COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

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:
Pharmacodynamic effects study conducted in healthy volunteers with no health condition or problem studied.

This study is being conducted in healthy volunteers who are not being treated for the conditions that anatabine citrate are indicated for. Anatabine citrate is a naturally occurring alkaloid found in the Solanaceae plant family. It is also the ingredient of a number of dietary supplements.

Study type
Description of intervention(s) / exposure
Single dose study where each participant receives one dose of anatabine citrate on one occasion. The dosage will be either 3 or 4 mg oral tablet based on body weight taken with 240 ml water. If the subject weighs less than or equal to 81.4 kg the dose given will be 3 mg. If the subject weighs 81.5 kg or above they will receive 4 mg. The intervention for this trial is the test formulation of anatabine citrate.

All subjects will receive their dosage and blood samples will be collected immediately prior to dosing and then one hour after dosing via venipuncture.

Subjects who meet the inclusion and exclusion criteria will be included in this study. Pre and post study laboratory tests will be performed along with an ECG and medical evaluation. A follow up visit will also be completed to assess for safety.

Primary outcome [1] 293913 0
To evaluate the pharmacodynamic effects of a single oral dose of anatabine citrate on the ex vivo expression/activity of pro-inflammatory mediators from activated peripheral blood mononuclear cells in healthy adult volunteers.

At Visit 2, blood samples will be drawn prior to study product administration and one hour (+/- 10 minutes) post-dosing for evaluation of PD measures. Blood samples may also be evaluated for anatabine levels, although formal pharmacokinetic evaluations will not be performed. PD assessments will include evaluation of the production of pro-inflammatory mediators from PBMCs stimulated ex vivo with LPS. Relationships between PD outcomes and anatabine will be explored. Serum concentrations of anatabine will be determined by validated LC/MS/MS analytical methods.

Study design
Purpose of the study
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is an open label, nonrandomised, uncontrolled study with one treatment.

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 will be issued after acceptance into the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Subjects will be accepted onto the study based on the order of enrollment. No randomisation programme will be used.
