ListOutcomeTime frameDescription
PrimaryNumber of Participants With Treatment-emergent Adverse Event(s) (TEAEs)Baseline through Day 90
Treatment-emergent adverse events (TEAE) were defined as any untoward medical occurrence in a subject administered study drug that does not necessarily have a causal relationship with the treatment and were collected from the time of first dose through end of study (day 90). In particular, audiometric and otoscopic TEAEs were recorded per the American Speech-Language-Hearing Association (ASHA) guidelines.
SecondaryCmaxData points taken pre-dose and 0.5, 1, 2, 4, 8, 24 hours post-doseMaximum concentration (Cmax) of FX-322 (Laduviglusib and Sodium Valproate) directly from individual concentration-time data
SecondaryTmaxData points taken pre-dose and 0.5, 1, 2, 4, 8, 24 hours post-doseTime to reach maximum concentration of FX-322 (Laduviglusib and Sodium Valproate) directly from individual concentration-time data
SecondaryAUClastData points taken pre-dose and 0.5, 1, 2, 4, 8, 24 hours post-doseArea under the concentration-time curve of FX-322 (Laduviglusib and Sodium Valproate) from time zero to the time of the last quantifiable concentration, calculated using the linear trapezoidal rule
Secondaryt1/2Data points taken pre-dose and 0.5, 1, 2, 4, 8, 24 hours post-doseThe observed terminal elimination half-life of FX-322 (Laduviglusib and Sodium Valproate)

Pharmacokinetic Analysis Set = Subjects in the Safety Analysis Set with plasma concentrations above the limit of quantification. Concentration-time data below the limit of quantification (BLQ) were treated as zero. The values of 4 of 7 subjects in the low dose group and 2 of 8 subjects in the high dose group were BLQ and were thus excluded from the PAS for t1/2 as those values could not be calculated.
