Glancy Prongay & Murray LLP Continues Investigation on Behalf of Proteostasis Therapeutics, Inc. Investors (PTI)

LOS ANGELES--()--Glancy Prongay & Murray LLP (“GPM”) continues its investigation on behalf of Proteostasis Therapeutics, Inc. (“Proteostasis” or the “Company”) (NASDAQ: PTI) investors concerning the Company and its officers’ possible violations of federal securities laws. To obtain information or aid in the investigation, please visit the Proteostasis investigation page on our website at www.glancylaw.com/case/proteostasis-therapeutics-inc.

On March 20, 2018, Kerrisdale Capital Management LLC published a report alleging that the Company’s claimed success of its Phase 2 proof-of-concept trial of PTI-428 “stems almost entirely from the anomalously bad performance of the 4-person placebo group, while, on average, patients taking PTI-428 barely improved.” The report also claimed that “Proteostasis has a habit of sweeping unpleasant or confusing findings under the rug.” On this news, shares of Proteostasis fell $1.83, or 26%, to close at $5.16 on March 20, 2018, thereby injuring investors.
