Switching Patients with Schizophrenia from Intramuscular Paliperidone Palmitate Once Monthly to TV-46000, a Long-Acting Subcutaneous Antipsychotic: Population Pharmacokinetic-Based Strategies.

ABSTRACT:

Introduction

Pharmacokinetic differences between long-acting injectable antipsychotic (LAI) formulations, combined with a lack of clinical switch studies, contribute to clinician uncertainty when transitioning between LAIs. This analysis employed a population pharmacokinetic (popPK) modeling approach to characterize dosing conversions and switching strategies from intramuscular paliperidone palmitate once monthly (PP1m) to TV-46000, a long-acting subcutaneous formulation of risperidone, once monthly (q1m), with a secondary analysis of PP1m to TV-46000 every 2 months (q2m).

Methods

For PP1m and TV-46000, concentration-time profiles for paliperidone and TV-46000 total active moiety (TAM; risperidone + paliperidone) were simulated on the basis of published popPK models with vir
