简要总结
This is a prospective, single-center, randomized, double-blind, placebo-controlled, single-ascending dose (SAD) phase 1 study to evaluate the safety, tolerability and pharmacokinetics of FBL-MTX in healthy male and female subjects.
详细描述
The product FBL-MTX consists of Methotrexate (MTX) encapsulating liposomes functionalized with a folate peptide (SP-DS3), which targets activated macrophages of rheumatoid arthritis (RA).
This is a prospective, single-center, randomized, double-blind, placebo-controlled, single-ascending dose (SAD) phase 1 study in healthy subjects.
This study is planned to investigate up to 4 dose levels of FBL-MTX. Each dose level will consist of 8 healthy male and female subjects (ratio 1:1, male:female) to have 6 subjects being administered FBL-MTX and 2 subjects being administered placebo (ratio 3:1, active:placebo).
The study is designed to meet the following objectives:
- Primary: To evaluate the safety and tolerability of FBL-MTX following single-ascending intravenous doses to healthy male and female subjects.
- Secondary: To investigate the PK of FBL-MTX following single-ascending intravenous doses to healthy male and female subjects.
