About this trial

This study encompasses two multicenter, prospective, open-labeled, 2-arm, non-comparative randomized phase II trials to assess the antitumor activity of bintrafusp alfa in association with doxorubicin

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Histologically confirmed soft-tissue sarcoma with unknown translocation (including the following histologies but not limited to undifferentiated pleomorphic sarcomas, dedifferentiated liposaromas or leiomyosarcomas). Diagnosis must be reviewed or confirmed by the RRePS Network (Réseau de référence en pathologie des sarcomes et des viscères) as recommended by the French NCI (Institut National du Cancer, Inca).

Metastatic or unresectable locally advanced disease,

No previous systemic treatment for advanced/metastatic disease,

For TLS status: available archived FFPE (Formalin-Fixed Paraffin-Embedded) tumor tissue sample or tumor material newly obtained by biopsy. Except if TLS analysis have been already performed by Biopathological platform at Bergonié Institute, presence or absence of TLS should be confirmed by central review based on FFPE tumor tissue sample (archived or newly obtained by biopsy for research purpose),

Disqualifiers

Previous treatment with doxorubicin, daunorubicin, epirubicin, idarubicin and/or any other anthracyclines or anthracediones at the maximum cumulative dose or any approved or investigational treatment targeting PD1, PD-L1 or TGFB1,

Known central nervous system malignancy (CNS),

Men or women of childbearing potential who are not using an effective method of contraception as previously described; women who are pregnant or breast feeding,

Participation to a study involving a medical or therapeutic intervention in the last 30 days,

Trial outcomes

Primary outcomes

1

Assessment of the antitumor activity of combined administration of standard doxorubicin and double immune modulation with Bintrafusp alfa in terms of 6-month progression-free rate, in STS patients with an inflammed tumor

Antitumor activity will be assessed in terms of 6-month progression-free rate and is defined as the rate of complete or partial response (CR, PR) or stable disease (SD), as per RECIST v1.1.

Time frame
6 months
2

Assessment of the antitumor activity of combined administration of standard doxorubicin and double immune modulation with Bintrafusp alfa in terms of 6-month progression-free rate, in STS patients with a cold tumor

Antitumor activity will be assessed in terms of 6-month progression-free rate and is defined as the rate of complete or partial response (CR, PR) or stable disease (SD), as per RECIST v1.1.

Time frame
6 months

Secondary outcomes

1

6-month objective response rate (ORR) independently for patients with an inflammed tumor

Objective response is defined as complete response (CR) or partial response (PR) as per adapted RECIST v1.1.

Time frame
6 months
2

6-month objective response rate (ORR) independently for patients with a cold tumor

Objective response is defined as complete response (CR) or partial response (PR) as per adapted RECIST v1.1.

Time frame
6 months
3

Best overall response for patients with an inflammed tumor

Best overall response is defined as the best reponse across all time points (RECIST v1.1). The best overall response rate is determined once all the data for the patient is known

Time frame
throughout the treatment period, an expected average of 6 months
4

Best overall response for patients with a cold tumor

Best overall response is defined as the best reponse across all time points (RECIST v1.1). The best overall response rate is determined once all the data for the patient is known

Time frame
throughout the treatment period, an expected average of 6 months

Other outcomes

1

Tumor immune cells levels independently for each population

Levels of immune cells (CD4, CD8, PDL1)in tumor will be measured by immunohistochemistry

Time frame
baseline, cycle 2 day 1, and progression (each cycle is 21 days)
2

Blood cytokines levels independently for each population

Levels of cytokines (tryptophane, interleukine) in blood will be measured by ELISA

Time frame
baseline, cycle 2 day 1, cycle 3 day 1 and progression (each cycle is 21 days)
3

Blood lymphocytes levels independently for each population

Levels of fixed PBMC (peripheral blood mononucear cells) in blood will be measured by flow cytometry

Time frame
baseline, cycle 2 day 1, cycle 3 day 1 and progression (each cycle is 21 days)
4

Blood kynurenine levels independently for each population

Levels of kynurenine in blood will be measured by ELISA

Time frame
baseline, cycle 2 day 1, cycle 3 day 1 and progression (each cycle is 21 days)
