Study Overview

Study of Safety and Tolerability of Intravenous CRS-207 in Adults With Selected Advanced Solid Tumors Who Have Failed or Who Are Not Candidates for Standard Treatment

This clinical trial will evaluate the safety and tolerability of CRS 207 an investigational product that is a weakened form (attenuated) of Listeria monocytogenes, a type of bacteria that is commonly found in the environment. CRS-207 has been altered in the lab to reduce its ability to cause disease, while maintaining stimulation of the immune system. CRS 207 has also been genetically modified with recombinant DNA to release an antigen called Mesothelin. Because CRS 207 stimulates an immune response to Mesothelin and Mesothelin may be present at higher levels on tumor cells than on normal cells, this clinical trial will also examine if CRS 207 boosts the immune system in a way that targets certain types of cancer. The purpose of this first clinical trial with CRS-207 is to identify an appropriate dose of the investigation agent for later clinical studies and to explore safety when given to consenting adults with advanced cancer of the ovary or pancreas, non-small cell lung cancer, or advanced malignant epithelial mesothelioma. Immunological response to CRS-207 and tumor status of study participants will also be measured. Patients who choose to enter the study must meet all study entry criteria and must have previously failed standard treatment for their cancer. Qualifying study patients will be assigned to receive one of several dose levels of CRS-207. Each patient may receive up to 4 intravenous administrations (21 days apart) of CRS-207 at their assigned dose level.

Patients who consent to participate in the study will be evaluated for eligibility according to their medical history, physical examination, blood testing, and computed tomography (CT) scan of thorax, abdomen, and pelvis. Those patients who qualify for the study will receive up to 4 intravenous doses of CRS-207, 21 days apart. After each infusion, they will be monitored overnight in an in-patient facility, including collection of blood specimens. Study participants will return after each infusion for outpatient follow-up visits for further blood tests and additional monitoring of safety and immune response to CRS-207. Participants will have repeat CT scans to measure tumor size after the 2nd dose and again after the 4th dose. On Day 91 participants will be discharged from the study. All study participants will be eligible to participate in a long-term follow-up study with a visit 6 months after the final dose of CRS-207 and annually thereafter for evaluation of disease progression, survival, and potential long-term toxicity of CRS 207.
