Pharmacokinetics of Posaconazole (Noxafil®) as Prophylaxis for Invasive Fungal Infections (PIRAÑA)

December 13, 2019 updated by: Radboud University Medical Center
This study evaluates the the pharmacokinetics of posaconazole (new solid oral and IV) given as prophylaxis to patients who are at risk for developing fungal infections after receiving conditioning therapy (except strictly non-myeloablative (NMA)) for allogeneic Stem Cell Transplant (SCT), remission induction chemotherapy for acute myeloid leukemia (AML) or myelo dysplastic syndrome (MDS) or being treated for severe graft versus host disease (GvHD) and determines the impact of mucositis on the pharmacokinetics of posaconazole new solid oral.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In 2014, the new intravenous and solid oral formulation of posaconazole were marketed. This offers new treatment possibilities, specifically in patients previously unable to attain adequate exposure to posaconazole solution. To the opinion of the researchers, only limited data are available on the pharmacokinetics (PK) of the new formulations of posaconazole, however, these use strictly selected patients or healthy volunteers, but more importantly, specific aspects related to the PK remain unsolved. Despite the fact that adequate exposure is attained using the new solid oral formulation, it is hypothesized that oral bioavailability of posaconazole may be impacted during mucositis. Whether mucosal barrier injury impacts the absorption of posaconazole or alters presystemic clearance is still unknown. Therefore, it seems prudent to conduct a trial in a group of patients that will experience a severe degree of mucositis to identify changes in absorption of posaconazole and resolving the impact of various stages of mucositis on the PK of posaconazole by linking PK of posaconazole to markers of mucositis (citrulline). This research may also serve as a model for other drugs and allows for direct translations in improving patient care. For this purpose it is needed to determine the PK using both IV and PO dosing of posaconazole.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Outcome Measure
Measure Description
Time Frame
exposure to posaconazole (Area Under the Curve) when administered intravenously and orally (tablet formulation)
Time Frame: day 7, day 12 and day 16
Plasma samples drawn on t=0 (pre-dose), 0.5, 1 (just prior to end of infusion), 2, 3, 4, 6, 8, 10, 12, 18 and 24 hours post infusion or post intake will be taken op day 7, day 12 and day 16 to determine posaconazole concentrations. Area Under the Curve of two routes of administration and two dosing regimens will be determined.
day 7, day 12 and day 16
impact of mucositis (determined by citrulline concentrations) on exposure (AUC) to posaconazole.
Time Frame: day 7, day 12 and day 16
Full pharmacokinetic curve (plasma samples drawn on t=0 (pre-dose), 0.5, 1 (just prior to end of infusion), 2, 3, 4, 6, 8, 10, 12, 18 and 24 hours post infusion or post intake) will be taken op day 7, day 12 and day 16 (posaconazole).
