The synthesis of suramin was an extension of Paul Ehrlichs pioneering work that showed that certain chemical dyes were concentrated in microbial parasites like the trypanosomes that cause African sleeping sickness. The primary endpoint of the study was the change between baseline and Week 14 in the Aberrant Behavior Checklist (ABC) composite score of core symptoms (ABC Core) including ABC-II (lethargy/social withdrawal), ABC-III (stereotypy) and ABC-V (inappropriate speech).
