Randomized, Open-label Phase II Trial to Assess the Safety and Immunogenicity of MVA-BN Smallpox Vaccine When Increasing the Number of Injections Compared to the Standard Regimen in Immunocompromised Subjects With HIV Infection

The main purpose of this clinical trial is to generate additional safety data in a highly
immunocompromised population. HIV-infected persons are considered excellent candidates to
represent the highly immunocompromised population for enrolment in this trial. Additionally,
the immune system's response (protection against smallpox as measured by the amount of
antibodies produced) following injections of MVA-BN® smallpox vaccine will be evaluated. All
participants in this trial will be randomly and evenly assigned to one of three groups to
receive two, three or four injections. Group 1 will receive the standard regime consisting of
one dose at each vaccination time point, Group 2 will receive two doses at each vaccination
time point and Group 3 will receive a booster vaccination 12 weeks after the first dose of
the standard vaccination schedule with MVA-BN® smallpox vaccine. Participation in the trial
is scheduled to last up to 48 weeks.


Inclusion Criteria:

1. Male and female subjects aged between 18-45 years, vaccinia-naïve. 2. HIV-1 infection
documented by ELISA and confirmed by Western blot at any time prior to study entry. HIV-1
deoxyribonucleic acid (DNA) polymerase chain reaction (PCR), HIV-1 culture, HIV-1 antigen,
plasma HIV-1 ribonucleic acid (RNA), or a second antibody test other than ELISA is
acceptable as an alternative test at any time prior to study entry.

3. On stable antiretroviral therapy (ART) i.e. Combination ART for at least 6 months.
Subject must be on the same ART regimen for at least 12 weeks with no change prior to
enrollment in this clinical trial.

4. Screening HIV-1 RNA < 200 copies/ml by US Food and Drug Administration (FDA) approved
PCR assay within 45 days prior to study entry.

5. Current CD4 counts ≥ 100 cells/µl ≤ 500 cells/µl. 6. Documented nadir CD4 count < 200
cells/µl at any time prior to enrollment. 7. Hemoglobin ≥ 9.0 g/dl for female subjects, ≥
10.0 g/dl or male subjects. 8. Platelets ≥ 100,000/mm3. 9. Ability and willingness of
subject to provide written informed consent. 10. Body Mass Index (BMI) ≥ 18.5 and < 35
kg/m2. 11. Women of childbearing potential (WOCBP) must have used an acceptable method of
contraception for 30 days prior to the first vaccination, must agree to use an acceptable
method of contraception during the trial, and must avoid becoming pregnant for at least 28
days after the last vaccination. A woman is considered of childbearing potential unless
post-menopausal (defined as ≥ 12 months without a menstrual period) or surgically
sterilized. Acceptable contraception methods are restricted to abstinence, barrier
contraceptives, intrauterine contraceptive devices or licensed hormonal products).

12. WOCBP must have a negative serum pregnancy test at screening (SCR) and a negative urine
pregnancy test within 24 hours prior to each vaccination.

13. Absolute neutrophil count cells ≥ 750/mm3. 14. Adequate renal function defined as a
calculated Creatinine Clearance (CrCl) > 60 ml/min as estimated by the Cockcroft-Gault
equation.

1. For men: (140 - age in years) x (body weight in kg) ÷ (serum creatinine in mg/dl x 72)
= CrCl (ml/min)

2. For women: multiply the result by 0.85 = CrCl (ml/min).Adequate hepatic function
defined as: Total bilirubin ≤ 2 x upper limit normal (ULN) in the absence of other
evidence of significant liver disease

15. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline
phosphatase ≤ 2.5 x ULN.

16. Troponin I < 2 x ULN at entry in the clinical trial. 17. Electrocardiogram (ECG)
without clinically significant findings (e.g. any kind of atrioventricular or
intraventricular conditions or blocks such as complete left or right bundle branch
block, AV node block, QTc or PR prolongation, premature atrial contractions or other
atrial arrhythmia, sustained ventricular arrhythmia, two premature ventricular
contractions (PVC) in a row, ST elevation consistent with ischemia).

Exclusion Criteria:1. Pregnant or breast-feeding women. 2. Typical vaccinia scar. 3.
Known or suspected history of smallpox vaccination. 4. History of vaccination with any
poxvirus-based vaccine. 5. Uncontrolled serious infection, i.e. not responding to
antimicrobial therapy.

6. History of any serious medical condition, which in the opinion of the investigator
would compromise the safety of the subject or would limit the subject's ability to
complete the trial including uncontrolled diabetes as according to the 'Division of
Acquired Immune Deficiency Syndrome (AIDS) Table for Grading the Severity of Adult and
Pediatric Adverse Events' Version 1.0, December 2004, Clarification August 2009.

7. History of or active autoimmune disease, persons with vitiligo or thyroid disease
taking thyroid replacement are not excluded.

8. Known or suspected impairment of immunologic function except those defined in the
inclusion criteria, including, but not limited to clinically significant liver
disease, diabetes mellitus type I and moderate to severe kidney impairment.

9. History of malignancy other than squamous cell or basal cell skin cancer, unless
there has been surgical excision that is considered to have achieved cure. Subjects
with history of skin cancer must not be vaccinated at the previous tumor site.

10. History or clinical manifestation of clinically significant and severe
hematological, pulmonary, central nervous, cardiovascular or gastrointestinal
disorders (except HIV infection, chronic or active Hepatitis-B-Virus or
Hepatitis-C-Virus infection).

11. Clinically significant psychiatric disorder not adequately controlled by medical
treatment.

12. History of coronary heart disease, myocardial infarction, angina pectoris,
congestive heart failure, cardiomyopathy, stroke or transient ischemic attack,
uncontrolled high blood pressure, or any other heart condition under the care of a
doctor.

13. Known history of an immediate family member (father, mother, brother, or sister)
who has had onset of ischemic heart disease before age 50 years.

14. Ten percent or greater risk of developing a myocardial infarction or coronary
death within the next 10 years using the National Cholesterol Education Program's risk
assessment tool (http://hin.nhlbi.nih.gov/atpiii/calculator.asp?usertype=prof). NOTE:
This criterion applies only to subjects 20 years of age and older.

15. Current alcohol abuse (40 g/day for at least 6 month) and/or intravenous and/or
intranasal drug abuse (within the past 6 months).

16. Known allergy to MVA-BN® vaccine or any of its constituents, e.g. tris
(hydroxymethyl)-amino methane, including known allergy to egg or aminoglycosides.

17. History of anaphylaxis or severe allergic reaction to any vaccine. 18. Acute
disease (illness with or without a fever) at the time of enrollment. 19. Body
temperature ≥ 100.4°F (≥ 38.0°C) at the time of enrollment. 20. Having received any
vaccinations or planned vaccinations with a live vaccine within 30 days prior to or
after trial vaccination.

21. Having received any vaccinations or planned vaccinations with a killed vaccine
within 14 days prior to or after trial vaccination.

22. Use of immunosuppressant or immunomodulatory agents including systemic
glucocorticoids (excluding nasal or inhaled steroids), tacrolimus, sirolimus,
rapamycin, mycophenolate, cyclosporine, TNF-alpha blockers or antagonists,

prior to enrollment in this clinical trial.

23. Post organ transplant subjects whether or not receiving chronic immunosuppressive
therapy.

24. Administration or planned administration of immunoglobulins and/or any blood
products during a period starting from three months prior to administration of the
vaccine and ending at last physical trial visit.

25. Use of any investigational or non-registered drug or vaccine other than the trial
vaccine within 30 days preceding the first dose of the trial vaccine, or planned
administration of such a drug during the trial period.
