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.”

Con­quer­ing a silent killer: HDV and Eiger Bio­Phar­ma­ceu­ti­cals

Hepatitis delta, also known as hepatitis D, is a liver infection caused by the hepatitis delta virus (HDV) that results in the most severe form of human viral hepatitis for which there is no approved therapy.

HDV is a single-stranded, circular RNA virus that requires the envelope protein (HBsAg) of the hepatitis B virus (HBV) for its own assembly. As a result, hepatitis delta virus (HDV) infection occurs only as a co-infection in individuals infected with HBV. However, HDV/HBV co-infections lead to more serious liver disease than HBV infection alone. HDV is associated with faster progression to liver fibrosis (progressing to cirrhosis in about 80% of individuals in 5-10 years), increased risk of liver cancer, and early decompensated cirrhosis and liver failure.
HDV is the most severe form of viral hepatitis with no approved treatment.
Approved nucleos(t)ide treatments for HBV only suppress HBV DNA, do not appreciably impact HBsAg and have no impact on HDV. Investigational agents in development for HBV target multiple new mechanisms. Aspirations are high, but a functional cure for HBV has not been achieved nor is one anticipated in the forseeable future. Without clearance of HBsAg, anti-HBV investigational treatments are not expected to impact the deadly course of HDV infection anytime soon.

No­var­tis is ax­ing 150 ear­ly dis­cov­ery jobs as CNI­BR shifts fo­cus to the de­vel­op­ment side of R&D

Novartis is axing some 150 early discover jobs in Shanghai as it swells its staff on the drug development side of the equation in China. And the company is concurrently beefing up its investment in China’s fast-growing biotech sector with a plan to add to its investments in local VCs.

Democratic presidential candidate, U.S. Sen. Elizabeth Warren (D-MA) speaks during the Nevada Democrats' "First in the West" event at Bellagio Resort & Casino on November 17, 2019 in Las Vegas, Nevada (Getty Images)

Eliz­a­beth War­ren pro­pos­es us­ing com­pul­so­ry li­cens­ing, an­titrust ac­tions to break bio­phar­ma’s con­trol of drug pric­ing — and here are the block­busters she’s tar­get­ing first

Nancy Pelosi’s drug pricing bill may have sparked some industrial strength headaches on the money side of biopharma, but Elizabeth Warren seems determined to become biopharma’s Nightmare on Pennsylvania Avenue.
Warren, one of the top-ranked candidates for the Democratic presidential nomination backing Medicare for all, is circulating a new plan that promises to break the industry’s grip on drug prices — and she has some very specific examples of how she would do it.
The Warren plan would rely on the federal government’s compulsory licensing powers to seize the IP of blockbuster drugs like Truvada and Harvoni to provide them at a fraction of what Gilead sells them for in the US. And she would throw some antitrust actions in as needed to rein in the price of Humira, AbbVie’s cash cow that continues to dominate the list of the most profitable therapeutics on the market.
Notably, she plans to rely on the powers already vested in the federal government, rather than suggest remedies that would require the assent of a deeply divided Congress.
In addition to the blockbusters on the list, Warren sends a clear signal that the same tactics would be used to beef up the supply of cheap antibiotics, as needed. And the same action could befall any other therapy patients can’t afford.

Mer­ck’s $1B cash gam­ble pays off with a sur­pris­ing PhI­II car­dio suc­cess for Bay­er’s heart drug veri­ciguat

More than 3 years after Merck stepped up and paid $1 billion in cold, hard cash to gain the US commercial rights to Bayer’s high-risk heart drug vericiguat in a broad-ranging cardio alliance, the partners say their Phase III study has come through with promising data and a date with regulators.
We don’t have the data, and won’t until they put it out at an upcoming scientific session, but Merck touted the results, saying that their big Phase III VICTORIA study hit the primary endpoint  — with vericiguat combined with available therapies reducing “the risk of the composite endpoint of heart failure hospitalization or cardiovascular death in patients with worsening chronic heart failure with reduced ejection fraction (HFrEF) compared to placebo when given in combination with available heart failure therapies.”
Depending on the hard data, and how it breaks out with the combinations used, this drug could pose a threat to Novartis’ blockbuster drug Entresto, currently at $1.6 billion while analysts expect peak sales to hit $4 billion.
The drug is a soluble guanylate cyclase (sGC) stimulator, which Bayer and Merck have had high hopes for. Evidently, so did cardiologists. Cowen’s last analysis set potential sales at $400 million in 2024, but that number could go up significantly now.
Cowen’s Steve Scala noted this morning:
Vericiguat could be a lucrative product for Merck, and one with potentially under-appreciated value. At Cowen’s Therapeutics Conference in September 2019, 80% of specialists anticipated a positive result from VICTORIA whereas only 51% of investors shared this optimism.
Investigators recruited more than 5,000 patients at more than 600 centers in 42 countries for this study — one of the most expensive propositions in R&D. Millions of people in the US suffer from heart failure with reduced ejection fraction when the failing heart fails to contract properly to eject blood into the system. Bayer holds ex-US rights to the drug and also stands to earn cash from the $1.1 billion in milestones Merck agreed on for their collaboration.
Remarkably, the drug was pushed into Phase III despite failing the mid-stage trial — though investigators flagged a success at the high dose of 10 mg. In VICTORIA, researchers started patients at 2.5 mg and then titrated up to 5 and then 10 mg.

Alk­er­mes forges $950M biotech buy­out deal in a bold bet on an ear­ly-stage CNS drug plat­form

Alkermes $ALKS is investing $100 million cash and committing up to $850 million more in milestones in a big wager on a very early-stage CNS discovery platform. And the biotech is adding $20 million more to fund next year’s new research work on the platform it’s acquiring in today’s buyout with an eye to expanding the research work in oncology.

The biotech, helmed by Richard Pops, is buying Rodin Therapeutics, which had focused early on Alzheimer’s disease. Pops’ buyout, though, isn’t focused solely on the most troublesome sector in pharma R&D.

Amarin emerges from an ex­pert pan­el re­view with a clear en­dorse­ment for Vas­cepa and high odds of suc­cess when the FDA weighs in for­mal­ly

Several FDA experts who gathered Thursday to consider the landmark approval of Vascepa to reduce cardio events in an at-risk population voiced their unease about various aspects of the efficacy and safety data, or ultimately the population it should be used to treat. But the overwhelming belief that the data pointed to the drug’s benefit and clearly outweighed risks carried the day for Amarin.

The panel voted unanimously (16 to 0) to support the company’s positive data presentation — backing an OK for expanding the label to include reducing cardio risk. The vote points Amarin $AMRN down a short path to a formal decision by the FDA, with the odds heavily in its favor. Chances are the rest of the questions about the future of this drug will be hashed out in the label’s small print.

In rare po­lit­i­cal for­ay, top biotech in­vestors urge Con­gress to re­ject drug pric­ing bill

Thirteen of the top biotech venture capitalists in the country wrote a letter last week warning lawmakers that if Congress passes a drug pricing bill House Speaker Nancy Pelosi has put before lawmakers, they won’t be able to invest in biomedical research at their current rate, and patients will suffer.

“If policies such as those included within H.R. 3, the Lower Drug Costs Now Act, are passed, our ability to continue to invest in future biomedical innovation will be severely constrained, thus crushing the hopes of millions of patient waiting for the next breakthroughs to treat or cure their cancers, rare genetic diseases, Alzheimer’s, or other serious and life-threatening conditions,” they wrote in a letter addressed to the highest-ranking Democrats and Republicans in the House and Senate and acquired by Endpoints News. 

Dicer­na scores broad, 'rest of liv­er' deal with No­vo Nordisk, bag­ging $225M in cash to hit some 30 tar­gets with RNAi plat­form

Turns out Dicerna wasn’t done with deals yet after locking in $200 million upfront from Roche for a hepatitis B cocktail two weeks ago.

Novo Nordisk has signed on as the latest partner to its GalXC RNAi platform, handing over $175 million in cash to claim any and all targets of interest in liver-related cardio-metabolic diseases that are not already reserved in previous pacts. The Danish drugmaker — which has signaled its interest to expand considerably beyond its core diabetes franchise into areas like NASH — is also purchasing $50 million worth of Dicerna’s equity at a 25% premium of $21.93 per share. More research payments and milestones extending to the billions are on the line.
