Hous­ing As­traZeneca's old R&D ef­forts in an­tibi­otics, En­ta­sis files for $86M IPO

When As­traZeneca spun out its strug­gling an­tibi­otics unit a few years back, the tech — and a much small­er team — was de­posit­ed in­to a com­pa­ny called En­ta­sis. Now, that up­start has filed for an $86 mil­lion IPO to push a few of its prod­uct can­di­dates through hu­man tri­als.

The tiny Waltham com­pa­ny is on­ly a frac­tion of what the phar­ma gi­ant’s an­tibi­otics ef­fort used to be. At one point, the unit had 175 staffers. But it was pared down over the years un­til En­ta­sis launched in 2015 with on­ly 21 em­ploy­ees. To­day, ac­cord­ing to its prospec­tus, it em­ploys 34.

En­ta­sis has a pipeline of clin­i­cal-stage prod­uct can­di­dates meant to treat in­fec­tions caused by mul­ti-drug re­sis­tant Gram-neg­a­tive bac­te­ria. Its lead prod­uct, ETX2514, in­hibits one of the most com­mon forms of bac­te­r­i­al re­sis­tance: b-lac­ta­mase en­zymes, so named be­cause of their abil­i­ty to in­ac­ti­vate b-lac­tam an­tibi­otics, one of the most com­mon­ly used class­es of an­tibi­otics. En­ta­sis has an­oth­er pipeline ther­a­py, ETX0282, that in­hibits the same en­zymes.

“By block­ing this re­sis­tance mech­a­nism, these prod­uct can­di­dates, when ad­min­is­tered in com­bi­na­tion with b-lac­tam an­tibi­otics, are de­signed to re­store the ef­fi­ca­cy of those an­tibi­otics,” the com­pa­ny said in its prospec­tus.

En­ta­sis plans to use its IPO funds to ad­vance ETX2514 through a Phase III tri­al, and to move 0282 through a mul­ti-part Phase I. The rest of the cash will go to­ward oth­er R&D and gen­er­al cor­po­rate pur­pos­es.

The com­pa­ny will list on the Nas­daq un­der the tick­er sym­bol $ET­TX.

The an­tibi­otics R&D field has been rife with hur­dles, and new­com­ers like Za­vante and Cidara have failed to make big waves like once hoped. In fact, Za­vante fiz­zled in­to an ac­qui­si­tion less than three years af­ter its launch. And Cidara suf­fered a Phase II tri­al flop last year that dropped its stock price about 50%. And al­though fed­er­al in­cen­tives have spurred new ac­tiv­i­ty in the field, the small mar­gins that dis­cour­aged de­vel­op­ment ef­forts a decade ago — lead­ing to our cur­rent crit­i­cal short­age — still ham­per the niche.

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.

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. 

As­traZeneca's di­a­betes drug Farx­i­ga helps pa­tients with heart dis­ease and with­out di­a­betes in land­mark tri­al

Months ago, data on J&J’s $JNJ Invokana indicated the diabetes drug conferred cardiovascular (CV) benefit in patients who do and do not have preexisting CV disease. On Tuesday, AstraZeneca’s $AZN rival treatment, Farxiga, was shown to cut the risk of CV death or the worsening of heart failure in patients with heart disease, in a landmark trial.

The treatments, in addition to Jardiance from Eli Lilly $LLY, belong to a class of diabetes drugs called sodium-glucose co-transporter 2 (SGLT2) inhibitors, which work by curbing the absorption of glucose via the kidneys so that surplus glucose is excreted through urination.
