The PC­SK9 of NASH? Re­gen­eron and Al­ny­lam join forces to tack­le a promis­ing tar­get for se­vere liv­er dis­eases

The Re­gen­eron Ge­net­ics Cen­ter $REGN rou­tine­ly sifts through a moun­tain of se­quenc­ing da­ta. And every now and then, the re­searchers there will pan out a glit­ter­ing find­ing that looks like it could rank right up there with PC­SK9.

Here’s one.

John Maraganore

This evening, in a study pub­lished in the New Eng­land Jour­nal of Med­i­cine, they are point­ing to one such dis­cov­ery that they be­lieve has some big im­pli­ca­tions for se­vere liv­er dis­eases, in­clud­ing the Holy Grail of NASH. And with­out a log­i­cal an­ti­body strat­e­gy to put in­to play — giv­en an in­tra­cel­lu­lar tar­get in the spot­light — they’ve en­list­ed an ex­pe­ri­enced crew at Al­ny­lam to bring their RNAi gene si­lenc­ing plat­form in­to the game to find the most ef­fi­cient way to pro­vide the key to coun­ter­ing a raft of ail­ments.

“We ob­vi­ous­ly saw the da­ta and we were blown away,” says Al­ny­lam $AL­NY CEO John Maraganore, who’s now in wait-and-see mode as their lead drug patisir­an rolls up to an Au­gust PDU­FA date. “This tar­get  — HSD17B13 — from a hu­man ge­net­ics per­spec­tive it re­al­ly is the  PC­SK9 of NASH.”

Aris Baras

Re­gen­eron prides it­self on mov­ing ag­gres­sive­ly when they find some­thing promis­ing for clin­i­cal de­vel­op­ment. And in Al­ny­lam, they feel they are work­ing with close kin in that re­spect.

“These guys at Al­ny­lam have a sim­i­lar ap­proach and track record,” says Aris Baras, head of the RGC. And he feels this tar­get de­serves speed and care, which in­spired a 50/50 deal on re­search costs and any com­mer­cial po­ten­tial that comes out of the pre­clin­i­cal align­ment.

How fast can Al­ny­lam move here? “We’re not giv­ing guid­ance,” says Maraganore, but he says you shouldn’t be sur­prised if there’s a pro­gram in the clin­ic next year. (Yes, that is fast.)

The deal, he adds, calls for shared eco­nom­ics in de­vel­op­ment, with Al­ny­lam do­ing the crit­i­cal ear­ly de­vel­op­ment and Re­gen­eron pick­ing up the late-stage work. That will be their first RNAi study of their own, says Maraganore, but there’s no re­al mys­tery in how that works. And they’ll stay close­ly in­volved through­out.

The study of hu­man ge­net­ics in these cen­ters is be­gin­ning to have a re­al im­pact on R&D ef­fi­cien­cy, says Baras. And this project in par­tic­u­lar, he be­lieves, high­lights the promise of the field in quick­ly ze­ro­ing in on a vi­able drug pro­gram.

By set­ting up a large pile of ge­net­ic da­ta on thou­sands of pa­tients with liv­er dis­ease and com­par­ing it with se­quenc­ing da­ta on a group of tens of thou­sands of healthy peo­ple, Baras tells me, the re­searchers at Re­gen­eron’s ge­net­ics arm nar­rowed down pos­si­ble ge­net­ic trig­gers for dis­ease to a loss-of-func­tion ge­net­ic vari­a­tion in HSD17B13.

Ful­ly shut down by the vari­a­tion, the in­ves­ti­ga­tors found that eclips­ing the gene re­duced en­zy­mat­ic ac­tiv­i­ty:

— Cut­ting the risk of al­co­holic cir­rho­sis by 73%.

— Low­er­ing the risk of non­al­co­holic cir­rho­sis by 49%.

— And cut­ting the risk of al­co­holic liv­er dis­ease by 53%, and non­al­co­holic liv­er dis­ease by 30%, with an as­so­ci­at­ed re­duc­tion in risk of NASH.

Re­gen­eron is al­so go­ing af­ter some small mol­e­cule pro­grams in the process.

“We think this is big bi­ol­o­gy and there are dif­fer­ent shots on goal with dif­fer­ent modal­i­ties,” says Baras.

We’ll stay fo­cused here at End­points on this one to see whether it lives up to the pre­clin­i­cal promise. Tra­di­tion sug­gests that any pro­gram that goes in­to the clin­ic will have at best around a 1 in 10 shot at an ap­proval. Ge­net­ics aims to change those odds for the bet­ter.

2023 Spot­light on the Fu­ture of Drug De­vel­op­ment for Small and Mid-Sized Biotechs

In the context of today’s global economic environment, there is an increasing need to work smarter, faster and leaner across all facets of the life sciences industry.  This is particularly true for small and mid-sized biotech companies, many of which are facing declining valuations and competing for increasingly limited funding to propel their science forward.  It is important to recognize that within this framework, many of these smaller companies already find themselves resource-challenged to design and manage clinical studies themselves because they don’t have large teams or in-house experts in navigating the various aspects of the drug development journey. This can be particularly challenging for the most complex and difficult to treat diseases where no previous pathway exists and patients are urgently awaiting breakthroughs.

Q&A: Bris­tol My­er­s' Kris­ten Hege on cell ther­a­py, can­cer pa­tients and men­tor­ing the next gen­er­a­tion

Kristen Hege leads Bristol Myers Squibb’s early oncology discovery program carrying on from the same work at Celgene, which was acquired by BMS in 2019. She’s known for her early work in CAR-T, having pioneered the first CAR-T cell trial for solid tumors more than 25 years ago.

However, the eminent physician-scientist is more than just a drug developer mastermind. She’s also a practicing physician, mother to two young women, an avid backpacker and intersecting all those interests — a champion of young women and people of color in STEM and life sciences.

Gos­samer’s Fa­heem Has­nain de­fends a round of pos­i­tive PAH da­ta as a clear win. But can these PhII re­sults stand up to scruti­ny?

Gossamer Bio $GOSS posted a statistically significant improvement for its primary endpoint in the key Phase II TORREY trial for lead drug seralutinib on Tuesday morning. But CEO Faheem Hasnain has some explaining to do on the important secondary of the crucial six-minute walk distance test — which will be the primary endpoint in Phase III — as the data on both endpoints fell short of expectations, missing one analyst’s bar on even modest success.

US sup­ports ex­ten­sion for Covid-19 IP waiv­er de­ci­sion

After much debate, the US government is now calling for a deadline extension to discuss a controversial potential IP waiver for Covid-19 diagnostics and therapeutics.

Over the last five months, the Office of the United States Trade Representative said it has consulted with members of Congress, public health advocates, organized labor groups, academics, think tanks, companies and trade associations on the WTO’s recent TRIPS agreement, which established a 5-year waiver of certain patent requirements on Covid-19 vaccines.

Mar­ket­ingRx roundup: Phar­mas lay off Twit­ter ads for an­oth­er week; WPP un­cov­ers LGBTQ+ mar­ket­ing find­ings

When Twitter’s new owner Elon Musk tweeted this weekend, “Just a note to thank advertisers for returning to Twitter,” he likely wasn’t talking about big pharma companies. The vast majority of the top spending pharma advertisers had not returned last week, according to updated tracking data Pathmatic for Endpoints News.

Only three pharma advertisers spent any money at all, which is about the same as the past several weeks. AstraZeneca rejoined the active advertiser list, although at $700 spent hardly worth a personal Musk expression of gratitude. GSK remained active with $3,500 spent ad much lower than its previous spending, according to the Pathmatics data. Only Bayer spent any significant amount in advertising, with $244,000 spent last week, but that’s a considerable drop from almost $500,000 spent on OTC, prescription and corporate Twitter ads in each of the previous two weeks.

Rick Modi, Affinia Therapeutics CEO

Ver­tex-part­nered gene ther­a­py biotech Affinia scraps IPO plans

Affinia Therapeutics has ditched its plans to go public in a relatively closed-door market that has not favored Nasdaq debuts for the drug development industry most of this year. A pandemic surge in 2020 and 2021 opened the doors for many preclinical startups, which caught Affinia’s attention and gave the gene therapy biotech confidence in the beginning days of 2022 to send in its S-1.

But on Friday, Affinia threw in the S-1 towel and concluded now is not the time to step onto Wall Street. The biotech has put out few public announcements since the spring of this year. Endpoints News picked the startup as one of its 11 biotechs to watch last year.

Bounc­ing from ma­jor set­back, Sum­mit hands out $500M cash for can­cer drug — thanks to a loan from bil­lion­aire CEO

After hitting a dead end with Summit Therapeutics’ lead program, Bob Duggan has found the drug that he believes will usher into a compelling second act. So compelling, in fact, that it involves $500 million cash — and he’s taking money out of his own pocket to fund the deal.

Striking a partnership with Akeso Therapeutics out of China, Summit is bringing in a bispecific antibody that blocks both PD-1 and VEGF called ivonescimab. Akeso, which has a PD-1/CTLA-4 bispecific approved in China, has already taken ivonescimab into multiple clinical trials, including a Phase III in lung cancer.

Scoop: Aval­on, MPM back new CNS biotech with sci­en­tif­ic chops from Astel­las

A preclinical central nervous system biotech is in the works in La Jolla, CA, and the drug developer has reeled in capital from a syndicate of investors, Endpoints News has learned.

Arialys Therapeutics filed incorporation documents in the Golden State last December and applied its name for trademark protection with the US Patent and Trademark Office the week prior to that. Paperwork with the SEC also outlines plans to offer up equity in exchange for $55 million.

Ed­i­tas re­ports ear­ly-stage da­ta from two pa­tients in sick­le cell dis­ease

One company is moving forward in its bid to make a cell therapy for sickle cell disease viable — and after previous setbacks, including a hold earlier this year, execs are touting some really early data.

Editas Medicine announced Tuesday morning that it had positive safety and efficacy data from two patients in a Phase I/II trial investigating EDIT-301, a cell therapy candidate that Editas developed. Safety was measured in both patients, and efficacy data are from only the first patient dosed.
