• Sex: All
• Target Recruitment: 100

Inclusion Criteria

1. Written informed consent and any locally-required authorization (EU Data Privacy Directive in the EU) obtained from the subject prior to performing any protocol-related procedures, including screening evaluations
2. Age = 18 years at time of study entry
3. Body weight > 30kg at study inclusion
4. Histologically confirmed diagnosis of metastatic or advanced soft tissue sarcoma of intermediate or high grade [according to FNCLCC score; intermediate=grade 2 score of 4-5 points, high grade = grade 3 score of 6-8 points] with disease progression within 6 months prior to study inclusion:
• Fibrosarcoma
• Pleomorphic high grade sarcoma (malignant fibrous histiocytoma”)
• Leiomyosarcoma
• Liposarcoma (myxoid liposarcoma, dedifferentiated liposarcoma, pleomorphic liposarcoma)
• Malignant glomus tumor
• Rhabdomyosarcoma, alveolar or pleomorphic (excluding embryonal)
• Vascular sarcoma (angiosarcoma)
• Synovial sarcoma
• High-grade sarcoma, not otherwise specified (NOS)
• Malignant peripheral nerve sheath tumors
• Other types of sarcoma (not listed as ineligible), if approved by the coordinating investigator/study coordinator.
Excluding:
Uncertain differentiation (epithelioid, alveolar soft part, clear cell, desmoplastic small round cell, malignant mesenchymoma, PEComa), chondrosarcoma, Ewing sarcomas/PNET, chordoma, malignant solitary fibrous tumors, embryonal rhabdomyosarcoma, osteosarcoma, gastrointestinal stromal tumors, dermatofibrosarcoma protuberans, inflammatory myofibroblastic sarcoma (low-grade), neuroblastoma, malignant mesothelioma, and mixed mesodermal tumors of the uterus
(Study inclusion is based on local histopathological diagnosis).
5. Metastatic or locally advanced STS, not amendable to surgery with curative intention.
6. No prior treatment line for advanced or metastatic disease.
7. ECOG performance status 0-2
8. Patients with measurable disease (at least one uni-dimensionally measurable target lesion by CT-scan or MRI) according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1) are eligible.
9. If prior palliative radiotherapy has been given to metastatic lesions: either =1 measurable lesion remains outside the radition field or the sole lesion meets RECIST 1.1 criteria for progression at study entry.
10. Patients with bone lesions as the only measurable lesion are eligible, provided that lesions consist of soft tissue, which is measurable via CT or MRI.
11. Prior radiotherapy and surgery are allowed if completed 4 weeks (for minor surgery and palliative radiotherapy for bone pain: 2 weeks) prior to start of treatment and patient recovered from toxic effects.
12. Adequate blood count, liver-enzymes, and renal function:
• Haemoglobin = 9.0 g/dL
• Absolute neutrophil count (ANC) = 1.5 x 10^9/L (> 1500 per mm³)
• Platelet count = 100 x 10^9/L (>100,000 per mm³)
• Serum bilirubin = 1.5 x ULN. This will not apply to subjects with confirmed Gilbert’s syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only in consultation with their physician.
• AST (SGOT)/ALT (SGPT) = 2.5 x institutional upper limit of normal unless liver metastases are present, in which case it must be = 5x ULN
• Serum creatinine CL>40 mL/min by the Cockcroft-Gault formula or by 24-hour urine collection for determination of creatinine clearance
Males: Creatinine CL (mL/min) = Weight (kg) x (140 – Age)/ (72 x serum creatinine (mg/dL))
Females

Exclusion Criteria

1. Patients who are suitable for anthracycline-based combination therapies
2. Cardiac events such as arrhythmias, myocardial infarction, CHF, apoplexy, lung embolism within 6 months prior to study treatment
3. Mean QT interval corrected for heart rate (QTc) =470 ms calculated from 3 electrocardiograms (ECGs) using Fredericia’s correction
4. Uncontrolled severe hypertension (failure of diastolic blood pressure to fall below 100 mmHg and systolic blood pressure>160 mmHg)
5. Previous malignancy (other than STS) which either progresses or requires active treatment
Exceptions are: basal cell cancer of the skin, pre-invasive cancer of the cervix, T1a or T1b prostate carcinoma, or superficial bladder tumor [Ta, Tis and T1]
6. History or clinical evidence of CNS metastases
Exceptions are: Subjects who have completed local therapy and who meet both of the following criteria:
a) are asymptomatic and
b) have no requirement for steroids 6 weeks prior to start of study treament. Screening with CNS imaging (CT or MRI) is required only if clinically indicated or if the subject has a history of CNS metastases
7. Active or prior documented autoimmune disease within the past 2 years NOTE: Subjects with vitiligo, Grave’s disease, or psoriasis not requiring systemic treatment (within the past 2 years) are not excluded
8. Active or prior documented inflammatory bowel disease (e.g. Crohn’s disease, ulcerative colitis)
9. History of primary immunodeficiency
10. History of allogeneic organ transplant
11. History of hypersensitivity to durvalumab, tremelimumab (alone or in combination), doxorubicin or any of the constituents of the products
12. Medication that is known to interfere with any of the agents applied in the trial
13. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, active peptic ulcer disease or gastritis, active bleeding diatheses including any subject known to have evidence of acute or chronic hepatitis B, hepatitis C or human immunodeficiency virus, or psychiatric illness/social situations that would limit compliance with study requirements or compromise the ability of the subject to give written informed consent
14. Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of study medication Note: Local surgery of isolated lesions for palliative intent is acceptable
15. Any unresolved toxicity >CTCAE grade 2 from previous anti-cancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria
• Patients with Grade=2 neuropathy will be evaluated on a case-by-case basis after consultation with the Coordinating Investigator
• Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab or tremelimumab (if applicable) may be included only after consultation with the Coordinating Investigator
16. Any prior Grade=3 immune-related adverse event (irAE) while receiving any previous immunotherapy agent, or any unresolved irAE>Grade 1
