Gates-backed Affini­vax grabs $10M up­front and a ma­jor league part­ner for a ground­break­ing at­tempt to beat Pfiz­er’s su­per­star vac­cine


Over the past three years Steve Brug­ger and the crew at Cam­bridge, MA-based Affini­vax have been work­ing steadi­ly on a next-gen plat­form for vac­cine de­vel­op­ment, lay­ing the ground­work — with key sup­port from the Bill & Melin­da Gates Foun­da­tion — for the first clin­i­cal tri­al of what they be­lieve can be a break­through in the vac­cines field.

This morn­ing, Brug­ger is un­veil­ing a col­lab­o­ra­tion with Astel­las, which had ear­li­er signed on to col­lab­o­rate on a very ear­ly-stage vac­cine pro­gram at the biotech. Now Astel­las has come in with $10 mil­lion to front their pact on the lead ef­fort, sign­ing off on an undis­closed set of mile­stones and roy­al­ties while agree­ing to shoul­der the full cost of the clin­i­cal pro­gram that lies ahead.

The deal cen­ters on a suc­ces­sor to Pfiz­er’s megablock­buster pneu­mo­coc­cus vac­cine Pre­vnar 13, which brought in about $6 bil­lion last year.

The biotech was or­ga­nized back in 2014 with tech de­vel­oped at Boston Chil­dren’s and a mis­sion to break clear of the con­ju­ga­tion chem­istry that lies at the heart of Pre­vnar 13.

“We do not use con­ju­ga­tion chem­istry,” Brug­ger tells me in no un­cer­tain terms. The tra­di­tion­al con­ju­ga­tion path­way of link­ing poly­sac­cha­rides to pro­teins in vac­cine de­vel­op­ment is lim­it­ing, he says. Affini­vax’s plat­form tech — the Mul­ti­ple Anti­gen Pre­sen­ta­tion Sys­tem, or MAPS — al­lows for bind­ing mul­ti­ple poly­sac­cha­rides to pro­teins. It cov­ers the use of bi­otin and rhiza­vidin tags to lock mul­ti­ple poly­sac­cha­rides and pro­teins to­geth­er so their vac­cine can cov­er a full spec­trum of 90 strains of pneu­mo­coc­cus in­stead of the 13 out­lined for Pre­vnar 13. And in­stead of us­ing the pro­teins sim­ply as a car­ri­er, Affini­vax’s pro­teins are de­signed to elic­it B and T cell re­spons­es, amp­ing up the ef­fi­ca­cy.

Back in the fall of 2015, Astel­las joined Affini­vax and ClearPath De­vel­op­ment to use the biotech’s tech­nol­o­gy to de­vel­op new vac­cines to treat noso­co­mi­al in­fec­tions. And what­ev­er the Japan­ese com­pa­ny learned along the way ap­par­ent­ly opened the door to the more ad­vanced ef­fort re­lat­ed to the Pre­vnar 13 suc­ces­sor.

“It’s a nat­ur­al fit,” says Brug­ger. “They are try­ing to es­tab­lish a big­ger foot­print in the glob­al vac­cine space.” And that leaves Astel­las open to break­ing free from the tech­nol­o­gy that has dic­tat­ed de­vel­op­ment at the dom­i­nant vac­cine play­ers.

“We’re not dis­clos­ing the time­lines,” the CEO tells me. “What I can say is that we de­clared the fi­nal de­vel­op­ment can­di­date and we’re march­ing to an IND sub­mis­sion.” And that in­cludes com­plet­ing pre­clin­i­cal stud­ies and fi­nal­iz­ing man­u­fac­tur­ing GMP plans.

Affini­vax got to this stage with­out ever rais­ing a ven­ture round. Gates has helped fi­nance their work, along with fund­ing for the noso­co­mi­al ef­fort. And now with the $10 mil­lion up­front and new lead Astel­las pro­gram they have a fund­ing source for the clin­i­cal de­vel­op­ment work and a clear path to ramp­ing up new ef­forts.

Sarep­ta was stunned by the re­jec­tion of Vyondys 53. Now it's stun­ning every­one with a sur­prise ac­cel­er­at­ed ap­proval

Sarepta has a friend in the FDA after all. Four months after the agency determined that it would be wrong to give Sarepta an accelerated approval for their Duchenne MD drug golodirsen, regulators have executed a stunning about face and offered the biotech a quick green light in any case.

It was the agency that first put out the news late Thursday, announcing that Duchenne MD patients with a mutation amenable to exon 53 skipping will now have their first targeted treatment: Vyondys 53, or golodirsen. Having secured the OK via a dispute resolution mechanism, the biotech said the new drug has been priced on par with their only other marketed drug, Exondys 51 — which for an average patient costs about $300,000 per year, but since pricing is based on weight, that sticker price can even cross $1 million.

Sarepta shares $SRPT surged 23% after-market to $124.

UP­DAT­ED: Sanofi CEO Hud­son lays out new R&D fo­cus — chop­ping di­a­betes, car­dio and slash­ing $2B-plus costs in sur­gi­cal dis­sec­tion

Earlier on Monday, new Sanofi CEO Paul Hudson baited the hook on his upcoming strategy presentation Tuesday with a tell-tale deal to buy Synthorx for $2.5 billion. That fits squarely with hints that he’s pointing the company to a bigger future in oncology, which also squares with a major industry tilt.

In a big reveal later in the day, though, Hudson offered a slate of stunners on his plans to surgically dissect and reassemble the portfoloio, saying that the company is dropping cardio and diabetes research — which covers two of its biggest franchise arenas. Sanofi missed the boat on developing new diabetes drugs, and now it’s pulling out entirely. As part of the pullback, it’s dropping efpeglenatide, their once-weekly GLP-1 injection for diabetes.

“To be out of cardiovascular and diabetes is not easy for a company like ours with an incredibly proud history,” Hudson said on a call with reporters, according to the Wall Street Journal. “As tough a choice as that is, we’re making that choice.”

Paul Biondi's track record at Bris­tol-My­ers cov­ered bil­lions in deals of every shape and size. Here's the com­plete break­down

Paul Biondi was never afraid to bet big during his stint as business development chief at Bristol-Myers Squibb. And while the gambles didn’t all pay out, by any means, his roster of pacts illustrates the broad ambitions the pharma giant has had over the last 5 years — capped by the $74 billion Celgene buyout.

On Thursday, we learned that Biondi had exited the company. And Chris Dokomajilar at DealForma came up with the complete breakdown on every buyout, licensing pact and product purchase Bristol-Myers forged during his tenure in charge of the BD team at one of the busiest companies in biopharma.

Bris­tol-My­er­s' strat­e­gy, BD chief Paul Bion­di ex­it­ed the com­pa­ny — just ahead of the $74B Cel­gene deal close

Paul Biondi, who orchestrated billions of dollars in deals for Bristol-Myers Squibb over the 5 years he’s run their business development team, has exited the company. Biondi left last month, according to a company spokesperson, in pursuit of another — unspecified — external opportunity.

After 17 years with Bristol-Myers Squibb, Paul Biondi, Head of Strategy and Business Development, decided to leave the company to pursue an external opportunity. The company wishes him well in his new endeavors. Bristol-Myers Squibb  is actively searching for Paul’s successor, and will make an announcement, as appropriate.

Bio­phar­ma has aban­doned an­tibi­ot­ic de­vel­op­ment. Here’s why we did, too.

Timing is Everything
When we launched Octagon Therapeutics in late 2017, I was convinced that the time was right for a new antibiotic discovery venture. The company was founded on impressive academic pedigree and the management team had known each other for years. Our first program was based on a compelling approach to targeting central metabolism in the most dangerous bacterial pathogens. We had already shown a high level of efficacy in animal infection models and knew our drug was safe in humans.

Shehnaaz Suli­man dives back in­to Alzheimer's at Alec­tor; Pyx­is re­cruits Spring­Works founder Lara Sul­li­van as CEO

Amid Shehnaaz Suliman’s lengthy resume it could be easy to miss her stint leading early-stage Alzheimer’s R&D at Genentech, where she oversaw a program for the ill-fated crenezumab and initiated one of the first prevention studies around the devastating neurodegenerative disease. But it is this experience that she — after thinking long and hard about her next career move over the past months — will be leaning heavily on as the first president and COO of Alector.

PhII fail­ure in rare neu­rode­gen­er­a­tive dis­ease? No mat­ter, Bio­gen will mo­tor on in Alzheimer's

Biogen’s fierce focus on disorders of the brain has hit another roadblock.

On Friday, the US drugmaker — which recently resurrected its amyloid-targeting Alzheimer’s drug, aducanumab — said its anti-tau drug, gosuranemab, failed a mid-stage study in patients with progressive supranuclear palsy (PSP), a rare brain disorder that results from deterioration of brain cells that control movement and thought.

A USP­TO le­gal ad­vis­er is off con­tro­ver­sial Gilead HIV case af­ter ac­tivists al­lege tweets show bias

Last week, a top legal adviser in the US Patent and Trademark Office working on the high-profile Gilead HIV PrEP case tweeted at Sen Bernie Sanders (I-VT) “What proof????” and then at activists “Do facts even matter to you?”

Now, STAT reports, she’s off of the case.

Activists in the coalition PrEP4All filed a petition to the USPTO on December 9 asking longtime senior legal advisor Mary Till be removed from the Gilead case, saying her tweets showed a bias toward Gilead. PrEP4All requested earlier this month the agency reject Gilead’s three-year patent extension for TAF (tenofovir alafenamide), a component of one of the HIV prevention regimens often referred to as PrEP. They allege the pharma giant delayed developing the drug in order to “game” the system and hold off generics.

What's next for Sarep­ta? A third DMD ap­proval, an­a­lysts pre­dict

What Sarepta wants, Sarepta usually gets.

In dramatic fashion on Thursday, the approval of Vyondys 53 — to treat a subset of Duchenne muscular dystrophy (DMD) patients — was unveiled, four months after the FDA’s initial rejection. With two drugs now approved on the basis of ~1% expression of dystrophin — the missing protein that causes DMD — Sarepta is in a prime position to take its third DMD drug to the regulator, analysts said, predicting healthier odds of success.
