Patient unable to follow and comply with the study procedures because of any geographical, familial, social or psychological reasons, 8. Patient unable to swallow, 9. Known hypersensitivity to any involved study drug or of its formulation components, 10. Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg. Thyroxine, insulin or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc…) is not considered a form of systemic treatment and is allowed. 11. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment, 12. History of idiopathic pulmonary fibrosis, history of non-infectious pneumonitis that required steroids, current pneumonitis/interstitial lung disease, drug-induced pneumonitis, organizing pneumonia, or evidence of active pneumonitis on screening chest CT scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted, 13. Has a known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection. 14. Has a known history of Human Immunodeficiency Virus (HIV) infection (HIV1/2 antibodies) and/or of active TB (Bacillus Tuberculosis), 15. Treatment with anticoagulants such as anti-Vitamin K, thrombin or Factor Xa inhibitors, or antiplatelet agents (e.g., clopidogrel), 16. Previous allogenic bone marrow transplant or solid organ transplantation, 17. Has an active infection requiring systemic treatment at study entry, 18. The subject has a corrected QT interval calculated by the Fridericia formula (QTcF) > 500 ms within 28 days before treatment. Note: if initial QTcF is found to be > 500 ms, two additional ECGs separated by at least 3 minutes should be performed. If the average of these three consecutive results for QTcF is = 500 ms, the subject meets eligibility in this regard, 19. The subject requires chronic concomitant treatment of strong CYP3A4 inducers (e.g., phenytoin, carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John’s Wort). Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated list such as http://medicine.iupui.edu/clinpharm/ddis/table.aspx; medical reference texts such as the Physicians’ De

| Main Objective: Assessment of the efficacy of Pembrolizumab and Cabozantinib in terms of 6-month non-progression (as per RECIST v1.1 criteria) independently for 3 stratas: • Advanced undifferentiated pleomorphic soft-tissue sarcoma • Advanced osteosarcoma • Advanced Ewing sarcoma ;Secondary Objective: Each strata will be analysed independently. • Assessment of the efficacy of the treatment strategy in terms of best overall response (as per RECIST v1.1 criteria), 1-year Progression-free survival (PFS, as per RECIST v1.1 criteria), and 1-year overall survival (OS). • Assessment of the safety profile of the treatment strategy using the Common Terminology Criteria for Adverse Events (CTCAE) from the NCI v5.0. • Assessment of the Growth modulation index (GMI), defined for each patient as the ratio of the PFS on the current treatment strategy to the PFS on the previous line of therapy (Von Hoff 1998), in patients with documented progression under a previous line at inclusion. • Assessment of the efficacy of the treatment strategy in terms of 6-month non-progression according to iRECIST (Seymour 2017; central radiological review data) • Translational research on blood and tumor samples obtained at baseline and several time points during treatment.;Primary end point(s): • The primary efficacy endpoint for advanced undifferentiated pleomorphic sarcoma (stratum 1), advanced osteosarcoma (stratum 2) and advanced Ewing sarcoma (stratum 3) is 6-month non-progression (as per RECIST evaluation criteria v1.1). • Non-progression: complete response, partial response or stable disease more than 24 weeks as per RECIST evaluation criteria v1.1. • Objective response: complete response or partial response as per RECIST evaluation criteria v1.1. • Following RECIST v1.1 recommendations: o claimed responses (complete or partial response) will have to be confirmed at least 4 weeks later; o 6-month radiological data will be reviewed by an independent expert radiologist. o Primary efficacy | — |

| Secondary end point(s): • Best overall response defined as per RECIST v1.1 criteria. • 1-year progression-free survival (PFS): PFS is defined as the time from study treatment initiation to the first occurrence of disease progression or death (of any cause), whichever occurs first. • 1-year overall survival (OS): OS is defined as the time from study treatment initiation to death (of any cause). • Growth modulation index (GMI), defined for each patient as the ratio of the PFS on the current treatment strategy to the PFS on the previous line of therapy (Von Hoff, 1998), in patients with documented progression at inclusion. • Toxicity will be graded using the Common Terminology Criteria for Adverse Events (CTCAE) from the NCI v5.0. • Immune-related response is defined according to iRECIST (Seymour 2017). Analysis will be based on data centrally reviewed by an expert radiologist. • Performance of pharmacodynamic (PD)/mechanism of action (MOA) biomarkers analysis as well as predictive biomarkers analysis (levels of angiogenic and immunologic biomarkers) in blood and tumor tissue at baseline and different study time points. o Blood samples will be mandatory collected at predefined timepoints for assessment of: o Serum/plasma cytokines levels (TNF?, TNFa, TGFß, IL2, 4, 6, 10), VEGF, HGF, sMET, sVEGFR2 (ELISA) o Treg, CD4+ CD8+ and DR lymphocytes subpopulations monitoring, CD8+/Treg ratio (flow cytometry) o Plasma levels of Kynurenine and Kynurenine to Tryptophan ratio (ELISA and LC/MS) o Availability of a < 3 months, non subsequently treated or fresh tumor samples, with frozen material available will be mandatory at inclusion for baseline, and a second sampling will be mandatorily collected during treatment at C2Day8 (+/- 3 days). Formalin-fixed, paraffin-embedded biopsy samples will be analysed for (but not limited to) CD8+ effectors, CD68 and 163 Macrophages and FOXP3+ cells infiltrates as well as PDL1, IDO1, CD31 (microvessel density), as well as MET and ph | — |
