Philip­pine health of­fi­cials or­der Sanofi to halt Deng­vax­ia sales as con­tro­ver­sy over health threat swells

Philip­pine health of­fi­cials have or­dered Sanofi to jerk its dengue vac­cine off the mar­ket as the con­tro­ver­sy over the health threat it pos­es to chil­dren con­tin­ues to roil the coun­try.

The Philip­pines was the first coun­try to launch a ma­jor vac­ci­na­tion cam­paign with Deng­vax­ia, the world’s first dengue vac­cine. But last week Sanofi con­ced­ed some­thing that two ex­pert groups had con­clud­ed in­de­pen­dent­ly just as the coun­try was rolling out its $70 mil­lion ef­fort ear­ly last year. The vac­cine, giv­en to any­one who had not al­ready been in­fect­ed, left peo­ple vul­ner­a­ble to se­vere, life-threat­en­ing dengue in the event they were sub­se­quent­ly in­fect­ed by wild type dengue.

Both in­de­pen­dent stud­ies in Vac­cine and Sci­ence con­clud­ed that Sanofi’s own tri­al da­ta on se­vere in­fec­tions among 2-to-5 year olds of­fered am­ple warn­ing of the health threat Sanofi fi­nal­ly con­ced­ed.

Health of­fi­cials say they vac­ci­nat­ed 730,000 chil­dren in the Philip­pines, 9 and up.

Sanofi’s health warn­ing last week sug­gest­ed on­ly that the vac­cine la­bel be changed to urge health of­fi­cials to de­ter­mine the like­li­hood that some­one had been pre­vi­ous­ly in­fect­ed be­fore vac­ci­nat­ing them.

Sanofi of­fi­cials have down­played the threat, say­ing on­ly a small frac­tion of the chil­dren vac­ci­nat­ed face the threat of he­m­or­rhag­ic fever. This is al­so a vac­cine in­tend­ed for mil­lions of peo­ple around the world, and the safe­ty bar is typ­i­cal­ly set high.

Brazil­ian of­fi­cials, mean­while, say that they’ve re­strict­ed the use of the vac­cine in the wake of the dis­clo­sure by Sanofi. And the EMA, which has the vac­cine un­der re­view now, tells me that reg­u­la­tors will take in­to ac­count “any emerg­ing da­ta” in com­plet­ing its as­sess­ment.

Sanofi spent $1.8 bil­lion over more than 20 years to prep this launch, ex­pect­ing to de­vel­op a new fran­chise worth $1.5 bil­lion a year. But not­ed dengue ex­pert Scott Hal­stead — who has spent decades in the field — says that Sanofi’s re­searchers nev­er ful­ly learned the bi­ol­o­gy of the dis­ease they were try­ing to erad­i­cate, point­ing them straight to the cri­sis they’re in now.

Pris­on­er #87850-053 does not get to add drug de­vel­op­er to his list of cred­its

Just days after Retrophin shed its last ties to founder Martin Shkreli, the biotech is reporting that the lead drug he co-invented flopped in a pivotal trial. Fosmetpantotenate flunked both the primary and key secondary endpoints in a placebo-controlled trial for a rare disease called pantothenate kinase-associated neurodegeneration, or PKAN.

Hal Barron. GSK

GSK's Hal Bar­ron her­alds their sec­ond pos­i­tive PhI­II for cru­cial an­ti-BC­MA ther­a­py, point­ing to a push for quick OKs in a crowd­ed field

Hal Barron has his second positive round of Phase III data in hand for his anti-BCMA antibody drug conjugate belantamab mafodotin (GSK2857916). And GSK’s research chief says the data paves the way for their drive in search of an FDA approval for treating multiple myeloma. 

It’s hard to overestimate the importance of this drug for GSK, a cornerstone of Barron’s campaign to make a dramatic impact on the oncology market and provide some long-lost excitement for the pharma giant’s pipeline. They’re putting this BCMA program at the front of that charge — looking to lead a host of rivals all aimed at the same target.

UP­DAT­ED: An em­bold­ened As­traZeneca splurges $95M on a pri­or­i­ty re­view vouch­er. Where do they need the FDA to hus­tle up?

AstraZeneca is in a hurry.

We learned this morning that the pharma giant — not known as a big spender, until recently — forked over $95 million to get its hands on a priority review voucher from Sobi, otherwise known as Swedish Orphan Biovitrum.

That marks another step down on price for a PRV, which allows the holder to slash 4 months off of any FDA review time.

We­bi­nar: Re­al World End­points — the brave new world com­ing in build­ing fran­chise ther­a­pies

Several biopharma companies have been working on expanding drug labels through the use of real world endpoints, combing through the data to find evidence of a drug’s efficacy for particular indications. But we’ve just begun. Real World Evidence is becoming an important part of every clinical development plan, in the soup-through-nuts approach used in building franchises.

I’ve recruited a panel of 3 top experts in the field — the first in a series of premium webinars — to look at the practical realities governing what can be done today, and where this is headed over the next few years, at the prodding of the FDA.

ZHEN SU — Merck Serono’s Senior Vice President and Global Head of Oncology
ELLIOTT LEVY — Amgen’s Senior Vice President of Global Development
CHRIS BOSHOFF — Pfizer Oncology’s Chief Development Officer

AveX­is sci­en­tif­ic founder fires back at No­var­tis CEO Vas Narasimhan, 'cat­e­gor­i­cal­ly de­nies any wrong­do­ing'

Brian Kaspar’s head was among the first to roll at Novartis after company execs became aware of the fact that manipulated data had been included in its application for Zolgensma, now the world’s most expensive therapy.

But in his first public response, the scientific founder at AveXis — acquired by Novartis for $8.7 billion — is firing back. And he says that not only was he not involved in any wrongdoing, he’s ready to defend his name as needed.

I reached out to Brian Kaspar after Novartis put out word that he and his brother Allen had been axed in mid-May, two months after the company became aware of the allegations related to manipulated data. His response came back through his attorneys.

Bob Smith, Pfizer

Pfiz­er is mak­ing a $500M state­ment to­day: Here’s how you be­come a lead play­er in the boom­ing gene ther­a­py sec­tor

Three years ago, Pfizer anted up $150 million in cash to buy Bamboo Therapeutics in Chapel Hill, NC as it cautiously stuck a toe in the small gene therapy pool of research and development.

Company execs followed up a year later with a $100 million expansion of the manufacturing operations they picked up in that deal for the UNC spinout, which came with $495 million in milestones.

And now they’re really going for it.

Video: Putting the AI in R&D — with Badhri Srini­vasan, Tony Wood, Rosana Kapeller, Hugo Ceule­mans, Saurabh Sa­ha and Shoibal Dat­ta

During BIO this year, I had a chance to moderate a panel among some of the top tech experts in biopharma on their real-world use of artificial intelligence in R&D. There’s been a lot said about the potential of AI, but I wanted to explore more about what some of the larger players are actually doing with this technology today, and how they see it advancing in the future. It was a fascinating exchange, which you can see here. The transcript has been edited for brevity and clarity. — John Carroll

UP­DAT­ED: As­traZeneca’s Imfinzi/treme com­bo strikes out — again — in lung can­cer. Is it time for last rites?

AstraZeneca bet big on the future of their PD-L1 Imfinzi combined with the experimental CTLA-4 drug tremelimumab. But once again it’s gone down to defeat in a major Phase III study — while adding damage to the theory involving targeting cancer with a high tumor mutational burden.

Early Wednesday the pharma giant announced that their NEPTUNE study had failed, with the combination unable to beat standard chemo at overall survival in high TMB cases of advanced non-small cell lung cancer. We won’t get hard data until later in the year, but the drumbeat of failures will call into question what — if any — future this combination can have left.

Am­gen, Al­ler­gan biosim­i­lar of Roche's block­buster Rit­ux­an clears an­oth­er US piv­otal study 

Novartis $NVS may have given up, but Amgen $AMGN and Allergan $AGN are plowing ahead with their knockoff of Roche’s blockbuster biologic Rituxan in the United States.

Their copycat, ABP 798, was found to have a clinically equivalent impact as Rituxan — meeting the main goal of the study involving CD20-positive B-cell non-Hodgkin’s lymphoma patients. This is the second trial supporting the profile of the biosimilar. In January, it came through with positive PK results in patients with rheumatoid arthritis.
