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.

Nick Galakatos, Blackstone global head of life sciences

Nick Galakatos and the Black­stone team now have a record $4.6B to in­vest in bio­phar­ma, with a big fo­cus on push­ing com­pa­nies over the top

Nick Galakatos and his team at Blackstone Life Sciences have seen their biggest opportunities swell up in mostly established players who don’t have all the money they need to accomplish everything on the to-do list. And right now, with the industry booming, that’s a long list with some hefty needs.

The Blackstone team has neatly tied up the largest private fund ever raised in life sciences for making big dreams come true in biopharma. Late Thursday, Blackstone put out word that they had closed their highly anticipated fund with the projected $4.6 billion all in.

UP­DAT­ED: Bio­gen shares spike as ex­ecs com­plete a de­layed pitch for their con­tro­ver­sial Alzheimer's drug — the next move be­longs to the FDA

Biogen is stepping out onto the high wire today, reporting that the team working on the controversial Alzheimer’s drug aducanumab has now completed their submission to the FDA. And they want the agency to bless it with a priority review that would cut the agency’s decision-making time to a mere 6 months.

The news drove a 10% spike in Biogen’s stock $BIIB ahead of the bell.

Part of that spike can be attributed to a relief rally. Biogen execs rattled backers and a host of analysts earlier in the year when they unexpectedly delayed their filing to the third quarter. That delay provoked all manner of speculation after CEO Michel Vounatsos and R&D chief Al Sandrock failed to persuade influential observers that the pandemic and other factors had slowed the timeline for filing. Actually making the pitch at least satisfies skeptics that the FDA was not likely pushing back as Biogen was pushing in. From the start, Biogen execs claimed that they were doing everything in cooperation with the FDA, saying that regulators had signaled their interest in reviewing the submission.

Gilead boasts of pos­i­tive remde­sivir da­ta on mor­tal­i­ty — but their analy­sis pro­vokes the skep­tics

Gilead is surging again off data that suggest its antiviral remdesivir might improve survival.

The new data come from an analysis Gilead conducted comparing the death rate and recovery time of patients in one of its remdesivir trials to a group of 800 patients “with similar baseline characteristics and disease severity” who received only standard-of-care around the same time. The result, they said, suggested that patients who received remdesivir had a 62% better chance at surviving than those who did not.

OWS shifts spot­light to drugs to fight Covid-19, hand­ing Re­gen­eron $450M to be­gin large scale man­u­fac­tur­ing in the US

The US government is on a spending spree. And after committing billions to vaccines defense operations are now doling out more of the big bucks through Operation Warp Speed to back a rapid flip of a drug into the market to stop Covid-19 from ravaging patients — possibly inside of 2 months.

The beneficiary this morning is Regeneron, the big biotech engaged in a frenzied race to develop an antibody cocktail called REGN-COV2 that just started a late-stage program to prove its worth in fighting the virus. BARDA and the Department of Defense are awarding Regeneron a $450 million contract to cover bulk delivery of the cocktail starting as early as late summer, with money added for fill/finish and storage activities.

Hal Barron, GSK

Win or lose on the mar­ket­ing OK, the FDA just gunned down GSK’s bright hopes for their BC­MA ther­a­py

The FDA’s ODAC — the Oncologic Drugs Advisory Committee — has a well-known bias in favor of adding new cancer drugs to the market, even if efficacy is at best marginal and serious safety issues demand careful management.

Doctors want as many arrows in their quiver as they can get. And when patients are dying after failing multiple drugs, why not give it a go one more time?

GlaxoSmithKline, though, is about to test out how their new BCMA antibody drug conjugate belantamab mafodotin can do after being mauled in an in-house FDA review, ahead of the Tuesday expert panel discussion. Even if the agency goes ahead with an expected green light, this drug will likely be constrained to a small niche — icing any plans they may have for making waves in oncology anytime soon.

Covid-19 roundup: BioN­Tech go­ing head-to-head with Mod­er­na as PhI­II mR­NA launch looms; Tri­al on Shin­zo Abe’s once-fa­vorite an­tivi­ral is in­con­clu­sive

It’s a race to the Phase III finish line now for the 2 leading mRNA vaccines in the pipeline for Covid-19.

BioNTech chief Ugur Sahin told the Wall Street Journal that his company will start Phase III testing of their vaccine later this month, setting them up to lateral the data to regulators before the end of this year.

That puts them essentially on the exact same schedule as Moderna is dedicated to. The Massachusetts rival to BioNTech also expects to launch Phase III this month. Lots of rumors have circulated about delays and conflict among the scientists advancing the Moderna jab, but the biotech has consistently stuck to its plan to start a late-stage pivotal this month.

Af­ter psilo­cy­bin and ke­t­a­mine, a new biotech comes along de­vel­op­ing a drug Scott Got­tlieb fought

Andrew Kruegel was six years into his chemistry work at Columbia University, when, one day in August 2016, he learned he might have only 30 days before the government made him destroy his research.

Kruegel had been studying kratom, a leaf long used in Southeast Asia as a stimulant or for pain. It had opioid-like properties, he found, but seemed to offer pain relief without the addictive potential or respiratory side effects of traditional opioids — a riddle that might help illuminate how human opioid receptors work.

The home run count: The $100M+ mega-round boom in biotech in­spired a $7.3B feed­ing fren­zy — so far this year

Over the last 6 months there’s been a blizzard of money piling up drifts of the green stuff through the biotech landscape. And the forecast calls for more cash windfalls ahead.

Even as a global pandemic has killed more than half a million people, blighted economies and divided nations over the proper response, it’s also helped ignite an unprecedented burst of big-time investing. And not just in Covid-19 deals, as we’ve looked at before.

An­oth­er biotech IPO set-up? Multi­na­tion­al biotech leaps from round to round, scoop­ing up cash at a blis­ter­ing pace

A short four months after announcing a $75 million haul in Series B+ fundraising, the multinational biotech Harbour BioMed pulled in another round of investments and eclipsed the nine-digit mark in the process.

Harbour completed its Series C financing, the company announced Thursday morning, raising $102.8 million and bringing its total investment sum to over $300 million since its founding in late 2016. The biotech plans to use the money to transition early-stage candidates from the discovery phase, fund candidates already in the clinic, and prep late-stage candidates for commercialization.
