  • Histologically confirmed diagnosis of one of the following soft-tissue sarcoma subtypes: undifferentiated pleomorphic sarcoma (UPS) or dedifferentiated liposarcoma (DDLPS). Pathology review and/or confirmation by the French sarcoma reference pathology network (RRePS) or an equivalent expert sarcoma pathology review process is required whenever applicable according to national practice. [1,2]
  • Locally advanced/unresectable and/or metastatic disease not amenable to curative-intent surgery or curative-intent radiotherapy, as assessed by the Investigator in the context of multidisciplinary sarcoma management.

  • At least one measurable lesion according to RECIST v1.1. A measurable lesion must be accurately measurable in at least one dimension and have a longest diameter of ≥ 10 mm by CT scan or MRI, except for lymph nodes, which must have a short-axis diameter of ≥ 15 mm. Lesions located in a previously irradiated field may be considered measurable only if unequivocal progression has been documented after completion of radiotherapy. [21]

  • Eligible to receive doxorubicin-based first-line chemotherapy, including adequate cardiac function with left ventricular ejection fraction (LVEF) ≥ 50% by echocardiography or multigated acquisition scan (MUGA) performed during screening or within a period acceptable according to institutional practice, provided no intervening cardiac event has occurred.
  • Adequate hematologic and end-organ function, based on laboratory values obtained within 7 days prior to randomization unless otherwise specified.
  • Absolute neutrophil count (ANC) ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L, and hemoglobin ≥ 9 g/dL. Transfusion and/or growth factor support immediately before screening laboratory evaluation should be documented and should not be used to mask persistent inadequate bone marrow function.
  • Total bilirubin ≤ 1.5 x upper limit of normal (ULN), except for participants with Gilbert syndrome, for whom total bilirubin ≤ 3 x ULN is acceptable provided direct bilirubin is within normal range or clinically acceptable.
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 x ULN, or ≤ 5 x ULN in the presence of liver metastases.
  • Alkaline phosphatase ≤ 2.5 x ULN, or ≤ 5 x ULN in the presence of liver and/or bone involvement attributable to disease.

  • International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 x ULN and activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN, unless the participant is receiving anticoagulant therapy and coagulation parameters are within the expected therapeutic range for that treatment.
  • Adequate washout from prior anticancer therapy, if applicable: at least 5 half-lives or 28 days (whichever is longer) since the last dose of prior systemic chemotherapy or immunotherapy, and at least 2 weeks since the last radiotherapy or other local anticancer therapy, unless a shorter interval is clinically justified and approved by the Sponsor or Coordinating Investigator.

  • Patients shall be eligible to undergo IMP treatment and tumor biopsies. Patients who either do not consent to a tumor biopsy or do not have accessible lesions will not be eligible.
  • Availability of representative archival tumor material when feasible and willingness to allow its use for protocol-defined translational research. A fresh pretreatment biopsy is strongly recommended when clinically feasible and safe; refusal or inability to undergo a fresh biopsy should not preclude enrollment unless otherwise specified in the translational laboratory manual.
  • Willingness to provide protocol-defined blood samples for translational and pharmacodynamic research, including baseline and on-treatment samples, as specified in the schedule of assessments.
  • For women of childbearing potential *: negative serum or certified highly sensittive urine pregnancy test within 72 hours before the first dose of study treatment (In the event of a positive or uninterpretable urine result, a confirmatory serum pregnancy test must be performed immediately) and willingness to use highly effective contraception** during study treatment and after the last dose of study treatment for the period required by doxorubicin and DT-7012 risk management, i.e. at least 6 months after the last dose of doxorubicin and/or at least 6 months after the last dose of DT-7012, whichever is longer.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing DT-7012 and Doxorubicin in people with Undifferentiated Pleomorphic Sarcoma (UPS) and Dedifferentiated Liposarcoma (DDLPS), run by Gustave Roussy, Cancer Campus, Grand Paris at 1 site 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 27 inclusion and 25 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: opening soon, as of the sponsor's last update on 15 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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)1 42 11 42 11 line 34 71, antoine.italiano@gustaveroussy.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

6-month progression-free rate (PFR6) (time frame: from the enrollment to 24 weeks after treatment onset). 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 15 Sep 2026.
