Further study details as provided by Aeras.

Inclusion criteria

• Age 21 years through 45 years (i.e., subject had not yet reached his/her 46th birthday at day of randomization).
• Had completed the written informed consent process prior to undergoing any screening evaluations.

• Females: Ability to avoid pregnancy for at least 6 months after receiving the last study vaccination: Women physically capable of pregnancy (not sterilized and still menstruating or within 1 year of the last menses if menopausal) must have avoided pregnancy from 28 days prior to administration of the study vaccine and must have agreed to avoid pregnancy through at least 6 months after receiving the last study vaccination. Acceptable methods of avoiding pregnancy included a sterile sexual partner, sexual abstinence (not engaging in sexual intercourse), or use of a combination of at least two forms of acceptable contraception: hormonal contraceptives (oral, injection, transdermal patch, or implant), vaginal ring, intrauterine device (IUD), and the use of a condom or a diaphragm; or the use of a condom or a diaphragm combined with spermicide.
• Was able to carry out activities of daily living independently.
• Had Body Mass Index (BMI) of at least 19 (wt./ht.2) by nomogram.
• Had ability to complete follow-up period as required by the protocol.
• Was able and willing to commit to avoiding elective surgery for at least 6 months after receiving the last study vaccination.
• Was able and willing to stay in contact with the study site for the duration of the study.
• Had committed to simultaneous enrollment in Aeras Vaccine Development Registry Protocol.
• Had laboratory evidence of human immunodeficiency virus (HIV) infection, defined as a positive HIV-1 ELISA test plus a positive confirmatory test (e.g., a second HIV-1 ELISA, PCR, or rapid ELISA).
• Had four (4) (for Group 1) or three (3) (for Group 2)* CD4+ lymphocyte count tests, each performed at least four days apart within the 42-day screening period, with at least three (for Group 1) or two (for Group 2) CD4+ lymphocyte count results greater than 350 cells / mm3.
• Not currently receiving antiretroviral drugs.
• Committed to not participate in any other clinical trials during the first 12 months of participation in this study.

• Used immunosuppressive medication within 42 days prior to randomization (inhaled and topical corticosteroids were permitted).
• Received immunoglobulin or blood products within 42 days prior to randomization.
• Received any investigational drug therapy or vaccine within 182 days prior to randomization.
• History of having received any adenovirus-vector-based vaccine.
• Medical history that may have compromised the evaluation of safety of the subject in the study (e.g., diabetes, seizure disorder, sickle cell disease).
• Pregnant or breastfeeding female, or intention to become pregnant during the study within 6 months after receiving the last study vaccination.
