Psy­che­del­ic re­search gains mo­men­tum, as ear­ly tri­al sug­gests mi­cro-dos­ing LSD is safe

Psy­che­delics have been long ne­glect­ed as the sub­ject of vig­or­ous sci­en­tif­ic re­search af­ter gov­ern­ments brand­ed them as il­le­gal he­do­nis­tic com­pounds with no ther­a­peu­tic po­ten­tial. But in re­cent years, de­spite tricky reg­u­la­tions, a resur­gence of in­ter­est from re­searchers has cul­mi­nat­ed in an FDA ap­proved ke­t­a­mine-de­rived de­pres­sion treat­ment, clin­i­cal tri­als test­ing the po­ten­tial of psilo­cy­bin in ‘mag­ic mush­rooms,’ and the set­ting up of a psy­che­del­ic re­search cen­ter at Johns Hop­kins.

The col­or­less, odor­less and taste­less drug, ly­ser­gic acid di­ethy­lamide (LSD) — or acid, as it is fond­ly known — is part of this re­search re­nais­sance. On Wednes­day, a small pri­vate­ly held com­pa­ny — Eleu­sis Ben­e­fit Cor­po­ra­tion — un­veiled da­ta from an ear­ly study in healthy old­er vol­un­teers that test­ed its mi­cro-dos­ing ap­proach with LSD. And if it all goes ac­cord­ing to plan — nev­er a sure thing in biotech — they’ve got plans to tar­get Alzheimer’s with the ap­proach.

Neilo­u­far Fam­i­ly

In the study, 48 vol­un­teers (mean age = 62.9 years) re­ceived ei­ther 5 μg, 10 μg, or 20 μg of LSD, or place­bo  — ad­min­is­tered in wa­ter — every four days in six ses­sions. Over­all, the LSD was well tol­er­at­ed, and the fre­quen­cy of ad­verse events was no high­er than the place­bo, the com­pa­ny said, while claim­ing this is the first ever pub­li­ca­tion of clin­i­cal study da­ta on mi­cro-dosed LSD.

PK da­ta showed that the half-life of the LSD dos­es was short. “So at 12 hours post-dose, there was no drug in the blood at any of the dos­es,” Neilo­u­far Fam­i­ly, the tri­al’s lead in­ves­ti­ga­tor, told End­points News. “And there al­so wasn’t any drug in the blood at base­line on the sixth dose.”

The da­ta sup­port fur­ther clin­i­cal de­vel­op­ment of LSD, whose psy­choac­tiv­i­ty is un­der­stood to be me­di­at­ed pri­mar­i­ly through the 5-HT2A re­cep­tor, Eleu­sis said. The com­pa­ny even plans to de­vel­op the drug to treat and pre­vent Alzheimer’s dis­ease, a field lit­tered with fail­ure and a pauci­ty of promis­ing ther­a­peu­tics in the late-stage pipeline.

But the brim­ming en­thu­si­asm comes with a healthy dose of skep­ti­cism. Crit­ics wor­ry that the bur­geon­ing psy­che­del­ic re­search could in­cen­tivize un­bri­dled use of non-phar­ma­ceu­ti­cal ver­sions of these drugs and that clin­i­cal tri­al da­ta could be cloud­ed by the fact that place­bo-con­trolled stud­ies are not nec­es­sar­i­ly dou­ble-blind­ed, be­cause it is far too easy to de­ter­mine which group of pa­tients have been giv­en a place­bo.

“The one thing that we did ex­pect — but is still re­mark­able — is the high place­bo re­sponse,” Fam­i­ly said. “Peo­ple were re­port­ing per­cep­tions of psy­choac­tive ef­fects, when lat­er on we found out they were on place­bo…but in any case, any per­cep­tions of psy­choac­tive ef­fects were very mild and they sub­sided by the end of the day, both in the ac­tive dose groups and the place­bo groups.”

Eleu­sis has a plan to hedge its Alzheimer’s bet, and to deal with the pesky prob­lem of di­ver­sion.

Be­fore div­ing in­to a Phase II ef­fi­ca­cy study in Alzheimer’s, the com­pa­ny is plan­ning an ear­ly-stage study with a com­pound — a “not-so-psy­che­del­ic” psy­che­del­ic sero­tonin 5-HT2A ag­o­nist — in oph­thal­mol­o­gy. At the mo­ment, the eye drug is at the pre­clin­i­cal stage of de­vel­op­ment.

Shlo­mi Raz

The Phase I tri­al, which is ex­pect­ed to kick off in ear­ly 2021, will pro­vide a key mech­a­nis­tic in­sight in­to how psy­che­delics could pre­vent neu­rode­gen­er­a­tion as­so­ci­at­ed with in­flam­ma­tion, Eleu­sis chief Shlo­mi Raz told End­points.

“The eye is a win­dow to the soul but al­so to the brain,” he said.”The reti­na, in par­tic­u­lar, gives us a very neat way of as­sess­ing how psy­che­delics could po­ten­tial­ly man­age neu­ro­pro­tec­tion, neu­roin­flam­ma­tion and pro­vides us a cost-ef­fec­tive proof-of-con­cept be­fore go­ing in­to — by all mea­sures —what seems to be the most ex­pen­sive type of clin­i­cal tri­al around, which is in Alzheimer’s dis­ease.”

The hope is to de­vel­op an LSD com­pound for ther­a­peu­tic use that can be used in the out­pa­tient set­ting, but psy­choac­tiv­i­ty is a risk that must be mon­i­tored, he said. The com­pa­ny says it is de­vel­op­ing a non­in­va­sive safe­ty mon­i­tor­ing tech­nol­o­gy that will be used in its clin­i­cal tri­als, and if the com­pound is ap­proved, for pa­tient use.

“In all cas­es, there’s a cal­cu­lus of safe­ty, ver­sus un­met need, and clin­i­cal util­i­ty,” he said.  “I think in the case of Alzheimer’s dis­ease, should we demon­strate that LSD in fact, is ef­fec­tive in slow­ing or halt­ing the pro­gres­sion of the dis­ease, then I think that there’s a clear jus­ti­fi­ca­tion for tak­ing that risk.”

Biotech in­vestors and CEOs see two paths to growth, but are they equal­ly vi­able?

The dynamic in the biotech market has been highly volatile in the last few years, from the high peaks immediately after the COVID vaccine in 2021, to the lowest downturns of the last 20 years in 2022. This uncertainty makes calling the exact timing of the market’s turn something of a fool’s errand, according to Dr. Chen Yu, Founder and Managing Partner of TCG Crossover (TCG X). He speaks with RBC’s Noël Brown, Head of US Biotechnology Investment Banking, about the market’s road ahead and two possible paths for growth.

Fireside chat between Hal Barron and John Carroll, UKBIO19

It’s time we talked about bio­phar­ma — live in Lon­don next week

Zoom can only go so far. And I think at this stage, we’ve all tested the limits of staying in touch — virtually. So I’m particularly happy now that we’ve revved up the travel machine to point myself to London for the first time in several years.

Whatever events we have lined up, we’ve always built in plenty of opportunities for all of us to get together and talk. For London, live, I plan to be right out front, meeting with and chatting with the small crowd of biopharma people we are hosting on October 12 at Silicon Valley Bank’s London headquarters. And there’s a lengthy mixer at the end I’m most looking forward to, with several networking openings between sessions.

Take­da to pull key hy­poparathy­roidism drug from the mar­ket af­ter years of man­u­fac­tur­ing woes

Takeda on Tuesday morning made an announcement that almost 3,000 people with the rare disease known as hypoparathyroidism were fearing.

Due to unresolved supply issues and manufacturing woes, Takeda said it will cut its losses and discontinue its hypoparathyroidism drug, known as Natpara (parathyroid hormone), halting all manufacturing of the drug by the end of 2024, but the entire inventory will be available until depleted or expired, a company spokesperson said via email.

Kaile Zagger, Infinant Health CEO

UC Davis mi­cro­bio­me spin­out re­brands in­fant sup­ple­ment busi­ness with na­ture fo­cus

When Kaile Zagger took the helm of UC Davis spinout Evolve Biosystems several months ago, the company billed itself as a probiotic maker.

However, she believes the company’s Evivo supplement designed to help infants develop a healthy gut microbiome is “so much more” — and that, she said, calls for a rebrand.

Evolve has, well, evolved into Infinant Health, the company announced on Monday. The new name is a mash-up of the words “infant” and “infinite,” representing the company’s goal of expanding beyond infant care. While its sole product, Evivo, is intended for newborns, Infinant is “quickly developing” an option for kids through the age of two.

FDA+ roundup: Ad­comm date set for Cy­to­ki­net­ics heart drug; New gener­ic drug guid­ance to re­duce fa­cil­i­ty de­lays

The FDA on Wednesday set Dec. 13 as the day that its Cardiovascular and Renal Drugs Advisory Committee will review Cytokinetics’ potential heart drug, meaning regulators aren’t likely to meet the Nov. 30 PDUFA date that was previously set.

The drug, known as omecamtiv mecarbil, read out its first Phase III in November 2020, hitting the primary endpoint of reducing the odds of hospitalization or other urgent care for heart failure by 8%. But it also missed a key secondary endpoint analysts had pegged as the key to breaking into the market, failing to significantly differ in reducing cardiovascular death from placebo.

Bob Azelby, Eliem Therapeutics CEO

Eliem says ear­li­er drug ex­po­sure is­sues have been re­solved, drops one epilep­sy in­di­ca­tion

After being forced to delay two Phase IIa trials and blaming CMC issues on a Phase Ib miss, Eliem Therapeutics believes it’s now in the clear.

The Seattle and UK-based biotech put out word Wednesday morning about how it conducted new early-stage studies to confirm why low exposure issues arose during the Phase Ib. After researchers compared the results of the studies, Eliem found “no meaningful difference” between them and ruled out CMC as the reason for the foiled Phase Ib study, the company said in a press release.

GSK touts topline win for PD-1 in head-to-head with Keytru­da — while steer­ing next big check­point drug in­to PhI­II

GSK is claiming a win for what it calls the largest head-to-head trial pitting a PD-1 against Merck’s best-selling Keytruda in a type of lung cancer, as its Jemperli met the primary endpoint of objective response rate.

In a separate positive move, GSK says it’s moving both arms of the COSTAR Lung trial into Phase III to test Jemperli as well as the TIM-3 inhibitor cobolimab.

Hesham Abdullah, GSK’s global head of oncology development, said in a statement that the two trials “support the ambition for dostarlimab to become the backbone of our ongoing immuno-oncology-based research and development programme when used alone and in combination with standard of care and future novel cancer therapies, particularly in patients with currently limited treatment options.”
