Af­ter thy­roid eye drug scores in PhI­II test, Hori­zon Phar­ma read­ies mar­ket­ing ap­pli­ca­tion

Less than two years af­ter Hori­zon Phar­ma $HZNP pro­cured phase III-ready thy­roid eye dis­ease (TED) drug tepro­tu­mum­ab for $145 mil­lion up­front by ac­quir­ing a unit of Nar­row Riv­er, biotech vet­er­an David Mad­den’s in­vest­ment firm — the bet has paid off, as the au­toim­mune in­flam­ma­to­ry dis­or­der drug passed its late-stage test on Thurs­day.

Tim Wal­bert, Hori­zon CEO

In TED pa­tients, the eye mus­cles and fat­ty tis­sue be­hind the eye be­come in­flamed, caus­ing the eyes to ap­pear to be ‘bulging’ and eye­lids to be­come swollen and red, even­tu­al­ly cul­mi­nat­ing in eye mis­align­ment, dou­ble vi­sion and in some cas­es even blind­ness — but there is lim­it­ed win­dow of up to three years dur­ing which the con­di­tion can be treat­ed with­out sur­gi­cal in­ter­ven­tion.

Tepro­tu­mum­ab is a mon­o­clon­al an­ti­body de­signed to in­hib­it in­sulin-like growth fac­tor 1 re­cep­tor (IGF-1R). In the 83-pa­tient phase III tri­al, 82.9% of pa­tients treat­ed with tepro­tu­mum­ab ex­pe­ri­enced a mean­ing­ful im­prove­ment in prop­to­sis or bulging of the eye (a 2 mm or more re­duc­tion (p<0.001)) com­pared to 9.5% of pa­tients on the place­bo — meet­ing the main goal of the study. All the sec­ondary end­points were al­so met, the com­pa­ny said.

The rare dis­ease drug­mak­er is work­ing on sub­mit­ting a mar­ket­ing ap­pli­ca­tion for tepro­tu­mum­ab by the mid­dle of 2019, it said. The FDA has grant­ed the ex­per­i­men­tal TED treat­ment — which was orig­i­nal­ly de­vel­oped by Gen­mab and sub­se­quent­ly li­censed from Roche — all the bells and whis­tles: break­through ther­a­py, or­phan drug and fast track des­ig­na­tions that should make a speedy re­view like­ly.

Ray­mond Dou­glas

“If ap­proved, tepro­tu­mum­ab would give physi­cians the first med­i­cine shown to re­duce prop­to­sis dur­ing ac­tive thy­roid eye dis­ease, in ad­di­tion to treat­ing oth­er painful symp­toms,” said Ray­mond Dou­glas, the study’s co-prin­ci­pal in­ves­ti­ga­tor and di­rec­tor of the or­bital and thy­roid eye dis­ease pro­gram at the Cedars-Sinai Med­ical Cen­ter, in a state­ment.

If the BLA is ac­cept­ed, the drug is po­si­tioned for launch in the first half of next year — giv­en the pos­si­bil­i­ty of pri­or­i­ty re­view, Jef­feries an­a­lyst David Stein­berg wrote in a note, adding that there are rough­ly 15,000 to 20,000 ac­tive TED US pa­tients el­i­gi­ble for treat­ment.

Stein­berg es­ti­mat­ed $500 mil­lion in peak sales of the drug by 2024, but added that Hori­zon man­age­ment has fore­cast $750 mil­lion, giv­en the drug has se­cured or­phan sta­tus and is dis­ease-mod­i­fy­ing — po­ten­tial­ly paving the way for ro­bust pric­ing.

Hori­zon cur­rent­ly sells the drug with the high­est price tag in the Unit­ed States — Ac­tim­mune.

“Giv­en the strong ex­e­cu­tion in the re­launch of Krys­texxa (a drug for chron­ic gout) and now on the cusp of in­tro­duc­ing an­oth­er long du­ra­tion or­phan drug with tepro, we in­creas­ing­ly see HZNP be­com­ing a leader in the rare dis­ease area,” Stein­berg wrote.

AveX­is sci­en­tif­ic founder fires back at No­var­tis CEO Vas Narasimhan, 'cat­e­gor­i­cal­ly de­nies any wrong­do­ing'

Brian Kaspar’s head was among the first to roll at Novartis after company execs became aware of the fact that manipulated data had been included in its application for Zolgensma, now the world’s most expensive therapy.

But in his first public response, the scientific founder at AveXis — acquired by Novartis for $8.7 billion — is firing back. And he says that not only was he not involved in any wrongdoing, he’s ready to defend his name as needed.

I reached out to Brian Kaspar after Novartis put out word that he and his brother Allen had been axed in mid-May, two months after the company became aware of the allegations related to manipulated data. His response came back through his attorneys.

UP­DAT­ED: An em­bold­ened As­traZeneca splurges $95M on a pri­or­i­ty re­view vouch­er. Where do they need the FDA to hus­tle up?

AstraZeneca is in a hurry.

We learned this morning that the pharma giant — not known as a big spender, until recently — forked over $95 million to get its hands on a priority review voucher from Sobi, otherwise known as Swedish Orphan Biovitrum.

That marks another step down on price for a PRV, which allows the holder to slash 4 months off of any FDA review time.

Pris­on­er #87850-053 does not get to add drug de­vel­op­er to his list of cred­its

Just days after Retrophin shed its last ties to founder Martin Shkreli, the biotech is reporting that the lead drug he co-invented flopped in a pivotal trial. Fosmetpantotenate flunked both the primary and key secondary endpoints in a placebo-controlled trial for a rare disease called pantothenate kinase-associated neurodegeneration, or PKAN.

We­bi­nar: Re­al World End­points — the brave new world com­ing in build­ing fran­chise ther­a­pies

Several biopharma companies have been working on expanding drug labels through the use of real world endpoints, combing through the data to find evidence of a drug’s efficacy for particular indications. But we’ve just begun. Real World Evidence is becoming an important part of every clinical development plan, in the soup-through-nuts approach used in building franchises.

I’ve recruited a panel of 3 top experts in the field — the first in a series of premium webinars — to look at the practical realities governing what can be done today, and where this is headed over the next few years, at the prodding of the FDA.

ZHEN SU — Merck Serono’s Senior Vice President and Global Head of Oncology
ELLIOTT LEVY — Amgen’s Senior Vice President of Global Development
CHRIS BOSHOFF — Pfizer Oncology’s Chief Development Officer

Am­gen, Al­ler­gan biosim­i­lar of Roche's block­buster Rit­ux­an clears an­oth­er US piv­otal study 

Novartis $NVS may have given up, but Amgen $AMGN and Allergan $AGN are plowing ahead with their knockoff of Roche’s blockbuster biologic Rituxan in the United States.

Their copycat, ABP 798, was found to have a clinically equivalent impact as Rituxan — meeting the main goal of the study involving CD20-positive B-cell non-Hodgkin’s lymphoma patients. This is the second trial supporting the profile of the biosimilar. In January, it came through with positive PK results in patients with rheumatoid arthritis.

BeiGene and Mus­tang nail down spe­cial FDA sta­tus for top drugs; Roche bags added cov­er­age for Hem­li­bra

→ BeiGene $BGNE is getting a boost in its drive to field a rival to Imbruvica. The FDA has offered an accelerated review to zanubrutinib, a BTK inhibitor that has posted positive results for mantle cell lymphoma. The PDUFA date lands on February 27, 2020. The drug scored breakthrough status at the beginning of the year.

→ BeiGene isn’t the only biopharma company to gain special regulatory status today. Mustang Bio $MBIO and St. Jude Children’s Research Hospital announced that MB-107, a lentiviral gene therapy for the treatment of X-linked severe combined immunodeficiency, also known as bubble boy disease, has been granted Regenerative Medicine Advanced Therapy status.

Trump ad­min­is­tra­tion re­vives bid to get drug list prices on TV ads

The Trump administration is not giving up just yet. On Wednesday, the HHS filed an appeal against a judge’s decision in July to overturn a ruling obligating drug manufacturers to disclose the list price of their therapies in television adverts — hours before it was stipulated to go into effect.

In May, the HHS published a final ruling requiring drugmakers to divulge the wholesale acquisition cost— of a 30-day supply of the drug — in tv ads in a bid to enhance price transparency in the United States. The pharmaceutical industry has vehemently opposed the rule, asserting that list prices are not what a typical patient in the United States pays for treatment — that number is typically determined by the type of (or lack thereof) insurance coverage, deductibles and out-of-pocket costs. Although there is truth to that claim, the move was considered symbolic in the Trump administration’s healthcare agenda to hold drugmakers accountable in a climate where skyrocketing drug prices have incensed Americans on both sides of the aisle.

Ver­sant-backed Chi­nook gets a $65M launch round for its dis­cov­ery quest in a resur­gent kid­ney field

Versant is once again stepping off the beaten track in biotech to see if they can blaze a trail of their own in a field that has looked too thorny to many investors for years.

The venture group and their partners at Apple Tree are bringing their latest creation out of stealth mode today. Born in Versant’s Inception Sciences’ Chinook Therapeutics is betting that its preclinical take on kidney disease can get an early lead among the companies starting up in the field.

Sir An­drew Dil­lon, NICE's first — and on­ly — chief ex­ec­u­tive to step down next year

Using a laptop borrowed from his former employer, South London’s St George’s Hospital, Sir Andrew Dillon set about establishing NICE — launched by the then health secretary Frank Dobson — in 1999.  On Thursday, the UK cost-effectiveness watchdog said its first and only chief executive — Dillon — is stepping down in March 2020.

Back in the day, decisions about which drugs and interventions were funded by the National Health Service (NHS) were made at the local level, but this ‘postcode prescribing’ system was fraught with skewed healthcare deployment making the structure unsustainable. A national system was deemed necessary — and NICE was formed to bridge that gap.
