Ensure the safety and tolerability, Determine Quality of Life (QoL) • Exploratory: Characterize the TME Participants will be asked to ensure * Baseline biopsy and further optional biopsies * Treatment propranolol 40 mg BID and pembrolizumab 2 mg/kg Q3 weeks * Evaluation, blood counts, QoL and blood samples for biomarkers according to schedule
Detailed description
Soft tissue sarcomas (STS) are mesenchymal derived tumors consisting of more than 50 subtypes, showing high metastatic features in approximately 50% of patients with intermediate and high-grade tumors. In spite of optimizing sequence of conventional systemic treatments with chemotherapy and tyrosine kinase inhibitors with an increase in overall survival from 12 to 18 months, the prognosis has not changed and is still a dismal 8% overall survival at 5 years. After four decades doxorubicin is still first line treatment as no new drugs has proven more effective and/or less toxic. Thus, new treatment modalities are needed. Angiosarcomas (AS) and Undifferentiated Pleomorphic Sarcoma (UPS), comprising approximately 2% and 10% of STS respectively, are by definition high grade sarcomas characterized by an aggressive course. In the non-resectable advanced and metastatic setting treatment options are limited with short term palliative intent with median overall survival (OS) \< 12 months. Patients are often elderly and with co-morbidities, increasing risk of severe toxicity from chemotherapy leading to significant deterioration of Quality of Life. New therapeutic options are needed. Emerging results on immune modulating therapy with immune checkpoint inhibitors (ICI), have shown promising signals of potential benefit in certain subtypes of STS, especially in UPS and AS. In tumors, neovascularization facilitate hypoxia, glucose deprivation and increased VEGF production leading to an immune suppressive tumor microenvironment (TME). This can in part be reverted by anti-angiogenic therapy including multitarget tyrosine kinase inhibitors. A proposed novel approach for targeting angiogenesis and potential immune modulatory mechanisms is through beta-adrenergic receptor (βAR) signaling. Preclinical data support combining βAR blockade with propranolol in combination with anti PD-1, and recently a phase 1 study showed the combination propranolol and pembrolizumab was well tolerated in melanoma patients. This study is an open label, Simon two-stage single arm phase 2 study of pembrolizumab and propranolol in two separate cohorts. Patients will receive pembrolizumab 2 mg/kg every 3 weeks and propranolol 40 mg x2 daily until progression, unacceptable toxicity or patient withdrawal for a maximum of two years. Up to 40 patients will be included in each separate cohort. Up to 18 patients in stage 1 and up to 22 patients in stage 2. The primary objective is to determine progression-free survival rate (PFSR) at 3 months by Response Evaluation Criteria in Solid Tumors (RECIST v1.1) The secondary objectives are to determine objective response rate (ORR) and duration of Response (DOR) using RECIST v 1.1, PFS and OS. Ensure safety and tolerability according to Common Terminology Criteria for Adverse Events (CTCAE version 5.0), and determine Quality of Life (QoL) using the 30 item European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ C30) questionnaire The explorative objective is to characterize the TME, immune cells and markers both in tumors and in peripheral blood.

Inclusion criteria
* Subjects must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal subject care * Subjects must be willing and able to comply with scheduled visits, treatment schedule, laboratory testing, and other requirements of the study * Histologically confirmed diagnosis of unresectable locally advanced or metastatic Angiosarcoma or Undifferentiated Pleomorphic Sarcoma, who has progressed/failed to provide clinical benefit on first line standard chemotherapy. * Age ≥18 years * Eastern Cooperative Oncology Group Performance Status (ECOG PS) score of ≤2 at the time of enrollment. * Evaluable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST version 1.1). * Available material from archived formalin-fixed paraffin-embedded tumor tissue obtained within 3 months of study enrollment for biomarker related studies. If not sufficient or available, a newly obtained core or excisional biopsy of a tumor lesion may be performed. * Patients must have normal organ and marrow function as defined below: * Absolute neutrophil count (ANC) ≥ 1 x 10⁹/L * Platelet count ≥ 75 x 10⁹/L * Serum bilirubin ≤ 1.5 x upper limit of normal (ULN) (patients with Gilbert's Syndrome must have a total bilirubin ≤ 50 mmol/L) * Aspartate transaminase (AST)/Alanine transaminase (ALT) ≤ 5 x ULN * Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min (using the Cockcroft-Gault formula) * Women of childbearing potential (WOCBP): Agreement to use contraceptive methods with a failure rate of \< 1 % per year during the treatment period and for at least 120 days after the treatment. Safe contraceptive methods for women are birth control pills, intrauterine device, contraceptive injection, contraceptive implant,contraceptive patch or contraceptive vaginal ring. * Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year during the treatment period and for at least 120 days after the treatment. * Women who are not of childbearing potential (ie, who are postmenopausal or surgically sterile) as well as azoospermic men do not require contraception
