#ASH17: The BC­MA-tar­get­ed CAR-T bb2121 from blue­bird and Cel­gene takes a star turn in the spot­light

A few days ago, Cel­gene $CELG launched the piv­otal Phase II/III study that will dic­tate the fu­ture of the BC­MA-tar­get­ing bb2121, the CAR-T in-li­censed from blue­bird bio $BLUE. And if they come close to the da­ta that blue­bird has on of­fer at ASH this week­end, this drug will go on to blaze a big trail in the mar­ket as the de­vel­op­ers move on to the next big fo­cus in the field of en­gi­neered T cells.

In­ves­ti­ga­tors in the Phase Ib study out­lined a 94% over­all re­sponse rate for bb2121, with a jaw-drop­ping 56% com­plete re­sponse rate among a small group of 18 pa­tients in heav­i­ly pre­treat­ed ac­tive dose co­horts. Three of those 10 CRs, though, were un­con­firmed at the time of the pre­sen­ta­tion in At­lanta.

The me­di­an pro­gres­sion-free re­sponse rate had yet to be reached. But the 6- and 9-month PFS marks were passed with 81% and 71% rates.

“This is what we all dream about,” says blue­bird CEO Nick Leschly, “this kind of da­ta for pa­tients that are in a re­al­ly, re­al­ly tough po­si­tion.”

Blue­bird’s stock jumped 24% in pre-mar­ket trad­ing Mon­day, with Cel­gene {$CELG) up close to 5%.

To be sure there was plen­ty of tox­i­c­i­ty on the dose rang­ing study, with an ad­vanced pa­tient with a pun­ish­ing tu­mor bur­den ex­pe­ri­enc­ing grade 4 neu­ro­tox­i­c­i­ty with cere­bral ede­ma and sub­arach­noid he­m­or­rhage af­ter get­ting the high dose: 450 x 106 CAR+ T cells. And there were a num­ber of cas­es of cy­tokine re­lease syn­drome, a hall­mark of these first gen­er­a­tion CAR-Ts go­ing through the clin­ic.

Cel­gene will now take 150 to 300 mil­lion cell dos­es in­to the land­mark study with about 80 pa­tients, look­ing to see large­ly if it can repli­cate any­thing sim­i­lar. If they are suc­cess­ful, the part­ners can look for­ward to a block­buster mar­ket for one of the most wide­ly an­tic­i­pat­ed late-stage stud­ies in on­col­o­gy.

The da­ta un­der­score the po­ten­tial of BC­MA as a tar­get in the field, which is see­ing the first pi­o­neers hit the mar­ket by hit­ting CD19 with ma­jor ef­fect. The da­ta will cer­tain­ly bright­en the stage for blue­bird and Cel­gene, the clear lead­ers in the field, as a bevy of ri­vals fol­low up in hopes of catch­ing or leapfrog­ging the fron­trun­ners.

Juno, mak­ing a CAR-T come­back with JCAR017, just bagged a gam­ma sec­re­tase in­hibitor from Eli Lil­ly for its BM­CA ther­a­py, adding IP agree­ments with the Fred Hutch and On­co­Track­er on their com­bo ap­proach.

But blue­bird isn’t sit­ting still. It’s al­so snap­ping up new tech to keep its cut­ting edge, like the CAR-en­gi­neered gam­ma delta T cell pact it struck with Scot­land’s TC Bio­Pharm a few days ago.

“We’ve got all cylin­ders fir­ing,” says David David­son, the blue­bird chief med­ical of­fi­cer.

Ex­clu­sive: GSK’s Hal Bar­ron al­lies with Rick Klaus­ner’s $600M cell ther­a­py start­up, look­ing to break new ground blitz­ing sol­id tu­mors

LONDON — Chances are, you’ve heard little or nothing about Rick Klausner’s startup Lyell. But that ends now.

Klausner, the former head of the National Cancer Institute, former executive director for global health at the Gates Foundation, co-founder at Juno and one of the leaders in the booming cell therapy field, has brought together one of the most prominent teams of scientists tackling cell therapy 2.0 — highlighted by a quest to bridge a daunting tech gap that separates some profound advances in blood cancers with solid tumors. And today he’s officially adding Hal Barron and GlaxoSmithKline as a major league collaborator which is pitching in a large portion of the $600 million he’s raised in the past year to make that vision a reality.

“We’ve being staying stealth,” Klausner tells me, then adding with a chuckle: “and going back to stealth after this.”

“Cell therapy has a lot of challenges,” notes Barron, the R&D chief at GSK, ticking off the resistance put up by solid tumors to cell therapies, the vein-to-vein time involved in taking immune cells out of patients, engineering them to attack cancer cells, and getting them back in, and more. “Over the years Rick and I talked about how it would be wonderful to take that on as a mission.”

First place fin­ish: Eli Lil­ly just moved to fran­chise leader with their sec­ond mi­graine drug OK in 1 year

In a rare twist for Eli Lilly’s historically slow-moving R&D group, the pharma giant has seized bragging rights to a first-in-class new drug approval. And all signs point to an aggressive marketing followup as they look to outclass some major franchise rivals hobbled by internal dissension.

The FDA came through with an OK for lasmiditan on Friday evening, branding it as Reyvow and lining it up — once a substance classification comes through from the DEA — for a major market release. The oral drug binds to 5-HT1F receptors and is designed to stop an acute migraine after it starts. That makes it a complementary therapy to their CGRP drug Emgality, which has a statistically significant impact on preventing attacks.

Allogene HQ Open House on September 17, 2019 in South San Francisco. (Jeff Rumans, Endpoints News)

The next 10 years: Where is biotech head­ed?

The last 10 years have seen a revolution in drug development. Timelines have shortened, particularly in oncology. Regulators have opened up. Investment has skyrocketed. China became a player. Biotechs have multiplied as gene and cell therapy has exploded — offering major new advances in the way diseases are treated, and sometimes cured.

So where are we headed from here? I journeyed out to San Francisco in September to discuss the answer to that question at Allogene’s open house. If the last 10 years have been an eye-opener, what does the next decade hold in store?

Court green-lights Clo­vis case af­ter de­tail­ing ev­i­dence the board ‘ig­nored red flags’ on false safe­ty and ef­fi­ca­cy da­ta

Clovis investors have cleared a major hurdle in their long-running case against the board of directors, with a Delaware court making a rare finding that they had a strong enough case against the board to proceed with the action.

In a detailed ruling at the beginning of the month that’s been getting careful scrutiny at firms specializing in biotech and corporate governance, the Delaware Court of Chancery found that the attorneys for the investors had made a careful case that the board — a collection of experts that includes high-profile biotech entrepreneurs, a Harvard professor and well-known investigator as well as Clovis CEO Patrick Mahaffy — repeatedly ignored obvious warnings that Mahaffy’s executive crew was touting inflated, unconfirmed data for their big drug Roci. Serious safety issues were also reportedly overlooked while the company continued a fundraising campaign that brought in more than a half-billion dollars. And that leaves the board open to claims related to their role in the fiasco.

The bottom line:

Bill Gates backs Gink­go Biowork­s' $350M raise to fu­el the buzzy syn­thet­ic bi­ol­o­gy 'rev­o­lu­tion'

If you want to understand Ginkgo Bioworks, the name should suffice: Bioworks, a spin off “ironworks,” that old industrial linchpin devoted to leveraging scale as a wellspring for vast new industries capable of remaking society. Ginkgo wants to be the ironworks for the revolution it’s heralded with as much fanfare as they can, playing off of one of the buzziest technologies in biotech.

UCB bags a ri­val to Soliris in $2.1B buy­out deal — but will an in­creas­ing­ly vig­i­lant FTC sign off?

UCB is buying out Ra Pharma $RARX, announcing an acquisition deal that rings up at $48 a share, or $2.1 billion net of cash, and puts them toe-to-toe with Alexion on a clinical showdown.

Ra shares closed at $22.70 on Wednesday.

There’s a small pipeline in play at Ra, but UCB is going for the lead drug — a C5 inhibitor called zilucoplan in Phase III for myasthenia gravis (MG) looking to play rival to Alexion’s Soliris. Soliris has the market advantage, though, with a much earlier approval in MG in late 2017 that UCB feels confident in challenging.

Two years after treatment, the best thing that GenSight Biologics $SIGHT can say about their gene therapy for vision-destroying cases of Leber Hereditary Optic Neuropathy is that it’s just a bit better than a placebo — just maybe because one treatment can cover both eyes.

ARCH, Soft­Bank-backed Vir Biotech­nol­o­gy un­der­whelms with $143 mil­lion IPO

George Scangos went back to Wall Street, and came back 700 million pennies short.

Scangos’ vaunted startup Vir Biotechnology raised $143 million in an IPO they hoped would earn $150 million. Shares were priced at $20, the low-end of the $20-$22 target.

Launched with backing from ARCH Venture’s Robert Nelsen, Masayoshi Son’s SoftBank Vision Fund, and the Bill & Melinda Gates Foundation, the infectious disease startup was one of a new wave of well-resourced biotechs that emerged with deep enough coffers to pursue a full R&D line rather than slowly build their case by picking off a single lead program.
