Key blad­der can­cer da­ta pave way for Seat­tle Ge­net­ics to sub­mit mar­ket­ing ap­pli­ca­tion for armed an­ti­body

Seat­tle Ge­net­ics is one step clos­er to get­ting its sec­ond armed an­ti­body across the fin­ish line, af­ter the ‘break­through’ Astel­las-part­nered drug — en­for­tum­ab ve­dotin — helped pa­tients with ad­vanced or metasta­t­ic urothe­lial can­cer, whose dis­ease pro­gressed de­spite treat­ment with both plat­inum-con­tain­ing chemother­a­py and a check­point in­hibitor, in a key study.

The drug in­duced a 44% ob­jec­tive re­sponse rate (ORR) in 128 pa­tients — and al­though de­tailed re­sults from the sin­gle-arm EV-201 study will be re­vealed at a lat­er date, the da­ta are com­pelling enough for Seat­tle to sub­mit a US mar­ket­ing ap­pli­ca­tion for the an­ti­body drug con­ju­gate (ADC), the com­pa­ny said on Thurs­day. A late-stage tri­al de­signed to con­firm the drug’s safe­ty and ef­fi­ca­cy in this pa­tient pop­u­la­tion is on­go­ing.

AD­Cs are a class of ther­a­peu­tics in which a can­cer-killing tox­in is at­tached to a spe­cif­ic an­ti­body us­ing a biodegrad­able link­er. De­signed to min­i­mize the ef­fects of the chemother­a­py on healthy cells while max­i­miz­ing tu­mour cell death, the tech­nol­o­gy is some­times likened to a tro­jan horse as it is en­gi­neered to go un­no­ticed, de­liv­er­ing chemother­a­pies to cells ex­press­ing the anti­gen tar­get. Seat­tle Ge­net­ics $SGEN al­ready has one ADC on the mar­ket, Ad­cetris, and a slate of oth­ers in de­vel­op­ment.

En­for­tum­ab ve­dotin (EV) tar­gets Nectin-4, a cell ad­he­sion mol­e­cule iden­ti­fied as an ADC tar­get by Astel­las. The ex­per­i­men­tal ADC is al­so be­ing test­ed for use in new­ly di­ag­nosed pa­tients with lo­cal­ly ad­vanced or metasta­t­ic urothe­lial can­cer in com­bi­na­tion with Keytru­da and/or plat­inum chemother­a­py.

The drug con­tin­ues to be eval­u­at­ed in the two co­hort EV-201 tri­al: in pa­tients with lo­cal­ly ad­vanced or metasta­t­ic urothe­lial can­cer that have been pre­vi­ous­ly treat­ed with a PD-1 or PD-L1 in­hibitor, in­clud­ing those who have al­so been giv­en plat­inum-based chemother­a­py (co­hort 1); and those who have not re­ceived a plat­inum-con­tain­ing chemother­a­py and are in­el­i­gi­ble for the chemother­a­py cis­platin (co­hort 2).

In the pre­vi­ous phase I tri­al, EV gen­er­at­ed ORR of of 45%, with a me­di­an du­ra­tion of re­sponse (DOR) of 7.5 months in the check­point ex­pe­ri­enced pop­u­la­tion, SVB Leerink an­a­lyst An­drew Berens not­ed. “Based on the top-line da­ta an­nounced…we be­lieve that EV has suf­fi­cient­ly cleared the bar need­ed to ob­tain ac­cel­er­at­ed ap­proval, which we view as a 20-25% ORR with me­di­an DOR of ~5.5 months.”

Urothe­lial can­cer is the most com­mon type of blad­der can­cer. About 80,470 new cas­es of blad­der can­cer are ex­pect­ed to be di­ag­nosed this year, and it is an­tic­i­pat­ed 17,670 blad­der can­cer deaths will oc­cur in 2019, ac­cord­ing to Amer­i­can Can­cer So­ci­ety es­ti­mates. Da­ta sug­gest most pa­tients do not re­spond to check­point in­hibitors af­ter a plat­inum-con­tain­ing ther­a­py has failed as an ini­tial treat­ment for ad­vanced dis­ease, and there are no oth­er ap­proved op­tions for pa­tients once these two lines of treat­ment have been ex­haust­ed.

The DCT-OS: A Tech­nol­o­gy-first Op­er­at­ing Sys­tem - En­abling Clin­i­cal Tri­als

As technology-enabled clinical research becomes the new normal, an integrated decentralized clinical trial operating system can ensure quality, deliver consistency and improve the patient experience.

The increasing availability of COVID-19 vaccines has many of us looking forward to a time when everyday things return to a state of normal. Schools and teachers are returning to classrooms, offices and small businesses are reopening, and there’s a palpable sense of optimism that the often-awkward adjustments we’ve all made personally and professionally in the last year are behind us, never to return. In the world of clinical research, however, some pandemic-necessitated adjustments are proving to be more than emergency stopgap measures to ensure trial continuity — and numerous decentralized clinical trial (DCT) tools and methodologies employed within the last year are likely here to stay as part of biopharma’s new normal.

Gala­pa­gos chops in­to their pipeline, drop­ping core fields and re­or­ga­niz­ing R&D as the BD team hunts for some­thing 'trans­for­ma­tive'

Just 5 months after Gilead gutted its rich partnership with Galapagos following a bitter setback at the FDA, the Belgian biotech is hunkering down and chopping the pipeline in an effort to conserve cash while their BD team pursues a mission to find a “transformative” deal for the company.

The filgotinib disaster didn’t warrant a mention as Galapagos laid out its Darwinian restructuring plans. Forced to make choices, the company is ditching its IPF molecule ’1205, while moving ahead with a Phase II IPF study for its chitinase inhibitor ’4617.

Mod­er­na CEO brush­es off US sup­port for IP waiv­er, eyes more than $19B in Covid-19 vac­cine sales in 2021

Moderna is definitively more concerned with keeping pace with Pfizer in the race to vaccinate the world against Covid-19 than it is with Wednesday’s decision from the Biden administration to back an intellectual property waiver that aims to increase vaccine supplies worldwide.

In its first quarter earnings call on Thursday, Moderna CEO Stéphane Bancel shrugged off any suggestion that the newly US-backed intellectual property waiver would impact his company’s vaccine or bottom line. Still, the company’s stock price fell by about 9% in early morning trading.

'Chang­ing the whole game of drug dis­cov­ery': Leg­endary R&D vet Roger Perl­mut­ter leaps back in­to work as a biotech CEO

Roger Perlmutter needs no introduction to anyone remotely involved in biopharma. As the R&D chief first at Amgen and then Merck, he’s built a stellar reputation and a prolific career steering new drugs toward the market for everything from cancer to infectious diseases.

But for years, he’s also held a less known title: science partner at The Column Group, where he’s regularly consulted about the various ideas the VCs had for new startups.

Ad­comm splits slight­ly in fa­vor of FDA ap­prov­ing Chemo­Cen­tryx’s rare dis­ease drug

The FDA’s Arthritis Advisory Committee on Thursday voted 10 for and 8 against the approval of ChemoCentryx’s $CCXI investigational drug avacopan as a treatment for adults with a rare and serious disease known as anti-neutrophil cytoplasmic autoantibody (ANCA)-vasculitis.

The vote on whether the FDA should approve the drug was preceded by a split vote of 9 to 9 on whether the efficacy data support approval, and 10 to 8 that the safety profile of avacopan is adequate enough to support approval.

With no up­front pay­ment or mile­stones on the line, Nkar­ta and CRISPR join forces on CAR-NK search

Most deals in biotech come with hefty upfront payments attached, and the promise of big biobucks if a program works out. Not this one.

Nkarta has struck what CEO Paul Hastings calls a “real collaboration” with CRISPR Therapeutics to co-develop and commercialize two CAR-NK therapies, in addition to an NK+T program. The duo will split all R&D costs — and any worldwide profits — 50/50, Hastings said.

OcuWho? Star deal­mak­er turned aes­thet­ics czar Brent Saun­ders flips back in­to biotech. But who’s he team­ing up with now?

Brent Saunders went on a tear of headline-blazing deals building Allergan, merging and rearranging a variety of big companies into one before an M&A pact with Pfizer blew up and sent him on a bout of biotech drug deals. That didn’t work so well, so under pressure, he got his buyout at AbbVie — which needed a big franchise like Botox. And it was no big surprise to see him riding the SPAC wave into a recent $1 billion-plus deal that left him in the executive chairman’s seat at an aesthetics outfit — now redubbed The Beauty Health Company — holding a big chunk of the equity.

Drug pric­ing watch­dog joins the cho­rus of crit­ics on Bio­gen's ad­u­canum­ab: What about charg­ing $2,560 per year?

As if Biogen’s aducanumab isn’t controversial enough, the researchers at drug pricing watchdog ICER have drawn up the contours of a new debate: If the therapy does get approved for Alzheimer’s by June, what price should it command?

Their answer: At most $8,290 per year — and perhaps as little as $2,560.

Even at the top of the range, the proposed price is a fraction of the $50,000 that Wall Street has reportedly come to expect (although RBC analyst Brian Abrahams puts the consensus figure at $11.5K). With critics, including experts on the FDA’s advisory committee, making their fierce opposition to aducanumab’s approval loud and clear, the pricing pressure adds one extra wrinkle Biogen CEO Michel Vounatsos doesn’t need as he orders full-steam preparation for a launch.

Biden ad­min­is­tra­tion backs a po­lar­iz­ing pro­pos­al to waive IP for all Covid-19 vac­cines

In a surprise U-turn, the Biden administration said Wednesday that it will support a proposal at the World Trade Organization to temporarily waive intellectual property protections on Covid-19 vaccines.

The proposal, backed by South Africa and India at the WTO, seeks to help developing countries with limited vaccine supplies. The US and Europe historically opposed the proposal, saying IP should be protected because it incentivizes new drug and vaccine development.
