This study will include two parts:
- In the phase I part: safety will be assessed in consecutive cohorts of 3 to 6 patients at increasing doses of TG6002 in combination with oral flucytosine (5-FC) according to a 3+3 design in patients with advanced gastro-intestinal (GI) tumors.
- In the phase IIa part: evaluation of efficacy and further evaluation of safety of multiple administrations of TG6002 in combination with flucytosine (5-FC) in patients with colorectal cancer and liver metastases.
In both parts, tumor response will be evaluated on local assessment using RECIST 1.1.
All patients will be followed up until disease progression or death due to any cause or the date of data cut-off, whichever occurs first.

|Official Title:||A Phase I/IIa Study of TG6002 (VV TK-RR-FCU1) Administered by Intravenous (IV) Infusions in Combination With Oral Flucytosine (5-FC) in Patients With Advanced Gastro-intestinal (GI) Tumors.|
|Actual Study Start Date :||October 16, 2018|
|Estimated Primary Completion Date :||December 2020|
|Estimated Study Completion Date :||December 2021|
|Experimental: TG6002 and flucytosine combination||
Phase I: Dose escalation from 1 x 10E6 PFU to 1 x 10E9 PFU Phase II: Established recommended Phase II dose (RP2D)
Administration intravenously on Days 1, 8 and 15. An extension of the 28-day cycle of TG6002/5-FC combination can be repeated in case of evidence of patient benefit, defined as an objective radiological response or disease stabilization, and/or a clinically significant relief in patient's symptoms. Additional cycle(s) will start from 2 to 4 weeks following the last 5-FC intake.
Drug: Flucytosine (5-FC, Ancotil)
Administered orally at a dose of 200 mg/kg/day from Day 5 to 7, Day 12 to 14 and Day 19 to 28.
An extension of the 28-day cycle of TG6002/5-FC combination can be repeated in case of evidence of patient benefit, defined as an objective radiological response or disease stabilization, and/or a clinically significant relief in patient's symptoms. Additional cycle(s) will start from 2 to 4 weeks following the last 5-FC intake.
- Phase I part - Dose-limiting toxicities [ Time Frame: Day 28 ]Dose-limiting toxicities
- Phase II part - Overall response rate [ Time Frame: Day 43 ]Overall response rate according to Recist v1.1
