#ASH17: Seat­tle Ge­net­ics CEO Clay Sie­gall has an an­swer for the skep­tics doubt­ing Ad­cetris da­ta for Hodgkin lym­phoma

Seat­tle Ge­net­ics $SGEN CEO Clay Sie­gall ran in­to a wall of skep­ti­cism last sum­mer when he rolled out pos­i­tive da­ta from their Phase III study of a new cock­tail for front­line Hodgkin lym­phoma. Drop­ping the tox­ic bleomycin from the stan­dard chemo com­bo used to treat the dis­ease, re­searchers for the biotech — part­nered with Take­da — had come up with a lean but sig­nif­i­cant 5-point PFS ad­van­tage for the com­pa­ny’s flag­ship ther­a­py.

But in an era of sharp pay­er kick­backs for mar­gin­al­ly im­pres­sive drugs, the stock wilt­ed as the doubters pounced on the two-year mod­i­fied PFS rate of 82.1% com­pared to 77.2% in the con­trol arm — a 4.9 point, or 6%, im­prove­ment.

Sie­gall, how­ev­er, ar­rived in At­lanta this week­end for ASH con­fi­dent that reg­u­la­tors would fa­vor a pro­gram stamped with their “break­through” des­ig­na­tion. Pay­ers would see the ben­e­fits, he added, with the full pack­age of da­ta from ECH­E­LON-1. And physi­cians and pa­tients, he felt, are clear­ly will­ing to em­brace the change, par­tic­u­lar­ly as the da­ta are be­ing pre­sent­ed si­mul­ta­ne­ous­ly now in the pres­ti­gious New Eng­land Jour­nal of Med­i­cine.

First, he told me, there’s the sta­tis­ti­cal­ly sig­nif­i­cant ad­di­tion of longterm, dis­ease-free sur­vival of­fer­ing more pa­tients a shot at a po­ten­tial­ly cu­ra­tive so­lu­tion to their dis­ease. Drop­ping bleomycin, he adds, is a clear ben­e­fit. Even at a small rate of pul­monary tox­i­c­i­ty, it can be lethal. Carv­ing it out of the treat­ment reg­i­men will be cheered by every ex­pert in the field.

By physi­cians in­volved in the tri­al, the PFS ad­van­tage was 6.3%, with a 27% drop in the risk of dis­ease pro­gres­sion, death or need for an­oth­er drug.

“Can we get 5%, 6%, 7% more pa­tients cured, elim­i­nate bleomycin and lessen the num­ber of pa­tients with sec­ond rounds of chemo and ra­di­a­tion ther­a­py?” says Sie­gall. “All that to­geth­er re­al­ly is an ad­vance and doc­tors are thrilled when they can.”

“Some­times you see a ther­a­py add 8, 12 weeks in an end­point that’s not longterm sur­vival,” says the CEO. “It’s very ex­pen­sive and won’t nec­es­sar­i­ly change or cure an­oth­er seg­ment of the pop­u­la­tion and re­duce tox­i­c­i­ty, and there’s some push­back be­cause theres a ques­tion of the val­ue.”

That’s not the case here, he feels.

Lym­phoma ex­pert John Leonard, though, not­ed in a Tweet to me that there’s one fly in Seat­tle Ge­net­ics oint­ment.

As per the RATHL study 75% of pa­tients can drop Bleomycin af­ter cy­cle 2 AB­VD which dra­mat­i­cal­ly re­duces bleomycin tox­i­c­i­ty – so a big com­po­nent of this ar­gu­ment goes away

If so, physi­cians could be more like­ly to stick with the stan­dard,

An added ap­proval for Seat­tle Ge­net­ics is like­ly, nev­er­the­less. The FDA has made it abun­dant­ly clear that they want to see im­prove­ments in can­cer care, and is will­ing to move par­tic­u­lar­ly quick­ly for ap­proved ther­a­pies like Ad­cetris. And af­ter a fourth OK ear­li­er in the year, Seat­tle Ge­net­ics will be clos­er to the day when they can count Ad­cetris as a block­buster ther­a­py.

“We think there’s a strong val­ue propo­si­tion across the board,” he adds.”It is what pay­ers are cov­er­ing.”

George Yancopoulos (Regeneron)

Re­gen­eron co-founder George Yan­copou­los of­fers a com­bat­ive de­fense of the po­lice at a high school com­mence­ment. It didn’t go well

Typically, the commencement speech at Yorktown Central School District in Westchester — like most high schools — is an opportunity to encourage students to face the future with confidence and hope. Regeneron president and co-founder George Yancopoulos, though, went a different route.

In a fiery speech, the outspoken billionaire defended the police against the “prejudice and bias against law enforcement” that has erupted around the country in street protests from coast to coast. And for many who attended the commencement, Yancopoulos struck the wrong note at the wrong time, especially when he combatively challenged someone for interrupting his speech with a honk for “another act of cowardness.”

Elias Zer­houni dis­cuss­es ‘am­a­teur hour’ in DC, the de­struc­tion of in­fec­tious dis­ease R&D and how we need to prep for the next time

Elias Zerhouni favors blunt talk, and in a recent discussion with NPR, the ex-Sanofi R&D and ex-NIH chief had some tough points to make regarding the pandemic response.

Rather than interpret them, I thought it would be best to provide snippets straight from the interview.

On the Trump administration response:

It was basically amateur hour. There is no central concept of operations for preparedness, for pandemics, period. This administration doesn’t want to or has no concept of what it takes to protect the American people and the world because it is codependent. You can’t close your borders and say, “OK, we’re going to be safe.” You’re not going to be able to do that in this world. So it’s a lack of vision, basically just a lack of understanding, of what it takes to protect the American people.

Pfiz­er shares surge on pos­i­tive im­pact of their mR­NA Covid-19 vac­cine — part­nered with BioN­Tech — in an ear­ly-stage study

Pfizer and their partners at the mRNA specialist BioNTech have published the first glimpse of biomarker data from an early-stage study spotlighting the “robust immunogenicity” triggered by their Covid-19 vaccine, which is one of the leaders in the race to vanquish the global pandemic.

Researchers selected 45 healthy volunteers 18-55 years of age for the study. They were randomized to receive 2 doses, separated by 21 days, of 10 µg, 30 µg, or 100 µg of BNT162b1, “a lipid nanoparticle-formulated, nucleoside-modified, mRNA vaccine that encodes trimerized SARS-CoV-2 spike glycoprotein RBD.” Their responses were compared against the effect of a natural, presumably protective defense offered by a regular infection.

An ex­pe­ri­enced biotech is stitched to­geth­er from transpa­cif­ic parts, with 265 staffers and a fo­cus on ‘new bi­ol­o­gy’

Over the past few years, different teams at a pair of US-based biotechs and in labs in Japan have labored to piece together a group of cancer drug programs, sharing a single corporate umbrella with research colleagues in Japan. But now their far-flung operations have been knit together into a single unit, creating a pipeline with 10 cancer drug development programs — going from early-stage right into Phase III — and a host of discovery projects managed by a collective staff of some 265 people.

Sec­ond death trig­gers hold on Astel­las' $3B gene ther­a­py biotech's lead pro­gram, rais­ing fresh con­cerns about AAV

Seven months after Astellas shelled out $3 billion to acquire the gene therapy player Audentes, the biotech company’s lead program has been put on hold following the death of 2 patients taking a high dose of their treatment. And there was another serious adverse event recorded in the study as well, with a total of 3 “older” patients in the study affected.

The incidents are derailing plans to file for a near-term approval, which had been expected right about now.

Pos­i­tive Covid-19 vac­cine da­ta? New mouse study? OWS in­clu­sion? Yep, but some­how, the usu­al tid­bits from In­ovio back­fire

You don’t go more than 40 years in biotech without ever getting a product to market unless you can learn the art of writing a promotional press release. And Inovio captures the prize in baiting the hook.

Tuesday morning Inovio, which has been struggling to get its Covid-19 vaccine lined up for mass manufacturing, put out a release that touched on virtually every hot button in pandemic PR.

There was, first and foremost, an interim snapshot of efficacy from their Phase I program for INO-4800.

Seat­tle Ge­net­ics, Gen­mab turn on TV for a high­light reel in cer­vi­cal can­cer — but a ri­val biotech promis­es a bet­ter show

Seattle Genetics $SGEN and their partners at Genmab $GMAB polished up some positive Phase II numbers for their antibody drug conjugate tisotumab vedotin — you can call it TV — for recurrent cervical cancer. And while they mapped out a shortcut to a potential quick approval, the big challenge for this team is being presented by a rival biotech which muscled its way into the spotlight for the same indication a year ago.

Randy Schatzman, Bolt CEO (Bolt Biotherapeutics)

Bolt Bio­ther­a­peu­tics nabs $93.5M to push Provenge in­ven­tor's new idea deep­er in the clin­ic

A cancer-fighting concept from the inventor of the first cancer vaccine is nearing prime time, and its biotech developer has received a significant new infusion of cash to get it there.

Bolt Biotherapeutics announced a $93.5 million Series C round led by Sofinnova Investments and joined by more than 9 others, including Pfizer Ventures and RA Capital Management. That money will go toward pushing the San Francisco biotech’s platform of innate immune-boosting warheads through its first trial on metastatic solid tumors and into several more.

Days af­ter In­ter­cept re­jec­tion, Akero surges on ‘un­prece­dent­ed‘ NASH da­ta

A year and a half after scoring a $70 million Series B and a top Gilead executive as CEO, Akero Therapeutics has announced new data on their NASH drug. And with the field still reeling from a surprise FDA rejection this week, the news was enough to send their stock surging.

Akero had already said in March that its lead drug had beaten placebo in its Phase II trial, reducing liver fat by 14% in the highest dose group compared to 0.3% in placebo, according to MRI scans. But although NASH is an obesity-related condition and results from fatty buildup in the liver, the real immediate question for any therapy is whether it can resolve the fibrosis and inflammation that results from that buildup. Those data require biopsying the patients, a longer and more invasive process that was further complicated by a pandemic.
