PROVEN FOR PFS IN PATIENTS WITH GEP-NETs1,2
Somatuline® Depot reduced the risk of tumor progression by greater than half vs placebo1,2
Somatuline Depot improved PFS for patients with GEP-NETs – studied in adult patients with unresectable, well- or moderately-differentiated, locally advanced or metastatic
GEP-NETs1,2
- The median PFS for Somatuline Depot was not yet reached at 22 months (95% CI: NE, NE) compared with 16.6 months for placebo (95% CI: 11.2-22.1)1
- Number of events (N=204): Somatuline Depot 32 (31.7%) vs placebo 60 (58.3%)1
CI=confidence interval; FDA=Food and drug Administration;
GEP-NET=gastroenteropancreatic neuroendocrine tumor; NE=not estimable;
PFS=progression-free survival.
NE=Not reached at 22 months.1

Study design and patient population information
CLARINET: A Phase 3 trial of an SSA powered for PFS and one of the largest studies of the antitumor effect in patients with GEP-NETs1,2
The majority (84%) of patients in CLARINET had not received prior pharmacologic therapy for GEP-NETs. Some patients (16%) received prior therapy.2
Patients were excluded if they received:2
- An SSA at any time, unless they received it >6 months prior to study entry and for <15 days
- Interferon, chemoembolization, or chemotherapy: <6 months prior to study entry
*CLARINET=Controlled Study of Lanreotide Antiproliferative Response In NeuroEndocrine Tumors.2
†Administered every 28 days by deep subcutaneous injection. Follow-up visits occurred at Weeks 12, 24, 36, 48, 72, 96.2
‡Assessed by a central independent radiological review in accordance with the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0.1,2
Disease characteristics
Progression-free survival studied in a comprehensive and robust patient population2
CLARINET trial included patients with unresectable, well- to moderately differentiated, locally advanced or metastatic GEP-NETs, a range of hepatic tumor loads, and varying primary tumor locations (pancreas, midgut, or hindgut).2
