FDA staff large­ly un­fazed by CV sig­nal in Am­gen os­teo­poro­sis drug tri­als

FDA staff braved the snow and the fed­er­al shut­down to post their re­view of Am­gen’s once-re­ject­ed os­teo­poro­sis drug on Mon­day, un­der­scor­ing that the ef­fi­ca­cy of the drug in post­menopausal women had been es­tab­lished, and sug­gest­ing that the CV sig­nal ob­served in two tri­als may not be a sig­nif­i­cant wor­ry.

The re­view comes days af­ter Am­gen and part­ner UCB se­cured Japan­ese ap­proval for the drug, ro­mosozum­ab, and pre­cedes a meet­ing of in­de­pen­dent ex­perts on Wednes­day who will make their rec­om­men­da­tion on the ap­prov­abil­i­ty of the drug in the Unit­ed States. Ro­mosozum­ab — which is to be sold un­der the brand name Eveni­ty — func­tions pre­dom­i­nant­ly as a bone an­a­bol­ic agent that stim­u­lates bone growth.

The mon­o­clon­al an­ti­body was test­ed in three late-stage stud­ies: the 7,180-pa­tient FRAME study in post­menopausal women with os­teo­poro­sis, which test­ed the drug against a place­bo; the 4,093-pa­tient ARCH study in post­menopausal women in os­teo­poro­sis, which test­ed the drug against an os­teo­poro­sis drug orig­i­nal­ly made by Mer­ck called al­en­dronate; and the 245-pa­tient BRIDGE study in men with os­teo­poro­sis, which test­ed the drug against a place­bo.

All three piv­otal stud­ies showed the drug was ef­fec­tive, but the ARCH and BRIDGE tri­al demon­strat­ed a sig­nal of car­dio­vas­cu­lar-re­lat­ed se­ri­ous ad­verse events, which led to the FDA is­su­ing a com­plete re­sponse let­ter to the com­pa­nies, af­ter they had ap­plied for ap­proval in post­menopausal women with os­teo­poro­sis. Tak­ing in­to ac­count the CV sig­nal and feed­back from the FDA about the pauci­ty of an­a­bol­ic agents, the duo re-sub­mit­ted an ap­pli­ca­tion to mar­ket drug last year, but for a nar­row­er pa­tient pop­u­la­tion: post­menopausal women with os­teo­poro­sis who car­ry a high risk of frac­ture. They al­so pro­posed a boxed warn­ing as well as a pre­cau­tion for car­dio­vas­cu­lar risk on the drug’s la­bel, if ap­proved. Mean­while, the drug is un­der re­view in Eu­rope.

Glob­al­ly, 1 in 3 women over age 50 will ex­pe­ri­ence os­teo­porot­ic frac­tures, ac­cord­ing to the In­ter­na­tion­al Os­teo­poro­sis Foun­da­tion.

In its re­view, FDA staff agreed that the ef­fec­tive­ness of ro­mosozum­ab for the treat­ment of post­menopausal os­teo­poro­sis had been es­tab­lished, but ques­tioned whether the CV sig­nal seen in ARCH and BRIDGE were gen­er­al­iz­able to the US pop­u­la­tion, giv­en that en­rolled pa­tients from the US on­ly ac­count­ed for 1.8% of the ARCH study, and 1.4% of the BRIDGE study. In their sug­gest­ed ques­tions for in­de­pen­dent pan­el, the agency’s re­view­ers did not stress the CV is­sue.

“The docs read most­ly be­nign and dis­cus­sion/vot­ing ques­tions are not as crit­i­cal on CV risk, sup­port­ing a fa­vor­able pan­el vote on Wed (1/16) and an even­tu­al ap­proval lat­er in H1:19,” Jef­feries an­a­lysts wrote in a note, adding that Lil­ly’s os­teo­poro­sis drug For­teo car­ries a black box warn­ing high­light­ing the risk of can­cer and still rakes in about $2 bil­lion.

The drug “rep­re­sents a mod­est $500 mil­lion world­wide up­side op­por­tu­ni­ty not wide­ly ac­count­ed by con­sen­sus, and the drug has shown strong ef­fi­ca­cy (beat­ing Fos­amax by 48-50%) along with an ac­cept­able safe­ty pro­file. The pri­or safe­ty sig­nal seen in the small­er of two key Phase III stud­ies (ARCH vs FRAME) seems more spu­ri­ous than con­cern­ing to us,” they not­ed.

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.

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.

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.

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.”
