Evaluation of the Pharmacokinetics of Abiraterone Acetate and Abiraterone Following Single-Dose Administration of Abiraterone Acetate to Healthy Subjects.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectiveFollowing oral administration of abiraterone acetate, the parent compound abiraterone acetate is rapidly metabolized to abiraterone. To our knowledge, bioanalytical methods to date have not been able to detect the parent compound in human plasma, and bioassay was only performed on the metabolite. A highly sensitive bioanalytical method was developed and validated to measure plasma concentrations of the parent compound. In this study, both analytes were assayed and used to evaluate the full pharmacokinetic profile of abiraterone acetate tablets.
methodsThis was an open-label, single-dose, one-period, one-treatment, pharmacokinetic study performed in 18 healthy subjects. Each subject was administered four tablets (corresponding to a total dose of 1000 mg) of abiraterone acetate. Blood samples for pharmacokinetic analysis were collected up to 60 h post-dose. Subjects' plasma concentrations for abiraterone acetate were assayed using highly sensitive validated bioanalytical methods with a lower limit of quantitation (LLOQ) of 0.5 pg/ml for abiraterone acetate and 0.1 ng/ml for abiraterone. Safety assessments were performed throughout the study.
resultsThe pharmacokinetic results for abiraterone acetate showed a mean for the maximum plasma concentration (C
conclusionThe ability to detect the low plasma abiraterone acetate concentrations, in addition to abiraterone, resulted in a complete characterization of the pharmacokinetics of abiraterone acetate that was not possible with other analytical methods that only measured the metabolite. The development of new bioanalytical methods such as these will allow for a more thorough understanding of the pharmacokinetics of abiraterone acetate, and this, in turn, can have an impact on both future examinations into abiraterone acetate pharmacokinetic behaviour and the evaluation of its generic formulations.
