Study type
Description of intervention(s) / exposure
BIT225, 400mg oral, once daily on days 1 and 10, and twice daily on days 2 to 9. BIT225 is supplied as a powder to be suspended immediately before use in 25mL of OraSweet Sugar Free, a taste masking solution. After administration the patient will be asked to drink 240mL of non-carbonated water, which is poured into the dosing cup and swirled around to collect the remaining powder, before drinking.

Comparator / control treatment
Placebo is 400mg of lactose to be suspended immediately before use in 25mL of OraSweet Sugar Free, a taste masking solution. After administration the patient will be asked to drink 240mL of non-carbonated water, which is poured into the dosing cup and swirled around to collect the remaining powder, before drinking.
Control group

Primary outcome [1] 287429 0
Evaluate the safety and tolerability of 400mg BIT225 twice daily compared to placebo in patients with human immunodeficiency virus-1 (HIV-1) infection that are antiretroviral niave. Safety and tolerability will be assessed by comparison to placebo of treatment emergent untoward medical changes, e.g. nausea, vomitting or loss of weight, and changes in clinical laboratory assessments, vital signs, and ECG.

Timepoint [1] 298127 0
Pharmacokinetic samples will be collected on Days 1, 2 and 5, then on days 10, 11 and 12. The concentration of BIT225 in plasma will be measured using a validated liquid chromatography tandem mass spectrometry method.
On days 1 and 10 samples will be collected 30-60 minutes pre-dose, then 30, 60, 90 and 120 minutes, and 3 and 4 hours post dose. On day 10 additional samples will be taken at 6, 8, 10 and 12 hours post dose. On days 2 and 11 a sample will be taken at 24 hours post dose.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be assigned to a sequentially numbered treatment in accordance with the randomisation schedule following confirmation of eligibility on day 1. An unblinded pharmacist at the site will dispense the study medication to the blinded site staff according to the randomisation schedule. The dispensed medication will carry the participant's unique study number.

Brief summary
Biotron is developing a novel inhibitor of HIV-1, called BIT225. This early phase trial will assess the safety of BIT225 in patients with HIV-1 infection who have not received any other therapy for HIV-1. It will also assess how well BIT225 is tolerated, the level of BIT225 in the blood following oral administration, and how well BIT225 performs at reducing HIV-1 levels in the blood.
