IMPAACT P1093
Phase I/II, Multi-Center, Open-Label Pharmacokinetic,
Safety, Tolerability and Antiviral Activity of Dolutegravir
(GSK1349572), a Novel Integrase Inhibitor, in Combination
Regimens in HIV-1 Infected Infants, Children and
Adolescents
IMPAACT P1093
Introduction and Overview
• Rationale: Unmet ARV needs remain in pediatric populations, especially
those with extensive resistance, drug intolerance or toxicity. Results from
P1093 will support regulatory filing for dolutegravir (GSK1349572) use in
pediatrics
• Hypothesis: Dolutegravir (GSK1349572), a novel integrase inhibitor, will be
well tolerated with acceptable safety profile and ARV activity when used
with an optimized background regimen in HIV infected pediatric
populations
Primary Objectives
• To select a dolutegravir dose for chronic dosing in infants, children and
adolescents that achieves similar exposure to the dolutegravir adult dose
selected from the Phase IIb clinical trial in ART-naïve adult subjects
• To determine the short term and long term safety and tolerability of
dolutegravir in HIV-1 infected infants, children and adolescents at 24 and
48 weeks
• To evaluate the steady-state pharmacokinetics of dolutegravir in
combination with other antiretrovirals (OBT) in treatment-experienced
and naïve HIV-1 infected infants, children and adolescents and to
determine the dose of GSK1349572 that achieves a targeted AUC24
(primary PK endpoint) and C24h (secondary PK endpoint) in this population
Secondary Objectives
• To evaluate the antiviral activity of dolutegravir in combination with an
OBT by measuring virologic response in infants, children and adolescents
at weeks 24 and 48
• To evaluate the effect on immunologic response from baseline to weeks
24 and 48
• To assess changes in HIV-1 genotype and phenotype to dolutegravir and
other components of the OBT in subjects experiencing virologic failure
• To determine the extended long term ( ≥ 48 weeks) safety and tolerability
of dolutegravir in HIV-1 infected infants, children and adolescents
IMPAACT P1093
• DESIGN: Phase I/II, multi-center, open-label, non-comparative study
• SITES: International and US
• SAMPLE SIZE: Approximately 160 infants, children and adolescents to
provide 100 evaluable subjects
• POPULATION: HIV-1 infected children and adolescents ages ≥4 weeks to
<18 years of age
• TREATMENT DURATION: 48 weeks plus long term safety follow-up (with
drug provided) until available, no benefit, patient endpoint or
discontinuation of dolutegravir development
• Two stages per cohort
– Stage I: At least 10 subjects in each age cohort
– Stage II: Opens after dose/safety criteria met in Stage I;
12 subjects per cohort (except cohort IIB)

Dolutegravir: Key Characteristics
• Only once daily, unboosted INI
– Long plasma half life (~15 hours)
– Consistent pharmacokinetics
– Clear and predictable exposure-response relationship
• Favorable drug interaction profile
– Primarily metabolized via glucuronidation with minor CYP3A4 component
• Virology: High potency in a low mg,
– 10 day monotherapy: Decrease VL=2.5 log copies/ml; 7/10 with VL<50
– ≥88% undetectable at Week 48 (vs. 82% with EFV) in SPRING-1
– Limited cross resistance to RAL in vitro and in vivo (VIKING)

SPRING 1: Safety Summary
• Dolutegravir was well-tolerated across all doses studied.
• No significant dose-dependent trends in safety parameters.
• More cases of headache were reported across the DTG treatment groups
(13%) than in the EFV control (2%); nausea – DTG (15%), EFV (10%).
• Small, non-progressive increases in serum creatinine have been observed
across the dolutegravir doses in this study. In vitro data supports OCT2
inhibition; iohexol study in healthy subjects shows no effect on GFR or
renal plasma blood flow
• Urine protein changes noted on DTG – not time or dose-dependent,
resolve independently, confounded by other conditions
– Direct assessments in peds and ph3 studies

Drug-drug Interactions
• Dolutegravir can be given with most ART agents without dose
adjustment or contraindication
• Dolutegravir can be given without food restrictions
• Exceptions (due to significant reduction in dolutegravir exposure)
– Disallowed concurrent medications:
• Etravirine (without PI/r)
• Rilpivirine
– Concurrent medications with caution:
• GSK1349572 should be taken 2 hours before or 6 hours after antacid products
containing divalent cations (e.g., Tums, Maalox)
Please refer to Section 4.3 in the protocol for complete list of

• Site Level: Study physician listed on
the 1572/IoR (Investigator of
Record) Agreement is responsible
for the assessment of AEs
• Sponsor Level: DAIDS MOs provide
secondary review

Serious versus Severe
Seriousness is NOT the same as Severity
Seriousness
Severity
Based on outcome of the AE
and is a factor in determining
reportability (regulatory
definition)
Based on the intensity of the
AE and is not a factor in
determining reportability
(clinical descriptor)
Determined using the SAE
criteria
Determined using the DAIDS
grading table

Site Investigator Signature
• A site physician investigator or sub-investigator listed
on the 1572 or the IoR Agreement must:
– Review and verify the completed report for accuracy and
completeness and
– Sign the report
• This physician makes the site’s final assessment of the
relationship to study agent(s)
