Clinical Trials

The purpose of this study is to assess the side effects and best dose of a genetically engineered measles virus for treating patients who have a cancerous peripheral nerve sheath tumor that cannot be removed by surgery (unresectable) or that has come back after a period of improvement (recurrent).

Information regarding the delay in diagnosis as well as the causes of the delay are lacking in the U.S. Specifically, we aim to identify patient factors and provider factors that contribute to delayed diagnosis of sarcoma.

The purpose of this study is to see how well lorvotuzumab mertansine works in treating younger patients with Wilms tumor, rhabdomyosarcoma, neuroblastoma, pleuropulmonary blastoma, malignant peripheral nerve sheath tumor (MPNST), or synovial sarcoma that has returned or that does not respond to treatment. Antibody-drug conjugates, such as lorvotuzumab mertansine, are created by attaching an antibody (protein used by the body's immune system to fight foreign or diseased cells) to an anti-cancer drug. The antibody is used to recognize tumor cells so the anti-cancer drug can kill them.

The goal of this study is to create a comprehensive system of tissue banking of samples from Mayo Clinic Arizona patients with a clinical diagnosis of sarcoma who will or have undergone a surgical procedure to remove the sarcoma.  The tissue samples will be used for future research of sarcoma at Mayo Clinic and future research at Mayo Clinic to learn about, prevent, or treat other health problems.
