TCR deal spree in­ten­si­fies as Roche com­mits up to $2B in Adap­tive Biotech to de­vel­op per­son­al­ized can­cer drugs

The ap­petite for TCR ther­a­pies and their po­ten­tial to tar­get sol­id tu­mors — a lim­i­ta­tion of ex­ist­ing cel­lu­lar ther­a­pies — has bur­geoned, fu­el­ing a string of deals.  On Fri­day, Roche’s Genen­tech agreed to fork out a meaty $300 mil­lion up­front for ac­cess to Adap­tive Biotech­nolo­gies’ tech plat­form, which is de­signed to iden­ti­fy T-cell re­cep­tors (TCRs) for ther­a­peu­tic use. The deal, which of­fers Adap­tive up to $2 bil­lion over time in mile­stone pay­ments, will be used to de­vel­op per­son­al­ized can­cer ther­a­pies.

One of the key com­po­nents of the im­mune sys­tem are T cells, which oblit­er­ate can­cer cells by us­ing T cell re­cep­tor (TCR) recog­ni­tion of cell sur­face mark­ers known as anti­gens. When a T cell rec­og­nizes a tu­mor anti­gen via the TCR, it snuffs the ma­lig­nant cell on which it re­sides. TCR tech typ­i­cal­ly in­volves reengi­neer­ing T-cell re­cep­tors so that they can bet­ter rec­og­nize can­cer pro­teins, spark­ing an as­sault on tu­mors. Un­like CAR-T cells that can rec­og­nize ab­nor­mal pro­teins ex­pressed on the sur­face, TCRs can rec­og­nize tu­mor-spe­cif­ic pro­teins on the in­side of cells. That makes CAR-T ther­a­pies more amenable to blood can­cers, while TCR ther­a­pies-in-de­vel­op­ment have po­ten­tial across mul­ti­ple tu­mors.

Genen­tech is hop­ing Adap­tive’s plat­form — TruT­CR — will iden­ti­fy TCRs that can ef­fec­tive­ly rec­og­nize and tar­get spe­cif­ic neoanti­gens, which are pro­teins gen­er­at­ed by tu­mor-spe­cif­ic mu­ta­tions not found in nor­mal tis­sues. Es­sen­tial­ly, Adap­tive aims to use its tech­nol­o­gy to iso­late op­ti­mal TCRs that will most ef­fec­tive­ly tar­get each pa­tient’s neoanti­gens for treat­ment, while Genen­tech will en­gi­neer and man­u­fac­ture the tai­lored cel­lu­lar med­i­cine for the pa­tient.

“Cel­lu­lar ther­a­py ap­proach­es in can­cer have been lim­it­ed by the in­abil­i­ty to ef­fec­tive­ly screen and trans­late the im­mune re­sponse to pa­tient-spe­cif­ic neoanti­gens. Ac­cu­rate recog­ni­tion of such neoanti­gens is a ma­jor dri­ver in the ac­tiv­i­ty of nov­el im­munother­a­pies,” said Adap­tive co-founder Har­lan Robins in a state­ment.

Un­der the deal — ex­pect­ed to close in the first quar­ter of 2019 — Genen­tech is in charge of the clin­i­cal and reg­u­la­to­ry process as well as com­mer­cial­iza­tion, while Adap­tive is re­spon­si­ble for pa­tient-spe­cif­ic screen­ing.

There were a spate of TCR deals and an­nounce­ments in 2018: TCR2 Ther­a­peu­tics is plan­ning a $100 mil­lion-plus IPO, Gilead-owned CAR-T play­er Kite Phar­ma has paid $10 mil­lion to ac­cess Hi­FiBiO’s TCR tech plat­form, blue­bird bio tied up with neoanti­gen biotech Grit­stone to look for new tar­gets to beef up its TCR pipeline, and joined forces with Re­gen­eron to de­vel­op TCR tar­gets in a five-year al­liance.

Genen­tech sub­mits a big plan to ex­pand its South San Fran­cis­co foot­print

The sign is still there, a quaint reminder of whitewashed concrete not 5 miles from Genentech’s sprawling, chrome-and-glass campus: South Francisco The Industrial City. 

The city keeps the old sign, first erected in 1923, as a tourist site and a kind of civic memento to the days it packed meat, milled lumber and burned enough steel to earn the moniker “Smokestack of the Peninsula.” But the real indication of where you are and how much has changed both in San Francisco and in the global economy since a couple researchers and investors rented out an empty warehouse 40 years ago comes in a far smaller blue sign, resembling a Rotary Club post, off the highway: South San Francisco, The Birthplace of Biotech.

Here comes the oral GLP-1 drug for di­a­betes — but No­vo Nordisk is­n't dis­clos­ing Ry­bel­sus price just yet

Novo Nordisk’s priority review voucher on oral semaglutide has paid off. The FDA approval for the GLP-1 drug hit late Friday morning, around six months after the NDA filing.

Rybelsus will be the first GLP-1 pill to enter the type 2 diabetes market — a compelling offering that analysts have pegged as a blockbuster drug with sales estimates ranging from $2 billion to $5 billion.

Ozempic, the once-weekly injectable formulation of semaglutide, brought in around $552 million (DKK 3.75 billion) in the first half of 2019.

As Nas­daq en­rolls the fi­nal batch of 2019 IPOs, how have the num­bers com­pared to past years?

IGM Biosciences’ upsized IPO haul, coming after SpringWorks’ sizable public debut, has revved up some momentum for the last rush of biotech IPOs in 2019.

With 39 new listings on the books and roughly two more months to go before winding down, Nasdaq’s head of healthcare listings Jordan Saxe sees the exchange marking 50 to 60 biopharma IPOs for the year.

“December 15 is usually the last possible day that companies will price,” he said, as companies get ready for business talks at the annual JP Morgan Healthcare Conference in January.

Oxitec biologist releases genetically modified mosquitoes in Piracicaba, Brazil in 2016 [credit: Getty Images]

In­trex­on unit push­es back against claims its GM mos­qui­toes are mak­ing dis­ease-friend­ly mu­tants

When the hysteria of Zika transmission sprang into the American zeitgeist a few years ago, UK-based Oxitec was already field-testing its male Aedes aegypti mosquito, crafted to possess a gene engineered to obliterate its progeny long before maturation.

But when a group of independent scientists evaluated the impact of the release of these genetically-modified mosquitoes in a trial conducted by Oxitec in Brazil between 2013 and 2015, they found that some of the offspring had managed to survive — prompting them to speculate what impact the survivors could have on disease transmission and/or insecticide resistance.

Pur­due threat­ens to walk away from set­tle­ment, asks to pay em­ploy­ees mil­lions in bonus­es

There are two updates on the lawsuit against Purdue Pharma over its role in fueling the opioid epidemic, as the Sackler family threatens to walk away from their pledge to pay out $3 billion if a bankruptcy judge does not stop outstanding state lawsuits against them. At the same time, the company has asked permission to pay millions in bonuses to select employees.

Purdue filed for chapter 11 bankruptcy this week as part of its signed resolution to over 2,000 lawsuits. The deal would see the Sackler family that owns Purdue give $3 billion from their personal wealth and the company turned into a trust committed to curbing and reversing overdoses.

'Dis­con­nect the bas­tard­s' — one biotech's plan to break can­cer cell­s' uni­fied de­fens­es

Chemotherapy and radiotherapy are the current gladiators of cancer treatment, but they come with well-known limitations and side-effects. The emergence of immunotherapy — a ferocious new titan in oncologist’s toolbox — takes the brakes off the immune system to kill cancer cells with remarkable success in some cases, but the approach is not always effective. What makes certain forms of cancer so resilient? Scientists may have finally pieced together a tantalizing piece of the puzzle, and a new biotech is banking on a new approach to fill the gap.

Scott Got­tlieb is once again join­ing a team that en­joyed good times at the FDA un­der his high-en­er­gy stint at the helm

Right after jumping on Michael Milken’s FasterCures board on Monday, the newly departed FDA commissioner is back today with news about another life sciences board post that gives him a ringside chair to cheer on a lead player in the real-world evidence movement — one with very close ties to the FDA.

Aetion is reporting this morning that Gottlieb is joining their board, a group that includes Mohamad Makhzoumi, a general partner at New Enterprise Associates, where Gottlieb returned after stepping out of his role at the FDA 2 years after he started.

Gottlieb — one of the best connected execs in biopharma — knows this company well. As head of FDA he championed the use of real-world evidence to help guide drug developers and the agency in gaining greater efficiencies, which helped set up Aetion as a high-profile player in the game.

#UK­BIO19: Join GSK’s Hal Bar­ron and a group of top biotech ex­ecs for our 2nd an­nu­al biotech sum­mit in Lon­don

Over the past 10 years I’ve made a point of getting to know the Golden Triangle and the special role the UK biopharma industry plays there in drug development. The concentration of world class research institutes, some of the most accomplished scientists I’ve ever seen at work and a rising tide of global investment cash leaves an impression that there’s much, much more to come as biotech hubs are birthed and nurtured.
