Blue­bird has a promis­ing new up­date on its BC­MA CAR-T for mul­ti­ple myelo­ma, but is it still the leader?

Nick Leschly / Boston Globe, End­points News


Blue­bird bio $BLUE un­veiled its lat­est up­date on its close­ly-watched BC­MA-tar­get­ing CAR-T for mul­ti­ple myelo­ma to­day of­fer­ing a slate of sol­id ev­i­dence that demon­strates the promise that at­tract­ed Cel­gene $CELG to their am­bi­tious col­lab­o­ra­tion on this drug. But with a ri­val Chi­nese group mak­ing a splash at AS­CO this year, the biotech may be see­ing its sta­tus as the fron­trun­ner in the field start to fade a bit.

In the first new da­ta to come out since late last year, blue­bird of­fered an up­date on 18 pa­tients in four dif­fer­ent dos­ing co­horts in search of in­sights on dura­bil­i­ty, dos­ing and safe­ty for bb2121.

With 18 pa­tients evalu­able for ef­fi­ca­cy, there were 15 in what blue­bird termed ac­tive dos­ing reg­i­mens above the min­i­mum for bb2121, and all of them achieved an ob­jec­tive re­sponse. Twelve achieved a very good par­tial re­sponse to com­plete re­sponse, as­so­ci­at­ed with longer sur­vival times. And of the 4 pa­tients evalu­able for min­i­mal resid­ual dis­ease sta­tus, all were MRD neg­a­tive with on­ly a few or no myelo­ma cells in cir­cu­la­tion.

That is all ex­cel­lent.

Up un­til now, blue­bird and Cel­gene were wide­ly viewed as the lead­ers in the BC­MA field. But Nan­jing Leg­end’s da­ta out this morn­ing may well put that sta­tus in ques­tion.

I asked blue­bird CEO Nick Leschly about that over the week­end.

His re­sponse, with a smile: “We are com­plete­ly, con­struc­tive­ly para­noid no mat­ter what.”

Short trans­la­tion: Blue­bird is hap­py where they are and con­fi­dent about mov­ing to next steps as their part­ner Cel­gene lays the foun­da­tion for a ground­break­ing reg­is­tra­tional study that may well get start­ed lat­er this year. But they all know it won’t be easy or free of chal­lenges — now or in the fu­ture as ri­val ther­a­pies line up to chal­lenge them.

Da­ta from tri­als that don’t in­volve head-to-head de­signs with­in the con­struct of the same study are no­to­ri­ous­ly dif­fi­cult to com­pare. In Leg­end’s case, says Leschly, it seems ev­i­dent that the pa­tients weren’t as sick and hadn’t failed the same mul­ti­ple of drugs that blue­bird re­cruit­ed for.

That makes it “ap­ples and or­anges,” he says, adding “that doesn’t mean it isn’t great da­ta.”

All of it, notes Leschly, helps val­i­date the tar­get, while blue­bird is sat­is­fied that it has the right drug to take for­ward. Its next-gen drug, bb21217, will come up be­hind it as Cel­gene preps for the piv­otal BC­MA study to some. “It’s all go, go, go” on bb2121, says Leschly, whose of­fi­cial ti­tle is chief blue­bird.

“All these pa­tients are do­ing in­cred­i­bly well,” says the CEO about his lead ther­a­py, point­ing to par­tial re­spons­es in their study that re­flect­ed a near era­sure of can­cer. These drugs face a high bar on demon­strat­ing ef­fi­ca­cy, he adds, and bb2121 comes through with fly­ing col­ors.

Blue­bird came to AS­CO with a few things to prove. It need­ed to prove that its drug works in a broad­er num­ber of pa­tients. And it need­ed to prove that the safe­ty is­sues around cy­tokine re­lease syn­drome were man­age­able.

Blue­bird’s CEO is com­ing out of AS­CO be­liev­ing that he’s an­swered those chal­lenges.

I asked Leschly about the de­bate over the 4-1BB cos­tim­u­la­to­ry do­main its drug us­es, and the the­o­ry that it could be safer than the CD28 al­ter­na­tives on the mar­ket.

Leschly’s re­mark: he’s learned to “be care­ful of open­ing your mouth be­fore you know what you’re talk­ing about.”

The 4-1BB do­main does seem to help dura­bil­i­ty, he adds, but he’s hes­i­tant to say that it ex­tends to safe­ty at this point. It’s just too ear­ly.

Blue­bird’s ex­ecs say they still have to de­cide ex­act­ly which dose to take in­to the next phase of their study (and I pressed them on it), as they add new pa­tients and pre­pare for the piv­otal study to come.

Cel­gene is clear that they want to start en­rolling for the piv­otal study this year, says Leschly. And with 50% of the US com­mer­cial rights re­sid­ing at blue­bird, he’s ready for the next step.

Norbert Bischofberger. Kronos

Backed by some of the biggest names in biotech, Nor­bert Bischof­berg­er gets his megaround for plat­form tech out of MIT

A little over a year ago when I reported on Norbert Bischofberger’s jump from the CSO job at giant Gilead to a tiny upstart called Kronos, I noted that with his connections in biotech finance, that $18 million launch round he was starting off with could just as easily have been $100 million or more.

With his first anniversary now behind him, Bischofberger has that mega-round in the bank.

Medicxi is rolling out its biggest fund ever to back Eu­rope's top 'sci­en­tists with strange ideas'

Francesco De Rubertis built Medicxi to be the kind of biotech venture player he would have liked to have known back when he was a full time scientist.

“When I was a scientist 20 years ago I would have loved Medicxi,’ the co-founder tells me. It’s the kind of place run by and for investigators, what the Medicxi partner calls “scientists with strange ideas — a platform for the drug hunter and scientific entrepreneur. That’s what I wanted when I was a scientist.”

Af­ter a decade, Vi­iV CSO John Pot­tage says it's time to step down — and he's hand­ing the job to long­time col­league Kim Smith

ViiV Healthcare has always been something unique in the global drug industry.

Owned by GlaxoSmithKline and Pfizer — with GSK in the lead as majority owner — it was created 10 years ago in a time of deep turmoil for the field as something independent of the pharma giants, but with access to lots of infrastructural support on demand. While R&D at the mother ship inside GSK was souring, a razor-focused ViiV provided a rare bright spot, challenging Gilead on a lucrative front in delivering new combinations that require fewer therapies with a more easily tolerated regimen.

They kept a massive number of people alive who would otherwise have been facing a death sentence. And they made money.

And throughout, John Pottage has been the chief scientific and chief medical officer.

Until now.

On a glob­al romp, Boehringer BD team picks up its third R&D al­liance for Ju­ly — this time fo­cused on IPF with $50M up­front

Boehringer Ingelheim’s BD team is on a global deal spree. The German pharma company just wrapped its third deal in 3 weeks, going back to Korea for its latest pipeline pact — this time focused on idiopathic pulmonary fibrosis.

They’re handing over $50 million to get their hands on BBT-877, an ATX inhibitor from Korea’s Bridge Biotherapeutics that was on display at a science conference in Dallas recently. There’s not a whole lot of data to evaluate the prospects here.

Novotech CRO Ex­pands Chi­na Team as Biotech De­mand for Clin­i­cal Tri­als In­creas­es up to 79%

An increase in demand of up to 79% for clinical trials in China has prompted Novotech the Asia-Pacific CRO to rapidly expand the China team, appointing expert local clinical executives to their Shanghai and Hong Kong offices. The company is planning to expand their team by 30% over the next quarter.

Novotech China has seen considerable demand recently which is borne out by research from GlobalData:
A global migration of clinical research is occurring from high-income countries to low and middle-income countries with emerging economies. Over the period 2017 to 2018, for example, the number of clinical trial sites opened by biotech companies in Asia-Pacific increased by 35% compared to 8% in the rest of the world, with growth as high as 79% in China.
Novotech CEO Dr John Moller said China offers the largest population in the world, rapid economic growth, and an increasing willingness by government to invest in research and development.
Novotech’s 23 years of experience working in the region means we are the ideal CRO partner for USA biotechs wanting to tap the research expertise and opportunities that China offers.
There are over 22,000 active investigators in Greater China, with about 5,000 investigators with experience on at least 3 studies (source GlobalData).

Servi­er scoots out of an­oth­er col­lab­o­ra­tion with Macro­Gen­ics, writ­ing off their $40M

Servier is walking out on a partnership with MacroGenics $MGNX — for the second time.

After the market closed on Wednesday MacroGenics put out word that Servier is severing a deal — inked close to 7 years ago — to collaborate on the development of flotetuzumab and other Dual-Affinity Re-Targeting (DART) drugs in its pipeline.

MacroGenics CEO Scott Koenig shrugged off the departure of Servier, which paid $20 million to kick off the alliance and $20 million to option flotetuzumab — putting a heavily back-ended $1 billion-plus in additional biobuck money on the table for the anti-CD123/CD3 bispecific and its companion therapies.

Den­mark's Gen­mab hits the jack­pot with $500M+ US IPO as small­er biotechs rake in a com­bined $147M

Danish drugmaker Genmab A/S is off to the races with perhaps one of the biggest biotech public listings in decades, having reaped over $500 million on the Nasdaq, as it positions itself as a bonafide player in antibody-based cancer therapies.

The company, which has long served as J&J’s $JNJ key partner on the blockbuster multiple myeloma therapy Darzalex, has asserted it has been looking to launch its own proprietary product — one it owns at least half of — by 2025.

FDA over­rides ad­comm opin­ions a fifth of the time, study finds — but why?

For drugmakers, FDA advisory panels are often an apprehended barometer of regulators’ final decisions. While the experts’ endorsement or criticism often translate directly to final outcomes, the FDA sometimes stun observers by diverging from recommendations.

A new paper out of Milbank Quarterly put a number on that trend by analyzing 376 voting meetings and subsequent actions from 2008 through 2015, confirming the general impression that regulators tend to agree with the adcomms most of the time — with discordances in only 22% of the cases.

UP­DAT­ED: With loom­ing ‘apoc­a­lypse of drug re­sis­tance,’ Mer­ck’s com­bi­na­tion an­tibi­ot­ic scores FDA ap­proval on two fronts

Merck — one of the last large biopharmaceuticals companies in the beleaguered field of antibiotic drug development — on Wednesday said the FDA had sanctioned the approval of its combination antibacterial for the treatment of complicated urinary tract and intra-abdominal infections.

To curb the rise of drug-resistant bacteria and maintain the efficacy of the therapy, Recarbrio (and other antibacterials) — the drug must be used to treat or prevent infections that are proven or strongly suspected to be caused by susceptible gram-negative bacteria, Merck $MRK said.
