Seat­tle Ge­net­ics gets an­oth­er drug close to the fin­ish line

Seat­tle Ge­net­ics’ pro­duc­tive streak con­tin­ues.

Af­ter clos­ing out 2019 with its sec­ond ap­proved drug  – a po­ten­tial block­buster in Pad­cev  – the ADC biotech then pre­sent­ed da­ta show­ing that Pad­cev com­bined with Keytru­da may be more ef­fec­tive than Keytru­da alone for blad­der can­cer pa­tients.

And on Thurs­day, the com­pa­ny an­nounced an­oth­er drug has been ac­cept­ed for FDA re­view and has been giv­en pri­or­i­ty sta­tus. The drug, tu­ca­tinib,  is be­ing as­sessed as part of a com­bi­na­tion treat­ment for lo­cal­ly ad­vanced or metasta­t­ic HER2-pos­i­tive breast can­cer. A PDU­FA date has been set for Au­gust 20, 2020.

The ap­pli­ca­tion to mar­ket the drug is based on pos­i­tive pro­gres­sion-free sur­vival and over­all sur­vival da­ta from a Phase II tri­al un­veiled in De­cem­ber: Pa­tients giv­en tu­ca­tinib lived about 2 months longer with­out their can­cer re­turn­ing.

Un­like the rest of Seat­tle’s pipeline, tu­ca­tinib is not an ADC, or an an­ti­body-drug con­ju­gate. Once a trendy idea, the con­cept fell most­ly out of the news for years be­fore Seat­tle Ge­net­ics’ re­cent suc­cess re­vived in­ter­est. The tech­nol­o­gy es­sen­tial­ly us­es an an­ti­body as a kind of hom­ing sys­tem to guide a cy­to­tox­ic  drug to the tu­mor site.

Rather, the drug is a se­lec­tive ty­ro­sine ki­nase in­hibitor for HER2. It did not come from in-house, but was orig­i­nal­ly de­vel­oped by Ar­ray Bio­Phar­ma, who li­censed it to Cas­ca­di­an Ther­a­peu­tics. Seat­tle Ge­net­ics bought Cas­ca­di­an for $614 mil­lion in 2018.

In ad­di­tion to tu­ca­tinib and Pad­cev, known chem­i­cal­ly as en­for­tum­ab ve­dotin, Seat­tle Ge­net­ics al­so has a Phase II ADC in col­lab­o­ra­tion with Gen­mab and a Phase II ADC in col­lab­o­ra­tion with Take­da.

Un­der fire, FDA to is­sue stricter guid­ance for Covid-19 vac­cine EUA this week — re­port

The FDA has been insisting for months that a Covid-19 vaccine had to be at least 50% effective – a measure of transparency meant to shore public trust in the agency and in a vaccine that had been brought forward at record speed and record political pressure. But now, with concerns of a Trump-driven authorization arriving before the election, the agency may be raising the bar.

The FDA is set to release new guidance that would raise safety and efficacy requirements for a vaccine EUA above earlier guidance and above the criteria used for convalescent plasma or hydroxychloroquine, The Washington Post reported. Experts say this significantly lowers the odds of an approval before the election on November 3, which Trump has promised despite vocal concerns from public health officials, and could help shore up public trust in the agency and any eventual vaccine.

Still held down by clin­i­cal hold, No­var­tis' Zol­gens­ma falls fur­ther be­hind Bio­gen and Roche as FDA asks for a new piv­otal study

Last October, the FDA slowed down Novartis’ quest to extend its gene therapy to older spinal muscular atrophy patients by slapping a partial hold on intrathecal administration. Almost a year later, the hold is still there, and regulators are adding another hurdle required for regulatory submission: a new pivotal confirmatory study.

The new requirement — which departs significantly from Novartis’ prior expectations — will likely stretch the path to registration beyond 2021, when analysts were expecting a BLA submission. That could mean more time for Biogen to reap Spinraza revenues and Roche to ramp up sales of Evrysdi in the absence of a rival.

Scoop: ARCH’s Bob Nelsen is back­ing an mR­NA up­start that promis­es to up­end the en­tire man­u­fac­tur­ing side of the glob­al busi­ness

For the past 2 years, serial entrepreneur Igor Khandros relied on a small network of friends and close insiders to supply the first millions he needed to fund a secretive project to master a new approach to manufacturing mRNA therapies.

Right now, he says, he has a working “GMP-in-a-box” prototype for a new company he’s building — after launching 3 public companies — which plans to spread this contained, precise manufacturing tech around the world with a set of partners. He’s raised $60 million, recruited some prominent experts. And not coincidentally, he’s going semi-public with this just as a small group of pioneers appears to be on the threshold of ushering in the world’s first mRNA vaccines to fight a worldwide pandemic.

Trump’s HHS claims ab­solute au­thor­i­ty over the FDA, clear­ing path to a vac­cine EUA

The top career staff at the FDA has vowed not to let politics overrule science when looking at vaccine data this fall. But Alex Azar, who happens to be their boss’s boss, apparently won’t even give them a chance to stand in the way.

In a new memorandum issued Tuesday last week, the HHS chief stripped the FDA and other health agencies under his purview of their rule making ability, asserting all such power “is reserved to the Secretary.” Sheila Kaplan of the New York Times first obtained and reported the details of the September 15 bulletin.

As its biotechs hit the pan­dem­ic ex­it, Lon­gi­tude rais­es $585M for new neu­ro, can­cer, ag­ing and or­phan-fo­cused fund

The years have been kind to Longitude Capital. This year, too.

A 2006 spinout of Pequot Capital, its founders started their new firm just four years before the parent company would go under amid insider trading allegations. Their first life sciences fund raised $325 million amid the financial crisis, they added a second for $385 million and then in, 2016, a third for $525 million. In the last few months, the pandemic biotech IPO boom netted several high-value exits from those funds, as Checkmate, Vaxcyte, Inozyme and Poseida all went public.

Gene Wang, Immetas co-founder and CEO (file photo)

Im­metas Ther­a­peu­tics nabs $11M Se­ries A to nar­row their bis­pe­cif­ic work tar­get­ing in­flam­ma­tion in age-re­lat­ed dis­eases

How does a biotech celebrate its two-year anniversary? For Immetas Therapeutics, it’s with an $11 million Series A round and a game plan to fight age-related disease.

Co-founders Gene Wang and David Sinclair came together years ago around the idea that inflammation is the ultimate process driving age-related illnesses, including cancer. The duo launched Immetas in 2018 and packed the staff with industry experts. Wang, who says he’s always had an entrepreneurial spirit, has held lead roles at Novartis, GSK, Bristol Myers Squibb and Merck. He’s worked on blockbuster drugs like Humira, Gardasil, Varubi and Zolinza. And now, he’s channeling that spirit as CEO.

Af­ter bruis­ing re­jec­tion, blue­bird and Bris­tol My­ers Squibb land ide-cel pri­or­i­ty re­view. But will it mat­ter for the CVR?

With the clock all but up, the FDA accepted and handed priority review to Bristol Myers Squibb and bluebird bio’s BCMA CAR-T, keeping a narrow window open for Celgene investors to still cash in on the $9 CVR from the $63 billion Celgene merger.

The acceptance comes five months after the two companies weres slammed with a surprise refuse-to-file that threatened to foreclose the CVR entirely. Today’s acceptance sets the FDA decision date for March 27, 2021 – or precisely 4 days before the CVR deadline of March 31. Given the breakthrough designation and strong pivotal data — 81.5% response rate, 35.2% complete response rate — priority review was largely expected.

#ES­MO20: Push­ing in­to front­line, Mer­ck and Bris­tol My­ers duke it out with new slate of GI can­cer da­ta

Having worked in parallel for years to move their respective PD-1 inhibitors up to the first-line treatment of gastrointestinal cancers, Merck and Bristol Myers Squibb finally have the data at ESMO for a showdown.

Comparing KEYNOTE-590 and CheckMate-649, of course, comes with the usual caveats. But a side-by-side look at the overall survival numbers also offer some perspective on a new frontier for the reigning checkpoint rivals, both of whom are claiming to have achieved a first.
