Es, Inc.; Ernesto Aycardi, Xenon Pharmaceuticals Inc. NBI-921352 (also called XEN901), a potent and highly selective Nav1.6 inhibitor, is becoming evaluated for the remedy of SCN8A developmental and epileptic encephalopathy (SCN8A-DEE) as well as other forms of epilepsy. In Adenosine Kinase custom synthesis Clinical development, NBI-921352 is going to be utilised adjunctively with other antiseizure drugs (ASMs), several of which are potent cytochrome P450 (CYP) inducers. Phenytoin, a robust CYP3A4 inducer and moderate CYP1A2/CYP2C19 inducer, is often a frequently utilized ASM and recognized by the FDA as an index P450 inducer. For that reason, it was chosen for the current study to evaluate the influence of phenytoin CYP induction around the pharmacokinetics (PK) of NBI-921352. In this single-center, open-label, randomized study, healthier subjects received single oral doses of NBI-921352 (100 mg) after overnight fasts on days 1 and 12. Phenytoin (100 mg 3 each day) was administered on day three by way of towards the morning of day 12. Blood Apical Sodium-Dependent Bile Acid Transporter Source samples have been obtained pre-dose and as much as 48 h post-dose to determine NBI-921352 plasma concentrations using a validated bioanalytical method. Phenytoin PK samples have been collected prior to morning doses on day three and days 72 to evaluate trough levels. Security evaluations included adverse occasion (AE) monitoring. Of 17 evaluable subjects, 14 (82.4 ) had been male and 17 (one hundred ) were white; mean age was 41.six years. The geometric imply ratio (GMR) with 90 confidence interval (CI) for maximumASENT2021 Annual Meeting Abstractsconcentration (Cmax) of NBI-921352 plus phenytoin versus NBI-921352 alone was 122 (9162 ). Having said that, the GMR (90 CI) for NBI-921352 region under the curve (AUC0-inf) was 93 (8205 ), indicating that phenytoin didn’t have an effect on total systemic NBI-921352 exposure. Median time to maximum plasma concentration (Tmax) of NBI-921352 was 1 h, with or devoid of phenytoin. Terminal elimination half-life (T1/2) of NBI-921352 alone (10 h) was comparable to NBI-921352 with phenytoin (eight h). Phenytoin trough levels reached apparent steady-state by day ten. No deaths, significant AEs, or discontinuations as a consequence of AEs occurred during the study. The most frequent treatmentrelated AEs were dizziness, headache, and nausea, all of which have been usually mild. These findings recommend that no dose adjustment will likely be necessary for co-administration of NBI-921352 with phenytoin or other robust CYP3A4 inducers and/or moderate CYP1A2/CYP2C19 inducers.
