177Lu-PP-F11N in Combination With Sacubitril for Receptor Targeted Therapy and Imaging of Metastatic Thyroid Cancer

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years - 64 Years
Gender All

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
