Shat­ter­ing an old record, FDA quick­ly OKs pi­o­neer­ing, site-ag­nos­tic can­cer drug larotrec­tinib from Loxo and Bay­er

The FDA has hus­tled up a quick OK for larotrec­tinib, of­fer­ing their stamp of ap­proval for a site-ag­nos­tic can­cer drug from Loxo On­col­o­gy and their part­ners at Bay­er, a prime ex­am­ple of a new wave of on­col­o­gy drugs hit­ting the field.

The la­bel for their drug, now called Vi­t­rakvi, was the first thing to hit Twit­ter af­ter the mar­ket closed, which you can see here.

Stam­ford, CT-based Loxo $LOXO — run by CEO Josh Bilenker — is one of the trail­blaz­ers in per­son­al­ized can­cer ther­a­pies where pa­tients are grouped not by the site of tu­mor de­vel­op­ment but by ge­net­ics — an ap­proach that calls for broad­er se­quenc­ing to ID the ge­net­ic mu­ta­tions un­der­pin­ning each pa­tients’ can­cer. That re­quires lots of work to iden­ti­fy pa­tients. But they have da­ta from a small piv­otal study to back up their break­through.


Specif­i­cal­ly there were 50 pa­tients — 43 adults and 12 chil­dren and adults with TRK fu­sion can­cer — with 12% com­plete and 64% par­tial re­spon­ders. That’s a high rate of suc­cess and it qual­i­fied for a pri­or­i­ty re­view at an agency that likes to press the met­al on new drug OKs — par­tic­u­lar­ly for can­cer.

Now comes the re­al­ly hard part. To find the few thou­sand US pa­tients that could ben­e­fit will re­quire can­cer pa­tients to get their DNA se­quenced, which is un­com­mon. Then theres the price. Bay­er set the whole­sale price at just un­der $400,000 a year, putting the oral drug in the most ex­pen­sive drug cat­e­go­ry. Then there’s a liq­uid for­mu­la­tion avail­able for cer­tain chil­dren at $132,000 a year.

Bay­er is al­so of­fer­ing a mon­ey-back guar­an­tee to pay­ers with as­sur­ances that pa­tient’s out-of-pock­et ex­po­sure will usu­al­ly be lim­it­ed to small sums.

An­drew Berens at Leerink ex­pects to see the num­bers add up over the years.

We see peak Vi­t­rakvi rev­enues in the US of ~$700mn by 2030, with an ad­di­tion­al ~$375mn op­por­tu­ni­ty avail­able for next-gen­er­a­tion TRK in­hibitor LOXO-195, de­signed specif­i­cal­ly to ad­dress re­sis­tance mu­ta­tions that emerge with larotrec­tinib use.

“Its ap­proval re­flects ad­vances in the use of bio­mark­ers to guide drug de­vel­op­ment and the more tar­get­ed de­liv­ery of med­i­cine,” not­ed FDA com­mis­sion­er Scott Got­tlieb, who likes to step in when the agency breaks new ground. “We now have the abil­i­ty to make sure that the right pa­tients get the right treat­ment at the right time. This type of drug de­vel­op­ment pro­gram, which en­rolled pa­tients with dif­fer­ent tu­mors but a com­mon gene mu­ta­tion, wouldn’t have been pos­si­ble a decade ago be­cause we knew a lot less about such can­cer mu­ta­tions.”

A few months af­ter the da­ta ar­rived Bay­er bought in, hand­ing over a $400 mil­lion up­front, with $450 mil­lion in mile­stones for the de­vel­op­ment and first sale of larotrec­tinib, with an­oth­er $200 mil­lion on the ta­ble for LOXO-195. There’s al­so $500 mil­lion on the books for com­mer­cial goals.

Mer­ck was the first to score in this site-ag­nos­tic field, win­ning an FDA OK last year to use Keytru­da against tu­mors that were mi­crosatel­lite in­sta­bil­i­ty-high or char­ac­ter­ized by mis­match re­pair de­fi­cien­cy.

This is the 53rd new drug ap­proval for the FDA’s CDER, which with sev­er­al new bi­o­log­ic OKs this year has shat­tered the record to­tal of 53 drugs ap­proved in 1996. With 5 weeks to go in the year, the agency has plen­ty of time to set a brand new bar for pro­duc­tiv­i­ty in bio­phar­ma R&D.

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.
