Over a year af­ter re­jec­tion, Im­munomedics emerges with po­ten­tial block­buster ap­proval

A tur­bu­lent 16 months for Im­munomedics has end­ed in a po­ten­tial block­buster ap­proval, as the FDA grant­ed an ac­cel­er­at­ed OK for their drug to treat an ag­gres­sive form of breast can­cer.

The drug, brand­ed as Trodelvy, is ap­proved for metasta­t­ic triple neg­a­tive breast can­cer — breast can­cers that lack the onco­genes that tar­get­ed ther­a­pies go af­ter and that have helped make the dis­ease treat­able for some pa­tients. The drug, which had break­through sta­tus and pri­or­i­ty re­view, showed a 33% re­sponse and me­di­an du­ra­tion of re­sponse of 7.7 months in 108 pa­tients en­rolled in their Phase II tri­al. Peak sales es­ti­mates can range as high as around $3 bil­lion.

The ap­proval comes over a month in ad­vance of the com­pa­ny’s June 2 PDU­FA date, con­tin­u­ing the agency’s trend of quick­ly ap­prov­ing can­cer drugs they deem ef­fec­tive.

Be­hzad Ag­haz­adeh

A lit­tle over a year ago, the FDA sur­prised both the com­pa­ny and in­vestors by re­ject­ing the drug. Al­though Im­munomedics $IM­MU said the con­cern had on­ly been with qual­i­ty con­trols over the fa­cil­i­ty where the drug is pro­duced, the re­jec­tion of the biotech’s main as­set shaved $1 bil­lion off the com­pa­ny’s mar­ket cap. Not long af­ter, an FDA in­spec­tion doc­u­ment raised con­cerns of a da­ta breach at one of the com­pa­ny’s fa­cil­i­ties. The CEO and CSO both lat­er ex­it­ed, and chair­man Be­hzad Ag­haz­adeh stepped in to run the com­pa­ny.

The drug, known chem­i­cal­ly as sac­i­tuzum­ab govite­can, is the com­pa­ny’s first ap­proval in their 37-year his­to­ry. An an­ti­body-drug con­ju­gate, it con­sists of a tu­mor-tar­get­ing an­ti­body at­tached to a cell-killing small mol­e­cule. The tu­mor en­gulfs the con­ju­gate and the mol­e­cule kills the can­cer cells. The idea first emerged in the ear­ly 2000s be­fore pe­ter­ing out, but has gained trac­tion again in re­cent years, most no­tably with the re­cent ap­provals of Seat­tle Ge­net­ics’ Ad­cetris and Pad­cev.

Seat­tle Ge­net­ics near­ly ac­quired the Im­munomedics drug in 2016. They agreed to an up-to $2 bil­lion deal worth $300 mil­lion be­fore ven­Bio, which owned a 9.9% stake in the com­pa­ny, led a cam­paign against the deal, with then-man­ag­ing parter Ag­haz­adeh ac­cus­ing the com­pa­ny’s lead­er­ship of try­ing to en­rich them­selves. The hus­band-and-wife team who then ran the com­pa­ny as CSO and CEO re­signed, and Ag­haz­adeh lat­er or­ga­nized a $250 mil­lion roy­al­ty deal to fund the com­pa­ny’s work.

Harout Se­mer­jian

An ac­cel­er­at­ed ap­proval is con­di­tion­al on the com­pa­ny con­duct­ing a fol­low-up study. That tri­al, though, has al­ready been stopped, with an in­de­pen­dent re­view board telling Im­munomedics ear­ly this month their drug had al­ready shown enough com­pelling ef­fi­ca­cy. On the same day of the tri­al news, the com­pa­ny al­so an­nounced that No­var­tis On­col­o­gy vet Harout Se­mer­jian had been named as the new CEO.

Com­mit­tee chair and Fred Hutch re­searcher Julie Gralow called the re­sults of the Phase III tri­al “re­mark­able.” The com­ment led Cowen’s Phil Nadeau to write, “There is lit­tle ques­tion that sac­i­tuzum­ab will soon be­come stan­dard of care in the treat­ment of re­lapsed and re­frac­to­ry mTNBC.”

Up­dat­ed: FDA re­mains silent on or­phan drug ex­clu­siv­i­ty af­ter last year's court loss

Since losing a controversial court case over orphan drug exclusivity last year, the FDA’s Office of Orphan Products Development has remained entirely silent on orphan exclusivity for any product approved since last November, leaving many sponsors in limbo on what to expect.

That silence means that for more than 70 orphan-designated indications for more than 60 products, OOPD has issued no public determination on the seven-year orphan exclusivity in the Orange Book, and no new listings of orphan exclusivity appear in OOPD’s searchable database, as highlighted recently by George O’Brien, a partner in Mayer Brown’s Washington, DC office.

As mon­ey pours in­to dig­i­tal ther­a­peu­tics, in­sur­ance cov­er­age crawls



Talk therapy didn’t help Lily with attention deficit hyperactivity disorder, or ADHD. But a video game did.

As the 10-year-old zooms through icy waters and targets flying creatures on the snow-capped planet Frigidus, she builds attention skills, thanks to Akili Interactive Labs’ video game EndeavorRx. She’s now less anxious and scattered, allowing her to stay on a low dose of ADHD medication, according to her mom Violet Vu.

Vi­a­tris with­draws ac­cel­er­at­ed ap­proval for top­i­cal an­timi­cro­bial 24 years lat­er

After 24 years without confirming clinical benefit, the FDA announced Tuesday morning that Viatris (formed via Mylan and Pfizer’s Upjohn) has decided to withdraw a topical antimicrobial agent, Sulfamylon (mafenide acetate), after the company said conducting a confirmatory study was not feasible.

Sulfamylon first won FDA’s accelerated nod in 1998 as a topical burn treatment, with the FDA noting that last December, Mylan told the agency that it wasn’t running the trial.

Eli Lil­ly’s Alzheimer’s drug clears more amy­loid ear­ly than Aduhelm in first-ever head-to-head. Will it mat­ter?

Ahead of the FDA’s decision on Eli Lilly’s Alzheimer’s drug donanemab in February, the Big Pharma is dropping a first cut of data from one of the more interesting trials — but less important in a regulatory sense — at an Alzheimer’s conference in San Francisco.

In the unblinded 148-person study, Eli Lilly pitted its drug against Aduhelm, Biogen’s drug that won FDA approval but lost Medicare coverage outside of clinical trials. Notably, the study didn’t look at clinical outcomes, but rather the clearance of amyloid, a protein whose buildup is associated with Alzheimer’s disease, in the brain.

Lynn Baxter, Viiv Healthcare's head of North America

Vi­iV dri­ves new cor­po­rate coali­tion in­clud­ing Uber, Tin­der and Wal­mart, aimed at end­ing HIV

ViiV Healthcare is pulling together an eclectic coalition of consumer businesses in a new White House-endorsed effort to end HIV by the end of the decade.

The new US Business Action to End HIV includes pharma and health companies — Gilead Sciences, CVS Health and Walgreens — but extends to a wide range of consumer companies that includes Tinder, Uber and Walmart.

ViiV is the catalyst for the group, plunking down more than half a million dollars in seed money and taking on ringmaster duties for launch today on World AIDS Day, but co-creator Health Action Alliance will organize joint activities going forward. ViiV and the alliance want and expect more companies to not only join the effort, but also pitch in funding.

As com­peti­tors near FDA goal­post, Roche spells out its re­peat Alzheimer's set­back

Before Roche can turn all eyes on a new version of its more-than-once-failed Alzheimer’s drug gantenerumab, the Big Pharma had to flesh out data on the November topline failure at an annual conference buzzier than in years past thanks to hotly watched rivals in the field: Eisai and Biogen’s lecanemab, and Eli Lilly’s donanemab.

There was less than a 10% difference between Roche’s drug and placebo at slowing cognitive decline across two Phase III trials, which combined enrolled nearly 2,000 Alzheimer’s patients. In its presentation at the conference Wednesday, Roche said it saw less sweeping away of toxic proteins than it had anticipated. For years, researchers and investors have put their resources behind the idea that more amyloid removal would equate to reduced cognitive decline.

Ei­sai’s ex­pand­ed Alzheimer’s da­ta leave open ques­tions about safe­ty and clin­i­cal ben­e­fit

Researchers still have key questions about Eisai’s investigational Alzheimer’s drug lecanemab following the publication of more Phase III data in the New England Journal of Medicine Tuesday night.

In the paper, which was released in conjunction with presentations at an Alzheimer’s conference, trial investigators write that a definition of clinical meaningfulness “has not been established.” And the relative lack of new information, following topline data unveiled in September, left experts asking for more — setting up a potential showdown to precisely define how big a difference the drug makes in patients’ lives.

Twit­ter dis­ar­ray con­tin­ues as phar­ma ad­ver­tis­ers ex­tend paus­es and look around for op­tions, but keep tweet­ing

Pharma advertisers on Twitter are done — at least for now. Ad spending among the previous top spenders flattened even further last week, according to the latest data from ad tracker Pathmatics, amid ongoing turmoil after billionaire boss Elon Musk’s takeover now one month ago.

Among 18 top advertisers tracked for Endpoints News, only two are spending: GSK and Bayer. GSK spending for the full week through Sunday was minimal at just under $1,900. Meanwhile, German drugmaker Bayer remains the industry outlier upping its spending to $499,000 last week from $480,000 the previous week. Bayer’s spending also marks a big increase from a month ago and before the Musk takeover, when it spent $16,000 per week.

Ar­genx pur­chas­es $100M+ FDA pri­or­i­ty re­view vouch­er from blue­bird bio

Argenx’s Vyvgart is due for a speedy review at the FDA, thanks to a $102 million priority review voucher (PRV).

The Netherland-based biotech picked up the PRV from bluebird bio, the companies announced on Wednesday. PRVs shorten a drug’s FDA review period from 10 months to 6 months, though they often sell on the open market for around $100 million each.

Argenx plans on using the express ticket on efgartigimod, its neonatal Fc receptor (FcRn) blocker marketed as Vyvgart for adults with generalized myasthenia gravis (gMG). While Vyvgart won its first approval last December for the chronic neuromuscular disease — which is characterized by difficulties with facial expression, speech, swallowing and breathing — CEO Tim Van Hauwermeiren said in a news release that he plans to “be active in fifteen disease targets by 2025.”
