TOKYO, JAPAN - May 23, 2017 - Terumo Corporation (TSE: 4543) announced today that European Medicines Agency (EMA) has validated on May 18 for review the Marketing Authorization Application for a biosimilar to be formulated by Terumo. With this validation, the application is complete and the EMA will now begin the review procedure.

The primary container of the biosimilar is PLAJEX™, Terumo's polymer prefillable syringe. It is the first time that medicines filled in PLAJEX™ have been applied outside Japan.

Based on this achievement, Terumo will continue to expand its alliance business with pharmaceutical companies by taking advantage of material technology and aseptic filling technology of prefillable syringes.


PLAJEX™ is a sterile ready-to-fill polymer syringe developed by Terumo with a strong focus towards biopharmaceuticals. Key features of PLAJEX™ include:

  • a silicone oil-free prefilled syringe system for mitigating protein aggregation, integrating Terumo's proprietary i-coating™ plunger stopper*1.
  • steam sterilized for mitigating protein oxidation and aggregation*2.

About the biosimilar

The biosimilar is FKB327, an adalimumab biosimilar candidate of the fully human anti-TNF-α monoclonal antibody referencing Humira®. In October, 2016, FUJIFILM KYOWA KIRIN BIOLOGICS Co., Ltd. announced positive result in primary endpoint from Phase 3 global clinical study of FKB327.

Terumo has developed the biosimilar as a combination product that combines drug and device, collaborating with Fujifilm Kyowa Kirin Biologics and others. They adopted Terumo as a contract manufacturing organization.


FUJIFILM KYOWA KIRIN BIOLOGICS Co., Ltd. was established by FUJIFILM Corporation and Kyowa Hakko Kirin Co., Ltd. on March 27, 2012 as a company for developing, manufacturing, and marketing biosimilars.

    Silicone oil has been used as lubrication to achieve smooth plunger gliding functionality. However, in the context of biomolecules, silicone oil became a serious issue because it can induce protein aggregation. Terumo has developed a silicone oil-free prefillable polymer syringe system based on a plunger stopper combined with a specific coating technology, called i-coating™ providing smooth surface layer and consistent gliding forces over time.

    Earlier publications indicated that protein oxidation was induced in polymer prefillable syringes generated radicals by irradiation sterilization. On the other hand, no remarkable protein oxidation or radical generation was observed in steam-sterilized polymer prefillable syringe. Using steam sterilization as the sterilization method of PLAJEX™ may assist in mitigating interactions with the biopharmaceuticals by reducing the risks of protein oxidation.
