FDA Approves Novel Radio-peptide Targeted Therapy Clinical Trial for Neuroendocrine Cancer: PRRT (Peptide Receptor Radionuclide Therapy)

For the first time in North America, neuroendocrine cancer patients have the opportunity to participate in a clinical trial of Lutetieum-177 (LU-177) with Octreotate.   Ebrahim S. Delpassand, MD, chief executive officer and medical director of Excel Diagnostics, announced that after several years of careful review the Food and Drug Administration (FDA) has approved the investigational new drug clinical trial.  Excel Diagnostics and Nuclear Oncology Center in Houston, Texas is the first research facility in the United States to receive authorization to initiate this much needed therapy.
Lutetieum-177 radionuclide is one of the radioactive materials used in PRRT, peptide receptor radionuclide therapy, as is Y-90 (Yttrium-90). When labeled with somatostatin analogs such as Octreotate, these agents can be used for progressive neuroendocrine tumors that are resistant to octreotide/interferon treatment or chemotherapy.  LU-177 Octreotate has been used in Europe for over a decade and is also available in Australia and India. It has a shorter path length in the tissue than Y-90 has and is less toxic to both the kidneys and bone marrow. During the past 15 years, studies of radio-peptide therapy for various neuroendocrine cancers have shown good clinical and radiological results with minimal side effects.

LU-177 Octreotate is administered along with intravenous amino acids, to protect the kidneys from radiation.  The Octreotate binds to somatostatin receptors on cells, thus providing highly targeted radiation to the tumors.  A patient has 4 sessions of the treatment, spaced six to ten weeks apart. The use of LU-177 Octreotate as a targeted treatment was pioneered by Dr. Eric Krenning and Dr. Dik J. Kwekkeboom at Erasmus Medical Center in Rotterdam, the Netherlands.

This therapy can be used for neuroendocrine tumors including carcinoid, islet cell carcinoma of the pancreas, oat cell carcinoma of the lung, pheochromocytoma, gastro-entero-pancreatic neuroendocrine tumors (GEPNETS), and rare thyroid cancers unresponsive to radioiodine.

The principal investigator for the U.S. program is Dr. Ebrahim S. Delpassand and the project is in collaboration with Baylor College of Medicine, St. Luke’s Episcopal Hospital and Radio-Isotope Therapy of America (RITA) Foundation in Houston.
