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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, 3 period, partial replicate, reference scaled, crossover study design whereby each participant receives the test formulation of 240 mg Dimethyl (2E)-but-2-enedioate capsule on one occasion and the innovator formulation of 240 mg Dimethyl (2E)-but-2-enedioate capsule on two occasions with each dose separated by a one week washout period. The intervention for this trial is the test capsule formulation.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for water consumed with the dose).
Participants are required not to eat for 10 hours before receiving a standardised high fat content meal and to fast for approximately 4 hours after receiving each dose.

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 ( 1 x 240 mg) 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] 327794 0
To compare the bioequivalence of (E)-4-methoxy-4-oxobut-2-enoic-acid (as summarised by Cmax and AUC) for the formulation. All plasma samples will be assayed for (E)-4-methoxy-4-oxobut-2-enoic-acid using a fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.
Timepoint [1] 327794 0

Secondary outcome [1] 396615 0
Time to maximum peak concentration (Tmax) will be determined by plasma sample analysis. Tmax will be the time where the maximum concentration occurred in the sample points.

Study design
Purpose of the study
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.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each participant will be given 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. Sequence generation will be by using a simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
