cARdiotoxicity Profile of aBIraTeRone in prostAte Cancer : a pharmacoviGilancE Study (ARBITRAGE)

October 17, 2018 updated by: Joe Elie Salem, Groupe Hospitalier Pitie-Salpetriere

Cardiotoxicity of Abiraterone in the National French Pharmacovigilance Database and in the European Clinical Trials Database (EudraCT)

Abiraterone associated with prednisone is used in prostate cancer. Abiraterone is a selective small-molecule inhibiting cytochrome P450 17A1 (CYP17A1), a key enzyme in androgen synthesis.

CYP17A inhibition is also responsible for mineral corticosteroid related adverse events as hypokaliemia, fluid retention, and hypertension. Primary hyperaldosteronism is associated with cardiovascular toxicities such as atrial fibrillation and cardiac failure. Other androgen-deprivation therapies are not associated with increased mineral corticosteroid level.

This study investigates reports of cardiovascular toxicities for treatment including L02 (sex hormones used in treatment of neoplastic diseases), and G03 (sex hormones) used in prostate cancer in the French pharmacovigilance database and in the EudraCT database.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Due to its peculiar pharmacology, abiraterone is potentially associated with more cardiotoxicity as compared to other androgen-deprivation therapies. This study investigates the main characteristics of patients affected by cardiovascular side effects of which supraventricular arrhythmias (including atrial fibrillation, atrial flutter, supraventricular tachycardia), and cardiac failure imputed to drugs classified as L02, and G03 according to anatomical therapeutic chemical (ATC) classification. A causality assessment according to the World Health Organization-The Uppsala Monitoring Centre (WHO-UMC) is systematically applied.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Analysis of disproportionality of reports for cardiotoxicity associated with abiraterone as compared to enzalutamide by performing a case- non-case study

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
