Anagrelide vs. Hydroxyurea - Efficacy and Tolerability Study in Patients With Essential Thrombocythaemia (ANAHYDRET)

October 5, 2010 updated by: AOP Orphan Pharmaceuticals AG

A Single Blind, Multi-centre, Randomised Multinational Phase III Study to Compare the Efficacy and Tolerability of Anagrelide vs Hydroxyurea in Patients With Essential Thrombocythaemia

Study AOP 03-007 was designed as a pivotal study to test, if Anagrelide (Thromboreductin®)was not inferior to HU with respect to efficacy in patients with ET. This approach to demonstrate non-inferiority was based on the following decision points:

• ET is a rare disease and recruitment of large patient number (> 1600) to prove superiority was not considered possible.

. It was decided to recruit only treatment naïve high risk patients to avoid pre-treatment bias, which further limited the number of patients eligible for the study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

Ages Eligible for Study

14 years and older (Adult, Older Adult)
