The Effects of Denosumab on the Pharmacokinetics (PK) of Midazolam

9 juli 2018 uppdaterad av: Amgen

The Effects of Denosumab on the Pharmacokinetics (PK) of Midazolam, a Cytochrome P450 3A4/P-gp (CYP3A4) Substrate, in Postmenopausal Osteoporotic Women

This is a multi-center, open-label, drug-drug interaction study in postmenopausal women with osteoporosis.

Studieöversikt

Status

Avslutad

Detaljerad beskrivning

Approximately 27 subjects (Group A: 18; Group B: 9) will receive a 2 mg oral dose of midazolam on day 1 followed by a 24 hour PK collection. Subjects randomized to Group A will receive a single 60 mg subcutaneous (SC) dose of denosumab on day 2 administered in the abdomen. On study day 16, another 2 mg oral dose of midazolam will be administered to all subjects (Groups A and B) followed by a 24 hour PK collection. The primary analysis to determine the effect of denosumab on the PK of midazolam will be based on data from subjects in Group A only.
