KEY TOPICS COVERED
Market drivers and the IV-to-SC transition
The webinar opens with an analysis of the primary drivers accelerating the shift from IV to subcutaneous administration: patient comfort, improved adherence, and measurable cost savings for healthcare systems managing chronic biologic therapies. Large-volume SC delivery addresses a critical gap between clinic-bound IV infusion and the convenience of home self-injection.
Primary packaging requirements for large-volume SC systems
Plunger seals for sensitive biologics in large-volume SC systems must meet stringent requirements across extractables and leachables, container closure integrity, particulate control, silicone management, and device compatibility. For wearable injectors, consistent break-loose and glide force performance across storage conditions is not a secondary consideration — it is a device actuation requirement.
NeoFlex™ plunger portfolio for large-volume cartridge formats
Datwyler's expanded NeoFlex™ plunger portfolio covers 5mL, 10mL, and 20mL pharmaceutical cartridge formats, aligned to ISO 13926-1 standards. The V9621 extends proven NeoFlex™ performance to the 20mL format, building on the commercial 10mL platform.
Collaborative case study: 20mL on-body injection system
The webinar presents a collaborative case study combining Datwyler's V9621 NeoFlex™ plunger, Stevanato Group's EZ-fill® 20mL pharmaceutical cartridge, LTS Device Technologies' Sorrel™ wearable platform, and Grand River Aseptic Manufacturing for fill-finish. One-month stability data demonstrates break-loose forces compatible with the Sorrel™ device vacuum limits, stable glide forces at both 5–8°C and 20°C storage, dose accuracy within ±5% across all configurations, and hold-up volume minimization through cone plunger geometry. This extends Datwyler's proven plunger performance across format types, building on the company's broader portfolio for pharmaceutical cartridges.
