A drug discovered more than 100 years ago may hold the key to combating autism symptoms, according to a study.

Researcher Dr Robert Naviaux of the San Diego School of Medicine gave suramin, a drug first developed in 1916, to 10 autistic boys between the ages of five and 14, and noted transformative results.

"After the single dose, it was almost like a roadblock had been released," he said. "If the future studies show that there's continued health benefits, this could be a game-changer for families with autism."

The study, which has been published in the Annals of Clinical and Translational Neurology, saw five of the participants receive suramin, while the remainder were given placebos. Included in the group were four non-verbal children – two six year olds and two 14 year olds.

"The six year old and the 14 year old who received suramin said the first sentences of their lives about one week after the single suramin infusion," Naviaux told the UC San Diego Health website. "This did not happen in any of the children given the placebo."

    The most frequent adverse reactions are...

    Not even going to bother quoting it, but wow its quite a list. And the two month half life means if you get "changes or loss of vision" or whatever it takes months to get even a little better.

    Intramuscular and subcutaneous administration could result in ... necrosis.

    Damn... screw up the injection and the kids arm literally rots off of them. Try not to do that.

    Suramin ... has a half-life of 41–78 days

    temporarily reversed symptoms

    OK so at least you get like four treatments per year, not daily or something.

    Suramin does not distribute well into cerebral spinal fluid and its concentration in the tissues is equivalently lower than its concentration in the plasma.

    Yeah thats not pointing to a neurological cause of autism. Although lower conc does not mean zero.

    Suramin is not extensively metabolized and about 80% is eliminated via the kidneys.

    Fits in with the pharmacokinetic widely varying rate, drink a lot of water pee out in 40 days what a dehydrated dude would keep for 80 days.

    It sounds biochemistry scary as hell. Which makes sense, lots of Autism money to go around and eventually the chemists are going to scare up something as terrifying as chemotherapy level substances that kill the autism just a little worst than they kill the patient.

    doi/10.1002/acn3.424 [wiley.com] on toxity:

    The low dose of suramin used in this study produced blood levels of 1.5–15 μmol/L for 6 weeks. Previous studies have never examined the side-effect profile of suramin in this low-dose range. The side-effect profile of high-dose suramin (150–270 μmol/L) is known from cancer chemotherapy studies.[32] The side-effect profile from medium-dose suramin (50–100 μmol/L) is known from African sleeping sickness studies.[46] However, the side-effect profile of low-dose suramin (5–15 μmol/L) used for antipurinergic therapy (APT) in autism is unknown. Low-dose suramin was found to be safe in five children with ASD, ages 5–14 years, in this study.

    As for greed:

    Conflict of Interest

    RKN has filed a provisional patent application related to antipurinergic therapy of autism and related disorders and is a scientific advisory board member for the Autism Research Institute and the Open Medicine Foundation. EVC is a DSMB member for Cempra Pharmaceuticals and The Medicines Company, and a consultant for Alexion. SG is co-owner of MitoMedical. The other authors declare no conflicts of interest.

      Oooh interesting. Of course treatment for ASD would seem to be weekly for life so the long term low dose will also be interesting to study. Hopefully a tolerance doesn't build up.

        I'll suspect there's a difference between people that have autism and asperger. In that people with autism really do have issues that blocks them from being happy. And a medicine like this might unlock certain regions of the brain. What to watch out for is people that are so determined to make these persons an image of their self and their preferences that they will are willing to seriously hurt the person they think they help but in reality will just make things worse.

        Before this can really be evaluated a larger trial will most likely be needed.

          I suspect asperger are high IQ autistic who are able to cope by using their advanced intelligence to overcome some of their issues.

            Interesting. As for my opinion, I suspect Jesus touches certain minds and Satan touches others. We should discuss on TV - remember it doesn't cost anything to pray to Jesus.

    From the paper:

    The terminal half-life was 14.7 ± 0.7 days. A self-limited, asymptomatic rash was seen, but there were no serious adverse events

    The dose makes the poison.
