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.

Eligibility Criteria

• Age: 18 Years - 60 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Healthy adult males and females, as assessed by a medical history, physical exam, and laboratory tests
• Age of at least 18 years of age on the day of screening and no greater than 60 years at time of vaccination
• Willing to comply with the requirements of the protocol and available for follow-up for the planned duration of the study (screening plus 15 months)
• In the opinion of the principal investigator or designee, has understood the information provided. (Written informed consent needs to be given before any study-related procedures are performed)
• Amenable to HIV risk reduction counseling, committed to maintaining behavior consistent with low risk of HIV exposure through the last required protocol clinic visit
• Assessed by the clinic staff as being at "low risk" for HIV infection on the basis of sexual behaviors within the 12 months prior to enrollment defined as follows:
• Sexually abstinent OR
• Had two or fewer mutually monogamous relationships with partners believed to be HIV-uninfected and who did not use illicit drugs (illicit drug use or abuse that includes any injection drugs, methamphetamines (crystal meth), heroin, cocaine, including crack cocaine or chronic marijuana abuse) OR
• 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
• If sexually active male, willing to use an effective method of contraception (such as condoms, anatomical sterility) from screening until 4 weeks after last vaccination (same as above) and will be advised not to get his partner(s) pregnant

You may not qualify if:

• Confirmed HIV-1 or HIV-2 infection
• Any clinically significant abnormality on history or examination including history of immunodeficiency or autoimmune disease; use of systemic corticosteroids immunosuppressive anticancer, or other medications considered significant by the trial physician within the last 6 months
• 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
