Laupheim, July 23, 2007


With the commissioning of two new GMP manufacturing suites, Rentschler Biotechnologie looks forward to completing the first phase expansion of its operations. Both systems will be used to produce therapeutic proteins and monoclonal antibodies.


The new fermenter lines with 500 L working volume each are sized such that, depending on the respective requirements, different cell culture processes can be run (batch, fed-batch, or perfusion). The ensuing protein purification is performed with state-of-the-art processes in two suites upstream and two suites downstream of the obligatory virus inactivation.


The first of two new 2,500 L multi-process fermentation suites is slated for commissioning in mid-2008. Both can optionally be used to run perfusion processes. The expansion project as a whole comprises a new laboratory building, a central energy station, a logistics space as well as additional  facilities for sterile filling of syringes and injection vials.


The global market for therapeutic proteins and monoclonal antibodies is growing continually. Demand for corresponding manufacturing capacity is rising in parallel. Besides allowing Rentschler to offer its customers development and manufacture of biopharmaceutical drugs for the phases of clinical trials, the company's expansion project launched in 2006 (REX = Rentschler expands) will also pave the way to future market supply of large output volumes of active pharmaceutical ingredients.


As a full-service contract manufacturing organization (CMO), Rentschler Biotechnologie now offers a total of eight stand-alone GMP suites (10 suites from mid-2008 on) to the market for process development on the smallest scale up to cGMP production in the 2,500 L range. Besides process development and production including formulation and fill & finish, add-on services such as assistance in drug registration and formulation development are being offered. This eliminates the need for costly and time-consuming technology transfer.
