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 109/L (> 1500 per mm3)
• Platelet count ≥ 100 x 109/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 (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance 13. Adequate cardiac function (left ventricular ejection fraction ≥50% as assessed by ECHO) 14. Female subjects must either be of non-reproductive potential (ie, post-menopausal by history: ≥60 years old and no menses for ≥1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry.

15. Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.

• 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 17. Known history of previous clinical diagnosis of tuberculosis 18. Receipt of live attenuated vaccination within 30 days prior to study entry or within 30 days of receiving durvalumab 19. Female subjects who are pregnant, breast-feeding or male or female patients of reproductive potential who are not employing an effective method of birth control (failure rate of less than 1% per year) 20.

Participation in another clinical study with an investigational product during the last 30 days before inclusion 22. Any previous treatment with a PD-1 or PD-L1 or CTLA-4 inhibitor, including durvalumab and tremelimunab 23. Current or prior use of immunosuppressive medication within 28 days before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid 24. Receipt of the last dose of anti-cancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) ≤ 21 days prior to the first dose of study drug or ≤4 half-lifes of the agent administered, which ever comes first.

25. Previous enrollment or randomization in the present study (does not include screening failure).

26. Patient who has been incarcerated or involuntarily institutionalized by court order or by the authorities (§ 40 Abs. 1 S. 3 Nr. 4 AMG).

27. Patients who are unable to consent because they do not understand the nature, significance and implications of the clinical trial and therefore cannot form a rational intention in the light of the facts [§ 40 Abs. 1 S. 3 Nr. 3a AMG].

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:

1. are asymptomatic and

2. 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 (HIV), 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.
