Health condition
Health condition(s) or problem(s) studied:
Iron deficiency.

Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, ferrous sulfate and vitamin C is an iron supplement indicated for the prevention and treatment of iron deficiency.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the test formulation of ferrous sulfate/sodium ascorbate (1 x 325mg /562.4 mg) on one occasion and the innovator formulation of ferrous sulfate/sodium ascorbate (1 x 325mg /562.4 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of ferrous sulfate/sodium ascorbate.

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 for 24 hours after dosing.

Standard low iron and low fat meals will be consumed at the Clinical Site with no additional food intake allowed. The meal plan has been designed by a Nutritionist with daily iron content approximately 7mg and fat content approximately 16-21% of total energy per day. 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.

Comparator / control treatment
Single dose, crossover study design whereby each participant receives the test formulation of ferrous sulfate/sodium ascorbate (1 x 325mg/562.4 mg) on one occasion and the innovator formulation of ferrous sulfate/sodium ascorbate (1 x 325mg/562.4 mg) on one occasion with each dose seperated by a one week washout period. The comparator/control for this trial is the innovator formulation of ferrous sulfate/sodium ascorbate.

Outcomes
Primary outcome [1] 304731 0
To compare the bioavailability of ferrous sulfate/sodium ascorbate (as summarised by Cmax and AUC) for the formulation. All plasma samples will be assayed for ferrous sulfate using one fully validated colorimetric 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, the Section Head - Trials and Regulatory Affairs. or their delegates. The Trial Physician and Principal Investigator are completely blinded and do not know what treatments are allocated to each subject who has been deemed eligible for participation. Allocation concealment to each formulation is completed by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
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. Allocation of the subject number is completed by simple randomisation using a randomisation table created by computer software.
