Safety, Tolerability and Pharmacokinetics of Single Rising Oral Doses and Multiple Oral Doses of BI 1323495 Versus Placebo in Healthy Male Japanese Subjects Genotyped as Poor and Extensive Metabolizers of UGT2B17 (Single-blind, Randomised, Placebo-controlled [Within Dose Groups] Trial), Including an Investigation of Drug-drug Interaction With Itraconazole in Healthy Male Subjects Genotyped as Poor Metabolizers of UGT2B17 (an Open-label, Two-period, Fixed Sequence Trial)

1405-0003

The main objective of the single-rising dose (SRD) part and the multiple rising dose (MD) part is to investigate safety, tolerability, pharmacokinetics and pharmacodynamics (for MD part only) following single rising doses and multiple oral doses of BI 1323495 in healthy male Japanese subjects genotyped as poor metabolizers (PM) and extensive metabolizers (EM) of UGT2B17. The main objective of the drug-drug interaction (DDI) part is to investigate the relative bioavailability of a single oral dose of BI 1323495 when given alone (treatment R) or in combination with itraconazole (treatment T) in healthy male subjects genotyped as PM of UGT2B17.
