Can a rare im­mune cell of­fer the key to slow­ing down senes­cence? A Bay Area start­up looks to find out

For years, sci­en­tists have looked to curb ag­ing and chron­ic dis­eases by clear­ing de­funct cells with ir­repara­ble dam­age, al­so known as senes­cent cells. Drug­mak­ers like Bris­tol My­ers Squibb and Uni­ty Biotech­nol­o­gy have toiled over senolyt­ics to kill the stub­born cells. So when Robin Man­sukhani was told it could be done us­ing reawak­ened im­mune cells, he was in­trigued.

Senes­cence serves a pro­tec­tive func­tion. It oc­curs when cells are too dam­aged to keep di­vid­ing — for ex­am­ple, if they de­vel­op a can­cer­ous mu­ta­tion. But senes­cent cells al­so con­tribute to ag­ing and oth­er dis­eases, emit­ting tox­ic mol­e­cules that cause in­flam­ma­tion and tis­sue dam­age.

Anil Bhushan

Back in 2018, Man­sukhani was in­tro­duced to Anil Bhushan, a pro­fes­sor at the Uni­ver­si­ty of Cal­i­for­nia, San Fran­cis­co, who was work­ing on a way to weaponize in­vari­ant Nat­ur­al Killer T (iNKT) cells against senes­cent cells to treat type 1 di­a­betes. iNKT cells act as a sort of sur­veil­lance sys­tem, elim­i­nat­ing for­eign cells, but be­come less ac­tive with age and oth­er fac­tors.

“I fol­lowed senes­cence for a long time, but I nev­er ever thought about it in the con­text of type 1 di­a­betes. So that da­ta just kind of knocked me aside,” Man­sukhani said.

He did his own re­search, then about six weeks lat­er teamed up with Bhushan to launch De­cid­u­ous Ther­a­peu­tics. While the team is no longer go­ing af­ter di­a­betes, they pub­lished a pa­per on Mon­day in Med link­ing in vi­vo iNKT cells with clear­ing senes­cent cells.

“These cells have long been of in­ter­est to peo­ple — they just, you know, haven’t re­al­ly fig­ured out what to do with them or what they re­al­ly do,” Man­sukhani, now CEO, said. “There was some­thing in the senes­cent cell that said, OK, there’s a foot­print here to an im­mune cell that’s go­ing to talk to this senes­cent cell and clear it out. And that’s where things get ex­cit­ing.”

iNK­Ts have two main at­trib­ut­es that make them an ap­peal­ing tar­get, Man­sukhani ex­plained. First, they have the same re­cep­tor, which doesn’t ap­pear on any oth­er cell in the body, al­low­ing a high lev­el of speci­fici­ty. And they al­so op­er­ate in a nat­ur­al neg­a­tive feed­back loop, that re­turns them to dor­man­cy af­ter a pe­ri­od of ac­tiv­i­ty.

“Us­ing iNKT-tar­get­ed ther­a­py can pig­gy­back on their ex­quis­ite, built-in speci­fici­ty,” Bhushan said in a state­ment.

Us­ing the ap­proach, the sci­en­tists were able to im­prove blood glu­cose lev­els in mice with di­et-in­duced obe­si­ty, and ex­tend the lives of mice with lung fi­bro­sis. Go­ing forth, Man­sukhani said the team is go­ing to look at things like chron­ic kid­ney dis­ease and car­diac fi­bro­sis. He ex­pects to hit the clin­ic in mid-to-late 2023.

“The ra­tio­nale here was that, if this hap­pens nat­u­ral­ly in the body by the im­mune sys­tem, let’s just go back and un­der­stand that first, and then we can fig­ure out what to do with that in­for­ma­tion once we ac­tu­al­ly un­der­stand that un­der­ly­ing first prin­ci­ple,” he said.

The Fac­tors Dri­ving a Rapid Evo­lu­tion of Gene & Cell Ther­a­py and CAR-T Clin­i­cal Re­search in APAC

APAC is the fastest growing region globally for cell & gene therapy trials representing more than a third of all cell & gene studies globally, with China leading in the region. 

APAC is the leading location globally for CAR-T trials with China attracting ~60% of all CAR-T trials globally between 2015-2022. The number of CAR-T trials initiated by Western companies has rapidly increased in recent years (current CAGR of about 60%), with multiple targets being explored including CD19, CD20, CD22, BCMA, CD30, CD123, CD33, CD38, and CD138.

EMA warns of short­ages of two Boehringer heart drugs due to a spike in de­mand

The EMA is putting EU member states on alert over the shortage of two drugs that counter heart attacks due to an uptick in demand.

On Friday, the EMA sent out a warning that two Boehringer Ingelheim drugs are experiencing a shortage: Actilyse and Metalyse. The drugs are used as emergency treatments for adults experiencing acute myocardial infarction, or a heart attack, by dissolving blood clots that have formed in the blood vessels.

The End­points 11: The top pri­vate biotechs in pur­suit of new drugs. Push­ing the en­ve­lope with pow­er­ful new tech­nolo­gies

Right around the beginning of the year, we got a close-up look at what happens after a boom ripples through biotech. The crash of life sciences stocks in Q1 was heard around the world.

In the months since, we’ve seen the natural Darwinian down cycle take effect. Reverse mergers made a comeback, with more burned out shells to go public at a time IPOs and road shows are out of favor. And no doubt some of the more recent arrivals on the investing side of the business are finding greener pastures.

As­traZeneca, Mer­ck cull one Lyn­parza in­di­ca­tion in heav­i­ly pre­treat­ed ovar­i­an can­cer pa­tients

Just one day after blockbuster Lynparza got access to another indication in China, its Big Pharma owners have decided to withdraw it in certain patients after reviewing Phase III data.

The two companies that work together on Lynparza decided to recall one of the indications several weeks ago in a specific type of ovarian cancer, Lynparza’s first indication when it was first FDA-approved in 2014. Initial data showed that rates of overall survival in patients with at least three rounds of chemo before getting on the PARP inhibitor were lower than in patients with less previous chemo treatment.

Fu­ji­film con­tin­ues CD­MO ex­pan­sion, break­ing ground on $435M UK site

Fujifilm’s CDMO arm, Fujifilm Diosynth, has been on a roll this month as the company has recently broken ground on a major project in Europe and it appears to be keeping up the momentum.

Fujifilm Diosynth announced that it has kicked off an expansion project for its microbial manufacturing facility at its campus in the town of Billingham, UK, in the northeast of England.

The 20,000 square-foot, £400 million ($435 million) expansion will add clean rooms, purification suites and a packing area along with more space for the manufacturing itself.

Should SCO­TUS hear Am­gen's Repatha case? So­lic­i­tor gen­er­al says no

Back in April, Amgen said it was encouraged by the solicitor general’s anticipated review of its Supreme Court petition to rehear a Repatha patent case. They’re likely much less optimistic about the outcome now.

Solicitor General Elizabeth Prelogar wrote in a recent 27-page brief that Amgen’s arguments “lack merit and further review is not warranted.”

The case traces back to a suit filed in 2014 against Sanofi and Regeneron’s Praluent, which ended up beating Amgen’s PCSK9 blockbuster Repatha to market by a month just a year later.

Klick Health gath­ers biotech and phar­ma lu­mi­nar­ies to dis­cuss in­dus­try in­no­va­tions, in­vest­ments and fu­ture

At Klick Health’s first Ideas Exchange conference with biotech and pharma industry insiders since before the pandemic began, it was no surprise many conversations included Covid topics. Yet while vaccines and treatments were discussed, so too were the effects on drug development, federal responses, health inequities — and what to do now and next.

George Yancopoulos, chief scientist and cofounder of Regeneron, opened the conference responding to a question from Acorda CEO Ron Cohen about the spotlight on the industry during Covid and some of the “flak” biopharma has taken in the past.

FDA's out­side ex­perts vote in fa­vor of Fer­ring's fe­cal trans­plant for C. dif­fi­cile, set­ting the stage for Seres

FDA’s outside advisors voted in favor of Ferring Pharmaceuticals’ RBX2660, an experimental poop-based drug implant that the company says would be the first microbiota-based live biotherapeutic to receive an FDA green light.

That was a point repeatedly discussed during the Vaccines and Related Biological Products Advisory Committee, or VRBPAC, meeting Thursday when evaluating Ferring’s fecal microbiota transplant, or FMT, for reducing the recurrence of Clostridioides difficile infection in adults who have received antibiotics. Multiple members brought up the need for a regulated product amid a landscape of unregulated FMTs already happening in clinical care.
