High Hopes for Ketamine Depression Treatments

Plus, two other glutamate-based agents are in development for depression by Roche (RHHBY). And Johnson & Johnson (JNJ - Get Report), has esketamine, an intranasal form of the drug, in phase II trials. Nasal delivery would be a big winner.

One would think it would be hard to make money off of a drug like ketamine that has been around for almost 50 years. But with the dearth of depression treatments that actually work and with drug companies shying away from developing new drugs that treat psychiatric  disorders, ketamine, with its long history as an anesthetic, is getting a hard look.

Research and current real-life, off-label use of the drug shows that most depressed patients definitely feel effects when ketamine starts flowing into their veins. Right away. This in contrast to the standard antidepressant pill, which can take four to six weeks to work, and even then, not often all that great.

Here's how treatment works: A small dose is infused into a patient over 40 minutes. After about 10 minutes, patients report feeling as if the weight of their depression is being lifted so much so that they are levitating, flying, floating above the bed.

People come down from the intense high in about two hours, but the antidepressant effects stick around long after the relatively short half-life of two to four hours -- as long as four weeks, in some published trials. All effects seem to wear off after a while, though, and patients likely have to come back for new infusions every few weeks. At say, $500 or more a pop. Nice repeat business.

One start-up company, Ketanetics, is creating a network of physicians who offer their "ketamine-based treatment algorithm" to help "physicians quickly incorporate ketamine-infusion therapy into their practices." The Newburyport, Mass.-based company is co-founded by well-known psychiatrist Keith Ablow, who has appeared as an expert on many national television programs, such as Dr. Oz, Oprah and the O'Reilly Factor.

If ketamine is a success, it may encourage scientists to look outside the lab, and into dance clubs, veterinary clinics -- and even the streets -- for the next blockbuster drug.
