Can prog­en­i­tor cells go fur­ther than gene ther­a­py in reti­nal dis­or­ders? A biotech's an­swer shines in PhI­Ib

By the time the FDA ap­proved Lux­tur­na — the pi­o­neer­ing gene ther­a­py for an in­her­it­ed reti­nal dis­ease — Hen­ry Klassen had been re­search­ing and treat­ing the group of dis­eases known as re­tini­tis pig­men­tosa for more than 20 years.

Spark Ther­a­peu­tics’ suc­cess there had not just in­spired a $4.3 bil­lion takeover by Roche, it had al­so em­bold­ened oth­er biotechs pur­su­ing a ther­a­py that would de­liv­er one of the genes tied to dif­fer­ent vari­a­tions of the dis­or­der. Night­star Ther­a­peu­tics sub­se­quent­ly scored its own buy­out with Bio­gen, and MeiraGTx re­cent­ly post­ed ear­ly but “ex­cit­ing da­ta” on its J&J-part­nered pro­gram.

But Klassen went a dif­fer­ent way.

Catch­ing on the stem cell craze right at the turn of the mil­len­ni­um, he took in­spi­ra­tion from sci­en­tists who trans­plant­ed neur­al prog­en­i­tor cells in­to the reti­na and de­vel­oped a method to grow reti­nal prog­en­i­tor cells in­stead as a ther­a­py. Start­ing out as the di­rec­tor of stem cell re­search at the Chil­dren’s Hos­pi­tal of Or­ange Coun­ty, he con­tin­ued the work at the Uni­ver­si­ty of Cal­i­for­nia, Irvine, even­tu­al­ly spin­ning out a biotech dubbed jCyte in 2012.

Over the week­end jCyte re­port­ed pos­i­tive Phase IIb re­sults from what they call one of the largest stud­ies ever con­duct­ed in RP, sug­gest­ing that pa­tients on the treat­ment saw im­proved func­tion­al vi­sion com­pared to the place­bo group.

“The cred­it to the gene ther­a­pies is that they’re ac­tive­ly try­ing to fix the gene un­der­ly­ing the prob­lem. That’s very com­mend­able, and we’re not do­ing that,” Klassen told End­points News. “But our treat­ment as it stands should have im­pact across a va­ri­ety of dif­fer­ent geno­types.”

The study en­rolled a to­tal of 84 pa­tients, of whom 74 were in­clud­ed for the fi­nal analy­sis. For each pa­tient on the pri­ma­ry end­point of best cor­rect­ed vi­su­al acu­ity (mea­sured with glass­es on), the mean change from base­line to month 12 for the sham, low dose and high dose arms were +2.81, +2.96, and +7.43 let­ters, re­spec­tive­ly.

In a post hoc analy­sis for a tar­get sub­group, the dif­fer­ence was even more promi­nent: +1.85, -0.15, and +16.27 let­ters, re­spec­tive­ly.

There was one se­ri­ous ad­verse event in the low dose arm, but jCyte said the grade 3 oc­u­lar hy­per­ten­sion re­solved with treat­ment and oth­er side ef­fects were gen­er­al­ly mi­nor.

CEO Paul Bres­ge not­ed that the tar­get sub­group analy­sis was in­tend­ed to ham­mer out the cri­te­ria they might use to re­cruit pa­tients in­to Phase III — which would like­ly have a sim­i­lar de­sign and use the same pri­ma­ry end­point of BC­VA, the “gold stan­dard in the con­text of FDA.” The late-stage tri­al is slat­ed for 2021.

“We did en­roll a very wide pa­tient pop­u­la­tion in­to our Phase IIb, in­clud­ing pa­tients that had vi­sion any­where from 20/80 to 20/800, just to learn which pa­tients would po­ten­tial­ly be the best re­spon­ders,” he said.

The tar­get sub­group is char­ac­ter­ized by hav­ing re­li­able fix­a­tion on the study eye, and a study eye that does not have sig­nif­i­cant­ly worse BC­VA (≤15 let­ters) than the fel­low eye.

He added that in­ves­ti­ga­tors al­so ob­served en­cour­ag­ing re­sults with the sec­ondary end­points such as low light mo­bil­i­ty, con­trast sen­si­tiv­i­ty ki­net­ic vi­su­al fields and a vi­sion func­tion ques­tion­naire, al­though the da­ta weren’t dis­closed.

“Typ­i­cal­ly peo­ple think about the dis­ease as a nar­row­ing of this pe­riph­er­al vi­sion in a very nice gran­u­lar way, but that’s ac­tu­al­ly not what hap­pens,” he said about the vi­su­al fields find­ing. “What hap­pens in the dis­ease is that pa­tients lose like is­lands of vi­sion. So what we’re do­ing in our tests is ac­tu­al­ly mea­sur­ing […] is­lands that the pa­tients have at base­line, and then what we’re see­ing af­ter treat­ment is that the is­lands are ex­pand­ing. It’s sim­i­lar to the way that one would track, let’s say a tu­mor, in on­col­o­gy of course we’re look­ing for the op­po­site ef­fect. We’re look­ing for the is­lands of vi­sion to ex­pand.”

The ther­a­py works pri­mar­i­ly by pre­serv­ing pho­tore­cep­tors, Klassen posits, not by gen­er­at­ing new ones. But what he thinks is hap­pen­ing is that pho­tore­cep­tors are re­gen­er­at­ing the out­er seg­ment — if pho­tore­cep­tors are ra­dios, these would be the an­ten­na — there­by re­gain­ing some func­tion.

That could po­si­tion it as a treat­ment for a dif­fer­ent stage of the dis­ease than Spark’s or Night­star’s. Klassen, who’s al­so re­search­ing reti­nal re­con­struc­tion us­ing stem cells, is hap­py to not view it through the com­pet­i­tive lens.

“If you look in­to the fu­ture, one could imag­ine that gene ther­a­pies will be most ef­fec­tive very ear­ly in the course of a dis­ease be­fore pho­tore­cep­tors are lost,” he said. “Then as pho­tore­cep­tors be­gin to be lost any­way, if that hap­pens, then a ther­a­py like ours would be­come ex­treme­ly valu­able. And if ours starts to lose pow­er late in the course of a dis­ease, maybe cell trans­plan­ta­tion un­der the reti­na could have a role.”

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.

No­var­tis de­tails plans to axe 8,000 staffers as Narasimhan be­gins sec­ond phase of a glob­al re­org

We now know the number of jobs coming under the axe at Novartis, and it isn’t small.

The pharma giant is confirming a report from Swiss newspaper Tages-Anzeiger that it is chopping 8,000 jobs out of its 108,000 global staffers. A large segment will hit right at company headquarters in Basel, as CEO Vas Narasimhan axes some 1,400 of a little more than 11,000  jobs in Switzerland.

The first phase of the work is almost done, the company says in a statement to Endpoints News. Now it’s on to phase two. In the statement, Novartis says:

Phar­ma group bets up to $1B-plus on the PhI­II res­ur­rec­tion of a once dead-and-buried LDL drug

Close to 5 years after then-Amgen R&D chief Sean Harper tamped the last spade of dirt on the last broadly focused CETP cholesterol drug — burying their $300 million upfront and the few remaining hopes for the class with it — the therapy has been fully resurrected. And today, the NewAmsterdam Pharma crew that did the Lazarus treatment on obicetrapib is taking another big step on the comeback trail with a €1 billion-plus regional licensing deal, complete with close to $150 million in upfront cash.

How pre­pared is bio­phar­ma for the cy­ber dooms­day?

One of the largest cyberattacks in history happened on a Friday, Eric Perakslis distinctly remembers.

Perakslis, who was head of Takeda’s R&D Data Sciences Institute and visiting faculty at Harvard Medical School at the time, had spent that morning completing a review on cybersecurity for the British Medical Journal. Moments after he turned it in, he heard back from the editor: “Have you heard what’s going on right now?”

Some phar­ma com­pa­nies promise to cov­er abor­tion-re­lat­ed trav­el costs — while oth­ers won't go that far yet

As the US Department of Health and Human Services promises to support the millions of women who would now need to cross state lines to receive a legal abortion, a handful of pharma companies have said they will pick up employees’ travel expenses.

GSK, Sanofi, Johnson & Johnson, BeiGene, Alnylam and Gilead have all committed to covering abortion-related travel expenses just four days after the Supreme Court overturned Roe v. Wade and revoked women’s constitutional right to an abortion.

Aurobindo Pharma co-founders P. V. Ram Prasad Reddy (L) and K. Nityananda Reddy

Au­robindo Phar­ma re­ceives warn­ing let­ter from In­di­a's SEC fol­low­ing more FDA ques­tion marks

Indian-based generics manufacturer Aurobindo Pharma has been in the crosshairs of the FDA for several years now, but the company is also attracting attention from regulators within the subcontinent.

According to the Indian business news site Business Standard, a warning letter was sent to the company from the Securities Exchange Board of India, or SEBI.

The letter is related to disclosures made by the company on an ongoing FDA audit of the company’s Unit-1 API facility in Hyderabad, India as well as observations made by the US regulator between 2019 and 2022.

Basilea toss­es an on­col­o­gy drug back to Mer­ck, dou­bling down on an­tibi­otics in re­vamp

Swiss biotech Basilea Pharmaceutica has shed one of its last pipeline ties with oncology as it makes a move to concentrate on antibiotics in a race to profitability next year. And they’ve followed up on that with news of a Phase III success they believe can help expand prospects for a key franchise player.

The company put out word on Monday that the execs are handing rights to the FGFR inhibitor derazantinib back to Merck by the end of this year as it shuts down clinical work on the tumor checkpoint controller lisavanbulin. They’re still working on partnering that out along with their TTK/PLK1-inhibitor BAL0891 and preclinical oncology assets.

Charles Riv­er Lab­o­ra­to­ries to start cell and gene ther­a­py man­u­fac­tur­ing at UK site in Sep­tem­ber

While Massachusetts-based Charles River Laboratories has been on an acquisition spree, they are not against planting their flag. The latest move by the company sees them crossing the pond to establish a manufacturing site in the UK.

The company on Tuesday opened its cell and gene therapy manufacturing center at Bruntwood SciTech’s Alderley Park in Cheshire, United Kingdom. The expansion follows Charles River’s acquisition of Cognate BioServices and Cobra Biologics in 2021 for $875 million. Cognate is a plasmid DNA, viral vector and cell therapy CDMO.
