A Drug-Drug Interaction Study to Evaluate the Effect of Vapendavir on the Pharmacokinetics of Midazolam in Healthy Male and Female Volunteers

29 mai 2018 mis à jour par: Biota Scientific Management Pty Ltd

A Phase 1, Randomized, Open-Label Study to Evaluate the Effect of Vapendavir (BTA798) on the Pharmacokinetics of Orally Administered Midazolam, a CYP3A4 Substrate, in Healthy Male and Female Volunteers

The primary aim of this Phase 1 study is to evaluate the effect of vapendavir daily doses of 528 mg daily (QD) and 264 mg twice daily (BID) on the pharmacokinetic (PK) profile of midazolam, a cytochrome (CYP) 3A4 substrate. Additionally, the effect of midazolam on the PK profile of vapendavir, a PK profile comparison of vapendavir in males and females, as well as the safety of vapendavir will also be assessed.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Vapendavir 528 mg QD
Twelve subjects (6 male and 6 female) will receive 528 mg vapendavir (achieved with four 132 mg vapendavir capsules) QD in the morning for seven days

All twenty four subjects will receive 5 mg midazolam syrup at four different time points during the study for a total of four non-subsequent dosing days.

  • On Study Days 0 and 12, subjects will receive only 5 mg midazolam syrup dosed in the morning.
  • On Study Days 6 and 9, subjects will have 5 mg midazolam syrup co-administered with their assigned dose of vapendavir in the morning. Co-administration of midazolam will not occur at the time of the evening dose for Group B.
Twelve subjects (6 male and 6 female) will receive 528 mg vapendavir (achieved with four 132 mg vapendavir capsules) QD in the morning for seven days
Expérimental: Vapendavir 264 mg BID
Twelve subjects (6 male and 6 female) will receive 264 mg vapendavir (achieved with two 132 mg vapendavir capsules) BID daily as divided dose given in the morning and evening 12 hours apart for seven days.

All twenty four subjects will receive 5 mg midazolam syrup at four different time points during the study for a total of four non-subsequent dosing days.

Description de la mesure
Délai
The Effect of Vapendavir on the PK Profile of Midazolam
Délai: End of Study (up to 46 weeks in duration)

To evaluate the effect of vapendavir daily dose of 264 mg BID on the PK profile of midazolam, a CYP3A4 substrate. The primary outcome will be evaluated through a series of analyses of PK parameters including:

  • for midazolam including maximum observed plasma concentration (Cmax)
  • time at which Cmax was observed (Tmax)
  • plasma concentration at the end of the dosing interval (Ctau)
  • area under the plasma concentration-time curve from time 0 to the last measurable plasma concentration (AUC0-last)
  • area under the plasma concentration-time curve from time 0 to the end of the dosing interval (AUC0-tau)
  • area under the plasma concentration-time curve from time 0 extrapolated to infinity (AUC0-inf)
  • elimination half-life (t1/2)
  • apparent oral clearance (CL/F)
  • apparent oral volume of distribution (Vz/F).

  • plasma concentration at the end of the dosing interval (Ctau)
  • area under the plasma concentration-time curve from time 0 to the last measurable plasma concentration (AUC0-last)

Délai: End of Study (up to 46 weeks in duration
To evaluate the safety of vapendavir. This will be accomplished by assessing adverse events, clinical laboratory tests (including blood chemistry, hematology with differential and urinalysis), physical exams, ECG assessments, vital sign assessments and concomitant medications.
