Treatment of Metastatic Soft Tissue Sarcoma (STS) Patients (FIBROSARC USA)

Overview

  • Study type

    Interventional
  • Study phase

    II/III
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The present study is an open-label, randomized, controlled, two-arm multi-center study of the efficacy of L19TNF treatment in combination with doxorubicin versus doxorubicin alone in metastatic or unresectable soft-tissue sarcoma patients. In the study, 114 patients will be randomized in a 1:1 ratio to receive doxorubicin treatment (Arm 1) or L19TNF treatment in combination with doxorubicin (Arm 2). The primary objective of the trial is to evaluate if L19TNF in combination with doxorubicin (Arm 2) given for unresectable or metastatic soft tissue sarcoma improves efficacy measured as progression free survival, as compared to doxorubicin alone (Arm 1). Anti-cancer activity will be assessed every 6 weeks during therapy and every 12 weeks thereafter.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  1. Age 16 - 85 years. Patients under 18 years, should be fully grown (prove of fused growth plates).
  2. Patients with histological evidence of advanced unresectable and/or metastatic high-gradesoft tissue sarcoma (grade 2 - 3 according to the FNLCC grading system) not amenable to curative treatment with surgery or radiotherapy.
    • The following tumor types are included:
      • Malignant fibrous histiocytoma (undifferentiated pleomorphic sarcoma)
      • Myxoid and round cell liposarcoma, pleomorphic liposarcoma or dedifferentiated liposarcoma
      • Myxofibrosarcoma intermediate and high-grade
      • Fibrosarcoma
      • Leiomyosarcoma
      • Angiosarcoma
      • Unclassified sarcoma NOS
    • The following tumor types will not be included:
      • GIST
      • Mixed mesodermal tumor
      • Synovial sarcoma
      • Malignant peripheral nerve sheath tumor
      • Epithelioid sarcoma
      • Embryonal rhabdomyosarcoma
      • Chondrosarcoma
      • Malignant mesothelioma
      • Neuroblastoma
      • Osteosarcoma
      • Ewing's sarcoma / primitive neuroectodermal tumor
      • Desmoplastic small round cell tumor
      • Alveolar soft part sarcoma
      • Pleomorphic rhabdomyosarcoma
      • Alveolar rhabdomyosarcoma
  3. Patients must have at least one unidimensionally measurable lesion by computed tomography as defined by RECIST criteria 1.1. If only 1 lesion is present at screening, this lesion should not have been irradiated during previous treatments.
  4. Life expectancy of at least 3 months in the judgment of the investigator.
  5. ECOG ≤ 2.
  6. Documented negative test for HIV-HBV-HCV. For HBV serology: the determination of HBsAg, anti-HBsAg-Ab and anti-HBcAg-Ab is required. In patients with serology documenting previous exposure to HBV (i.e., anti-HBs Ab with no history of vaccination and/or anti-HBc Ab), negative serum HBV-DNA is required. For HCV: HCV-RNA or HCV antibody test. Subjects with a positive test for HCV antibody but no detection of HCV-RNA indicating no current infection are eligible.
  7. Female patients: negative serum pregnancy test for women of childbearing potential (WOCBP)* within 14 days of starting treatment. WOCBP must agree to use, from the screening to six months following the last study drug administration, highly effective contraception methods, as defined by the "Recommendations for contraception and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies' ClinicalTrial Facilitation Group (www.hma.eu/ctfg.html) and which include, for instance, progesterone-only or combined (estrogen- and progesterone-containing) hormonal contraception associated with inhibition of ovulation, intrauterine devices, intrauterine hormone-releasing systems, bilateral tubal occlusion, vasectomized partner or sexual abstinence.
    Male patients: Male subjects able to father children must agree to use two acceptable methods of contraception throughout the study (e.g. condom with spermicidal gel). Double-barrier contraception is required.
    * Women of childbearing potential are defined as females who have experienced menarche, are not postmenopausal (12 months with no menses without an alternative medical cause) and are not permanently sterilized (e.g., tubal occlusion, hysterectomy, bilateral oophorectomy or bilateral salpingectomy).
  8. Informed consent signed and dated to participate in the study.
  9. Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures.
     

Exclusion Criteria:

  1. Prior therapy (except surgery and radiation) for unresectable or metastatic malignant soft tissue sarcoma.

  10. Heart insufficiency (> Grade II, New York Heart Association (NYHA) criteria).
  11. Clinically significant cardiac arrhythmias or requiring permanent medication.
  12. Abnormalities observed during baseline ECG and Echocardiogram investigations that are considered as clinically significant by the investigator. Subjects with current, or a history of QT/QTc prolongation would be excluded. In particular:

    • patients with a marked prolongation of QT/QTc interval (e.g., repeated demonstration of QTc >480 milliseconds using Fredricia's QT correction formula) are excluded;
    • patients with a history of risk factors for Torsades de Pointes (e.g., heart failure, hypokalemia, family history of prolonged QT syndrome) are excluded;
    • patients who require the use of concomitant medications that prolong the QT/QTc interval are excluded.
  13. Uncontrolled hypertension, despite optimal therapy.
  14. Ischemic peripheral vascular disease (Grade IIb-IV according to Leriche-Fontaine classification).
  15. Severe diabetic retinopathy such as severe non-proliferative retinopathy and proliferative retinopathy.
