Summary
Brief summary (as posted)
This clinical trial evaluated the safety and tolerability of CRS-100, an investigational agent containing a live-attenuated strain of Listeria monocytogenes (Lm). CRS-100 is attenuated by genetic modification to limit cell to cell spread and invasion of liver cells. These attenuations result in decreased virulence of CRS-100 in mice but retain the ability of the investigational agent to stimulate immunity in test animals and generate anti-tumor activity in mice. The primary objective of this study was to determine the maximum tolerated dose (MTD) and to explore the safety profile of a single intravenous dose of CRS-100 in consenting volunteers. Immunological response to CRS-100 and tumor status of study participants were also measured. Participation in this first clinical trial with CRS-100 was restricted to adults with carcinoma refractory to standard treatment (or for whom no standard treatment is available) and who additionally had liver metastases.
