GSK bags Tesaro for $5B as it leaps back in­to com­mer­cial on­col­o­gy and beefs up can­cer drug pipeline

Glax­o­SmithK­line has struck a deal to buy Tesaro $TSRO in a $5.1 bil­lion deal that will vault the phar­ma gi­ant in­to the com­mer­cial on­col­o­gy mar­ket as it stakes out a big new role for it­self in the boom­ing can­cer field.

Long dis­cussed af­ter Tesaro man­age­ment put out the word on sev­er­al oc­ca­sions in the past year that it was look­ing to sell the com­pa­ny and its PARP in­hibitor Ze­ju­la, GSK is pay­ing $75 a share, trig­ger­ing an in­stant 60% spike in the stock this morn­ing as in­vestors caught up to the news to­day.

Wait­ing out the ear­ly buzz al­lowed GSK to pick this com­pa­ny up for a rel­a­tive bar­gain. Tesaro start­ed 2018 at $82 a share, but watched its share price slide 42% un­til to­day as an­a­lysts beat them up over their poor sales per­for­mance. In ear­ly 2017, the stock hit a high of $190. That helps ex­plain why Tesaro was nev­er able to suc­ceed at auc­tion­ing the com­pa­ny ear­li­er, when its share price was still in­flat­ed.

Ze­ju­la is one of sev­er­al PARPs to hit the mar­ket af­ter As­traZeneca pi­o­neered the field with the first ap­proval for Lyn­parza, though lit­tle Tesaro has strug­gled to play catch-up along­side Clo­vis and Pfiz­er, which won a re­cent ap­proval for its PARP, ob­tained in the Medi­va­tion buy­out.

It won’t be easy. As­traZeneca and its new part­ners at Mer­ck have poured re­sources in­to the Lyn­parza fran­chise, win­ning block­buster re­turns as they widen their lead over the pack. And the ac­qui­si­tion wasn’t ex­act­ly cheered by GSK in­vestors, who drove the stock down a painful 8% af­ter the news hit.

The ac­qui­si­tion, though, gives Hal Bar­ron’s resur­gent can­cer re­search group un­der Ax­el Hoos a new drug to work with, as GSK pur­sues new in­di­ca­tions in a range of clin­i­cal tri­als aimed at ex­pand­ing its mar­ket pres­ence in on­col­o­gy.

GSK is just now jump­ing back in­to the com­mer­cial can­cer field af­ter strik­ing a deal with No­var­tis to flip its late-stage and mar­ket­ed on­col­o­gy prod­ucts for a port­fo­lio of vac­cines.

The move comes about a year af­ter Bar­ron — who had a leg­endary run at Genen­tech — took the top R&D job at GSK. As he told me ear­li­er this year, his new team — in­clud­ing new BD chief Kevin Sin — was hard at it scour­ing the globe for deals that made sense for the com­pa­ny.

At this point, a weary Tesaro and Ze­ju­la looked un­der­val­ued. And that made it a prime tar­get for the phar­ma com­pa­ny. GSK has been a ma­jor play­er in HIV and vac­cines, but its phar­ma R&D ops are the weak­est in its heavy­weight class.

This new deal brings a pipeline that al­so adds a PD-1 — one in a tidal wave of check­points — as well as TIM-3 and LAG-3 as­sets, which are al­so not so un­com­mon. In the mean­time, Bar­ron made it clear in a call with re­porters this morn­ing that he was ea­ger to see about the po­ten­tial to ex­pand Ze­ju­la in­to the broad­er HRD-pos­i­tive com­mu­ni­ty, which would dra­mat­i­cal­ly in­crease the size of the mar­ket.

PARPs work by in­ter­fer­ing with DNA re­pair mech­a­nisms that al­low can­cer cells to sur­vive, open­ing up an av­enue that could re­late to a va­ri­ety of can­cers.

So what hap­pens to the 800 or so staffers at Tesaro? 

Em­ma Walm­s­ley

In a call with re­porters Mon­day morn­ing, CEO Em­ma Walm­s­ley not­ed that the deal wasn’t be­ing dri­ven by cost syn­er­gies and al­so brings com­mer­cial ca­pa­bil­i­ties back to a com­pa­ny that cur­rent­ly doesn’t have an on­col­o­gy sales force. In time, she added, they’ll look at syn­er­gies — code for cuts — but it’s ear­ly days on that.

Walm­s­ley al­so de­clined to say just what kind of peak sales they can ex­pect from Ze­ju­la. In the past, though, peak sales es­ti­mates have climbed to $2 bil­lion.

“Our strong be­lief is that PARP in­hibitors are im­por­tant med­i­cines that have been un­der ap­pre­ci­at­ed in terms of the im­pact they can have on can­cer pa­tients,” Bar­ron not­ed in a state­ment. “We are op­ti­mistic that Ze­ju­la will demon­strate ben­e­fit in pa­tients with ovar­i­an can­cer be­yond those who are BR­CA-pos­i­tive as front-line treat­ment. We are al­so very ex­cit­ed that through this trans­ac­tion, we will have the op­por­tu­ni­ty to work with an out­stand­ing Boston-based on­col­o­gy group with deep clin­i­cal de­vel­op­ment ex­per­tise and to­geth­er we will ex­plore Ze­ju­la’s ef­fi­ca­cy be­yond ovar­i­an can­cer in­to mul­ti­ple tu­mour types to help many more pa­tients.”


Im­age: Ax­el Hoos, Hal Bar­ron, John Lep­ore, Kevin Sin and Tony Wood.

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.
