Overview

From Drug Substance to Drug Product

Fill & Finish is the final step that turns a sterile bulk drug substance into a closed, inspectable and releasable drug product presentation.

53Biologics supports biologics programs that require aseptic filling into vials, bottles or single-use bags, as well as lyophilized presentations where product stability requires a solid sterile format.

What We Offer: A Range of Fill & Finish Possibilities

Aseptic Filling

Aseptic filling for sterile biologic drug products, with Grade A isolator technology and SciLog equipment to fill vials, bottles and single-use bags.

Lyophilized Drug Product

Lyophilization capability for products that require improved stability as a sterile solid presentation. Cycle transfer, execution and project-specific lyophilization support can be scoped according to product knowledge and regulatory stage.

Flexible Container Formats

Support for vials, bottles and single-use bags, including bulk filling where appropriate. We give each program the flexibility to match the final presentation to the product requirements and batch size.

QP Release and Storage

Batch documentation, release testing coordination and storage support from -80 °C to room temperature. QP release support can be included where applicable to the project scope.

Process

End-to-End Fill & Finish Capabilities

01

Aseptic Filling

Controlled filling of vials, bottles and single-use bags in a Grade A / ISO 5 isolator supported by SciLog liquid handling.

02

Lyophilization (Freeze-Drying)

Integrated freeze-drying for biologic drug products that require lyophilized final presentations to improve product stability, shelf-life or storage strategy.

03

Labelling & Packaging

Stoppering, crimping/capping and visual inspection to support batch completion, followed by secondary packaging activities when requested.

04

Storage

Full cold-chain logistics with controlled storage from deep-frozen to room-temperature conditions.

05

Release

Batch documentation and release support to help move the final drug product toward clinical, preclinical or selected commercial use.

Final Dosage Forms We Support

Dosage form Fill & Finish capabilities
Sterile liquid dosage forms Aseptic Filling of liquid drug product presentations under a controlled Grade A / ISO 5 isolator and SciLog system. Includes filling into vials, bottles and single-use bags, with appropriate closure systems and full batch documentation support.
Lyophilized sterile dosage forms Aseptic Filling followed by integrated lyophilization for drug products requiring freeze-dried final presentations. Supports stability-oriented dosage forms where the final product is supplied as a sterile lyophilized cake or powder for reconstitution.
Capsules Filling of capsule dosage forms under controlled conditions, supporting oral solid presentations where applicable. Includes encapsulation and packaging aligned with client requirements.

Frequently Asked Questions

Common questions about our aseptic Fill & Finish services. Can’t find what you need? Talk to our team.

Which dosage forms can 53Biologics manufacture?

We support aseptic filling of sterile liquid formulations and lyophilized products, with integrated freeze-drying capabilities for biologics requiring enhanced stability. Additional dosage forms may be evaluated depending on project requirements.

Which container formats do you support?

Our Fill & Finish platform supports sterile vials, bottles and single-use bags. Container closure systems are selected according to the product, filling volume and intended use.

Can you manufacture both Drug Substance and Drug Product?

Yes. We provide integrated Drug Substance manufacturing, aseptic Fill & Finish and analytical support under one roof, minimizing technology transfers and maintaining process knowledge throughout the project.

What types of biologics can you aseptically fill?

Our platform is suitable for a broad range of biologics, including plasmid DNA, vaccines, recombinant proteins like monoclonal antibodies, enzymes, and other sterile injectable products. Each project is evaluated individually to ensure compatibility with our manufacturing platform.

What batch sizes do you typically support?

Our semi-automated filling platform is designed for small- to medium-scale batches, making it particularly well suited for preclinical, clinical and orphan drug manufacturing, as well as niche commercial products.
