Phase I/II Study of Lutathera in Patients With Recurrent and/or Progressive High-Grade Central Nervous System Tumors and Meningiomas That Demonstrate Uptake on DOTATATE PET
Nationwide Children's Hospital
Summary
This study will evaluate the safety and efficacy of Lutathera (177Lu-DOTATATE) in patients with progressive or recurrent High-Grade Central Nervous System (CNS) tumors and meningiomas that demonstrate uptake on DOTATATE PET. The drug will be given intravenously once every 8 weeks for a total of up to 4 doses over 8 months in patients aged 4 to \<12 years (Phase I) or 12 to \</=39 years (Phase II) to test its safety and efficacy, respectively.

Description
Somatostatin receptors regulate cell growth through downstream modulation of both proliferation and apoptosis signaling pathways, and thus represent a potential therapeutic target. Lutathera (Lutetium \[Lu\]177 Dotatate) is a radionuclide therapy which binds type-2A somatostatin receptors (SST2A) and has recently gained FDA approval for the treatment of adult gastroenteropancreatic neuroendocrine tumors expressing SST2A. High SST2A expression has been consistently observed in medulloblastoma and other embryonal tumors (75-100% of cases) as well as in some HGGs and anaplastic ependymomas (13-8…
