Study Overview
Brief Summary
The purpose of this study is to assess the ability of the early initiation of cART or cART in combination with autologous HIV-1 specific cytotoxic T lymphocyte (CTL) infusion to achieve a post-treatment control among treatment-naïve acute HIV-infected adults.
Detailed Description
Although combined antiretroviral therapy (cART) can suppress HIV-1 replication to a very low level in the blood, but it cannot eliminate latent viral reservoirs, and need lifelong adherence to expensive regimens that have potential side effects. Increasing evidence indicates that early antiretroviral therapy for recently HIV-infected patients results in slower progression of HIV disease and represent a unique opportunity to interfere with either the quantities or qualities of persistent reservoirs of replication-competent virus. However, the time course before the interruption of cART is unclear. This study will compare the virological and immunological outcomes and HIV latency of recently infected adults who receive cART or cART in combination with autologous HIV-1 CTL infusion for different periods.
The study will last 120 weeks. Participants will be randomly assigned to either the cART or the cART plus autologous HIV-1 CTL infusion arm of one of three cohorts. The three cohorts will differ in the period of cART given. Cohort 1, Cohort 2 or Cohort 3 will receive cART (Zidovudine (AZT)/Tenofovir disoproxil fumarate (TDF) +Lamivudine (3TC） + Lopinavir / Ritonavir （LPV/r)） for 48, 72 or 96 weeks, respectively. After 48, 72 or 96 weeks, cART will be interrupted respectively. Study visits will occur at study entry, Week 4 and 12, and every 12 weeks thereafter through treatment interruption, then every 4 weeks through 12 weeks later, then every 12 weeks through Week 120. At each study visit, a physical exam, blood collection, and completion of an adherence questionnaire will occur. Clinical, virological, and immunological evaluations and HIV latency examination will be performed at most study visit.

Outcomes
Primary Outcomes
Change from baseline in HIV DNA quantification at the interruption of cART
Time Frame: 48 weeks for Cohort 1, 72 weeks for Cohort 2, 96 weeks for Cohort 3
HIV DNA detection includes total HIV DNA, integrated HIV DNA , 2-long terminal repeat （LTR） HIV DNA in resting CD4+T cell subsets.
Number of patients who achieve virological remission
Time Frame: 72 weeks for Cohort 1, 96 weeks for Cohort 2, 120 weeks for Cohort 3
Virological remission is defined as undetectable of plasma HIV RNA for 24 weeks after the interruption of cART.
Secondary Outcomes
- Number of patients who need to initiate late treatment(120 weeks)
- Time from cART interruption to virological relapse (plasma viral load more than 50 copies/mL)(120 weeks)
- Number of patients who occur any grade 3 or 4 (clinical or laboratory) adverse events(120 weeks)
- HIV-1 specific CD4+ and CD8+ T cell responses at week 120(120 weeks)
