As­traZeneca nabs pri­or­i­ty re­view for Lyn­parza in prostate as PARP in­hibitors ex­pand to more can­cers

Lyn­parza keeps rolling.

Three weeks af­ter the FDA cleared the As­traZeneca drug as a first-line treat­ment of a par­tic­u­lar form of ad­vanced pan­cre­at­ic can­cer, the agency has grant­ed pri­or­i­ty re­view for the drug as a sec­ond-line treat­ment of a par­tic­u­lar form of ad­vanced prostate can­cer. A PDU­FA date is set for the sec­ond quar­ter of 2020.

The news is an­oth­er notch in the belt for an R&D pro­gram and an on­col­o­gy pipeline that was strug­gling just three years ago. Lyn­parza, a PARP in­hibitor, and Imfinzi, As­traZeneca’s CT­LA4 im­munother­a­py, will each fin­ish 2019 with over $1 bil­lion sales, and they on­ly con­tin­ue to ex­pand their po­ten­tial mar­ket. Last week, a Lyn­parza com­bo got pri­or­i­ty re­view for a form of ad­vanced ovar­i­an can­cer and yes­ter­day an Imfinzi com­bo earned or­phan des­ig­na­tion for liv­er can­cer.

If ap­proval in ad­vanced prostate can­cer comes, it would al­so mark a step for PARP in­hibitors as a class. Orig­i­nal­ly de­vel­oped for ovar­i­an can­cers with a BR­CA mu­ta­tion, the in­hibitors have been shown ef­fec­tive in a grow­ing num­ber of can­cers. First, that meant breast can­cers with the same mu­ta­tion, but stud­ies have since shown ef­fec­tive­ness in oth­er sol­id tu­mors with the mu­ta­tion and even — for rea­sons still un­clear — some with­out it.

This in­di­ca­tion would be the sec­ond ap­proval out­side ovar­i­an or breast can­cer, af­ter last month’s ap­proval for germline BR­CA-mu­tat­ed metasta­t­ic ade­no­car­ci­no­ma of the pan­creas. The pre­cise in­di­ca­tion now be­fore the FDA is metasta­t­ic prostate can­cer with HRR mu­ta­tions — mu­ta­tions to the DNA’s re­pair process­es, in­clud­ing BR­CA — that was re­sis­tant to med­ical cas­tra­tion.

The sub­mis­sion is based on the 387-per­son, Phase III PRO­found tri­al As­traZeneca un­veiled at ES­MO. It showed that Lyn­parza ex­tend­ed the me­di­an amount of time pa­tients lived with­out their dis­ease pro­gress­ing from 3.5 months to 5.8 months. (For the BR­CA sub­set, it was 3.6 months to 7.4 months).

As­traZeneca did not an­nounce any over­all sur­vival da­ta, but the FDA does not al­ways de­mand it; Lyn­parza was ap­proved for pan­cre­at­ic can­cer de­spite show­ing no sur­vival ben­e­fit.

Mer­ck part­nered with As­traZeneca on com­mer­cial­iz­ing the drug and earns half of all prof­its.

Es­pe­ri­on's goldilocks cho­les­terol fight­er wins FDA ap­proval — will its 'tra­di­tion­al' pric­ing ap­proach spur adop­tion?

It’s more effective than decades-old statins but not as good as the injectable PCSK9 — the goldilocks treatment for cholesterol-lowering, bempedoic acid, has secured FDA approval.

Its maker, Esperion Therapeutics, is betting that their pricing strategy — a planned list price of between $10 to $11 a day — will help it skirt the pushback the PCSK9 cholesterol fighters, Repatha and Praluent, got from payers for their high sticker prices.

The sky-high expectations for the pair of PCSK9 drugs that were first approved in 2015 quickly simmered — and despite a 60% price cut, coupled with data showing the therapies also significantly cut cardiovascular risk, sales have not really perked up.

Esperion is convinced that by virtue of being a cheaper oral therapy, bempedoic acid will hit that sweet spot in terms of adoption.

“We’re kind of like the old comfortable shoe,” Esperion’s chief commercial officer Mark Glickman remarked in an interview with Endpoints News ahead of the decision date. “It’s an oral product, once-daily and nontitratable — these are things that just resonate so true with patients and physicians and I think we’ve kind of forgotten about that.”

UP­DAT­ED: A space odyssey for new an­tibi­otics: MIT's ma­chine learn­ing ap­proach

Drug development is complex, expensive and comes with lousy odds of success — but in most cases, if you make it across the finish line brandishing a product with an edge (and play your cards right) it can be a lucrative endeavor.

As it stands, the antibiotic market is cursed — it harbors the stink of multiple bankruptcies, a dearth of innovation, and is consequently barely whetting the voracious appetites of big pharma or venture capitalists. Enter artificial intelligence — the biopharma industry’s cure-all for the pesky process of making a therapeutic, including data mining, drug discovery, optimal drug delivery, and addressable patient population.

Gilead los­es two more patent chal­lenges on HIV pill, set­ting up court­room fight in Delaware

Gilead sustained two more losses in their efforts to rid themselves of an activist-backed patent lawsuit from the US government over a best-selling HIV pill.

Urged on by activists seeking to divert a portion of Gilead’s revenue to clinics and prevention programs, the Department of Health and Human Services made a claim to some of the patents for the best-selling HIV prevention drug, Truvada, also known as PrEP. Gilead responded by arguing in court that HHS’s patents were invalid.

Today, the US Patent and Trademark Office ruled that Gilead was likely to lose the last two of those challenges as well. The USPTO ruled against Gilead on the first two patents earlier this month.

Tal Zaks (Moderna via YouTube)

For two decades, a new vac­cine tech­nol­o­gy has been slow­ly ap­proach­ing prime time. Now, can it stop a pan­dem­ic?

Two months before the outbreak, Moderna CMO Tal Zaks traveled from Cambridge, MA to Washington DC to meet with Anthony Fauci and the leaders of the National Institutes of Health.

For two years, Moderna had worked closely with NIH researchers to build a new kind of vaccine for MERS, one of the deadliest new viruses to emerge in the 21st century. The program was one test for a new technology designed to be faster, cheaper and more precise than the ways vaccines had been made for over a century. They had gathered evidence the technology could work in principle, and Fauci, the longtime head of the National Institute of Allergy and Infectious Diseases and a longtime advocate for better epidemic preparedness, wanted to see if it, along with a couple of other approaches, could work in a worst-case scenario: A pandemic.

“[We were] trying to find a test case for how to demonstrate if our technology could rapidly prepare,” Zaks told Endpoints News.

Zaks and Fauci, of course, wouldn’t have to wait to develop a new test. By year’s end, an outbreak in China would short circuit the need for one and throw them into 24/7 work on a real-world emergency. They also weren’t the only ones with new technology who saw a chance to help in a crisis.

An ocean away, Lidia Oostvogels was still on vacation and relaxing at her mother’s house in Belgium when her Facebook started changing. It was days after Christmas and on most people’s feeds, the news that China had reported a novel virus to the World Health Organization blurred into the stream of holiday sweaters and fir trees. But on Oostvogels’s feed, full of vaccine researchers and virus experts, speculation boiled: There was a virus in China, something contained to the country, but “exotic,” “weird,” and maybe having to do with animals. Maybe a coronavirus.

“I was immediately thinking like, ‘Hey, this is something that if needed, we can play a role,'” Oostvogels told Endpoints.

Christos Kyratsous (via LinkedIn)

He built a MERS treat­ment in 6 months and then the best Ebo­la drug. Now Chris­tos Kyrat­sous turns his sights on Covid-19

TARRYTOWN, NY — In 2015, as the Ebola epidemic raged through swaths of West Africa, Kristen Pascal’s roommates sat her down on their couch and staged an intervention.

“Are you sure this is what you want to be doing with your life?” she recalls them asking her.

Special report

Pascal, a research associate for Regeneron, had been coming home at 2 am and leaving at 6 am. At one point, she didn’t see her roommate for a week. For months, that was life in Christos Kyratsous’ lab as the pair led a company-wide race to develop the first drug that could effectively treat Ebola before the outbreak ended. For Pascal, that was worth it.

“I’m ok, I don’t have Ebola,” Pascal told them. “I see that death toll rising and I can’t not do something about it.”

Last August, Regeneron learned they had succeeded: In a large trial across West Africa, their drug, REGN-EB3, was vastly more effective than the standard treatments. It was surprise news for the company, coming just 10 months into a trial they thought would take several years and a major victory in the global fight against a deadly virus that killed over 2,000 in 2019 and can carry a mortality rate of up to 90%.

For Kyratsous and Pascal, though, it brought only fleeting reprieve. Just four months after the NIH informed them REGN-EB3 worked, Kyratsous was back in his office reading the New York Times for updates on a new outbreak on another continent, and wondering alongside Pascal and senior management whether it was time to pull the trigger again.

In late January, as the death toll swelled and the first confirmed cases outside China broke double digits, they made a decision. Soon they were back on the phone with the multiple government agencies and their coronavirus partners at the University of Maryland’s Level 3 bio lab. The question was simple: Can Kyratsous and his team use a process honed over two previous outbreaks, and create a treatment before the newest epidemic ends? Or worse, if, as world health experts fear, it doesn’t vanish but becomes a recurrent virus like the flu?

“Christos likes things immediately,” Matt Frieman, Regeneron’s coronavirus collaborator at the University of Maryland, told Endpoints. “That’s what makes us good collaborators: We push each other to develop things faster and faster.”

The first time Regeneron tried to respond to a global outbreak, it was something of a systems test, Kyratsous explains from his office at Regeneron’s Tarrytown headquarters. Kyratsous, newly promoted, has crammed it with photos of his family, sketches of viral vectors and a shark he drew for his 3-year-old son. He speaks rapidly – an idiosyncrasy his press person says has only been aggravated this afternoon by the contents of his “Regeneron Infectious Diseases”-minted espresso glass – and he gesticulates with similar fluidity, tumbling through antibodies, MERS, the novel coronavirus, Ebola-infected monkeys.

Don't let Ab­b­Vie fool FTC with an easy di­vesti­ture, plead crit­ics in lat­est at­tack on $63B Al­ler­gan buy­out

If the FTC must let AbbVie and Allergan go ahead with their merger, at least make them divest their latest blockbuster on the market, a chorus of unions, consumer groups and public interest organizations plead in a new attempt to rein in the megamerger.

There’s a second part to their argument: If the antitrust watchdog does greenlight the divestiture AbbVie wants, then at least ensure the pharma giant cannot corner its future rivals with its exclusionary tactics.
