Bris­tol-My­ers claims the lead in a race to de­vel­op a TYK2 drug, hop­ing to dis­rupt a huge mar­ket for an­ti-in­flam­ma­to­ries

Bris­tol-My­ers Squibb’s TYK2 team has been show­ing off some Phase II da­ta they be­lieve puts them in the run­ning for leader of a small but promi­nent pack of de­vel­op­ers look­ing to ad­vance a new class of an­ti-in­flam­ma­to­ries that aim at pen­e­trat­ing some very big mar­kets.

As pub­lished in the New Eng­land Jour­nal of Med­i­cine and pre­sent­ed at the 27th Eu­ro­pean Acad­e­my of Der­ma­tol­ogy and Ven­erol­o­gy Con­gress in Paris, Bris­tol-My­ers’ ef­fort for BMS-986165 pro­duced some com­pet­i­tive re­sults in a key mid-stage study for mod­er­ate-to-se­vere plaque pso­ri­a­sis — a packed field where JAK in­hibitors have been mak­ing waves.

By nar­row­ly tar­get­ing TYK2 — and leav­ing the oth­er JAK fam­i­ly tar­gets out — with an al­losteric ap­proach, as op­posed to ATP bind­ing, the Bris­tol-My­ers group say they were able to safe­ly pro­duce a range of com­pet­i­tive PASI75 clear­ance rates of 67% to 75% for the three high­est dos­es of the oral drug in the dose-rang­ing study.

“From my per­spec­tive the clin­i­cal da­ta we have bears out the strat­e­gy we set out to de­liv­er right in the ear­ly stages of the dis­cov­ery pro­gram,” says John Throup, the de­vel­op­ment lead for TYK2, who of­fered a pre­view of the da­ta that was on dis­play Wednes­day, along with dis­cov­ery chemist Ryan Moslin.

This was an in-house pro­gram from the very be­gin­ning at Bris­tol-My­ers. And they’re tak­ing it all the way through, look­ing to trip up pro-in­flam­ma­to­ry cy­tokine re­cep­tors, in­clud­ing the hot tar­get IL-23, IL-12 and Type 1 in­ter­fer­ons with what they be­lieve is a clear­ly safe oral drug look­ing to dis­tin­guish it­self from a very big — and grow­ing — field of ri­vals.

The drug is al­ready in two Phase III stud­ies for pso­ri­a­sis, which joint­ly re­cruit­ed 1,600 pa­tients with a planned read-out in mid-2020. And they’re ex­pand­ing the work in­to Crohn’s and lu­pus, keep­ing an eye on oth­er tar­gets they could add as well

“Pa­tients don’t need an­oth­er non-spe­cif­ic JAK in­hibitor,” adds Throup, not­ing the safe­ty is­sues that have come up for the class, which in­cludes baric­i­tinib and Xel­janz. And they be­lieve that they’ve al­so tak­en the right path in the clin­ic by avoid­ing the ac­tive bind­ing site and tar­get­ing the reg­u­la­to­ry do­main in TYK2.

Of course, this drug still has to sur­vive the big Phase III chal­lenge in much larg­er pa­tient pop­u­la­tions that are de­signed to spot­light any small safe­ty is­sue. And ri­val de­vel­op­ment groups fo­cused on TYK2 for Cel­gene and its part­ners at Nim­bus, which is still pre­clin­i­cal, as well as Pfiz­er — which a spokesper­son tells me has mapped four Phase II stud­ies for PF-06700841— aren’t like­ly to let Bris­tol-My­ers pass un­chal­lenged.

In the mean­time, Ab­b­Vie is hus­tling ahead with its reg­u­la­to­ry re­view of the IL-23 drug risankizum­ab for pso­ri­a­sis, con­vinced they have the da­ta need­ed to field a megablock­buster. And there are more in­jecta­bles like Cosen­tyx — and fil­go­tinib from Gilead and Gala­pa­gos — which is al­ready well es­tab­lished. 

Bring­ing a safe, ef­fec­tive oral drug could dis­rupt that fast-chang­ing mar­ket­place. But this is one bat­tle of the gi­ants where every­one will be fierce­ly de­fend­ing their turf.

Hal Barron, GSK's president of R&D and CSO, speaks to Endpoints News founder and editor John Carroll in London at Endpoints' #UKBIO19 summit on October 8, 2019

[Video] Cel­e­brat­ing tri­al fail­ures, chang­ing the cul­ture and al­ly­ing with Cal­i­for­nia dream­ers: R&D chief Hal Bar­ron talks about a new era at GSK

Last week I had a chance to sit down with Hal Barron at Endpoints’ #UKBIO19 summit to discuss his views on R&D at GSK, a topic that has been central to his life since he took the top research post close to 2 years ago. During the conversation, Barron talked about changing the culture at GSK, a move that involves several new approaches — one of which involves celebrating their setbacks as they shift resources to the most promising programs in the pipeline. Barron also discussed his new alliances in the Bay Area — including his collaboration pact with Lyell, which we covered here — frankly assesses the pluses and minuses of the UK drug development scene, and talks about his plans for making GSK a much more effective drug developer.

Med­ical an­i­ma­tion: Mak­ing it eas­i­er for the site and the pa­tient to un­der­stand

Medical animation has in recent years become an increasingly important tool for conveying niche information to a varied audience, particularly to those audiences without expertise in the specialist area. Science programmes today, for example, have moved from the piece-to-camera of the university professor explaining how a complex disease mechanism works, to actually showing the viewer first-hand what it might look like to shrink ourselves down to the size of an ant’s foot, and travel inside the human body to witness these processes in action. Effectively communicating a complex disease pathophysiology, or the novel mechanism of action of a new drug, can be complex. This is especially difficult when the audience domain knowledge is limited or non-existent. Medical animation can help with this communication challenge in several ways.
Improved accessibility to visualisation
Visualisation is a core component of our ability to understand a concept. Ask 10 people to visualise an apple, and each will come up with a slightly different image, some apples smaller than others, some more round, some with bites taken. Acceptable, you say, we can move on to the next part of the story. Now ask 10 people to visualise how HIV’s capsid protein gets arranged into the hexamers and pentamers that form the viral capsid that holds HIV’s genetic material. This request may pose a challenge even to someone with some virology knowledge, and it is that inability to effectively visualise what is going on that holds us back from fully understanding the rest of the story. So how does medical animation help us to overcome this visualisation challenge?

FDA ex­pands Xofluza ap­proval as Roche strug­gles to catch loom­ing flu mar­ket

As a potentially powerful flu season looms, so does a big test for Roche and its new flu drug, Xofluza. The Swiss giant just got a small boost in advance of that test as the FDA expanded Xofluza’s indication to include patients at high risk of developing flu-related complications.

Xofluza (baloxavir marboxil) was approved last October in the US, the first landmark flu drug approval in 20 years and a much-needed green light for a company that had watched its leading flu drug Tamiflu get eaten alive by generics. Like its predecessor, the pill offered a reduction in flu symptoms but not a cure.

EMA backs sev­en ther­a­pies, in­clud­ing Mer­ck­'s Ebo­la vac­cine

The first-ever Ebola vaccine is on the precipice of approval after the European Medicine’s Agency (EMA) backed the Merck product in this week’s roster of recommendations.

The drugmaker $MRK began developing the vaccine, christened Ervebo, during the West African outbreak that occurred between 2014 and 2016, killing more than 11,000.

The current outbreak in the Democratic Republic of Congo (DRC) has shown case fatality rates of approximately 67%, the agency estimated. Earlier this year, the WHO declared the outbreak — which so far has infected more than 3,000 people — a public health emergency of international concern.

Ronald Herb­st fol­lows Med­Im­mune ex­o­dus to Pyx­is CSO post; Jeff God­dard to suc­ceed CEO of AIT Bio­science

→ The outflow of top execs from MedImmune continues to fill the leadership ranks of smaller biotechs. The latest to take off is Ronald Herbst, the head of oncology research, who’s assuming the CSO post at Pyxis Oncology.  

Herbst was part of the old MedImmune organization AstraZeneca CEO Pascal Soriot restructured earlier this year, reorganizing the company and eliminating the storied subsidiary as a separate organization.

Mi­rati preps its first look at their KRAS G12C con­tender, and they have to clear a high bar for suc­cess

If you’re a big KRAS G12C fan, mark your calendars for October 28 at 4:20 pm EDT.

That’s when Mirati $MRTX will unveil its first peek at the early clinical data available on MRTX849 in presentations at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston.

Mirati has been experiencing the full effect of a rival’s initial success at targeting the G12C pocket found on KRAS, offering the biotech some support on the concept they’re after — and biotech fans a race to the top. Amgen made a big splash with its first positive snapshot on lung cancer, but deflated sky-high expectations as it proved harder to find similar benefits in other types of cancers.

Sean Park­er helps cre­ate a CRISPRed cell ther­a­py 2.0 play — and he’s got a high-pro­file set of lead­ers on the team

You can rack up one more high-profile debut effort in the wave of activity forming around cell therapy 2.0. It’s another appealing Bay Area group that’s attracted some of the top hands in the business to a multi-year effort to create a breakthrough. And they have $85 million in hand to make that first big step to the clinic.

Today it’s Ken Drazan and the team at South San Francisco-based ArsenalBio that are coming from behind the curtain for a public bow, backed by billionaire Sean Parker and a collection of investors that includes Beth Seidenberg’s new venture investment operation based in LA.
Drazan — a J&J Innovation vet with a long record of entrepreneurial endeavors — exited the stage in 2018 when his last mission ended as he stepped aside as president of Grail. It wasn’t long, though, before he was helping out with a business plan for ArsenalBio that revolved around the work of a large group of interconnected scientists supported by the Parker Institute for Cancer Immunology.
