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.

CSL lands FDA ap­proval for he­mo­phil­ia B gene ther­a­py, sets $3.5M list price

The FDA has approved the world’s first gene therapy for hemophilia B, ushering into the market a treatment that’s historic in both what it promises to do and how much it will cost.

CSL will be marketing the drug, Hemgenix, at a list price of $3.5 million — which sets a new record for the most expensive single-use gene therapy in the US.

In a statement provided to Endpoints News, the Australian company noted that the current costs of treating people with moderate to severe hemophilia B can be significant over a lifetime. By some estimates, healthcare systems could spend more than $20 million per person.

Andrew Phillips, Nexo Therapeutics CEO

Scoop: Ver­sant, NEA launch new biotech helmed by ex-CEO of pro­tein de­grad­er C4 Ther­a­peu­tics

Long-time biotech venture firms Versant and New Enterprise Associates are backing a new startup run by former C4 Therapeutics chief executive Andrew Phillips.

The fledgling biotech has raised at least $30 million so far, according to paperwork filed with the SEC this week. The round could balloon to $60 million.

Phillips, who left protein degradation startup C4 in 2020 to be a managing director at Cormorant Asset Management, is running the show of the new venture as president, the SEC filing outlines. He also served as interim CEO of Cormorant-backed and Hansoh Pharmaceutical-partnered Blossom Bioscience last year.

Biggest drug com­pa­nies halt­ed Twit­ter ad buys af­ter Lil­ly in­sulin spoof

Almost all of the drug industry’s biggest advertisers cut their spending on Twitter to zero or near-zero over the last two weeks amid worries about impersonation of their brands by pranksters and the future of the social media company.

Among 18 of the biggest pharmaceutical advertisers in the US market, 12 cut their Twitter ad spending to nothing for the week beginning Nov. 14, according to Pathmatics, which tracks data on prescription drug ad spending as well as general corporate advertising. The list of drugmakers cutting spending to zero includes Merck, AstraZeneca, Eli Lilly, Novartis, Pfizer and others.

Rob Davis, Merck CEO

Up­dat­ed: No Seagen here: 'Do more' means a small $1.35B pur­chase of Ima­go for Mer­ck

Merck is making an acquisition, the Big Pharma announced before Monday’s opening bell. No, Seagen is not entering the fold, as had been speculated for quarters.

Folding under Merck’s wings will be Pfizer-backed Imago BioSciences. For nearly a year, Merck CEO Rob Davis has been saying the pharma giant needs to “do more” on the business development front after its 2021 $11.5 billion acquisition of Acceleron.

MIT re­searchers re­veal DNA "Paste" tech be­hind lat­est gene edit­ing start­up

MIT scientists have developed a tool that they say can insert large gene sequences where they want in the genome.

In a paper published Thursday in Nature Biotechnology, MIT fellows Omar Abudayyeh, Jonathan Gootenberg and colleagues detail a technology they call PASTE, which they say can potentially be used to insert long strands of DNA and treat genetic diseases caused by many different mutations, such as cystic fibrosis and Leber congenital amaurosis, a rare eye disorder that causes blindness.

J&J's Spra­va­to pulls a PhI­II win against Sero­quel XR in treat­ment-re­sis­tant de­pres­sion

A day before Thanksgiving, J&J’s Janssen has a new cut of Phase III Spravato data to be grateful for.

The pharma giant announced on Wednesday that its nasal spray, also known as esketamine, beat extended-release quetiapine, previously sold by AstraZeneca as Seroquel XR, in treatment-resistant depression (TRD). Of 676 adults, a significantly higher number of patients on Spravato were able to achieve remission and avoid relapse after 32 weeks, according to J&J.

Dermavant Sciences' first consumer TV ad for its Vtama psoriasis med shows people ready for a new topical treatment.

Roivant’s Der­ma­vant de­buts first-ever TV com­mer­cial for pso­ri­a­sis cream Vta­ma

Dermavant Sciences has been marketing its first product, psoriasis med Vtama, to dermatologists for months, but on Tuesday it rolled out its first consumer campaign. The debut DTC effort including a streaming TV commercial encourages patients to a “Topical Uprising” in a nod to Vtama being a topical cream.

In the new commercial, a swell of people discards scarves and jacket coverings, gathering in the street to converge on a pharmacy to demand a steroid-free prescription. A moment of levity follows when a pharmacist says, “You know you can just talk to your doctor, right?” The gathered crowds collectively says, “Oh.”
