E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this trial is to investigate whether the addition of 3 additional neo-adjuvant cycles of chemotherapy (doxorubicin and ifosfamide) to standard management according to the ISG-STS 10-01 study (3 cycles of neoadjuvant doxorubicin and ifosfamide 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). |
|
E.2.2 | Secondary objectives of the trial |
1· In high-risk CINSARC patients with resectable non-metastatic STS:
o Comparison of the two therapeutic strategies (6 cycles versus 3 cycles of neoadjuvant chemotherapy) in terms of additional efficacy outcomes:
- Loco-regional relapse-free survival (LR-RFS, after 3 years of follow-up),
- Progression-free survival (PFS, after 3 years of follow-up),
- Overall survival (OS, after 3 years of follow-up)
- Best overall response under treatment as per RECIST 1.1.
- Histological response (based on tumour samples)
o Comparison of the safety profile of the two therapeutic strategies.
o Translational research: Assessment of the prognostic and predictive values of treatment efficacy (PFS, M-PFS, LR-RFS and OS, after 3 years of follow-up) of gene expression profiling.
2· In low-risk CINSARC patients with resectable non-metastatic STS:
o Description of patients’ treatment
o PFS, M-PFS, LR-RFS and OS, after 3 years of follow-up. |

6. Age ≥ 18 years,
7. Life expectancy ≥ 3 months,

Patients must have measurable disease (lesion in previously irradiated field can be considered as measurable if progressive at inclusion according to RECIST 1.1) defined as per RECIST v1.1 with at least one lesion that can be measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm or ≥ 15mm in case of adenopathy,
10. Women of childbearing potential must have a negative serum pregnancy test before study entry. Both women and men must agree to use a medically acceptable method of contraception throughout the treatment period and for one year after discontinuation of treatment. Acceptable methods of contraception include intrauterine device (IUD), oral contraceptive, subdermal implant and double barrier. Subjects of childbearing potential are those who have not been surgically sterilized (e.g., vasectomy for males and hysterectomy for females) or have not been free from menses for ≥ 1 year,
11. Voluntarily signed and dated written informed consents prior to any study specific procedure,
12. Patients with a social security in compliance with the French law. |

E.4 | Principal exclusion criteria |
1. Soft-tissue sarcoma with the following histological subtypes: well-differentiated liposarcoma, alveolar soft-part sarcoma, dermatofibrosarcoma protuberans, clearcell sarcoma, embryonal and alveolar rhabdomyosarcoma,
2. Prior or concurrent malignant disease diagnosed or treated in the last 2 years except for adequately treated in situ carcinoma of the cervix, basal or squamous skin cell carcinoma, or in situ transitional bladder cell carcinoma,
3. Any other contraindication to anthracycline and Ifosfamide-based chemotherapy,
4. Participation to a study involving a medical or therapeutic intervention in the last 28 days,
5. Known infection with HIV, hepatitis B, or hepatitis C,
6. Females who are pregnant or breast-feeding,
7. Other medical conditions may interfere with the conduct of the study and, in the judgment of the investigator, would make the patient inappropriate for entry into this study,
8. Individuals deprived of liberty or placed under legal guardianship,
9. Unwillingness or inability to comply with the study protocol for any reason. |

E.5 End points |
E.5.1 | Primary end point(s) |
HIGH-RISK CINSARC PATIENTS:
Metastasis progression-free survival (M-PFS) is defined as the time interval between the randomization date and the date of death (whatever the cause), or distant progression, whichever occurs first (DATECAN guidelines, Bellera et al. Annals Oncol 2014).
LOW-RISK CINSARC PATIENTS:
M-PFS, LR-RFS, PFS and OS will be defined as the endpoints listed for high-risk CINSARC patients, with the exception of the starting date, which will be the date of diagnosis. These endpoints will be described after 3 years of follow-up. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After 3 years of follow-up. |
|
E.5.2 | Secondary end point(s) |
· Loco-regional relapse-free survival (LR-RFS) is defined as the time interval between the randomization date and the date of death (whatever the cause), or loco-regional progression, whichever occurs first (DATECAN guidelines, Bellera et al. Annals Oncol 2015). Progression-free survival is defined as the time interval between the randomization date and the date of death (whatever the cause) or progression (as per RECIST v1.1), whichever occurs first.
· Overall survival is defined as the time interval between the randomization date and the date of death (whatever the cause).
· Best overall response is defined as the best response recorded from randomization until the end of neoadjuvant chemotherapy taking into account any requirement for confirmation as per RECIST v1.1 criteria.
· Histological response is defined based on tumour sample as the average proportion of recognizable cells on the tumour sample [Huvos et al, Arch Pathol Lab Med 1977]. Good histological response is defined as <10% viable cells on the tumour sample.
· Safety will be described using the common toxicity criteria from the NCI v5. |
