Evaluation of the Safety and the Tolerability of a Combination of Two HIV Inducers in Patients With Undetectable Viral Load

A Pilot Open Label Phase I Trial to Evaluate the Safety and the Tolerability of a Combination of Two HIV-1 Inducers in HIV+ Sub-type B Patients Under cART With Undetectable Viral Load

Source: ClinicalTrials.gov · Last updated 11 Jun 2026

Brief summary (registry, in English)

The ANRS 171 SYNACTHIV trial is a monocenter pilot open label phase I trial. This trial will evaluate new procedures in LRA administration in 3 successive cohorts. In case of grade 3 to grade 5 adverse events, the inclusions and treatments will be (but not in a definitive manner) discontinued until the DSMB will conclude that the event was unrelated. Enrolment in cohort 2 then in cohort 3 will start only if no clinical grade 3 to grade 5 adverse event related to the LRAs occurs in the previous cohort.

  • Man who want to father a child or refuse contraception (condoms) while receiving treatment and for 3 months following completion of treatment; Man with a female partner of childbearing potential who refuses to use a highly effective contraceptive method during the same period (Experimental treatment period and for 3 months following completion of experimental treatment).
  • Treated with CYP 450 inducer or inhibitor, in particular dexamethasone, carbamazepine, phenytoin, rifabutin, rifapentine and phenobarbital;
  • Treated with warfarin or coumarin derivative;
  • Received any vaccination within 4 weeks prior to the first administration of the study products and plan to receive throughout the study (with the exception of influenza and COVID-19 vaccines which can be injected 4 weeks after the last administration of the study products as well as the Monkeypox vaccination that will be allowed during trial if participant becomes a contact at risk for monkeypox infection (according to national recommendations));
  • Treated with sexual hormone during the administration period of the study treatments (until CXD32);
  • Any significant acute medical illness in the 8 weeks prior to pre-screening and until inclusion;

Other illness

  • History of an AIDS-defining clinical illness (based on CDC classification);
  • Active coinfection with viral hepatitis B;
  • Active coinfection with viral hepatitis C;
  • Active malignancy that may require chemotherapy or radiation therapy;
  • Liver insufficiency (Child Pugh score \>5);
  • Kidney insufficiency (Estimation of glomerular filtration\<60mL/mn/1,73m2 ; evaluation with CKDepi formula, according to the 2012 French Haute autorité de santé recommandations);

Lab values

  • Clinically significant cardiac disease including QTc-prolongation (QTc value \> 450msec);
  • Treated with anti-arrhythmic medicines or medicinal products that lead to significant QT prolongation;
  • Haematological or biochemical laboratory parameters at pre-screening and screening : Hemoglobin (\<LLN), absolute neutrophil count (\<LLN), platelets (\<LLN), INR (\>1.2), Partial Thromboplastin Time (\>ULN); grade ≥ 2 for the following parameters: Total serum Creatinine, urea, uric acid, glycemia, total serum bilirubin, Alkaline Phosphatase (ALP) AST-ALT, gammaglutamyl transferase (GGT), lipasemia, LDH, Ionogram: Na, K, Ca, Mg, CRP, albumin, proteins, CPK;

Other

  • On PI based regimen or regimen containing NNRTI (except Doravirine which is allowed), Ritonavir or Cobicistat;
  • Participant under guardianship or curatorship or deprived of their liberty by a judicial or administrative decision
  • Participant potentially inable to follow the protocol requirements (e.g. comprehension of the study requirements, ability to understand and comply with procedures for collection of safety data, expressed availability for the required study period, and ability and willingness to attend scheduled visits).

  • HIV plasma viral load persistently \< the threshold (of the local test used) and undetectable during the 12 months prior to pre-screening and until inclusion;
  • CD4+ T-cells count nadir ≥ 200 cells per mm3 documented in the medical file; Transient CD4+ T-cells count \< 200 cells per mm3 is allowed for a short period if the value is associated with a single isolated acute infection
  • CD4+ T-cells count ≥ 500 cells per mm3 for at least 12 months before pre-screening and until inclusion;
  • EBV viral load \< 1000 cp.mL-1, CMV viral load \< 10000 cp mL-1;
