Primary Outcome Measures:
  • Determine the carcinoma- and adenoma lesion true detection rate [ Time Frame: Baseline ]

Enrollment: 13
Study Start Date: February 2009
Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Hexaminolevulinate Drug: hexaminolevulinate HCl
200mg hexaminolevulinate HCl capsule 6 hours before colonoscopy

Detailed Description:

Carcinoma of the lower GI-tract is among the leading malignancies in the western world causing a substantial morbidity, mortality and consequently a large burden to the health care system in the diagnosis, treatment and follow-up of these patients.

The primary objectives of this study is to determine carcinoma- and adenoma lesion true detection rate of HAL fluorescence colonoscopy in patients with known or strong suspicion of neoplasia in the colon. The secondary objective and endpoints are to determine carcinoma- and adenoma lesion false detection rate of HAL fluorescence colonoscopy, to compare carcinoma- and adenoma lesion true detection rates and the false detection rates of fluorescence with standard colonoscopy and to characterize the safety profile of HAL fluorescence colonoscopy.
