About this study

Official title: Phase III Trial Investigating the Potential Benefit of Intensified Peri-operative Chemotherapy With in High-risk CINSARC Patients With Resectable Soft-tissue SARComas

The primary objective of this trial is to investigate whether the addition of 3 additional neo-adjuvant cycles of chemotherapy (doxorubicin based chemotherapy) to standard management according to the ISG-STS 10-01 study (3 cycles of neoadjuvant doxorubicin based chemotherapy + surgery +/- radiotherapy) improves the outcome of high-risk CINSARC patients with resectable soft-tissue sarcoma (STS). Primary endpoint is metastatic progression-free survival (M-PFS, after 3 years of follow-up).

Read the detailed description

For high-risk CINSARC patients, this is a multicenter randomized two-arm phase III trial, with a ratio 1:1:

  • Arm A: standard management (3 cycles of neoadjuvant doxorubicin based chemotherapy + surgery +/- radiotherapy)
  • Arm B: experimental arm (6 cycles of neoadjuvant doxorubicin based chemotherapy + surgery +/- radiotherapy)

For low-risk CINSARC patients, this a multicenter prospective cohort with treatment at the discretion of the investigator.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Doxorubicin, Ifosfamide or dacarbazine and At the discretion of the investigator in people with Non-metastatic Soft-tissue Sarcoma and Resectable, run by Institut Bergonié at 10 sites in France.

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 12 inclusion and 12 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: looking for participants now, as of the sponsor's last update on 2 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in France. 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Antoine ITALIANO, MD, PhD (+33 5.56.33.33.33, a.italiano@bordeaux.unicancer.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Metastasis progression-free survival in High-risk CINSARC patients (time frame: 3 years). 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 2 Oct 2025.
