GSK toss­es a trio of clin­i­cal-stage drugs on tri­al fail­ures, win­now­ing out its res­pi­ra­to­ry pipeline as can­cer moves to cen­ter stage

Glax­o­SmithK­line is sweep­ing out three of its clin­i­cal stage pro­grams as it con­tin­ues to win­now out the weak from the strong in the pipeline. And there’s no sur­prise to see that res­pi­ra­to­ry is tak­ing the big hit here.

The phar­ma gi­ant’s Q3 roundup in­clud­ed taps for a trio of drugs fol­low­ing a re­assess­ment of their chances. Thrown in­to the scrap heap are:

  • Danir­ix­in (GSK1325756), which didn’t get past a Phase IIb tri­al for COPD in Oc­to­ber. “This in­ter­im analy­sis showed danir­ix­in did not achieve the pri­ma­ry ef­fi­ca­cy end­point and this has changed the un­der­stand­ing of the risk/ben­e­fit pro­file of this as­set in COPD. Based on these da­ta GSK has tak­en the de­ci­sion to stop de­vel­op­ment in COPD.”
  • TR­PV4 (GSK2798745) — called on fu­til­i­ty dur­ing a mid-stage study in chron­ic cough. They’ll keep an ear­ly-stage pro­gram for acute res­pi­ra­to­ry dis­tress syn­drom.
  • TLR7 (GSK2245035). The drug flopped in a Phase II study for mild asth­ma, so out it goes. 
Hal Bar­ron

R&D chief Hal Bar­ron has pledged to clean up af­ter the fail­ures as quick­ly as pos­si­ble, vow­ing that a fast-fail ap­proach is his best bet to achiev­ing a turn­around in phar­ma R&D.

Iron­i­cal­ly, though, those weren’t the on­ly tri­al fail­ures that blight­ed pipeline prospects at GSK re­cent­ly. The phar­ma gi­ant’s GM-CSF drug failed the pri­ma­ry end­point for rheuma­toid arthri­tis, but com­pa­ny ex­ecs in­sist that it still has re­al po­ten­tial, with plans to car­ry it in­to Phase III. 

Bar­ron cit­ed this drug as one of the com­pa­ny’s top prospects in a weak pipeline. When I met with him in Lon­don a cou­ple of weeks ago, he out­lined a pipeline with 22 mid-stage drugs in it, an­tic­i­pat­ing that 75% of them wouldn’t make it to the next round. In just three months, four of them met with a ma­jor clin­i­cal set­back. So he’s well on his way to a high fail­ure rate.

With more drugs on the scrap heap or un­der scruti­ny fol­low­ing a clear set­back in the clin­ic, you can ex­pect to see the pres­sure grow on Bar­ron’s team to start do­ing deals to beef up the late-stage pipeline, where it’s a weak­ling.

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.

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.

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.

UP­DAT­ED: Pay­back? An­a­lysts say Sarep­ta was blind­sided by an FDA re­jec­tion dri­ven by reg­u­la­to­ry re­venge

In one of the least anticipated moves of the year, the FDA has rejected Sarepta’s application for an accelerated approval of its Duchenne MD drug golodirsen after fretting over safety issues.

In a statement that arrived after the bell on Monday, Sarepta explained the CRL, saying:

Af­ter a posse of Wall Street an­a­lysts pre­dict a like­ly new win for Sarep­ta, we're down to the wire on a crit­i­cal FDA de­ci­sion

As Bloomberg notes, most of the Wall Street analysts that cover Sarepta $SRPT are an upbeat bunch, ready to cheer on the team when it comes to their Duchenne MD drugs, or offer explanations when an odd setback occurs — as happened recently with a safety signal that was ‘erroneously’ reported last week.

FDA de­ci­sion on Ver­tex's CF triple will come just ahead of planned CEO shake­up

Vertex has clinched a priority review for the all-important cystic fibrosis triple that will blaze the trail for treating a large group of patients unhelped by its current drugs.

FDA regulators have set a PDUFA date of March 19, 2020, just a year after the Boston biotech posted positive Phase III results showing that people with two F508del mutations experienced statistically significant improvements in lung function after a 4-week regimen of VX-445, tezacaftor and ivacaftor. After reviewing 24-week data among patients with one F508del mutation and one minimal function mutation — and thoroughly comparing the VX-445 triple with another combo featuring VX-659 on scores like safety, drug-drug interactions, and photosensitivity — Vertex ultimately went with VX-445.

An MIT spin­out kills one of its ‘liv­ing ther­a­peu­tics’ af­ter flunk­ing an ear­ly-stage study — shares rout­ed

Just a few weeks after bagging $80 million in a deal to collaborate with Gingko Bioworks on its special blend of engineered bacteria used for “living therapeutics,” little Synlogic in Boston $SYBX is tossing one of its two clinical programs after watching an early-stage study go down in defeat.

Their Phase Ib/IIa study for SYNB1020 to counter the accumulation of ammonia in the body, a condition called hyperammonemia or urea cycle disorder, floundered at the interim readout, forcing the biotech to kill it and reserve its cash for pipeline therapies with greater potential.

Elan­co to buy Bay­er's an­i­mal health busi­ness for $7.6B, as deal­mak­ing gath­ers steam in the sec­tor

Last week, Elanco explicitly dodged answering questions about its rumored interest in Bayer’s animal health business in its post-earnings call. On Tuesday, the Eli Lilly spinoff disclosed it was purchasing the German drug maker’s veterinary unit in a cash-and-stock deal worth $7.6 billion. 

Elanco $ELAN has been busy on the deal-making front. In April, it laid out plans to swallow its partner, Kansas-based pet therapeutics company Aratana $PETX. A July report by Reuters suggested a potential Bayer deal was being explored, and Bloomberg last week said the deal was imminent, citing sources.
