Structure and history

Rentschler was founded in 1927 as pharmaceutical manufacturer in the city of Laupheim, in the southern German state of Baden Württemberg. It remains a family-owned company.

Rentschler moved into biotechnologies in the early 1970s, becoming a specialist in recombinant cell lines by the end of the decade. In 1983, it secured the world’s first market approval for a natural Interferon-ß (Fiblaferon), followed in 1989 by approval for recombinant Interferon-y (Polyferon) and a topical Interferon-ß-gel.

From the late 1990s, Rentschler became a contract developer and manufacturer of biopharmaceuticals, expanding to North America with the 2006 establishment of Rentschler, Inc.

Between 2008 and 2012, the company presided over a significant expansion of manufacturing capacity for installation of 3,000 L stainless steel bioreactor and two 1,000 L single-use bioreactors. Capacity was further expanded on 2015 and 2016 with addition of twin 3,000 L reactors and two 2,000 L single-use bioreactors.

In 2017, Rentschler forged a strategic Alliance with Munich-based formulation development specialist Leukocare AG.
