On March 20, 2018, Kerrisdale Capital Management published a report entitled "Proteostasis Therapeutics, Inc.: Hyped-Up Lung Data? Just a Lot of Hot Air."  The report asserted that in the Phase 2 study for the Company's cystic-fibrosis drug, PTI-428, "the placebo group's small size and anomalously bad outcomes misleadingly make the treatment group's unimpressive results look good by comparison."  Accordingly, the report concluded that the drug "is ineffective and will likely fail future Phase 3 trials."  On this news, Proteostasis's share price has fallen sharply during intraday trading on March 20, 2018.
