A Pilot Study Assessing the Integrase Inhibitor GSK1349572 in HIV-infected Persons With Virus Resistant to Raltegravir

5 de novembro de 2015 atualizado por: ViiV Healthcare

A Pilot Study to Assess the Antiviral Activity of GSK1349572 Containing Regimen in Antiretroviral Therapy (ART)-Experienced, HIV-1-infected Adult Subjects With Raltegravir Resistance

Integrase is an enzyme produced by HIV so that the virus can multiply in the human body. GSK1349572 is a new drug in the integrase inhibitor class that prevents the enzyme from working properly and therefore prevents the virus from multiplying.

GSK1349572 has shown to be effective against viruses in a short-term monotherapy study in adults with no previous exposure to integrase inhibitors. The purpose of this study is to determine whether GSK1349572 is effective in the treatment of HIV-infected patients who no longer respond to treatment with the approved integrase inhibitor raltegravir and carry viruses with resistance to this drug. The safety and efficacy of GSK1349572 50mg once daily in combination with the background HIV drugs previously administered (unless discontinuation of a particular drug is required) will be assessed over 10 days (functional monotherapy phase), followed by the evaluation of the safety and efficacy of GSK1349572 given with a new optimised background regimen from Day 11 through at least Week 24.

Descrição detalhada

Study (ING112961) is a Phase IIb, multicentre, open-label, single arm, two cohorts, pilot study to assess the antiviral activity of GSK1349572 containing regimen in HIV-1 infected ART-experienced adults with raltegravir (RAL) resistance. The study will include approximately 50 ART-experienced subjects with either current or past virologic failure to RAL. All subjects must harbour isolates with RAL resistance mutations at Screening. Subjects should also have documented genotypic and/or phenotypic resistance to at least one compound from each of three or more of the approved classes of ART (including integrase inhibitors [INIs]). Subjects with current RAL virologic failure will substitute RAL with GSK1349572 50mg once daily and continue the remaining components of their failing regimen through Day 10. Subjects with historical RAL virologic failure will add GSK1349572 50mg once daily to their failing regimen through Day 10. On Day 11 all subjects will continue GSK1349572 and optimize their background therapy. Antiviral activity, safety and tolerability of GSK1349572 will be evaluated at Day 11 and over time through at least Week 24.

ViiV Healthcare is the new sponsor of this study, and GlaxoSmithKline is in the process of updating systems to reflect the change in sponsorship.

The CDC classifies HIV infection as Category A (participants with asymptomatic HIV infection, acute HIV infection with accompanying illness, or persistent generalized lymphadenopathy), Category B (participants with symptomatic non-AIDS condition, i.e., conditions that are attributed to HIV infection or are indicative of a defect in cell-mediated immunity; or conditions are considered by physicians to have a clinical course or to require management that is complicated by HIV infection), and Category C (includes AIDS indicator conditions as defined by diagnostic or presumptive measures).

PDVF is defined in relation to Baseline plasma HIV-1 RNA levels: at Day 11, a decrease of <0.7 log10 c/mL unless <400 c/mL; at Weeks 8 to <16, a decrease of <1.0 log10 c/mL unless <400 c/mL or an increase of >= 1.0 log10 c/mL from nadir; and at or after Week 16, ≥400 c/mL. PDVF at Day 11 was based on a single plasma HIV-1 RNA evaluation and did not require confirmation. Confirmation testing was required for visits at or after Week 8. For the combination treatment phase, all HIV-1 RNA samples that meet a criterion for suspected PDVF must be confirmed by a second measurement performed at least 1 week but not more than 4 weeks apart from the date of the original sample.

Prazo: Baseline
At Baseline, the integrase genotypic results were used to document resistance to raltegravir (RAL) and for the allocation of participants to one of two genotypic groups according to their RAL signature mutations to ensure a broad range of sensitivity to DTG. These results were not used to pre-define subgroup for analysis.
Baseline
Median Fold Change in Sensitivity to DTG by the Baseline (Day 1) IN Mutational Group
Prazo: Baseline (Day 1)
Summary of median fold change in sensitivity to DTG by Integrase (IN) mutational group was assessed.

An analysis of changes at specific amino acids in the IN coding region associated with resistance to raltegravir, elvitegravir, or DTG was performed at Day 1 and at the time of PDVF. PDVF is defined in relation to Baseline plasma HIV-1 RNA levels: at Day 11, a decrease of <0.7 log10 c/mL unless <400 c/mL; at Weeks 8 to <16, a decrease of <1.0 log10 c/mL unless <400 c/mL or an increase of >= 1.0 log10 c/mL from nadir; and at or after Week 16, ≥400 c/mL. PDVF at Day 11 was based on a single plasma HIV-1 RNA evaluation and did not require confirmation. Confirmation testing was required for visits at or after Week 8. For the combination treatment phase, all HIV-1 RNA samples that meet a criterion for suspected PDVF must be confirmed by a second measurement performed at least 1 week but not more than 4 weeks apart from the date of the original sample.

Prazo: From Baseline (Day 1) until study completion (median 605 days for Cohort I, median 1181 days for Cohort II)
The FC in IC50 (50% inhibitory concentration) for DTG relative to wild-type virus was determined for virus isolated at Baseline and at the time of PDVF.The number of participants with the indicated change (ratio) in the two values at the time of PDVF is presented. PDVF is defined in relation to Baseline plasma HIV-1 RNA levels: at Day 11, a decrease of <0.7 log 10 c/mL unless <400 c/mL; at Weeks 8 to <16, a decrease of <1.0 log 10 c/mL unless <400 c/mL or an increase of >=1.0 log 10 c/mL from nadir; and at or after Week 16, ≥400 c/mL . PDVF at Day 11 was based on a single plasma HIV-1 RNA evaluation and did not require confirmation. Confirmation testing was required for visits at or after Week 8.
