Can tiny Mus­tang Bio com­pete on the CAR-T front with gi­ants like No­var­tis and Gilead? Man­ny Litch­man aims to find out

Now that No­var­tis and Gilead have picked up the first two ap­provals for CAR-T drugs, you can ex­pect to see ri­vals com­ing along who will probe for any weak­ness­es in their ap­proach, look­ing to com­pete on the next wave of per­son­al­ized cell ther­a­pies head­ed through the clin­ic.

The small crew at Mus­tang Bio — $MBIO, up 11% to­day — has some big am­bi­tions on that score, and to­day they’re adding some man­u­fac­tur­ing ca­pac­i­ty that the com­pa­ny be­lieves will be cen­tral to its abil­i­ty to even­tu­al­ly com­pete with these two gi­ants.

Man­ny Litch­man

Mus­tang has inked a lease deal with the UMass Med­i­cine Sci­ence Park in Worces­ter, MA, where they ex­pect to be­gin pro­duc­tion of their CAR-Ts next year. And they’ll be aim­ing to make these cell ther­a­pies for ear­ly-stage stud­ies for glioblas­toma and acute myeloid leukemia and a grow­ing sta­ble of pre­clin­i­cal ef­forts.

Look­ing for com­pet­i­tive ad­van­tages at this stage of the game will re­ly quite a lot on a “more stream­lined, more cost ef­fec­tive man­u­fac­tur­ing ap­proach,” CEO Man­ny Litch­man tells me. “Every­thing re­al­ly has cost in mind,” he adds, siz­ing up the first two ther­a­pies that come with hefty six-fig­ure price tags.

“Look in the black box of man­u­fac­tur­ing,” he says, and you can see “dozens of pa­ra­me­ters that can vary.”

There’s more reengi­neer­ing work to be done to make CAR-Ts bet­ter at com­bat­ting can­cers like glioblas­toma and AML, he adds. In­ves­ti­ga­tors, for ex­am­ple, have been bal­anc­ing the im­pact of quick ver­sus slow­er ac­tion of the ther­a­peu­tic — slow­er ac­tion ap­pears to be more durable — along with a mul­ti­tude of com­bi­na­tion ap­proach­es that need to be ex­plored.

There’s enough po­ten­tial in these new ap­proach­es to of­fer an open­ing for a com­pa­ny like Mus­tang to step in and ex­ploit new op­por­tu­ni­ties, he be­lieves.

Litch­man left the helm at Arv­inas, a pro­tein degra­da­tion biotech spun out of the lab of Yale’s Craig Crews, to take the lunge at CAR-T. It’s a field he knows some­thing about. As for­mer head of on­col­o­gy BD at No­var­tis, Litch­man was present at the cre­ation of the Penn/No­var­tis deal that set the phar­ma gi­ant down the path to­ward an his­toric CAR-T ap­proval. He was pro­gram head of CTL019 for awhile. And he’s fol­low­ing in much the same path that the pi­o­neers — along with Kite and Juno — did, let­ting the sci­en­tif­ic founders do the ear­ly-stage re­search work that will be used to set up the fast-paced piv­otal de­vel­op­ment pro­grams to come.

Stephen For­man

In Mus­tang’s case, that in­volves Stephen For­man’s lab­o­ra­to­ry at City of Hope Na­tion­al Med­ical Cen­ter and top re­searchers at the Fred Hutchin­son Can­cer Re­search Cen­ter, where Oliv­er Press and Bri­an Till have been build­ing a T cell ther­a­py which ex­press­es a CD20-spe­cif­ic chimeric anti­gen re­cep­tor. That work has ex­pand­ed Mus­tang’s pipeline to 6 clin­i­cal and pre­clin­i­cal ef­forts.

The Cal­i­for­nia In­sti­tute for Re­gen­er­a­tive Med­i­cine, rest­less­ly look­ing to make a clin­i­cal mark af­ter years in­vest­ing in labs, just days ago pro­vid­ed a $12.8 mil­lion grant to the City of Hope for the Phase I glioblas­toma study. And that comes on top of a $94.5 mil­lion raise in Feb­ru­ary from a pri­vate place­ment arranged by its par­ent com­pa­ny Fortress, which is build­ing a port­fo­lio of biotechs.

Try­ing to leapfrog in­to a clin­i­cal ri­val­ry in a com­plex are­na like this will cost much, much more than that. And Litch­man tells me he has plans to raise some­where be­tween $60 mil­lion and $100 mil­lion more next year.

Right now, Mus­tang has 5 full timers, a tiny boat­load of staffers com­pared to the jug­ger­nauts crewed by No­var­tis and Gilead’s Kite. Juno al­so has a much larg­er op­er­a­tion look­ing to make a come­back af­ter their lead ther­a­py was de­stroyed by its lethal tox­i­c­i­ty. But Litch­man plans to up that to about 20 over the next year, while the in­de­pen­dent sci­en­tists con­tin­ue to do the heavy lift­ing in the ear­ly stud­ies.

This is one race that Litch­man says is still very much just be­gin­ning. And it won’t be dom­i­nat­ed by a hand­ful of lead­ers.

UP­DAT­ED: Sanofi CEO Hud­son lays out new R&D fo­cus — chop­ping di­a­betes, car­dio and slash­ing $2B-plus costs in sur­gi­cal dis­sec­tion

Earlier on Monday, new Sanofi CEO Paul Hudson baited the hook on his upcoming strategy presentation Tuesday with a tell-tale deal to buy Synthorx for $2.5 billion. That fits squarely with hints that he’s pointing the company to a bigger future in oncology, which also squares with a major industry tilt.

In a big reveal later in the day, though, Hudson offered a slate of stunners on his plans to surgically dissect and reassemble the portfoloio, saying that the company is dropping cardio and diabetes research — which covers two of its biggest franchise arenas. Sanofi missed the boat on developing new diabetes drugs, and now it’s pulling out entirely. As part of the pullback, it’s dropping efpeglenatide, their once-weekly GLP-1 injection for diabetes.

“To be out of cardiovascular and diabetes is not easy for a company like ours with an incredibly proud history,” Hudson said on a call with reporters, according to the Wall Street Journal. “As tough a choice as that is, we’re making that choice.”

De­vel­op­ment of the Next Gen­er­a­tion NKG2D CAR T-cell Man­u­fac­tur­ing Process

Celyad’s view on developing and delivering a CAR T-cell therapy with multi-tumor specificity combined with cell manufacturing success
Overview
Transitioning potential therapeutic assets from academia into the commercial environment is an exercise that is largely underappreciated by stakeholders, except for drug developers themselves. The promise of preclinical or early clinical results drives enthusiasm, but the pragmatic delivery of a therapy outside of small, local testing is most often a major challenge for drug developers especially, including among other things, the manufacturing challenges that surround the production of just-in-time and personalized autologous cell therapy products.

What does $6.9B buy these days in on­col­o­gy R&D? As­traZeneca has a land­mark an­swer

Given the way the FDA has been whisking through new drug approvals months ahead of their PDUFA date, AstraZeneca and their partners Daiichi Sankyo may not have to wait until Q2 of next year to get a green light on trastuzumab deruxtecan (DS-8201).

The pharma giant this morning played their ace in the hole, showing off why they were willing to commit to a $6.9 billion deal — with $1.35 billion in a cash upfront — to partner on the drug.

FDA in-house re­view spot­lights an is­sue with one of Hori­zon's end­points but notes ef­fi­ca­cy for lead drug

The FDA in-house review highlights a disagreement of investigators’ use of a key endpoint by Horizon Pharma in the late-stage trial for the top drug in its pipeline, but largely agreed that the antibody was effective.

Horizon submitted a BLA for thyroid eye disease (TED) drug teprotumumab in March, less than two years after they bought the drug (and the rest of a division) from Narrow River for $145 million upfront. With breakthrough status, priority review, orphan designation and in-house sales projections of up to $750 million, the one-time Roche reject became the marquee pipeline asset for a company that’s developed some of the world’s most expensive drugs.

Seat­tle Ge­net­ics de­tails pos­i­tive OS and PFS da­ta for tu­ca­tinib in breast can­cer

Seattle Genetics $SGEN is showing off more positive data around tucatinib, its pivotal-stage drug for HER2 positive breast cancer.

A month after hearing about solidly upbeat hazard ratios, we learned today that the estimated progression-free survival rate at one year was 33% in the tucatinib arm compared to 12% for patients taking trastuzumab and capecitabine alone.

Median PFS was 7.8 months (95% CI: 7.5, 9.6) in the tucatinib arm, compared to 5.6 months (95% CI: 4.2, 7.1) in the control arm.

Bat­tered, cash hun­gry In­tec feels the burn of No­var­tis re­jec­tion

It’s a case of some bad timing for Intec.

Just when a key trial testing the company’s Accordion drug delivery tech imploded in Parkinson’s disease, they handed Novartis data from a successful PK study of a custom Accordion pill engineered to deliver a Novartis compound to entice the Swiss drugmaker into signing a licensing agreement.

Novartis said thanks, but no thanks.

For the cash-strapped Israeli drug developer, the failure to clinch the deal marks a big blow. As of the third quarter, the company has $15.7 million in cash and equivalents, which HC Wainwright analysts estimate will keep the lights on into mid-2020.

Bris­tol-My­ers shows off a low-pro­file AML con­tender it gained from Cel­gene buy­out — and they’re tak­ing it straight to the FDA

Bristol-Myers Squibb reaped an enormous pipeline with its much-criticized $64 billion megadeal to buy Celgene. And it got a few hidden gems in the deal.

One of those gems was brought out for display on Tuesday, with a late-breaker at ASH on CC-486, which is now being prepped for regulatory filings at the FDA and elsewhere.

Celgene top-lined the positive results in a maintenance setting for acute myeloid leukemia a few months ago, but at ASH investigators pulled back the curtains on the all-important data they believe will give them an advantage in the commercial wars to come.

De­sert­ed by Astel­las and Mer­ck, lit­tle Cor­re­vio still can't win over FDA pan­el con­cerned with its AFib drug's safe­ty

When the FDA spurned Astellas’ pitch for atrial fibrillation drug vernakalant in 2008, regulators made it abundantly clear that it wasn’t the efficacy they had a problem with — two Phase III trials had shown the drug successfully restored 52% of patients’ heartbeat from irregular to normal — but the cardio safety issues for a drug that was to compete with well established, low-risk options. One licensing deal, one clinical hold and several studies later, the chances of approval aren’t looking any better.

New trade deal knocks out long-sought patent pro­tec­tions for drug­mak­ers

House Democrats negotiating with the Trump Administration on a new North American trade deal settled early on four issues: enforcement, labor and environmental standards and drug pricing.

On drug pricing, Politico reports, Trump crumbled within weeks of heightened negotiations.
