Small AI biotech BioX­cel surges on pos­i­tive PhI­II re­sults, set­ting up de­men­tia and Alzheimer’s test

A small biotech added a few hun­dred mil­lion dol­lars in mar­ket val­ue Mon­day morn­ing af­ter an­nounc­ing pos­i­tive Phase III re­sults from their lead neu­rol­o­gy drug.

The drug, known as BX­CL501, comes from BioX­cel, one of a slate of biotechs that has raised mil­lions in re­cent years on the promise of us­ing ar­ti­fi­cial in­tel­li­gence and oth­er ad­vanced com­pu­ta­tion­al tech­niques to speed up the slug­gish pace of drug de­vel­op­ment. Sim­i­lar to the more promi­nent Re­cur­sion, the com­pa­ny aimed to use its tech to find com­pounds that oth­er com­pa­nies or re­searchers had val­i­dat­ed to some de­gree and re­pur­pose them, par­tic­u­lar­ly in the ar­eas of neu­rode­gen­er­a­tion, men­tal health and im­muno-on­col­o­gy.

Now, in a pair of near­ly 400-per­son Phase III tri­als for bipo­lar dis­or­der and schiz­o­phre­nia, the lead drug ef­fec­tive­ly calmed pa­tients’ ag­i­ta­tion, as mea­sured by a stan­dard scor­ing sys­tem. It al­so hit sec­ondary end­points, show­ing the ef­fect be­gan as ear­ly as 20 min­utes af­ter dos­ing.

The com­pa­ny said it plans to sub­mit for ap­proval in the first quar­ter of 2021. Their stock soared 31%, from $52.99 to $69.40 pre-mar­ket on the news.

“In our view, these da­ta are very com­pelling,” Guggen­heim Part­ners’ Yatin Sune­ja wrote in a note to in­vestors, “and we ex­pect ap­proval in both in­di­ca­tions.”

Sune­ja said the re­sults looked “in-line or bet­ter” than Ada­suve, the Alexza drug used as the stan­dard of care for ag­i­ta­tion. She pre­dict­ed $500 mil­lion in peak sales.

When BioX­cel filed for its IPO in 2017, though, the com­pa­ny spent as much time talk­ing about its lead drug’s po­ten­tial in Alzheimer’s and de­men­tia as it did about schiz­o­phre­nia. Al­though fur­ther be­hind, that in­di­ca­tion — so sought out by biotech in re­cent years — re­mains the com­pa­ny’s largest mar­ket po­ten­tial. A Phase I/II tri­al is now un­der­way.

“The larg­er fo­cus for in­vestors is de­men­tia, larg­er mar­ket than schiz­o­phre­nia/bipo­lar,” Sun­Trust’s Robyn Kar­nauskas wrote in a note to in­vestors.

She said the Phase III num­bers sup­port­ed $800 mil­lion in peak sales, while point­ing to even greater po­ten­tial in neu­rode­gen­er­a­tion. “We be­lieve da­ta helps val­i­date tar­get­ing a cen­tral mech­a­nism re­lat­ed to acute ag­i­ta­tion and as such, should help ex­pand BX­CL501 in­to ad­di­tion­al in­di­ca­tions,” she said.

That mech­a­nism in­volves a re­for­mu­la­tion of Pifz­er’s 21-year-old se­da­tion drug Pre­cedex. BioX­cel cre­at­ed a sub­lin­gual ver­sion of the drug that can be giv­en eas­i­ly and pro­duce a calm­ing ef­fect with­out knock­ing a pa­tient out. Specif­i­cal­ly, it ac­ti­vat­ed the al­pha-2 re­cep­tor, the path­way through which nor­ep­i­neph­rine, among oth­er neu­ro-chem­i­cals, trav­els.

In the Phase III stud­ies, the drug re­duced pa­tients’ “ex­cite­ment” score on the Pos­i­tive and Neg­a­tive Syn­drome Scale for schiz­o­phre­nia and bipo­lar dis­or­der. Across 381 schiz­o­phre­nia pa­tients, those on the high dose had 10.3 point re­duc­tion af­ter 2 hours, com­pared with 8.5 on the low dose and 4.8 on place­bo. Across 378 bipo­lar pa­tients, the high dose arm and 10.4 point re­duc­tion, com­pared with 9.1 on the low dose and 5 on place­bo.

Pa­tients al­so showed sta­tis­ti­cal­ly sig­nif­i­cant im­prove­ments on the Ag­i­ta­tion and Calm­ness Eval­u­a­tion Scale (ACES), and clin­i­cal glob­al im­pres­sion.

Biotech Half­time Re­port: Af­ter a bumpy year, is biotech ready to re­bound?

The biotech sector has come down firmly from the highs of February as negative sentiment takes hold. The sector had a major boost of optimism from the success of the COVID-19 vaccines, making investors keenly aware of the potential of biopharma R&D engines. But from early this year, clinical trial, regulatory and access setbacks have reminded investors of the sector’s inherent risks.

RBC Capital Markets recently surveyed investors to take the temperature of the market, a mix of specialists/generalists and long-only/ long-short investment strategies. Heading into the second half of the year, investors mostly see the sector as undervalued (49%), a large change from the first half of the year when only 20% rated it as undervalued. Around 41% of investors now believe that biotech will underperform the S&P500 in the second half of 2021. Despite that view, 54% plan to maintain their position in the market and 41% still plan to increase their holdings.

Bio­gen hit by ALS set­back with PhI­II fail­ure for tofersen — but fol­lows a fa­mil­iar strat­e­gy high­light­ing the pos­i­tive

Patients and analysts waiting to hear Sunday how Biogen’s SOD1-ALS drug tofersen fared in Phase III didn’t have to wait long for the top-line result they were all waiting for. The drug failed the primary endpoint on significantly improving the functional and neurologic decline of patients over 28 weeks as well as the extension period for continued observation.

In fact, there was very little difference in response.

UP­DAT­ED: Boehringer nabs FDA's first in­ter­change­abil­i­ty des­ig­na­tion for its Hu­mi­ra com­peti­tor — but will it mat­ter?

The FDA late Friday awarded Boehringer Ingelheim the first interchangeability designation for its Humira biosimilar Cyltezo, meaning that when it launches in July 2023, pharmacists will be able to automatically substitute the Boehringer’s version for AbbVie’s mega-blockbuster without a doctor’s input.

The designation will likely give Boehringer, which first won approval for Cyltezo in 2017, the leg up on a crowded field of Humira competitors.

Ver­tex gets much-need­ed win with ‘ex­tra­or­di­nary’ first pa­tient re­sults on po­ten­tial di­a­betes cure

Vertex said Monday that the first patient dosed with its cell therapy for type 1 diabetes saw their need for insulin injections vanish almost entirely, a key early step in the decades-long effort to develop a curative treatment for the chronic disease.

The patient, who had suffered five potentially life-threatening hypoglycemic — or low blood sugar — episodes in the year before the therapy, was injected with synthetic insulin-producing cells. After 90 days, the patient’s new cells produced insulin steadily and ramped up their insulin production after a meal like normal cells do, as measured by a standard biomarker for insulin production.

No­var­tis de­vel­op­ment chief John Tsai: 'We go deep in the new plat­form­s'

During our recent European Biopharma Summit, I talked with Novartis development chief John Tsai about his experiences over the 3-plus years he’s been at the pharma giant. You can read the transcript below or listen to the exchange in the link above.

John Carroll: I followed your career for quite some time. You’ve had more than 20 years in big pharma R&D and you’ve obviously seen quite a lot. I really was curious about what it was like for you three and a half years ago when you took over as R&D chief at Novartis. Obviously a big move, a lot of changes. You went to work for the former R&D chief of Novartis, Vas Narasimhan, who had his own track record there. So what was the biggest adjustment when you went into this position?

Two drug­mak­ers hit with PDU­FA date de­lays from FDA amid back­log of in­spec­tions

As the FDA is weighed down with more and more pandemic responsibilities, the agency is beginning to miss PDUFA dates with more frequency too. Two different companies on Monday said they received notices that the FDA has not completed their drug reviews on time.

The review of an NDA for Avadel Pharmaceuticals’ candidate treatment for narcolepsy is not coming this month, the company said, and the review of UCB’s BLA for bimekizumab, used to treat moderate to severe plaque psoriasis, will miss its target date as well.

Phath­om's old Take­da drug bests Pre­vacid in a PhI­II GI tri­al. Next stop? The FDA

There’s no time for rest in biopharma — at least not at Phathom Pharmaceuticals. Just over a month after submitting two NDAs for its lead acid-fighter vonoprazan, the biotech is already lining up a third, and collecting an extra $50 million to push things along.

Vonoprazan met its primary non-inferiority endpoints in a Phase III study comparing it to standard-of-care Prevacid in a type of gastroesophageal reflux disease (GERD) called erosive esophagitis (EE). It also proved superior to the popular heartburn drug by multiple measures, including healing rate and maintenance of healing.

Thomas Lingelbach, Valneva CEO

Small biotech says its Covid-19 vac­cine spurs more an­ti­bod­ies than As­traZeneca’s. Will sup­ply deals come now?

In a first, a small runner-up vaccine developer says its own Covid-19 jab has induced “superior neutralizing antibody titer levels” over AstraZeneca’s AZD1222 when pitted head-to-head in a Phase III trial.

That and non-inferiority in seroconversion rate were the co-primary endpoints of the trial, which recruited 4,012 adult volunteers across the UK.

But on the exploratory endpoint of Covid-19 case counts, Valneva notes that both treatment groups saw a similar number of infections.
