Official Title: A Phase 1, Placebo-Controlled, Randomized Study To Assess The Safety, Tolerability, Pharmacokinetics, And Pharmacodynamics Following Single, Escalating, Intravenous Doses Of RN316 (PF-04950615) In Healthy Adult Subjects

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Safety and tolerability of single, escalating, intravenous infusions of RN316 administered to healthy adult subjects [ Time Frame: Entire duration of study ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • pharmacokinetics of RN316 in plasma after administration of single, escalating, intravenous infusions of RN316 to healthy adult subjects [ Time Frame: Entire duration of study ] [ Designated as safety issue: Yes ]
  • pharmacodynamic effect (lipid-lowering) of single, escalating, intravenous doses of RN316 administered to healthy adult subjects [ Time Frame: Entire duration of study ] [ Designated as safety issue: No ]
  • single dose immunogenicity [ Time Frame: Entire duration of study ] [ Designated as safety issue: Yes ]
