A randomized, multi-center, open-label, active-controlled Phase 3 trial to assess the efficacy and safety of octreotide subcutaneous depot (CAM2029) versus octreotide LAR or lanreotide ATG in patients with gastroenteropancreatic neuroendocrine tumors
Gastroenteropancreatic neuroendocrine tumors
- Histologically confirmed, advanced (unresectable and/or metastatic), and well-differentiated NET of GEP or presumed GEP origin
- At least 1 measurable, somatostatin receptor-positive lesion according to RECIST 1.1 determined by multiphasic CT or MRI (performed within 28 days before randomization)
- Results from FDG-PET CT for patients with well-differentiated Grade 3 NET (if performed) must show that FDG avid areas of disease also are avid on somatostatin-receptor imaging
- Documented evidence of disease progression while on treatment (including SSAs) for locally advanced unresectable or metastatic disease
- Known central nervous system metastases
- Consecutive treatment with long-acting SSAs for more than 6 months before randomization
- Carcinoid symptoms that are refractory to treatment (according to the Investigator's judgement) with conventional doses of octreotide LAR or lanreotide ATG and/or to treatment with daily doses of ≤600 µg of octreotide IR
- Previous treatment with more than 1 cycle of targeted therapies such as mTOR inhibitors or vascular endothelial growth factor inhibitors, or more than 1 cycle of chemotherapy or interferon for GEP-NET
- Treatment of GEP-NET with trans-arterial chemoembolization or trans-arterial embolization within 12 months before screening
- Previously received radioligand therapy (PRRT) at any time
The purpose of this study is to compare the effectiveness and safety of CAM2029 to octreotide LAR or lanreotide ATG in patients with advanced, well-differentiated GEP-NET. Patients who experience progressive disease in the randomized part of the study may proceed to an open-label extension part with intensified treatment with CAM2029.
