Popis: | STUDY OBJECTIVES: To determine the time course and duration of common, early-onset treatment-emergent adverse events (TEAEs) associated with sodium oxybate (SXB) use in adults with narcolepsy. METHODS: These were post hoc analyses of two 8-week, randomized, double-blind, placebo-controlled trials. In SXB-15, participants (n = 246) received daily placebo (n = 60) or SXB (n = 186) initiated at 4.5 g. Participants assigned to SXB 6 or 9 g were titrated in 1.5-g increments. In SXB-22, participants entering on modafinil (n = 231) received placebo (n = 56), SXB (n = 55), modafinil (n = 63), or SXB and modafinil (n = 57). SXB was initiated at 6 g for weeks 1–4 and increased to 9 g for weeks 5–8. TEAEs reported more frequently in SXB-treated participants than placebo and in ≥5% of any SXB treatment group during week 1 were examined as TEAEs of interest. RESULTS: Dizziness and nausea met criteria as TEAEs of interest in both studies; headache also met criteria as a TEAE of interest in SXB-15. Incidence of new or worsened TEAEs was highest at week 1 (SXB-15: dizziness, 7.5%; headache, 7.5%; nausea, 5.9%; SXB-22: dizziness, 5.4%; nausea, 7.1%) and decreased over time in both studies. The longest median duration was reported for dizziness: 9.0 and 17.5 days in SXB-15 and SXB-22, respectively. Dizziness caused discontinuation in 2.2% and 3.6% of participants in SXB-15 and SXB-22, respectively; nausea caused discontinuation in 2.7% and 1.8%. CONCLUSIONS: Common early-onset TEAEs associated with SXB treatment were generally of short duration and their incidence decreased over time. These TEAEs accounted for few discontinuations overall.
