NEW YORK, NY / ACCESSWIRE / January 19, 2023 / Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of Karyopharm Therapeutics Inc. ('Karyopharm' or the 'Company') (NASDAQ:KPTI). Investors who purchased Karyopharm securities are encouraged to obtain additional information and assist the investigation by visiting the firm's site: www.bgandg.com/kpti.
The investigation concerns whether Karyopharm has violated federal securities laws.
On February 8, 2022, Karyopharm reported 'successful'-though ultimately disappointing-results from its Phase 3 SIENDO Study of Xpovio for the treatment of endometrial cancer. Specifically, the treatment reduced patients' risk of disease progression or death by 30%, just barely enough to be considered statistically significant, and median progression-free survival was just 5.7 months compared to 3.8 months among patients randomized to receive a placebo. On this news, Karyopharm's stock price fell $2.05 per share, or 20.02%, to close at $8.19 per share on February 8, 2022.
Then, on March 1, 2022, Karyopharm reported negative feedback from the U.S. Food and Drug Administration ('FDA') on its supplemental NDA for Xpovio based on the Phase 3 SIENDO Study results for endometrial cancer. Specifically, the FDA found that the current results would not support NDA approval as Karyopharm and the FDA participants had differing views on the study's significance and overall clinical benefit for the whole population. On this news, Karyopharm's stock price fell $4.13 per share, or 39.75%, to close at $6.26 per share on March 2, 2022.
