简要总结
DLBS1033 is bioactive protein fraction which extracted from Lumbricus rubellus earthworm. This earthworm comes from Pengalengan, West Java, Indonesia. DLBS1033 possesses 8 major proteins with molecular weight below 100 kDa, so its named as Lumbricus Low Molecular weight Proteins (LLP). This enzyme can be transported to the bloodstream via intestinal epitel. As a drug that consists of serin protease enzyme, suspected that the mechanism of action of lumbrokinase, especially as fibrinolytic and antithrombotic. One study of DLBS1033 concluded that plasmin-antiplasmin (PAP) complex is a sensitive parameter for evaluating fibrinolytic effect of this drug. But, until now there is no clinical study that evaluate pharmacokinetic of this drug. As a pilot study, the aim of this study is to evaluate biological half life of DLBS1033.

研究组 & 干预措施
single dose DLBS1033
Before taking the drug, blood samples will be collected from subject to assess PAP complex level, serum creatinine, SGOT, SGPT, PT and aPTT. After that, subjects will instructed to take three tablets enteric coated of DLBS1033 in front of investigator. After take the medicine blood sample will be collected on 30 minute, 60 minute, 90 minute, 2 hour, 3 hour, 4 hour, 6 hour, 8 hour, 10 hour, 12 hour, and 24 hour to evaluate serial PAP complex. Subjects will undergo a clinical assessment including vital signs and the presence of adverse events at the time of blood sampling. On this trial, subjects are only permitted to eat food from investigator.

steady state of DLBS1033
On day 1 blood samples will be collected to assess PAP complex level, serum creatinine, SGOT, SGPT, PT and aPTT. After that, subjects will instructed to take one tablet of DLBS1033 in front of investigator. Study drug packages (that consist of 8 tablets) will dispense to the subjects at day-1 and instructed to take the drug 3 times daily 30 minutes before meals. Subjects also will instructed to record any adverse events and concomitant medication prescribed in diary card. Subjects have to take the drug on 3 days (day 1, 2, and 3). On day 4, blood sample will be collected on 0 minutes, 30 minute, 60 minute, 90 minute, 2 hour, 3 hour, 4 hour, 6 hour, 8 hour, 10 hour, 12 hour, and 24 hour to evaluate serial PAP complex. Subjects will undergo a clinical assessment including vital signs and the presence of adverse events at the time of blood sampling. On this trial, subjects are only permitted to eat food from investigator.
