Bintrafusp Alfa and Doxorubicin Hydrochloride in Treating Patients With Advanced Sarcoma (TRUST)

Bintrafusp Alfa and Doxorubicin Hydrochloride in Treating Patients With Advanced Sarcoma. TRUST Study

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

Study Overview

• Status: Recruiting
• Conditions: Advanced Soft-tissue Sarcoma; Metastatic Soft-tissue Sarcoma
• Intervention / Treatment: Drug: Bintrafusp alfa; Drug: Doxorubicin

Detailed Description

This is a two multicenter, prospective, open-labeled, 2-arm, non-comparative randomized (2:1) phase II trials.

Patients satisfying eligibility criteria will first be stratified into 2 strata / subgroups:

• Soft-tissue sarcoma (STS) patients with an inflamed tumor (i.e. TLS+, defined as presence of mature tertiary lymphoid structures, as per IHC).
• Soft-tissue sarcoma patients with a cold tumor (i.e. TLS-, defined as absence of mature tertiary lymphoid structures, as per IHC).
• Note: TLS+ and TLS- account for 20% and 80% of STS patients, respectively.

STS patients with TLS+ will be randomized between arm A (bintrafusp alfa combined with doxorubicin for 6 cycles, followed by bintrafusp alfa maintenance) and arm B (doxorubicin for 6 cycles) with two patients randomized in arm A for one patient randomized in arm B.

STS patients with TLS- will be randomized between arm C (bintrafusp alfa combined with doxorubicin for 6 cycles, followed by bintrafusp alfa maintenance) and arm D (doxorubicin for 6 cycles) with two patients randomized in arm C for one patient randomized in arm D.
