About this study

Official title: A Dose-escalation and Phase IIa Study of TG6002 Plus Flucytosine in Patients With Unresectable Colorectal Cancer With Liver Metastases

This study will include two parts:

  • Phase I part is a dose-escalation study to assess the safety of increasing doses of TG6002 in combination with oral flucytosine (5-FC) in consecutive cohorts of 3 to 6 patients with colorectal cancer and unresectable liver metastases according to a 3+3 design
  • Phase IIa part is an extension of the phase I part at the recommended phase II dose to evaluate the efficacy of TG6002 in combination with oral flucytosine (5-FC) in patients with colorectal cancer and unresectable liver metastases.

In both parts, tumor response will be evaluated on local assessment using RECIST 1.1.

All patients will be followed until disease progression, death due to any cause or the date of data cut-off, whichever occurs first.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TG6002Biological

    Phase I part: Dose escalation from 1 x 10E6 PFU to 1 x 10E9 PFU. Phase II part: Established recommended Phase II dose (RP2D).

    Intrahepatic arterial (IHA) administration on Day 1 within a 14-day cycle of TG6002/5-FC combination treatment.

    A second cycle of TG6002/5-FC combination starting with TG6002 (IHA) administration at the same dose on Day43 can be initiated if no progressive disease or Dose Limiting Toxicity event in between; maximum 2 cycles of TG6002/5-FC combination treatment for each patient.

  • Flucytosine (5-FC)Drug

    Oral administration 4 times per day at the total dose of 200 mg/kg/day for 10 consecutive days per 14-day cycle of TG6002/5-FC combination.

    A second cycle of TG6002/5-FC combination will be initiated if no progressive disease or Dose Limiting Toxicity event in between.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Dose-limiting toxicities (Phase I part)

    Incidence of Adverse events using CTCAE v5.0

    Measured: Day 28

  2. Disease Control Rate (Phase II part)

    Proportion of patients whose tumour assessment is either complete response (CR), partial response (PR), or stable disease (SD)

    Measured: Week 10

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TG6002 and Flucytosine (5-FC) in people with Colorectal Neoplasms, run by Transgene at 3 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 23 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in France, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Study has been terminated after Phase I part on 23 February 2023). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose-limiting toxicities (Phase I part) (time frame: Day 28). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jun 2023; AzTrials last refreshed its copy on 8 Nov 2026.
