The purpose of this study is to determine the use of 177Lu-PP-F11N for imaging and therapy of patients with advanced medullary thyroid carcinoma (MTC). 177Lu-PP-F11N is a gastrin analogon, binding to cholecystokinin-2 receptors. This receptors show an overexpression on more than 90 % of medullary thyroid carcinomas.


A phase 0 study (Lumed study part A) was already performed, showing low toxicity of 177Lu-PP-F11N and tumor uptake in all patients. Co-injection of Physiogel (Gelofusin) showed insignificant reduction of kidney uptake and can therefore be omitted for a radionuclide therapy with 177Lu-PP-F11N. In this study, the effect of the NEP-1 inhibitor Sacuitril on the in-vivo stability of 177Lu-PP-F11N and the uptake, respectively radiation doses in MTC metastases and organs will be evaluated, using a cross-over design already used for the Lumed part A study. Each patient will receive two injections of 177Lu-PP-F11N, with and without additional medication with Sacuitril Imaging findings, acquired by SPECT/CT, will be compared to imaging with 68Ga-DOTATOC positron emission tomography (PET)/CT. The inclusion of 8 patients is planned.
