E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective is to evaluate virologic safety, e.g. maintenance of virologic suppression, after 12 weeks of switch from NVP + ABC/3TC to DTG/ABC/3TC. |
|
E.2.2 | Secondary objectives of the trial |
- to evaluate pharmacokinetic of NVP and DTG after swtiching from NVP to DTG. The objective is to assess residual concentrations of NVP over 2 weeks following NVP cessation and Cmin of DTG over the first 12 weeks following NVP-DTG switch to determine the extent of potential inducing effect of NVP on DTG.
- to assess DTG PK with and without concomitant NVP administration
- to assess maintenance of virologic suppression through 48 weeks
- to evaluate safety and tolerability
- to evaluate treatment satisfaction |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacokinetics evaluation.
To further address potential drug-drug interaction, a subgroup of 10 patients (Group 2) will have an overlap of 5 days, receiving both NVP-XR and ABC/3TC/DTG, before stopping NVP-XR and continuing solely ABC/3TC/DTG. A 24h pharmacokinetics evaluation of both NVP and DTG will be performed in these 10 patients at Day 0 (at steady-state, 5 days after concomitant intake of NVP-XR + ABC/3TC/DTG) and of DTG at Week 2 (14 days after NVP discontinuation). |

• HLA-B*5701 negative test
• Subjects covered by Health Insurance |
|
E.4 | Principal exclusion criteria |
• Woman of child-bearing potential without effective contraception method.
For contraception during the trial all women must use a combination of mechanical method and a second method other than an oral contraceptive. Oral contraceptives are not to be used during the trial. Pregnant or breastfeeding woman.
• Woman expecting to conceive during the study period
• HIV-2 co-infection
• Any prior exposure to integrase inhibitor(s)
• plasma HIV-1 RNA > 50 c/mL in the past year
• Creatinine clearance < 60 ml/mn (estimated glomerular filtration rate according to the MDRD equation),
• Alkaline phosphatase, ASAT or ALAT ≥ 5 times the upper limit of the norm (ULN)
• Patient with history of decompensated liver disease
• Any major IAS-USA mutation conferring resistance to one or more of reverse transcriptase or integrase inhibitors on genotypic testing at screening (DNA genotype) or on any historical plasma genotype if available. Any previous genotype result is valid, with no time limit, as long as the original test result is documented.
• Mycobacteriosis under treatment
• Malignancy requiring chemotherapy or radiotherapy
• Positive HBs Ag
• HCV infection for which specific treatment is ongoing or planned during the study
• Known hypersensitivity to one of the trial drugs, the metabolites or formulation excipients
• Concomitant therapy with antacids or H2 antagonists
• Contraindicated concomitant treatment
• Anticipated non-compliance with the protocol
• Participation in another clinical trial with an on-going exclusion period at screening
• Subject under legal guardianship or incapacitation
• Subject, who in the opinion of the investigator, is unable to complete the study period |
