Shares of Forte Biosciences Inc. (NASDAQ:FBRX) touched a 52-week low, diving 82.3% to close at $5.06 on Sept. 3 after its sole candidate, FB-401, failed to make a statistically significant difference in improving the severity of atopic dermatitis. The result, contrasting starkly with a smaller positive trial, led CEO Paul Wagner to announce the company would quit development of the FDA fast-tracked asset, licensed from the U.S. National Institute of Allergy and Infectious Diseases.

The FDA has approved Korsuva (difelikefalin) from Cara Therapeutics Inc. for pruritis in patients undergoing hemodialysis, following a fast review. Korsuva is the first therapy approved by the FDA in the indication and is the first ever approval for the Stamford, Conn.-based company.
