Merck Introduces Eshmuno® P Anti-A and Anti-B Chromatography Resins for Enhancement of Plasma-Derived Immunoglobulin
  • Increased safety for patients undergoing immunoglobulin treatment
  • Excellent stability for longer product lifetime
  • Higher quality control with improved product release test

Darmstadt, Germany, September 20, 2017 Merck, a leading science and technology company, today launched Eshmuno® P anti-A and Eshmuno® P anti-B affinity chromatography resins specifically designed to remove anti-A and anti-B isoagglutinin antibodies during the manufacturing of plasma-derived immunoglobulin (Ig) therapies.

Trace amounts of anti-A and anti-B antibodies in plasma-derived Ig can lead to serious and sometimes fatal hemolytic events in patients undergoing plasma-based treatment. Introduction of chromatographic steps using Eshmuno® P resins to specifically deplete anti-A and anti-B antibodies is expected to reduce patient risk for adverse medical events associated with plasma-derived Ig therapies. This enhanced patient safety is achieved without negatively impacting process economics by reusing the resins for at least 200 cycles, with acid or alkaline cleaning, without loss of performance.

Eshmuno® P anti-A and Eshmuno® P anti-B resins are manufactured using a combination of Merck’s proprietary base matrix technology and a novel synthetic approach. The resins are released by an innovative test method to evaluate performance with significantly less variability compared with classical agglutination methods.

Merck has the right to grant non-exclusive sublicenses to certain patents and patent applications owned and controlled by LFB (Laboratoire français du Fractionnement et des Biotechnologies S.A.), strictly limited to the use of Eshmuno® P Anti-A and/or Eshmuno® P Anti-B resins for research, development and manufacture of plasma products (including toll and contract manufacturing for third parties). Customers who would like to purchase Eshmuno® P anti-A and/or Eshmuno® P anti-B resins from Merck will be provided further details regarding the availability of the foregoing sublicense.

Merck’s range of Eshmuno® and Fractogel® EMD chromatography resins are designed for efficient bioprocessing purification and are extensively used in commercial processes. These resins are well suited to support plasma purification processes, while minimizing operational costs and time to clinic.
