Pfizer Selects MMS as Preferred Provider for Plain Language Summary Writing Support

Pfizer has selected MMS Holdings Inc. (MMS), headquartered in Canton, MI, as a preferred provider for support writing plain language summaries of the results for all its Phase 2 and 3 clinical trials.

In advance of implementation of EU Clinical Trial Regulation No. 536/2014 (Article 37.4), Pfizer has committed to providing a plain language summary (PLS) of clinical trial results understandable to research participants in these clinical studies. This PLS initiative will bridge a gap between the patient community and the pharma industry, and reinforce Pfizer’s responsibility to the patients and patients’ families who help advance the drug development process. These summaries are currently being posted to Pfizer’s clinical trial site, and will be accessible in the EU, via the EU Portal and Database, when those are available. Partnering with MMS will ensure consistency in the way that trial result summaries are written and will help to improve comprehension for the study participants, patients and others.

According to Peggy Zorn who heads up the Transparency group at MMS, “We are pleased to support Pfizer with their plain language summary needs given our experience and understanding of the Transparency space. MMS has been a pioneer in this field, supporting clinical trial disclosures with TrialAssure™ for the past decade, anonymizing patient level datasets for use by researchers as a part of (CSDR) and was the first CRO to successfully complete preparation of regulatory document packages, including clinical trial reports, under the EMA Policy 0070 on publication of clinical data for medicinal products for human use. Our teams work seamlessly with Pfizer clinical and writing team members to ensure the highest quality of plain language summaries.”

“Pfizer is committed to ensuring clinical trial transparency requirements are met and that our study participants receive meaningful trial summaries. We are pleased to partner with MMS for the PLS initiative” said Dr. Sian Ratcliffe, Head of Medical Writing, at Pfizer.
