Clinical Utility Of Genetic Screening For HLA-B*5701, On Susceptibility To Abacavir Hypersensitivity

Phase 4

Completed

• Conditions: HIV Infection

• Registration Number: NCT00340080
• Lead Sponsor: GlaxoSmithKline

Brief Summary

Study to evaluate the utility of prospective HLA-B\*5701 screening on the incidence of abacavir hypersensitivity (ABC HSR) in 1800 previously ABC-naive adults with HIV-1 from Europe, Australia and other countries as applicable. The study has two (co-primary) objectives: i) to determine if screening for HLA-B\*5701 prior to ABC-containing HAART results in a lower incidence of clinically-suspected HSR versus current standard of care (no genetic screening) and ii) to determine if screening for HLA-B\*5701 prior to ABC-containing HAART, results in a significantly lower incidence of immunologically-confirmed HSR versus current standard of care (no genetic screening or patch testing). The study consists of up to a 28-day screening period, a randomised observation period (Day 1 through Week 6) and, for subjects experiencing a suspected ABC HSR and a subset of ABC-tolerant subjects, an epicutaneous patch test (EPT) assessment period. Eligible subjects will be randomised to one of two study arms: a Current Standard of Care Arm (no prospective genetic screening: Control) and a Genetic Screening Arm (prospective genetic screening). Subjects identified as HLA-B\*5701 positive in the prospective Genetic Screening Arm will not receive ABC and will be excluded from further study. Subjects who experience suspected ABC HSR during the 6-week observation will be withdrawn from ABC-containing product and undergo EPT patch testing 6 weeks later.
