Sem­ma steps to­ward the clin­ic af­ter demon­strat­ing ef­fect of po­ten­tial di­a­betes cure in land­mark an­i­mal stud­ies

The re­search team at the well-fund­ed Sem­ma Ther­a­peu­tics has cleared one of the last re­main­ing hur­dles to get­ting a po­ten­tial cure for di­a­betes in­to hu­man stud­ies. And if they’re right, it marks a ma­jor pre­clin­i­cal mile­stone for a resur­gent re­gen­er­a­tive med­i­cine field fo­cused on a new gen­er­a­tion of stem cell ther­a­pies.

Fe­li­cia Pagli­u­ca

Fe­li­cia Pagli­u­ca, VP of cell bi­ol­o­gy re­search and de­vel­op­ment at the Cam­bridge, MA-based biotech, told the 2019 In­ter­na­tion­al So­ci­ety for Stem Cell Re­search meet­ing in LA Sat­ur­day that their stem cell-de­rived islets per­formed as hoped for — pro­duc­ing in­sulin — in a study in­volv­ing non-hu­man pri­mates whose im­mune sys­tems had been flat­tened to pre­vent a re­jec­tion. In a sep­a­rate study in­volv­ing two pigs, a pack­age of these en­gi­neered islets con­tained in a spe­cial­ly de­signed pack­age were used suc­cess­ful­ly to gen­er­ate in­sulin with­out need­ing an im­muno­sup­pres­sant to pro­tect against a re­ac­tion.

“For the first time ever the de­vice pro­tects the cell,” Pagli­u­ca told me in a pre­view of to­day’s ses­sion, of­fer­ing ev­i­dence from a large an­i­mal mod­el that the tech­nol­o­gy func­tions with blood glu­cose lev­els, spurring in­sulin se­cre­tion as need­ed. “They re­al­ly show quite con­sis­tent re­spon­sive­ness.”

And that’s with­out fi­bro­sis, with­out cell suf­fo­ca­tion, while watch­ing the in­te­gra­tion of cell ther­a­py in­to host tis­sue.

Bas­tiano San­na

It’s ex­cit­ing, says Sem­ma CEO Bas­tiano San­na, to see the “cu­ra­tive po­ten­tial” of this cell ther­a­py.

Re­al­ly? A cure? For a mass mar­ket dis­ease like di­a­betes?

If that all seems a bit too won­der­ful to be be­lieved, think about where Pagli­u­ca is com­ing from. Stem cell ther­a­pies had their hey­day well over a decade ago as the next big thing in med­i­cine — an overnight sen­sa­tion which sput­tered out in fail­ure as the sur­vivors went back in­to the lab to do the hard work nec­es­sary to make it a re­al­i­ty. That long pe­ri­od of qui­et bred con­sid­er­able skep­ti­cism, es­pe­cial­ly af­ter the first wave of promised cures failed to ma­te­ri­al­ize. And she’s watched it play out as re­gen­er­a­tive med­i­cine made its come­back.

One of those pi­o­neer­ing sci­en­tists who stayed in the lab was Sem­ma sci­en­tif­ic founder and Har­vard pro­fes­sor Doug Melton, who pub­lished a land­mark study 5 years ago out­lin­ing how he had suc­cess­ful­ly used stem cells to cre­ate in­sulin-pro­duc­ing pan­cre­at­ic be­ta cells that were in­sert­ed in bulk in­to mice and suc­cess­ful­ly pro­tect­ed from an im­mune re­sponse — a break­through in re­gen­er­a­tive med­i­cine. And he’d been work­ing on the cure for more than 20 years, which he start­ed fol­low­ing his son’s di­ag­no­sis of Type 1 di­a­betes. 

They’ve raised $158 mil­lion over 4 years at Sem­ma to get to this stage, stand­ing on the thresh­old of a pair of small hu­man stud­ies set to launch next year. They’ll now see if they can re­pro­duce in hu­mans what they did in the non-hu­man pri­mates and pigs: first by run­ning a small study with an im­muno­sup­pres­sant, fol­lowed by the use of their de­vice in an­oth­er study lat­er next year that will avoid im­muno­sup­pres­sants.

CAR-T and gene ther­a­pies have come along to demon­strate cu­ra­tive po­ten­tial, but the CEO says it’s been frus­trat­ing to see the first wave of these ther­a­pies tar­get­ed at tiny pa­tient pop­u­la­tions. “We’re very ex­cit­ed about bring­ing the cu­ra­tive po­ten­tial of cell ther­a­pies in­to a large in­di­ca­tion.”

They’re tak­ing it step by step.

No­body is rolling out a mass tri­al for Type 2 di­a­betes. The first goal is to go af­ter some of the Type 1 di­a­betes pa­tients who are the hard­est to treat, with nowhere left to turn to rein in the au­toim­mune dis­ease. Af­ter that, they can turn to the broad­er Type 1 pop­u­la­tion be­fore mov­ing on, per­haps in­to par­tic­u­lar sub­groups of Type 2.

Ini­tial­ly, the goal will be to get the islets to do the work need­ed to safe­ly pro­duce in­sulin for these pa­tients at a re­li­able lev­el. These stem cell-de­rived islets will have to be able to be man­u­fac­tured at scale. And there’s work un­der­way to see if there’s a uni­ver­sal cell de­sign that can be used to avoid the need for the de­vice they use — some­thing Melton com­pares to a tea bag.

Up­dat­ed: FDA re­mains silent on or­phan drug ex­clu­siv­i­ty af­ter last year's court loss

Since losing a controversial court case over orphan drug exclusivity last year, the FDA’s Office of Orphan Products Development has remained entirely silent on orphan exclusivity for any product approved since last November, leaving many sponsors in limbo on what to expect.

That silence means that for more than 70 orphan-designated indications for more than 60 products, OOPD has issued no public determination on the seven-year orphan exclusivity in the Orange Book, and no new listings of orphan exclusivity appear in OOPD’s searchable database, as highlighted recently by George O’Brien, a partner in Mayer Brown’s Washington, DC office.

Talk therapy didn’t help Lily with attention deficit hyperactivity disorder, or ADHD. But a video game did.

As the 10-year-old zooms through icy waters and targets flying creatures on the snow-capped planet Frigidus, she builds attention skills, thanks to Akili Interactive Labs’ video game EndeavorRx. She’s now less anxious and scattered, allowing her to stay on a low dose of ADHD medication, according to her mom Violet Vu.

Eli Lil­ly’s Alzheimer’s drug clears more amy­loid ear­ly than Aduhelm in first-ever head-to-head. Will it mat­ter?

Ahead of the FDA’s decision on Eli Lilly’s Alzheimer’s drug donanemab in February, the Big Pharma is dropping a first cut of data from one of the more interesting trials — but less important in a regulatory sense — at an Alzheimer’s conference in San Francisco.

In the unblinded 148-person study, Eli Lilly pitted its drug against Aduhelm, Biogen’s drug that won FDA approval but lost Medicare coverage outside of clinical trials. Notably, the study didn’t look at clinical outcomes, but rather the clearance of amyloid, a protein whose buildup is associated with Alzheimer’s disease, in the brain.

Pfiz­er and Roivant team up again for an­oth­er 'Van­t', set­ting up an­ti-in­flam­ma­to­ry show­down with Prometheus

Pfizer and Roivant are teaming up to launch a new ‘Vant’ aimed at bringing a mid-stage anti-inflammatory drug to market, the pair announced Thursday.

There’s no name for the startup yet, nor are there any employees. Thus far, the new company and Roivant can be considered “one and the same,” Roivant CEO Matt Gline tells Endpoints News. But Pfizer is so enthusiastic about the target that it elected to keep 25% of equity in the drug rather than take upfront cash from Roivant, Gline said.

As com­peti­tors near FDA goal­post, Roche spells out its re­peat Alzheimer's set­back

Before Roche can turn all eyes on a new version of its more-than-once-failed Alzheimer’s drug gantenerumab, the Big Pharma had to flesh out data on the November topline failure at an annual conference buzzier than in years past thanks to hotly watched rivals in the field: Eisai and Biogen’s lecanemab, and Eli Lilly’s donanemab.

There was less than a 10% difference between Roche’s drug and placebo at slowing cognitive decline across two Phase III trials, which combined enrolled nearly 2,000 Alzheimer’s patients. In its presentation at the conference Wednesday, Roche said it saw less sweeping away of toxic proteins than it had anticipated. For years, researchers and investors have put their resources behind the idea that more amyloid removal would equate to reduced cognitive decline.

SQZ Biotech slash­es head­count by 60% as founder/CEO hits ex­it — while Syn­log­ic lays off 25%

It’s a tough time for early-stage companies developing highly promising, but largely unproven, new technologies.

Just ask SQZ Biotechnologies and Synlogic. The former is bidding farewell to its founder and CEO and slashing the headcount by 60% as it pivots from its original cell therapy platform to a next-gen approach; the latter — a synthetic biology play founded by MIT’s Jim Collins and Tim Lu — is similarly “optimizing” the company to focus on lead programs. The resulting realignment means 25% of the staffers will be laid off.

Ei­sai’s ex­pand­ed Alzheimer’s da­ta leave open ques­tions about safe­ty and clin­i­cal ben­e­fit

Researchers still have key questions about Eisai’s investigational Alzheimer’s drug lecanemab following the publication of more Phase III data in the New England Journal of Medicine Tuesday night.

In the paper, which was released in conjunction with presentations at an Alzheimer’s conference, trial investigators write that a definition of clinical meaningfulness “has not been established.” And the relative lack of new information, following topline data unveiled in September, left experts asking for more — setting up a potential showdown to precisely define how big a difference the drug makes in patients’ lives.

Sanofi and DN­Di aim to elim­i­nate sleep­ing sick­ness in Africa with promis­ing Ph II/III re­sults for new drug

The Drugs for Neglected Diseases initiative (DNDi) and Sanofi today said that their potential sleeping sickness treatment saw success rates of up to 95% from a Phase II/III study investigating the safety and efficacy of single-dose acoziborole.

The potentially transformative treatment for sleeping sickness would mainly be targeted at African countries, according to data published today in The Lancet Infectious Diseases medical journal. The clinical trial was led by DNDi and its partners in the Democratic Republic of the Congo (DRC) and Guinea, with the authors noting:

Vi­iV dri­ves new cor­po­rate coali­tion in­clud­ing Uber, Tin­der and Wal­mart, aimed at end­ing HIV

ViiV Healthcare is pulling together an eclectic coalition of consumer businesses in a new White House-endorsed effort to end HIV by the end of the decade.

The new US Business Action to End HIV includes pharma and health companies — Gilead Sciences, CVS Health and Walgreens — but extends to a wide range of consumer companies that includes Tinder, Uber and Walmart.

ViiV is the catalyst for the group, plunking down more than half a million dollars in seed money and taking on ringmaster duties for launch today on World AIDS Day, but co-creator Health Action Alliance will organize joint activities going forward. ViiV and the alliance want and expect more companies to not only join the effort, but also pitch in funding.
