Endoscopy Publishes the Dayb Phase III Trial for Plenvu®(Ner1006), the First One Litre Peg Bowel Preparation[i]

Posted on: 25 Jul 18

AMSTERDAM, July 24, 2018 /PRNewswire/ --

PLENVU[® ]was as effective as sodium picosulfate and magnesium salt solution (CITRAFLEET[® ]) at achieving overall bowel cleansing success

PLENVU[® ]demonstrated non-inferior 'high quality' cleansing of the right colon 

PLENVU[® ]  showed superior overall bowel cleansing success and superior 'high quality' cleansing of the right colon in the per protocol population  

Visualisation of the ascending colon is important because adenomas and polyps in this area are often more difficult to see than those in other areas of the colon[ii] 

Norgine B.V. today announced that results from the PLENVU[® ] Phase III DAYB trial were published in ENDOSCOPY, a monthly peer-reviewed medical journal on behalf of the European Society of Gastrointestinal Endoscopy.

The DAYB study is a European study that compared PLENVU[® ] to a sodium picosulfate and magnesium salt solution using a 1-Day before split-dosing regimen in adults. The study met both primary endpoints.

PLENVU[® ]was as effective as sodium picosulfate and magnesium salt solution at achieving overall bowel cleansing success: 62% vs. 53.8%, P = 0.038 (LCL*: -0.5 %)

PLENVU[® ] demonstrated non-inferior 'high quality' cleansing of the right colon: 4.4% vs. 1.2%, P = 0.027, (LCL*: -5.6 %)

PLENVU[® ]showed superior overall bowel cleansing success: 68.0% vs. 57.5%, P = 0.023 and superior 'high quality' cleansing of the right colon 5.2% vs. 1.0%, P = 0.015, in the per protocol population.

Colonoscopy is an effective method for colorectal cancer screening and has been shown to reduce both the incidence and mortality of colorectal cancer when applied in the general population. Inadequate precolonoscopy bowel cleansing reduces the diagnostic accuracy of colonoscopy, particularly for the detection of smaller lesions and sessile polyps. This may result in repeat procedures, thereby increasing costs and potentially delaying the initiation of treatment, and potentially increasing resource requirement.[iii],[iv],[v]

PLENVU[® ] is approved in Europe and in the US. In Europe, PLENVU[® ] is available through Norgine and in the US through its partner Salix Pharmaceuticals, Ltd. ("Salix"), a wholly owned subsidiary of Valeant Pharmaceuticals International, Inc.

Norgine manufactures PLENVU[®] globally.
