Glax­o­SmithK­line sets its sights on a quick leap in­to the big PD-1/L1 game — will any­one no­tice?

Some­what lost in the news last fall that Glax­o­SmithK­line was buy­ing Tesaro and leap­ing in­to the com­mer­cial end of the chal­leng­ing PARP mar­ket was a PD-1 check­point in­hibitor called TSR-042 that was be­ing point­ed to a quick fil­ing for en­dome­tri­al can­cer. On Tues­day, the GSK sub­sidiary spot­light­ed a promis­ing set of Phase I/II da­ta from their GAR­NET study, and the fil­ing is on track for lat­er this year as the phar­ma gi­ant looks to make its own en­try in­to an in­creas­ing­ly crowd­ed field.

Hal Bar­ron

The snap­shot for the new­ly dubbed dostar­limab: Over­all re­sponse rates in the full pop­u­la­tion of 125 women with a com­mon form of gy­ne­co­log­i­cal can­cer — then bro­ken in­to mi­crosatel­lite in­sta­bil­i­ty-high (MSI-H) and mi­crosatel­lite sta­ble (MSS) pa­tients — were 30%, 49%, and 20%, re­spec­tive­ly. “Dis­ease con­trol rate in the full pop­u­la­tion, MSI-H pop­u­la­tion, and MSS pop­u­la­tion was 53%, 63% and 47%, re­spec­tive­ly.”

It’s a small, ear­ly study, but the ma­jors in the field have been giv­en the green light for less.

In on­col­o­gy, any op­por­tu­ni­ty to use a new drug to help pa­tients is gen­er­al­ly avid­ly wel­comed. And GSK’s re­lease notes that there’s on­ly one ap­proved drug for the same set­ting in en­dome­tri­al can­cer, giv­ing them at least a leg up as ri­vals like Mer­ck fol­low up with their own check­point com­bo ap­proach­es.

It’s easy, though, to over­look an­oth­er quick en­try on the PD-1/L1 front. There are six ap­proved in the US, two that reg­is­ter mega block­buster sta­tus, a new ar­rival from Re­gen­eron sup­port­ed by a re­search chief known to bring a lit­tle fire and brim­stone to his lead­ing drug can­di­dates, and sev­er­al al­so rans, with Baven­cio from Pfiz­er/Mer­ck KGaA — which is rais­ing eye­brows af­ter a long string of clin­i­cal duds. And then there are the mul­ti­tude of new drugs com­ing up from be­hind, and from mul­ti­ple con­ti­nents.

Ax­el Hoos

GSK’s chal­lenge will be to grab at­ten­tion as a play­er, with Hal Bar­ron lead­ing the charge and Ax­el Hoos play­ing the lead role in can­cer. The phar­ma gi­ant is promis­ing to trans­form it­self in­to a heavy­weight in on­col­o­gy, af­ter es­sen­tial­ly miss­ing out on the can­cer rev­o­lu­tion that has shak­en the in­dus­try for the past 5 years. And a PD-1 back­bone drug can play a big part.

What’s in­ter­est­ing, though, is how lit­tle at­ten­tion they’re get­ting for their work. As­traZeneca and Mer­ck rule the PARP roost with Lyn­parza, grow­ing stronger at seem­ing­ly every turn. And Mer­ck’s Keytru­da is clear­ly the dom­i­nant drug in the PD-1/L1 crowd.

Play­ing in the back of this busy field won’t be easy. But no one is count­ing Bar­ron out.

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

Hal Barron. GSK

GSK's Hal Bar­ron her­alds their sec­ond pos­i­tive piv­otal for cru­cial an­ti-BC­MA ther­a­py, point­ing to a push for quick OKs in a crowd­ed field

Hal Barron has his second positive round of Phase III data in hand for his anti-BCMA antibody drug conjugate belantamab mafodotin (GSK2857916). And GSK’s research chief says the data paves the way for their drive in search of an FDA approval for treating multiple myeloma.

It’s hard to overestimate the importance of this drug for GSK, a cornerstone of Barron’s campaign to make a dramatic impact on the oncology market and provide some long-lost excitement for the pharma giant’s pipeline. They’re putting this BCMA program at the front of that charge — looking to lead a host of rivals all aimed at the same target.

We don’t know what the data are yet, but DREAMM-2 falls on the heels of a promising set of data delivered 5 months ago for DREAMM-1. There investigators noted that complete responses among treatment-resistant patients rose to 15% in the extra year’s worth of data to look over, with a median progression-free survival rate of 12 months, up from 7.9 months reported earlier. The median duration of response was 14.3 months.

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.

Why would Am­gen want to buy Alex­ion? An­a­lysts call hot­ly ru­mored takeover un­like­ly, but seize the mo­ment

A rumor that Amgen is closing in on buyout deal for Alexion has sparked a guessing game on just what kind of M&A strategy Amgen is pursuing and how much Alexion is worth.

Mizuho analyst Salim Syed first lent credence to the report out of the Spanish news outlet Intereconomía, which said Amgen is bidding as much as $200 per share. While the source may be questionable, “the concept of this happening doesn’t sound too crazy to me,” he wrote.

FDA asks why No­var­tis took two months to launch for­mal in­ter­nal probe, af­ter AveX­is flagged da­ta ma­nip­u­la­tion

And the plot thickens. Novartis $NVS officials are reportedly now scrambling to explain to the FDA why it took them two months to open an internal investigation into data discrepancies for their $2.1 million gene-therapy for spinal muscular dystrophy — the world’s most expensive drug.

Build­ing on suc­cess­ful PD-1 pact, Eli Lil­ly li­cens­es di­a­betes drug to Chi­nese part­ners at In­novent

Eli Lilly is expanding its partnership with China’s Innovent in a deal involving a diabetes drug sitting in its Phase I reserves.

The two companies had jointly developed one of China’s first homegrown PD-1 agents, scoring an approval for Tyvyt (sintilimab) late last year for relapsed/refractory classical Hodgkin’s lymphoma. This time around, Lilly is out-licensing a piece of its diabetes pipeline, a leading franchise that has historically produced the top-selling Trulicity and Humalog.

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.

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.
