Nim­bus picks 4 pre­clin­i­cal tar­gets for the next chap­ter of its pi­o­neer­ing com­pu­ta­tion­al drug dis­cov­ery work

Big name part­ner­ships were crit­i­cal for Nim­bus Ther­a­peu­tics’ first decade. With a head-turn­ing $1.2 bil­lion — $600 mil­lion of which were paid with­in months — deal from Gilead and a re­turn­ing cus­tomer in Cel­gene, the biotech emerged as a pro­lif­ic pi­o­neer of com­pu­ta­tion­al chem­istry and struc­ture-based drug dis­cov­ery while the in­dus­try went through a seis­mic shift in its think­ing of the role that al­go­rithms play in en­gi­neer­ing new ther­a­pies.

As the sec­ond of the ini­tial batch of pro­grams en­ter the clin­ic, Nim­bus is un­veil­ing the head­ings that will de­fine what it calls its sec­ond chap­ter.

Their team of 20-plus sci­en­tists has iden­ti­fied four new tar­gets — AMP­Kβ2, CTPS1, Cbl-b and WRN — which they have been prob­ing with aca­d­e­m­ic col­lab­o­ra­tors and ex­perts at Schrödinger. And this time around, they plan to keep all four in-house for at least a lit­tle longer, fo­cus­ing on re­cruit­ing new staffers and friend­ly re­searchers rather than buy­ers.

At the same time, Nim­bus has dropped its STING ef­forts af­ter a slew of biotechs reached for it and came up emp­ty.

“One of the com­pli­ments we’ve been paid by our peers in the broad­er drug dis­cov­ery and de­vel­op­ment com­mu­ni­ty has been in our abil­i­ty to se­lect re­al­ly in­ter­est­ing tar­gets that are quite com­pelling,” Jeb Keiper — the for­mer BD chief who took over as CEO from Don Nichol­son less than two years ago — told End­points News. “We care a lot about be­ing able to do that.”

Aside from the usu­al sus­pects in tar­get se­lec­tion, such as ge­net­ic val­i­da­tion and med­ical need, Nim­bus zoomed in­to ones for which a se­lec­tive, struc­ture-based ap­proach is par­tic­u­lar­ly help­ful, CSO Pe­ter Tum­mi­no said.

Pe­ter Tum­mi­no

In AMPK (AMP-ac­ti­vat­ed pro­tein ki­nase), that means find­ing ac­ti­va­tors se­lec­tive for the β2 sub­unit, which could trans­late in­to a bet­ter safe­ty pro­file as meta­bol­ic drugs. Sim­i­lar­ly, the chal­lenge in CTP is to find com­pounds se­lec­tive for the S-1 iso­form. Cbl-b (Cbl pro­to-onco­gene B) is an E3 ubiq­ui­tin lig­ase — a nat­ur­al pro­tein de­grad­er — that’s gar­nered at­ten­tion from both small com­pa­nies like Nurix and big ones like Roche. Fi­nal­ly, the goal with WRN (Wern­er syn­drome ATP-de­pen­dent he­li­case) is to come up with a new treat­ment op­tion for tu­mors vul­ner­a­ble to dis­rup­tions in DNA re­pair.

“What isn’t new is we’re look­ing for small mol­e­cule agents,” he said.

Al­though these are tar­gets of high in­ter­est, he added, much is still un­known about their struc­tures, and Nim­bus is work­ing with lead­ing bi­ol­o­gists to elu­ci­date them with tech­niques like cryo-EM and crys­tal­log­ra­phy.

These are “not things you can sim­ply out­source to con­tract re­search groups,” Keiper added. “You re­al­ly are do­ing fun­da­men­tal aca­d­e­m­ic dis­cov­ery work.” That’s the kind of spe­cial sauce — mix­ing dyed in the wool drug dis­cov­ery vet­er­ans with com­pu­ta­tion­al ex­perts — that Nim­bus be­lieves will keep it go­ing for many years more.

Scoop: Boehringer qui­et­ly shut­ters a PhII for one of its top drugs — now un­der re­view

Boehringer Ingelheim has quietly shut down a small Phase II study for one of its lead drugs.

The private pharma player confirmed to Endpoints News that it had shuttered a study testing spesolimab as a therapy for Crohn’s patients suffering from bowel obstructions.

A spokesperson for the company tells Endpoints:

Taking into consideration the current therapeutic landscape and ongoing clinical development programs, Boehringer Ingelheim decided to discontinue our program in Crohn’s disease. It is important to note that this decision is not based on any safety findings in the clinical trials.

Alex­ion puts €65M for­ward to strength­en its po­si­tion on the Emer­ald Isle

Ireland has been on a roll in 2022, with several large pharma companies announcing multimillion-euro projects. Now AstraZeneca’s rare disease outfit Alexion is looking to get in on the action.

Alexion on Friday announced a €65 million ($68.8 million) investment in new and enhanced capabilities across two sites in the country, including at College Park in the Dublin suburb of Blanchardstown and the Monksland Industrial Park in the central Irish town of Athlone, according to the Industrial Development Agency of Ireland.

State bat­tles over mifepri­s­tone ac­cess could tie the FDA to any post-Roe cross­roads

As more than a dozen states are now readying so-called “trigger” laws to kick into effect immediate abortion bans following the overturning of Roe v. Wade on Friday, these laws, in the works for more than a decade in some states, will likely kick off even more legal battles as states seek to restrict the use of prescription drug-based abortions.

Since Friday’s SCOTUS opinion to overturn Americans’ constitutional right to an abortion after almost 50 years, reproductive rights lawyers at Planned Parenthood and other organizations have already challenged these trigger laws in Utah and Louisiana. According to the Guttmacher Institute, other states with trigger laws that could take effect include Arkansas, Idaho, Kentucky, Mississippi, Missouri, North Dakota, Oklahoma, South Dakota, Tennessee, Texas, and Wyoming.

Deborah Dunsire, Lundbeck CEO

Af­ter a 5-year re­peat PhI­II so­journ, Lund­beck and Ot­su­ka say they're fi­nal­ly ready to pur­sue OK to use Rex­ul­ti against Alzheimer's ag­i­ta­tion

Five years after Lundbeck and their longtime collaborators at Otsuka turned up a mixed set of Phase III data for Rexulti as a treatment for Alzheimer’s dementia-related agitation, they’ve come through with a new pivotal trial success they believe will finally put them on the road to an approval at the FDA. And if they’re right, some analysts believe they’re a short step away from adding more than $500 million in annual sales for the drug, already approved in depression and schizophrenia.

A Mer­ck part­ner is sucked in­to the fi­nan­cial quag­mire as key lender calls in a note

Another biotech standing on shaky financial legs has fallen victim to the bears.

Merck partner 4D Pharma has reported that a key lender, Oxford Finance, shoved the UK company into administration after calling in a $14 million loan they couldn’t immediately make good on. Trading in their stock was halted with a market cap that had fallen to a mere £30 million.

“Despite the very difficult prevailing market conditions,” 4D reported on Friday, the biotech had been making progress on finding some new financing and turned to Oxford with an alternative late on Thursday and then again Friday morning.

Biden and G7 na­tions of­fer funds for vac­cine and med­ical prod­uct man­u­fac­tur­ing project in Sene­gal

Amidst recently broader vaccine manufacturing initiatives from the EU and European companies, the G7 summit in the mountains of Bavaria has brought about some positive news for closing vaccine and medical product manufacturing gaps around the globe.

According to a statement from the White House, the G7 leaders have formally launched the partnership for global infrastructure, PGII. The effort will aim to mobilize hundreds of billions of dollars to deliver infrastructure projects in several sectors including the medical and pharmaceutical manufacturing space.

Fed­er­al judge de­nies Bris­tol My­er­s' at­tempt to avoid Cel­gene share­hold­er law­suit

Some Celgene shareholders aren’t happy with how Bristol Myers Squibb’s takeover went down.

On Friday, a New York federal judge ruled that they have a case against the pharma giant, denying a request to dismiss allegations that it purposely slow-rolled Breyanzi’s approval to avoid paying out $6.4 billion in contingent value rights (CVR).

When Bristol Myers put down $74 billion to scoop up Celgene back in 2019, liso-cel — the CAR-T lymphoma treatment now marketed as Breyanzi — was supposedly one of the centerpieces of the deal. After going back and forth on negotiations for about six months, BMS put $6.4 billion into a CVR agreement that required an FDA approval for Zeposia, Breyanzi and Abecma, each by an established date.

Take­da, Ar­row­head spot­light da­ta from small tri­al show­ing RNAi works in a rare liv­er con­di­tion

Almost two years after Takeda wagered $300 million cash to partner with Arrowhead on an RNAi therapy for a rare disease, the companies are spelling out Phase II data that they believe put them one step closer to their big dreams.

In a small, open label study involving only 16 patients who had liver disease associated with alpha-1 antitrypsin deficiency (AATD), Arrowhead’s candidate — fazirsiran, previously ARO-AAT — spurred substantial reductions in accumulated mutant AAT protein in the liver, a hallmark of the condition. Investigators also tracked improvements in symptoms, with seven out of 12 who received the high, 200 mg dose seeing regression of liver fibrosis.

No stranger to gene ther­a­py woes, Astel­las runs in­to an­oth­er safe­ty-re­lat­ed clin­i­cal hold

Astellas Pharma, which has been at the forefront of uncovering the risks associated with gene therapies delivered by adeno-associated viruses, must take another safety alarm head-on.

The FDA has slapped a clinical hold on Astellas’ Phase I/II trial of a gene therapy candidate for late-onset Pompe disease, after investigators flagged a serious case of peripheral sensory neuropathy.

It marks the latest in a streak of setbacks Astellas has encountered since making a splashy entry into the gene therapy space with its $3 billion buyout of Audentes. But the lead program, AT132 for the treatment of X-linked myotubular myopathy (XLMTM), had to be halted more than once after a total of four patients died in the trial — and the scientific community still doesn’t have all the answers of what caused the deaths.
