Somatostatin Receptor Positive study: [177Lu]Lu-DOTA-TATE vs Octreotide LAR
Official title Study to Evaluate the Efficacy and Safety of [177Lu]Lu-DOTA-TATE in Patients With Grade 1 and Grade 2 Advanced GEP-NET
ClinicalTrials.gov ID: NCT06784752
What this study is testing
What is Octreotide LAR?
It is an investigational long‑acting injectable medicine being studied as part of a treatment for somatostatin receptor‑positive advanced gastroenteropancreatic neuroendocrine tumors. It is designed to bind somatostatin receptors and reduce hormone secretion and tumor cell signaling.
Also referred to as Somatuline Depot, octreotide.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study aims to find out how well the combination of Lu‑177 DOTA‑TATE and long‑acting octreotide works and how safe it is compared with octreotide alone.
- Who it's for
- Adults who have just been diagnosed with somatostatin‑receptor‑positive, well‑differentiated Grade 1 or Grade 2 advanced gastroenteropancreatic neuroendocrine tumors.
- What's involved
- Participants will receive either the radioactive therapy Lu‑177 DOTA‑TATE together with octreotide injections, or octreotide injections alone, along with scheduled clinic visits and imaging tests.
- Phase 3: a large, late-stage study
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
