Core competences

- Development and manufacturing of biopharmaceutical under GMP-conditions for clinical studies as well as for the market with focus on mammalian cell technology but also microbial cell technology – as contractor and for own R&D projects.
- Development and manufacturing of liposomal/LNP formulations under GMP conditions for clinical studies as well as for the market – as contractor and for own R&D projects.

Contract Services offered:

Contract Development and Manufacturing of Biopharmaceuticals
The core competence of Polymun is the development and GMP-compliant manufacture of biopharmaceuticals, using both mammalian and microbial cell technology. Polymun holds a pharmaceutical production license under paragraph 63 of the Austrian Pharmaceutical Law, thus fulfilling all EU regulations, and is inspected by FDA and regulatory authorities of other countries. Polymun offers all steps from the gene to clinical grade material for innovator and generic products. Polymun has gathered experience in designing purification processes for proteins of all kinds - antibodies, protein hormones and enzymes. A wide range of analytical methods is available that can be readily adapted to new requirements. GMP compliance and industrial applicability are central to all operations. Contract manufacturing includes the preparation of IMPD and CMC documents. Based on our own experience we are able to support planning of phase I-III clinical trials. As small, independent and private company Polymun has no conflict of interests thus granting a high degree of flexibility and security for its clients including the possibility of technology transfer.
Mammalian cell culture:

Stirred tank

- batch, fed-batch: 1x 15 L (seed bioreactor), 1x 250 L, 1x 450 L, 2x 2500 L
- perfusion: 1x 15 L (seed bioreactor), 1x 100 L

Disposable bioreactor

- 1x 25 L (WAVE, GE Healthcare)

Downstream purification:

- Process systems up to 600 L/h and 6 bar

Contract Development and Manufacturing of Liposomal/LNP Formulations
Liposomes protect, transport and release your drug at the right place and time. By this, a reduced dose achieves better efficacy and avoids side effects by a non-invasive application. Polymun offers the development of liposomal formulations for all kinds of active pharmaceutical ingredients and vaccine antigens. We manufacture GMP material including all necessary documentation and assist in planning of clinical trials. License agreements for Polymun’s patented liposome production technology are offered for the respective substance on an exclusive basis. Contracts can be arranged step by step - proof of concept, in-depth analysis, GMP-material production, product license - or all in one. Industrial applicability is the focus throughout each project. Polymun’s technology enables the industrial realization of pharmaceutical products for liposomal/LNP drug formats. The production technology is suitable for a broad range of substances formulated by passive entrapment, active loading or membrane incorporation.
Main characteristics of our technology are:
- Scalability
- Sterility
- Homogeneous, uniform vesicles
- Entrapment of several product classes with high efficiency
- Batch to batch consistency
- Stability due to a mild procedure

Own R&D Projects:

Porcine Recombinant Trypsin
Polymun has developted a proprietary recombinant porcine trypsin production system that is autocatalytically activated to the active enzyme. This product is used to replace trypsin of animal origin. It has defined activity (e.g. free of chymotrypsin activity without inhibitor treatment) and is free of tissue born contaminants.
Polymun has signed a license agreement with Laurus Bio Pvt Ltd (Bangalore, India) for the recombinant porcine trypsin technology. Richcore is manufacturing this recombinant porcine trypsin in large scale kilogram quantities for use in GMP processes.
