Mak­er of world's most ex­pen­sive pre­scrip­tion drug flash­es PhI­II da­ta for a po­ten­tial fourth prod­uct

Three years be­fore they be­came own­ers of the most ex­pen­sive drug in the coun­try, Am­ryt be­gan its cor­po­rate life around a sin­gle ther­a­py picked up from a small Ger­man drug­mak­er called Birken: Episal­van, an EMA-ap­proved drug for par­tial thick­ness wounds. They hoped to de­vel­op it as an or­phan drug for a con­di­tion called epi­der­mol­y­sis bul­losa, where a pa­tient’s skin be­comes as frag­ile as but­ter­fly wings. They put it al­most im­me­di­ate­ly in­to a Phase III study.

To­day, Am­ryt an­nounced, the lead drug cleared the tri­al. On­ly a por­tion of topline re­sults was re­leased, but the Irish drug­mak­er said that across 223 pa­tients, those who re­ceived the drug were more like­ly to see their wounds close with­in 45 days than those on place­bo. The com­pa­ny didn’t say how much more like­ly, but not­ed that the P val­ue was 0.013. Am­ryt said it was the first pos­i­tive Phase III re­sult for any drug in epi­der­mol­y­sis bul­losa, and CEO Joe Wi­ley called it “an­oth­er sig­nif­i­cant mile­stone” for the com­pa­ny.

The drug, though, missed on all key sec­ondary end­points — which most no­tably in­clud­ed how quick­ly the first wound healed af­ter re­ceiv­ing treat­ment or place­bo.  The com­pa­ny added that “a num­ber of favourable dif­fer­ences were ob­served” and more da­ta would be com­ing out soon.

Am­ryt has al­ready brand­ed the epi­der­mol­y­sis bul­losa ver­sion of the drug as Fil­su­vez. If ap­proved, it would be the com­pa­ny’s fourth prod­uct, af­ter Episal­van and two drugs they picked up last year from the bank­rupt or­phan drug­mak­er Aege­ri­on. Those drugs, Myalept and Jux­tapid, were note­wor­thy for con­sis­tent­ly rank­ing among the most ex­pen­sive drugs in the US, ac­cord­ing to a list main­tained by GoodRx. Am­ryt upped the price of both in Jan­u­ary by 9.9% — keep­ing with an Aege­ri­on prac­tice — and Myalept now is ranked as the high­est-priced drug.

The list does in­clude those, like gene ther­a­pies, that pa­tients re­ceive in the clin­ic, al­though a sep­a­rate re­port found Myalept was on­ly be­hind No­var­tis’ $2 mil­lion gene ther­a­py Zol­gens­ma in to­tal an­nu­al cost.

Com­pa­nies do not tra­di­tion­al­ly re­lease drug prices be­fore ap­proval and Am­ryt did not im­me­di­ate­ly re­spond to a re­quest for com­ment. Or­phan drugs, though, are tra­di­tion­al­ly among the high­est-priced, fu­eled in part by lim­it­ed com­pe­ti­tion. Around 1 in 20,000 peo­ple are es­ti­mat­ed to have EB.

Al­though ad­mit­ted­ly more a com­mer­cial com­pa­ny than a re­search one — “We’re not a re­search-based com­pa­ny, we don’t have labs any­where,” Wi­ley told End­points News last year — the com­pa­ny does have one oth­er treat­ment in the pipeline. In 2018, they in-li­censed a gene ther­a­py for epi­der­mol­y­sis bul­losa.

What does a clear ma­jor­i­ty of the bio­phar­ma in­dus­try think of the FDA ap­proval of ad­u­canum­ab? 'Hor­ri­fy­ing' 'Dan­ger­ous' 'Con­fus­ing' 'Dis­as­ter'

Over the years, we’ve become used to seeing a consensus emerge early in our industry polls at Endpoints News. And when we took the pulse of drug hunters on the heels of a controversial FDA approval for aducanumab this week, it became immediately apparent that the vast majority of our readers — heavily concentrated among biopharma staffers and execs — were incensed by what they had just witnessed.

Har­vard’s Aaron Kessel­heim re­signs from ex­pert pan­el in wake of ad­u­canum­ab OK, blast­ing FDA for ‘worst drug ap­proval de­ci­sion in re­cent U.S. his­to­ry'

A third member of the FDA’s Peripheral and Central Nervous System Drugs Advisory Committee has resigned in the wake of Biogen’s controversial Aduhelm approval, slamming the agency as he left and further deepening the controversy surrounding the decision.

Harvard University professor Aaron Kesselheim quit in protest Thursday afternoon, calling the Aduhelm OK “probably the worst drug approval decision in recent U.S. history.” Kesselheim follows both Joel Perlmutter, a neurologist from Washington University in St. Louis, and David Knopman, a neurologist from the Mayo Clinic, out the door.

A sec­ond ad­comm mem­ber aban­dons his post in af­ter­math of con­tro­ver­sial ad­u­canum­ab de­ci­sion

As the fallout from the FDA’s approval of Alzheimer’s med aducanumab grows, a second member of the adcomm overseeing that drug’s review has walked away. But even with two experts now having resigned from that committee in protest, is there enough broad-level outrage to prevent another aducanumab from getting approved?

The FDA on Wednesday lost another member of its Peripheral and Central Nervous System Drugs Advisory Committee as Mayo Clinic neurologist David Knopman hit the exit over the agency’s decision to approve Biogen’s Alzheimer’s drug Aduhelm despite the committee’s near-unanimous vote against it.

UP­DAT­ED: Ver­tex strikes out on its lat­est big shot at a rare ge­net­ic dis­ease. But they're go­ing to keep on swing­ing

It’s been several months since Vertex culled one of its small molecules for alpha-1 antitrypsin deficiency (AATD), taking a big hit after evidence of liver damage surfaced in a key Phase II trial. Now we learned that the company has whiffed on its second shot, and there’s nothing left in the clinic to treat the rare genetic disease — but that won’t stop it from trying.

Despite avoiding the safety issues that plagued the last candidate, Vertex $VRTX is taking the axe to VX-864 after Phase II results revealed the magnitude of the drug’s response is “unlikely to translate into substantial clinical benefit.” As a result of the news, the company’s stock fell 12.5% after hours.

FDA au­tho­rizes about 10M J&J vac­cine dos­es, trash­es 60M more from trou­bled Emer­gent plant

The FDA on Friday released about 10 million doses of J&J’s vaccine for use, and disposed of another 60 million doses that were manufactured at the now-shuttered Emergent BioSolutions facility in Baltimore where cross-contamination occurred.

The agency said it’s not yet ready to allow the Emergent plant to be included in the J&J EUA, but that may occur soon. FDA came to the decision to authorize some of the doses after reviewing facility records and quality testing results.

Months af­ter FDA re­jec­tion, Sanofi touts piv­otal win for rare dis­ease drug su­tim­limab as it preps to re­file

One of the pillar drugs of Sanofi’s $11.6 billion pickup of Bioverativ hit a big setback late last year when the FDA sent its application for approval back. Now, as Sanofi gears up to resubmit the drug for review, the drugmaker is touting pivotal data it hopes will help take it over the finish line.

Sanofi’s sutimlimab nailed all three of its primary endpoints in its Phase III CADENZA study for patients with cold agglutinin disease, a rare disorder that can cause severe anemia, without a recent history of blood transfusion, the French drugmaker said Friday. The topline results will be presented at this weekend’s virtual EHA meeting.

Ver­tex and CRISPR Ther­a­peu­tics un­veil more pos­i­tive gene ther­a­py da­ta, but busul­fan again casts a shad­ow over the field

Less than 12 hours after revealing a flop on its second shot for alpha-1 antitrypsin deficiency, Vertex plowed ahead with another data drop from its partnership with CRISPR Therapeutics. And though the topline proved positive, concerns over conditioning agents continue to linger over the collaboration, as well as the entire gene therapy space.

Presenting data from two trials at the European Hematology Association annual meeting, the pair announced that follow-up data of at least three months for 22 patients with genetic blood disorders indicated a “consistent and sustained” response to the experimental drug CTX001. All 15 patients with transfusion-dependent beta thalassemia did not need further blood transfusions and all seven with severe sickle cell disease were pain free, the biotechs announced.

Sen­a­tors lam­bast new Alzheimer’s drug’s price but give Janet Wood­cock a free pass on the ap­proval de­ci­sion

Senate Finance Democrats took aim at Biogen’s pricey new Alzheimer’s drug on Thursday, but members on both sides of the aisle at a separate appropriations hearing didn’t question acting FDA commissioner Janet Woodcock on the approval.

“I was appalled that Biogen priced their Alzheimer’s drug approved by the FDA at $56,000 per year — I’m not going to debate whether this is effective or not, but it’s double the household median income for Michiganders over the age of 65,” Sen. Debbie Stabenow (D-MI) said at the finance hearing.
