Psy­che­delics have ex­pe­ri­enced a re­nais­sance in re­cent years amid a tor­rent of pre­clin­i­cal and clin­i­cal re­search sug­gest­ing it might pro­vide a path to treat mood dis­or­ders con­ven­tion­al reme­dies have on­ly scraped at. Now a pre­clin­i­cal tri­al from a young biotech sug­gests at least one psy­che­del­ic com­pound has ef­fects be­yond the mind, and — if you be­lieve the still very, very ear­ly hype — could pro­vide the first sin­gle rem­e­dy for some of the main com­pli­ca­tions of obe­si­ty.

A study in mice fund­ed by Eleu­sis and pub­lished in Sci­en­tif­ic Re­ports found a long-known drug called (R)-DOI could be used to treat car­dio­vas­cu­lar dis­ease, re­duc­ing in­flam­ma­tion in the aor­ta, de­creas­ing over­all and HDL cho­les­terol lev­els, and po­ten­tial­ly curb­ing di­a­betes by in­creas­ing glu­cose tol­er­ance.

Lead au­thor Charles Nichols says di­a­betes and high cho­les­terol, though of­ten re­sults of the same un­der­ly­ing con­di­tion, re­quire sep­a­rate drugs and a re­strict­ed di­et.

“This mod­el that treats car­dio­vas­cu­lar dis­ease and meta­bol­ic dis­ease — it’s all-en­com­pass­ing,” Nichols, a pro­fes­sor of phar­ma­col­o­gy at LSU, told End­points News. “Trans­lat­ed in­to the clin­ic in hu­mans, it would be as if some­one was obese, had di­a­betes, had high cho­les­terol, and was able to take a low dose of this drug at a sub-be­hav­ioral lev­el and re­al­ly treat sev­er­al dif­fer­ent as­pects of the com­pli­ca­tions of be­ing obese.”

They’re bold words, though al­most mut­ed in a psy­che­del­ic field brim­ming with hype. Re­searchers have called the re­sults of some psy­chi­atric stud­ies “mind-blow­ing” as clin­i­cal tri­als hint at the pow­er of psilo­cy­bin (the chem­i­cal in mag­ic mush­rooms) to al­le­vi­ate de­pres­sion and MD­MA to re­lieve PTSD.

The no­tion that the same class of drugs might have oth­er phys­i­o­log­i­cal and specif­i­cal­ly an­ti-in­flam­ma­to­ry ef­fects is new­er. Nichols, the son of long­time psy­che­del­ic re­search pro­po­nent David Nichols, un­der­stands the rhetoric can get rosy but points out that the tri­al was tar­get­ed. They test­ed DOI in oth­er types of tis­sue and when it had lit­tle ef­fect, fo­cused on vas­cu­lar in­di­ca­tions.

“This is not a com­plete panacea,” said Nichols, who ear­li­er tout­ed his an­i­mal stud­ies in­di­cat­ing DOI’s po­ten­tial in asth­ma.

Nichols dis­cov­ered that sero­tonin 5-HT_2A re­cep­tor ag­o­nists, fol­low­ing a well-un­der­stood path­way psy­che­delics act on, can re­duce in­flam­ma­tion by ac­ci­dent in his LSU lab in 2008. Lat­er, he got a cold call from Shlo­mi Raz, a for­mer Wall Street ex­ec­u­tive who went on to get a mas­ter’s in psy­chol­o­gy at NYU.

Shlo­mi Raz

Eleu­sis launched in 2013 with a mis­sion, Raz told End­points, of ex­plor­ing the broad pos­si­bil­i­ties for these ag­o­nists, with their work so far rang­ing from a tri­al on the ef­fects of ‘mi­cro-dos­ing’ LSD on time per­cep­tion to fil­ing a patent for the treat­ment of Alzheimer’s with LSD. Nichols has pub­lished sev­er­al pre­vi­ous stud­ies on psy­che­delics and an­ti-in­flam­ma­to­ries, but this was no­table in its abil­i­ty to on­ramp in­to clin­i­cal tri­als.

Raz be­lieves what is com­mon­ly called psy­che­delics have a broad ar­ray of im­pacts be­yond their “psy­che­del­ic” func­tion. He says he has peer-re­viewed re­search com­ing soon that will help bol­ster that claim, and that the cen­tral ques­tion is how to un­lock those ef­fects with­out trig­ger­ing the psy­cho­log­i­cal im­pact.

“If you think of it as an ice­berg,” Raz said, “maybe the tip of the ice­berg is the psy­chi­atrics and the part be­low the sur­face is not psy­chi­atric.”

The vas­cu­lar study showed phys­i­o­log­i­cal with­out any psy­cho­log­i­cal ef­fects (mice giv­en a psy­che­del­ic can some­times show be­hav­ior con­sis­tent with psy­chosis). The re­searchers fat­tened up mice on the “West­ern di­et” for four months and at in­ter­vals ad­min­is­tered DOI to one group and saline to a con­trol.

They found that vas­cu­lar in­flam­ma­tion was low­er in the DOI, as they an­tic­i­pat­ed. They hadn’t an­tic­i­pat­ed that cho­les­terol would be down and glu­cose tol­er­ance up, and they’re still not sure why.

Nichols, though, said the study was trans­lat­able to a clin­i­cal tri­al, and he was hope­ful there would be a drug with­in 10 to 20 years. Reg­u­la­tion, more than the sci­ence, was the bar­ri­er. Raz was mum about what’s next, both in terms of oth­er ap­pli­ca­tions and in busi­ness mod­el, but he left one clue:

“I can tell you it’s not a pill,” he said, “at first.”

Medical animation has in recent years become an increasingly important tool for conveying niche information to a varied audience, particularly to those audiences without expertise in the specialist area. Science programmes today, for example, have moved from the piece-to-camera of the university professor explaining how a complex disease mechanism works, to actually showing the viewer first-hand what it might look like to shrink ourselves down to the size of an ant’s foot, and travel inside the human body to witness these processes in action. Effectively communicating a complex disease pathophysiology, or the novel mechanism of action of a new drug, can be complex. This is especially difficult when the audience domain knowledge is limited or non-existent. Medical animation can help with this communication challenge in several ways.
Improved accessibility to visualisation
Visualisation is a core component of our ability to understand a concept. Ask 10 people to visualise an apple, and each will come up with a slightly different image, some apples smaller than others, some more round, some with bites taken. Acceptable, you say, we can move on to the next part of the story. Now ask 10 people to visualise how HIV’s capsid protein gets arranged into the hexamers and pentamers that form the viral capsid that holds HIV’s genetic material. This request may pose a challenge even to someone with some virology knowledge, and it is that inability to effectively visualise what is going on that holds us back from fully understanding the rest of the story. So how does medical animation help us to overcome this visualisation challenge?

As a potentially powerful flu season looms, so does a big test for Roche and its new flu drug, Xofluza. The Swiss giant just got a small boost in advance of that test as the FDA expanded Xofluza’s indication to include patients at high risk of developing flu-related complications.

Xofluza (baloxavir marboxil) was approved last October in the US, the first landmark flu drug approval in 20 years and a much-needed green light for a company that had watched its leading flu drug Tamiflu get eaten alive by generics. Like its predecessor, the pill offered a reduction in flu symptoms but not a cure.

The first-ever Ebola vaccine is on the precipice of approval after the European Medicine’s Agency (EMA) backed the Merck product in this week’s roster of recommendations.

The drugmaker $MRK began developing the vaccine, christened Ervebo, during the West African outbreak that occurred between 2014 and 2016, killing more than 11,000.

The current outbreak in the Democratic Republic of Congo (DRC) has shown case fatality rates of approximately 67%, the agency estimated. Earlier this year, the WHO declared the outbreak — which so far has infected more than 3,000 people — a public health emergency of international concern.
