A Drug-Drug Interaction Study of CYP3A4 Inhibition and Pan-CYP Induction on APX001

May 16, 2024 updated by: Basilea Pharmaceutica

A Phase 1, Open-Label, Fixed-Sequence, Drug-Drug Interaction Study of APX001 to Evaluate the Effects of CYP3A4 Inhibition and Pan-CYP Induction in Two Parallel Groups of Healthy Male and Female Subjects

This is a Phase 1, open-label study to evaluate the drug-drug interaction potential of a strong CYP3A4 inhibitor (itraconazole) and a pan-CYP inducer (rifampin) on APX001 in two parallel groups of healthy subjects.
