Adenovirus Vaccine for Malaria

Malaria is caused by a parasite carried by a mosquito. Currently, there is no vaccine licensed to prevent malaria. The purpose of this study is to find the most effective and safest dose of an experimental vaccine for the treatment of malaria. Participants will include 72 healthy adults, ages18 to 45, enrolled at Vanderbilt University Medical Center and Stanford University. Volunteers will receive 3 doses of either the malaria vaccine or placebo (contains no vaccine) by injection into a muscle at 0, 1 and 6 months. Investigators will evaluate how the body responds to increasing dosage strengths of the vaccine. Study procedures include physical exam, multiple blood draws, and completion of a memory aid (diary). Each participant will be actively involved in the study for about 12 months. Then, an annual phone call will be made to check for any serious illness events for a period of 5 years.

Stanford is currently not accepting patients for this trial.

   - History of moderate to severe mental illness, as defined by symptoms interfering with
   social or occupational function or suicidal thoughts/attempts.

   - History of receiving blood or blood products (such as blood transfusion, platelet
   transfusion, immunoglobulins, hyperimmune serum) in the previous 6 months.

   - Vaccination with a live vaccine within the past 30 days or with a nonreplicating,
   inactivated, or subunit vaccine within the last 14 days.

   - Known hypersensitivity to components of the vaccine.

   - History of acute or chronic medical conditions including, but not limited to,
   disorders of the liver, kidney, lung, heart, or nervous system, or other metabolic or

   - History of coagulation defect or bleeding from (bruising at) multiple sites that
   cannot be linked to trauma or surgery.

   - History of anaphylaxis or severe hypersensitivity reaction.

   - Severe asthma, as defined by an emergency room visit or hospitalization within the
   last 12 months.

   - Pregnant or breastfeeding women.

   - Acute illness, including temperature greater than 100 degrees Fahrenheit within one

   investigational product within the previous 30 days or planned receipt of an
   investigational product within 28 days following the last immunization dose.

   - Identification of any condition that, in the opinion of the investigator, would affect
   the ability of the subject to understand or comply with the study protocol or would
   jeopardize the safety or rights of a subject participating in the study.

   - History of malignancy, including hematologic and skin cancers (except for a localized
   basal cell carcinoma), or known immunodeficiency syndrome.

   - History of malaria infection or previous receipt of a malaria vaccine.

   - History of travel to malaria-endemic area or receipt of antimalarial prophylaxis in
   the past 12 months.

   - Planned travel to a malaria-endemic area prior to Visit 16 (Day 208).

   - Pre-medication with analgesic or antipyretic agents in the 6 hours prior to
   vaccination, or planned medication with analgesic or antipyretic in the 24 hours
   following vaccination. This criterion should not preclude subjects receiving such
   medication if the need arises.

   - Receipt of a recombinant adenovirus vector vaccine in a prior study.
