Norgine B.V. today presented new post-hoc analyses from the phase III DAYB and MORA studies that demonstrate the high-quality cleansing efficacy of PLENVU^®, a low volume, 1 litre PEG and ascorbate bowel preparation when compared to sodium picosulfate with magnesium citrate (CITRAFLEET^®) and 2 litre PEG with ascorbate (MOVIPREP^®) respectively when using site colonoscopist assessments.^[1],[2] In addition, data from the DAYB study show that PLENVU^® achieved statistically significant improvements in adequate cleansing rates using the Boston Bowel Preparation Score when compared to sodium picosulfate with magnesium citrate.^[3]

High cleansing efficacy:

• In the DAYB study, when compared to sodium picosulfate with magnesium citrate (CITRAFLEET^®) using a day before dosing, PLENVU^® achieved significantly better cleansing success;
  • in the overall colon (73.3% vs 60.9%, P=0.003)^[1]
  • and a high-quality cleansing of the ascending colon (36.3% vs 15.4%, P<0.001)^[1]
• In the MORA study, when compared to standard 2 litre PEG with ascorbate (MOVIPREP^®), PLENVU^® achieved a significantly improved rate of;
  • cleansing in the overall colon when administered as an evening/morning split-dose (97.0% vs 90.9%, P=0.003)^[2]
  • high-quality cleansing in the ascending colon when administered as an overnight split-dose (74.8% vs 60.9%, P<0.001) or morning-only dose (75.8% vs 60.9%, P<0.001)^[2]

Improved cleansing (Boston Bowel Preparation Scale) in evening only dosing when compared to sodium picosulfate with magnesium citrate;

• PLENVU^® achieved a statistically significantly increased proportion of adequate level cleansing of the overall (61.9% vs 47.3%, P=0.001) and ascending colon (66.9% vs 50.2%, P<0.001) in patients with Boston Bowel Preparation Scale scores^[3]

PLENVU^® has been shown to be well tolerated in studies versus standard 2 litre PEG with ascorbate, sodium picosulfate with magnesium citrate and trisulfate solution.^[4],[5],[6]

Dr Alastair Benbow, Chief Development & Medical Officer, Norgine commented "These phase III data confirm the potential of PLENVU^®, a low volume bowel preparation to replace standard bowel preparations. As colonoscopy is considered one of the most effective colorectal screening procedures, use of a highly efficacious bowel preparation such as PLENVU^® is important to enable better detection of adenomas and polyps which ultimately will improve patients outcomes and save healthcare systems resources."

These data were presented at Digestive Diseases Week, 6-9 May 2017, Chicago.

The PLENVU^® Phase III clinical trial programme includes three multicentre, randomised, parallel group studies: NOCT, MORA, and DAYB.

Colorectal cancer is the second most common cause of cancer-related mortality in Europe and the US, with 412,000 new diagnoses of colorectal cancer every year in Europe and 136,115 in the US.^[7],[8]

In August 2016, Norgine entered into a licensing agreement with Valeant Pharmaceuticals for PLENVU^® in the US and Canada.

PLENVU^® is not yet approved for use in the US or Europe. Norgine anticipates regulatory approval in Europe in 2017 and in 2018 in the US.
