PhI­II Alzheimer’s drug goes bust — and a ma­jor set­back at Eli Lil­ly and As­traZeneca may doom the class

An­oth­er big Phase III Alzheimer’s pro­gram is be­ing scrapped at Eli Lil­ly $LLY and As­traZeneca $AZN, of­fer­ing fresh ev­i­dence that the en­tire BACE class may be com­plete­ly use­less in slow­ing or pre­vent­ing the dis­ease in symp­to­matic pa­tients.

The drug this time is lan­abece­s­tat, which Lil­ly grabbed close to 4 years ago in a $500 mil­lion pact with As­traZeneca — a mod­est $50 mil­lion in cash. At the time, Lil­ly was plug­ging a gap in its Alzheimer’s pipeline af­ter the fail­ure of its own BACE ef­fort due to tox­i­c­i­ty is­sues with that par­tic­u­lar med­ica­tion.

This time, fin­gers are point­ing to the en­tire class in a flop that will like­ly cause fresh angst over a huge ques­tion: Is amy­loid be­ta re­al­ly the cul­prit here?

The BACE the­o­ry is easy enough to un­der­stand. Mov­ing up­stream in the bi­o­log­i­cal process for the pro­duc­tion of amy­loid be­ta, re­searchers hoped to bend the course of the dis­ease by clos­ing the tap on tox­ic pro­teins. Mer­ck was the first to try it in a pair of Phase III stud­ies and sim­ply con­clud­ed it was a bust, prob­a­bly on­ly the­o­ret­i­cal­ly use­ful now in pre-symp­to­matic pa­tients or as a com­bo.

Eli Lil­ly will now move to shut­ter two big tri­als — the AMA­RANTH tri­al, in ear­ly Alzheimer’s dis­ease, and the DAY­BREAK-ALZ tri­al, in mild Alzheimer’s dis­ease de­men­tia — af­ter the mon­i­tor­ing com­mit­tee called it on fu­til­i­ty.

The fail­ure of Lil­ly and As­traZeneca’s drug may sound the death knell on a so­lo BACE strat­e­gy in ear­ly and mild pa­tients, even though Bio­gen just tout­ed its Phase II BACE study herald­ing the bio­mark­er suc­cess on amy­loid be­ta along­side an ab­sence of a sta­tis­ti­cal­ly sig­nif­i­cant im­pact on cog­ni­tion — much the same as what Mer­ck was track­ing.

In lan­abece­s­tat’s case, we on­ly know that the drug ap­peared safe and in­ef­fec­tive, no hard da­ta are avail­able yet.

Why keep try­ing af­ter more than a decade of fail­ures? As­traZeneca an­swered that ques­tion when Pas­cal So­ri­ot once es­ti­mat­ed that this drug could earn $5 bil­lion a year. 

That’s not go­ing to hap­pen, of course. But de­vel­op­ers keep ham­mer­ing away at it — even as big play­ers re­main puz­zled about what caus­es the dis­ease. 

Fol­low­ing the fail­ure of solanezum­ab in three straight piv­otal stud­ies, Eli Lil­ly doesn’t have much of a cred­i­ble pipeline left in the field. And af­ter Pfiz­er bowed out fol­low­ing big re­treats at GSK and As­traZeneca, Big Phar­ma may be do­ing some ad­di­tion­al soul search­ing about its role in R&D. Lil­ly, though, vows to sol­dier on af­ter spend­ing bil­lions on fail­ure.

“Lil­ly re­mains ded­i­cat­ed to Alzheimer’s dis­ease re­search as we have been for the last three decades,” says R&D chief Daniel Skovron­sky. “We won’t give up on find­ing a so­lu­tion for Alzheimer’s pa­tients.”

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.
