In­cyte flips Chi­na rights of Macro­Gen­ic­s' PD-1 to an am­bi­tious Zai Lab keen on leapfrog­ging pi­o­neers with com­bos

Amid the pro­lif­er­a­tion of check­point in­hibitors in Chi­na, Zai Lab is bring­ing in one more PD-1 agent in a move to in­stall what has be­come an es­sen­tial part of any im­muno-on­col­o­gy pipeline.

Orig­i­nal­ly de­vel­oped by Macro­Gen­ics and now con­trolled by In­cyte, IN­CM­GA0012 is in Zai Lab’s view a glob­al­ly com­pet­i­tive as­set that can stand as both a monother­a­py and com­bi­na­tion in­gre­di­ent.

“The mol­e­c­u­lar pro­file is quite sim­i­lar to Keytru­da and Op­di­vo,” said Yongjiang Hei, Zai Lab’s CSO in on­col­o­gy, on an in­vestor call.

The first com­bo Zai Lab plans to test will fea­ture mar­ge­tux­imab — a HER2 tar­get­ing drug in-li­censed from Macro­Gen­ics for $25 mil­lion up­front. Hav­ing Chi­na rights to both as­sets will al­low for smoother co­or­di­na­tion in glob­al and Chi­na stud­ies, the com­pa­ny added.

Oth­er pos­si­ble com­bos in­volve Ze­ju­la, the PARP in­hibitor from GSK’s Tesaro, in women’s can­cer as well as lung and brain can­cer. Zai Lab is al­so keen about com­bin­ing a PD-1 with the switch ki­nase in­hibitor ripretinib, for which it re­cent­ly inked a deal with De­ci­phera.

PD-1 in Chi­na is a huge mar­ket worth up to $14.2 bil­lion by 2030, Zai Lab said, and on­ly $0.1 bil­lion of that has been un­locked so far — leav­ing room for mul­ti­ple win­ners.

In­cyte — which paid $150 mil­lion up­front to bag 012 af­ter its first PD-1 from Chi­na’s Hen­grui ex­pe­ri­enced a safe­ty is­sue — grabs an im­me­di­ate $17.5 mil­lion from this deal, with de­vel­op­ment and sales mile­stones up to $60 mil­lion. The drug­mak­er is al­so re­tain­ing an op­tion to co-pro­mote with Zai Lab in Chi­na while let­ting the Chi­nese part­ner in on its on­go­ing glob­al clin­i­cal tri­als.

“To us, from a BD per­spec­tive, this is a pret­ty es­tab­lished PD-1,” CEO Saman­tha Du said, high­light­ing the tri­als that In­cyte has con­duct­ed.

No­tably, Zai Lab’s de­vel­op­ment and com­mer­cial rights cov­er both on­col­o­gy and hema­tol­ogy, though ex­ecs say they don’t cur­rent­ly have any plans on the lat­ter.

A pi­o­neer in the busi­ness of in­tro­duc­ing West­ern drugs to Chi­na and de­sign­ing clin­i­cal plans tai­lored for a do­mes­tic pa­tient pop­u­la­tion, Zai Lab has al­so been ramp­ing up in­ter­nal dis­cov­ery un­der new CSO Va­le­ria Fan­tin.

While there are no ex­ist­ing PD-1/L1 as­sets in the port­fo­lio, they might have bis­pe­cif­ic an­ti­bod­ies in­volv­ing a check­point, Du added.

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.

Covid-19 roundup: Af­ter promis­ing US its sum­mer sup­ply, Gilead in talks with EU over remde­sivir ac­cess; First in­haled remde­sivir study un­der­way

It wasn’t lost on European journalists or European doctors that the “amazing deal” the Trump Administration said it signed with Gilead to buy up remdesivir meant that they would have severely limited access to one of only two drugs proven to treat Covid-19. “This is the first major approved drug, and where is the mechanism for access?” Andrew Hill, a research fellow at Liverpool University, told The Guardian. “Once again we’re at the back of the queue.”

UP­DAT­ED: 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.

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.

FDA bars the door — for now — against Mer­ck’s star can­cer drug af­ter Roche beat them to the punch

Merck has been handed a rare setback at the FDA.

After filing for the accelerated approval of a combination of their star PD-1 drug Keytruda with Eisai’s Lenvima as a first-line treatment for unresectable hepatocellular carcinoma, the FDA nixed the move, handing out a CRL because Roche beat them to the punch on the same indication by a matter of weeks.

According to Merck:

Ahead of the Prescription Drug User Fee Act action dates of Merck’s and Eisai’s applications, another combination therapy was approved based on a randomized, controlled trial that demonstrated overall survival. Consequently, the CRL stated that Merck’s and Eisai’s applications do not provide evidence that Keytruda in combination with Lenvima represents a meaningful advantage over available therapies for the treatment of unresectable or metastatic HCC with no prior systemic therapy for advanced disease. Since the applications for KEYNOTE-524/Study 116 no longer meet the criteria for accelerated approval, both companies plan to work with the FDA to take appropriate next steps, which include conducting a well-controlled clinical trial that demonstrates substantial evidence of effectiveness and the clinical benefit of the combination.

Covid-19 roundup: Mod­er­na sticks to Ju­ly for its Phase III as ru­mors swirl; Fol­low­ing US lead, EU buys up Covid-19 treat­ments

The Phase III might be delayed from its original early July goal, but Moderna says it will still kick off the pivotal study for what could ultimately be the first Covid-19 vaccine before the end of the month.

A day after Reuters reported that squabbling between the Cambridge biotech and government regulators had held up the trial by about two weeks, Moderna released a statement saying that they had completed enrollment of their 650-person Phase II trial and were on track to begin Phase III by the end of the month. The protocol for that study, which is meant to prove whether or not the vaccine can prevent people from becoming sick, has been finalized, they said.

Mer­ck dan­gles up to $425 mil­lion to team with Flag­ship’s Foghorn Ther­a­peu­tics on drug­ging the shape of DNA

Two years after it first emerged from stealth mode, Flagship’s Foghorn Therapeutics has nabbed its first Big Pharma partner as Merck signs on to the biotech’s vision of drugging the very shape of DNA.

The deal, worth up to $425 million but with the upfront cash undisclosed, comes as Foghorn nears a pivot to a clinical stage biotech. The Cambridge-based company has added nearly 60 staffers from the 25 it had when it first emerged out of Flagship and, CEO Adrian Gottschalk said, they have finally refined the screening technology at the heart of the company, with plans to file their first IND towards the end of the year.

Sanofi doesn’t just want to be a challenger to J&J’s dominant Darzalex multiple myeloma franchise. It’s looking to pioneer a new approach by pairing its own — newly approved — anti-CD38 drug with an NK cell therapy it’s just picked up.

The French pharma giant has teed up $19.7 million (€17.5 million) upfront and close to a billion dollars (€857.5 million) in milestones for a license to Kiadis Pharma’s preclinical K-NK004 program, which consists of NK cells that have been genetically engineered not to express CD38.

Which drug de­vel­op­ers of­fer Trump a quick, game-chang­ing ‘so­lu­tion’ as the pan­dem­ic roars back? Eli Lil­ly and Ab­Cellera look to break out of the pack

We are unleashing our nation’s scientific brilliance and will likely have a therapeutic and/or vaccine solution long before the end of the year.

— Donald Trump, July 4

Next week administration officials plan to promote a new study they say shows promising results on therapeutics, the officials said. They wouldn’t describe the study in any further detail because, they said, its disclosure would be “market-moving.”

— NBC News, July 3

Something’s cooking. And it’s not just July 4 leftovers involving stale buns and uneaten hot dogs.

Over the long weekend observers picked up signs that the focus in the Trump administration may swiftly shift from the bright spotlight on vaccines being promised this fall, around the time of the election, to include drugs that could possibly keep patients out of the hospital and take the political sting out of the soaring Covid-19 numbers causing embarrassment in states that swiftly reopened — as Trump cheered along.

So far, Gilead has been the chief beneficiary of the drive on drugs, swiftly offering enough early data to get remdesivir an emergency authorization and into the hands of the US government. But their drug, while helpful in cutting stays, is known for a limited, modest effect. And that won’t tamp down on the hurricane of criticism that’s been tearing at the White House, and buffeting the president’s most stalwart core defenders as the economy suffers.

We’ve had positive early-stage vaccine data, most recently from Pfizer and BioNTech, playing catchup on an mRNA race led by Moderna — where every little sign of potential trouble is magnified into a lethal threat, just as every advance excites a frenzy of support. But that race still has months to play out, with more Phase I data due ahead of the mid-stage numbers looming ahead. A vaccine may not be available in large enough quantities until well into 2021, which is still wildly ambitious.

So what about a drug solution?

Trump’s initial support for a panacea focused on hydroxychloroquine. But that fizzled in the face of data underscoring its ineffectiveness — killing trials that aren’t likely to be restarted because of a recent population-based study offering some support. And there are a number of existing drugs being repurposed to see how they help hospitalized patients.
