Clinical Trial Summary

ING111762 is a 48 week, randomized, double-blind, active-controlled, multicenter, parallel group, non-inferiority study. The study will be conducted in at least 688 HIV-1 infected antiretroviral experienced, integrase-naïve subjects. Subjects will be randomized 1:1 to receive GSK1349572 50 mg once daily or raltegravir (RAL) 400 mg twice daily, each added to an investigator selected background regimen consisting of at least one fully active agent plus no more than one second single agent which may or may not be active. Antiviral activity, safety, pharmacokinetics (PK), and development of viral resistance will be evaluated.

Description:

ING111762 is a 48 week, randomized, double-blind, active-controlled, multicenter, parallel group, non-inferiority study. The study will be conducted in at least 688 HIV-1 infected antiretroviral experienced, integrase-naïve subjects. Subjects will be randomized 1:1 to receive GSK1349572 50 mg once daily or raltegravir (RAL) 400 mg twice daily, each added to an investigator selected background regimen consisting of at least one fully active agent plus no more than one second single agent which may or may not be active. Antiviral activity, safety, pharmacokinetics (PK), and development of viral resistance will be evaluated.

Subjects must have documented genotypic or phenotypic resistance to at least one member of each of at least two antiretroviral therapy (ART) drug classes [nucleoside/nucleotide reverse transcriptase inhibitor (N[t]RTI), non-nucleoside reverse transcriptase inhibitor (NNRTI), protease inhibitor (PI), fusion inhibitor (T20), or entry inhibitor (chemokine receptor 5 [CCR5] antagonist)].

The primary analysis will take place after the last subject completes 48 weeks on therapy. An additional data cut and analysis will be conducted after the last subject completes 24 weeks on therapy.

Subjects randomized to GSK1349572 who successfully complete Week 48 will continue to received GSK1349572 until either it is locally available, until they no longer derive clinical benefit, until they meet a protocol-defined reason for discontinuation, or until development of the compound is terminated.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Absolute Values of Cluster of Differentiation 8+ (CD8+) Cell Counts at Weeks 4, 8, 12, 16, 24, 32, 40, and 48	The absolute value data for CD8+ cell count was planned to be evaluated. The results for this outcome measure will never be posted.	At Weeks 4, 8, 12, 16, 24, 32, 40, and 48
Other	Change From Baseline in CD8+ Cell Counts at Weeks 4, 8, 12, 16, 24, 32, 40, and 48	Change from Baseline data for CD8+ cell count was planned to be evaluated. The results for this outcome measure will never be posted.	Baseline (Day 1); Weeks 4, 8, 12, 16, 24, 32, 40, and 48
Primary	Percentage of Participants With HIV-1 Ribonucleic Acid (RNA) <50 Copies/Milliliter (c/mL) at Week 48	The percentage of participants with Plasma Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) <50 c/mL at Week 48 was assessed using the Missing, Switch or Discontinuation = Failure (MSDF), as codified by the Food and Drug Administration (FDA) "snapshot" algorithm. This algorithm treated all participants without HIV-1 RNA at Week 48 as nonresponders, as well as participants who switched their concomitant ART prior to Week 48 as follows: background ART substitutions non-permitted per protocol (one background ART substitution was permitted for safety or tolerability); background ART substitutions permitted per protocol unless the decision to switch was documented as being before or at the first on-treatment visit where HIV-1 RNA was assessed. Otherwise, virologic success or failure was determined by the last available HIV-1 RNA assessment while the participant was on-treatment in the randomized phase of the study.	At Week 48
Secondary	Number of Participants (Par.) With Detectable Virus That Has Genotypic or Phenotypic Evidence of Treatment-emergent Integrase Inhibitor (INI) Resistance at Time of Protocol Defined Virology Failure (PDVF)	For par. meeting one of the criteria for PDVF, plasma samples collected at the time point of virologic failure and Baseline were tested to evaluate any potential genotypic and/or phenotypic evolution of resistance. PDVF was defined as (A) virologic non-response: a decrease in plasma HIV-1 RNA of <1 logarithm to base 10 (log10) copies/mL by Week 16, with subsequent confirmation, unless plasma HIV-1 RNA is <400 copies/ mL; confirmed plasma HIV-1 RNA levels >=400 copies/mL on or after Week 24 or (B) virologic rebound: confirmed rebound in plasma HIV-1 RNA levels to >=400 copies/mL after prior confirmed suppression to <400 copies/mL; confirmed plasma HIV-1 RNA levels >1 log10 copies/mL above the nadir value, where nadir is >=400 copies/mL.Treatment-emergent IN mutations are those detected at the time of PDVF but not at Baseline.	Baseline (Day 1) until PDVF (Up to Week 48)
Secondary	Number of Participants With Plasma HIV-1 RNA <50 c/mL at Week 24	The number of participants with Plasma Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) <50 c/mL at Week 24 was assessed using the Missing, Switch or Discontinuation = Failure (MSDF), as codified by the Food and Drug Administration (FDA) "snapshot" algorithm. This algorithm treated all participants without HIV-1 RNA at Week 24 as nonresponders, as well as participants who switched their concomitant ART prior to Week 24 as follows: background ART substitutions non-permitted per protocol (one background ART substitution was permitted for safety or tolerability); background ART substitutions permitted per protocol unless the decision to switch was documented as being before or at the first on-treatment visit where HIV-1 RNA was assessed. Otherwise, virologic success or failure was determined by the last available HIV-1 RNA measurement through Week 24 (within window) while the participant was on-treatment. The result below corresponds to the Week 24 interim analysis.	At Week 24
Secondary	Number of Participants With Plasma HIV-1 RNA <400 c/mL at Week 24 and Week 48	The number of participants with Plasma Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) <400 c/mL at the visit of interest was assessed using the Missing, Switch or Discontinuation = Failure (MSDF), as codified by the Food and Drug Administration (FDA) "snapshot" algorithm. This algorithm treated all participants without HIV-1 RNA at the visit of interest as nonresponders, as well as participants who switched their concomitant ART prior to the visit of interest as follows: background ART substitutions non-permitted per protocol (one background ART substitution was permitted for safety or tolerability); background ART substitutions permitted per protocol unless the decision to switch was documented as being before or at the first on-treatment visit where HIV-1 RNA was assessed. Otherwise, virologic success or failure was determined by the last available HIV-1 RNA measurment (within window) for the timepoint of interest while the participant was on-treatment.	At Week 24 and Week 48
Secondary	Absolute Values of Cluster of Differentiation 4+ (CD4+) Cell Counts at Baseline (Day 1) and Weeks 4, 8, 12, 16, 24, 32, 40, 48, 96 and 144	Blood samples were collected at specified time points to assess CD4+ using flow cytometry. Median and interquartile range are presented. Baseline was the latest pre-dose assessment value (Day 1).	Baseline (Day 1) and Weeks 4, 8, 12, 16, 24, 32, 40, 48, 96 and 144
Secondary	Change From Baseline in CD4+ Cell Counts at Weeks 4, 8, 12,16, 24, 32, 40, 48, 96 and 144	Blood samples were collected at specified time points to assess CD4+. It was evaluated by flow cytometry. Baseline was the latest pre-dose assessment value (Day 1). Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Median and interquartile range is presented.	Baseline (Day 1) and Weeks 4, 8, 12, 16, 24, 32, 40, 48, 96 and 144
Secondary	Number of Participants With Post-Baseline HIV-associated Conditions, Excluding Recurrences, and Disease Progressions	Clinical disease progression (CDP) was assessed according to the Centers for Disease Control and Prevention (CDC) HIV-1 classification system. Category (CAT) A: one or more of following conditions (CON), without any CON listed in Categories B and C: Asymptomatic HIV infection, persistent generalized lymphadenopathy, acute (primary) HIV infection with accompanying illness or history of acute HIV infection. CAT B: Symptomatic CON that are attributed to HIV infection or are indicative of a defect in cell-mediated immunity; or that are considered by physicians to have clinical course or to require management that is complicated by HIV infection; and not included among CON listed in clinical CAT C. CAT C:Clinical CON listed in acquired immunodeficiency syndrome (AIDS) surveillance case definition. Indicators of CDP defined as:CDC CAT A at Baseline (BS) to CDC CAT C event (EV); CDC CAT B at BS to CDC CAT C EV; CDC CAT C at BS to new CDC CAT C EV; or CDC CAT A, B, or C at BS to death.

Any abnormality in clinical chemistry and hematology parameters were evaluated according to the DAIDS toxicity scale From Grade 1 to 4: Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe) and Grade 4 (Potentially life-threatening).Higher the grade, more severe the symptoms.	From Week 48 to Week 480
Secondary	DTG PK Parameters Including Maximum Plasma Drug Concentration (Cmax), Minimal Plasma Drug Concentration (Cmin), and Average Plasma Pre-dose Concentration (C0_avg)	Cmax, Cmin and C0_avg were assessed by population pharmacokinetic (PK) modeling using sparse PK samples which were collected as follows: one pre-dose sample and one post-dose sample at 1 to 3 hours/4 to 12 hours at Week 4, one pre-dose sample at Week 24, and one pre-dose sample and one post-dose sample at 1 to 3 hours/4 to 12 hours at Week 48. Cmax, Cmin and C0_avg were estimated and reported here.	Pre-dose and at 1 to 3 hours or 4 to 12 hours post-dose at Week 4; Pre-dose at Week 24; Pre-dose and 1 to 3 hours or 4 to 12 hours post-dose at Week 48
Secondary	DTG PK Parameter Including Pre-dose Concentration (C0)	C0 was assessed by population PK modeling using sparse PK samples which were collected as follows: one pre-dose sample and one post-dose sample at 1 to 3 hours/4 to 12 hours at Week 4, one pre-dose sample at Week 24, and one pre-dose sample and one post-dose sample at 1 to 3 hours/4 to 12 hours at Week 48. DTG predose concentration (C0) at Week 4, Week 24, and Week 48 was estimated and reported here.	Pre-dose at Weeks 4, 24 and 48
Secondary	DTG PK Parameters Including Area Under the Plasma Concentration-time Curve From Time Zero to Time Tau Over a Dosing Interval at Steady State (AUC[0-tau])	AUC is defined as the area under the DTG concentration-time curve as a measure of drug exposure over time. AUC(0-tau) is defined as the area under the plasma concentration-time curve from time zero to time tau over a dosing interval at steady state, where tau is the length of the dosing interval of DTG. AUC was assessed by population pharmacokinetic (PK) modeling using sparse PK samples which were collected as follows: one pre-dose sample and one post-dose sample at 1 to 3 hours/4 to 12 hours at Week 4, one pre-dose sample at Week 24, and one pre-dose sample and one post-dose sample at 1 to 3 hours/4 to 12 hours at Week 48.	Pre-dose and at 1 to 3 hours or 4 to 12 hours post-dose at Week 4; Pre-dose at Week 24; Pre-dose and 1 to 3 hours or 4 to 12 hours post-dose at Week 48
Secondary	Change From Baseline in European Quality of Life-5 Dimensions-3 Levels (EQ-5D-3L) Utility Score	The EQ-5D-3L questionnaire provides a profile of participant function and a global health state rating. The five-item measure has one question assessing each of five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression and 3 levels for each dimension including 1=no problems, 2=some problems, 3=extreme problems. The health state is defined by combining the levels of answers from each of the 5 questions. Each health state is referred to in terms of a 5 digit code. Health state 5 digit code is translated into utility score, which is valued up to 1 (perfect health) with lower values meaning worse state. EQ-5D-3L utility score ranges from -0.594 to 1. Higher scores indicate better health. Baseline was the latest pre-dose assessment value (Day 1) and change from Baseline=post-dose value minus Baseline value.	Baseline (Day 1) and at Weeks 24 and 48
