Gore to debut GORE™ ImproJect™ plunger for sensitive biologics in pre-filled syringes

Posted: 16 February 2018 | | No comments yet

NEWARK, Del. – W.L. Gore & Associates, Inc. (“Gore”), a global materials science company, will introduce its new GORE™ ImproJect™ Plunger at Pharmapack 2018, Europe’s dedicated pharmaceutical packaging and drug delivery event. Gore will be in Booth A12 at the exhibition, to be held February 7 and 8, 2018, at the Paris Expo, Porte de Versailles…


Conventional plungers for pre-filled glass syringes are designed to work with lubricated barrels where silicone often acts as the lubricant between plunger and syringe during drug administration and provides a seal between plunger and syringe. However, silicone has been shown to potentially interact with sensitive biologics possibly leading to particulation and aggregation. Over time, the measurable migration of silicone can also cause changes in break and glide force, which may impact injection performance and affect patient comfort.  By eliminating silicone from the barrel and the plunger of a pre-filled syringe, the GORE™ ImproJect™ Plunger may enable today’s more challenging sensitive biologics to be administered in a pre-filled syringe, a practice that may  not have been an option with traditional siliconised pre-filled syringe systems. 

“Instead of working to stabilise the silicone or replace it with another lubricant, Gore has taken the completely new approach of eliminating silicone altogether in both plunger and glass barrel,” said John Holcombe, Business Leader for Drug Delivery & Packaging for Gore PharmBIO Products. “We look forward to introducing this technology to our colleagues at Pharmapack and speaking more about the potential benefits it holds for patients, care providers, and pharmaceutical formulation and packaging organisations.”
