Re­gen­eron to seek EUA for low­er dose of Covid-19 mAb cock­tail as new tri­al shows ma­jor drop in risk of hos­pi­tal­iza­tion or death

The suc­cess of mon­o­clon­al an­ti­body (mAb) cock­tails in keep­ing peo­ple with Covid-19 out of the hos­pi­tal con­tin­ued Tues­day, with Re­gen­eron an­nounc­ing that even a low­er-than-au­tho­rized dose of its com­bi­na­tion of mAbs re­duced hos­pi­tal­iza­tion or death by 70% in non-hos­pi­tal­ized Covid-19 pa­tients.

“We will rapid­ly dis­cuss the new da­ta with reg­u­la­to­ry au­thor­i­ties and re­quest that the 1,200 mg dose be added to the U.S. Emer­gency Use Au­tho­riza­tion, in or­der for the an­tic­i­pat­ed RE­GEN-COV sup­ply to be avail­able to treat even more pa­tients,” George Yan­copou­los, pres­i­dent and CSO of Re­gen­eron, said in a state­ment.

The place­bo-con­trolled tri­al of more than 4,500 peo­ple showed how casiriv­imab and imde­vimab re­duced the risk of hos­pi­tal­iza­tion or death by 70% for the 1,200 mg IV dose, and 71% for the au­tho­rized 2,400 mg IV ver­sion, when com­pared to place­bo, the com­pa­ny said.

In ad­di­tion, Re­gen­eron said a dose-rang­ing Phase II tri­al of 815 non-hos­pi­tal­ized Covid-19 pa­tients showed “sig­nif­i­cant and com­pa­ra­ble vi­ral re­duc­tions” for all dos­es test­ed of the mAb com­bo, in­clud­ing as low as 300 mg. A com­pa­ny spokesper­son said fur­ther dis­cus­sions with the FDA will be nec­es­sary to dis­cuss sub­cu­ta­neous ad­min­is­tra­tion, and “even low­er dose pos­si­bil­i­ties in the fu­ture.”

Walid Gel­lad

Walid Gel­lad, di­rec­tor of the Uni­ver­si­ty of Pitts­burgh Cen­ter for Phar­ma­ceu­ti­cal Pol­i­cy and Pre­scrib­ing, who’s un­af­fil­i­at­ed with the re­sults, said that they show yet an­oth­er ex­am­ple of how ef­fec­tive these mAbs are for out­pa­tient use to re­duce hos­pi­tal­iza­tion.

“Com­pa­nies in a pan­dem­ic should be ap­plaud­ed for test­ing low­er dos­es, which will ex­tend sup­ply,” he added.

De­spite the pos­i­tive new da­ta, dos­es of the Re­gen­eron and Eli Lil­ly mAb cock­tails have been dif­fi­cult to come by and states have had to grap­ple with fig­ur­ing out new ways to ad­min­is­ter the in­fu­sions.

A Re­gen­eron spokesper­son said the com­pa­ny so far has de­liv­ered near­ly 300,000 dos­es to the US (al­though the gov­ern­ment’s web­site still says it’s dis­trib­uted about 150,000 as of ear­ly Feb­ru­ary). Be­gin­ning in April, Re­gen­eron will de­liv­er sup­plies of the mAb cock­tail un­der its sec­ond con­tract with the US gov­ern­ment, which will pro­vide 750,000 or more dos­es by mid-year.

“Most re­cent­ly we have said we ex­pect to pro­vide ap­prox­i­mate­ly 750,000 dos­es at the 2,400 mg dose lev­el by June 30, but now we an­tic­i­pate be­ing able to pro­vide more if the 1,200 mg dose is added to the EUA,” the spokesper­son added.

Qual­i­ty Con­trol in Cell and Gene Ther­a­py – What’s Re­al­ly at Stake?

In early 2021, Bluebird Bio was forced to suspend clinical trials of its gene therapy for sickle cell disease after two patients in the trial developed cancer. As company scientists rushed to assess whether there was any causal link between the therapy and the cancer cases, Bluebird’s stock value plummeted – as did those of multiple other biopharma companies developing similar therapies.

While investigations concluded that the gene therapy was unlikely to have caused cancer, investors and the public may be more skittish regarding the safety of gene and cell therapies after this episode. This recent example highlights how delicate the fields of cell and gene therapy remain today, even as they show great promise.

Law pro­fes­sors call for FDA to dis­close all safe­ty and ef­fi­ca­cy da­ta for drugs

Back in early 2018 when Scott Gottlieb led the FDA, there was a moment when the agency seemed poised to release redacted complete response letters and other previously undisclosed data. But that initiative never gained steam.

Now, a growing chorus of researchers are finding that a dearth of public data on clinical trials and pharmaceuticals means industry and the FDA cannot be held accountable, two law professors from Yale and New York University write in an article published Wednesday in the California Law Review.

As fears mount over J&J and As­traZeneca, No­vavax en­ters a shaky spot­light

As concerns rise around the J&J and AstraZeneca vaccines, global attention is increasingly turning to the little, 33-year-old, productless, bankruptcy-flirting biotech that could: Novavax.

In the now 16-month race to develop and deploy Covid-19 vaccines, Novavax has at times seemed like the pandemic’s most unsuspecting frontrunner and at times like an overhyped also-ran. Although they started the pandemic with only enough cash to last 6 months, they leveraged old connections and believers into $2 billion and emerged last summer with data experts said surpassed Pfizer and Moderna. They unveiled plans to quickly scale to 2 billion doses. Then they couldn’t even make enough material to run their US trial and watched four other companies beat them to the finish line.

FDA of­fers scathing re­view of Emer­gent plan­t's san­i­tary con­di­tions, em­ploy­ee train­ing af­ter halt­ing pro­duc­tion

The FDA wrapped up its inspection of Emergent’s troubled vaccine manufacturing plant in Baltimore on Tuesday, after halting production there on Monday. By Wednesday morning, the agency already released a series of scathing observations on the cross contamination, sanitary issues and lack of staff training that caused the contract manufacturer to dispose of millions of AstraZeneca and J&J vaccine doses.

Ver­sant pulls the wraps off of near­ly $1B in 3 new funds out to build the next fleet of biotech star­tups. And this new gen­er­a­tion is built for speed

Brad Bolzon has an apology to offer by way of introducing a set of 3 new funds that together pack a $950 million wallop in new biotech creation and growth.

“I want to apologize,” says the Versant chairman and managing partner, laughing a little in the intro, “that we don’t have anything fancy or flashy to tell you about our new fund. Same team, around the same amount of capital, same investment strategy. If it ain’t broke, don’t fix it.”

But then there’s the flip side, where everything has changed. Or at least speeded into a relative blur. Here’s Bolzon:

Glax­o­SmithK­line hus­tles the 7th PD-1 past the fin­ish line with Jem­per­li. But how big will up­take be?

Everything came up sevens for GlaxoSmithKline on Thursday as the pharma notched the seventh PD-1 approval seven years after the first such drugs were OK’ed in Keytruda and Opdivo. But will it bring GSK good fortune?

The FDA granted accelerated approval to dostarlimab, to be branded Jemperli, to treat recurrent or advanced endometrial cancer in a specific subset of patients following platinum-based chemo. It’s a drug that came to GSK through its buyout of Tesaro, which it snapped up for $5.1 billion back in December 2018.

Bio­phar­ma ramps up lob­by­ing spend as drug pric­ing leg­is­la­tion nears

The top biopharma companies in the world collectively spent more than $40 million in just the first quarter of 2021 on lobbying Congress as part of preparations to stave off major drug pricing legislation that’s expected later this year.

Although the numbers are not dramatically higher than what the companies collectively spent in the first quarter of 2020, some like GlaxoSmithKline, Teva, Merck and Johnson & Johnson have already increased their quarterly lobbying spend in 2021 by about $1 million more each when compared to recent quarters in 2020.

House De­moc­rats call on Emer­gent ex­ecs to tes­ti­fy on qual­i­ty is­sues next month

The House Oversight Committee is investigating Covid-19 vaccine producer Emergent BioSolutions, which secured a $628 million US government contract to make AstraZeneca and J&J vaccines despite “a long, documented history” of quality control issues, Democrats said in a letter to the contract manufacturer’s executives.

Emergent’s Baltimore plant, which was shuttered on Monday by FDA, has been embroiled in controversy after being forced to destroy millions of AstraZeneca and J&J doses due to an ingredient mix-up and possible contamination.

Sen­a­tors to NIH: Do more to pro­tect US bio­med­ical re­search from for­eign in­flu­ence

Although Thursday’s Senate health committee hearing was focused on how foreign countries and adversaries might be trying to steal or negatively influence biomedical research in the US, the only country mentioned by the senators and expert witnesses was China.

Committee chair Patty Murray (D-WA) made clear in her opening remarks that the US cannot “let the few instances of bad actors” overshadow the hard work of the many immigrant researchers in the US, many of which have won Nobel prizes for their work. But she also said, “There is more the NIH can be doing here.”
