About this study
Official title: A Phase 3, Open Label 96-week Extension Study of the Safety of Apricitabine in Treatment-experienced HIV-1 Infected Patients Who Have Completed Protocol AVX-301 or AVX-302 or Who Have Met the Criteria for Open-label Access to ATC Because of Virological Failure/Lack of Response
This study will examine the long term safety of apricitabine in HIV-1 infected patients from studies AVX-301 or AVX-302. Eligible patients are those who have either (a)completed studies AVX-301 or AVX-302; or (b)met the criteria for virological failure/lack of response, and consequently wish to withdraw early from studies AVX-301 or AVX-302.
Read the detailed description
The clinical study AVX-301 studies the efficacy and safety of 800mg and 1200mg BID ATC in combination with an optimized background in patients who are HIV-1 infected and have failed treatment with emtricitabine or lamivudine and have confirmed M184V/I mutation. Patients who do not achieve at least a 0.5 log10 copies/mL decrease in plasma HIV RNA by Week 16, or who experience a >1.0 log10 copies/mL increase (confirmed on two separate occasions at least one week apart) in plasma HIV RNA from nadir at or after Week 16, are eligible for screening for entry into this study. In addition, patients who complete study AVX-301 are also eligible for screening. The clinical study AVX-302 is similar and studies the efficacy and safety of a single dose of ATC (determined in AVX-301). Patients in AVX-302 who experience virologic failure or lack of virologic response will similarly be eligible for screening for entry into this study. In addition, patients who complete study AVX-302 are also eligible for screening. This is a phase 3, open-label, multi-center study of up to 96 weeks duration. Patients will receive for up to 96 weeks open-label ATC, initially at a dose of 1200mg orally BID. Following selection of the optimum ATC dose in protocol AVX-301 and termination of one of the two ATC doses (800mg or 1200mg orally BID) in protocol AVX-301, patients in this protocol will be transferred to the optimum dose, if required. The total number of patients expected to be enrolled in studies AVX-301 and AVX-302 is approximately 1866 in total.Patients will receive ATC orally in combination with their existing ART. Background antiretroviral therapy (ART) may be revised at any time during the study at the discretion of the investigator but must not include lamivudine, emtricitabine, zalcitabine or any other deoxycytidine analogue NRTI. The study will examine the safety and tolerability of long term treatment with apricitabine in combination with other ART.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing apricitabine in people with HIV Infections, run by Avexa.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 23 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The number, type and severity of SAEs occuring during the study (time frame: Week 96). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jun 2011.
