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: Roche bags 'break­through' an­ti-fi­bro­sis drug in $1.4B biotech buy­out deal

Roche is snapping up a “breakthrough” anti-fibrotic drug in a $1.4 billion buyout.

The pharma giant announced Friday that it is acquiring Promedior, primarily to get its hands on PRM-151, a recombinant form of human pentraxin-2 (PTX-2) protein that has nailed down mid-stage clinical data on idiopathic pulmonary fibrosis and demonstrating its potential for a range of fibrotic conditions.

Amarin emerges from an ex­pert pan­el re­view with a clear en­dorse­ment for Vas­cepa and high odds of suc­cess when the FDA weighs in for­mal­ly

Several FDA experts who gathered Thursday to consider the landmark approval of Vascepa to reduce cardio events in an at-risk population voiced their unease about various aspects of the efficacy and safety data, or ultimately the population it should be used to treat. But the overwhelming belief that the data pointed to the drug’s benefit and clearly outweighed risks carried the day for Amarin.

The panel voted unanimously (16 to 0) to support the company’s positive data presentation — backing an OK for expanding the label to include reducing cardio risk. The vote points Amarin $AMRN down a short path to a formal decision by the FDA, with the odds heavily in its favor. Chances are the rest of the questions about the future of this drug will be hashed out in the label’s small print.

FTC clears Bris­tol-My­ers’ $74B deal to buy Cel­gene — but Dems sig­nal a po­ten­tial hard shift against Big Phar­ma M&A

Bristol-Myers Squibb’s record $74 billion takeover of Celgene is a done deal. And it will all be over — except for the lingering complaints from die-hard Celgene investors — on Wednesday.

Like much else that’s going on in Washington these days, the vote among the 5 FTC commissioners split along party lines, with the 3 Republicans voting to clear the way and the 2 Democrats steamed over what they see as a major M&A move that will lessen competition and innovation. And that split has big implications for the M&A side of the business if the Dems take the White House in 2020.

UP­DAT­ED: In a first, FDA green-lights use of a Chi­nese built can­cer ther­a­py — and more are com­ing

Weeks after Amgen took a $2.7 billion stake in BeiGene, the Beijing-based biotech has secured its first-ever FDA approval for zanubrutinib, a BTK inhibitor, months ahead of schedule.

BeiGene’s drug, branded as Brukinsa, has secured accelerated approval for adult patients with mantle cell lymphoma (MCL) — a typically aggressive, rare, form of blood cancer — who have received at least one prior therapy.

Mer­ck buys a fledg­ling neu­rode­gen­er­a­tive biotech spawned by an old GSK dis­cov­ery al­liance. What’s up with that?

Avalon Ventures chief Jay Lichter has a well-known yen for drug development programs picked up in academia. And what he found in Haoxing Xu’s lab at the University of Michigan pricked his interest enough to launch one of his umbrella biotechs in San Diego.

Xu’s work laid the foundation for Avalon to launch Calporta, which has been working on finding small molecule agonists of TRPML1 (transient receptor potential cation channel, mucolipin subfamily, member 1) for lysosomal storage disorders. And that pathway, they believe, points to new approaches on major market neurodegenerative diseases like Parkinson’s, ALS and Alzheimer’s.

No­var­tis scores its lat­est FDA OK — this time for a new sick­le cell dis­ease drug picked up in a $665M deal

Novartis’ decision to buy Oklahoma-based biotech Selexys 3 years ago for up to $665 million has paid off with an FDA approval today.

Blessed with the FDA’s breakthrough drug designation for a speedy review, the pharma giant has pinned down an approval for crizanlizumab, a new therapy designed to reduce the frequency of painful incidents of vaso-occlusive crises among sickle cell disease patients 16 or older.
