What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 80 participants in total. It began in 2022-03-01 with a primary completion date of 2027-01.

Brief Summary

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

Voluntarily signed and dated written informed consent prior to any study specific procedure, 16. Patients with a social security in compliance with the French law. Exclusion Criteria: 1. 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, 2. Known central nervous system malignancy (CNS), 3. 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, 4. Participation to a study involving a medical or therapeutic intervention in the last 30 days, 5. Previous enrolment in the present study, 6. Patient unable to follow and comply with the study procedures because of any geographical, social or psychological reasons, 7. Known hypersensitivity to any involved study drug or any of its formulation components, 8. Any history of anaphylaxis, or recent, within 5 months, history of uncontrollable asthma, 9. Individuals deprived of liberty or placed under legal guardianship, 10. Any of the following cardiac criteria: 1. Mean resting corrected QT interval (QTcF) ≥ 470 msec, obtained from three consecutive ECGs, 2. Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG, 3. LVEF ≤ 50% per CTCAE v5 by MUGA or echocardiogram 4. Any factors increasing the risk of QTc prolongation or arrhythmic events such as heart failure, hypokalaemia, potential for torsades de pointes, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years old or any concomitant medication known to prolong the QT interval, 5. Experience of any of the following procedures or conditions in the preceding 6 months: coronary artery bypass graft, angioplasty, vascular stent, myocardial infarction, unstable angina pectoris, uncontrolled hypertension, congestive heart failure NYHA Grade ≥2, ventricular arrhythmias requiring continuous therapy, supraventricular arrhythmias including atrial fibrillation, which are uncontrolled, haemorrhagic or thrombotic stroke, including transient ischaemic attacks, cerebral vascular accident/stroke or any other central nervous system bleeding 11. Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent: 12. History of bleeding diathesis or recent major bleeding event , 13. Prior organ transplantation including allogenic stem-cell transplantation, except transplants that do not require immunosuppression, 14. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection requiring systemic therapy, drug-induced interstitial lung disease or subject has had a history of drug-induced pneumonitis that has required oral or IV steroids, and/or other diseases, which in the opinion of the investigator might impair the subject's tolerance for the study or ability to consistently participate in study procedures, 15.
