Positive urine drug screening in screening stage. Suramin was shown to be safe and effective in three preclinical models of ASD9-11 and a small human clinical trial1 in peer-reviewed papers published between 2013-2017. The Naviaux Lab discovered that the unique properties of suramin made it the first in a new class of drugs that could be used to test the cell danger response (CDR) hypothesis for the origin and treatment of autism spectrum disorder (ASD). The small clinical trial involved 10 boys, including five who received a placebo and did not show improvement.
