Macopharma announce the publication of the first European, Prospective, Non-Interventional Study, of THERAFLEX Methylene Blue Plasma

Tourcoing – March 29, 2017 — Macopharma today announced the publication of the manuscript related to the European prospective, non-interventional study, of THERAFLEX Methylene Blue Plasma, in Vox Sanguinis (DOI: 10.1111/vox.12510), which was carried out in collaboration with the SynteractHCR international CRO (Contract Research Organization), between May 2013 and April 2015.

The aim of this post-market surveillance study was to collect, during a period of at least one year, all adverse events that might be related to MB-treated plasma transfusions in seven key European hospitals of Belgium, United Kingdom (UK), Spain, and Greece, where MB-treated plasma is in routine use.

In this study, a total of 19,315 transfused units of MB plasma (3,780 transfusions for 3,005 recipients) were monitored. This number may be considered sufficiently robust to determine the safety of MB Plasma solidly. The incidence of serious Adverse Transfusion Reactions (ATRs) was 1 per 19,315 transfused units of MB plasma, which is similar to the incidence for untreated fresh frozen plasma reported by the French National Authority, ANSM. There were no ATRs reported in Greece where 9,241 units of MB plasma were transfused, nor in the UK where 434 units were transfused during the observation period.

“We are very pleased with the outcome of this trial; this prospective study confirms that Methylene Blue Plasma is a very safe product in routine use” Macopharma Medical Director Dr Ignacio Alvarez, said. “We are also very satisfied about the great collaboration we had with SynteractHCR.”
