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.

As FDA buck­les un­der the strain of a pan­dem­ic work­load, Trump again ac­cus­es the agency of a po­lit­i­cal hit job

Peter Marks appeared before a virtual SVB Leerink audience yesterday and said that his staff at FDA’s CBER is on the verge of working around the clock. Manufacturing inspections, policy work and sponsor communications have all been pushed down the to-do list so that they can be responsive to Covid-related interactions. And the agency’s objective right now? “To save as many lives as we can,” Marks said, likening the mortality on the current outbreak as equivalent to “a nuclear bomb on a small city.”

Play-by-play of Gilead­'s $21B Im­munomedics buy­out de­tails a fren­zied push — and mints a new biotech bil­lion­aire

Immunomedics had not really been looking for a buyout when the year began. Excited by its BLA for Trodelvy, submitted to the FDA in late 2019, executive chairman Behzad Aghazadeh started off looking for potential licensing deals and zeroed in on four potential partners, including Gilead, following January’s JP Morgan Healthcare Conference in San Francisco. Such talks advanced throughout the year, with discussions advancing to the second round in mid-August.

Op-ed: Will phar­ma re­al­ly pay for Trump’s lat­est law­less promise to 33 mil­lion Medicare ben­e­fi­cia­ries? Not like­ly

Sitting atop the executive branch, President Donald Trump is the ultimate authority at the FDA. He can fast track any vaccine to approval himself. If it came to that, of course.

What he can’t do is unilaterally order the legislative branch to loosen the Treasury’s coffers for $6.6 billion. Nor can he command pharmaceutical companies to pay for $200 vouchers sent to 33 million Medicare beneficiaries for prescription drugs before the election.

FDA is­sues fi­nal rule al­low­ing im­por­ta­tion of drugs from Cana­da — but al­so keeps the pow­er to re­voke it

Just over a month away from the presidential election, the FDA has issued a final regulation fulfilling President Trump’s promise to let states import certain prescription drugs from Canada.

On Thursday, Trump told a crowd in North Carolina that the new rule goes into effect “today.” But the published regulation states that it won’t take effect for 60 days. And even then, it could be a while before cheaper drugs make it across the border.

The win­dow is wide open as four more biotechs join the go-go IPO class of 2020

It’s another day of hauling cash in the biopharma world as four more IPOs priced Friday and a fifth filed its initial paperwork.

The biggest offering comes from PMV Pharma, an oncology biotech focusing on p53 mutations, which raised $211.8 million after pricing shares at $18 apiece. Prelude Therapeutics, developing PRMT5 inhibitors for rare cancers, was next with a $158 million raise, pricing shares at $19 each. Graybug Vision raised $90 million after pricing at $16 per share for its wet AMD candidates, and breast cancer biotech Greenwich Lifesciences brought up the rear with a small, $7 million raise after pricing shares at $5.75.

J&J of­fers PhI/IIa da­ta show­ing its sin­gle-dose vac­cine can stir up suf­fi­cient im­mune re­sponse

Days after J&J dosed the first participants of its Phase III ENSEMBLE trial, the pharma giant has detailed the early-stage data that gave them confidence in a single-dose regimen.

Testing two dose levels either as a single dose or in a two-dose schedule spaced by 56 days in, the scientists from Janssen, the J&J subsidiary developing its vaccine, reported that the low dose induced a similar immune response as the high dose. The interim Phase I/IIa results were posted in a preprint on medRxiv.

An­drew Cuo­mo says New York will un­der­take its own vac­cine re­view process, and wouldn’t rec­om­mend trust­ing the fed­er­al gov­ern­ment

The concerns keep mounting over President Donald Trump’s politicization of the FDA and other federal agencies guiding the development of a safe and effective vaccine. And today, the telegenic New York governor Andrew Cuomo appeared to introduce even more politics into the matter — latest in an ongoing series of incidents that have cast the proudly independent FDA in starkly political terms.

During his daily press conference Cuomo said that the state will review any coronavirus vaccines approved by the federal government, citing a lack of trust in the Trump administration. The announcement comes one day after Trump accused the FDA of making an “extremely political” move in proposing stricter vaccine guidance.
