Clinical Trial Summary

This was a Phase 1, randomized, 2-period, 2-sequence, cross-over study designed to determine the effect of ALXN1840 on the metabolism of celecoxib, a sensitive cytochrome P450 2C9 (CYP2C9) substrate, in healthy male and female participants. The safety and tolerability of ALXN1840 were determined along with ALXN1840 pharmacokinetics (PK) in plasma as measured via total molybdenum with the coadministration of celecoxib.


Description:

The study was conducted as a randomized, 2-period, 2-sequence, cross-over study to determine the effect of a single dose of ALXN1840 (perpetrator) on the single-dose celecoxib (victim) kinetics in healthy male and female participants. The study had a Screening period (Day -28 to Day -2), two 11-day study periods (Day 1 to Day 11) with a minimum of 14 days between doses of celecoxib, and an End of Study Visit (Day 15 ± 2 days) after Period 2 dosing. Participants only reported to the clinical research unit (CRU) on the day prior to the first dose because they were kept in the CRU during the wash-out period due to coronavirus disease 2019. All participants received a single dose of celecoxib alone (Treatment A) and celecoxib coadministered with ALXN1840 (Treatment B) during the study, 1 in each treatment period. Based on randomization, participants were administered either Treatments A-B or Treatments B-A in each study period. The PK profile of ALXN1840 and celecoxib was determined by blood sampling following single-dose administration. In addition to PK sampling, safety and tolerability were assessed by monitoring adverse events, vital signs, 12-lead electrocardiograms, physical examinations, and laboratory parameters.
