Press Release

BRIDGEWATER, N.J., Feb. 23, 2016 /PRNewswire/ -- Sanofi announced today that the license and development agreement between Sanofi and kaléo, formerly Intelliject Inc., the developer of Auvi-Q® (epinephrine injection, USP), will terminate later this year. At that time, all U.S. and Canadian rights will be returned to kaléo. Sanofi is in discussions with kaléo on these terms and for an orderly transition plan. Kaléo will evaluate timing and options for bringing Auvi-Q back to market.
