Brief Summary:
Debio 1450 is metabolised mainly by CYP3A4, therefore inhibitors of CYP3A4 have the potential to raise Debio 1450 plasma concentrations. Hence, it is important to determine the effect of CYP3A4 inhibition by itraconazole on the Pharmacokinetics of Debio 1450.

    An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. A Serious Adverse Event (SAE) is any experience that suggests a significant hazard, contraindication, side effect or precaution that: results in death, is life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or is medically significant.
