The purpose of this study is to examine the ability of AGS-004 to control HIV-1 replication and to determine if HIV-1 immunotherapy made with dendritic cells is safe and well tolerated, to determine if immunotherapy increases the body's immune response to HIV-1; and, to determine if after stopping anti-HIV drugs, immunotherapy can control the HIV-1 virus.

Study summary:

Although chronic ART raises cluster of differentiation CD 4+ T cell counts and improves immune function, the immune systems' ability to control HIV-1 replication is not improved. AGS-004 is an immunotherapeutic agent made from autologous DCs co electroporated with amplified in vitro transcribed (IVT) ribonucleic acid (RNA) encoding CD40L and with IVT RNA encoding three or four autologous HIV-1 antigens. The HIV-1 RNA is derived from the plasma sample taken immediately prior to the initiation of ART.


Inclusion Criteria: - 18 to 60 years of age - HIV-1 infection - Subjects must be on their first ART regimen for at least 3 months: 2 NRTIs together with an NNRTI and/or at least 1 PI (prior changes to ART regimen are allowed if due to tolerability, guideline change, or to simply dosing but not for viral control) - Durable viral suppression (below limit of detection) for at least 3 months prior ot Screening - CD4+ T cell count ≥ 450 cells/mm3 for at least 90 days immediately prior to Screening - Availability of ≥ 1.2 mL of continually frozen plasma (may have been thawed and refrozen only once) drawn no more than 90 days before starting ART and preferably within 30 days. - Pre-ART plasma HIV-1 RNA levels of ≥ 15,000 copies/mL at the time the plasma was archived before commencing ART - Pre-ART nadir CD4+ T cell count ≥ 200 cells/mm3 (cell count of < 200 cells/mm3 on one occasion is allowed if subsequent pre-ART CD4+ cell counts were > 200 cells/mm3 on at least two time points. - Laboratory values obtained at Screening and confirmed just prior to Baseline Day 1: - Creatinine ≤ 1.5 x upper limit of normal (ULN); - AST (SGOT), ALT (SG`PT), and alkaline phosphatase ≤ 3 x ULN; - ANC ≥ 750 cells/mm3; - Hemoglobin ≥ 10 g/dL; and, - Platelet count ≥ 75,000/mm3 - Female subjects of reproductive potential must have a negative serum or urine pregnancy test with a sensitivity of at most 50 mIU/mL performed within 30 days prior to Screening. - All subjects must agree not to participate in a conception process and use contraception. - Ability to communicate effectively with study personnel; considered reliable, willing, and cooperative in terms of compliance with the Protocol requirements. - Voluntary informed consent given to participate in the study. - Successful RNA amplification of at least 3 antigens (must include Gag). Exclusion Criteria: - HIV-2 antibody positive. - Positive test for other infectious diseases including: - clinically active, untreated syphilis (positive rapid plasma regain test (RPR) - clinically active hepatitis B infection (positive Hep B surface antigen HBsAg) - active hepatitis C infection or any history of hepatitis C infection - positive test for HTLV Type I or Type II antibody - Any acute infection or serious medical illness within 14 days prior to study entry - History of lymph node irradiation or dissection - Pregnancy or breast-feeding - Previous use of any HIV-1 immunotherapy, including IL-2 - Use of hydroxyurea within 30 days prior to Screening - Immunodeficiency other than HIV-1 or requirements to take immuno-modulating concomitant medications - Known allergy or sensitivity to the investigational immunotherapy or its formulation - Use of systemic corticosteroids and use of topical steroids over a total area exceeding 15 cm2 within 4 weeks of Screening or anticipated need for periodic use of corticosteroids during the study - Receipt of any immune modulators or suppressors within 30 days of Screening - Active autoimmune disease such as: - Rheumatoid arthritis - Inflammatory bowel disease - Systemic lupus erythematosis - Ankylosing spondylitis - Hashimoto's disease - Scleroderma - Multiple sclerosis - Autoimmune hemolytic anemia - Immune thrombocytopenic purpura - Type I diabetes mellitus (insulin therapy for Type II diabetes is permitted) - Participation in another clinical trial within 30 days of Screening or use of investigational agents (previous use of expanded access ARTs is permitted) - Body weight less than 30 kg. - Changes in ART regimen due to virologic failure (not including toxicities) - Presence of factors predicting insufficient adherence to the protocol. - Any condition that in the assessment of the investigator would indicate that it is not in the best interest of the subject or incompatible with the any aspect of the study design, treatment plan, and study objectives for a subject to participate. - History or other evidence of severe illness, malignancy, or any other condition that would make the subject, in the opinion of the investigator, unsuitable for the study.
