T-Cell Immunotherapy Research Expands to More Solid Tumors

Diagnosed in 2014 with Wilms tumor, Mason had his right kidney removed and received 14 rounds of chemotherapy to beat his cancer. The care Mason received was lifesaving, but kids deserve better treatment options. STRIvE-01, a new CAR T-cell immunotherapy trial at Seattle Children’s will target relapsed or refractory sarcoma, kidney and neuroblastoma tumors, giving new hope to patients everywhere.

Immunotherapy is the next great advancement in cancer treatment. Through cellular engineering, we enable the body’s own immune system to heal itself—without the harsh and often lifelong side effects of chemotherapy and radiation.

How Immunotherapy Works

The Results

Most patients see success within weeks.

Not only do most immunotherapy patients see their cancer quickly go into remission, the side effects of the treatment are less harmful than aggressive chemo or radiation. Finally, a more effective and gentle treatment for childhood cancer is within our reach. And we’re already seeing results: a recent Seattle Children’s pediatric leukemia clinical trial resulted in a 93% complete remission rate in children with relapsed leukemia.
