Résumé
Following European guidelines, patients with aggressive metastatic or locally advanced, non-resectable, duodeno-pancreatic (DP) neuroendocrine tumours (NETs) should receive systemic combination chemotherapy until progression. Aggressive disease is defined as progressive and/or symptomatic metastases with or without significant hepatic invasion (>30-50%), and/or bone metastases. This academic randomised, double-blind, placebo-controlled phase II study aims to evaluate lanreotide autogel 120 mg (LAN) as maintenance treatment after at least 2 months of first-line treatment (L1) in aggressive G1-G2 DP-NET. Patients were randomly assigned in a 1:1 ratio to receive LAN or placebo (PBO), every 28 days, until progression or toxicity. The primary end-point was progression-free survival (PFS) at 6 months. Among the 118 planned patients, 53 were included. Of these, 81.1% had a G2 tumour, and 90.6% had metastatic disease. L1 therapy consisted of chemotherapy (96.8%). Median duration of L1 was 4.6 months (range: 2.0-7.7). At the time of randomisation, 81.1% of patients had stable disease. Median follow-up was 27.0 months (95% CI: 19.5; 31.2). PFS at 6 months was 73.1% (90% CI: 55.3; 86.6) in LAN versus 54.2% (90% CI: 35.8; 71.8) in PBO. Median PFS was 19.4 months (95% CI: 7.6; 32.6) and 7.6 months (95% CI: 3.0; 9.0), respectively. Median overall survival was 41.9 months in PBO and was not reached in LAN. The toxicity profile was mainly grade 1-2 expected toxicities. The encouraging results of lanreotide autogel 120 mg as a maintenance treatment after L1 in aggressive G1/2 DP-NET should be confirmed. NCT02288377 (clinicaltrials.gov).

BACKGROUND
Following European guidelines, patients with aggressive metastatic or locally advanced, non-resectable, duodeno-pancreatic (DP) neuroendocrine tumours (NETs) should receive systemic combination chemotherapy until progression. Aggressive disease is defined as progressive and/or symptomatic metastases with or without significant hepatic invasion (>30-50%), and/or bone metastases.
METHODS
This academic randomised, double-blind, placebo-controlled phase II study aims to evaluate lanreotide autogel 120 mg (LAN) as maintenance treatment after at least 2 months of first-line treatment (L1) in aggressive G1-G2 DP-NET. Patients were randomly assigned in a 1:1 ratio to receive LAN or placebo (PBO), every 28 days, until progression or toxicity. The primary end-point was progression-free survival (PFS) at 6 months.
RESULTS
Among the 118 planned patients, 53 were included. Of these, 81.1% had a G2 tumour, and 90.6% had metastatic disease. L1 therapy consisted of chemotherapy (96.8%). Median duration of L1 was 4.6 months (range: 2.0-7.7). At the time of randomisation, 81.1% of patients had stable disease. Median follow-up was 27.0 months (95% CI: 19.5; 31.2). PFS at 6 months was 73.1% (90% CI: 55.3; 86.6) in LAN versus 54.2% (90% CI: 35.8; 71.8) in PBO. Median PFS was 19.4 months (95% CI: 7.6; 32.6) and 7.6 months (95% CI: 3.0; 9.0), respectively. Median overall survival was 41.9 months in PBO and was not reached in LAN. The toxicity profile was mainly grade 1-2 expected toxicities.
CONCLUSIONS
The encouraging results of lanreotide autogel 120 mg as a maintenance treatment after L1 in aggressive G1/2 DP-NET should be confirmed.
