There are no FDA approved treatments for the core symptoms of ASD and no FDA approved treatments at all for FXTAS. Further development of suramin was passed from Dr. Naviauxs university research lab to the private sector. Subjects were diagnosed with ASD by DSM-5 criteria and severity was measured by the Autism Diagnostic Observation Schedule. PAX-101, an antipurinergic agent delivered as an IV infusion, has also been shown to have significant anti-inflammatory properties based on non-purine receptor pathways in multiple disease models. At Week 14, patients treated with PAX-101 also demonstrated a mean improvement from baseline in the CGI-I overall symptom severity score of 0.9 points versus 0.4 on placebo, representing a clinically meaningful change from baseline.

A total of 36 subjects are divided into three dosage groups: 10mg/kg, 15mg/kg and 20mg/kg, in which 20mg/kg is the conventional dosage per international pharmacopoeias for established indications of suramin sodium. The mechanism of the drug's action in a condition like ASD is not fully understood and has been postulated to act through purinergic receptor blockade to reverse the effects of mitochondrial dysfunction, but also has been postulated to act through the reduction of neuroinflammation in this population. The study population included a patient population with diverse ethnicity and the mean age for the study population was 8.43 ( SD 3.24). The safety and tolerability of suramin has been well characterized in the treatment of other illnesses. It is our hope that each success will lay the groundwork for more successes, and soon there will be a drug, device, and therapeutic Renaissance that will create dozens of new tools that doctors can use to regulate the cell danger response and help patients heal.
