Intervention/exposure
Study type
Interventional
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.

Treatment: Drugs
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
Placebo

Outcomes
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] 287429 0
Evaluated daily over 10 days dosing, and continuing to day 20 (10 days post dose).
Secondary outcome [1] 298127 0
Evaluate the pharmacokinetics of 400mg BIT225 administered daily on days 1 and 10, and twice daily on days 2 to 9 (for 10 consecutive days) in patients with HIV-1 infection
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. On day 5 a sample will be collected predose and on day 12 48 hours post dose.
Secondary outcome [2] 298128 0
Evaluate the antiviral activity of BIT225 administered for 10 consecutive days in patients with HIV-1 infection that are antiretroviral therapy naive. Change from baseline plasma viral load will be measured using the Roche COBAS TaqMan HIV-1 test, i.e. PCR.
Timepoint [2] 298128 0
Plasma HIV RNA will be measured on days 1, 2, 5, 10, 11 and 20
Secondary outcome [3] 298129 0
Evaluate BIT225 levels in cerebrospinal fluid will be measured using a validated liquid chromatography tandem mass spectrometry method.
Timepoint [3] 298129 0
Day 9 or 10, depending on the availability of the participant.

4. Plasma HIV-1 RNA > 5,000 copies/mL within 30 days before Entry (Day 1) by any FDA-approved test for quantifying HIV-1 RNA at any certified laboratory.

5. CD4+ count > 350 cells/mm3 within 30 days before Entry (Day 1).

6. For women of reproductive potential, negative serum or urine pregnancy test with a sensitivity of < 25 miU/mL at Screening (baseline) and Day 1.

Subjects who are not of reproductive potential (women who have been post-menopausal for at least 24 consecutive months or have undergone hysterectomy, salpingotomy, and/or bilateral oophorectomy or men who have documented azoospermia) are eligible without requiring the use of contraceptives. Acceptable documentation of sterilization and menopause is the woman’s self-reported history of surgical sterilization, menopause or male partner’s asoospermia. Follicle stimulating hormone-release factor (FSH) measurement can be used to document menopausal range.

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.
