Exploration of Molecular Biomarkers for Lu-177 DOTATATE Therapy in Midgut Neuroendocrine Tumor (GENEBIOLuNET)
Midgut Neuroendocrine Tumors
About this trial
This is an interventional diagnostic trial for Midgut Neuroendocrine Tumors focused on measuring Lu-177 Dotatate, transcript analysis and variation, molecular biomarkers, midgut neuroendocrine tumors
Eligibility Criteria
Inclusion Criteria:
- Patients ≥18 years old; histopathologically confirmed grade 1-2 midgut neuroendocrine tumor with documented progression during the year preceding inclusion upon RECIST criteria on computerized tomography, Octreoscan or Ga-68 positron emission tomography/computerized tomography
- Patients having an indication for Lu-177 Dotatate treatment validated during multidisciplinary meeting coordinated by Pr Rosine Guimbaud under RENATEN coordination;
- Measurable target lesions upon RECIST criteria
- Patients on somatostatin analogues treatment. Every somatostatin analogue injection should be organized to be administered 24 to 48 hours after each injection of Lu-177 Dotatate.
- All patients should be in a clinical state allowing them to continue treatment.
- Social security affiliation is mandatory.
Exclusion Criteria:
- Patients on chemotherapy or other targeted therapy within the 4 months preceding peptide receptor radionuclide therapy
- Fertile patients refusing active contraception ; pregnancy.
- Patients with prior chemotherapy or peptide receptor radionuclide therapy administration
- Patients with uncontrollable psychotic disorders
- Renal hepatic and medullary insufficiency
Sites / Locations
- CHU de Toulouse
Arms of the Study
Arm 1
Experimental
Non-drug intervention type
Exploration of gene transcript variation on seriate blood samples before treatment, before and after the 2nd and the 4th Lu-Dotatate injection and before and after the 6 month post treatment follow-up. Measures of stability and reproducibility of selected gene transcripts and miRNA as radio sensitivity genes or progressive metastatic midgut neuroendocrine tumors genetic signatures before and during Lu-177 Dotatate internal vectorized therapy, as well as on the 6-month follow-up.
