Af­ter be­ing spurned at the FDA, PTC buys a con­tro­ver­sial Duchenne MD ther­a­py from Marathon

Af­ter be­ing stung by a fierce back­lash over its plans to sell a cheap, old steroid for Duchenne mus­cu­lar dy­s­tro­phy for $89,000 a year, Marathon Phar­ma­ceu­ti­cals is get­ting out. The com­pa­ny an­nounced this morn­ing that it is sell­ing de­flaza­cort (Em­flaza) to Duchenne MD play­er PTC Ther­a­peu­tics $PTCT, which has been strug­gling to get the FDA to pro­vide a se­ri­ous re­view for its own failed drug.

Marathon is get­ting $140 mil­lion in cash and stock in the deal, along with a shot at a one-time $50 mil­lion sales bonus on the ta­ble and a roy­al­ty stream that will ac­count for a low-to-mid 20s per­cent­age of the rev­enue.

PTC Ther­a­peu­tics CEO Stu­art Peltz

PTC CEO Stu­art Peltz doesn’t say in the re­lease how much he plans to charge for de­flaza­cort. The com­pa­ny’s stock slid 13% af­ter the news hit.

Marathon trig­gered a storm of crit­i­cism with its plans, which is con­tin­u­ing un­abat­ed now with a new fo­cus on the FDA’s role in the ap­proval. A large num­ber of Duchenne par­ents were able to buy gener­ic de­flaza­cort over­seas for around $1,000 a year, and crit­ics saw Marathon’s move as an­oth­er in a se­ries of price goug­ing scan­dals.

That scan­dal is now PTC’s to deal with.

“With our near­ly 20-year com­mit­ment to the Duchenne com­mu­ni­ty, it is deeply mean­ing­ful for us to bring this crit­i­cal ther­a­py to U.S. pa­tients,” said Peltz in a state­ment. “We be­lieve Em­flaza is a dis­ease-mod­i­fy­ing ther­a­py that has been shown to slow dis­ease pro­gres­sion. In keep­ing with PTC’s mis­sion, we are ex­cit­ed to work with the com­mu­ni­ty to raise the stan­dard of care for DMD pa­tients.”

Claim­ing that de­flaza­cort is a dis­ease mod­i­fy­ing ther­a­py will sur­prise many in the Duchenne com­mu­ni­ty. Like any steroid, it strength­ens pa­tients at a cost. Many of the par­ents came to pre­fer de­flazafort over pred­nisone be­cause it is as­so­ci­at­ed with less weight gain.

In ac­quir­ing the old steroid to be sold as a brand­ed ther­a­py, PTC is al­so adopt­ing Marathon’s claim that the ap­proval makes it pos­si­ble to ex­pand ac­cess — now “lim­it­ed to a small num­ber of pa­tients,” Peltz said in a call with an­a­lysts to­day — to all pa­tients over the age of 5.

Mark Rather, PTC CCO

“We plan to re­ex­am­ine the price of Em­flaza,” added Mark Rothera, PTC’s chief com­mer­cial of­fi­cer. “This is a clas­sic or­phan drug launch that we’re fac­ing in the Unit­ed States.”

“It re­al­ly wasn’t avail­able to pa­tients,” Peltz told an­a­lysts, es­ti­mat­ing that few­er than 10% of the pa­tients had ac­cess to the steroid.

Ac­cord­ing to Duchenne ad­vo­cate Chris­tine Mc­Sh­er­ry, though, quite a few fam­i­lies had no prob­lem get­ting over­seas sup­plies of the steroid. Mc­Sh­er­ry ini­tial­ly es­ti­mat­ed that 40% to 50% of the DMD kids are al­ready on de­flaza­cort and will now be forced to switch to the high­er priced US sup­pli­er, then ad­just­ed that down to a con­ser­v­a­tive 25%.

Law­mak­ers, in­clud­ing Sen­a­tor Bernie Sanders, have blast­ed Marathon’s claims that it need­ed to charge a high price to even­tu­al­ly re­gain the cost of de­vel­op­ment.

Peltz has tried and failed to prove that PTC’s drug ataluren — which failed back-to-back stud­ies and re­cent­ly flopped for cys­tic fi­bro­sis — could ben­e­fit Duchenne par­ents. He con­tin­ues to in­sist that the “to­tal­i­ty” of the da­ta proves its worth, but the FDA re­fused to even file their ap­pli­ca­tion, say­ing they didn’t have the da­ta need­ed for a re­view. PTC, though, re­cent­ly lever­aged the reg­u­la­tions to force a PDU­FA date for their drug. And ex­ecs styled this new deal as an open­ing to start US com­mer­cial­iza­tion ef­forts as it pre­pares to push ataluren in­to the mar­ket.

Eu­ro­pean reg­u­la­tors, mean­while, did give the drug a con­di­tion­al ap­proval, ex­tend­ing that with a new re­quire­ment to com­plete an ad­di­tion­al study in the next five years.

Op­ti­miz­ing Cell and Gene Ther­a­py De­vel­op­ment and Pro­duc­tion: How Tech­nol­o­gy Providers Like Corn­ing Life Sci­ences are Spurring In­no­va­tion

Bay­er sounds re­treat from a $670 mil­lion CAR-T pact in the wake of a pa­tient death

Two months after Atara Biotherapeutics hit the hold button on its lead CAR-T 2.0 therapy following a patient death, putting the company under the watchful eye of the FDA, its Big Pharma partners at Bayer are bowing out of a $670 million global alliance. And the move is forcing a revamp of Atara’s pipeline plans, even as research execs vow to continue work on the two drugs allied with Bayer 18 months ago, which delivered a $60 million cash upfront.

Sanofi and Re­gen­eron clear the fin­ish line in an in­flam­ma­to­ry esoph­a­gus dis­ease, leav­ing Take­da in the dust

With atopic dermatitis rivals breathing down Dupixent’s neck, Sanofi and Regeneron on Friday secured a first win in new territory in what Sanofi’s head of immunology and inflammation Naimish Patel called the fastest approval he’s ever seen.

The FDA approved Dupixent on Friday to treat patients 12 years and older with eosinophilic esophagitis (EoE), an inflammatory condition that causes swelling and scarring of the esophagus. The approval came just a couple months after regulators granted Dupixent priority review, and months ahead of its PDUFA date on Aug. 3.

Fu­ji­film con­tin­ues its biotech build­ing spree with new fa­cil­i­ty in Chi­na

A Japanese conglomerate is making a big play in China with the opening of a new facility, as it continues to expand.

Fujifilm Irvine Scientific has opened its new Innovation and Collaboration Center in Suzhou New District, China, an area in Jiangsu province specifically designated for technological and industrial development.

According to Fujifilm, the 12,000-square-foot site will be responsible for the company’s cell culture media optimization, analysis and design services. Cell culture media itself often requires customization of formulas and protocols to achieve the desired quantity and quality of therapeutic desired. Fujifilm Irvine Scientific is offering these services from its headquarters in California and Japan to its customers globally, as well as in China now.

Mary­land of­fers loan to Clene de­spite ALS tri­al bumps

Even after Utah-based Clene failed to hit its primary endpoints for its ALS drug last year, the state of Maryland is putting its money at least behind Clene’s manufacturing facility.

The Maryland Board of Public Works has finalized a $3 million, 60-month loan facility with Clene Nanomedicine. The loan was provided by the state’s Neighborhood BusinessWorks program within the Maryland Department of Housing and Community Development.

SQZ's out­side-the-box man­u­fac­tur­ing method slash­es pro­duc­tion time in ear­ly in study

At ASCO 2021 in June of last year, SQZ Biotech showcased a glimpse of its unorthodox cell therapy manufacturing tech. And on Wednesday, the Watertown, MA, company announced that its first-generation system showed comparable or better performance than a conventional clean-room-based manufacturing process.

The study was non-clinical. Clinical trials are expected by the first half of 2023.

SQZ’s device opens up a temporary window by cell-squeezing to deliver cargoes into cells. Its average processing time was less than six hours per batch, which is more than half the time than conventional methods. The company is planning to use the technology in its first red blood cell derived program for celiac disease. That IND is set to be submitted in the first half of 2023, the company said.

With mon­key­pox cas­es ris­ing, one Eu­ro­pean coun­try is lock­ing down a small­pox vac­cine con­tract

As the global number of confirmed and suspected monkeypox cases continues to slowly climb, one country is trying to get a head start on potential vaccine stocking.

Bavarian Nordic signed a contract with an undisclosed European nation to supply its smallpox vaccine in response to new cases this month, the company announced Thursday morning. The continent saw its first monkeypox case confirmed about two weeks ago, with both the UK and Portugal seeing cases, according to the Washington Post.
