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.”

Pfiz­er lays off em­ploy­ees at Cal­i­for­nia and Con­necti­cut sites

Pfizer has laid off employees at its La Jolla, CA, and Groton, CT sites, according to multiple LinkedIn posts from former employees.

The Big Pharma confirmed to Endpoints News it has let go of some employees, but a spokesperson declined to specify how many workers were impacted and the exact locations affected. Earlier this month, the drug developer had confirmed to Endpoints it was sharpening its focus and doing away with some early research on areas such as rare disease, oncology and gene therapies.

Lil­ly en­ters ripe BTK field with quick FDA nod in man­tle cell lym­phoma

Eli Lilly has succeeded in its attempt to get the first non-covalent version of Bruton’s tyrosine kinase, or BTK, inhibitors to market, pushing it past rival Merck.

The FDA gave an accelerated nod to Lilly’s daily oral med, to be sold as Jaypirca, for patients with relapsed or refractory mantle cell lymphoma.

The agency’s green light, disclosed by the Indianapolis Big Pharma on Friday afternoon, catapults Lilly into a field dominated by covalent BTK inhibitors, which includes AbbVie and Johnson & Johnson’s Imbruvica, AstraZeneca’s Calquence and BeiGene’s Brukinsa.

No­var­tis' ap­proved sick­le cell dis­ease drug fails to beat place­bo in PhI­II

Novartis’ sickle cell drug, approved in 2019 and branded as Adakveo, has failed an ongoing Phase III, according to preliminary results.

The Swiss pharma giant unveiled early data from the ongoing STAND Phase III study on Friday, saying that crizanlizumab showed no statistically significant difference between the drug at two different dose levels compared to placebo in annualized rates of vaso-occlusive crises that lead to a healthcare visit over the first year since being randomized into the trial.

No­vavax gets ready to take an­oth­er shot at Covid vac­cine mar­ket with next sea­son plans

While mRNA took center stage at yesterday’s FDA vaccine advisory committee meeting, Novavax announced its plans to deliver an updated protein-based vaccine based on new guidance.

Vaccines and Related Biological Products Advisory Committee (VRBPAC) members voted unanimously in favor of “harmonizing” Covid vaccine compositions, meaning all future vaccine recipients would receive a bivalent vaccine, regardless of whether they’ve gotten their primary series.

FDA ap­proves an­oth­er in­di­ca­tion for Keytru­da, this time in the ad­ju­vant NSCLC set­ting

Merck’s blockbuster cancer treatment Keytruda has been handed another indication by the FDA.

The US regulator announced on Thursday that it has approved Keytruda to serve as an adjuvant treatment for non-small cell lung cancer (NSCLC), which is its fifth indication in NSCLC and 34th indication overall.

According to a Merck release, the approval is based on data from a Phase III trial, dubbed Keynote-091, which measured disease-free survival in patients who received chemotherapy following surgery. The data from Merck displayed that Keytruda cut down on the risk of disease recurrence or death by 27% versus placebo.

J&J, Leg­end say Carvyk­ti beat stan­dard ther­a­py in ear­li­er-line blood can­cer

J&J and Legend Biotech’s next step in turning their CAR-T therapy Carvykti into a potential megablockbuster has succeeded, the companies said Friday.

Carvykti achieved the primary endpoint — progression-free survival — in an open-label Phase III study testing the treatment in second- to fourth-line multiple myeloma patients. The CARTITUDE-4 trial, for which there aren’t any hard data yet, represents the biggest development for Carvykti’s ability to compete with Bristol Myers Squibb’s Abecma since its approval last February.

Dutch biotech starts liq­ui­da­tion af­ter end­ing PhI­II in GVHD

A 13-year-old Dutch biotech is going through a liquidation process after an unexpected end to its Phase III trial testing whether its combination of two monoclonal antibodies was superior to Incyte’s Jakafi.

Xenikos had hoped to prove its investigational therapy, named T-Guard, was better than Jakafi at garnering a complete response in patients experiencing life-threatening complications in which new cells from a hematopoietic stem cell transplant begin to fight the body. Jakafi was approved for the indication, steroid-refractory acute graft-versus-host disease, in May 2019.
