Neuroendocrine Tumor Liver Metastases Neuroendocrine Gastroenteropancreatic Tumour | Procedure: Positron emission tomography computed tomography (PET/CT) with Intra-hepatic (IAH) injection Procedure: Positron emission tomography computed tomography (PET/CT) with Intravenous (IV) injection Drug: LUTATHERA® by intra-arterial hepatic (IAH) injection Procedure: Scan | Phase 2 |
Liver metastases of neuroendocrine tumors of gastro-entero-pancreatic origin are one of the most limiting factors of patient survival. Peptide receptor radionuclide therapy with radiolabeled somatostatin analogs (SSA) such as LUTATHERA® represents now a major therapeutic option. As far as these metastases are mainly perfused by the hepatic artery, it could be relevant to deliver the treatment by intra-hepatic route, in order to achieve a maximized dose to the tumour when compared with a systemic conventional administration, while also reducing kidney and bone marrow toxicity. By using radiolabeled SSA for imaging and therapy, the present project aims to compare the uptake of 68Ga-DOTA-peptides after intra-hepatic versus intravenous injections for targeted liver metastases, as well as for dose limiting organs (kidney, spleen, healthy liver, bone marrow) and extra-hepatic lesions if present. We will also evaluate whether the intra-hepatic infusion of one treatment dose of LUTATHERA® after conventional treatment by 4 intravenous administrations, is safe.
Following 4 intravenous administrations of LUTATHERA® in GEP-NET with dominant liver metastases, patients who gave informed consent will be enrolled for 2 PET-scans, the first one after intra-hepatic injection of 68Ga-DOTA-peptides and the second one after intravenous injection for purpose of uptake comparison by 5 liver metastases chosen by radiologists on MRI.
In 10 patients who meet a predefined enhancement ratio of 3, a 5th dose of LUTATHERA® will be administered by intra-arterial hepatic injection. (Based on literature data, an average enhancement ratio of 3.75 is expected from intra-arterial injection compared to intravenous results; Kratochwil 2010). Those 10 patients will be evaluated for 177Lu-DOTA-peptide activity and residence time by SPECT/CT imaging.
Follow-up through 18 months will include clinical examination, MRI and CT scan, as usually performed in these clinical settings and progression
