Randomized, Double-Blind Phase 1 Safety and Tolerability Study of Pafuramidine Maleate (DB289) in Healthy Subjects

This is a phase 1 study to establish the safety and tolerability profile of pafuramidine maleate 100 mg BID administered orally for 14 days to healthy subjects

Study Overview

• Status: Terminated
• Conditions: Healthy
• Intervention / Treatment: Drug: Placebo; Drug: pafuramidine maleate
