Dr. Rainer Hoffmann joined the Lohmann Group in 1979. Realising the potential for transdermal delivery systems he immediately set to work at developing a nitroglycerin drug delivery patch, launched in 1983. In 1984, the Lohmann group spun out the transdermal division under the name Lohmann Therapie System (LTS), of which Dr. Hoffmann became CEO and Chairman of the Executive Board. Today, LTS is one of the world leaders in the design, development and manufacturing of transdermal drug products. In late 2011 Dr. Hoffmann retired from LTS and started a private equity activity geared toward start-up biopharma companies. Dr. Hoffmann has also been Chairman of the Supervisory Board of SCS Skin Care Systems GmbH (Andernach, Germany), Smartrix Technologies Inc. (Canada), IKP- Institut für Klinische Pharmakologie Bobenheim Prof. Dr. Lücker GmbH (Grünstadt, Germany), ECS Environment Care Systems GmbH (Andernach, Germany) and CRS Clinical Research Services Andernach GmbH (Andernach, Germany) and was a Member of the Board of Directors of LAB International SRL (Barbados).
