And then there were 4: Juno adds an­oth­er vic­tim in CAR-T death tal­ly

Juno’s CAR-T drugs didn’t just kill three peo­ple in clin­i­cal tri­als. They ac­tu­al­ly killed 4, as the com­pa­ny notes in its “re­vised” re­marks from last week’s tran­script of a call with com­pa­ny an­a­lysts. And the fol­lowup rais­es the mys­tery of yet an­oth­er case of cere­bral ede­ma trig­gered by se­vere neu­ro­tox­i­c­i­ty, which may or may not have been re­port­ed by Juno.

Here’s the state­ment, post­ed with the tran­script in a fil­ing with the SEC:

Note to Re­vised Re­marks: (Chief Med­ical Of­fi­cer Dr. Mark) Gilbert mis­tak­en­ly said “three” cas­es out of 129 rather than “four” cas­es. The fourth case was a pa­tient treat­ed in the JCAR014 tri­al, which case oc­curred in a young adult pa­tient with r/r ALL who re­ceived flu/cy pre­con­di­tion­ing and a high­er JCAR014 cell dose than is now used on that tri­al. This death was in­clud­ed in the da­ta pre­sent­ed in an oral pre­sen­ta­tion at the Amer­i­can So­ci­ety of Hema­tol­ogy meet­ing in De­cem­ber 2015 and in­clud­ed in Juno’s An­nu­al Re­port on Form 10-K for the fis­cal year end­ed De­cem­ber 31, 2015.

Note to Re­vised Re­marks: As not­ed ear­li­er in the ques­tion and an­swer ses­sion, the FDA al­so re­port­ed an in­stance of cere­bral ede­ma in its data­base out­side of the JCAR015 tri­al. Juno does not know whether that in­stance is the same case of cere­bral ede­ma as Juno is aware of from the JCAR014 tri­al, or if it oc­curred on a tri­al for a non-Juno prod­uct can­di­date.

Juno trig­gered a rout among its in­vestors last week when it stunned the mar­ket with news that its lead CAR-T drug, JCAR015, had killed three peo­ple in clin­i­cal stud­ies, trig­ger­ing a clin­i­cal hold of its piv­otal study by the FDA. The com­pa­ny im­me­di­ate­ly blamed the re­cent ad­di­tion of the chemo drug flu­dara­bine to pre­con­di­tion pa­tients for the cell ther­a­py and of­fered to drop the drug. In one of the fastest re­spons­es by the FDA in the face of mul­ti­ple pa­tient deaths, the agency agreed and lift­ed the hold ear­li­er this week.

The per­son­al­ized brand of CAR-Ts that Juno, Kite, and No­var­tis have been de­vel­op­ing ex­tract im­mune cells from pa­tients, re-en­gi­neer them with a chimeric anti­gen re­cep­tor and then in­ject them back in­to pa­tients, equipped to swarm can­cer cells. These new treat­ments are al­so known to trig­ger cy­tokine re­lease syn­drome, which forced a tem­po­rary pause in the ex­per­i­men­tal work a cou­ple of years ago. But Juno be­lieves that the way that flu­dara­bine was used re­cent­ly caused the neu­ro­tox­i­c­i­ty that trig­gered cas­es of cere­bral ede­ma tracked by in­ves­ti­ga­tors.

Not every­one was as quick as the FDA to buy in­to that the­o­ry, though, as sev­er­al in­ves­ti­ga­tors note that flu­dara­bine has been used reg­u­lar­ly with­out ev­i­dence of cere­bral ede­mas. In ad­di­tion, ri­val Kite Ther­a­peu­tics has used a low dose of flu­dara­bine in its work and has no plans to change as it pur­sues its own piv­otal work.

The FDA, though, is not ex­plain­ing any­thing as of now, de­clin­ing to an­swer some spe­cif­ic ques­tions of mine.

“Cel­lu­lar ther­a­pies, in­clud­ing Chimeric Anti­gen Re­cep­tor (CAR) T-Cell ther­a­pies, hold great promise in the treat­ment of se­ri­ous and life-threat­en­ing dis­eases,” the agency said in a state­ment to End­points. “We there­fore do every­thing pos­si­ble to as­sist spon­sors in ad­vanc­ing clin­i­cal de­vel­op­ment pro­grams in an ef­fort to bring promis­ing ther­a­pies to pa­tients. The FDA rec­og­nizes that in­ves­ti­ga­tion­al prod­ucts in­tend­ed to treat se­ri­ous dis­eases al­so have the po­ten­tial to pose risks to pa­tients. To this end, the FDA con­stant­ly looks at the risk-ben­e­fit pro­file of ex­per­i­men­tal ther­a­pies and when we have con­cerns about the risks, we may place the clin­i­cal tri­als on hold.”

UP­DAT­ED: Bio­gen spot­lights a pair of painful pipeline set­backs as ad­u­canum­ab show­down looms at the FDA

Biogen has flagged a pair of setbacks in the pipeline, spotlighting the final failure for a one-time top MS prospect while scrapping a gene therapy for SMA after the IND was put on hold due to toxicity.

Both failures will raise the stakes even higher on aducanumab, the Alzheimer’s drug that Biogen is betting the ranch on, determined to pursue an FDA OK despite significant skepticism they can make it with mixed results and a reliance on post hoc data mining. And the failures are being reported as Biogen was forced to cut its profit forecast for 2020 as a generic rival started to erode their big franchise drug.

As FDA sets the stage for the first Covid-19 vac­cine EUAs, some big play­ers are ask­ing for a tweak of the guide­lines

Setting the stage for an extraordinary one-day meeting of the Vaccines and Related Biological Products Advisory Committee this Thursday, the FDA has cleared 2 experts of financial conflicts to help beef up the committee. And regulators went on to specify the safety, efficacy and CMC input they’re looking for on EUAs, before they move on to the full BLA approval process.

All of this has already been spelled out to the developers. But the devil is in the details, and it’s clear from the first round of posted responses that some of the top players — including J&J and Pfizer — would like some adjustments and added feedback. And on Thursday, the experts can offer their own thoughts on shaping the first OKs.

A new chap­ter in the de­cen­tral­ized clin­i­cal tri­al ap­proach

Despite the promised decentralized trial revolution, we haven’t yet moved the needle in a significant way, although we are seeing far bolder commitments to this as we continue to experience the pandemic restrictions for some time to come. The vision of grandeur is one thing, but operationalizing and execution are another and recognising that change, particularly mid-flight on studies, is worthy of thorough evaluation and consideration in order to achieve success. Here we will discuss one of the critical building blocks of a Decentralized and Remote Trial strategy: TeleConsent; more than paper under glass, it is a paradigm change and key digital enabler.

Years af­ter a ma­jor tri­al set­back, No­var­tis switch­es gears with SMA drug. This time they're try­ing it for Hunt­ing­ton's

Four years after a Phase I/II setback in spinal muscular atrophy (SMA), Novartis is hoping its drug branaplam will find more success in a new neurological indication: Huntington’s disease.

The decision was announced a year after the head of research, Jay Bradner, said he did not see a “big opportunity” in SMA, according to Reuters. Novartis says it has preclinical data showing that branaplam reduces levels of mutant huntingtin protein, and SMA data showing patients on the drug had reductions in huntingtin mRNA. The FDA gave branaplam their orphan drug designation, and Novartis plans to move forth with a Phase IIb trial next year.

UP­DAT­ED: CRISPR Ther­a­peu­tics gets a snap­shot of off-the-shelf CAR-T suc­cess in B-cell ma­lig­nan­cies — marred by the death of a pa­tient

Just days after scientific founder Emmanuelle Charpentier shared the Nobel prize for her work on CRISPR/Cas9, CRISPR Therapeutics $CRSP is showing off a snapshot of success in their early-stage study for an off-the-shelf CAR-T approach to CD19+ B cell malignancies — a snapshot marred by the death of a patient who had been given a high dose of the treatment.

Using their gene editing tech, researchers for CRISPR engineered cells from healthy donors into an attack vehicle aimed at cancer, something that has been achieved with great success using patients’ own cells — the autologous approach. But autologous CAR-T is hampered by the more complex vein-to-vein requirement that delays treatment, and now CRISPR Therapeutics along with other players like Allogene are determined to replace the pioneers with CAR-T 2.0.

Glax­o­SmithK­line's vac­cines group aims for a first as it kicks off PhI­II RSV stud­ies

One of GlaxoSmithKline’s big projects at its global vaccine R&D center in Rockville, MD is set to enter Phase III after passing early-stage tests with flying colors.

Eyeing the wide-open respiratory syncytial virus (RSV) space, GSK is pushing two different vaccine candidates: GSK3888550A is designed to confer protection to infants via maternal immunization, while GSK3844766A is meant for the elderly.

Pur­due Phar­ma signs guilty plea, preps $8B+ set­tle­ment on Oxy con­tro­ver­sy — re­port; Flag­ship brings in a comms chief

Purdue Pharma may soon be signing off on a guilty plea and an $8 million-plus settlement to wrap up its controversial role distributing OxyContin.

The AP has the breaking story this morning.

Purdue filed for bankruptcy last year, along with Insys and followed by Mallinckrodt, as it navigated its way through a blizzard of litigation surrounding Oxy, which triggered an epidemic of abuse around the country.

RBC's Bri­an Abra­hams holds a mock ad­comm on Bio­gen's iffy ad­u­canum­ab da­ta — and most of these ex­perts don't see a path to an ap­proval

As catalysts go, few loom larger than the aducanumab adcomm slated for Nov. 6.

With its big franchise under assault, Biogen is betting the ranch that its mixed late-stage Alzheimer’s data can squeak past the experts and regulators and get onto the market. And the topic — after a decade of Alzheimer’s R&D disasters in what still represents the El Dorado of drug markets — remains in the center ring of discussions around late-stage pipeline prospects.

Lit­tle Zosano takes an­oth­er beat­ing as the FDA slaps down their ap­pli­ca­tion for a mi­graine patch

Zosano $ZSAN has officially come up short in its bid to develop a migraine patch.

The FDA rejected the company’s application to repurpose the triptan zolmitriptan in a new delivery system as Qtrypta, Zosano said Wednesday morning, issuing a CRL for the microneedle patch. Regulators cited inconsistent exposure levels across multiple clinical trials as the main reason for the thumbs down.

Investors did not take too kindly to the news, with Zosano shares plunking down around 25%. The company is requesting a Type A meeting to “provide clarity on the next steps for the program,” CEO Steven Lo said in a statement.
