Abstract 1162MO

Background

CLARINET FORTE assessed the efficacy and safety of increasing LAN 120 mg dose frequency from every (q) 28 days (standard) to q14 days in patients with a progressive pancreatic NET (panNET) or midgut NET.

Methods

A prospective, single-arm, open-label, exploratory, international phase II study in patients with a metastatic or locally advanced, unresectable, G1/2 panNET or midgut NET, with centrally assessed progression within the last 2 years while on a standard LAN regimen for ≥24 weeks. Planned recruitment was 50 patients per cohort. LAN 120 mg q14 days was administered for 48 (panNET) or 96 (midgut) weeks (or until centrally-assessed progressive disease, unacceptable toxicity/tolerability, or death), or longer if <25 events had occurred.

Results

In the panNET (N=48) and midgut NET (N=51) cohorts, respectively, median (95% confidence interval [CI]) progression-free survival (PFS, primary endpoint) was 5.6 (5.5; 8.3) and 8.3 (5.6; 11.1) months. Post-hoc subgroup analysis in the panNET cohort showed median (95% CI) PFS of 8.0 (5.6; 8.3) months in patients with Ki67 ≤10% (N=43), and 2.8 (2.8; 2.9) months in patients with Ki67 >10% (N=5). Disease control rate (DCR; proportion of patients with complete response, partial response or stable disease; 95% CI) in the panNET and midgut NET cohorts, respectively: Week 24, 43.8% (29.5; 58.8) and 58.8% (44.2; 72.4); Week 48, 22.9% (12.0; 37.3) and 33.3% (20.8; 47.9). Treatment-related adverse events (TRAEs) occurred in 37.5% and 51.0% of patients in the panNET and midgut NET cohorts, respectively; only one TRAE was G≥3 (panNET: fatigue [N=1], G3). The most common (≥10%) classes of TRAEs were gastrointestinal disorders (panNET, 25.0%; midgut NET, 37.3%) and general disorders/administration-site conditions (midgut NET, 13.7%). Of note, the following TRAEs occurred: hyperglycaemia (N=2), bile stones (N=1), steatorrhea (N=1).

Conclusions

LAN 120 mg q14 days in patients with panNETs or midgut NETs (progressive on standard LAN dose) produced promising PFS and DCR. In the pan-NET cohort, the outcome was more favourable in patients with Ki67 ≤10%. Safety was consistent with the known safety profile of LAN.
