RESTON, Va - German researchers have developed a novel diagnostic and therapeutic (theranostic) procedure for patients with ductal pancreatic adenocarcinoma, a deadly cancer with an extremely poor prognosis (five-year survival rate of less than 5 percent) and limited treatment options. The study is featured in the May issue of The Journal of Nuclear Medicine.

In early preclinical studies with animal models, the novel procedure significantly inhibited tumor growth. Focusing on the neurotensin receptor 1 (NTR1), a protein that is overexpressed in ductal pancreatic adenocarcinoma, researchers developed a DOTA-conjugated NTR1 antagonist 3BP-227 labeled with the radioisotope lutetium-177 (177Lu) to treat and monitor therapy.

For this study, 6 patients with confirmed metastatic ductal pancreatic adenocarcinoma, who had exhausted all other treatment options, received 177Lu-3BP-227 as salvage therapy. Scintigraphy and single-photon emission computed tomography was used with computed tomography (SPECT/CT) to determine the tumor uptake and the patients' eligibility for treatment. If the patient's condition allowed, 18F-FDG positron emission tomography (PET)/CT imaging was performed 8-12 weeks after therapy to determine treatment efficacy.

177Lu-3BP-227 was well tolerated by all patients, with the most severe adverse reaction a reversible grade 2 anemia. One patient experienced significant improvement of symptoms and quality of life--surviving 13 months from diagnosis and 11 months from the start of 177Lu-3BP-227 therapy.

This study provides the first clinical evidence of the feasibility of treating ductal pancreatic adenocarcinoma using 177Lu-3BP-227.

"The research presented warrants further development of 177Lu-3BP-227, in order to provide patients with more effective treatment and less side effects than cytotoxic chemotherapy," explains Christiane Smerling, PhD, head of Nuclear Medicine and Imaging at 3B Pharmaceuticals GmbH in Berlin, Germany.

She points out, "Exploiting a hitherto underexplored receptor, these findings broaden the scope of nuclear medicine treatment for pancreatic adenocarcinoma and potentially other indications expressing neurotensin receptors, such as Ewing sarcoma. A theranostic approach using molecular imaging to identify potential responders will allow more effective treatment of a highly underserved patient population."

The Society of Nuclear Medicine and Molecular Imaging (SNMMI) is an international scientific and medical organization dedicated to advancing nuclear medicine and molecular imaging, vital elements of precision medicine that allow diagnosis and treatment to be tailored to individual patients in order to achieve the best possible outcomes.

SNMMI's more than 15,000 members set the standard for molecular imaging and nuclear medicine practice by creating guidelines, sharing information through journals and meetings and leading advocacy on key issues that affect molecular imaging and therapy research and practice.
