Individualized Peptide Vaccine is a special type of treatment designed specifically for each patient. It is made up of small proteins called peptides that are unique to the cancer cells in a patient’s body. The goal of this vaccine is to help the immune system recognize and attack the cancer cells more effectively. In this trial, the vaccine is used for patients with a type of cancer called fusion-driven sarcomas, which have spread to other parts of the body. The vaccine is given after the standard treatment to see if it can boost the body’s immune response against the cancer.

Ewing Sarcoma – Ewing sarcoma is a type of cancer that occurs in bones or in the soft tissue around the bones. It often begins in the long bones of the arms and legs, pelvis, or chest. The disease is characterized by the rapid growth of cancer cells, which can lead to pain and swelling in the affected area. As it progresses, the tumor may spread to other parts of the body, including the lungs and other bones. The exact cause of Ewing sarcoma is not well understood, but it is believed to involve genetic changes. It primarily affects children and young adults.

Alveolar Rhabdomyosarcoma – Alveolar rhabdomyosarcoma is a rare and aggressive form of cancer that arises from skeletal muscle tissue. It is most commonly found in the arms, legs, and trunk, but can also occur in other areas of the body. The disease is characterized by the formation of small, round cancer cells that grow rapidly and can invade surrounding tissues. As it progresses, it may spread to other parts of the body, such as the lungs, lymph nodes, and bone marrow. This type of cancer is more common in adolescents and young adults. The exact cause is not fully understood, but genetic factors are believed to play a role.

Synovial Sarcoma – Synovial sarcoma is a rare type of cancer that typically occurs near the joints of the arm, neck, or leg. It is characterized by the growth of cancerous cells in the soft tissues, which can include muscles, fat, blood vessels, or nerves. The disease often presents as a slow-growing mass, which may cause pain or swelling as it enlarges. Over time, the tumor can invade nearby tissues and spread to other parts of the body, such as the lungs. Synovial sarcoma is most commonly diagnosed in young adults. The exact cause is not well understood, but it is associated with a specific genetic mutation.
