MONONOFU, a multicenter, randomized, double-blind, placebo-controlled phase 2 study of Japanese patients with migraine, was pivotal for lasmiditan approval in Japan. However, treatment-emergent adverse events (TEAEs) were more common than in global studies. A detailed safety profile would assist patient management.

Safety assessments in MONONOFU included specific terms reported, frequency, severity, time to onset, duration, TEAE management, common TEAE risk factors, and TEAE–efficacy associations.

Of 846 participants, 691 were assessed for safety. The proportion of participants reporting ≥1 TEAE was 23.4% with placebo and 70.9% with lasmiditan; 87.3% of TEAEs with lasmiditan were mild. The most frequent TEAEs with lasmiditan, dizziness (39.4%) and somnolence (19.3%), started ≤1 hour postdose (median durations: 2.5 and 3.3 hours, respectively). Higher lasmiditan dose, but not patient factors including body size, was identified as a clinically meaningful predictor of dizziness and somnolence. There were no adverse consequences of neurological TEAEs, which did not appear to adversely affect lasmiditan efficacy.

In the MONONOFU study, TEAEs appeared typically mild, transient, and self-limiting. Lasmiditan may represent a useful and well-tolerated acute treatment option for smaller (body mass index <30 kg/m2) patients and Asian patients with migraine.
