Ketamine could become an approved treatment for depression in the UK soon:

Ketamine has 'fast-acting benefits' for depression

Ketamine has "shown promise" in the rapid treatment of major depression and suicidal thoughts, a US study says. Ketamine has a reputation as a party drug but is licensed as an anaesthetic. The study found use of the drug via a nasal spray led to "significant" improvements in depressive symptoms in the first 24 hours. The Royal College of Psychiatrists said it was a "significant" study that brought the drug "a step closer to being prescribed on the NHS".

The report by researchers from Janssen Research and Development, a Johnson and Johnson company, and Yale School of Medicine, is the first study into ketamine as a treatment for depression that has been done by a drug company.

[...] The study found those using esketamine had a much greater improvement in depression symptoms at all points over the first four weeks of treatment. However, at 25 days the effects had levelled out. The study's authors suggest it could offer an effective rapid treatment for people severely depressed and at imminent risk of suicide and could help in the initial stages of treatment, as most anti-depressants take four to six weeks to become fully effective.

FDA Designates MDMA as a "Breakthrough Therapy" for PTSD; Approves Phase 3 Trials 28 comments

The U.S. Food and Drug Administration has given its approval for Phase 3 trials to treat participants with PTSD using MDMA ("ecstacy"):

The non-profit Multidisciplinary Association for Psychedelic Studies (MAPS) today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to MDMA for the treatment of posttraumatic stress disorder (PTSD). MAPS and the FDA have also reached agreement under the Special Protocol Assessment Process (SPA) for the design of two upcoming Phase 3 trials (MAPP1 and MAPP2) of MDMA-assisted psychotherapy for patients with severe PTSD.

MDMA-assisted psychotherapy is a novel treatment package that combines psychotherapeutic techniques with three administrations of MDMA as a pharmacological adjunct. By granting Breakthrough Therapy Designation, the FDA has agreed that this treatment may have a meaningful advantage and greater compliance over available medications for PTSD.

The first Phase 3 trial (MAPP1), "A Randomized, Double-Blind, Placebo-Controlled, Multi-Site Phase 3 Study of the Efficacy and Safety of Manualized MDMA-Assisted Psychotherapy for the Treatment of Severe Posttraumatic Stress Disorder," will begin enrolling subjects in Spring 2018, after the completion of an open-label lead-in training study at Phase 3 sites starting this fall.

[...] The Phase 3 trials will assess the efficacy and safety of MDMA-assisted psychotherapy in 200-300 participants with PTSD, aged 18 and older, at sites in the U.S., Canada, and Israel. Participants will be randomized to receive three day-long sessions of either MDMA or placebo in conjunction with psychotherapy over a 12-week treatment period, along with 12 associated 90-minute non-drug preparatory and integration sessions. The primary endpoint will be the Clinician Administered PTSD Scale (CAPS-5), as assessed by a blinded pool of independent raters.

In MAPS' completed Phase 2 trials with 107 participants, 61% no longer qualified for PTSD after three sessions of MDMA-assisted psychotherapy two months following treatment. At the 12-month follow-up, 68% no longer had PTSD. All Phase 2 participants had chronic, treatment-resistant PTSD, and had suffered from PTSD for an average of 17.8 years.

Also at ScienceAlert, the Washington Post, and Science Magazine:

Since 2012, FDA has designated close to 200 drugs as breakthrough therapies, a status that indicates there's preliminary evidence that an intervention offers a substantial improvement over other options for a serious health condition. The agency aims to help develop and review these treatments faster than other candidate drugs.

Study Suggests Psilocybin "Resets" the Brains of Depressed People 58 comments

An fMRI study has found evidence of a reduction in depressive symptoms after treatment with psilocybin:

A hallucinogen found in magic mushrooms can "reset" the brains of people with untreatable depression, raising hopes of a future treatment, scans suggest.

The small study gave 19 patients a single dose of the psychedelic ingredient psilocybin. Half of patients ceased to be depressed and experienced changes in their brain activity that lasted about five weeks.

However, the team at Imperial College London says people should not self-medicate.

There has been a series of small studies suggesting psilocybin could have a role in depression by acting as a "lubricant for the mind" that allows people to escape a cycle of depressive symptoms. But the precise impact it might be having on brain activity was not known.

Ketamine Reduces Suicidal Thoughts in Depressed Patients 34 comments

Study: Suicidal Thoughts Rapidly Reduced with Ketamine

Ketamine was significantly more effective than a commonly used sedative in reducing suicidal thoughts in depressed patients, according to researchers at Columbia University Medical Center (CUMC). They also found that ketamine's anti-suicidal effects occurred within hours after its administration.

The findings were published online last week in the American Journal of Psychiatry.

Ketamine for Rapid Reduction of Suicidal Thoughts in Major Depression: A Midazolam-Controlled Randomized Clinical Trial (DOI: 10.1176/appi.ajp.2017.17060647) (DX)

The reduction in SSI score at day 1 was 4.96 points greater for the ketamine group compared with the midazolam group (95% CI=2.33, 7.59; Cohen's d=0.75). The proportion of responders (defined as having a reduction ≥50% in SSI score) at day 1 was 55% for the ketamine group and 30% for the midazolam group (odds ratio=2.85, 95% CI=1.14, 7.15; number needed to treat=4.0). Improvement in the Profile of Mood States depression subscale was greater at day 1 for the ketamine group compared with the midazolam group (estimate=7.65, 95% CI=1.36, 13.94), and this effect mediated 33.6% of ketamine's effect on SSI score. Side effects were short-lived, and clinical improvement was maintained for up to 6 weeks with additional optimized standard pharmacotherapy in an uncontrolled follow-up.

Wikipedia's entry on midazolam notes:

Midazolam, marketed under the trade name Versed, among others, is a medication used for anesthesia, procedural sedation, trouble sleeping, and severe agitation. It works by inducing sleepiness, decreasing anxiety, and causing a loss of ability to create new memories. It is also useful for the treatment of seizures

Studies Identify How Ketamine Can Reverse Symptoms of Depression 26 comments

New studies zero in on roots of depression and why ketamine reverses it

[There's] been significant progress in unravelling the confusion over ketamine, with researchers identifying a ketamine derivative that tackles depression with far fewer side effects. And this week, a team of researchers at China's Zhejiang University announced that they've figured out where in the brain ketamine acts when it blocks depression, a finding that gives us significant insights into the biology of the disorder.

The new studies rely on the work of a number of other labs, which have identified a specific structure deep in the brain that's associated with depression. Called the lateral habenula, it's been associated with a variety of activities, the most relevant of which seems to be the processing of unpleasant outcomes and punishment. Electrodes implanted there have been used to relieve depression in at least one instance.

To test whether this might be the site of ketamine's activity, one team of researchers infused the drug directly into the lateral habenula of rats with depression-like symptoms; it blocked them. So did a separate chemical that inhibits the same proteins that ketamine acts on. Tracking the activity in the area, the researchers were able to show that there are bursts of activity in rats with symptoms of depression that are absent in healthy rats. The drugs that blocked depression suppressed these bursts.

Over Years, Depression Changes the Brain, new Study Shows 42 comments

Research shows that longstanding depression alters the brain -- treatment may require different approaches depending on not just the severity of the depression but also on its longevity:

Is clinical depression always the same illness, or does it change over time?

New brain imaging research from the Centre for Addiction and Mental Health (CAMH) shows that the brain alters after years of persistent depression, suggesting the need to change how we think about depression as it progresses.

The study, led by senior author Dr. Jeff Meyer of CAMH's Campbell Family Mental Health Research Institute, is published in The Lancet Psychiatry.

The research shows that people with longer periods of untreated depression, lasting more than a decade, had significantly more brain inflammation compared to those who had less than 10 years of untreated depression. In an earlier study, Dr. Meyer's team discovered the first definitive evidence of inflammation in the brain in clinical depression.

This study provides the first biological evidence for large brain changes in long-lasting depression, suggesting that it is a different stage of illness that needs different therapeutics - the same perspective taken for early and later stages of Alzheimer's disease, he says.

"Greater inflammation in the brain is a common response with degenerative brain diseases as they progress, such as with Alzheimer's disease and Parkinson´s disease," says Dr. Meyer, who also holds Canada Research Chair in the Neurochemistry of Major Depression. While depression is not considered a degenerative brain disease, the change in inflammation shows that, for those in whom depression persists, it may be progressive and not a static condition.

4/20: The Mary Jane Majority 56 comments

U.S. Senate Minority Leader Chuck Schumer (D-NY) has come out in support of federal cannabis decriminalization, just in time for 4/20:

The Minority Leader of the Senate is making it official the day before 4/20: He's down with legal weed. In an exclusive interview with VICE News, Sen. Chuck Schumer (D-NY) confirmed he is putting his name on legislation that he said is aimed at "decriminalizing" marijuana at the federal level. For Schumer, this is a shift. While he has backed medical marijuana and the rights of states to experiment with legal sales of pot, what he is proposing is a seismic shift in federal drug policy.

"Ultimately, it's the right thing to do. Freedom. If smoking marijuana doesn't hurt anybody else, why shouldn't we allow people to do it and not make it criminal?" Schumer said.

The legislation should be available within a week or so, and would remove cannabis (still listed as "Marihuana") from the Drug Enforcement Administration's list of Schedule I substances. States would then be free to regulate or continue to prohibit the plant. Cannabis advertising would be regulated as are alcohol and tobacco advertising. (Also at NPR, CNN, The Washington Post, and CNBC, as well as Reason taking a shot at Schumer for not doing it sooner.)

A majority of Americans support the legalization of cannabis, including, for the first time, a majority (51%) of Republicans, according to Gallup. Nine states and the District of Columbia have legalized cannabis for recreational use. 29 states, D.C., Guam, and Puerto Rico have legalized medical use of cannabis, and another 17 states have legalized the use of cannabidiol (CBD). Cannabis became available for recreational purposes in California on January 1.

Groundbreaking Ketamine-Derived Treatment for Depression Approved by the U.S. FDA 24 comments

Fast-Acting Depression Drug, Newly Approved, Could Help Millions

Of the 16 million American adults who live with depression, as many as one-quarter gain little or no benefit from available treatments, whether drugs or talk therapy. They represent perhaps the greatest unmet need in psychiatry. On Tuesday, the Food and Drug Administration approved a prescription treatment intended to help them, a fast-acting drug derived from an old and widely used anesthetic, ketamine.

The move heralds a shift from the Prozac era of antidepressant drugs. The newly approved treatment, called esketamine, is a nasal spray developed by Janssen Pharmaceuticals Inc., a branch of Johnson & Johnson, that will be marketed under the name Spravato. It contains an active portion of the ketamine molecule, whose antidepressant properties are not well understood yet. "Thank goodness we now have something with a different mechanism of action than previous antidepressants," said Dr. Erick Turner, a former F.D.A. reviewer and an associate professor of psychiatry at Oregon Health & Science University. "But I'm skeptical of the hype, because in this world it's like Lucy holding the football for Charlie Brown: Each time we get our hopes up, the football gets pulled away."

[...] Esketamine, like ketamine, has the potential for abuse, and both drugs can induce psychotic episodes in people who are at high risk for them. The safety monitoring will require doctors to find space for treated patients, which could present a logistical challenge, some psychiatrists said.

The wholesale cost for a course of treatment will be between $2,360 and $3,540, said Janssen, and experts said it will give the company a foothold in the $12 billion global antidepressant market, where most drugs now are generic.

[...] One question that will need to be answered is how well esketamine performs in comparison to intravenous ketamine.

      I know you are being slightly sarcastic with your post. That said, I want to ensure the real benefit of treating highly depressed people is highlighted. Bringing a highly depressed person back from the edge is a huge win; they don't have to get to "pure happy time", just enough so they can get some help and work on the overall depression they have. Discoveries like this will help many, many people and their families in the future.

        In veterinary anesthesia, ketamine is often used for its anesthetic and analgesic effects on cats,[216] dogs,[217] rabbits, rats, and other small animals.[218][219] It is highly used in induction and anesthetic maintenance in horses. It is an important part of the "rodent cocktail", a mixture of drugs used for anesthetizing rodents.[220] Veterinarians often use ketamine with sedative drugs to produce balanced anesthesia and analgesia, and as a constant-rate infusion to help prevent pain wind-up. Ketamine is used to manage pain among large animals, though it has less effect on bovines and off-topic downvoters.

    ...and for some reason they put me on ketamine. I have no idea why anyone would do that shit recreationally. I was in screaming agony and the ketamine did noting for that, but I just didn't give a crap - the ketamine saw to it that I had no emotional response to the pain, or to anything really. The head nurse said "we should take him off the ketamine" - I realised I was in screaming agony, so that when I was pulled off the ketamine I WOULD care. The thing is I just didn't care about ANYTHING, including telling her this... well... up until the ketamine wore off anyway. :)
