Conditions

Summary

The purpose of the current study is to evaluate the efficacy and safety of \[177Lu\]Lu-DOTA-TATE plus octreotide long-acting release (LAR) versus octreotide LAR alone in newly diagnosed patients with somatostatin receptor positive (SSTR+), well differentiated Grade1 and Grade 2 (G1 and G2) (Ki-67 \<10%) advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs) with high disease burden

Plain Language Summary

Simplified for easier understanding

This study is testing a radioactive treatment called lutetium DOTATATE (also known as Lutathera) for people with slow-growing gut or pancreatic neuroendocrine tumors (NETs) — cancers that start in hormone-producing cells — that are at an early but significant stage of disease. **You may be eligible if...** - You have a Grade 1 or Grade 2 neuroendocrine tumor in the gut or pancreas (GEP-NET) - Your tumor has spread or cannot be removed with surgery - Your tumor was diagnosed within the past 6 months - Your tumor burden is considered high (e.g., a large tumor or multiple metastases) - Your tumor absorbs a special tracer on a DOTATATE scan **You may NOT be eligible if...** - Your tumor is Grade 3 or a more aggressive type - Your tumor does not show up on a DOTATATE scan - You have significant kidney or bone marrow problems Talk to your doctor to see if this trial is right for you.
