PREFILLABLE SYRINGE SYSTEM - Beyond Components: Designing Prefillable Syringe Systems to Streamline Success


Key Points

  • When your PFS system is designed and owned by the same supplier, you can refer to a single Design & Development File. This approach simplifies the regula­tory process, improves submission effi­ciency, and accelerates global market access.

INTRODUCTION

The self-administered biologic market is expected to reach $146.0685 billion by 2034.1 Delivery devices, such as prefilled syringes, autoinjectors, and pen injectors, have been significant catalysts for the expected growth in subcutaneous, self-adminis­tered biologics. Notably, prefilled syringes have emerged as a cornerstone technology, with industry reports estimating that more than 60% of biologics are delivered via these devices.2 Addition­ally, prefilled syringes for vaccine administration will undoubtedly play a vital role in the efficiency and scalability of future immu­nization campaigns.

And yet, development teams are still taking component-based approaches to building their prefillable syringe (PFS) sys­tems that frankly will not meet the needs of a fast-paced and ever-evolving market. What’s needed is a shake up that can ad­dress PFS performance, regulatory, and supply challenges that plague pharmaceutical manufacturers in early phases of devel­opment.

West Synchrony™ S1 PFS system provides a broad product portfolio including 1 ml long and 2.25 ml staked needle options for biologics and 1 ml standard staked needle and Luer lock options for vaccines.

YOU CAN’T BUILD A PFS SYSTEM OUT OF COMPONENTS

Typically, pharmaceutical manufacturers must source primary PFS components (syringe barrel, needle shield or tip cap, and sy­ringe plunger) from multiple suppliers. This can result in down­stream issues that may not be visible from the component level at the outset, but can show up later as delays, rework, and reg­ulatory inquiries.

Often, companies must spend sacred time and money com­piling component-level data sets to generate system-level per­formance data for their selected device. With multiple component suppliers, procurement teams are left to combat mismatched order quantities and massive lead times to optimize supply for clinical trials and commercial inventory.

When it’s time for regulatory submission, and regulators or notified bodies inevitably come back with questions on how the assembled PFS performs, 3-way CDAs and finger pointing ensues in a fruitless quest for answers.

Sound familiar? You can stop building your PFS from com­ponents and instead opt for an integrated, verified prefillable sy­ringe system.

Staked needle system options come with either a rigid or soft needle shield and Luer lock system options will have an integrated tip cap.

UNLOCK SYSTEM-LEVEL PERFORMANCE DATA

True transparency means having ac­cess to consolidated performance data for the entire PFS system, not just individual components from various suppliers. Frag­mented data increases complexity, regula­tory uncertainty, and risk. West has transformed this landscape with its pre-generated verification data package — uniquely available with the West Synchrony™ S1 prefillable syringe (PFS) system.

Robust, system-level data ensures all necessary testing has been completed for the platform, independent of the molecule. Thus, pharmaceutical companies remain shielded from the pitfalls of fragmented component-level data, which traditionally requires extensive effort to synthesize into a holistic approach.

STREAMLINE REGULATORY SUBMISSIONS WITH ONE ACCOUNTABLE SOURCE

Combination products face intricate regulatory landscapes, especially when navigating global compliance. All too often, companies are underprepared with fragmented data when it comes time for their regulatory submission. They ask mul­tiple component suppliers for documenta­tion, and what they get back is in various formats and different levels of visibility.

When your PFS system is designed and owned by the same supplier, you can refer to a single Design & Development File. This approach simplifies the regula­tory process, improves submission effi­ciency, and accelerates global market access.

As the sole developer and owner of the West Synchrony S1 PFS system, West has created one DMF with the US FDA, Health Canada, and China that encom­passes the entire syringe system. Addition­ally, all necessary data needed for your technical file to be submitted to notified bodies in Europe is readily available in one regulatory package included in the system offering.

SIMPLIFY PFS PROCUREMENT & SUPPLY

Development timelines often suffer due to supplier coordination and variable component availability. Relying on a sin­gle, verified PFS system streamlines pro­curement and supply chain management. With one accountable supplier, you can re­duce lead time variability, minimize delays, and enable quicker responses to change, helping you meet critical milestones.

Every lot of the West Synchrony S1 PFS system produced undergoes rigorous sys­tem-level batch testing, ensuring that de­vice constituent part integrity and perform­ance are verified before incoming inspections.

The system also includes high performance West NovaPure® and FluroTec™ barrier film plungers.

BEST PRACTICES FOR PFS SYSTEM STRATEGY

West has been helping pharmaceuti­cal manufacturers bring life-saving thera­pies to patients for more than 100 years. Best practices have accumulated along the way that have informed the design and development of the West Synchrony S1 PFS system. When scouting PFS options, com­panies need to consider:

Starting Early: Most R&D groups begin drug trials in vials, understandably, be­cause vials are variable when it comes to injection volume. However, when that drug candidate has proven itself and it’s time to transition into a prefillable syringe, the submission timeline gets tight. Developing a device can take many months up to a few years and should not be started too late in your process. Otherwise, you risk missing important tests and/or not creat­ing the necessary scientific depth of data as required by regulatory agencies.

Having a Proactive Approach to Supply: Tie technical configuration to realistic, phase-appropriate supply frameworks. PFS supply elements, such as lead times, order quantities, and scalability, should align with clinical and commercial plans to ensure cost-efficient, reliable supply.

Embedding the Regulatory Strategy: Treat regulatory documentation as an in­tegral part of the system design, not an af­terthought. With system-level regulatory documentation at the ready, you can sup­port timely submissions.

FROM COMPONENTS TO SYSTEMS: A PARADIGM SHIFT

Prefillable syringes for biologics and vaccines can no longer be assembled as a set of parts; they must be treated as en­gineered systems with data, supply, and regulatory strategies built in from the start.

The West Synchrony S1 PFS system embodies this system-level approach. By choosing an integrated, verified system, emerging biotechnology and pharma teams can align with the best practices outlined in this article and be on their way to their clinical fill faster equipped with sys­tem-level performance data for their de­vice constituent part, an embedded regulatory strategy, and simplified supply.
