feasibility of the lum imaging system for detection of prostate cancer

Conditions: Prostate Cancer; Neoplasm, Residual

Summary: the primary objective of this feasibility study is to determine if administration of lum015 will result in positive fluorescence of tumor tissue from ex vivo specimen imaging with the lum imaging device from patients undergoing radical prostatectomy for prostate cancer. both normal tissue and tumor tissue will be imaged and analyzed. the lum imaging system is a portable combination product consisting of an imaging device and an imaging agent (lum015). patients with an established diagnosis of prostate cancer and who are eligible for radical prostatectomy will be screened. eligible patients will be enrolled and on the day of their planned surgery, lum015 will be administered 2-6 hours prior to surgery. patients will undergo radical prostatectomy 2-6 hours after lum015 administration. all surgical specimens will be imaged with the lum imaging device and have routine diagnostic assessment. patients will be monitored for adverse events from time of injection through the first standard of care post-surgical follow-up visit.
