- Conditions
- Soft Tissue Sarcoma
- Interventions
- Registration Number
- NCT04733183
- Lead Sponsor
- Philogen S.p.A.
- Brief Summary
Open label, randomized, controlled phase II study preceded by a safety run-in part in subjects with advanced or metastatic soft-tissue sarcoma.
- Detailed Description
Open label, randomized, controlled phase II study preceded by a safety run-in part in subjects with advanced or metastatic soft-tissue sarcoma.
* Safety Run-in Part: Six (6) patients will be treated with 1000 mg/m2 dacarbazine (DTIC) on Day 1 every 3 weeks plus 13 µg/kg L19TNF on Days 1, 3 and 5 every 3 weeks to test for safety of the combination. Should unacceptable toxicities occur in ≥ 2 patients during an observation period from Day 1 to Day 21 (first cycle), enrollment will be stopped at this dose level and 6 patients will be treated sequentially with DTIC at 850 mg/m2 on Day 1 every 3 weeks plus 13 µg/kg L19TNF on Days 1, 3 and 5 every 3 weeks.
* Tumor Activity Evaluation Part
Approximately 86 patients will be enrolled and parallel assigned in a 1:1 fashion to one of two different arms, as follows:
* Arm 1: Patients will receive DTIC on Day 1 every 3 weeks plus L19TNF on Days 1, 3 and 5 every 3 weeks.
* Arm 2: Patients will receive DTIC on Day 1 every 3 weeks. During the conduct of the study, detailed safety parameters will be routinely reviewed by the DSMB.
Recruitment & Eligibility
- Status
- ACTIVE_NOT_RECRUITING
- Sex
- All
- Target Recruitment
- 98
-
Male or female, 18 to 80 years of age.
-
Histologically or cytologically confirmed advanced unresectable or metastatic soft tissue sarcoma (STS), Grade 2 - 3 according to the FNLCC grading system. Participants with bone sarcomas including Ewing sarcoma, Kaposi's sarcoma and gastrointestinal stromal tumors (GIST) will be excluded.
-
Subjects who received at least two prior systemic therapies (e.g., anthracyclines, taxanes, ifosfamide, gemcitabine, trabectedin, pazopanib, eribulin) for advanced or metastatic disease including at least one prior therapy based on anthracyclines as monotherapy or in combination. Neoadjuvant and adjuvant therapies can be considered as a prior line of treatment if the time to recurrence from completion of treatment was ≤ 12 months. Previous therapy with anthracyclines is not compulsory in situations of contraindications to this class of drugs. All previous therapies must have completed ≥ 3 weeks (21 days) prior to study treatment start.
-
Evidence of disease progression after prior line of therapy for advanced or metastatic disease.
-
Patients must have at least one unidimensionally measurable lesion by computed tomography as defined by RECIST criteria v.1.1. If only one lesion is present at screening this lesion should not have been irradiated during previous treatments.
-
Life expectancy of at least 3 months in the judgment of the investigator.
-
ECOG ≤ 2.
-
Documented negative test for HIV-HBV-HCV. For HBV serology: the determination of HBsAg 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.
-
Female patients: negative serum pregnancy test at screening for women of childbearing potential (WOCBP)*. WOCBP must agree to use, from the screening to six months following the last study administration of L19TNF and/or DTIC, highly effective contraception methods, as defined by the "Recommendations for contraception and pregnancy testing in clinical trials" issued by the Head of Medicine Agencies' Clinical Trial 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 from the screening to six months following the last administration of L19TNF and/or DTIC (e.g. condom with spermicidal gel). Double-barrier contraception is required.
-
Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
-
Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures.
- 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).
- Anti-cancer treatment with radiation therapy (with the exception of radiation of single lesions for palliative reasons, e.g. pain management which then are not taken as indicator lesions for iRECIST response), chemotherapy, targeted therapies, immunotherapy, hormones or other antitumor therapies within 3 weeks prior to study treatment start.
- Subjects who participated in an investigational drug or device study within 3 weeks prior to study treatment start.
- Previous treatment with TNF or L19TNF or DTIC.
- Known history of allergy to intravenously administered human proteins/peptides/antibodies and any other constituent of the product.
- Absolute neutrophil count (ANC) < 1.5 x 109/L, platelets < 100 x 109/L and hemoglobin (Hb) < 9.0 g/dl, with the exception of values lower than these due to cytologically or histologically proven marrow metastasis, which will not constitute exclusion criteria.
- Chronically impaired renal function as expressed by creatinine clearance < 60 mL/min or serum creatinine > 1.5 ULN.
- Inadequate liver function (ALT or AST ≥ 3 x ULN or ALP or GGT ≥ 2.5 x ULN, or total bilirubin ≥ 1.5 x ULN). For patients with metastatic lesions in the liver ALT, AST, GGT or ALP ≥ 5 x ULN.
- Any severe concomitant condition which in the opinion of investigators makes it undesirable for the patient to participate in the study or which could jeopardize compliance with the protocol.
- History within the last year of cerebrovascular disease and/or acute or subacute coronary syndromes including myocardial infarction, unstable or severe stable angina pectoris.
- Heart insufficiency (> Grade II, New York Heart Association (NYHA) criteria).
- Clinically significant cardiac arrhythmias.
- Abnormalities observed during baseline ECG and echocardiogram investigations that are considered as clinically significant by the investigator.
- Uncontrolled hypertension.
- Ischemic peripheral vascular disease (Grade IIb-IV according to Leriche-Fontaine classification).
- Severe diabetic retinopathy such as severe non-proliferative retinopathy and proliferative retinopathy.
- Major trauma including major surgery (such as abdominal/cardiac/thoracic surgery) within 4 weeks of administration of study treatment.
- Pregnancy or breast-feeding.
- Requirement of chronic administration of corticosteroids or other immunosuppressant drugs. Limited use of corticosteroids to treat or prevent acute hypersensitivity reactions is not considered an exclusion criterion.
- Presence of active and uncontrolled infections or other severe concurrent disease, which, in the opinion of the investigator, would place the patient at undue risk or interfere with the study.
- Known active or latent tuberculosis (TB).
- Concurrent malignancies other than soft-tissue sarcoma, unless the patient has been disease-free for at least 2 years.
- Serious, non-healing wound, ulcer or bone fracture.
- Allergy to study medication or excipients in study medication.

- Concurrent use of other anti-cancer treatments or agents other than study medication.
- Protected adults (i.e., persons referred to as adults who are under legal protection measure or unable to express their consent) or persons under the protection of justice.
