Unilife Unveils Unifill Multiple-Chamber Prefilled Syringes

Unilife Corporation announced the development and patenting of the Unifill EZMix multiple-chamber ready-to-fill syringe. In addition to being the world’s first and only dual or multi-chamber prefilled syringes with automatic (passive) safety features fully integrated within the glass barrel, the Unifill EZMix syringe offers minimal steps of use for healthcare workers and patients alike, the company said in a statement.
 
The syringes feature two or more primary drug containers within a single glass barrel to store a combination of liquid stable or lyophilized drugs along with up to 1mL of diluent for reconstitution.
 
The end-user advances the plunger to mix the lyophilized powder with the diluent, before swirling the device to complete reconstitution.  An audible, tactile click signals the injection of the full dose and the activation of a passive safety system that allows operators to control the speed of needle retraction directly from the body into the barrel.
 
Unifill EZMix syringes were developed in response to pharmaceutical companies seeking an innovative and convenient delivery system for the reconstitution and administration of lyophilized drugs and vaccines, the company said.
 
The syringe will be available with either a fixed (staked) needle for drugs indicated for subcutaneous injections, or with attachable needles of up to 1.5 inches in length.
 
Unilife CEO, Alan Shortall, said, “Unifill EZMix syringes are designed to address the unmet needs of pharmaceutical and biotechnology companies active within the large, fast-growing market for lyophilized drugs and vaccines. Nearly a third of all novel drugs approved by the FDA in the last three years were lyophilized, either because a drug’s large molecular composition made it unsuitable for liquid stable form or a pharmaceutical company wanted to fast-track the time to market.
 
“With the development pipelines of many pharmaceutical companies teeming with complex biologics that must be reconstituted at the point of delivery, we expect the market for lyophilized drugs and vaccines to experience double-digit growth for the foreseeable future. In addition, there are dozens of approved drugs requiring reconstitution that are approaching patent expiration and coming under increased pressure from brand-name, biosimilar or generic competition.
 
“Pharmaceutical companies recognize that innovative, convenient devices can help enhance therapy compliance, improve patient care and generate powerful brand differentiation within competitive therapeutic classes, therefore enabling them to increase market share and revenue. However, until now, there has never been a fully integrated delivery system that combines convenient drug reconstitution, intuitive use by the operator and optimal protection from needlestick injuries. Our Unifill EZMix syringes bring these distinct market needs together in one elegant and highly effective drug delivery system,” concluded Mr. Shortall.
