Se­nior R&D ex­ec Sue Dil­lon jumps ship at J&J, launch­es mys­tery biotech start­up Aro with Cen­tyrins tech

Two for­mer ex­ec­u­tive heavy­weights at John­son & John­son have left the phar­ma gi­ant to launch a rather stealthy start­up called Aro Bio­ther­a­peu­tics – and they are start­ing out with some drug tech they’re al­ready close­ly fa­mil­iar with.

Karyn O’Neil

The com­pa­ny’s pres­i­dent and CEO is Sue Dil­lon, an R&D cham­pi­on and the ex-glob­al ther­a­peu­tic area head for im­munol­o­gy in the Janssen Phar­ma­ceu­ti­cals unit of J&J. Her co-founder and CSO is Karyn O’Neil, the for­mer ven­ture leader for Cen­tyrex, an­oth­er J&J unit.

The com­pa­ny is fly­ing deeply un­der the radar, with vir­tu­al­ly no web pres­ence aside from Bio­Cen­tu­ry’s news of Aro’s launch. Dil­lon did not im­me­di­ate­ly re­spond to our re­quest for more in­fo on the com­pa­ny, but here’s what we do know:

Aro is work­ing with a nov­el class of al­ter­na­tive scaf­fold mol­e­cules called Cen­tyrins, which can be en­gi­neered to bind to tar­get pro­teins with an in­ter­face of sim­i­lar size to those used by an­ti­bod­ies. This tech was be­ing de­vel­oped at Cen­tyrex (the J&J unit where O’Neil, the in­ven­tor of the Cen­tyrin plat­form, pre­vi­ous­ly worked), and that plat­form has been li­censed out to two can­cer com­pa­nies: On­tario-based Fu­sion Phar­ma­ceu­ti­cals and San Diego-based Po­sei­da Ther­a­peu­tics, the lat­ter of which was housed in J&J’s San Diego JLABs back in 2015. Fu­sion is de­vel­op­ing Cen­tyrin-based al­pha-par­ti­cle ra­dio­ther­a­peu­tics, and Po­sei­da is de­vel­op­ing au­tol­o­gous T cell and NK cell ther­a­pies that ex­press Cen­tyrins or Cen­tyrin CAR mol­e­cules.

Ac­cord­ing to J&J: “Aro Bio­ther­a­peu­tics has ex­clu­sive world­wide rights to the Cen­tyrin IP es­tate with Janssen re­served fields in­clud­ing and pur­suant to Fu­sion Phar­ma­ceu­ti­cals Inc. and Po­sei­da Ther­a­peu­tics Inc.”

Dil­lon and O’Neil join the great mi­gra­tion out of Big Phar­ma and in­to small biotech, as es­teemed R&D lead­ers in­creas­ing­ly seek op­por­tu­ni­ties else­where. O’Neil re­tired from her role at Cen­tyrex back in De­cem­ber, ac­cord­ing to her LinkedIn, to co-found Aro with Dil­lon. As for Dil­lon, she left her role at J&J around the same time.

New­man Yeild­ing

“Hav­ing sup­port­ed Sue for many years dur­ing her tenure here at Janssen/J&J, I have a great deal of re­spect for her lead­er­ship, vi­sion and de­ter­mi­na­tion to con­tin­ue to make a dif­fer­ence in pa­tients’ lives and in the life sci­ences in­dus­try,” wrote J&J’s glob­al ther­a­peu­tic area com­mu­ni­ca­tion leader Bri­an Ken­ney in an email.

Ken­ney not­ed that Dil­lon re­tired from J&J af­ter a “16 year suc­cess­ful ca­reer” with the com­pa­ny.

Ken­ney says New­man Yeild­ing, head of im­munol­o­gy de­vel­op­ment at Janssen, is lead­ing the ther­a­peu­tic area for im­munol­o­gy un­til the com­pa­ny finds a re­place­ment for Dil­lon.

The Fac­tors Dri­ving a Rapid Evo­lu­tion of Gene & Cell Ther­a­py and CAR-T Clin­i­cal Re­search in APAC

APAC is the fastest growing region globally for cell & gene therapy trials representing more than a third of all cell & gene studies globally, with China leading in the region. 

APAC is the leading location globally for CAR-T trials with China attracting ~60% of all CAR-T trials globally between 2015-2022. The number of CAR-T trials initiated by Western companies has rapidly increased in recent years (current CAGR of about 60%), with multiple targets being explored including CD19, CD20, CD22, BCMA, CD30, CD123, CD33, CD38, and CD138.

EMA warns of short­ages of two Boehringer heart drugs due to a spike in de­mand

The EMA is putting EU member states on alert over the shortage of two drugs that counter heart attacks due to an uptick in demand.

On Friday, the EMA sent out a warning that two Boehringer Ingelheim drugs are experiencing a shortage: Actilyse and Metalyse. The drugs are used as emergency treatments for adults experiencing acute myocardial infarction, or a heart attack, by dissolving blood clots that have formed in the blood vessels.

The End­points 11: The top pri­vate biotechs in pur­suit of new drugs. Push­ing the en­ve­lope with pow­er­ful new tech­nolo­gies

Right around the beginning of the year, we got a close-up look at what happens after a boom ripples through biotech. The crash of life sciences stocks in Q1 was heard around the world.

In the months since, we’ve seen the natural Darwinian down cycle take effect. Reverse mergers made a comeback, with more burned out shells to go public at a time IPOs and road shows are out of favor. And no doubt some of the more recent arrivals on the investing side of the business are finding greener pastures.

As­traZeneca, Mer­ck cull one Lyn­parza in­di­ca­tion in heav­i­ly pre­treat­ed ovar­i­an can­cer pa­tients

Just one day after blockbuster Lynparza got access to another indication in China, its Big Pharma owners have decided to withdraw it in certain patients after reviewing Phase III data.

The two companies that work together on Lynparza decided to recall one of the indications several weeks ago in a specific type of ovarian cancer, Lynparza’s first indication when it was first FDA-approved in 2014. Initial data showed that rates of overall survival in patients with at least three rounds of chemo before getting on the PARP inhibitor were lower than in patients with less previous chemo treatment.

Fu­ji­film con­tin­ues CD­MO ex­pan­sion, break­ing ground on $435M UK site

Fujifilm’s CDMO arm, Fujifilm Diosynth, has been on a roll this month as the company has recently broken ground on a major project in Europe and it appears to be keeping up the momentum.

Fujifilm Diosynth announced that it has kicked off an expansion project for its microbial manufacturing facility at its campus in the town of Billingham, UK, in the northeast of England.

The 20,000 square-foot, £400 million ($435 million) expansion will add clean rooms, purification suites and a packing area along with more space for the manufacturing itself.

Should SCO­TUS hear Am­gen's Repatha case? So­lic­i­tor gen­er­al says no

Back in April, Amgen said it was encouraged by the solicitor general’s anticipated review of its Supreme Court petition to rehear a Repatha patent case. They’re likely much less optimistic about the outcome now.

Solicitor General Elizabeth Prelogar wrote in a recent 27-page brief that Amgen’s arguments “lack merit and further review is not warranted.”

The case traces back to a suit filed in 2014 against Sanofi and Regeneron’s Praluent, which ended up beating Amgen’s PCSK9 blockbuster Repatha to market by a month just a year later.

The End­points 11: Fire­side chat with No­bel Prize lau­re­ate Phil Sharp

The following Q&A has been edited for length and clarity.

John Carroll:

We’ve had a chance to talk a little bit before here about some of the things that you’ve done. Just really remarkably, a lot of the things that you’ve done early in your career puts you in the path with some amazing science that has had an absolutely huge impact in terms of what we’re seeing now on drug development and some of the new technologies that are coming out here, and not only the new technologies, but also some of the most remarkable people ever.

Klick Health gath­ers biotech and phar­ma lu­mi­nar­ies to dis­cuss in­dus­try in­no­va­tions, in­vest­ments and fu­ture

At Klick Health’s first Ideas Exchange conference with biotech and pharma industry insiders since before the pandemic began, it was no surprise many conversations included Covid topics. Yet while vaccines and treatments were discussed, so too were the effects on drug development, federal responses, health inequities — and what to do now and next.

George Yancopoulos, chief scientist and cofounder of Regeneron, opened the conference responding to a question from Acorda CEO Ron Cohen about the spotlight on the industry during Covid and some of the “flak” biopharma has taken in the past.
