A Study to Assess Dolutegravir in HIV-infected Subjects With Treatment Failure on an Integrase Inhibitor Containing Regimen. (VIKING-3)

2015年12月7日 更新者：ViiV Healthcare

A Phase III Study to Demonstrate the Antiviral Activity and Safety of Dolutegravir in HIV-1 Infected Adult Subjects With Treatment Failure on an Integrase Inhibitor Containing Regimen.

The purpose of this trial is to assess the antiviral activity and safety of a dolutegravir (DTG) containing regimen in HIV-1 infected, antiretroviral therapy (ART)-experienced adults with current or historical failure on an integrase inhibitor (INI) containing regimen. The study will assess DTG 50mg twice daily administered initially with the current failing ART regimen but then with an optimised background ART regimen (OBR) after Day 7. The first analyses will be conducted after the last subject enrolled has completed 24 weeks. Subjects may remain on study after Week 24.

詳細な説明

ING112574 is a Phase 3, multicentre, open-label, single arm study to assess the antiviral activity and safety of DTG containing regimen in HIV-1 infected ART-experienced adults with historical or current evidence of resistance to RAL or ELV. Initially, a minimum of 100 subjects will be enrolled to receive DTG 50mg twice daily with the current failing regimen for 7 days but with OBR from Day 8. Subjects must also have documented genotypic and/or phenotypic resistance to at least one compound in two or more of the other approved classes of ART but must also be able to include at least one fully active drug in the OBR to be started Day 8. The first data cut will take place after the (approximate) 100th subject enrolled completes the Week 24 visit. Enrollment will continue until a further 50 to 100 subjects have been recruited. All subjects who successfully complete 24 weeks of treatment will continue to have access to DTG until it is locally available as long as they continue to derive clinical benefit.

Mean Change From Baseline in Plasma HIV-1 RNA at Day 8
時間枠：Baseline and Day 8
Mean change from Baseline in Plasma Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) at Day 8 was calculated as the Day 8 value minus the Baseline value. The last observation was carried forward if a participant had missed the Day 8 visit. The Baseline observation was carried forward if a participant had discontinued the treatment before Day 8. Blood samples for assessment of HIV-1 RNA levels were collected at Baseline and Day 8.
Baseline and Day 8
Number of Participants With HIV-1 RNA Less Than 50 Copies/mL at Week 24
時間枠：Week 24
The number of participants who had viral load <50 copies/mL at Week 24 based on the Food and Drug Administration's Snapshot algorithm was assessed. This algorithm treats all participants without HIV-1 RNA data at the visit of interest (VOI [due to missing data/discontinuation of investigational product prior to the visit window]) as nonresponders, as well as participants who switched their concomitant antiretroviral (ART) prior to the VOI as follows: background ART substitutions not permitted per protocol; background ART substitutions permitted per protocol, however the decision to switch was not documented as being before or at the first on-treatment visit after switching to optimized background regimen (i.e., Week 4) where HIV-1 RNA was assessed. Otherwise, virologic success/failure was to be determined by the last available HIV-1 RNA assessment while the participant was on treatment within the VOI analysis window.
Week 24
Number of Participants With HIV-1 RNA Less Than 50 Copies/mL at Week 48
時間枠：Week 48
The number of participants who had viral load <50 copies/mL at Week 48 based on the Food and Drug Administration's Snapshot algorithm was assessed. This algorithm treats all participants without HIV-1 RNA data at the visit of interest (VOI [due to missing data/discontinuation of investigational product prior to the visit window]) as nonresponders, as well as participants who switched their concomitant antiretroviral (ART) prior to the VOI as follows: background ART substitutions not permitted per protocol; background ART substitutions permitted per protocol, however the decision to switch was not documented as being before or at the first on-treatment visit after switching to optimized background regimen (i.e., Week 4) where HIV-1 RNA was assessed. Otherwise, virologic success/failure was to be determined by the last available HIV-1 RNA assessment while the participant was on treatment within the VOI analysis window.
Week 48
Number of Participants With Any Adverse Event (AE) or Any Serious Adverse Event (SAE)
時間枠：From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury.
From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)
Number of Participants With Adverse Events of the Indicated Severity, Per the Division of Acquired Immune Deficiency Syndrome (DAIDS) Grading Scale
時間枠：From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury. AE/SAE severity was graded according to the DAIDS grading scale. The DAIDS displays events as Grades 1-4 based on this general guideline: Grade (G) 1, mild; G2, moderate; G3, severe; G4, potentially life threatening.
From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)

The maximum plasma concentration (Cmax) and the concentration at the end of a dosing interval (Ctau) of DTG were assessed by a population pharmacokinetic (PK) modeling approach using pooled DTG PK data from multiple studies. For this study, blood samples for pharmacokinetic assessments were collected pre-dose on Day 8 and at Weeks 4 and 24, at 1-3 hours post-dose on Day 8, and at 1-3 hours or 4-12 hours post-dose at Weeks 4 and 24.
Day 8, Week 4, and Week 24
AUC(0-tau) and AUC(0-24) of DTG
時間枠：Day 8, Week 4, and Week 24
The area under the time concentration curve over the dosing interval (AUC[0-tau]) and from 0 to 24 hours (AUC[0-24]) of DTG was assessed by a population PK modeling approach using pooled DTG PK data from multiple studies. For this study, blood samples for pharmacokinetic assessments were collected pre-dose on Day 8 and at Weeks 4 and 24, at 1-3 hours post-dose on Day 8, and at 1-3 hours or 4-12 hours post-dose at Weeks 4 and 24.
Day 8, Week 4, and Week 24
C0 Assessment of DTG
時間枠：Day 8, Week 4, and Week 24
The plasma DTG concentration immediately prior to dosing at steady state (C0) was assessed at Day 8, Week 4, and Week 24. Blood samples for pharmacokinetic assessments were collected pre-dose and 1-3 hours post-dose on Day 8 and at Week 4 and 4-12 hours post-dose at Week 24. Different participants may have been analyzed at different time points, so the overall number of participants analyzed reflects everyone in the Pharmacokinetic Parameter Population.
Day 8, Week 4, and Week 24
Number of Participants With the Indicated Treatment-emergent Integrase (IN) Mutations Detected at the Time of Protocol-defined Virologic Failure (PDVF) as a Measure of Genotypic Resistance
時間枠：From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)
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 a <0.5 log10 copies(c)/mL decrease in plasma HIV-1 RNA at Day 8 unless the absolute value is <400 c/mL. PDVF after Day 8 is defined as virological non-respones (decrease in plasma HIV-1 RNA of <1 log10 c/mL by Week 16, with subsequent confirmation, unless plasma HIV-1 RNA <400 c/mL and confirmed plasma HIV-1 RNA levels >=400 c/mL on or after Week 24) and virological rebound (confirmed rebound in plasma HIV-1 RNA levels to >=400 c/mL after prior confirmed suppression to <400 c/mL and confirmed plasma HIV-1 RNA levels >1 log10 c/mL above the nadir value [nadir: >=400 c/mL]).
From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)
Number of Participants With the Indicated Fold Increase in DTG FC (Fold Change in IC50 Relative to Wild-type Virus) Between Baseline and the Time of PDVF, as a Measure of Post-Baseline Phenotypic Resistance
時間枠：From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)
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 as a <0.5 log10 copies/mL decrease in plasma HIV-1 RNA at Day 8 unless the absolute value is <400 copies/mL. PDVF after Day 8 was defined for virological non-response (decrease in plasma HIV-1 RNA of less than 1 log10 copies/mL by Week 16, with subsequent confirmation, unless plasma HIV-1 RNA <400 copies/mL and confirmed plasma HIV-1 RNA levels >=400 copies/mL on or after Week 24) and virological rebound (confirmed rebound in plasma HIV-1 RNA levels to >=400 copies/mL after prior confirmed suppression to <400 copies/mL and confirmed plasma HIV-1 RNA levels >1 log10 copies/mL above the nadir value, where nadir is >=400 copies/mL).
From the day of the first dose of study drug until end of treatment visit for each participant, up to Week 180 (median of 758 days)
