Genen­tech inks $650M deal with pro­tein degra­da­tion pi­o­neer Arv­inas

Genen­tech is dou­bling down on its com­mit­ment to New Haven biotech Arv­inas, ex­tend­ing the duo’s part­ner­ship and tack­ing an ad­di­tion­al $350 mil­lion on­to the to­tal deal val­ue.

The com­pa­nies have been work­ing to­geth­er since 2015, with Genen­tech li­cens­ing Arv­inas’ plat­form for pro­tein degra­da­tion to do some se­cre­tive R&D. Back then, Genen­tech wasn’t dis­clos­ing its dis­ease tar­gets, and it still isn’t. They’re on­ly telling us that the new deal in­cludes ad­di­tion­al tar­gets in “mul­ti­ple ther­a­peu­tic ar­eas.”

Un­der the re­vised terms, Arv­inas can re­ceive mile­stone pay­ments in ex­cess of $650 mil­lion. When the deal was first an­nounced, the pack­age in­clud­ed $300 mil­lion in po­ten­tial mile­stones.

John Hous­ton

What has Genen­tech so in­ter­est­ed? Arv­inas is a bit of a pi­o­neer in a new modal­i­ty called pro­tein degra­da­tion. Arv­inas’ CEO John Hous­ton tells me the com­pa­ny was the first to take the con­cept be­yond acad­e­mia. The sci­ence has since gained pop­u­lar­i­ty, with com­pa­nies like C4 Ther­a­peu­tics and Kymera jump­ing on board. Even ma­jor phar­mas like Cel­gene, Take­da, GSK and No­var­tis have ef­forts in the space.

The con­cept be­hind pro­tein degra­da­tion is sim­ple enough. Where pro­tein in­hi­bi­tion has led to some ad­vanced med­i­cines, de­grad­ing pro­teins could prove a much more durable so­lu­tion. In short, Arv­inas plans to tag cer­tain dis­ease-caus­ing pro­teins for de­struc­tion by re­cruit­ing an E3 lig­ase to the tar­get, there­by send­ing the pro­tein to the cell’s nat­ur­al “garbage dis­pos­al” called the ubiq­ui­tin-pro­tea­some sys­tem.

Hous­ton said the plat­form, in the­o­ry, could be wide­ly ap­plic­a­ble to sev­er­al dis­eases.

“We’re not lim­it­ed by dis­ease area, as al­most any dis­ease with a cell you want to de­grade could be tar­get­ed,” Hous­ton said.

Still, the com­pa­ny is start­ing with two main pro­grams for an­dro­gen and es­tro­gen re­cep­tor degra­da­tion for prostate and breast can­cer. They’re work­ing on a pair of INDs and look­ing to get in­to the clin­ic by 2018, al­though the com­pa­ny’s breast can­cer pro­gram may get there a tad ear­li­er.

Hous­ton said af­ter these two tar­gets, Arv­inas may pur­sue lung can­cer and melanoma. Fur­ther in the fu­ture, Hous­ton (who used to run neu­ro­sciences at Bris­tol-My­ers) said he’d like to see the com­pa­ny take on neu­rode­gen­er­a­tion, as well.

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.

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.

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

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.

Pfiz­er is mak­ing a $500M state­ment to­day: Here’s how you be­come a lead play­er in the boom­ing gene ther­a­py sec­tor

Three years ago, Pfizer anted up $150 million in cash to buy Bamboo Therapeutics in Chapel Hill, NC as it cautiously stuck a toe in the small gene therapy pool of research and development.

Company execs followed up a year later with a $100 million expansion of the manufacturing operations they picked up in that deal for the UNC spinout, which came with $495 million in milestones.

And now they’re really going for it.

Video: Putting the AI in R&D — with Badhri Srini­vasan, Tony Wood, Rosana Kapeller, Hugo Ceule­mans, Saurabh Sa­ha and Shoibal Dat­ta

During BIO this year, I had a chance to moderate a panel among some of the top tech experts in biopharma on their real-world use of artificial intelligence in R&D. There’s been a lot said about the potential of AI, but I wanted to explore more about what some of the larger players are actually doing with this technology today, and how they see it advancing in the future. It was a fascinating exchange, which you can see here. The transcript has been edited for brevity and clarity. — John Carroll

UP­DAT­ED: As­traZeneca’s Imfinzi/treme com­bo strikes out — again — in lung can­cer. Is it time for last rites?

AstraZeneca bet big on the future of their PD-L1 Imfinzi combined with the experimental CTLA-4 drug tremelimumab. But once again it’s gone down to defeat in a major Phase III study — while adding damage to the theory involving targeting cancer with a high tumor mutational burden.

Early Wednesday the pharma giant announced that their NEPTUNE study had failed, with the combination unable to beat standard chemo at overall survival in high TMB cases of advanced non-small cell lung cancer. We won’t get hard data until later in the year, but the drumbeat of failures will call into question what — if any — future this combination can have left.

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.
