Design outcomes

Primary

MeasureTime frame
Main Objective: Phase I: determination of the recommended phase II dose Phase IIa: efficacy of multiple administrations of TG6002 in combination with flucytosine (or Ancotil or 5-FC);Secondary Objective: Phase I: safety and tolerability, efficacy according to RECIST 1.1, TG6002 blood pharmacokinetics, 5-FC, 5-FU and FBAL blood concentrations, detection of neutralizing anti-vaccinia virus antibodies, TG6002 viral shedding in saliva, urine and feces. Phase IIa: safety, evolution of various tumor marker blood levels over time, TG6002 blood pharmacokinetics, 5-FC, 5-FU and FBAL blood concentrations, detection of neutralizing anti-vaccinia virus antibodies, biodistribution of TG6002 and 5-FC, 5-FU and FBAL concentration in liver metastasis biopsies (in a subgroup of patients with colon cancer and biopsiable liver metastases) and assessment of potential predictive or prognostic biomarkers.;Primary end point(s): Phase I: adverse events, serious adverse events, change in standard laboratory parameters and vital signs, dose-limiting toxicities. Phase IIa: overall response rate.;Timepoint(s) of evaluation of this end point: Phase I: days 1, 2, 7 or 8, 14 or 15, 16, 29, 57, 85 and then every 8 weeks. Phase IIa: days 43 and 85 and then every 8 weeks.
