London, OntarioAges 18 years+ - NCT04575844RecruitingPhase 4
Exercise and GLP-1 to improve insulin and muscle blood flow
This study looks at whether doing exercise and a GLP-1 medicine (liraglutide or similar) can improve how your body uses insulin and how blood flows to your muscles. It is aimed at adults with metabolic syndrome who do not already have diabetes.
Charlottesville, VirginiaAges 21–60 - NCT04577014RecruitingPhase 1/Phase 2
Retifanlimab plus chemotherapy for advanced soft tissue sarcoma
This trial tests retifanlimab (an immunotherapy that helps your immune system recognize cancer) combined with gemcitabine and docetaxel chemotherapy. It’s for people with advanced soft tissue sarcoma that can’t be safely removed with surgery, aiming to shrink tumors and improve outcomes.
New York, New YorkAges 18 years+ - NCT04608630RecruitingPhase 2
Preventing bone loss in ICU patients with anti-bone drugs
This Phase 2 study tests whether zoledronic acid or denosumab can prevent bone thinning in critically ill adults after staying in the ICU. It may help reduce the risk of future bone fractures if your body is at higher risk during and after critical illness.
Sydney, New South WalesAges 50 years+ - NCT04621201Recruiting
Testing tumor genetics in young people with bone sarcomas
This study looks at the genetic (DNA) features of tumors in children, teens, and young adults with osteosarcoma, Ewing sarcoma, or synovial sarcoma. It may help researchers better understand these cancers by analyzing a fresh tumor sample and a blood sample.
Torino, TurinAges Up to 24 years - NCT04621435RecruitingPhase 1
PET imaging test for solid tumors using FAP-2286
This Phase 1 study tests a special imaging scan (using FAP-2286) to see solid tumors in people who have already been diagnosed. It may help doctors better detect where cancer is in the body and how to plan treatment.
San Francisco, CaliforniaAges 18 years+ - NCT04625907RecruitingPhase 1/Phase 2
Study testing treatment options for children and adults with RMS
This study tests different treatment approaches for rhabdomyosarcoma (RMS) in children and adults, including newly diagnosed high-risk cases, people needing radiotherapy, and people whose RMS has returned. It’s designed to find safer dosing and more effective therapy while checking whether participants can proceed based on health and timing requirements.

Study drug plus docetaxel and abiraterone for advanced prostate cancer
This trial tests a new targeted cancer drug (PDS01ADC) combined with standard treatments docetaxel and abiraterone for men with advanced prostate cancer that has spread. The goal is to see if the combination is safe and whether it can control cancer better than current approaches.
Bethesda, MarylandAges 18–110 - NCT04638790RecruitingPhase 3
