Close­ly al­lied with (both) Mer­cks and Cel­gene, Sutro CEO Bill Newell is lay­ing out all his cards in a new IPO

Sutro CEO Bill Newell didn’t hide his in­ter­est in an IPO last year, af­ter he re­tooled a pact with Cel­gene that elim­i­nat­ed their buy­out op­tion and left the com­pa­ny free to pur­sue its own des­tiny. And with tens of mil­lions of Mer­ck dol­lars back­ing him af­ter their new can­cer drug part­ner­ship last month, he’s go­ing for it.

South San Fran­cis­co-based Sutro filed for a $75 mil­lion IPO last night, spelling out in con­sid­er­able de­tail how he’s been able to raise cash to grow the com­pa­ny from his plat­form part­ner­ships. In­vestors added an $85 mil­lion round a few days ago to top up the num­bers, bring­ing Sutro’s VC to­tal to $175 mil­lion.

There’s lots of cash and bil­lions in mile­stones to con­sid­er here.

We know now that in ad­di­tion to Mer­ck’s $60 mil­lion up­front in Ju­ly, the phar­ma gi­ant al­so bought $30 mil­lion in stock while com­mit­ting to $1.6 bil­lion in mile­stones. That of­fers a key Big Phar­ma en­dorse­ment for a plat­form that con­cen­trates heav­i­ly on a new gen­er­a­tion of can­cer-tar­get­ing an­ti­body-drug con­ju­gates and bis­pecifics. 

In the first three years of the 2014 Cel­gene deal, Sutro earned $167 mil­lion, then bagged an­oth­er $12.5 mil­lion in cash a year ago to fo­cus on four key pro­grams, an an­ti­body-drug con­ju­gate for BC­MA that leads the group. Cel­gene is us­ing their al­liance to sur­round mul­ti­ple myelo­ma from sev­er­al sides with dif­fer­ent part­ners. There are sev­er­al bis­pecifics in the deal, which are still not com­plete­ly in view, with an­oth­er $12.5 mil­lion due on the first IND clear­ance.

“We are ex­cit­ed about that tar­get for myelo­ma,” Newell told me last sum­mer. “Three dif­fer­ent modal­i­ties gives them dif­fer­ent pa­tients for whom dif­fer­ent ther­a­pies might be ap­pro­pri­ate. CAR-T is ex­cit­ing, but not all pa­tients will be el­i­gi­ble for CAR-T. They want to fo­cus on dif­fer­ent modal­i­ties.”

Mile­stones range from $295 mil­lion to $393.7 mil­lion, de­pend­ing on the drug.

An­oth­er set of IND-en­abling stud­ies is planned next year for their third strate­gic part­ner, Mer­ck KGaA, which has rights to six dif­fer­ent can­cer tar­gets. That pact has de­liv­ered $27 mil­lion in pay­ments and re­search sup­port.

While the part­ner­ships have helped the com­pa­ny grow, Sutro has been spot­light­ing the ear­ly clin­i­cal de­vel­op­ment of a lead ther­a­py dubbed STRO-001, an an­ti­body-drug con­ju­gate tar­get­ing CD74, which is ex­pressed on B cell ma­lig­nan­cies. And the com­pa­ny in­tends to con­tin­ue to build up its own pipeline.

Al­to­geth­er Sutro has nine dif­fer­ent in­vestors who own more than 5% of the stock, with Mer­ck on top with 12.5%. The rest of the group in­cludes Al­ta Part­ners, Cel­gene, Lil­ly and Sky­line Ven­tures as well as Vi­da Ven­tures.

A spin­out of theirs, SutroVax, is pur­su­ing a clin­i­cal quest aimed at con­quer­ing the pneu­mo­coc­cal con­ju­gate vac­cine busi­ness.

#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.

Deborah Dunsire. Lundbeck

UP­DAT­ED: Deb­o­rah Dun­sire is pay­ing $2B for a chance to leap di­rect­ly in­to a block­buster show­down with a few of the world's biggest phar­ma gi­ants

A year after taking the reins as CEO of Lundbeck, Deborah Dunsire is making a bold bid to beef up the Danish biotech’s portfolio of drugs in what will likely be a direct leap into an intense rivalry with a group of giants now carving up a growing market for new migraine drugs.

Bright and early European time Monday morning the company announced that it will pay up to about $2 billion to buy Alder, a little biotech that is far along the path in developing a quarterly IV formulation of a CGRP drug aimed at cutting back the number of crippling migraines patients experience each month. In a followup call, Dunsire also noted that the company will likely need 200 to 250 reps for this marketing task on both sides of the Atlantic. And analysts were quick to note that the dealmaking at Lundbeck isn’t done, with another $2 billion to $3 billion available for more deals to beef up the pipeline.

It’s fi­nal­ly over: Bio­gen, Ei­sai scrap big Alzheimer’s PhI­I­Is af­ter a pre­dictable BACE cat­a­stro­phe rais­es safe­ty fears

Months after analysts and investors called on Biogen and Eisai to scrap their BACE drug for Alzheimer’s and move on in the wake of a string of late-stage failures and rising safety fears, the partners have called it quits. And they said they were dropping the drug — elenbecestat — after the independent monitoring board raised concerns about…safety.

We don’t know exactly what researchers found in this latest catastrophe, but the companies noted in their release that investigators had determined that the drug was flunking the risk/benefit analysis.

Scott Got­tlieb has a new board po­si­tion to add to the re­sume — and this one is fo­cused on a fa­vorite sub­ject

Scott Gottlieb has another position to add to his lengthy roster of boards and advisory roles in the wake of his departure from the helm of the FDA.

He’ll be joining the advisory board of FasterCures, a think tank which former junk bond king Michael Milken set up to help drive more drugs to the market, looking to accelerate drug R&D. That’s a subject close to the heart of Gottlieb, who blazed a trail at the FDA focused on hustling up the process. That helped endear him to the industry, making him one of the most popular commissioners in FDA history.

Karyopharm lines up $150 mil­lion cash in­jec­tion to back con­tro­ver­sial drug launch

Karyopharm has entered into a royalty agreement worth up to $150 million to back the launch of their multiple myeloma drug — recently approved by the FDA over the objections of a majority of the agency’s outside experts.

The deal with HealthCare Royalty Partners, worth $75 million now and $75 million once certain regulatory and commercial milestones have been reached, will fund the commercialization of Karyopharm’s oral SINE compound Xpovio (selinexor) for patients with multiple myeloma who have already had at least four prior therapies. The money will help Karyopharm as it markets its newly approved drug and pushes through clinical trials testing the drug on refractory multiple myeloma patients with one to three therapies and patients with treatment-resistant diffuse large B-cell lymphoma. It will give Karyopharm a cushion through mid-2021.

Af­ter a run of CT­LA-4 com­bo fail­ures, sci­en­tists spot­light a way to make it work — in se­lect pa­tients

CTLA-4/PD-(L)1 combinations have been one of the El Dorados of oncology, its promise forever behind that next hill but apparently unattainable after a series of pivotal clinical failures. But researchers at New York’s Memorial Sloan Kettering Cancer Center and the Technical University of Munich think they may know how to fix what’s wrong and boost the drive to next-gen cancer combos.

In a preclinical animal research program, researchers found that within a cell, checkpoints rely on a specific molecule — RNA-sensing molecule RIG-I — to work. If that sounds familiar, it’s because it has already been identified as a target for boosting immune responses and was subject to at least one Phase I/II trial. Pfizer in December allied itself with Kineta with $15 million upfront and $505 million in potential milestones to develop RIG-I immunotherapies, and three years ago Merck purchased German upstart Rigontec for $137 million upfront and over $400 million in potential milestones for the same purpose.

Pur­due Phar­ma files for bank­rupt­cy as first step in $10B opi­oid set­tle­ment

It’s settled. Purdue Pharma has filed for bankruptcy as part of a deal that would see the OxyContin maker hand over $10 billion in cash and other contributions to mitigate the opioid crisis — without acknowledging any wrongdoing in the protracted epidemic that’s resulted in hundreds of thousands of deaths.

The announcement came two weeks after news of a proposed settlement surfaced and largely confirm what’s already been reported.

MSK picks brain can­cer ex­pert Lisa DeAn­ge­lis as its next CMO — fol­low­ing José Basel­ga’s con­tro­ver­sial ex­it

It’s official. Memorial Sloan Kettering has picked a brain cancer expert as its new physician-in-chief and CMO, replacing José Baselga, who left under a cloud after being singled out by The New York Times and ProPublica for failing to properly air his lucrative industry ties.

His replacement, who now will be in charge of MSK’s cutting-edge research work as well as the cancer care delivered by hundreds of practitioners, is Lisa M. DeAngelis. DeAngelis had been chair of the neurology department and co-founder of MSK’s brain tumor center and was moved in to the acting CMO role in the wake of Baselga’s departure.
