简要总结
This is an open-label, dose escalation and dose expansion, multi-center phase I study evaluating the safety and tolerability of CF33-CD19 administered intravenously (IV) or intratumorally (IT) in combination with blinatumomab and with or without hydroxyurea in adults with advanced or metastatic solid tumors.
详细描述
CF33-CD19, a novel chimeric orthopoxvirus, will be administered as a monotherapy or in combination with blinatumomab and with or without hydroxyurea to assess the safety and efficacy of the treatment regimens as well as immunological changes in the tumour microenvironment. Subjects eligible for treatment include those with any metastatic or advanced solid tumor who have documented radiological progression per RECIST following at least two prior lines of therapy. All enrolled monotherapy subjects will be treated with CF33-CD19 on Day 1 and 8 of Cycle 1 and then on Day 1 of each 21-day cycle thereafter. Subjects treated with the combination regimen will receive CF33-CD19 on Days 1 and 15 of each 28-day cycle. In addition, they will receive blinatumomab as a 7-day continuous infusion from Days 2-9 and Days 16-23 of each cycle.
