History of Changes
HIV replication can be effectively suppressed and acquired immunodeficiency syndrome(AIDS) can be prevented with highly active antiretroviral therapy (HAART). However, HIV-infected people must remain on treatment continuously to avoid viral rebound and progression to AIDS. HIV persistence is thought to stem primarily from the presence of integrated copies of the proviral genome within long-lived cells. Because active viral gene expression causes cell death due to viral cytopathic effects and the immune response, long-lived cells likely harbor transcriptionally silent, latent provirus. HIV-1 persistence in long-lived cellular reservoirs remains a major barrier to a cure. HDACi have the potential to activate ("Kick") these latently infected cells. This will make the HIV infected cells visible to the immune system; the immune response and antiretrovirals(ARVs) will be able to attack and eliminate ("Kill") the infected cells. This study is subsequent to our NCT02513901. The purpose of this study is to verify the efficacy of multi-dose Chidamide in combination with antiretroviral therapy in HIV-infected adults with suppressed viral load in a randomized controlled clinical trial.

Primary Outcome Measures
- Change in HIV transcription measured as cell associated HIV-1 RNA (copies per 10E6 PBMCs) [ Time Frame: Measured on week 0, 2, 4, 8, 12, 14, 16, 24 ]
- Change in HIV production measured as plasma HIV RNA (by Roche COMBAS TaqMan HIV-1 Test version 2.0) [ Time Frame: Measured on week 0, 2, 4, 8, 12, 14, 16, 24, 36, 48, 60, 72, 84, 96 ]
- Change in HIV-1 reservoir size measured in PBMCs by Total HIV-1 DNA(copies per 10E6 PBMCs) [ Time Frame: Measured on week 0, 2, 4, 8, 12, 14, 16, 24, 36, 48, 60, 72, 84, 96 ]
- Safety and tolerability evaluation as measured by adverse events (AE), adverse reactions (AR), serious adverse events (SAE), serious adverse reactions (SAR), serious unexpected adverse reactions (SUSAR) [ Time Frame: Measured through 96 weeks ]
- Cell surface markers of immune activation and immune checkpoints and so on [ Time Frame: Measured on week 0, 2, 4, 8, 12, 14, 16, 24, 36, 48, 60, 72, 84, 96 ]
- Plasma inflammatory biomarkers [ Time Frame: Measured on week 0, 4, 8, 12, 16, 24, 48, 72, 96 ]

|Estimated Study Completion Date:||December 2018|
|Estimated Primary Completion Date:||August 2018 (Final data collection date for primary outcome measure)|
Chidamide will be administrated 10mg each time, twice a week, interval not less than 3 days for 12 weeks.
ART plus Chidamide
Chidamide will be administrated 10mg each time, twice a week, interval not less than 3 days for 12 weeks.Antiretroviral therapy will be kept during entire study.
Placebo with the same taste and appearance like Chidamide will be administrated 10mg each time, twice a week, interval not less than 3 days for 12 weeks.
ART plus Placebo
Placebo will be administrated 10mg each time, twice a week, interval not less than 3 days for 12 weeks.Antiretroviral therapy will be kept during entire study.
Sixty participants will be recruited and stratified by their CD4 cell count(30 for <500
cells/μL and 30 for ≥500 cells/μL). Each layer was 1:1 randomly divided into Chidamide group
or Placebo-controlled group.Chidamide and Placebo will be administrated 10mg each time, twice
a week, interval not less than 3 days. Chidamide and Placebo intervention will last 12
consecutive weeks. All participants will keep their antiretroviral therapy during this study.
This study will last for 96 weeks, involving 16 study visits(Screening, Week 0, 2, 4, 8, 12, 14, 16, 20, 24, 36, 48, 60, 72, 84, 96) for every participant. At the screening visit, participants will give a medical history and will undergo a physical exam; blood samples will be collected. If participants agree, their blood samples may be stored for future research.
