Seat­tle Ge­net­ics/Astel­las win pri­or­i­ty US re­view for armed an­ti­body aimed at blad­der can­cer

Seat­tle Ge­net­ics has se­cured a speedy re­view of its sec­ond armed an­ti­body, cour­tesy of the FDA.

The com­pa­ny’s ‘break­through’ Astel­las-part­nered drug — en­for­tum­ab ve­dotin — has pro­cured pri­or­i­ty re­view from the US reg­u­la­tor, af­ter da­ta showed it helped pa­tients with a stub­born type of blad­der can­cer.

The drug-in­duced a 44% ob­jec­tive re­sponse rate (ORR) in 128 pa­tients whose dis­ease had pro­gressed de­spite treat­ment with both plat­inum-con­tain­ing chemother­a­py and a check­point in­hibitor in the one-arm EV-201 study. About 12% of the pa­tients ex­pe­ri­enced a com­plete re­sponse, Seat­tle Ge­net­ics dis­closed at AS­CO this June.

A mar­ket­ing ap­pli­ca­tion for the drug has al­ready been sub­mit­ted — and a late-stage tri­al de­signed to con­firm the drug’s safe­ty and ef­fi­ca­cy in this pa­tient pop­u­la­tion is on­go­ing.

The FDA is ex­pect­ed to make its de­ci­sion on the drug by March 15, the com­pa­ny said on Mon­day. In a note pub­lished in Ju­ly, Stifel an­a­lysts es­ti­mat­ed that en­for­tum­ab ve­dotin will gen­er­ate North Amer­i­ca sales of about $367 mil­lion in 2024.

The part­ners are test­ing the drug in com­bi­na­tion with Mer­ck’s $MRK Keytru­da and with chemother­a­py, and as part of a triplet com­bo. The idea is to al­so push for ap­proval in the front­line set­ting and gen­er­ate block­buster sales, Seat­tle Ge­net­ics’ chief Clay Sie­gall told End­points News at AS­CO.

AD­Cs are a class of ther­a­peu­tics in which a can­cer-killing tox­in is at­tached to a spe­cif­ic an­ti­body us­ing a biodegrad­able link­er. De­signed to min­i­mize the ef­fects of the chemother­a­py on healthy cells while max­i­miz­ing tu­mor cell death, the tech­nol­o­gy is some­times likened to a tro­jan horse as it is en­gi­neered to go un­no­ticed, de­liv­er­ing chemother­a­pies to cells ex­press­ing the anti­gen tar­get. Seat­tle Ge­net­ics $SGEN al­ready has one ADC on the mar­ket, Ad­cetris, and a slate of oth­ers in de­vel­op­ment.

En­for­tum­ab ve­dotin (EV) tar­gets Nectin-4, a cell ad­he­sion mol­e­cule seen in a range of sol­id tu­mors.

Urothe­lial can­cer is the most com­mon type of blad­der can­cer. About 80,470 new cas­es of blad­der can­cer are ex­pect­ed to be di­ag­nosed this year, and it is an­tic­i­pat­ed that 17,670 blad­der can­cer deaths will oc­cur in 2019, ac­cord­ing to Amer­i­can Can­cer So­ci­ety es­ti­mates. Da­ta sug­gest most pa­tients do not re­spond to check­point in­hibitors af­ter a plat­inum-con­tain­ing ther­a­py has failed as an ini­tial treat­ment for ad­vanced dis­ease, and there are no oth­er ap­proved op­tions for pa­tients once these two lines of treat­ment have been ex­haust­ed.

Bio­gen shares spike as ex­ecs com­plete a de­layed pitch for their con­tro­ver­sial Alzheimer's drug — the next move be­longs to the FDA

Biogen is stepping out onto the high wire today, reporting that the team working on the controversial Alzheimer’s drug aducanumab has now completed their submission to the FDA. And they want the agency to bless it with a priority review that would cut the agency’s decision-making time to a mere 6 months.

The news drove a 10% spike in Biogen’s stock $BIIB ahead of the bell.

Part of that spike can be attributed to a relief rally. Biogen execs rattled backers and a host of analysts earlier in the year when they unexpectedly delayed their filing to the third quarter. That delay provoked all manner of speculation after CEO Michel Vounatsos and R&D chief Al Sandrock failed to persuade influential observers that the pandemic and other factors had slowed the timeline for filing. Actually making the pitch at least satisfies skeptics that the FDA was not likely pushing back as Biogen was pushing in. From the start, Biogen execs claimed that they were doing everything in cooperation with the FDA, saying that regulators had signaled their interest in reviewing the submission.

Nick Galakatos, Blackstone global head of life sciences

Nick Galakatos and the Black­stone team now have a record $4.6B to in­vest in bio­phar­ma, with a big fo­cus on push­ing com­pa­nies over the top

Nick Galakatos and his team at Blackstone Life Sciences have seen their biggest opportunities swell up in mostly established players who don’t have all the money they need to accomplish everything on the to-do list. And right now, with the industry booming, that’s a long list with some hefty needs.

The Blackstone team has neatly tied up the largest private fund ever raised in life sciences for making big dreams come true in biopharma. Late Thursday, Blackstone put out word that they had closed their highly anticipated fund with the projected $4.6 billion all in.

OWS shifts spot­light to drugs to fight Covid-19, hand­ing Re­gen­eron $450M to be­gin large scale man­u­fac­tur­ing in the US

The US government is on a spending spree. And after committing billions to vaccines defense operations are now doling out more of the big bucks through Operation Warp Speed to back a rapid flip of a drug into the market to stop Covid-19 from ravaging patients — possibly inside of 2 months.

The beneficiary this morning is Regeneron, the big biotech engaged in a frenzied race to develop an antibody cocktail called REGN-COV2 that just started a late-stage program to prove its worth in fighting the virus. BARDA and the Department of Defense are awarding Regeneron a $450 million contract to cover bulk delivery of the cocktail starting as early as late summer, with money added for fill/finish and storage activities.

Gilead boasts of pos­i­tive remde­sivir da­ta on mor­tal­i­ty — but their analy­sis pro­vokes the skep­tics

Gilead is surging again off data that suggest its antiviral remdesivir might improve survival.

The new data come from an analysis Gilead conducted comparing the death rate and recovery time of patients in one of its remdesivir trials to a group of 800 patients “with similar baseline characteristics and disease severity” who received only standard-of-care around the same time. The result, they said, suggested that patients who received remdesivir had a 62% better chance at surviving than those who did not.

Win or lose on the mar­ket­ing OK, the FDA just gunned down GSK’s bright hopes for their BC­MA ther­a­py

The FDA’s ODAC — the Oncologic Drugs Advisory Committee — has a well-known bias in favor of adding new cancer drugs to the market, even if efficacy is at best marginal and serious safety issues demand careful management.

Doctors want as many arrows in their quiver as they can get. And when patients are dying after failing multiple drugs, why not give it a go one more time?

GlaxoSmithKline, though, is about to test out how their new BCMA antibody drug conjugate belantamab mafodotin can do after being mauled in an in-house FDA review, ahead of the Tuesday expert panel discussion. Even if the agency goes ahead with an expected green light, this drug will likely be constrained to a small niche — icing any plans they may have for making waves in oncology anytime soon.

Af­ter psilo­cy­bin and ke­t­a­mine, a new biotech comes along de­vel­op­ing a drug Scott Got­tlieb fought

Andrew Kruegel was six years into his chemistry work at Columbia University, when, one day in August 2016, he learned he might have only 30 days before the government made him destroy his research.

Kruegel had been studying kratom, a leaf long used in Southeast Asia as a stimulant or for pain. It had opioid-like properties, he found, but seemed to offer pain relief without the addictive potential or respiratory side effects of traditional opioids — a riddle that might help illuminate how human opioid receptors work.

The home run count: The $100M+ mega-round boom in biotech in­spired a $7.3B feed­ing fren­zy — so far this year

Over the last 6 months there’s been a blizzard of money piling up drifts of the green stuff through the biotech landscape. And the forecast calls for more cash windfalls ahead.

Even as a global pandemic has killed more than half a million people, blighted economies and divided nations over the proper response, it’s also helped ignite an unprecedented burst of big-time investing. And not just in Covid-19 deals, as we’ve looked at before.

An­oth­er biotech IPO set-up? Multi­na­tion­al biotech leaps from round to round, scoop­ing up cash at a blis­ter­ing pace

A short four months after announcing a $75 million haul in Series B+ fundraising, the multinational biotech Harbour BioMed pulled in another round of investments and eclipsed the nine-digit mark in the process.

Harbour completed its Series C financing, the company announced Thursday morning, raising $102.8 million and bringing its total investment sum to over $300 million since its founding in late 2016. The biotech plans to use the money to transition early-stage candidates from the discovery phase, fund candidates already in the clinic, and prep late-stage candidates for commercialization.

A new study points to $6.5B in pub­lic sup­port build­ing the sci­en­tif­ic foun­da­tion of Gilead­'s remde­sivir. Should that be re­flect­ed in the price?

By drug R&D standards, Gilead’s move to repurpose remdesivir for Covid-19 and grab an emergency use authorization was a remarkably easy, low-cost layup that required modest efficacy and a clean safety profile from just a small group of patients.

The drug OK also arrived after Gilead had paid much of the freight on getting it positioned to move fast.

In a study by Fred Ledley, director of the Center for Integration of Science and Industry at Bentley University in Waltham, MA, researchers concluded that the NIH had invested only $46.5 million in the research devoted to the drug ahead of the pandemic, a small sum compared to the more than $1 billion Gilead expected to spend getting it out this year, all on top of what it had already cost in R&D expenses.
