Despite advances in multimodal therapy, outcomes remain poor with frequent disease recurrence and very limited options for patients with advanced disease.\n\nSelected somatostatin receptor (SSTR) family members, i.e., SSTR2, SSTR3 and SSTR5, are frequently overexpressed in DSRCT and SySa, providing the rationale for treatment with somatostatin analogues (SSA).\n\nPasireotide is a SSA with high affinity for SSTR1, -2, -3, and -5 and is approved for the treatment of Cushing's disease and acromegaly and has also shown activity in other cancers. In patients with advanced stage DSRCT and SySa, conventional chemotherapeutic approaches frequently lead to disease response, however, the duration of progression-free time after chemotherapy is short. The targeted approach with pasireotide after initial intensive multimodal treatment may have the potential to significantly improve outcome.", 'detailedDescription': 'Desmoplastic small round cell tumor (DSRCT) is an extremely rare, aggressive sarcoma. It originates from the serosal surface of the abdominal cavity and the hallmark characteristic of DSRCT is the EWSR1-WT1 gene fusion. Synovial sarcoma (SySa) is also a rare fusion-gene driven (SS18-SSX1, SS18-SSX2, or rarely, SS18-SSX4) soft-tissue sarcoma.\n\nSelected somatostatin receptor (SSTR) family members, i.e., SSTR2, SSTR3 and SSTR5, were highly expressed in patients with available transcriptome data, providing the basis for treatment with a somatostatin analog such as pasireotide with high affinity for SSTR1, 2, 3, and 5.\n\nThe primary aim of the study is to assess the clinical efficacy of pasireotide maintenance therapy for prolonging progression-free (PFS) and overall survival (OS) in patients with SSTR2/3/5-expressing advanced SySa and DSRCT. Furthermore measurable residual disease (MRD) before, during, and after pasireotide maintenance therapy are assessed. Pasireotide is applied in adults with 60 mg and in adolescents 60 mg (body surface area \\[BSA\\] \\>1.6 m²) or 40 mg (BSA 1.1-1.6 m²) via intragluteal via intragluteal depot injection every 28±3 days. The sample size is planned for the entire study population with subsequent sensitivity analysis in two subgroups, i.e., adolescents and adults. The primary efficacy analysis is be based on a two-sided, one-sample log-rank test using a significance level of 5%. The sample size was calculated assuming exponential data, planning for a power of 90% to detect a hazard ratio of 0.5. With a sample size of n=28, the expected number of events during the study is 22. Safety is assessed continuously according to CTCAE v5.0. The recruitment period is planned for 2 years starting in 2024 followed by a minimal follow-up of the last patient of 6 months leading to estimated trial completion in 2027.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '50 Years', 'minimumAge': '13 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nPatients meeting all of the following criteria are considered for enrolment into the trial:\n\n1.
