Clinical Trial Summary

The purpose of this study is to determine the safety of and immune response to a DNA HIV vaccine, pGA2/JS7, followed by a modified vaccinia (smallpox) HIV vaccine, MVA/HIV62, in HIV uninfected adults.

Description:

The worldwide HIV/AIDS epidemic may only be controlled through a safe and effective vaccine that will prevent HIV infection. DNA vaccines are inexpensive to construct, easily produced in large quantities, and stable for long periods of time. Recombinant modified vaccinia Ankara vaccines have been shown to be safe in humans, and immunogenicity after administration of both vaccines has been encouraging. When used together, a more robust immunologic response was associated with DNA HIV vaccine administration followed by modified vaccinia vaccine administration, compared to using either DNA or vaccinia vaccine alone. This study will evaluate the safety and immunogenicity of an experimental DNA HIV vaccine prime, pGA/JS7, followed by a similarly structured modified vaccinia boost, MVA/HIV62, in HIV uninfected adults. Participants in this study will be recruited only in the United States.

This study will be divided into 2 parts. Each participant will be involved with their part of study for 1 year. Participants in Part 1 will be randomly assigned to one of two different vaccination groups. Group 1A participants will be randomly assigned to receive either placebo or 2 lower doses of the DNA HIV vaccine (DNA) at study entry and Month 2, followed by 2 lower doses of the modified vaccinia vaccine (MVA) at Months 4 and 6. Group 1B will not enroll until safety and immunogenicity data from Group 1A have been evaluated. Group 1B participants will receive either placebo or two higher doses of DNA at study entry and Month 2, followed by two higher doses of MVA at Months 4 and 6.

Enrollment into Part 2 will begin only after safety data from Part 1 are reviewed. In Part 2, participants will be randomly assigned to one of two different vaccination groups. Within each group, participants will be randomly assigned to receive some series of vaccines or placebo. Group 2A participants will receive either placebo or the maximum tolerated dose (MTD) from Part 1 of DNA at study entry and MTD of MVA at Months 2 and 6. Group 2B participants will receive MTD of MVA at study entry and Months 2 and 6.

There will be 12 study visits over 12 months for Groups 1 and 2. There will be 11 study visits over 12 months for Groups 3 and 4. Medication history, a physical exam, an interview, HIV and pregnancy prevention counseling, and adverse events reporting will occur at all visits. Blood and urine collection and an electrocardiogram (ECG) will occur at selected visits.

• Current tuberculosis prophylaxis or therapy

• Clinically significant medical condition, abnormal physical exam findings, abnormal laboratory results, or past medical history that may affect current health

• Any medical, psychiatric, or social condition that would interfere with the study. More information about this criterion can be found in the protocol.

• Any job-related responsibility that would interfere with the study

• Allergy to egg products

• Serious adverse reaction to vaccines. A person who had an adverse reaction to pertussis vaccine as a child is not excluded.

• History of or known active cardiac disease. More information on this criterion can be found in the protocol.

• Electrocardiogram (ECG) with clinically significant findings OR features that would interfere with assessments for myocarditis or pericarditis. More information on this criterion can be found in the protocol.

• Two or more of the following cardiac risk factors: elevated blood cholesterol (defined as fasting low density lipoprotein [LDL] of greater than 160 mg/dl); first-degree relative (e.g., mother, father, brother, sister) who had coronary artery disease before the age of 50; current smoker; or body mass index (BMI) greater than 35

• Autoimmune disease or immunodeficiency

• Active syphilis infection. Participants whose syphilis infection was fully treated at least 6 months prior to study entry are not excluded.

• Severe and unstable asthma

• Diabetes mellitus type 1 or 2

• Thyroid disease requiring treatment

• Serious angioedema within the past 2 years

• Uncontrolled hypertension OR systolic blood pressure (BP) of 150 mmHg or greater or diastolic BP of 100 mmHg or greater

• BMI greater than 40

• Bleeding disorder

• Cancer. If a participant has had surgery to remove the cancer and, in the opinion of the investigator, the cancer is not likely to recur during the study period, the participant is not excluded.

• Seizure disorder

• Asplenia

• Mental illness that would interfere with compliance with the protocol

• Other conditions that, in the judgment of the investigator, would interfere with the study

• Pregnancy or breastfeeding, or plans to become pregnant
