This is a randomized phase II non-comparative study. Patients with GEP-NET G1-G2 with progressive disease, somatostatin receptor (SSR) positive and FDG negative will be enrolled in the study and will be randomly assigned to 2 different dosages (total activity of 25.9 GBq and total activity of 18.5 GBq). The two levels of dosages are:~Total activity of 25.9 GBq 100 mCi for 7 cycles at 6 ± 2 weeks (700 mCi)~Total activity of 18.5 GBq 100 mCi for 5 cycles at 6 ± 2 weeks (500 mCi) The randomized study design allows for two active treatments to be evaluated in a comparable patient population. The estimates of primary objectives can be evaluated for each regimen separately by a Bryant and Day design. While the sample size is not powered for statistical test of a specific hypothesis for comparison between groups, this study design allows the unbiased collection of activity and safety in these two regimens in the same population, which will be useful for planning future studies.
