Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Health condition
Health condition(s) or problem(s) studied:
Bioequivalence study conducted in healthy volunteers comparing two formulations of anagrelide with no health condition or problem studied.

Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, anagrelide is a platelet-reducing agent . It is used to decrease the risk of blood clots in patients who have thrombocythaemia (too many platelets in the blood). It works to decrease production of platelets in the blood.. 296457 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the test formulation of anagrelide (1 x 0.5 mg) on one occasion and the innovator formulation of anagrelide (1 x 0.5 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of anagrelide.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose).
Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored and for 8 hours after dosing.

Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing.

Pre and post study laboratory tests will be completed to assess the health of participants along with HIV, Hepatitis and drugs of abuse testing.

Each dose will be taken orally with 240 ml of water at ambient temperature. Medication must be swallowed whole and a mouth check will be conducted to ensure the medication has been taken as directed.

Outcomes
Primary outcome [1] 296329 0
To compare the bioavailability of anagrelide (as summarised by Cmax and AUC) for the formulation. All plasma samples will be assayed for anagrelide using one fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All formulations will be labelled as Formulation A and B. The identification of each treatment will only be known to the Managing Director and the Section Head - Trials and Regulatory Affairs.

Each participant will be identified by a 3 digit screening number and a 2 digit subject number. The screening number will be issued once the participant has given written consent to participate in the study and the two digit subject number (randomisation number) after acceptance into the study
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation list will be prepared using a computer program for a balanced two-way crossover design.
Masking / blinding
