Eligibility |
Inclusion Criteria: 1. Healthy male. 2. 18 to 45 years of age. 3. Willing to comply with the requirements of the protocol and available for follow-up for the planned duration of the study. 4. In the opinion of the Principal Investigator or designee and based on Assessment of Informed Consent Understanding results, has understood the information provided and has provided informed consent. 5. Willing to undergo HIV testing, risk reduction counseling and receive HIV test results. 6. All sexually active males must be willing to use male condoms with all sexual partners (female or male) from the day of first injection until 3 months after the injection. 7. Willing to forgo donations of blood or any other tissues during the study and, for those who test HIV-positive due to vaccine-induced antibodies, until the anti-HIV antibody titers become undetectable. Exclusion Criteria: 1. Confirmed HIV-1 or HIV-2 infection. 2. Any clinically relevant 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 investigator within the previous 6 months. 3. Any clinically significant acute or chronic medical condition that is considered progressive or in the opinion of the investigator makes the volunteer unsuitable for participation in the study. 4. Any of the following specific risk behaviour for HIV infection within 6 months prior to injection: - Unprotected sexual intercourse with a known HIV infected person or a partner known to be at high risk for HIV infection or a casual partner (i.e., no continuing established relationship) - Unprotected anal intercourse with another man (either insertive or receptive) - Three or more sexual partners - Engaged in sex work - Frequent excessive daily alcohol use or frequent binge drinking or chronic marijuana abuse or any other use of illicit drugs - History of newly-acquired syphilis, gonorrhea, non-gonococcal urethritis, HSV-2, chlamydia, epididymitis, proctitis, lymphogranuloma venereum, chancroid, or hepatitis B 5. Bleeding disorder that was diagnosed by a physician (e.g., factor deficiency, coagulopathy or platelet disorder that requires special precautions). 6. Clinically significant laboratory abnormalities. 7. Anti-AAV1 antibody level above the cut-off. 8. Receipt of live attenuated vaccine within the previous 60 days or planned receipt within 60 days after injection with IP; or receipt of other vaccine within the previous 14 days or planned receipt within 14 days after injection with IP (exception is live attenuated influenza vaccine within 14 days). 9. Receipt of blood transfusion or blood-derived products within the previous 3 months. 10. Participation in another clinical trial of an IMP currently, within the previous 3 months or expected participation during this study. 11. Prior receipt of another AAV vector, investigational HIV vaccine candidate, monoclonal antibody or polyclonal immunoglobulin (note: receipt of placebo in a previous HIV vaccine or monoclonal antibody trial will not exclude a volunteer from participation). 12. History of severe local or systemic reactogenicity to vaccines or infusions (e.g., anaphylaxis, respiratory difficulties, angioedema) 13. Psychiatric condition that compromises safety of the volunteer and precludes compliance with the protocol. 14. In the opinion of the Principal Investigator, it is not in the best interest of the volunteer to participate in the trial. 15. Seizure disorder: a participant who has had a seizure in the last 3 years. 16. ECG with clinically significant findings or features. 17. History of, or known active cardiovascular disease. 18. Have 3 or more of the following risk factors: - Hypertension diagnosed by a doctor - Hypercholesterolemia diagnosed by a doctor - Diabetes mellitus - Hyperglycemia diagnosed by a doctor - First degree relative (i.e., mother, father, brother, sister) who had a heart condition before the age of 50 - Currently smoke cigarettes |
