Primary Outcome Measures:
  • Evaluate safety parameters in single-ascending doses of Tβ4(42 mg, 140 mg, 420 mg or 1,260 mg per dose) administered intravenously to healthy volunteers, such as ECG, vital signs,lab tests, etc. [ Time Frame: one day ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Evaluate pharmacokinetic parameters in single-ascending doses of Tβ4(42 mg, 140 mg, 420 mg or 1,260 mg per dose) administered intravenously to healthy volunteers [ Time Frame: one day ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: 2

Thymosin Beta 4

A single bolus injections of ascending doses of 42 mg, 140 mg, 420 mg or 1,260 QD

Drug: thymosin beta 4
Single bolus injections of ascending doses of 42 mg, 140 mg, 420 mg or 1,260 of thymosin beta 4
Placebo Comparator: 1
Placebo A single bolus injection of 0.0 mg of thymosin beta 4 QD
Other: Placebo
Single bolus injections of ascending doses of 0 mg of thymosin beta 4

Detailed Description:

The cardio-protective effect of Tβ4 treatment was shown in a permanently ligated mouse model.The authors demonstrated that systemic Tβ4 treatment (intraperitoneal, intracardiac, or i.p. plus intracardiac) every third day enhanced early myocyte survival and significantly improved cardiac function. Several weeks after the heart attack, it was evident that mice treated with Tβ4 had less muscle damage and stronger hearts compared with mice treated with placebo. Specifically, Tβ4 treatment significantly improved fractional shortening by about 60% and ejection fraction by about 100% and myocardial salvage by about 53% when compared with controls.
