Detoxified J5 Core Glycolipid/ Group B Meningococcal Outer Membrane Protein Vaccine for Gram-negative Bacterial Sepsis Administered With and Without Synthetic CPG Oligodeoxynucleotide 7909 Adjuvant
A Randomized, Partial-Blinded, Placebo-Controlled, Phase I Safety and Immunogenicity Study in Healthy Subjects of Detoxified J5 Core Glycolipid/ Group B Meningococcal Outer Membrane Protein Vaccine for Gram Negative Bacterial Sepsis Administered With and Without Synthetic CPG Oligodeoxynucleotide 7909 Adjuvant

Brief Summary
The purpose of this study is to test the safety of an experimental vaccine against sepsis (infection of the blood) alone and with an experimental adjuvant (a substance that may improve vaccine effectiveness). This study will also find out how well antibodies are made after receiving vaccine alone or vaccine combined with adjuvant. Participants will include up to 34 healthy volunteers between the ages 18-50 years. Participants will be randomly assigned to 1 of 4 groups to receive vaccine alone, vaccine with adjuvant (2 different dosages) or placebo (inactive substance). Participants will receive 3 vaccinations at different times during the study (Day 0, Day 29 and Day 59). Study procedures will include blood samples, urine samples, electrocardiogram (measures heart activity) and a completion of a memory aid to document side effects. Participation will involve 16 clinic visits and 3 follow-up telephone calls over 12 months.

Outcome Measures
Primary Outcomes (1)
Clinical measures: severity and duration of systemic and local adverse events (AEs), and vaccine-related serious adverse events (SAEs)
Solicited local and systemic adverse events (AEs) within 8 days post vaccination (Day 0-7); vaccine-related serious adverse events (SAEs) throughout the course of the study.
Secondary Outcomes (1)
Immunogenicity measures: mean fold-increase in anti-J5 detoxified lipopolysaccharide (dLPS) IgG and IgM levels in serum and percent of subjects having >/= 4-fold IgG and IgM antibody titer response, time to seroconversion.
Blood sampling Days 0, 14, 36, 66, 120, 180 and 365.
Study Arms (4)
Group 1 - vaccine alone
ACTIVE COMPARATOR8 subjects to receive vaccine (10 mcg) alone on Days 0, 29 and 59.
Group 3 - vaccine + CPG 7909 (250 mcg)
EXPERIMENTAL8 subjects to receive vaccine (10 mcg) with 250 mcg of adjuvant on Days 0, 29 and 59.
Group 2 - vaccine + CPG 7909 (500 mcg)
EXPERIMENTAL8 subjects to receive vaccine (10 mcg) with 500 mcg of adjuvant on Days 0, 29 and 59.
Group 4 - Placebo
PLACEBO COMPARATOR4 subjects to receive normal saline (placebo) on Days 0, 29 and 59.
Interventions
CPG 7909 is a synthetic oligodeoxynucleotide used as an adjuvant and administered at 2 different dosages: 250 mcg and 500 mcg.
J5-OMP vaccine 10 mcg to be administered with and without CpG 7909 adjuvant 250 or 500 mcg, intramuscularly on Days 0, 29 and 59.
Eligibility Criteria
You may qualify if:
- Male or female ages 18-50 years, inclusive.
- The subject has provided written informed consent prior to any study procedures.
- Able to attend scheduled visits and comply with trial procedures.
- Women of child-bearing potential or their partners must be surgically sterile or must agree to use an effective method of contraception and agree to remain on that same method through Day 120. Male subjects or their partners must be surgically sterile or must agree to use effective contraception through Day 120. (e.g. hormonal contraceptives initiated at least 30 days prior to receipt of vaccine, intrauterine devices (IUDs), diaphragm in combination with contraceptive jelly, condoms in combination with contraceptive jelly, cream, or foam; or vasectomized partner).
- Have normal laboratory values for hemoglobin, white blood cells (WBC) and platelets, absolute neutrophil count (ANC), absolute lymphocyte count (ALC) obtained from the complete blood count (CBC), and serum glucose and thyroid stimulating hormone (TSH). Serum alkaline phosphatase, aspartate aminotransferase (AST), alanine transferase (ALT), blood urea nitrogen (BUN), C-reactive protein (CRP) and creatinine are not to exceed the upper limit of normal, and urinalysis must be normal on day of screening visit.
- Must have a negative pregnancy test at screening (serum) and negative pregnancy test (urine) on days of vaccination, with known results prior to vaccination.
- Subject agrees to avoid non-study related blood donation for 1 year following the last immunization.
You may not qualify if:
- History of allergy or severe reaction to any vaccine or vaccine components or unmethylated cytosine-guanosine motif (CPG) components.
- Acute illness or fever \>/= 38 degrees Celsius/100.4 degrees Fahrenheit within a week prior to each vaccination.
- Prior receipt of any Group B meningococcal outer membrane protein (OMP) vaccine.
- Previous receipt of oligodeoxynucleotide adjuvant including CPG.7909.
- Immunosuppression as a result of underlying illness or treatment.
- Use of oral steroids, parenteral steroid or high-dose inhaled (\>800 mcg/day of beclomethasone dipropionate or equivalent) within 30 days prior to each vaccination.
- Acute or chronic condition that (in the opinion of the investigator) would render vaccination unsafe or would interfere with the evaluation of responses including, but not limited to the following: cardiovascular, known chronic liver disease, significant renal disease, chronic lung diseases, unstable neurologic disorder.
- Receipt of immunoglobulin or other blood product within 3 months prior to enrollment.
- Current excessive use of alcohol or drug dependence (\>8 ounces of liquor or \>96 ounces of beer/day) or a history of alcohol or drug abuse in the 5 years prior to enrollment.
- History of meningococcal infection.
- Diagnosed autoimmune condition in either subject or immediate family member.
- Under the care of a physician for a diagnosed psychiatric condition.
- Women who are pregnant or breast feeding.
- Women with a current or recent (i.e. within two half-lives) history of diuretic or promethazine use.
- The subject is immunosuppressed as a result of an underlying illness or treatment with immunosuppressive or cytotoxic drugs, or use of anticancer chemotherapy or radiation therapy within the preceding 36 months.
