FDA of­fers No­var­tis a thumbs-up on En­brel biosim­i­lar as Am­gen plays of­fense/de­fense si­mul­ta­ne­ous­ly

On Fri­day, the FDA gave Am­gen a clean bill of health for its biosim­i­lar of Ab­b­Vie’s Hu­mi­ra. To­day, it’s Am­gen’s turn to watch a megablock­buster go un­der the biosim­i­lar gun, as the FDA of­fers a clear thumbs up to No­var­tis’ knock­off of the $9 bil­lion drug En­brel.

Two days ahead of a pan­el re­view, FDA in­sid­ers said that No­var­tis’ gener­ics di­vi­sion San­doz had of­fered all the da­ta need­ed to con­clude that the copy­cat was good for all in­di­ca­tions Am­gen sells En­brel for in the U.S. The FDA’s in­sid­er con­clu­sion:

“In con­sid­er­ing the to­tal­i­ty of the ev­i­dence, the da­ta sub­mit­ted by San­doz show that GP2015 is high­ly sim­i­lar to US-li­censed En­brel, notwith­stand­ing mi­nor dif­fer­ences in clin­i­cal­ly in­ac­tive com­po­nents, and that there are no clin­i­cal­ly mean­ing­ful dif­fer­ences be­tween GP2015 and US-li­censed En­brel in terms of the safe­ty, pu­ri­ty, and po­ten­cy of the prod­uct to sup­port the demon­stra­tion that GP2015 is biosim­i­lar to the US-li­censed En­brel in the stud­ied in­di­ca­tion of PsO. The Ap­pli­cant has al­so pro­vid­ed an ex­ten­sive da­ta pack­age to ad­dress the sci­en­tif­ic con­sid­er­a­tions for ex­trap­o­la­tion of da­ta to sup­port biosim­i­lar­i­ty to oth­er con­di­tions of use and po­ten­tial li­cen­sure of GP2015 for each of the in­di­ca­tions for which US-li­censed En­brel is cur­rent­ly li­censed and for which GP2015 is el­i­gi­ble for li­cen­sure.”

The de­ci­sion, which is like­ly to pave the way to a quick ap­proval, is a mir­ror re­flec­tion of the FDA’s view of Am­gen’s Hu­mi­ra biosim­i­lar, which threat­ens Ab­b­Vie’s $14 bil­lion fran­chise. But where Am­gen is fight­ing to get its biosim­i­lar on the mar­ket, it’s fight­ing tooth and nail against No­var­tis, wag­ing a le­gal war against No­var­tis’ de­vel­op­ment strat­e­gy, which stud­ied the drug on­ly for pso­ri­a­sis but is look­ing for an ap­proval on a full slate of in­di­ca­tions.

In this case, the FDA doesn’t have a prob­lem with in­di­ca­tion ex­trap­o­la­tion, as it is called, but de­pend­ing whether you’re play­ing of­fense or de­fense, it’s a flash point on the le­gal front.

These back-to-back biosim­i­lar ap­pli­ca­tions mark a new stage in the field. No­var­tis won a pi­o­neer­ing ap­proval for the first biosim­i­lar with Zarxio, a knock­off of fil­gras­tim, and has its eyes on Hu­mi­ra and oth­er ag­ing block­busters. The agency clear­ly has its doors open to these big play­ers who are threat­en­ing to top­ple some of the most lu­cra­tive drug fran­chis­es in the world. And the first wave of ap­pli­ca­tions are blaz­ing a trail for oth­ers to fol­low. But in the end, the near-term prospects for the field may be lim­it­ed if the com­pa­nies play­ing de­fense can pre­vail in the courts and pro­tect their patents for years to come.

The ju­ry is still out on that, but the FDA is mak­ing its po­si­tion crys­tal clear.

Lessons for biotech and phar­ma from a doc­tor who chased his own cure

After being struck by a rare disease as a healthy third year medical student, David Fajgenbaum began an arduous journey chasing his own cure. Amidst the hustle of this year’s JP Morgan conference, the digital trials platform Medable partnered with Endpoints Studio to share Dr. Fajgenbaum’s story with the drug development industry.

What follows is an edited transcript of the conversation between Medable CEO Dr. Michelle Longmire and Dr. Fajgenbaum, and it is full of lessons for biotech executives charged with bringing the next generation of medicines to patients.

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.

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.

UP­DAT­ED: The top 100 bio­phar­ma ven­ture in­vestors at the mega­bil­lions deal ta­ble

The VC crowd took a step back last year, but nevertheless maintained a furious pace of new investments in therapeutic tech platforms and biotech startups. And the top 100 players completely dominated the megabillions game.

Just looking at the number of deals done by each of the top 100, OrbiMed came in at the top, with 20, followed by Alexandria (18), Perceptive (16) and the ubiquitous RA Capital at 16. It’s impossible to say exactly how much they invested in total — those numbers are only rarely provided — but it is clear from the numbers assembled by Chris Dokomajilar at DealForma who’s most likely to be found sitting at the table during the go-go days of biotech investing.

Dokomajilar tracked $14.06 billion in biotech venture investing last year, a dip from the frenzied pace of $16.02 billion in 2018 and more than $10 billion higher than he recorded for 2010, as the economy was recovering from a profound economic crisis.

As sick­le cell pa­tients find new op­tions, NEA-found­ed Imara pitch­es mid-stage al­ter­na­tive for $86M IPO

November 2019 proved to be a fruitful month for patients with blood disorders known as hemoglobinopathies. Within days, the FDA ushered two drugs for sickle cell disease and another for beta thalassemia to the market — livening up a barren field.

Imara, a relatively young plower, is riding on that enthusiasm as it shoots for an $86.25 million IPO.

Imara emerged from New Enterprise Associates’ orphan drug accelerator Cydan in 2016 as a single-product company. $77.3 million in private financing later IMR-687 remains the sole asset in its pipeline; the difference is the drug is now in Phase II for sickle cell disease, with topline data slated for later this year and two other mid-stage beta thalassemia studies lined up.

UP­DAT­ED: RA joins glob­al syn­di­cate to back a $98M round for CAN­bridge

A Beijing-based rare disease and oncology player has raised $98 million to help fund the expansion of its pipeline as well as a commercial portfolio.

CANbridge put out word Tuesday that the global private equity player General Atlantic joined forces with Chinese CRO Wuxi AppTec to lead the Series D, with both ready to chip in an extra $10 million each under the right conditions. The syndicate includes RA Capital Management, Hudson Bay Capital Management, YuanMing Prudence Fund and Tigermed.

UP­DAT­ED: Drug dis­cov­ery in HD: Ox­ford spin­of­f's mass spec­trom­e­try ap­proach scores fresh fund­ing

The technology used to detect explosives at airports — mass spectrometry — is being piloted as an engine for drug discovery.

Mass spectrometry is a tool designed to measure with profound accuracy the mass of a single molecule. Typically, mass spectrometers can be used to identify unknown compounds, to quantify known compounds, and to determine the structure and chemical properties of molecules.

The list of the 11 block­busters-to-be in line for a 2020 launch high­light agony and ec­sta­sy of drug R&D

For all the talk about unmet medical need and patients first and so on, the key criteria investors watch for any new drug in the pipelines is peak sales projection. Are you going to hit the blockbuster mark, at $1 billion-plus, or are you going to be an also-ran in the sales department?

Of course, analysts’ peak sales projections by themselves are of limited value in many cases. When the PCSK9 drugs started arriving 5 years ago, Repatha was billed as a $2.5 billion peak earner. They’re nowhere near that, with new competition threatening current levels. And if Biogen’s controversial Alzheimer’s drug aducanumab (submission planned but not on the list) is approved, per chance, will payers cover it?

Maybe not. And then those $10 billion in peak sales assumptions would go straight down the drain.

But, analysts are analysts, and peak sales projections have to be factored in when assessing the top experimental drugs up for a launch in the year ahead.

UP­DAT­ED: Chi­na ap­proves flu drug be­ing tout­ed as a po­ten­tial coro­n­avirus treat­ment amid a rush of clin­i­cal stud­ies

One of the three drugs that China’s Ministry of Science and Technology has tapped as potential COVID-19 treatments to watch has notched its first Chinese OK — for the flu.

While there’s no proof yet that fapilavir, or favipiravir, is the cure that patients and physicians are yearning for, it stands out for a unique constellation of qualities. It’s been commercially available in Japan for several years (unlike Gilead’s experimental remdesivir) yet it’s new to China (unlike the malaria drug chloroquine phosphate). Perhaps more importantly, a domestic biotech — Zhejiang Hisun Pharma — owns the rights to manufacture and market the drug, preempting any concerns about patents.

FDA goes on high alert as coro­n­avirus rais­es threat to drug man­u­fac­tur­ing and clin­i­cal tri­als grind to a halt

The FDA isn’t quite sure just what the coronavirus outbreak in China will mean for the US pharma industry, but it has the potential to trigger a host of troublesome issues around the supply chain the country is directly plugged into.
