A RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, ASCENDING DOSE STUDY TO EVALUATE PLASMA GELSOLIN IN HEALTHY VOLUNTEERS
Study Details
Study Description
Brief Summary
Study BTI-101 is a Phase 1, randomized, double-blind, placebo-controlled, dose escalation, parallel design study to evaluate the safety, tolerability, and pharmacokinetics of IV rhu-pGSN or saline placebo administered as 5 doses each of 6, 12, 18, or 24 mg/kg of body weight. Each of 4 dosing cohorts will include 8 subjects randomized 3:1 rhu-pGSN:placebo (6 rhu-pGSN subjects:2 placebo subjects). Subjects will be healthy adult volunteers 18-55 years of age.

Phase 1 |
Detailed Description
Doses will be administered at 0 hours (Day 1), 12 hours (Day 1), 36 hours (Day 2), 60 hours (Day 3), and 84 hours (Day 4). Subjects will be kept in-house until after the last blood sample is taken on Day 5. Subjects will return for follow-up 7 days after the initiation of therapy (Day 8) and on Day 28 for the End-of-Study (EOS) Visit. After each cohort has completed the Day 8 visit, review of the safety results (including labs) will be conducted (and unblinded where appropriate) before the initiation of the next higher dose cohort.
To assess safety and tolerability, subjects will undergo physical examinations (including vital sign measurements), adverse event (AE) assessments, concomitant medication assessments, and safety laboratory testing. Blood samples will be collected for analysis of pGSN levels and antibodies against pGSN.
