Summary:

      This study evaluates the efficacy, safety and tolerability of NER1006 versus Trisulfate
      Solution (TS) in adult patients requiring bowel cleansing prior to any procedure that
      requires a clean bowel, using a 2-Day evening/morning Split-Dosing regimen. Approximately 540
      patients will be randomised with the aim of achieving a minimum of 245 patients in each of
      the 2 groups.
