Arms and Interventions

Arm Intervention/Treatment
Experimental: A

MEDI8111

Drug: MEDI8111
MEDI8111 lyophilisate for solution for infusion

Placebo Comparator: B

Placebo for MEDI8111

Other: Placebo
Placebo for MEDI8111 saline solution for infusion

Outcome Measures

Primary Outcome Measures

  1. Description of the Safety Profile in Terms of Adverse Events (AE),Vital Signs, ECG, Lab Variables, Immunogenicity and Physical Examination [From screening and up to the lab follow-up visit (Day 29)]

Secondary Outcome Measures

  1. Change From Baseline Endogenous Thrombin Potential (ETP) [Predose and Days 1-5]

    For the baseline variables and adverse events the two placebo arms (placebo dose 1 and placebo dose 2) are recorded as one. For the secondary outcome measures the two placebo arms are recorded separately.

  2. Change From Baseline Factor II Concentrations by ECL Assay [Predose and 1-8 hours]

  3. Change From Baseline Factor II Concentrations by Clot Assay [Predose and 1-8 hours]

  4. Change From Baseline D-dimer Concentration [predose and 1-8 hours]

Participant Flow

Recruitment Details Male healthy volunteers recruited by advertisement during the period October 2013 - October 2014
Pre-assignment Detail The study was prematurely terminated after 2 cohorts as dose escalation stopping criteria (PD thresholds) were reached and it was judged to be of limited value to expose more healthy subjects. Cohort 1: 2 placebo + 4 MEDI8111 dose 1. Cohort 2: 2 placebo + 4 MEDI8111 dose 2.
