Brief Summary:
This study will follow a group of healthy male participants for about 18 weeks to see the effect of taking Acitretin on their immune cells

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Acitretin Phase 1

Detailed Description:
Retinoids have been shown in in vitro and ex vivo models to have the ability to reverse latency reactivating the HIV reservoir and the potential for selective eradication of HIV-harbouring cells. We feel that acitretin shows significant potential as a potential adjuvant to current ART regimens, however, there is a lack of data to demonstrate that treatment with acitretin at normal are able to induce molecular and transcription changes consistent with the above activities. In order to provide a scientific basis for retinoid therapy in HIV infection, a Phase I trial of acitretin in human subjects is proposed.

Drug Information available for: Acitretin

Arm Intervention/treatment
Experimental: Acitretin treatment Drug: Acitretin
Acitretin will be provided to participants in the formulation Soriatane. Soriatane doses are oral tablets taken daily by the participant. Participants will then receive 35mg of oral acitretin (Soriatane) daily for 8 weeks during the intervention phase. Participants will be asked to return two months after completion of the acitretin course for clinical follow-up and additional phlebotomy for laboratory testing.

Primary Outcome Measures :
  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 [ Time Frame: up to 5 months ]
    Safety of Acitretin use in healthy volunteers will be assessed using safety labs and C-SSRS

Secondary Outcome Measures :
  1. Change in α4β7 expression on peripherally circulating CD4 T cells [ Time Frame: Serial phlebotomy measured over 5 months ]
    Absolute change in α4β7 expression on peripherally circulating CD4 T cells measured using flow cytometry

  2. Maximum Plasma Concentration [Cmax] [ Time Frame: Trough concentrations measured serially over 2 months of active treatment ]
    Serum concentrations measured by HPLC

  3. Change in RIG-1 expression, p300 expression, mTOR expression [ Time Frame: Serial phlebotomy measured over 5 months ]
    Absolute change in RIG-1 expression by qRTPCR, and change in p300 expression by western blot, change in mTOR expression by qRTPCR and mTOR total/phosphorylated by western blot

  4. Area Under the Curve [AUC]). [ Time Frame: Trough concentrations measured serially over 2 months of active treatment ]
    Serum concentrations measured by HPLC
