From part­ner to knight in shin­ing ar­mor: Cas­tle Creek to buy Fi­bro­cell

In April, Cas­tle Creek swooped in to part­ner with the em­bat­tled gene and cell ther­a­py Fi­bro­cell to shep­herd its lead gene ther­a­py for a type of “but­ter­fly” dis­ease in­to late-stage de­vel­op­ment. Now, the New Jer­sey-based der­ma­tol­ogy com­pa­ny is ac­quir­ing its part­ner in a deal worth $63.3 mil­lion.

Cas­tle Creek CEO Greg Wu­jek

Penn­syl­va­nia-based Fi­bro­cell last year ini­ti­at­ed a re­view of strate­gic al­ter­na­tives, in­clud­ing a sale.

Its lead drug FCX-007 is en­gi­neered to treat the un­der­ly­ing cause of re­ces­sive dy­s­troph­ic epi­der­mol­y­sis bul­losa, which is caused by the de­fi­cien­cy of the pro­tein COL7. Cells are ex­tract­ed from the pa­tient, ge­net­i­cal­ly mod­i­fied, and then used to treat wounds by lo­cal in­jec­tion, avoid­ing sys­temic dis­tri­b­u­tion.

A late-stage study for FCX-007 was kicked off in Ju­ly, and if all goes well, a mar­ket­ing ap­pli­ca­tion for the treat­ment is ex­pect­ed to be sub­mit­ted in 2021, Fi­bro­cell said on Thurs­day. The com­pa­ny, which al­so counts In­trex­on $XON as a part­ner, has an ex­per­i­men­tal gene ther­a­py FCX-013 in ear­ly-stage de­vel­op­ment for mod­er­ate to se­vere lo­cal­ized scle­ro­der­ma.

Epi­der­mol­y­sis Bul­losa (EB) is a group of ge­net­ic skin con­di­tions that cause the skin to blis­ter and tear due to min­i­mal con­tact — in­fants born with the dis­ease are called ‘but­ter­fly chil­dren’ as their skin is con­sid­ered as frag­ile as a wing of a but­ter­fly.

Cas­tle Creek Phar­ma­ceu­ti­cals — one of for­mer Marathon chief Jeff Aronin’s port­fo­lio com­pa­nies un­der his flag­ship in­vest­ment en­gine Paragon Bio­sciences — has its own EB drug in de­vel­op­ment: CCP-020 is a late-stage top­i­cal oint­ment un­der de­vel­op­ment for use in epi­der­mol­y­sis bul­losa sim­plex. The drug is a re­pur­posed an oral or­phan treat­ment called di­ac­ere­in, which is ap­proved to treat joint swelling or pain in the EU, but its use is re­strict­ed due to the risks of di­ar­rhea and liv­er prob­lems.

“Fol­low­ing our li­cens­ing agree­ment to de­vel­op and com­mer­cial­ize FCX-007, our ex­pe­ri­ence work­ing to­geth­er on rare der­ma­to­log­i­cal con­di­tions caused us to quick­ly re­al­ize that Cas­tle Creek and Fi­bro­cell could achieve even greater syn­er­gies by com­bin­ing the com­pa­nies in­to one,” said Greg Wu­jek, CEO of Cas­tle Creek Phar­ma­ceu­ti­cals, in a state­ment.

Cas­tle Creek has agreed to pay $3 per Fi­bro­cell share $FC­SC, which is a near­ly 64% pre­mi­um to the com­pa­ny’s Thurs­day clos­ing. The deal, in which Cas­tle Creek will ab­sorb Fi­bro­cell’s debt, is ex­pect­ed to close by the fourth quar­ter.

UP­DAT­ED: Mer­ck pulls Keytru­da in SCLC af­ter ac­cel­er­at­ed nod. Is the FDA get­ting tough on drug­mak­ers that don't hit their marks?

In what could be an early shot in the battle against drugmakers that whiff on confirmatory studies to support accelerated approvals, the FDA ordered Bristol Myers Squibb late last year to give up Opdivo’s approval in SCLC. Now, Merck is next on the firing line — are we seeing the FDA buckling down on post-marketing offenders?

Merck has withdrawn its marketing approval for PD-(L)1 inhibitor Keytruda in metastatic small cell lung cancer as part of what it describes as an “industry-wide evaluation” by the FDA of drugs that do not meet the post-marketing checkpoints on which their accelerated nods were based, the company said Monday.

Ab­b­Vie tees up a biotech buy­out af­ter siz­ing up their Parkin­son's drug spun out of Ke­van Shokat's lab

AbbVie has teed up a small but intriguing biotech buyout after looking over the preclinical work it’s been doing in Parkinson’s disease.

The company is called Mitokinin, a Bay Area biotech spun out of the lab of UCSF’s Kevan Shokat, whose scientific explorations have formed the academic basis of a slew of startups in the biotech hub. One of Shokat’s PhD students in the lab, Nicholas Hertz, co-founded Mitokinin using their lab work on PINK1 suggesting that amping up its activity could play an important role in regulating the mitochondrial dysfunction contributing to Parkinson’s disease pathogenesis and progression.

With stars aligned and cash in re­serve, Bob Nelsen's Re­silience plans a makeover at 2 new fa­cil­i­ty ad­di­tions to its drug man­u­fac­tur­ing up­start

Bob Nelsen’s new, state-of-the-art drug manufacturing initiative is taking shape.

Just 3 months after gathering $800 million of launch money, a dream team board and a plan to shake up a field where he found too many bottlenecks and inefficiencies for the era of Covid-19, Resilience has snapped up a pair of facilities now in line for a retooling.

The company has acquired a 310,000-square-foot plant in Boston from Sanofi along with a 136,000-square-foot plant in Ontario to add to a network which CEO Rahul Singhvi says is just getting started on building his company’s operations up. The Sanofi deal comes with a contract to continue manufacturing one of its drugs.

Roivant par­lays a $450M chunk of eq­ui­ty in biotech buy­out, grab­bing a com­pu­ta­tion­al group to dri­ve dis­cov­ery work

New Roivant CEO Matt Gline has crafted an all-equity upfront deal to buy out a Boston-based biotech that has been toiling for several years now at building a supercomputing-based computational platform to design new drugs. And he’s adding it to the Erector set of science operations that are being built up to support their network of biotech subsidiaries with an eye to growing the pipeline in a play to create a new kind of pharma company.

Af­ter bail­ing on Covid-19 vac­cines, Mer­ck will team up with J&J to pro­duce its shot as part of un­usu­al Big Phar­ma pact

Merck took a big gamble when it opted to jump into the Covid-19 vaccine race late, and made an equally momentous decision to back out in late January. Now, looking to chip in on the effort, Merck reportedly agreed to team up with one of the companies that has already crossed the finish line.

President Joe Biden on Tuesday is expected to announce a partnership between drugmakers Merck and Johnson & Johnson to jointly produce J&J’s recombinant protein Covid-19 vaccine that received the FDA’s emergency use authorization Saturday, the Washington Post reported.

The next big biotech su­per­star? Paul Sekhri has some thoughts on that

It occasionally occurs to Paul Sekhri that if they pull this off, his company will be on the front page of the New York Times and a lead story in just about every major news outlet on the planet. He tries not to dwell on it, though.

“I just want to be laser-focused on getting to that point,” Sekhri says, before acknowledging, “Yes, it absolutely crossed my mind.”

Sekhri, a longtime biopharma executive with tenures at Sanofi and Novartis, is now entering year three as CEO of eGenesis, the biotech that George Church protégé Luhan Yang founded to genetically alter pigs so that they can be used for organ transplants. He led them through one megaround and has just closed another, raising $125 million from 17 different investors to push the first-ever (humanized) pig to human transplants into the clinic.

A 'love sto­ry': WuXi AppTec wraps UK-based CRO in­to its cell and gene ther­a­py unit

When WuXi AppTec, one of China’s largest contract research organizations, started working with UK-based Oxgene about a year ago, it was “love at first sight,” CEO David Chang jokes.

Oxgene, a roughly decade-old CRO focused on scalable gene therapy tech, began licensing some of their plasmid work to WuXi just over a year ago. And when that pilot went well, WuXi expressed interest in investing, Oxgene CEO Ryan Cawood said.

Fi­bro­Gen shares skid low­er as a sur­prise ad­comm rais­es risks on roxa OK

FibroGen will likely have to delay its US rollout for roxadustat once again.

In an unexpected move, the FDA is convening its Cardiovascular and Renal Drugs Advisory Committee to review the NDA in an advisory committee meeting. The date is yet to be confirmed.

Just a few weeks ago, SVB Leerink analyst Geoffrey Porges predicted that the roxa approval could come ahead of the PDUFA date on March 20 — effusive despite already being let down once by the FDA’s extension of its review back in December. AstraZeneca, which is partnered with FibroGen on the chronic kidney disease-related anemia drug, disclosed regulators had requested further clarifying analyses of clinical data.
