Phase 1
Completed
Conditions
Healthy
Interventions
Registration Number
NCT05338502
Lead Sponsor
Eli Lilly and Company
Brief Summary

The main purpose of this study is to learn about how H2 antagonist (ranitidine) and proton pump inhibitor (PPI) (omeprazole) affect Selpercatinib in healthy participants. Information about safety and tolerability will be collected. The study will last up to about 9 weeks, inclusive of screening period.

Primary Outcome Measures

Pharmacokinetics (PK): Area Under the Concentration-time Curve, From Time 0 to the Last Observed Non-zero Concentration (AUC0-t) of SelpercatinibPK: Pre-dose and 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 post Selpercatinib dose on Day 1 - Period 1, Day 12 - Period 2, and Day 23 - Period 3

PK: AUC0-t of Selpercatinib. The analysis of variance (ANOVA) model was performed on the natural log (ln)-transformed PK parameters and included calculation of geometric least squares (LS) means and the difference between treatment geometric LS means, as well as their corresponding 90% confidence intervals (CIs). The ratios of geometric LS mean and 90% CI for the ratio of the PK parameter for each comparison was constructed using the exponentiation of the difference and the CIs from the ANOVA analyses.

PK: Area Under the Concentration-time Curve From Time 0 Extrapolated to Infinity (AUC0-inf) of SelpercatinibPK: Pre-dose and 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 post Selpercatinib dose on Day 1 - Period 1, Day 12 - Period 2, and Day 23 - Period 3

PK: AUC0-inf of Selpercatinib. The ANOVA model was performed on the natural log (ln)-transformed PK parameters and included calculation of geometric LS means and the difference between treatment geometric LS means, as well as their corresponding 90% CIs. The ratios of geometric LS mean and 90% CI for the ratio of the PK parameter for each comparison was constructed using the exponentiation of the difference and the CIs from the ANOVA analyses.
