Overview
Brief Summary
The primary objective is to determine the safety and tolerability of single, ascending intravenous doses of ch-mAb7F9 in healthy subjects via physical examinations and adverse event, vital sign, electrocardiogram (ECG), and clinical laboratory testing.Phase 1a, randomized, placebo-controlled, first-in-human (FIH) study of intravenously administered ch-mAb7F9. The study will be a double-blind, dose-escalation study. Each subject will receive a single dose of ch-mAb7F9 or placebo (saline).
Detailed Description
There will be 5 dose groups. At the beginning of dosing in each group, 1 subject will receive the normal saline placebo and 1 will receive the active dose. The remainder of the dose group will receive their doses beginning 48 hr later, after safety evaluations. Dosing of the remaining subjects in each dose group will occur 1 at a time, with dosing in each subsequent subject separated by a minimum of 24 hr. Subsequent dose groups will receive their doses beginning approximately 2 weeks after dosing in the preceding group, pending safety analyses. The single doses to be administered in each cohort are 0.2, 0.6, 2, 6, and 20 mg/kg, respectively. The starting dose will be 0.2 mg/kg, and the highest dose will be 20 mg/kg (up to a maximum of 1,500 mg), which is at least 20-fold lower than the no observable adverse effect level (NOAEL) in rats to ensure subject safety. Ch-mAb7F9 will be administered intravenously (IV) with a saline flush to clear the administration tubing of residual ch-mAb7F9. Each dose of ch-mAb7F9 will be diluted in 225 ml of saline and given over two hours.

Eligibility Criteria
Inclusion Criteria
- •Subjects with the following criteria may be considered for inclusion in the study:
- •Subject voluntarily agrees to participate in this study and signs an IRB-approved informed consent form prior to performing any of the screening procedures.
- •Healthy, determined by the PI based on pre-study medical evaluation (medical history and physical examination, vital signs, ECG, and clinical laboratory evaluations).
- •Males or females between 18 to 50 years of age, inclusive.
- •The following applies to female subjects:
- •Nonchildbearing potential (surgically sterile \[hysterectomy, bilateral oophorectomy, or bilateral tubal ligation/occlusion\] or post-menopausal 1 year with follicle stimulating hormone \[FSH\] \> 40 U/L).
- •Nonpregnant, nonlactating females of childbearing age who agree to use medically acceptable forms of birth control (oral contraceptive pills; contraceptive patches; vaginal ring; diaphragm, sponge, or condom with spermicide; hormone injection; or intrauterine device) from screening to end of study follow-up, or whose partner has had a vasectomy.
- •The following applies to male subjects:
- •Need to have had a vasectomy or agree to use a condom and spermicide in addition to their female partners using a form of birth control.
- •Agree not to donate sperm for 90 days post dose.
Exclusion Criteria
- •Subjects presenting with any of the following will not be included in the study:
- •A history of treatment with a monoclonal antibody in the past year,
- •likely allergy or sensitivity to ch-mAb7F9 based on known allergies to other mAbs, or which, in the opinion of the Principal Investigator (PI), suggests an increased potential for an adverse hypersensitivity to ch-mAb7F9,
- •a history of severe allergy (rash, hives, breathing difficulty, etc.) to any medications, either prescription or nonprescription, including dietary supplements or herbal medications,
- •a history of allergic or environmental bronchial asthma,
- •a clinically significant history of or current abnormality or disease of any organ system, including renal, hepatic, gastrointestinal, cardiovascular, pulmonary (including chronic asthma), endocrine (eg, diabetes), central nervous, or hematologic systems, or recent clinically significant surgery,
- •a history of seizure, epilepsy, severe head injury in the opinion of the PI, multiple sclerosis, or other known neurological conditions,
- •abnormal pre-admission vital signs, physical examination, clinical laboratory, or any safety variable which is considered clinically significant for this population by the PI or Sponsor (or designee), (volunteers who have or are suspected to have Gilbert's syndrome will be discussed on a case by case basis by the PI, Medical Monitor, and Sponsor),
- •a planned or scheduled surgical procedure during the study,
- •a clinically significant mental or physical illness within 1 year prior to the first dose, including a history of alcohol and/or drug abuse (DSM IV criteria) within 1 year prior to the first dose of study medication,
