NCT03160105

Brief Summary

The purpose of this study is to evaluate whether maintenance antiretroviral therapy could be simplified to DTG + FTC dual therapy and/or patient-centered monitoring once virological suppression is achieved. Using a factorial design, the study aims to assess the efficacy of DTG + FTC dual therapy to maintain virological suppression through 48 weeks of follow-up as well as the costs of a patient-centered ART laboratory monitoring.

Study Arms (4)

Continuing cART + Standard monitoring

NO INTERVENTION

Patients randomized to this arm will continue their current standard ART regimen (cART) and will continue a standard 3-monthly routine safety biological monitoring (including CD4 cell count, fasting lipids and glucose, renal and hepatic function tests) at their SHCS site.

Continuing cART + Patient-centered monitoring

EXPERIMENTAL

Patients randomized to this arm will continue their current cART and will have immunological and safety blood examinations performed once per year and at least one options (decentralised venipuncture and blood tests, delivery of ARV drugs by mail and interview by phone or skype call) for weeks 6, 12 and 36

Other: Patient-centered monitoring

Switch to DTG+FTC + Standard monitoring

EXPERIMENTAL

Patients randomized to this arm will be switched to DTG + FTC dual maintenance therapy and will have immunological and safety blood examinations performed once per year and at least one options (decentralised venipuncture and blood tests, delivery of ARV drugs by mail and interview by phone or skype call) for weeks 6, 12 and 36

Drug: Switch to DTG + FTC

Switch to DTG+FTC + Patient-centered monitoring

EXPERIMENTAL

Patients randomized to this arm will be switched to DTG + FTC dual maintenance therapy and will have immunological and safety blood examinations performed at screening and at week 48. In addition, patients will be ask to choose at least one of the following alternative options for weeks 6, 12 and 36: decentralised venipuncture and blood tests, delivery of ARV drugs by mail and Assessment and clinical interview by phone or skype call

Drug: Switch to DTG + FTCOther: Patient-centered monitoring

Interventions

Switch from standard cART to DTG + FTC dual maintenance therapy.

Switch to DTG+FTC + Patient-centered monitoringSwitch to DTG+FTC + Standard monitoring

Immunological and safety blood examinations performed only once per year at least one options (decentralised venipuncture and blood tests, delivery of ARV drugs by mail and interview by phone or skype call) for weeks 6, 12 and 36

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Informed consent as documented by signature;
  • Documented HIV-1 infection;
  • Enrolled in the Swiss HIV Cohorte Study (SHCS) or receiving care from a medical doctor of the SHCS network;
  • ≥ 18 years of age;
  • HIV-RNA \<50 copies/mL at screening and for at least 24 weeks before screening on effective suppressive cART, one blip with less than 200 copies/mL being allowed during this period if followed by at least 2 results \< 50 copies/mL.
  • NRTIs + either 1 NNRTI, 1 boosted PI or 1 INSTI;
  • NRTI-sparing triple ARV regimen (e.g. 1 NRTI + 1 NNRTI + 1 InSTI);
  • Dual therapy with protease inhibitor.

You may not qualify if:

  • HIV-2 infection;
  • Previous ART change for unsatisfactory virological response, i.e. slow initial virological suppression, incomplete suppression or rebound. Change of drug or drug class for convenience or toxic effect prevention or management is allowed.
  • Note: patients with documented genotype(s) presenting only a M184V mutation remain eligible;
  • Creatinine clearance \< 50ml/min;
  • ASAT or ALAT \>2.5x upper limit of the norm;
  • Known hypersensitivity, intolerance or allergy to DTG or FTC;
  • Known or suspected non-adherence (defined as \<80% adherence, i.e. missed doses \> 1x/week) to current treatment in the last 6 months;
  • Concomitant use of drugs that decrease DTG blood concentrations including carbamazepine, oxcarbamazepine, phenytoin, phenobarbital, St John's wort and rifampicin;
  • Women who are pregnant or breast-feeding;
  • b. Non availability of previous routine resistance test, at least for reverse transcriptase and protease genes.
  • Note: Subjects remain eligible in the absence of any previous resistance test only if they are on their first-line antiretroviral regimen;
  • Evidence of acute or chronic hepatitis B virus infection based on results of serology testing.
