The MetNET-2 Trial

Summary

This is a Pilot, One-arm, Open-label, Prospective Study to evaluate Safety of Lanreotide 120 mg ATG in combination with Metformin in patients with advanced progressive GI or lung carcinoids. The patient population will include patients with a histologically documented diagnosis of Well differentiated NET, G1-G2 according to the last WHO Classification criteria for GI and lung NET carcinoids.
