Pro­tein degra­da­tion 2.0? Third Rock sinks $56M in­to Cedil­la's un­usu­al ap­proach

Third Rock Ven­tures is trot­ting out the lat­est play­er in the hot space of pro­tein degra­da­tion, in­fus­ing the new start­up with $56 mil­lion in launch mon­ey to find out if its un­con­ven­tion­al ap­proach to junk­ing pro­teins works bet­ter than its ri­vals.

The up­start goes by Cedil­la Ther­a­peu­tics, and it’s en­ter­ing a field of drug de­vel­op­ment that’s pick­ing up a lot of steam this year. The con­cept be­hind the emerg­ing space is sim­ple enough: where pro­tein in­hi­bi­tion has led to some ad­vanced med­i­cines, de­grad­ing pro­teins could prove a more fruit­ful so­lu­tion. The ap­proach could have ma­jor ben­e­fits over tra­di­tion­al small-mol­e­cule strate­gies, in­clud­ing the po­ten­tial to cut down sys­temic drug ex­po­sure and the abil­i­ty to tack­le tar­get pro­teins once con­sid­ered un­drug­gable.

Many play­ers in pro­tein degra­da­tion are tack­ling the field by hi­jack­ing the ubiq­ui­tin process, es­sen­tial­ly tag­ging dis­ease-caus­ing pro­teins for de­struc­tion by re­cruit­ing an E3 lig­ase to the tar­get, which sends the pro­tein to the cell’s nat­ur­al “garbage dis­pos­al.” It’s a smart idea, but it’s al­so quite com­plex to build these mol­e­cules. Ear­ly pi­o­neers in the pro­tein degra­da­tion space are tak­ing this ap­proach now, in­clud­ing Arv­inas, Kymera, and C4 Ther­a­peu­tics, among oth­ers.

Cedil­la is tak­ing aim at a dif­fer­ent av­enue, the com­pa­ny’s CEO Alexan­dra (San­dra) Glucks­mann tells me.

“What we’re try­ing to do is up­stream of that whole process,” she said. “In­stead of start­ing with a tech­nol­o­gy and then hav­ing to find a tar­get — and be­ing lim­it­ed by the tech we have — we are in­stead start­ing with a tar­get of in­ter­est and ap­ply­ing dif­fer­ent method­olo­gies to de­grade it.”

Third Rock has been gun­ning away on this idea for months now, re­cruit­ing Glucks­mann, a found­ing em­ploy­ee and the ex-COO of Ed­i­tas, to serve as en­tre­pre­neur-in-res­i­dence at the ven­ture firm six months ago (with plans to put her at the helm of Cedil­la straight away). Glucks­mann said the com­pa­ny al­ready em­ploys 12 peo­ple.

In short, Cedil­la is us­ing more tra­di­tion­al small mol­e­cule drugs to desta­bi­lize dis­ease-caus­ing pro­teins ahead of the ubiq­ui­ti­na­tion process. Once the pro­teins are un­sta­ble, the cell rec­og­nizes them as dys­func­tion­al and toss­es them in the garbage dis­pos­al.

One way the com­pa­ny is go­ing about this is by map­ping out the chem­i­cal bonds be­tween pro­teins. The goal, Glucks­mann says, is to “or­phan” a tar­get pro­tein by dis­rupt­ing its bonds with oth­er pro­teins, tip­ping the tar­get in­to an un­sta­ble state.

Cedil­la is al­ready run­ning 8 ear­ly-stage pro­grams in par­al­lel, Glucks­mann said, us­ing the new funds from Third Rock to ID which can­di­dates they’ll take to the clin­ic. The com­pa­ny thinks this tech could be have wide­spread ap­pli­ca­tions.

“We are ini­tial­ly fo­cused on on­col­o­gy tar­gets,” said Cedil­la’s CSO Bri­an Jones. “We al­so be­lieve our small mol­e­cule ap­proach is broad­ly ap­plic­a­ble, for ex­am­ple to ac­cess tar­gets in the cen­tral ner­vous sys­tem.”

Roivant par­lays a $450M chunk of eq­ui­ty in biotech buy­out, grab­bing a com­pu­ta­tion­al group to dri­ve dis­cov­ery work

New Roivant CEO Matt Gline has crafted an all-equity upfront deal to buy out a Boston-based biotech that has been toiling for several years now at building a supercomputing-based computational platform to design new drugs. And he’s adding it to the Erector set of science operations that are being built up to support their network of biotech subsidiaries with an eye to growing the pipeline in a play to create a new kind of pharma company.

Tar­get­ing a Po­ten­tial Vul­ner­a­bil­i­ty of Cer­tain Can­cers with DNA Dam­age Re­sponse

Every individual’s DNA is unique, and because of this, every patient responds differently to disease and treatment. It is astonishing how four tiny building blocks of our DNA – A, T, C, G – dictate our health, disease, and how we age.

The tricky thing about DNA is that it is constantly exposed to damage by sources such as ultraviolet light, certain chemicals, toxins, and even natural biochemical processes inside our cells.¹ If ignored, DNA damage will accumulate in replicating cells, giving rise to mutations that can lead to premature aging, cancer, and other diseases.

NK cell ther­a­py play­er Arti­va makes some more noise, pulling in $120M Se­ries B less than a month af­ter Mer­ck deal

Not even one month after Big Pharma took notice of Artiva when Merck signed a collaboration worth nearly $2 billion in milestones, the off-the-shelf NK cell biotech already has its next big fundraise.

Artiva returns from the venture well Friday with a $120 million Series B round, money they will use to get their first program into the clinic and to file INDs for another two candidates. The raise marks the latest development in a rapidly expanding footprint for Artiva, which, in addition to the Merck deal last month, has now raised almost $200 million since its Series A last June.

UP­DAT­ED: Mer­ck takes a swing at the IL-2 puz­zle­box with a $1.85B play for buzzy Pan­dion and its au­toim­mune hope­fuls

When Roger Perlmutter bid farewell to Merck late last year, the drugmaker perhaps best known now for sales giant Keytruda signaled its intent to take a swing at early-stage novelty with the appointment of discovery head Dean Li. Now, Merck is signing a decent-sized check to bring an IL-2 moonshot into the fold.

Merck will shell out roughly $1.85 billion for Pandion Pharmaceuticals, a biotech hoping to gin up regulatory T cells (Tregs) to treat a range of autoimmune disorders, the drugmaker said Thursday.

Covid-19 roundup: Mer­ck­'s $356M sup­ply deal on hold as FDA asks for more da­ta; UK stud­ies of­fer more in­for­ma­tion on ef­fi­ca­cy of Pfiz­er/BioN­Tech vac­cine af­ter one dose

Merck is pushing back plans to supply the US government with a Covid-19 drug after the FDA asked for more data to support an emergency use authorization.

The antibody, MK-7110, had looked promising in a Phase III study conducted by OncoImmune before Merck came along and bought the biotech for $425 million. At the interim analysis, investigators looked at data from 203 patients and concluded that a single dose of the drug cut the risk of death or respiratory failure by more than 50% among severe patients. And those taking the drug had a 60% higher chance of improvement in clinical status compared to placebo.

The path to NASH: un­der­stand­ing the role of se­vere obe­si­ty in a com­plex, mul­ti-sys­tem dis­ease

Biotech Voices is a collection of exclusive opinion editorials from some of the leading voices in biopharma on the biggest industry questions today. Think you have a voice that should be heard? Reach out to senior editors Kyle Blankenship and Amber Tong.

We often think a person’s transition from a healthy to a diseased state is binary. But that’s often not the case. In reality, the onset of a disease is not something that occurs overnight, and the majority lie on a continuum that is impacted by a multitude of factors. Some of these factors are in a patient’s control. Others are not.

This is the case in nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), two of the most complex diseases that “live” on this proverbial continuum. The clinical onset of NAFLD — and ultimately NASH — is a complex process that is closely related to obesity, insulin resistance and impaired adipose tissue metabolism.

Why not? Sarep­ta’s third Duchenne MD drug sails to ac­cel­er­at­ed ap­proval

Sarepta may be running into some trouble with its next-gen gene therapy approach to Duchenne muscular dystrophy. But when it comes to antisense oligonucleotides, the well-trodden regulatory path is still leading straight to an accelerated approval for casimersen, now christened Amondys 45.

We just have to wait until 2024 to find out if it works.

Amondys 45’s approval was unceremonious, compared to its two older siblings. There was no controversy within the FDA over approving a drug based on a biomarker rather than clinical benefit, setting up a powerful precedent that still haunts acting FDA commissioner Janet Woodcock as biotech insiders weighed her potential permanent appointment; no drama like the FDA issuing a stunning rejection only to reverse its decision and hand out an OK four months later, which got more complicated after the scathing complete response letter was published; no anxious tea leaf reading or heated arguments from drug developers and patient advocates who were tired of having corticosteroids as their loved ones’ only (sometimes expensive) option.

Steve Cutler, Icon CEO (Icon)

In the biggest CRO takeover in years, Icon doles out $12B for PRA Health Sci­ences to fo­cus on de­cen­tral­ized clin­i­cal work

Contract research M&A had a healthy run in recent years before recently petering out. But with the market ripe for a big buyout and the Covid-19 pandemic emphasizing the importance of decentralized trials, Wednesday saw a tectonic shift in the CRO world.

Icon, the Dublin-based CRO, will acquire PRA Health Sciences for $12 billion in a move that will shake up the highest rungs of a fragmented market. The merger would combine the 5th- and 6th-largest CROs by 2020 revenue, according to Icon, and the merger will set the newco up to be the second-largest global CRO behind only IQVIA.
