Norgine B.V. today presented new data at the United European Gastroenterology Week which show that for the first time, PLENVU® (polyethylene glycol 3350, sodium ascorbate, sodium sulfate, ascorbic acid, sodium chloride and potassium chloride for oral solution) delivers superior, high quality segmental cleansing efficacy compared to MOVIPREP®, SUPREP® and CitraFleet[®i].
This post hoc analysis compared the level of high-quality segmental cleansing attained by PLENVU® versus its comparators MOVIPREP® (2L PEG + Ascorbate), SUPREP® (Oral Sulfate Solution) and CitraFleet® (Sodium Picosulfate + Magnesium Citrate), using data from three Phase 3, multicentre, randomised trials: NOCT, MORA and DAYB.[ii],[iii],[iv]

FAS, Full Analysis Set. mFAS, modified Full Analysis Set (FAS excluding
patients who failed lab screening after randomisation and who also failed to
take their study treatment). Per-Protocol (FAS with fulfilled entry criteria,
who took greater than or equal to75% of both study preparation doses, had data
for at least one of the primary endpoints, and no major protocol deviations).
Prof. Alessandro Repici,. Humanitas Hospital, Milan, Italy said: "These new data are significant because they demonstrate that PLENVU® provides superior high-quality colon cleansing efficacy to commonly used alternatives. High quality cleansing is associated with higher lesion detection rates; therefore, patients should use a high quality bowel cleanser to facilitate early detection and removal of abnormalities in order to prevent colorectal cancer."
He added: "By reducing the amount of bowel preparation volume, PLENVU® may improve patient experience and adherence to bowel cleansing instructions. Improved adherence to bowel preparation is known to reduce the need for repeat colonoscopy procedures, thereby reducing healthcare costs."
Colorectal cancer is the second most common cause of cancer-related mortality in Europe, with over 447,000 new diagnoses every year.[v] Colorectal cancer is largely preventable, with early detection being associated with a 90% cure rate.[vi]
PLENVU® is available in Austria, Australia, Belgium, Denmark, Finland, Germany, Ireland, Italy, The Netherlands, Norway, Portugal, Spain and the UK via Norgine and in the US via its partner Salix Pharmaceuticals. Norgine is anticipating further launches in 2018.
