Outcome Measures
Primary Outcome Measures
- 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
- 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.
- Change From Baseline Factor II Concentrations by ECL Assay [Predose and 1-8 hours]
- Change From Baseline Factor II Concentrations by Clot Assay [Predose and 1-8 hours]
- Change From Baseline D-dimer Concentration [predose and 1-8 hours]
Eligibility Criteria
Criteria
Inclusion Criteria:
- Provision of signed and dated, written informed consent prior to any study specific procedures, Healthy male subjects aged 18-40 years with suitable veins for cannulation or repeated venepuncture, Have a body mass index (BMI) between 18 and 30 kg/m2 inclusive and weight at least 50 kg an no more than 100 kg inclusive, Male subjects should be willing to avoid fathering a child by either true abstinence or the use of two effective means of contraception from the day of dosing until 3 months after dosing with the IP. They should also be willing to use barrier methods from the day of dosing until 3 months after dosing.
Exclusion Criteria:
- Prothrombotic mutation such as factor V Leiden, or deficiencies of protein C, protein S, prothrombin, antithrombin or APC, Antibodies to coagulation FII, History or family history of venous or arterial thromboembolic event, and/or myocardial infarction before age of 50 years, ETP level at baseline >2000nM/min, FII level (by clot) at screening and/or at baseline outside 50-250% of the normal range

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. |
