Description of intervention(s) / exposure
600mg or 800mg AVX754 (a new drug treatment of HIV) for 48 weeks.

This study is a phase IIb randomised, double-blind, multi-centre, dose-ranging, controlled parallel group study where lamivudine is the comparator. The study will enrol approximately 60 patients who will be followed for 48 weeks. The study will measure how safe and effective two doses of AVX754 (a new drug for the treatment of HIV) (600mg or 800mg) is compared to 150mg of lamivudine in treating HIV-1 infected people who have failed treatment with lamivudine.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by fax. The study investigators and patients are blinded to randomisation allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation schedule is generated by computer software that incorporates a standard procedure for generating randomisation codes. Subjects randomised in a 1:1:1 ratio. Two-part computer-generated labels are used to blind the investigational product.
