Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Basic Science
Official Title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Ascending Single and Multiple-Dose Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of SB1578 When Administered Orally to Healthy Adult Subjects With One Single-Dose Group Crossing Over to Assess Food Effect

Further study details as provided by S*BIO:

Primary Outcome Measures:
  • Assess number of participants with adverse events as a measure of safety and tolerability [ Time Frame: 312 hours postdose ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Assess pharmacokinetics to determine study drug half-life, maximum concentration time, elimination time, and area under the curve [ Time Frame: Predose to 312 hours postdose ] [ Designated as safety issue: No ]
  • Assess pharmacodynamics to determine study drug levels to signal pJAK2, pSTAT3, and pSTAT5 [ Time Frame: Predose, 6 and 24 hours postdose ] [ Designated as safety issue: No ]
  • Assess food effects on pharmacokinetics [ Time Frame: Predose to 312 hours postdose ] [ Designated as safety issue: No ]
  • Determine recommended dose [ Time Frame: March 2011 ] [ Designated as safety issue: Yes ]
