Eli Lil­ly jumps in­to a $473M hunt with Sig­ilon for the Holy Grail in di­a­betes cell ther­a­pies

Stem cell ther­a­pies have gone through every stage of the long and painful hype cy­cle for emerg­ing drug tech­nolo­gies: Start­ing with wild­ly in­flat­ed ear­ly ex­pec­ta­tions through bit­ter dis­il­lu­sion­ment, a trough of de­spair and on to a slow and pa­tient re­cov­ery brought about by years of dili­gent re­search work in the lab.

Paul Wot­ton, who’s seen it all, be­lieves he can now see the off-the-shelf cell prod­ucts of the fu­ture — en­cap­su­lat­ed in what they’ve dubbed Afi­bromer plat­form tech — tak­ing shape at the end of the new­ly ris­ing curve.

As the found­ing CEO at Flag­ship-seed­ed Sig­ilon, a start­up launched last year in Cam­bridge, MA with a $23.5 mil­lion round, he’s now un­veil­ing one of the fi­nal re­main­ing pieces nec­es­sary for a come­back: An al­liance with a Big Phar­ma part­ner.

To­day Sig­ilon is an­nounc­ing a $473 mil­lion pact with Eli Lil­ly — which is step­ping out un­der a bold­er R&D chief in Dan Skovron­sky — to dri­ve their stem cell work on Type 1 di­a­betes in­to the clin­ic, with $63 mil­lion of that in an up­front and the rest divvied up with a goal of ful­ly fund­ing the de­vel­op­ment of a durable new ther­a­py for the dis­ease. Eli Lil­ly is al­so mak­ing an undis­closed eq­ui­ty in­vest­ment in the com­pa­ny.

“I think we’ve kind of dis­cov­ered the Holy Grail to make cell ther­a­py a re­al­i­ty,” says Wot­ton. 

While re­searchers fig­ured out a long time ago how to get stem cells to trans­form in­to in­sulin pro­duc­ing pan­cre­at­ic be­ta cells for di­a­bet­ics, get­ting them in­to the body to do their work with­out trig­ger­ing a se­vere im­mune re­ac­tion has been an in­sur­mount­able ob­sta­cle.

Bob Langer

But af­ter test­ing new tech out of the labs of MIT’s Bob Langer and Daniel An­der­son in ro­dents as well as non-hu­man pri­mates, Sig­ilon be­lieves it’s with­in a cou­ple of years of start­ing work on a hu­man clin­i­cal tri­al — a ma­jor step to­ward ob­tain­ing clear proof-of-con­cept da­ta. They be­lieve they can de­liv­er islet cells to the body, and keep it hid­den from the im­mune sys­tem, pre­vent­ing fi­bro­sis that can choke cells of nu­tri­tion and oxy­gen. And while they are now pi­o­neer­ing a ground­break­ing field, there are sol­id pre­clin­i­cal rea­sons to be­lieve that they can make the hur­dle in hu­mans.

“Bob Langer’s team screened 600 mol­e­cules that could evade the im­mune sys­tem,” says Wot­ton. And they be­lieve they are on to the kind of en­cap­su­lat­ed cell-based ther­a­pies that can be de­liv­ered in wa­ter sol­u­ble poly­mers — Langer’s sweet spot in the lab — nec­es­sary for de­vis­ing a ther­a­py that could cre­ate a re­li­able sup­ply of in­sulin for pa­tients.

They’re not alone here. Har­vard spin­out Sem­ma re­cent­ly gar­nered a $114 mil­lion megaround to see if their “tea bag” tech for pro­duc­ing in­sulin can do the same thing.

It won’t be quick. There’s no hard time­line on the di­a­betes side, but Sig­ilon is with­in a cou­ple of years of mov­ing a pro­gram in­to the clin­ic us­ing the same tech plat­form to spawn fac­tor VI­II and IX for he­mo­phil­ia pa­tients. And that could help pave the way to a clin­i­cal study in di­a­betes soon af­ter.

“What we have is plat­form tech­nol­o­gy that you can ap­ply to any al­lo­gene­ic (off the shelf) cell line,” says Wot­ton, “pro­gram cells to man­u­fac­ture fac­tor VI­II or IX, or man­u­fac­ture an­ti­bod­ies, with an abil­i­ty to avoid de­tec­tion of the im­mune sys­tem.”

One way to think of it, he says, is as a kind of “gene ther­a­py in a box,” able to ex­press two pro­teins with an op­tion of top­ping up the dose if need­ed lat­er.

How long will that kind of ther­a­py last? Wot­ton doesn’t know the an­swer to that yet, but he’s gam­bling that it’s years rather than months. And Eli Lil­ly, which is in­creas­ing their bet on bold re­search gam­bles, wants to come along for the ride.

This is a big deal for the cell ther­a­py field in re­gen­er­a­tive med­i­cine, as the big play­ers large­ly bowed out of the are­na years ago, sat­is­fied that they were far, far away from any com­mer­cial pro­grams. Eli Lil­ly’s re­turn, along­side a same-day move by Roche we are re­port­ing now, could be an­oth­er sign that the hype cy­cle is fi­nal­ly en­ter­ing the be­gin­ning of the end.

Tar­get­ing a Po­ten­tial Vul­ner­a­bil­i­ty of Cer­tain Can­cers with DNA Dam­age Re­sponse

Every individual’s DNA is unique, and because of this, every patient responds differently to disease and treatment. It is astonishing how four tiny building blocks of our DNA – A, T, C, G – dictate our health, disease, and how we age.

The tricky thing about DNA is that it is constantly exposed to damage by sources such as ultraviolet light, certain chemicals, toxins, and even natural biochemical processes inside our cells.¹ If ignored, DNA damage will accumulate in replicating cells, giving rise to mutations that can lead to premature aging, cancer, and other diseases.

Roivant par­lays a $450M chunk of eq­ui­ty in biotech buy­out, grab­bing a com­pu­ta­tion­al group to dri­ve dis­cov­ery work

New Roivant CEO Matt Gline has crafted an all-equity upfront deal to buy out a Boston-based biotech that has been toiling for several years now at building a supercomputing-based computational platform to design new drugs. And he’s adding it to the Erector set of science operations that are being built up to support their network of biotech subsidiaries with an eye to growing the pipeline in a play to create a new kind of pharma company.

UP­DAT­ED: Mer­ck takes a swing at the IL-2 puz­zle­box with a $1.85B play for buzzy Pan­dion and its au­toim­mune hope­fuls

When Roger Perlmutter bid farewell to Merck late last year, the drugmaker perhaps best known now for sales giant Keytruda signaled its intent to take a swing at early-stage novelty with the appointment of discovery head Dean Li. Now, Merck is signing a decent-sized check to bring an IL-2 moonshot into the fold.

Merck will shell out roughly $1.85 billion for Pandion Pharmaceuticals, a biotech hoping to gin up regulatory T cells (Tregs) to treat a range of autoimmune disorders, the drugmaker said Thursday.

Why not? Sarep­ta’s third Duchenne MD drug sails to ac­cel­er­at­ed ap­proval

Sarepta may be running into some trouble with its next-gen gene therapy approach to Duchenne muscular dystrophy. But when it comes to antisense oligonucleotides, the well-trodden regulatory path is still leading straight to an accelerated approval for casimersen, now christened Amondys 45.

We just have to wait until 2024 to find out if it works.

Amondys 45’s approval was unceremonious, compared to its two older siblings. There was no controversy within the FDA over approving a drug based on a biomarker rather than clinical benefit, setting up a powerful precedent that still haunts acting FDA commissioner Janet Woodcock as biotech insiders weighed her potential permanent appointment; no drama like the FDA issuing a stunning rejection only to reverse its decision and hand out an OK four months later, which got more complicated after the scathing complete response letter was published; no anxious tea leaf reading or heated arguments from drug developers and patient advocates who were tired of having corticosteroids as their loved ones’ only (sometimes expensive) option.

J&J ad­comm live blog: J&J faces ques­tions on old­er adults, asymp­to­matic in­fec­tion, long-term im­mu­ni­ty

The FDA adcomm has advanced to the free-for-all question stage of the hearing and, as they did for Moderna and Pfizer, committee members are raising questions about the lingering issues surrounding the vaccine.

In J&J’s case, one of those unknowns is a group of participants who appeared to respond worse to the vaccine: those over 60 with comorbidities. In that group, the vaccine was only 42% effective at stopping disease starting 28 days after vaccination.

Genen­tech plots $53M dis­cov­ery quest aimed at spark­ing a 'Holy moly' piv­ot in neu­ro R&D

Genentech has committed $53 million to back a 10-year quest aimed at going back to the drawing board to use new technology and fresh scientific insights to generate a pipeline of drugs for neurological diseases.

Roche’s big South San Francisco hub will mix it up with the scientists drawn together for the Weill Neurohub — formed in 2019 as a joint research partnership involving UCSF, Berkeley and the University of Washington — in an exploration of the field to develop new therapies for some of the toughest diseases in drug R&D: Alzheimer’s, Parkinson’s, Huntington’s, ALS and autism.

Am­gen, As­traZeneca speed to­ward fil­ing next-gen an­ti­body for asth­ma af­ter un­cork­ing full late-stage da­ta

On the hunt for a novel competitor to Sanofi and Regeneron’s Dupixent in severe asthma, Amgen and AstraZeneca posted “exciting” results from their next-gen antibody late last year. Now, the partners are showing their hands, and the results look good enough for approval.

Amgen and AstraZeneca’s tezepelumab plus standard of care cut the rate of severe asthma attacks by 56% at the one-year mark compared with SOC alone, according to full data from the Phase III NAVIGATOR study presented Friday at the virtual American Academy of Allergy, Asthma & Immunology meeting. And those significant results were consistent regardless of patients’ baseline eosinophil counts.

With dust set­tled on ac­tivist at­tack, Lau­rence Coop­er leaves Zio­pharm to a new board

Laurence Cooper has done his part.

In the five years since he left a tenured position at Houston’s MD Anderson Cancer Center to become CEO of Boston-based Ziopharm, he’s steered the small-cap immunotherapy player through patient deaths in trials, clinical holds, short attacks and, most recently, an activist attack on the board.

So when the company has “fantastic news” like an IND clearance for a TCR T cell therapy program, he’s ready to pass on the baton.
