60 subjects to receive Omr-IgG-am.
Omr-IgG-am™ 5% is provided in 100 ml bottles (5.0 grams) as a sterile solution containing 5% protein, 10% maltose and water for injection. This product is licensed in Israel, but not in the US.
Active Comparator: 2
20 subjects to receive Polygam® S/D (IVIG).
Drug: Polygam® S/D
Polygam® S/D is a solvent/detergent treated, sterile, freeze-dried preparation of highly purified immunoglobulin G (IgG) derived from large pools of human plasma. When reconstituted (5%) with the supplied diluent (sterile water for injection, USP) Polygam® S/D contains approximately 50mg of protein per ml (approximately 90% is gamma globulin); 3mg/ml human albumin, 22.5 mg/ml glycine, 20 mg/ml glucose, 2mlg/ml polyethylene glycol (PEG), 1 mcg/ml tri-nbutyl phosphate, 1 mcg/ml octoxynol 9, and 100 mcg/ml polysorbate 80.
Placebo Comparator: 3
20 subjects to receive normal saline.
- Safety (including all causes of mortality) in the test IVIg (Omr-IgG-am™) group versus the 2 placebo groups, as defined by the total number of serious adverse events regardless of relatedness to study drug administration. [ Time Frame: Duration of study. ]
- Pharmacokinetics of specific anti-WNV antibodies as measured by ELISA and PRNT methods. [ Time Frame: Baseline (pre-dose) blood sample collected immediately prior to the beginning of the infusion. After the infusion, additional blood samples collected at 1 hr, 6 hr, 12 hr, 24 hr, 72 hr, and then at Day 5, Day 7, Day 14, Day 30, Day 60 and Day 90. ]
- Proportion of patients returning to pre-morbid baseline at 3 months, between treated and untreated groups of patients with WNV infection, as assessed by two scoring systems the Barthel Index and the MRS. [ Time Frame: At 3 months. ]
- Improvement as compared to subject's own worst (of any earlier) evaluation, for each subject as defined by the combined results of the 4 neurological functional tests. [ Time Frame: At 3 months. ]
- Mortality alone among confirmed WNV patients. [ Time Frame: At 3 months. ]
- Combined morbidity and mortality in treatment versus placebo groups for all (including those without WNV infection) subjects by intention to treat analysis. [ Time Frame: At 3 months. ]
- Combined primary endpoint of mortality and morbidity among confirmed WNV patients as assessed by four scoring systems: the Barthel Index, the MRS, the GOS and the 3MS, in the experimental treatment group versus the control group. [ Time Frame: At 3 months. ]
