Multicountry, Multicenter Post-Marketing Observational Study of Clinical, Biological and Virological Outcomes, Compliance and Tolerability of Kaletra® in Routine Clinical Use

KaleEAST is a non-interventional, post-marketing observational study (PMOS) in which lopinavir/ritonavir is prescribed in the usual manner in accordance with the terms of the local marketing authorization with regards to dose, population and indication. No additional procedures (other than the standard of care) are to be applied to the patients. The KaleEAST PMOS was conducted in a prospective, single-arm, multicountry, multicenter format. The study was carried out in two (2) parts: the first part was initiated in 2004 with the lopinavir/ritonavir capsule formulation, the second part started in 2006 after the lopinavir/ritonavir tablets had become available in the participating countries. The aim of this post-marketing observational study was to obtain further data on clinical, biological, and virological outcomes, compliance and tolerability of Kaletra®-containing regimen during routine clinical use in the participating countries.
