Treatment Using 177Lu-DOTA-EB-TATE in Patients With Advanced Neuroendocrine Tumors

• Status: Unknown status
• Trial end date: 2019-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This is an open-label, non-controlled, non-randomized study to investigate the long-lasting radiolabeled somatostatin analogue based peptide receptor radionuclide therapy and evaluate response to 177Lu-DOTAEB-TATE in patients with advanced metastatic neuroendocrine tumors. Different groups with doses of 0.37GBq-0.74GBq (10-20 mCi) and 1.85GBq (50 mCi)of 177Lu-DOTA-EB-TATE,3.7GBq (100 mCi)of 177Lu-DOTA-TATE will be injected intravenously. All patients will undergo 68Ga-DOTATATE PET/CT scans before and after the treatment.

Criteria

Inclusion Criteria:

• Adults who had neuroendocrine tumors and had metastasized, that were with histologically confirmed, inoperable and had showed disease progression according to Response Evaluation Criteria in Solid Tumors [RECIST]. Tumors were with well-differentiated histologic features and a Ki67 index of 0 to 20%. Target tumors were selected from CT, MRI, and 68Ga-DOTA-TATE PET/CT, with confirmed somatostatin receptorexpressing and at least one lesion has higher uptake than that of normal liver parenchyma on 68Ga-DOTA-TATE PET imaging within 1 weeks.

Exclusion Criteria:

• The exclusion criteria were a serum creatinine level of more than 150 μmol per liter, baseline measured GFR of less than 50 mL/min/1.73 m2, determined by 99mTc-DTPA renal function examination, a hemoglobin level of less than 8.0 g/dl, a white-cell count of less than 2.0× 109/L, a platelet count of less than 75 × 109/L, a total bilirubin level of more than 3 times the upper limit of the normal range and a serum albumin level of more than 3.0 g per deciliter, cardiac insufficiency including carcinoid heart valve disease, a severe allergy or hypersensitivity to radiographic contrast material, claustrophobia, and pregnancy or breastfeeding.
