Third Rock, GV back Broad spin­out Cel­sius in bid to de­vel­op pre­ci­sion meds for au­toim­mune dis­ease

Third Rock is team­ing up with Google’s ven­ture arm to back a gene ther­a­py start­up step­ping out to­day with $65 mil­lion in new mon­ey. As you might ex­pect with GV’s in­volve­ment, the new ven­ture has a tech­nol­o­gy twist, and it might have its hands on some­thing big for the au­toim­mune world.

Are you ready for a game of buzz­word bin­go? The start­up, called Cel­sius Ther­a­peu­tics, is us­ing new tech in ge­net­ic se­quenc­ing (check) — and a pro­pri­etary ma­chine learn­ing (check) al­go­rithm (check) — to tack­le pre­ci­sion meds (check) for can­cer (check) and au­toim­mune dis­ease. I’ll break that down for you lat­er.

The tech­nol­o­gy the com­pa­ny is built on was li­censed from the Broad In­sti­tute based on the work of Aviv Regev and Vi­jay Kuchroo (both found­ing sci­en­tists at Cel­sius), in­clud­ing non-ex­clu­sive li­cens­es to sin­gle-cell se­quenc­ing tech and ex­clu­sive li­cens­es to ear­ly-stage drug pro­grams.

The com­pa­ny’s co-founder and pres­i­dent, Christoph Lengauer (a Third Rock ven­ture part­ner), tells me Cel­sius has a few things that give it an edge: a mas­sive amount of an­i­mal and hu­man da­ta to work with, a ma­chine-learn­ing al­go­rithm to make sense of that da­ta, and a new tech­nol­o­gy to se­quence sin­gle cells rather than whole genomes.

Our body has tril­lions of cells, each with ge­net­ic in­for­ma­tion stored in­side. The sets of genes vary in dif­fer­ent cell types, de­ter­min­ing a cell’s func­tion — and some­times — the code be­hind dis­ease. Hom­ing in on sin­gle cells could help re­searchers bet­ter un­der­stand the in­di­vid­ual cells and their in­ter­ac­tions that cause dis­ease, per­haps lead­ing to bet­ter ther­a­pies down the road.

When com­par­ing sin­gle cell se­quenc­ing with whole genome se­quenc­ing, Lenguaer used an anal­o­gy about mak­ing smooth­ies with fruit.

“If you put straw­ber­ries and ki­wis in a blender, the col­or of your smooth­ie will be pink be­cause it’s the dom­i­nant cell pop­u­la­tion,” Lengauer said. “Any­thing re­lat­ed to the ki­wi would be lost. That’s whole genome se­quenc­ing. With this anal­o­gy, sin­gle cell se­quenc­ing would al­low you to see the in­di­vid­ual fruits in the smooth­ie. And if some­thing was rot­ten, you could pin­point the in­di­vid­ual fruit that’s gone bad.”

Of course, we’re not talk­ing of straw­ber­ries and ki­wis, but of cells that are caus­ing dis­ease and the genes that trig­ger their mal­func­tion. Cel­sius be­lieves this tech could be the key to bring pre­ci­sion med­i­cines to au­toim­mune dis­eases for the first time.

“Many dis­eases are dri­ven by the com­bined dys­func­tion of sev­er­al spe­cif­ic cell types, and the in­ter­ac­tions be­tween them,” said Regev, the MIT pro­fes­sor who co-found­ed Cel­sius, in a state­ment. “With tra­di­tion­al ge­nom­ic se­quenc­ing, we can­not iden­ti­fy these in­di­vid­ual con­tri­bu­tions — we on­ly see the av­er­age and can miss out key crit­i­cal caus­es. But for the first time, with the ap­proach­es dis­cov­ered by our team, where we com­bine mas­sive datasets of un­prece­dent­ed size and com­plex­i­ty with so­phis­ti­cat­ed ma­chine learn­ing al­go­rithms, we are able to dis­tin­guish the spe­cif­ic cells, among many oth­ers, that play a key role in dis­ease and iden­ti­fy the genes that are trig­ger­ing their mal­func­tion. We be­lieve our ap­proach will al­low us to more ef­fi­cient­ly iden­ti­fy spe­cif­ic tar­gets for treat­ing dis­eases in spe­cif­ic pa­tients and ul­ti­mate­ly de­vel­op med­i­cines for those tar­gets.”

Us­ing this ap­proach, the Broad In­sti­tute has un­cov­ered “a hand­ful” of tar­gets in au­toim­mune con­di­tions and can­cer. Lengauer said Cel­sius hopes to reach proof of con­cept in the next five years, and the Se­ries A should take them at least part­way to­ward that goal.

While Third Rock led the re­cent round, GV par­tic­i­pat­ed along with Her­itage Provider Net­work, Cas­din Cap­i­tal, Alexan­dria Ven­ture In­vest­ments and oth­ers.

The com­pa­ny, which has been op­er­at­ing in stealth mode for the past two years, em­ploys 15 peo­ple at its Cam­bridge head­quar­ters in Kendall Square.

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?

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.

Christine Bunt, Robert Langer. Verseau

Armed with Langer tech and $50M, Verseau hails new check­point drugs un­leash­ing macrophages against can­cer

The rising popularity of CD47 has propelled the “don’t-eat-me” signal to household name status in the immuno-oncology world: By blocking that protein, the theory goes, one can stop cancer cells from fooling macrophages. But just as PD-(L)1 merely represents the most fruitful of all checkpoints regulating T cells, Verseau Therapeutics is convinced that CD47 is one of many regulators one can modulate to stir up or tame the immune system.

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, AP

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.

CSL ac­cus­es ri­val Pharm­ing of par­tic­i­pat­ing in a scheme to rip off IP on HAE while re­cruit­ing se­nior R&D staffer

Pharming has landed in the middle of a legal donnybrook after recruiting a senior executive from a rival R&D team at CSL. The Australian pharma giant slapped Pharming with a lawsuit alleging that the Dutch biotech’s new employee, Joseph Chiao, looted a large cache of proprietary documents as he hit the exit. And they want it all back.
Federal Judge Juan Sanchez in the Eastern District Pennsylvania court issued an injunction on Tuesday prohibiting Chiao from doing any work on HAE or primary immune deficiency in his new job and demanding that he return any material from CSL that he may have in his possession. And he wants Pharming to tell its employees not to ask for any information on the forbidden topics.
For its part, Pharming fired off an indignant response this morning denying any involvement in extracting any kind of IP from CSL, adding that it’s cooperating in the internal probe that CSL has underway.

Eli Lil­ly’s first PhI­II show­down for their $1.6B can­cer drug just flopped — what now?

When Eli Lilly plunked down $1.6 billion in cash to acquire Armo Biosciences a little more than a year ago, the stars seemed aligned in its favor. The jewel in the crown they were buying was pegilodecakin, which had cleared the proof-of-concept stage and was already in a Phase III trial for pancreatic cancer.

And that study just failed.

Lilly reported this morning that their cancer drug flopped on overall survival when added to FOLFOX (folinic acid, 5-FU, oxaliplatin), compared to FOLFOX alone among patients suffering from advanced pancreatic cancer.
