Primary Outcome Measures
NameTimeMethod
<br> The safety of BK-SE36 is assessed by the presence or absence of adverse events evaluated from test results, subjective/objective symptoms, laboratory data, blood pressure/pulse rate and body temperature.<br><br> Subjects were visited once a week. At every subjects' visit to the hospital, doctors did health interview for finding some symptoms and blood/serum examination and measurement of blood pressure etc were conducted at the time.<br>
Secondary Outcome Measures
NameTimeMethod
<br> Changes in the anti-SE36 protein antibody titre at each time point.<br><br> Subjects were visited once a week. At every subjects' visit to the hospital, doctors did health interview for finding some symptoms and blood/serum examination and measurement of blood pressure etc were conducted at the time.<br>
