Redefining Prefillable Syringe System

The West Synchrony™ S1 Prefillable Syringe (PFS) System is designed to take the complexity out of early drug product development by offering a more streamlined, system-level approach to getting to clinical fill faster. Rather than managing multiple disconnected components and testing pathways, the system brings everything together into a more cohesive framework that supports faster, more confident decision-making.

At the core of the approach are four key enablers: a single data verification package, compatibility assessments, aligned shipping formats, and system-level lot testing. Together, these are designed to reduce unnecessary duplication of work, minimise development friction, and help teams move more efficiently from concept to clinic.

To support a smoother development journey, materials are structured into a clear progression — from the Scouting Data Package and Onboarding Package through to the Verification Data Package and Regulatory Package. This step-by-step flow helps guide teams from early feasibility assessments all the way through to regulatory submission, with greater clarity at each stage.

Ultimately, the goal is simple: simplify system selection, reduce testing burden, and ensure consistent performance across the full syringe system — so teams can focus less on complexity and more on getting safe, effective therapies to patients sooner.
