Parenteral, Aseptic & Fill-Finish FAQs

Upperton’s Annex-1 aligned status, and unique operational structure means that we can get clients into the clinic in just 16 weeks, which is significantly quicker than the typical 12-18 months offered by competitors. 

Our aseptic offering features advanced VHP isolator technology, enabling aseptic filling of small-batch biopharma and small molecule products. We will also be bringing in aseptic spray drying capabilities in the near future. 

Annex-1 has significantly increased the standards for contamination control and quality. Our Annex-1 alignments ensures that the highest standards of quality and contamination control are upheld throughout every project we work with. 

Our sterile manufacturing services are specifically tailored to small to medium sized biotech companies. A large part of our offering involves providing small and mid-sized biotechs faster access to the high-quality sterile formulation development and manufacturing capacity they need to progress into clinical trials without unnecessary delays. This facility is a major part of that commitment.
