuer (for example, cases against third party brokers/dealers), and the securities information and company information do not relate to the same entity.
