Drug dis­cov­ery in HD: Ox­ford spin­of­f's mass spec­trom­e­try ap­proach scores fresh fund­ing

The tech­nol­o­gy used to de­tect ex­plo­sives at air­ports — mass spec­trom­e­try — is be­ing pi­lot­ed as an en­gine for drug dis­cov­ery.

Mass spec­trom­e­try is a tool de­signed to mea­sure with pro­found ac­cu­ra­cy the mass of a sin­gle mol­e­cule. Typ­i­cal­ly, mass spec­trom­e­ters can be used to iden­ti­fy un­known com­pounds, to quan­ti­fy known com­pounds, and to de­ter­mine the struc­ture and chem­i­cal prop­er­ties of mol­e­cules.

Us­ing this in­for­ma­tion to de­vel­op drugs, ver­sus us­ing tra­di­tion­al cell-based as­says is an ap­proach pi­o­neered by Car­ol Robin­son, the first fe­male pro­fes­sor of chem­istry at the Uni­ver­si­ty of Ox­ford. Along­side her for­mer stu­dents, Robin­son found­ed OMass Ther­a­peu­tics to move it for­ward in the field of mem­brane tar­gets, in­clud­ing GPCRs.

On Mon­day, the Ox­ford spin­off un­veiled £27.5 mil­lion in ad­di­tion­al Se­ries A fi­nanc­ing from Syn­cona, Ox­ford Sci­ences In­no­va­tion (OSI), and the Uni­ver­si­ty of Ox­ford, bring­ing its to­tal haul to £41.5 mil­lion.

“It’s drug dis­cov­ery in high de­f­i­n­i­tion…it’s all about re­veal­ing the pic­ture with high­er res­o­lu­tion. And it’s about high con­tent da­ta. The rea­son mass spec­trom­e­try is in­ter­est­ing in drug dis­cov­ery is that the con­tent that you get from the da­ta is much high­er res­o­lu­tion than through a cell-based as­say,” OMass chief Ros Dee­gan told End­points News.

“So in a cell-based as­say, you’re ef­fec­tive­ly an­swer­ing on­ly the ques­tion that you asked, where­as, in na­tive mass spec­trom­e­try, it’s a bio­phys­i­cal ap­proach.”

The ma­jor­i­ty of ex­ist­ing ther­a­peu­tics tar­get mem­brane pro­tein — ac­ces­si­ble on the sur­face of cells — to mod­i­fy cel­lu­lar sig­nal­ing. In con­trast to tra­di­tion­al cell-based as­says, the mass spec­trom­e­try ap­proach of­fers ‘high de­f­i­n­i­tion’ in­sight in­to un­der­stand­ing mem­brane pro­tein bi­ol­o­gy, Dee­gan not­ed.

The plat­form pro­vides ac­cess to dif­fer­ent chem­i­cal start­ing points be­cause bio­phys­i­cal ap­proach­es tend to point to­ward dif­fer­ent chem­istry — as they are not bi­ased to spe­cif­ic types of chem­istry through the use of cell-based as­says, she said. “Cell-based as­says tend to put you in lipophilic, quite of­ten large lipophilic com­pounds.”

If the ap­proach is shown to work, it could serve to short­en drug dis­cov­ery time­frames.

“Ul­ti­mate­ly the com­pa­ny aims to use high de­f­i­n­i­tion tech­nolo­gies to ef­fi­cient­ly ac­cess can­di­dates with a greater PoS (prob­a­bil­i­ty of suc­cess) in high-val­ue ar­eas, there­fore sig­nif­i­cant­ly short­en­ing the drug dis­cov­ery time­line for small mol­e­cules,” said Lach­lan MacK­in­non, prin­ci­pal at OSI in an email to End­points.

OMass in­tends to not just iden­ti­fy mol­e­cules of in­ter­est but to take them through to the mar­ket them­selves. It has three pro­grams at the mo­ment — al­though they are far from be­ing ready for the clin­ic.

The cap­i­tal in­jec­tion will give OMass — which is fo­cus­ing on im­munol­o­gy and ge­net­i­cal­ly de­fined dis­eases out­side of im­munol­o­gy — just over two years of run­way and will be used to shep­herd its lead pro­gram in­to pre­clin­i­cal de­vel­op­ment.

The Price of Re­lief: Ex­plor­ing So­lu­tions to the Ris­ing Costs of On­col­o­gy Drugs

In 2020, The National Cancer Institute estimated about 1.8 million new cases of cancer diagnosed in the United States, while the costs associated with treatment therapies continued to escalate. Given the current legislative climate on drug pricing, it’s never been more important to look at the evolution of drug pricing globally and control concerns of sustainable and affordable treatments in oncology.

A $3B+ peak sales win? Pfiz­er thinks so, as FDA of­fers a tardy green light to its JAK1 drug abroc­i­tinib

Back in the fall of 2020, newly crowned Pfizer chief Albert Bourla confidently put their JAK1 inhibitor abrocitinib at the top of the list of blockbuster drugs in the late-stage pipeline with a $3 billion-plus peak sales estimate.

Since then it’s been subjected to serious criticism for the safety warnings associated with the class, held back by a cautious FDA and questioned when researchers rolled out a top-line boast that their heavyweight contender had beaten the champ in the field of atopic dermatitis — Dupixent — in a head-to-head study.

Rob Califf ad­vances as Biden's FDA nom­i­nee, with a close com­mit­tee vote

Rob Califf’s second confirmation process as FDA commissioner is already much more difficult than his near unanimous confirmation under the Obama administration.

The Senate Health Committee on Thursday voted 13-8 in favor of advancing Califf’s nomination to a full Senate vote. Several Democrats voted against Califf, including Sen. Bernie Sanders and Sen. Maggie Hassan. Several other Democrats who aren’t on the committee, like West Virginia’s Joe Manchin and Ed Markey of Massachusetts, also said Thursday that they would not vote for Califf. Markey, Hassan and Manchin all previously expressed reservations about the prospect of Janet Woodcock as an FDA commissioner nominee too.

Bio­gen vows to fight CM­S' draft cov­er­age de­ci­sion for Aduhelm be­fore April fi­nal­iza­tion

Biogen executives made clear in an investor call Thursday they are not preparing to run a new CMS-approved clinical trial for their controversial Alzheimer’s drug anytime soon.

As requested in a draft national coverage decision from CMS earlier this week, Biogen and other anti-amyloid drugs will need to show “a meaningful improvement in health outcomes” for Alzheimer’s patients in a randomized, placebo-controlled trial to get paid for their drugs, rather than just the reduction in amyloid plaques that won Aduhelm its accelerated approval in June.

CRO own­er pleads guilty to ob­struct­ing FDA in­ves­ti­ga­tion in­to fal­si­fied clin­i­cal tri­al da­ta

The co-owner of a Florida-based clinical research site pleaded guilty to lying to an FDA investigator during a 2017 inspection, revealing that she falsely portrayed part of a GlaxoSmithKline pediatric asthma study as legitimate, when in fact she knew that certain data had been falsified, the Department of Justice said Wednesday.

Three other employees — Yvelice Villaman Bencosme, Lisett Raventos and Maytee Lledo — previously pleaded guilty and were sentenced in connection with falsifying data associated with the trial at the CRO Unlimited Medical Research.

Can­cer pow­er­house As­traZeneca rolls the dice on a $75M cash bet on a buzzy up­start in the on­col­o­gy field

After establishing itself in the front ranks of cancer drug developers and marketers, AstraZeneca is putting its scientific shoulder — and a significant amount of cash — behind the wheel of a brash new upstart in the biotech world.

The pharma giant trumpeted news this morning that it is handing over $75 million upfront to ally itself with Scorpion Therapeutics, one of those biotechs that was newly birthed by some top scientific, venture and executive talent and bequeathed with a fortune by way of a bankroll to advance an only hazily explained drug platform. And they are still very much in the discovery and preclinical phase.

‘Skin­ny la­bels’ on gener­ics can save pa­tients mon­ey, re­search shows, but re­cent court de­ci­sions cloud fu­ture

New research shows how generic drug companies can successfully market a limited number of approved indications for a brand name drug, prior to coming to market for all of the indications. But several recent court decisions have created a layer of uncertainty around these so-called “skinny” labels.

While courts have generally allowed generic manufacturers to use their statutorily permitted skinny-label approvals, last summer, a federal circuit court found that Teva Pharmaceuticals was liable for inducing prescribers and patients to infringe GlaxoSmithKline’s patents through advertising and marketing practices that suggested Teva’s generic, with its skinny label, could be employed for the patented uses.

How a tiny Swiss lab and two old blood sam­ples cre­at­ed one of the on­ly ef­fec­tive drugs against Omi­cron (and why we have so lit­tle of it)

Exactly a decade before a novel coronavirus broke out in Wuhan, Davide Corti — a newly-minted immunologist with frameless glasses and a quick laugh — walked into a cramped lab on the top floor of an office building two hours outside Zurich. He had only enough money for two technicians and the ceiling was so low in parts that short stature was a job requirement, but Corti believed it’d be enough to test an idea he thought could change medicine.
