Outcomes

Primary Outcomes

Evaluation of Mucosal Staining Efficacy

Time Frame: One day- mucosal staining efficacy is assessed during the colonoscopy procedure

Mucosal staining efficacy of Methylene Blue MMX tablets after total oral doses of 150 or 200 mg. Methylene blue staining efficacy was assessed by scoring the observed percentage of staining as reported below for each colon region (AC, TC, DC, RES) 0 - no staining 1. - traces (poor traces in colon mucosa) 2. - detectable (at least the 25% of colon mucosa is stained) 3. - acceptable (at least the 50% of colon mucosa is stained) 4. - good (at least the 75% of colon mucosa is stained) 5. - over stained ( the 100% of the colon mucosa is over stained) After scoring (SC) separately each colonic segment, the total staining score (TSC) was also calculated and the number of regions with an SC\>2 (NSA) was determined. For each patient, the best effective TSC was set at 16, when SC=4 was detected in all 4 regions. SC=5 detected in any region and TSC\>16, both denoting an overstaining of the mucosa, were defined as suboptimal results in colon staining.

Secondary Outcomes

  • Safety and Tolerability of Methylene Blue MMX as Determined by AEs(Until study completion (until 2 days after dose))
  • Safety and Tolerability of Methylene Blue MMX as Determined by Heart Rate(until study completion (until 2 days after dose))
  • Safety and Tolerability of Methylene Blue MMX as Determined by Vital Signs (Oxygen Saturation in Peripheral Blood)(until study completion (until 2 days after dose))
  • Safety and Tolerability of Methylene Blue MMX as Determined Body Weight.(until study completion (until 2 days after dose))
  • Bowel Cleansing Quality-Boston Bowel Preparation Score(One day- bowel cleansing quality is assessed during the colonoscopy procedure)
  • Safety and Tolerability of Methylene Blue MMX as Determined by Vital Signs (Blood Pressure)(until study completion (until 2 days after dose))
