The lat­est up­date on NK­TR-214/Op­di­vo from Nek­tar and Bris­tol-My­ers will keep the con­tro­ver­sy burn­ing over the ORR rate

Nek­tar Ther­a­peu­tics $NK­TR man­aged to slide 1 out of its 38 evalu­able stage 4 melanoma pa­tients in­to the win col­umn with its close­ly-watched 3-month up­date on Op­di­vo/NK­TR-214’s ob­jec­tive re­sponse rate. That man­aged to nudge up the ORR from 50% — a fig­ure that rout­ed Nek­tar’s stock at AS­CO — to 53%, which isn’t like­ly to con­vince any of the crit­ics that the biotech and its part­ners at Bris­tol-My­ers Squibb have come up with the kind of com­bo that can change the stan­dard of care in the field.

But if you ex­pect any­one di­rect­ly in­volved in this study to step back from the en­thu­si­as­tic pro­jec­tions that were made on the first op­ti­mistic da­ta points, you’d be flat wrong.

Adi Diab

While the cru­cial ORR bare­ly budged, Adi Diab from MD An­der­son point­ed straight to a high­er com­plete re­sponse rate, at 24% — “which is not seen with an­oth­er com­bi­na­tion.” He’s al­so of­fer­ing a thumbs up to a 76% dis­ease con­trol rate — up from 71% at AS­CO — as ev­i­dence that they’re on to some­thing spe­cial.

Sev­er­al an­a­lysts — in­clud­ing some in the Ever­cor­eISI team — had been look­ing for some­thing in the 60%-plus range for the ORR to win back the en­thu­si­asm that has drained away for NK­TR-214, a drug that a needy Bris­tol-My­ers Squibb paid $1.85 bil­lion up­front to part­ner on ear­li­er in the year. The drug is de­signed to bind to the CD122 re­cep­tor on the sur­face of CD-8 and CD-4 pos­i­tive im­mune cells to whip up an at­tack on var­i­ous can­cers.

And Diab says they can see ex­act­ly that re­sponse in pa­tients with pos­i­tive bio­mark­er re­sults for the tu­mor mi­croen­vi­ron­ment.

As it stands, the re­searchers have a drug that ap­pears to have clear­ly waned in the more ma­ture 7.2-month me­di­an fol­lowup time for PIV­OT-02, drop­ping from 64% at the first cut of the da­ta at SITC last year. And just days ago Bris­tol-My­ers out­lined im­pres­sive 4-year over­all sur­vival re­sults from Check­Mate-067: 53% for Op­di­vo plus Yer­voy com­bo, 46% for Op­di­vo alone, and 30% for Yer­voy alone.

Diab, though, be­lieves that with bet­ter ex­pe­ri­ence us­ing the drug, and bet­ter ed­u­ca­tion for physi­cians and pa­tients, the re­sponse rate can climb back up to 60%-plus. As for Yer­voy, he adds, the CT­LA-4 has a well known tox pro­file that leads to a high rate of ad­verse events that of­ten pre­vent pa­tients from com­plet­ing treat­ment.

“We should not do com­par­isons with oth­er tri­als, it’s not kosher,” Diab tells me at one point in our con­ver­sa­tion. “But of course we’re go­ing to do it.”

There’s been some in­tense con­tro­ver­sy over their chances with this IL-2 drug, which us­es pe­gy­la­tion tech to elim­i­nate the draw­backs of the orig­i­nal ther­a­py – Pro­leukin — that made it too tox­ic to use at full mea­sure, in turn lim­it­ing its ef­fi­ca­cy.

One like­ly take­down of the Nek­tar de­fense should come soon from Aaron Wed­lund, the ex-Ker­ris­dale an­a­lyst who wrote a lengthy di­a­tribe on NK­TR-214, which he con­sid­ers will make IL-2 the next IDO, an­oth­er drug class once wide­ly hailed as the next big thing in can­cer drug com­bos now bad­ly tar­nished fol­low­ing a cat­a­stroph­ic Phase III com­bo fail­ure with Keytru­da.

Bris­tol-My­ers en­thu­si­as­ti­cal­ly bought in­to the next-gen IL-2 drug ap­proach as it’s been un­suc­cess­ful­ly de­fend­ing its PD-1/L1 crown against a hard-charg­ing Mer­ck, which has pushed Keytru­da and chemo com­bos in­to the fore­front of the lung can­cer mar­ket. IL-2, they said, would be the next log­i­cal step to PD-1 and CT­LA-4, with Yer­voy.

Any­thing that puts this drug back in the Pro­leukin cat­e­go­ry, with more IL-2 suc­ces­sors in the pipeline, won’t be wel­come by the de­vel­op­ers.

It’s im­por­tant to keep in mind that a bunch of short in­vestors had fun — and made mon­ey — pulling Nek­tar’s stock down from some stun­ning highs that it had en­joyed. Rais­ing doubts is good for spurring cor­rec­tions, and Nek­tar’s stock has tum­bled bad­ly. The ju­ry will re­main out, though, un­til the Phase III pro­gres­sion-free sur­vival da­ta comes due around the spring of 2020.

Un­til then, and maybe even af­ter, this de­bate will con­tin­ue to rage.

Nick Galakatos, Blackstone global head of life sciences

Nick Galakatos and the Black­stone team now have a record $4.6B to in­vest in bio­phar­ma, with a big fo­cus on push­ing com­pa­nies over the top

Nick Galakatos and his team at Blackstone Life Sciences have seen their biggest opportunities swell up in mostly established players who don’t have all the money they need to accomplish everything on the to-do list. And right now, with the industry booming, that’s a long list with some hefty needs.

The Blackstone team has neatly tied up the largest private fund ever raised in life sciences for making big dreams come true in biopharma. Late Thursday, Blackstone put out word that they had closed their highly anticipated fund with the projected $4.6 billion all in.

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.

Gilead boasts of pos­i­tive remde­sivir da­ta on mor­tal­i­ty — but their analy­sis pro­vokes the skep­tics

Gilead is surging again off data that suggest its antiviral remdesivir might improve survival.

The new data come from an analysis Gilead conducted comparing the death rate and recovery time of patients in one of its remdesivir trials to a group of 800 patients “with similar baseline characteristics and disease severity” who received only standard-of-care around the same time. The result, they said, suggested that patients who received remdesivir had a 62% better chance at surviving than those who did not.

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.

Hal Barron, GSK

Win or lose on the mar­ket­ing OK, the FDA just gunned down GSK’s bright hopes for their BC­MA ther­a­py

The FDA’s ODAC — the Oncologic Drugs Advisory Committee — has a well-known bias in favor of adding new cancer drugs to the market, even if efficacy is at best marginal and serious safety issues demand careful management.

Doctors want as many arrows in their quiver as they can get. And when patients are dying after failing multiple drugs, why not give it a go one more time?

GlaxoSmithKline, though, is about to test out how their new BCMA antibody drug conjugate belantamab mafodotin can do after being mauled in an in-house FDA review, ahead of the Tuesday expert panel discussion. Even if the agency goes ahead with an expected green light, this drug will likely be constrained to a small niche — icing any plans they may have for making waves in oncology anytime soon.

Covid-19 roundup: BioN­Tech go­ing head-to-head with Mod­er­na as PhI­II mR­NA launch looms; Tri­al on Shin­zo Abe’s once-fa­vorite an­tivi­ral is in­con­clu­sive

It’s a race to the Phase III finish line now for the 2 leading mRNA vaccines in the pipeline for Covid-19.

BioNTech chief Ugur Sahin told the Wall Street Journal that his company will start Phase III testing of their vaccine later this month, setting them up to lateral the data to regulators before the end of this year.

That puts them essentially on the exact same schedule as Moderna is dedicated to. The Massachusetts rival to BioNTech also expects to launch Phase III this month. Lots of rumors have circulated about delays and conflict among the scientists advancing the Moderna jab, but the biotech has consistently stuck to its plan to start a late-stage pivotal this month.

Af­ter psilo­cy­bin and ke­t­a­mine, a new biotech comes along de­vel­op­ing a drug Scott Got­tlieb fought

Andrew Kruegel was six years into his chemistry work at Columbia University, when, one day in August 2016, he learned he might have only 30 days before the government made him destroy his research.

Kruegel had been studying kratom, a leaf long used in Southeast Asia as a stimulant or for pain. It had opioid-like properties, he found, but seemed to offer pain relief without the addictive potential or respiratory side effects of traditional opioids — a riddle that might help illuminate how human opioid receptors work.

The home run count: The $100M+ mega-round boom in biotech in­spired a $7.3B feed­ing fren­zy — so far this year

Over the last 6 months there’s been a blizzard of money piling up drifts of the green stuff through the biotech landscape. And the forecast calls for more cash windfalls ahead.

Even as a global pandemic has killed more than half a million people, blighted economies and divided nations over the proper response, it’s also helped ignite an unprecedented burst of big-time investing. And not just in Covid-19 deals, as we’ve looked at before.

An­oth­er biotech IPO set-up? Multi­na­tion­al biotech leaps from round to round, scoop­ing up cash at a blis­ter­ing pace

A short four months after announcing a $75 million haul in Series B+ fundraising, the multinational biotech Harbour BioMed pulled in another round of investments and eclipsed the nine-digit mark in the process.

Harbour completed its Series C financing, the company announced Thursday morning, raising $102.8 million and bringing its total investment sum to over $300 million since its founding in late 2016. The biotech plans to use the money to transition early-stage candidates from the discovery phase, fund candidates already in the clinic, and prep late-stage candidates for commercialization.
