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

ANRS 171 SYNACTHIV

The ANRS 171 SYNACTHIV trial is an international multicenter 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.
