Study Details

Study Description

Brief Summary

Clinical Phase 1 study to investigate the pharmacokinetics and to assess the safety and tolerability of recAP after single and multiple intravenous doses in healthy Japanese subjects.

Condition or Disease Intervention/Treatment Phase
  • Biological: single 1-hour IV infusion of 0.8 mg/kg recAP
  • Biological: single 1-hour IV infusion of 1.6 mg/kg recAP
  • Biological: single 1-hour IV infusion of 3.2 mg/kg recAP
  • Biological: 1-hour infusions of 1.6 mg/kg recAP on Days 1, 2 and 3
  • Biological: Placebo
Phase 1

Detailed Description

This study is a randomized, double blind, parallel group, single-center trial, consisting of a single dose part and a multiple dose part in 32 healthy Japanese subjects. Since all these doses have been studied before and safety extensively evaluated in non-Japanese subjects and no ethnic sensitivity is expected, the groups can be dosed in parallel.

Part A will have 3 parallel groups of 8 male subjects with N=6 on active and N=2 on placebo per group. Following baseline assessments, a single dose of recAP will be administered by a one-hour infusion followed by samplings for pharmacokinetic evaluation and routine safety assessments.

Part B will have a single group of 8 male subjects with N=6 on active and N=2 on placebo. Following baseline assessments, recAP will be dosed on Days 1, 2 and 3 by one-hour infusions followed by samplings for pharmacokinetic evaluation and routine safety assessments.
