Bris­tol-My­ers is mak­ing a bee-line to the FDA with pos­i­tive liso-cel da­ta — but is it too late in the CAR-T game?

Bris­tol-My­ers Squibb came to ASH this past week­end with a va­ri­ety of mes­sages on the new can­cer drugs they had ac­quired in the big Cel­gene buy­out, in­clud­ing liso-cel, the lead CAR-T pro­gram picked up in the $9 bil­lion Juno ac­qui­si­tion. And one of the most im­por­tant was that they had the piv­otal ef­fi­ca­cy and safe­ty da­ta need­ed to snag an ap­proval from the FDA next year, with the BLA on track for a fil­ing this month.

Pro­vid­ed there are no sna­fus or even mod­est stum­bles now, they should get an OK with­in the 2020 time­line lined out in their $9 CVR for Cel­gene — the first in a tri­fec­ta of ap­provals re­quired for a pay­out.

Whether they can go on to make it in­to a vi­able com­mer­cial ther­a­py, though, is a whole oth­er thing.

At first glance, there isn’t any­thing about the safe­ty and ef­fi­ca­cy da­ta that would force a CRL or de­lay. In a large tri­al of pa­tients with re­lapsed/re­frac­to­ry large B-cell lym­phomas in­ves­ti­ga­tors tracked an out­stand­ing 73% re­sponse rate and 53% com­plete re­sponse rate in heav­i­ly pre­treat­ed pa­tients with few op­tions.

That’s in line with Yescar­ta from Gilead’s Kite, which snagged an ap­proval more than 2 years ago, just af­ter No­var­tis’ Kym­ri­ah came through.

Then there’s safe­ty. To be sure, the drug has safe­ty is­sues. There were 4 pa­tients in the study who died af­ter treat­ment. Sev­er­al oth­ers died for un­re­lat­ed is­sues. But…with on­ly a 2% rate of cy­tokine re­lease syn­drome, Bris­tol-My­ers has a shot at a dif­fer­en­ti­at­ed safe­ty pro­file.

“There is a po­ten­tial these pa­tients can be treat­ed on an out­pa­tient ba­sis,” says Samit Hi­rawat, the chief med­ical of­fi­cer at Bris­tol-My­ers. He not­ed that 26% of pa­tients were nev­er ad­mit­ted, while 76% were ad­mit­ted 4 days or lat­er af­ter ther­a­py. The key is to treat them at a hos­pi­tal with the in­fra­struc­ture to pro­vide care 24/7, so a pa­tient can be ad­mit­ted at any time lat­er if need­ed.

How that will fly with pay­ers af­ter ri­vals have been on the mar­ket for about 3 years, with new ev­i­dence that ear­li­er use of steroids can dra­mat­i­cal­ly re­duce CRS and con­sid­er­able dura­bil­i­ty of re­sponse, will have to be seen.

But time is not on Bris­tol-My­ers’ side. Liso-cel is the long de­layed fol­lowup to the dis­as­trous JCAR015, which killed a num­ber of pa­tients. Their set­back threw them years off sched­ule. And ri­vals are ad­vanc­ing off-the-shelf al­ter­na­tives or oth­er new ap­proach­es that could knock the pi­o­neers com­plete­ly out of the game. In the mean­time, Bris­tol-My­ers is gath­er­ing its own dura­bil­i­ty da­ta and will grad­u­al­ly see if their mix of CD4 and CD8 cells can do bet­ter.

The main in­ter­est now is in the time­line around the ap­proval. Hi­rawat says they’ll ask for pri­or­i­ty re­view, and there’s every rea­son to be­lieve that reg­u­la­tors will move swift­ly — bar­ring a nasty sur­prise.

ZS Per­spec­tive: 3 Pre­dic­tions on the Fu­ture of Cell & Gene Ther­a­pies

The field of cell and gene therapies (C&GTs) has seen a renaissance, with first generation commercial therapies such as Kymriah, Yescarta, and Luxturna laying the groundwork for an incoming wave of potentially transformative C&GTs that aim to address diverse disease areas. With this renaissance comes several potential opportunities, of which we discuss three predictions below.

Allogenic Natural Killer (NK) Cells have the potential to displace current Cell Therapies in oncology if proven durable.

Despite being early in development, Allogenic NKs are proving to be an attractive new treatment paradigm in oncology. The question of durability of response with allogenic therapies is still an unknown. Fate Therapeutics’ recent phase 1 data for FT516 showed relatively quicker relapses vs already approved autologous CAR-Ts. However, other manufacturers, like Allogene for their allogenic CAR-T therapy ALLO-501A, are exploring novel lymphodepletion approaches to improve persistence of allogenic cells. Nevertheless, allogenic NKs demonstrate a strong value proposition relative to their T cell counterparts due to comparable response rates (so far) combined with the added advantage of a significantly safer AE profile. Specifically, little to no risk of graft versus host disease (GvHD), cytotoxic release syndrome (CRS), and neurotoxicity (NT) have been seen so far with allogenic NK cells (Fig. 1). In addition, being able to harness an allogenic cell source gives way to operational advantages as “off-the-shelf” products provide improved turnaround time (TAT), scalability, and potentially reduced cost. NKs are currently in development for a variety of overlapping hematological indications with chimeric antigen receptor T cells (CAR-Ts) today, and the question remains to what extent they will disrupt the current cell therapy landscape.

Can­cer pow­er­house As­traZeneca rolls the dice on a $75M cash bet on a buzzy up­start in the on­col­o­gy field

After establishing itself in the front ranks of cancer drug developers and marketers, AstraZeneca is putting its scientific shoulder — and a significant amount of cash — behind the wheel of a brash new upstart in the biotech world.

The pharma giant trumpeted news this morning that it is handing over $75 million upfront to ally itself with Scorpion Therapeutics, one of those biotechs that was newly birthed by some top scientific, venture and executive talent and bequeathed with a fortune by way of a bankroll to advance an only hazily explained drug platform. And they are still very much in the discovery and preclinical phase.

A $3B+ peak sales win? Pfiz­er thinks so, as FDA of­fers a tardy green light to its JAK1 drug abroc­i­tinib

Back in the fall of 2020, newly crowned Pfizer chief Albert Bourla confidently put their JAK1 inhibitor abrocitinib at the top of the list of blockbuster drugs in the late-stage pipeline with a $3 billion-plus peak sales estimate.

Since then it’s been subjected to serious criticism for the safety warnings associated with the class, held back by a cautious FDA and questioned when researchers rolled out a top-line boast that their heavyweight contender had beaten the champ in the field of atopic dermatitis — Dupixent — in a head-to-head study.

Rob Califf ad­vances as Biden's FDA nom­i­nee, with a close com­mit­tee vote

Rob Califf’s second confirmation process as FDA commissioner is already much more difficult than his near unanimous confirmation under the Obama administration.

The Senate Health Committee on Thursday voted 13-8 in favor of advancing Califf’s nomination to a full Senate vote. Several Democrats voted against Califf, including Sen. Bernie Sanders and Sen. Maggie Hassan. Several other Democrats who aren’t on the committee, like West Virginia’s Joe Manchin and Ed Markey of Massachusetts, also said Thursday that they would not vote for Califf. Markey, Hassan and Manchin all previously expressed reservations about the prospect of Janet Woodcock as an FDA commissioner nominee too.

Bio­gen vows to fight CM­S' draft cov­er­age de­ci­sion for Aduhelm be­fore April fi­nal­iza­tion

Biogen executives made clear in an investor call Thursday they are not preparing to run a new CMS-approved clinical trial for their controversial Alzheimer’s drug anytime soon.

As requested in a draft national coverage decision from CMS earlier this week, Biogen and other anti-amyloid drugs will need to show “a meaningful improvement in health outcomes” for Alzheimer’s patients in a randomized, placebo-controlled trial to get paid for their drugs, rather than just the reduction in amyloid plaques that won Aduhelm its accelerated approval in June.

CRO own­er pleads guilty to ob­struct­ing FDA in­ves­ti­ga­tion in­to fal­si­fied clin­i­cal tri­al da­ta

The co-owner of a Florida-based clinical research site pleaded guilty to lying to an FDA investigator during a 2017 inspection, revealing that she falsely portrayed part of a GlaxoSmithKline pediatric asthma study as legitimate, when in fact she knew that certain data had been falsified, the Department of Justice said Wednesday.

Three other employees — Yvelice Villaman Bencosme, Lisett Raventos and Maytee Lledo — previously pleaded guilty and were sentenced in connection with falsifying data associated with the trial at the CRO Unlimited Medical Research.

‘Skin­ny la­bels’ on gener­ics can save pa­tients mon­ey, re­search shows, but re­cent court de­ci­sions cloud fu­ture

New research shows how generic drug companies can successfully market a limited number of approved indications for a brand name drug, prior to coming to market for all of the indications. But several recent court decisions have created a layer of uncertainty around these so-called “skinny” labels.

While courts have generally allowed generic manufacturers to use their statutorily permitted skinny-label approvals, last summer, a federal circuit court found that Teva Pharmaceuticals was liable for inducing prescribers and patients to infringe GlaxoSmithKline’s patents through advertising and marketing practices that suggested Teva’s generic, with its skinny label, could be employed for the patented uses.

How a tiny Swiss lab and two old blood sam­ples cre­at­ed one of the on­ly ef­fec­tive drugs against Omi­cron (and why we have so lit­tle of it)

Exactly a decade before a novel coronavirus broke out in Wuhan, Davide Corti — a newly-minted immunologist with frameless glasses and a quick laugh — walked into a cramped lab on the top floor of an office building two hours outside Zurich. He had only enough money for two technicians and the ceiling was so low in parts that short stature was a job requirement, but Corti believed it’d be enough to test an idea he thought could change medicine.
