Overview

May support no dose adjustment with CYP inhibitors in chronic liver disease; leaves open confirmation in larger trials.

Structured PICO

Does avatrombopag require dose adjustment when co-administered with CYP3A and CYP2C9 inhibitors in patients with chronic liver disease?

P
Population
Patients with chronic liver disease (CLD) and thrombocytopenia
I
Intervention
Avatrombopag 40 and 60 mg for 5 days with concomitant CYP3A and CYP2C9 inhibitors
C
Comparator
Avatrombopag without concomitant CYP3A and CYP2C9 inhibitors
O
Outcome
Pharmacokinetics (PK) of avatrombopag and PK/PD relationship between plasma avatrombopag concentrations and platelet countsurrogate

Dose adjustment of avatrombopag is not necessary when co-administered with CYP3A and CYP2C9 inhibitors in patients with chronic liver disease due to comparable platelet count elevations and limited treatment duration.

Cite This Study

Nomoto et al. (2018) studied Chronic liver disease with thrombocytopenia. Avatrombopag with concomitant CYP3A and CYP2C9 inhibitors vs. Avatrombopag without concomitant CYP3A and CYP2C9 inhibitors was evaluated on Platelet count elevation and pharmacokinetics. Avatrombopag 40 and 60 mg for 5 days showed comparable platelet elevation with and without CYP3A/CYP2C9 inhibitors, with <10% of patients exceeding 200×10^9/L platelets.
