- Had two or fewer partners believed to be HIV-uninfected and who did not use illicit drugs (as defined above) and with whom he/she regularly used condoms for vaginal and anal intercourse;
- If sexually active female, using an effective method of contraception (combined oral contraceptive pill; injectable contraceptive; diaphragm; Intra Uterine Device (IUD); condoms; anatomical sterility in self or partner) throughout the study period. All female volunteers must be willing to undergo urine pregnancy tests at time points as indicated

Exclusion Criteria:
- Confirmed HIV-1 or HIV-2 infection

- Any clinically significant acute or chronic medical condition requiring care of a physician (e.g., diabetes, coronary artery disease, rheumatologic illness, malignancy, substance abuse) that in the opinion of the investigator would preclude participation
- Any laboratory value outside of reference range, with the exception of any non-clinically significant Grade I elevations of liver function tests (AST, ALT, direct/total bilirubin), electrolytes, CO2, CBC, urinalysis as determined by the Principal Investigator or his designee as well as creatinine if the estimated glomerular filtration rate is > 60 mL/min/1.73 m2
- Within the 12 months prior to enrollment, the volunteer has had excessive daily alcohol use or frequent binge drinking or chronic marijuana abuse or any other use of illicit drugs
- Within the 12 months prior to enrollment, the volunteer has a history of newly-acquired syphilis, gonorrhea, non-gonococcal urethritis, herpes simplex virus type 2 (HSV2), Chlamydia, pelvic inflammatory disease (PID), trichomonas, mucopurulent cervicitis, epididymitis, proctitis, lymphogranuloma venereum, chancroid, hepatitis B (surface antigen, HbsAg) or hepatitis C (HCV antibodies)
- If female, pregnant, planning a pregnancy during the trial period, or lactating
- Receipt of a live attenuated vaccine within 30 days or other vaccine within 14 days prior to DEC-205 vaccination
- Receipt of another experimental HIV vaccine at any time
- Receipt of blood transfusion or blood products 6 months prior to vaccination
- Participation in another clinical study of an investigational product currently or within past 12 weeks, or expected participation during this study
- History of severe local or systemic reactogenicity to vaccination or history of severe allergic reactions
- Major psychiatric illness
- In the opinion of the investigator, unlikely to comply with protocol

5. Study Description
Brief Summary
DCVax-001 is a recombinant protein vaccine designed to prevent and potentially treat human immunodeficiency virus (HIV) infection. The vaccine is composed of a fusion protein containing a human monoclonal antibody specific for the dendritic cell receptor, DEC-205 (CD205), and the HIV gag p24 protein. The vaccine is designed to target HIV antigens directly to endocytic pathways in dendritic cells (DCs) that allow for efficient processing and presentation of multiple HIV peptides on both MHC class I and II products, which will induce HIV-specific CD8+ and CD4+ T cells. This vaccine candidate must be combined with appropriate immunostimulants (adjuvants) to induce immunity to the antigen. In the proposed clinical trial we will use poly ICLC (Hiltonol) from Oncovir, Inc as the adjuvant.
Detailed Description
This trial will investigate whether delivery of HIV antigens via immunization with anti-DEC-205 p24 monoclonal antibody plus poly ICLC, as an adjuvant, is safe and induces either cellular or humoral immunogenicity in healthy volunteers. We propose to assess the quality of immunity elicited by DEC targeted vaccines in humans. Immunogenicity after HIV antigen delivery directly to dendritic cells could provide the proof-of-concept that dendritic cell targeted protein vaccines may serve as a stand-alone vaccine strategy or in combination with other vaccine modalities against HIV or other diseases.
The main hypothesis of this study is to assess the delivery of HIV antigens via immunization with anti-DEC-205 p24 monoclonal antibody (DCVax-001) plus poly ICLC (Hiltonol) is safe and induces either cellular or humoral immunogenicity in HIV-uninfected, healthy volunteers.
