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.”

Here comes the oral GLP-1 drug for di­a­betes — but No­vo Nordisk is­n't dis­clos­ing Ry­bel­sus price just yet

Novo Nordisk’s priority review voucher on oral semaglutide has paid off. The FDA approval for the GLP-1 drug hit late Friday morning, around six months after the NDA filing.

Rybelsus will be the first GLP-1 pill to enter the type 2 diabetes market — a compelling offering that analysts have pegged as a blockbuster drug with sales estimates ranging from $2 billion to $5 billion.

Ozempic, the once-weekly injectable formulation of semaglutide, brought in around $552 million (DKK 3.75 billion) in the first half of 2019.

As Nas­daq en­rolls the fi­nal batch of 2019 IPOs, how have the num­bers com­pared to past years?

IGM Biosciences’ upsized IPO haul, coming after SpringWorks’ sizable public debut, has revved up some momentum for the last rush of biotech IPOs in 2019.

With 39 new listings on the books and roughly two more months to go before winding down, Nasdaq’s head of healthcare listings Jordan Saxe sees the exchange marking 50 to 60 biopharma IPOs for the year.

“December 15 is usually the last possible day that companies will price,” he said, as companies get ready for business talks at the annual JP Morgan Healthcare Conference in January.

In­trex­on unit push­es back against claims its GM mos­qui­toes are mak­ing dis­ease-friend­ly mu­tants

When the hysteria of Zika transmission sprang into the American zeitgeist a few years ago, UK-based Oxitec was already field-testing its male Aedes aegypti mosquito, crafted to possess a gene engineered to obliterate its progeny long before maturation.

But when a group of independent scientists evaluated the impact of the release of these genetically-modified mosquitoes in a trial conducted by Oxitec in Brazil between 2013 and 2015, they found that some of the offspring had managed to survive — prompting them to speculate what impact the survivors could have on disease transmission and/or insecticide resistance.

Pur­due threat­ens to walk away from set­tle­ment, asks to pay em­ploy­ees mil­lions in bonus­es

There are two updates on the lawsuit against Purdue Pharma over its role in fueling the opioid epidemic, as the Sackler family threatens to walk away from their pledge to pay out $3 billion if a bankruptcy judge does not stop outstanding state lawsuits against them. At the same time, the company has asked permission to pay millions in bonuses to select employees.

Purdue filed for chapter 11 bankruptcy this week as part of its signed resolution to over 2,000 lawsuits. The deal would see the Sackler family that owns Purdue give $3 billion from their personal wealth and the company turned into a trust committed to curbing and reversing overdoses.

Genen­tech sub­mits a big plan to ex­pand its South San Fran­cis­co foot­print

The sign is still there, a quaint reminder of whitewashed concrete not 5 miles from Genentech’s sprawling, chrome-and-glass campus: South Francisco The Industrial City. 

The city keeps the old sign, first erected in 1923, as a tourist site and a kind of civic memento to the days it packed meat, milled lumber and burned enough steel to earn the moniker “Smokestack of the Peninsula.” But the real indication of where you are and how much has changed both in San Francisco and in the global economy since a couple researchers and investors rented out an empty warehouse 40 years ago comes in a far smaller blue sign, resembling a Rotary Club post, off the highway: South San Francisco, The Birthplace of Biotech.

While No­var­tis ban­ish­es Zol­gens­ma scan­dal scars — Bio­gen goes on a Spin­raza 'of­fen­sive'

While Novartis painstakingly works to mop up the stench of the data manipulation scandal associated with its expensive gene therapy for spinal muscular atrophy (SMA) Zolgensma— rival Biogen is attempting to expand the use of its SMA therapy, Spinraza. 

The US drugmaker $BIIB secured US approval for Spinraza for use in the often fatal genetic disease in 2016. The approval covered a broad range of patients with infantile-onset (most likely to develop Type 1) SMA.

UP­DAT­ED: Speak­er Nan­cy Pelosi to un­veil bill for fed­er­al­ly ne­go­ti­at­ed drug prices

After months of buzz from both sides of the aisle, Speaker Nancy Pelosi will today introduce her plan to allow the federal government to negotiate prices for 250 prescription drugs, setting up a showdown with a pharmaceutical industry working overtime to prevent it.

The need to limit drug prices is a rare point of agreement between President Trump and Democrats, although the president has yet to comment on the proposal and will likely face pressure to back a more conservative option or no bill at all. Republican Senator Chuck Grassley is reportedly lobbying his fellow party members on a more modest proposal he negotiated with Democratic Senator Ron Wyden in July.
