Trial Identification

Brief Title: Exploration of Molecular Biomarkers for Lu-177 DOTATATE Therapy in Midgut Neuroendocrine Tumor

Official Title: Pilot Study for Measuring Molecular Biomarkers and Their Capacity to Characterize Radionuclide Therapy With Lu-177 DOTATATE) in Metastatic G1-G2 Neuroendocrine Midgut Tumors

Study ID: NCT03667092

Study Description

Brief Summary: Midgut neuroendocrine tumours present an increasing incidence and poor survival at 5 years with limited therapeutic options for metastatic, non-operable cases. Lu-177 Dotatate, targeting somatostatin receptors, is an internal vectorized radiotherapy using Lu-177, an ideal radionuclide for peptide radionuclide therapy. In NETTER-1 phase III randomized clinical trial, Lu-177 Dotatate proved its superiority in increasing progression free survival for midgut neuroendocrine tumors. This study hypothesize that finding biomarkers of individual radio sensitivity for this type of internal vectorized therapy would allow treatment personalization. The protocol aim at studying transcript variations induced by this therapy.

Detailed Description: Internal vectorized therapy using Lu-177 Dotatate (abbreviated peptide receptor radionuclide therapy) was recently shown to improve progression free survival and response in metastatic progressive midgut neuroendocrine tumors (NETTER-1 phase III trial). Lu-177 Dotatate is administered as a series of four consecutive intra veinous injections of an activity of 7.4 gigabequerel every 8 weeks. In order to identify potential biomarkers of radio sensitivity to Lu-177 Dotatate, investigators aim to study the stability of gene/miRNA transcripts in the absence of Lu-177 Dotatate or at 6 months after treatment as well as the variations in transcript analysis after 2 Lu-177 Dotatate injections and at the end of the treatment. Transcript variation analysis will be confronted and correlated with peripheral blood pharmacokinetic studies aimed at calculating time activity curves and provide biodosimetry information; other correlations with imaging modalities assessment of dosimetry or disease response to treatment or toxicity effects induced by Lu-177 Dotatate will also be studied.
