Investigation 

Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of Ionis Pharmaceuticals, Inc. ("Ionis" or "the Company") (NASDAQ: IONS). The investigation concerns whether Ionis and certain of its officers and/or directors have violated federal securities laws.

 

On March 22, 2021, post-market, Ionis issued a press release announcing that “its partner, Roche, has decided to discontinue dosing in the Phase III GENERATION HD1 study of tominersen in manifest Huntington's disease (HD).”  Ionis specified that “[t]he decision was based on the results of a pre-planned review of data from the Phase III study conducted by an unblinded Independent Data Monitoring Committee (iDMC).  While there were no new or emerging safety signals identified for tominersen, the iDMC made its recommendation based on the investigational therapy's potential benefit/risk profile for study participants.”  On this news, Ionis’s stock price fell $12.05 per share, or 21.66%, to close at $43.59 per share on March 23, 2021.
