What's up at stealthy Cal­i­co Labs? AI star Daphne Koller makes an abrupt ex­it as top team shrinks

Daphne Koller

When the not­ed AI ex­pert and ex-Stan­ford star Daphne Koller was re­cruit­ed to Google’s Cal­i­co Labs in 2016, it fit in­to an up­beat nar­ra­tive about how Arthur Levin­son was build­ing an amaz­ing team of top pro­fes­sion­als to pi­o­neer an­ti-ag­ing re­search. A few days ago, though, Koller abrupt­ly left the com­pa­ny and that nar­ra­tive is get­ting some fresh scruti­ny in R&D cir­cles.

“I have de­cid­ed to leave Cal­i­co to pur­sue oth­er pro­fes­sion­al op­por­tu­ni­ties,” Koller said in an emailed state­ment to Bloomberg, which first re­port­ed the de­par­ture. “I very much en­joyed my time at Cal­i­co, and have the great­est re­spect for the Cal­i­co team and their im­por­tant and as­pi­ra­tional mis­sion.”

This is the sec­ond big de­fec­tion for Cal­i­co in re­cent months. Top sci­en­tist Hal Bar­ron jumped to helm the R&D group at Glax­o­SmithK­line. But Bar­ron was wooed away with a top job and a turn­around mis­sion, with a mul­ti­mil­lion-dol­lar an­nu­al pay pack­age and his own of­fice in the Bay Area, where GSK has lit­tle pres­ence.

Arthur Levin­son

Koller had on­ly re­cent­ly at­tract­ed at­ten­tion for her dis­cus­sion of new mouse da­ta they were ac­cu­mu­lat­ing in the lab, part of a pricey ef­fort to de­vel­op new ther­a­pies that could make longer lives health­i­er. That was a de­par­ture for Cal­i­co, which has kept its head down low since Levin­son was brought in by Google’s Lar­ry Page to build the com­pa­ny.

More re­cent­ly, there were some ru­mors cir­cu­lat­ing in the AI world that Koller had grown some­what dis­en­chant­ed with Cal­i­co.

That cer­tain­ly wasn’t part of her pub­lic pro­file, though. Here’s a com­ment from Koller’s LinkedIn page.

Cal­i­co al­lowed me to re­turn to my pas­sion of ap­ply­ing ma­chine learn­ing to im­prove hu­man health. As Cal­i­co’s first Chief Com­put­ing Of­fi­cer, I built an amaz­ing team work­ing on new com­pu­ta­tion­al meth­ods for an­a­lyz­ing bi­o­log­i­cal da­ta sets to help bet­ter un­der­stand the process of ag­ing and de­vel­op­ing in­ter­ven­tions that en­able peo­ple to live longer, health­i­er lives.

The use of new ar­ti­fi­cial in­tel­li­gence tech in drug dis­cov­ery is fast be­com­ing one of the biggest trends in drug R&D as the ma­jors start to de­vel­op am­bi­tious in­ter­nal ef­forts to find a faster and more ef­fi­cient way to iden­ti­fy po­ten­tial break­throughs. But it still has a long way to go be­fore it can prove it­self to the in­dus­try.

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.

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.

Genen­tech sub­mits a plan to near­ly dou­ble 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.

Analysts hate to lose a biotech CFO they’ve come to trust and admire — especially if they’re being blindsided by a surprise exit.

'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.

While No­var­tis ban­ish­es Zol­gens­ma scan­dal scars — Bio­gen goes on a Spin­raza 'of­fen­sive'

While Novartis painstakingly works to mop up the stench of the data manipulation scandal associated with its expensive gene therapy for spinal muscular atrophy (SMA) Zolgensma— rival Biogen is attempting to expand the use of its SMA therapy, Spinraza. 

The US drugmaker $BIIB secured US approval for Spinraza for use in the often fatal genetic disease in 2016. The approval covered a broad range of patients with infantile-onset (most likely to develop Type 1) SMA.

UP­DAT­ED: Speak­er Nan­cy Pelosi to un­veil bill for fed­er­al­ly ne­go­ti­at­ed drug prices

After months of buzz from both sides of the aisle, Speaker Nancy Pelosi will today introduce her plan to allow the federal government to negotiate prices for 250 prescription drugs, setting up a showdown with a pharmaceutical industry working overtime to prevent it.

The need to limit drug prices is a rare point of agreement between President Trump and Democrats, although the president has yet to comment on the proposal and will likely face pressure to back a more conservative option or no bill at all. Republican Senator Chuck Grassley is reportedly lobbying his fellow party members on a more modest proposal he negotiated with Democratic Senator Ron Wyden in July.
