FDA ad­vis­ers back No­var­tis’ game-chang­ing per­son­al­ized CAR-T for can­cer, ap­proval in sight

The FDA’s ad­vi­so­ry com­mit­tee on can­cer drugs has of­fered a group thumbs-up for No­var­tis’ trail­blaz­ing CAR-T CTL019 (ti­s­agen­le­cleu­cel), mark­ing a key mile­stone for the phar­ma gi­ant as it nears the like­ly launch of a ground­break­ing per­son­al­ized cell ther­a­py for B-cell acute lym­phoblas­tic leukemia.

These out­side ex­perts at the FDA vot­ed 10 to 0 to urge an ap­proval for this drug, of­fer­ing some key sup­port af­ter reg­u­la­tors care­ful­ly re­viewed the com­plex man­u­fac­tur­ing process as well as the safe­ty and ef­fi­ca­cy pro­files of this ther­a­py.

Key to No­var­tis’ suc­cess was the high re­mis­sion rate as well as 6-month and 12-month sur­vival da­ta for chil­dren and young adult pa­tients who were run­ning out of op­tions. The pa­tient num­bers were small, but the re­spons­es were ex­tra­or­di­nary for the pa­tients who re­spond­ed, with an 83% over­all re­mis­sion rate and 79% over­all sur­viv­abil­i­ty rate at 12 months – hit­ting the pri­ma­ry end­point.

“This is a nov­el ther­a­py, there’s an un­met med­ical need, a strong ef­fi­ca­cy and a good risk mit­i­ga­tion strat­e­gy,” not­ed com­mit­tee mem­ber James Gul­ley from the Na­tion­al Can­cer In­sti­tute.

Alan Rein from the Cen­ter for Can­cer Re­search cit­ed the drug’s “re­mark­able clin­i­cal suc­cess­es,” though he not­ed some lin­ger­ing con­cerns with the long-term risks in­volved. And oth­ers echoed those re­marks, rais­ing the prospect that CAR-T can be a game-chang­er in this field.

David Leb­wohl

David Leb­wohl, No­var­tis’ chief of the CTL019 pro­gram, told the pan­el ear­li­er in the day that these out­comes were un­like any­thing he’d seen in 20 years of prac­tice.

But this ther­a­py is al­so linked with threat­en­ing side ef­fects. While pa­tients on this en­gi­neered CAR cell ther­a­py have been re­peat­ed­ly hit by po­ten­tial­ly lethal cas­es of cy­tokine re­lease syn­drome and neu­ro­log­i­cal tox­i­c­i­ty with the threat of new ma­lig­nan­cies, ad­vis­ers were clear­ly will­ing to ac­cept the risk in or­der to achieve the po­ten­tial gains. There were no cas­es of cere­bral ede­ma, in­ves­ti­ga­tors not­ed, but oth­er CAR-Ts have been linked to such cas­es.

No­var­tis al­so not­ed the death of a pa­tient from a cere­bral he­m­or­rhage. Al­so, 9 pa­tients had to dis­con­tin­ue the tri­al af­ter CTL019 couldn’t be man­u­fac­tured for them – a key short­fall that No­var­tis will have to man­age care­ful­ly if it gets a green light for man­u­fac­tur­ing.

Sev­er­al of the com­mit­tee mem­bers, though, of­fered No­var­tis a vote of con­fi­dence on their risk mit­i­ga­tion strat­e­gy and the abil­i­ty of spe­cial­ists in the field to han­dle side ef­fects.

The last three years of de­vel­op­ment work at No­var­tis has been marked by or­ga­ni­za­tion­al re­struc­tur­ing along with the ad­vance and re­treat of ri­val ther­a­pies – all while sort­ing through a threat­en­ing list of tox­i­c­i­ty fac­tors. But No­var­tis’ team main­tained their lead, de­liv­er­ing on a promise No­var­tis CEO Joe Jimenez made to per­sist with the de­vel­op­ment of a dra­mat­ic new ap­proach to treat­ing can­cer.

Ob­servers crowd­ed in­to the FDA’s pre­sen­ta­tion room this morn­ing, rub­bing shoul­ders with CAR-T celebs like Penn’s Carl June with many, many more look­ing on on­line. But the re­view in­volves more than just one ther­a­py at one com­pa­ny. The ad­vis­ers gath­ered at a time that the FDA has com­mit­ted it­self to ac­cel­er­at­ing the de­vel­op­ment of ma­jor new ther­a­pies un­der new FDA com­mis­sion­er Scott Got­tlieb, and CTL019 will be viewed as a test case for the agency’s open­ness to new ther­a­pies that are not yet thor­ough­ly probed in ad­vanced clin­i­cal tri­als.

The vote al­so un­der­scores ODAC’s in­grained ac­cep­tance of mod­er­ate risk when it comes to treat­ing pa­tients dy­ing of can­cer.

Close on No­var­tis’ heels is a team from Kite, a CAR-T-fo­cused biotech which had hoped to be the first to the mar­ket. Kite to­day got a front row seat to the way the agency views these ther­a­pies, and it’s like­ly to take ad­van­tage of that in its own up­com­ing reg­u­la­to­ry re­view.

Be­hind them comes Juno, with a new lead drug, and a group of play­ers like Cel­lec­tis, which are in the ear­ly stages of de­vel­op­ing what they hope can be off-the-shelf ther­a­pies that should be less ex­pen­sive to make and mar­ket.

A 9/11-era Om­a­ha fa­cil­i­ty, an old Ebo­la drug, and the ubiq­ui­tous Dr. Fau­ci: In­side the first US nov­el coro­n­avirus tri­al

The first 11 coronavirus patients who arrived in Omaha last week, airlifted across the globe after two weeks quarantined on a cruise ship, showed only minor symptoms or none at all. And then one of them — or one of the couple of Americans who arrived later — got worse. He developed pneumonia, a life-threatening complication for coronavirus patients.

In a biocontainment room at the University of Nebraska Medical Center on Friday, doctors infused him with an experimental Gilead drug once developed for Ebola, called remdesivir. Or they gave him a placebo. For the first time in the US, neither he nor the doctors knew.

The first US novel coronavirus trial was underway and with it, a mad dash for an answer. Sponsored by the NIH, the study marked a critical point in the epidemic. Since the start of the outbreak, the agency had helped lead a global effort to contain the virus. Now, as it spread worldwide and the CDC issued warnings the US could see a major internal outbreak, they were looking at home.

“We don’t have too much time,” Andre Kalil, the trial’s lead investigator, told Endpoints News. “Everything’s moving really fast.”

Grow­ing ac­cep­tance of ac­cel­er­at­ed path­ways for nov­el treat­ments: but does reg­u­la­to­ry ap­proval lead to com­mer­cial suc­cess?

By Mwango Kashoki, MD, MPH, Vice President-Technical, and Richard Macaulay, Senior Director, of Parexel Regulatory & Access

In recent years, we’ve seen a significant uptake in the use of regulatory options by companies looking to accelerate the journey of life-saving drugs to market. In 2018, 73% of the novel drugs approved by the U.S. Federal Drug Administration (FDA) were designated under one or more expedited development program categories (Fast Track, Breakthrough Therapy, Priority Review, and Accelerated Approval).ᶦ

Jim Wilson's gene ther­a­py start­up Pas­sage Bio bucks mar­ket sen­ti­ments, rais­ing up­sized $216M IPO

A coronavirus fear-induced bloodbath on the Nasdaq has not stopped Passage Bio from making a public debut — and an exuberant one.

By pricing an upsized offering at $18, the top of the range, the gene therapy biotech bagged $216 million from its IPO, 72% more than it’s originally penciled in.

The proceeds likely reflected confidence in Jim Wilson, who gathered all the tools he’s built over decades of gene therapy research to assemble the startup and teamed up with Frazier and OrbiMed to hone its focus on rare, monogenic disorders of the central nervous system. Just before the IPO, Deerfield partner Bruce Goldsmith took over from OrbiMed’s Stephen Squinto as CEO.

UP­DAT­ED: A name emerges out of the Gilead M&A ru­mor mill, and it’s a can­cer biotech

After months of questions and speculation about when and if Gilead will make a major acquisition, a name has emerged.

The California-based drugmaker has approached Forty Seven Inc, a cancer biotech, with a takeover offer, Bloomberg News reports. With Forty Seven’s market cap at $2.3 billion, an acquisition would likely be Gilead’s largest since they acquired Kite Pharma for $11.9 billion in 2017.

Biogen head of R&D Al Sandrock, Sangamo CEO Sandy Macrae

UP­DAT­ED: Bio­gen makes an­oth­er bold Alzheimer’s bet, drop­ping $350M up­front to part­ner with genome-edit­ing fo­cused Sang­amo

While the fate of Biogen’s resurrected Alzheimer’s drug aducanumab remains uncertain, the Cambridge, MA-based drugmaker is joining forces with genome editing company Sangamo Therapeutics to develop therapies for neurological conditions.

Sangamo is set to receive a meaty $350 million upfront in cash and stock and is eligible to receive up to $2.37 billion in milestone payments, in addition to royalties. In return, Biogen gets the rights to two Sangamo preclinical compounds: ST-501 (for use in tauopathies including Alzheimer’s disease) and ST-502 (for synucleinopathies including Parkinson’s disease).

“The partnership represents a lower-cost way to expand its work in neurologic disease,” Credit Suisse’s Evan Seigerman said in a note, referring to Biogen.

UP­DAT­ED: Bio­haven scores CGRP OK for acute mi­graine — can the com­mer­cial team catch up with Al­ler­gan on its de­but?

Seven years after spinning out of Yale, Biohaven has entered the ranks of commercial-stage biotechs.

The FDA handed down an OK for its CGRP drug, rimegepant, as an acute treatment. Dubbed Nurtec, the orally dissolving pill will join Allergan’s (soon to be AbbVie’s) Ubrelvy and Lilly’s Reyvow on the market amid a new wave of migraine therapies reshaping the disease space.

In a pivotal Phase III trial, Nurtec hit the co-primary endpoints on pain freedom and freedom from most bothersome symptoms at two hours post dose, proving superior to placebo.
