Drug-drug Interaction Study Between Lopinavir/Ritonavir and Isavuconazole

February 20, 2015 updated by: Astellas Pharma Global Development, Inc.

A Phase 1, Open-Label, Parallel Study to Evaluate the Effect of Multiple Doses of Isavuconazole on the Pharmacokinetics of Multiple Doses of Lopinavir/Ritonavir and the Effects of Lopinavir/Ritonavir on the Pharmacokinetics of Multiple Doses of Isavuconazole in Healthy Adult Subjects

The purpose of this two part study is to assess the effect of multiple doses of isavuconazole on the pharmacokinetics of multiple doses of lopinavir/ritonavir and the effect of multiple doses of lopinavir/ritonavir on the pharmacokinetics of isavuconazole.

Part 1 of the study includes 12 subjects randomized to receive either isavuconazole alone or isavuconazole in combination with lopinavir/ritonavir. The purpose of Part 1 is to evaluate safety and tolerability and to establish the effect of multiple doses of lopinavir/ritonavir on isavuconazole.

Part 2, if initiated, includes 54 subjects randomized to receive isavuconazole alone, lopinavir/ritonavir alone, or isavuconazole in combination with lopinavir/ritonavir.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
