Sterile fill-finish services

Efficiently complete the manufacturing process for your parenteral, injectable medicines

As a proven leader in the production of biologics and small molecules from first-in-human (FIH) trials to commercial-scale manufacturing, we can help you advance to market quicker. With many format and formulation choices available including lyophilized, we can manufacture the right format for every stage of the product lifecycle.

Flexible sterile fill-finish services at our cGMP facilities can accommodate a variety of molecules including biologics and mRNA. For preclinical work, non-cGMP options are also available. Our global teams and regulatory experts have guided numerous projects to successful NDA/BLA approval — we can do the same for you.

Aseptic fill-finish solutions for parenteral drug products

Work with a leading CDMO of parenteral/injectables to take your medicine from formulation through commercialization. Our teams can help at every phase of the product lifecycle, leveraging decades of experience to help you produce different parenteral drug formulations as your needs evolve.

Developing the correct formulation can be time-consuming when you can least afford delays. The chemical nature of the compound may present significant challenges like temperature and shear sensitivity, poor solubility, and high potency. Lyophilization, if desired, requires cycle optimization.

Our established parenteral formulation processes include:

1. Pre-formulation: Optimal pH, ionic strength, degradation pathways, and stability studies
2. Formulation development: Select and define optimal levels for all excipients using OFaT and/or design of experiments (DoE) approaches
3. Formulation confirmation: Confirm stability of the selected final formulation using analytical tools

Reduce costs and assure quality during preclinical and phase I studies

Preclinical and phase I studies can have lengthy timelines that lead to increased costs. Ensuring quality and consistency across processes in early development is critical as you move from phase to phase. Lyophilization, use of non-cGMP batches, and pre-qualified components can address both concerns. Lyophilization increases stability, leading to a longer shelf-life for the duration of clinical trials.

To save time and money, we offer non-cGMP suites that ensure scalable equipment. The setup of our non-cGMP lines mimics our cGMP lines — it’s the same material without the aseptic processing and costs associated with cGMP spaces.

Improve your chances of approval. Patheon pharma services can help you balance speed, regulatory needs, and the supply chain as you scale up. We offer the ability to:

  • Navigate a complex regulatory environment at a global scale
  • Get your product to market and patients quicker
  • Execute tech transfers with speed and efficiency
  • Ensure a robust supply chain within a global network

Our experienced regulatory teams have an enviable track record of drug commercialization success for our clients. Leverage our commercial production and clinical trial solutions to gain extensive access to global technical experts, capability, regulatory insights, and transportation.
