简要总结

详细描述
A Phase 1, randomized, double-blind, placebo-controlled dose escalation trial of four dose cohorts of 10 subjects (1: 10mg, 2: 25mg, 3: 50mg, 4: 100mg). Dose escalation will not occur until safety data through Day 8 is reviewed by the Safety Review Committee (SRC). The study will consist of a twenty-eight day screening period, 12-hour clinic stay, and 120-day (Cohorts 1-3) or 180-day (Cohort 4) outpatient follow-up. The primary objective of this study is to assess the safety and tolerability of escalating doses of G03-52-01 administered intramuscularly (IM) in healthy adult subjects. The secondary objectives are to evaluate the pharmacokinetics (PK) and immunogenicity of escalating IM doses of G03-52-01.

- •The hemoglobin, platelet count, white blood cell count and absolute neutrophil count are not below the LLN and ≤ULN x 10%
- •Abnormalities in mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), mean platelet volume (MPV), and nucleated red blood cell count (NRBC CT), which are included in a complete blood count with differential, will not be exclusions.
- •The urine dipstick results on protein, glucose and blood are negative or trace
- •Note: Menstruating females failing inclusion criteria due to a positive blood on urine dipstick may be retested following cessation of menses.
- •Note: When a urine dipstick is more than trace positive for blood (whether a menstruating female or other subjects), that subject would not be excluded if the urine microscopic exam shows <5 rbcs/hpf.

- •The urine drug screen is negative
- •Breathalyzer test is negative
- •Available for follow-up for the duration of the study
- •Agrees not to participate in vigorous activity 72 hours prior to dosing through day 15 post dosing
