Phase 1 PK Study of XOMA 3AB

Completed · Phase 1 · Has a placebo group

Conditions studied: Botulism

In brief

This is a phase I, single-center, placebo-controlled, double-blinded, dose escalation study of anti-botulinum toxin monoclonal antibodies in healthy adult volunteers. Volunteers will be hospitalized in the Johns Hopkins Phase 1 unit during the infusion and until after the 24-hour blood draw. Three escalating dose cohorts of a combination of three anti-botulinum monoclonal antibodies will be evaluated. Each cohort will consist of eight volunteers in which they will receive a single intravenous infusion of active drug or placebo. Placebo will be normal saline. Volunteers will be followed for safety for up to 120 days after infusion depending on dose cohort.

Who can join

Age: 18 and older, up to 45. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Informed consent understood and signed
• Healthy male or healthy, non-pregnant, non-lactating female
• Willingness to comply and be available for all protocol procedures
• Age between 18 and 45 years, inclusive on the day of infusion
• Body Mass Index of < 35
• Blood pressure within acceptable limits (systolic blood pressure </=140mmHg and diastolic blood pressure </=90mmHg). If subject is receiving anti-hypertensive medications, blood pressure must be well controlled with no changes in anti-hypertensive medications for at least 3 months.
• If the subject is female and of childbearing potential, negative serum pregnancy test at screening and negative urine or serum pregnancy test within 24 hours prior to infusion.
• If the subject is female and of childbearing potential, she agrees to practice abstinence from sexual intercourse with men or use acceptable contraception, for the duration of the study:
• A woman is considered of childbearing potential unless post-menopausal (>/= 1 year without menses) or surgically sterilized (tubal ligation, bilateral oophorectomy, or hysterectomy)
• Acceptable contraception methods are restricted to effective devices (Intrauterine Contraceptive Devices (IUDs), NuvaRing®) or licensed hormonal products with use of method for a minimum of 30 days prior to vaccination, condoms with spermicidal agents, monogamous relationship with a vasectomized partner, or successful Essure placement with documented confirmation test at least 3 months after the procedure.
• All requested screening laboratory values are within the range specified in the table, "Acceptable Ranges of Screening Labs and Vital Sign Measurements" (Appendix B).
• Has adequate venous access for the infusion.
• The drug screen is negative
• Breathalyzer test is negative.

You may not qualify if…

• History of a chronic medical conditions including, but not limited to, disorders of the liver, kidney, lung, heart or nervous system, or other metabolic and autoimmune/inflammatory conditions that would either interfere with the accurate assessment of the objectives of the study or increase the risk profile of the subject such as:
• Diabetes
• Asthma requiring use of medication in the year before screening
• Autoimmune disorder, such as lupus, Wegener's, rheumatoid arthritis
• Coronary artery disease
• History of malignancy except low-grade (squamous and basal cell) skin cancer thought to be cured
• Chronic renal hepatic or pulmonary disease (except previous asthma which has required no treatment for the past year)
• History of severe allergic reaction of any type to medications, bee stings, food, or environmental factors or hypersensitivity or reaction to immunoglobulins. Severe allergic reaction is defined as any of the following:
• Anaphylaxis
• Urticaria
• Angioedema
• A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >450 milliseconds)
• Clinically significant abnormal electrocardiogram at screening in the judgment of the investigator
• Positive serology results for Human Immunodeficiency Virus (HIV), Hepatitis B Surface Antigen (HBsAg), or Hepatitis C Virus (HCV) antibodies
• Febrile illness with temperature >37.6°C within 7 days of dosing
• Pregnant or breastfeeding
• Donated blood within 56 days of enrollment
• Known allergic reactions to any of the study product components present in the formulation or in the processing, as listed in the Investigator Brochure.
• Treatment with another investigational drug within 30 days of dosing
• Receipt of a monoclonal antibody at any time in the past
• Receipt of antibody (e.g. TIG, VZIG, IVIG, IM gamma globulin) or blood transfusion within 6 months or within 5 half-lives of the specific product given
• Receipt of any live vaccines within the previous 3 months or within 5 half-lives of the specific vaccine given
• Receipt of any killed vaccines within the previous 1 month
• Lack of ability to fully understand the informed consent (e.g. cannot speak or read English)
• Active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements.
