Study to Evaluate the Safety, Tolerability and Immunogenicity of Recombinant Botulinum Vaccine A/B in Healthy Adults

Completed · Phase 1

Conditions studied: RECOMBINANT BOTULINUM VACCINE A/B

In brief

The purpose of this trial is to evaluate the safety and tolerability of a two-dose regimen (Day 0 and Day 28) of recombinant Botulinum Vaccine (rBV) A/B in healthy volunteers when given intramuscularly at three ascending dosage levels by cohort and a two-dose regimen (Day 0 and Day 28) of a formulation containing only antigens at the 40 ug total immunizing protein dosage level.

Who can join

Age: 18 and older, up to 40. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• The volunteer is between 18 to 40 (inclusive) years of age at the time of the first dose of rBV A/B.
• The volunteer is in good health as determined by the Investigator (Study Doctor) from a medical history and physical examination.
• The volunteer has clinical chemistry, hematology and urinalysis laboratory values within 10 % above the upper or within 10 % below the lower limit of the normal range as established by the University of Kentucky clinical laboratory which are not considered clinically significant by the Investigator and/or the Sponsor Medical Monitor.
• The volunteer has a normal electrocardiogram (ECG). However, if a potential volunteer is reported to have a benign ECG abnormality (e.g., sinus bradycardia) the results may be discussed with the Sponsor Medical Monitor. With the agreement of the Sponsor Medical Monitor and documentation of the consultation in the volunteer's study record, the Investigator may include the volunteer in the study.
• The volunteer is willing to have his or her blood samples stored for future botulinum research studies.
• The volunteer has signed the Informed Consent Form, successfully completed (at least 90 % correct) the Test of Understanding, and has signed the Health Insurance Portability and Accountability Act (HIPAA) authorization form.
• The volunteer agrees not to donate blood for at least 30 days following vaccination.
• The volunteer is willing to comply with the requirements of the protocol through the post-vaccination Day 168 (± 7 days) visit.
• Female volunteers must be of non-childbearing potential (i.e., surgically sterilized or postmenopausal), or must not be pregnant (as indicated by a negative serum pregnancy test within 24 hours prior to rBV A/B administration) or nursing, and must use two types of acceptable form of FDA-approved birth control methods including: 1) hormonal types of birth control (such as implants or birth control pills) or an intrauterine device (IUD) and 2) an additional barrier type of birth control measure (i.e. condoms, diaphragms, cervical caps, spermicide, etc.) during the period beginning from 30 days before vaccination through completion of the study. Completion of the study is defined as completing the post-vaccination Day 168 (± 7 days) visit.

You may not qualify if…

• The volunteer has frequent or severe headaches of any etiology.
• The volunteer has chronic, severe or recurrent joint pain or arthritis of any etiology.
• The volunteer has a history of alcohol or drug abuse within the 12 months prior to study screening or any history of injectable drug use.
• The volunteer has a positive result on a urine drug screen that tests for common substances of abuse such as amphetamines, barbiturates, benzodiazepines, cocaine, opiates, and cannabinoids. (If positive on screen, confirmatory testing shall be performed where applicable).
• The volunteer has a previous diagnosis of any serious psychiatric disorder. For this purpose, serious psychiatric disorder is defined as illness requiring hospitalization within the previous 12 months; routine administration of more than one medication to control anxiety, mood or sleep disorder; or history of suicide attempt.
• The volunteer has received any blood products or immune globulin in the previous six months.
• The volunteer has donated blood within the past 56 days.
• The volunteer received any investigational drug therapy within 30 days before the first dose of rBV A/B or intends to receive any other investigational drug therapy before the post-vaccination Day 168 (± 7 days) visit.
• Licensed vaccines are not exclusionary but should be given at least 30 days before or after immunization (if live vaccine: 60 days before or after immunization) to avoid potential confusion of adverse reactions.
• The volunteer has received any other investigational Botulinum Vaccine or Toxoid.
• The volunteer has received previous treatment with approved therapeutic products containing botulinum neurotoxins such as Botox, Myobloc, and Botox Cosmetic.
• The volunteer has a clinically significant abnormality on the ECG.
• The volunteer has a known hypersensitivity to aluminum compounds or yeast.
• The volunteer has any laboratory values greater than 10 % above the upper or greater than 10 % below the lower limit of normal or clinically significant as assessed by the Investigator and/or Sponsor Medical Monitor.
• The volunteer tests positive for Human Immunodeficiency Virus (HIV); Hepatitis C Virus (HCV) or Hepatitis B surface Antigen (HBsAg).
• The volunteer has a body mass index > 40 kg/m2 or is > 100 lbs. over ideal body weight.
• The volunteer has an acute illness, evidence of significant active infection, or evidence of systemic disease at time of enrollment that in the opinion of the Investigator would place the volunteer at an unacceptable risk for injury.
• The volunteer has a temperature > 100.4 °F at the time of enrollment.
• The volunteer has occupational or other responsibilities that would prevent completion of participation in the study.
• The volunteer has a history of anaphylaxis or other serious adverse reactions to vaccines.
• The volunteer has a personal or family history of multiple sclerosis.
• The female volunteer is pregnant (must have a negative serum pregnancy test within 24 hours prior to each dose of rBV A/B), lactating or unwilling to use two types of an acceptable form of FDA-approved contraception for 30 days prior to first dose of rBV A/B through the post-vaccination Day 168 (± 7 days) visit.
• The volunteer requires chemotherapeutic and immunosuppressive agents or a total corticosteroid dose of 2 mg/kg or 20 mg/day within the 3 months prior to the study or burst steroid therapy within 14 days before vaccination.
• The volunteer is currently on active duty in the US military.
• The volunteer is a US military veteran that received other botulinum products for vaccination or research purposes.
