Seat­tle Ge­net­ics/Astel­las win pri­or­i­ty US re­view for armed an­ti­body aimed at blad­der can­cer

Seat­tle Ge­net­ics has se­cured a speedy re­view of its sec­ond armed an­ti­body, cour­tesy of the FDA.

The com­pa­ny’s ‘break­through’ Astel­las-part­nered drug — en­for­tum­ab ve­dotin — has pro­cured pri­or­i­ty re­view from the US reg­u­la­tor, af­ter da­ta showed it helped pa­tients with a stub­born type of blad­der can­cer.

The drug-in­duced a 44% ob­jec­tive re­sponse rate (ORR) in 128 pa­tients whose dis­ease had pro­gressed de­spite treat­ment with both plat­inum-con­tain­ing chemother­a­py and a check­point in­hibitor in the one-arm EV-201 study. About 12% of the pa­tients ex­pe­ri­enced a com­plete re­sponse, Seat­tle Ge­net­ics dis­closed at AS­CO this June.

A mar­ket­ing ap­pli­ca­tion for the drug has al­ready been sub­mit­ted — and a late-stage tri­al de­signed to con­firm the drug’s safe­ty and ef­fi­ca­cy in this pa­tient pop­u­la­tion is on­go­ing.

The FDA is ex­pect­ed to make its de­ci­sion on the drug by March 15, the com­pa­ny said on Mon­day. In a note pub­lished in Ju­ly, Stifel an­a­lysts es­ti­mat­ed that en­for­tum­ab ve­dotin will gen­er­ate North Amer­i­ca sales of about $367 mil­lion in 2024.

The part­ners are test­ing the drug in com­bi­na­tion with Mer­ck’s $MRK Keytru­da and with chemother­a­py, and as part of a triplet com­bo. The idea is to al­so push for ap­proval in the front­line set­ting and gen­er­ate block­buster sales, Seat­tle Ge­net­ics’ chief Clay Sie­gall told End­points News at AS­CO.

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 tu­mor 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 seen in a range of sol­id tu­mors.

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 that 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.

What con­tro­ver­sy? Eli Lil­ly plots Alzheimer's BLA fil­ing lat­er this year as FDA taps more an­ti-amy­loid drugs as break­throughs

The FDA is keeping the good news coming for Alzheimer’s drug developers. And Eli Lilly is taking them up on it.

Amid continued controversy around whether Biogen’s new flagship drug, Aduhelm, should have been approved at all — and swelling, heated debates surrounding its $56,000 price tag — the agency had no issue handing them and their Japanese partner Eisai a breakthrough therapy designation for a second anti-amyloid beta antibody, lecanemab, late Wednesday.

New FDA doc­u­ments show in­ter­nal dis­sent on Aduhelm ap­proval

In a lengthy review document and a pair of memos from top officials, the FDA released on Tuesday night its most detailed argument yet for approving Biogen’s intensely controversial Alzheimer’s drug aducanumab.

The documents amount to an agency attempt to quench the firestorm their decision kindled, as outside advisors members resigned and experts warned that an unproven drug now could stretch Medicare’s budget to a breaking point. Ultimately, the documents show how CDER director Patrizia Cavazzoni and Office of New Drugs director Peter Stein both concurred with FDA neuroscience head Billy Dunn on the accelerated approval while the staff at FDA’s Office of Biostatistics did not think an approval was warranted.

ODAC echoes FDA con­cern over In­cyte PD-1, as Paz­dur sig­nals broad­er shift for ac­cel­er­at­ed ap­proval

After the FDA lambasted their PD-1 ahead of an adcomm earlier this week, Incyte ran into new trouble Thursday as ODAC panelists voted against an accelerated OK by a wide margin.

Members of the Oncologic Drugs Advisory Committee recommended with a 13-4 vote to defer a regulatory decision on Incyte’s retifanlimab until after more data can be collected from a placebo-controlled trial. The PD-1 therapy is due for a PDUFA date in late July after receiving priority review earlier this year.

FDA en­cour­ages in­clud­ing in­cur­able can­cer pa­tients in tri­als, re­gard­less of pri­or ther­a­pies

The FDA on Thursday called to include those with incurable cancers (when there is no potential for cure or for prolonged/near normal survival) in appropriate clinical trials, regardless of whether they have received existing alternative treatments.

Historically, many cancer clinical trials have required that participating patients previously received multiple therapies, according to Richard Pazdur, director of the FDA’s Oncology Center of Excellence.

Sen­a­tors call for hear­ing to ex­am­ine how Medicare will han­dle Bio­gen's new Alzheimer's drug

Two top Senate Finance committee senators on Thursday called for a hearing to examine the questions and challenges for Medicare arising from the FDA’s recent approval of Biogen’s Aduhelm, the controversial new drug approved to treat Alzheimer’s disease.

In a letter to Senate Finance chair Ron Wyden (D-OR) and ranking member Mike Crapo (R-ID), subcommittee chair Elizabeth Warren (D-MA) and Bill Cassidy (R-LA) hinted at making policy changes to enable Medicare to more directly connect prescription drug pricing to clinical effectiveness. They raised questions about the “dramatic implications for our health care system” from the approval, which they said “stretch well beyond the scope of FDA’s jurisdiction.”

Karen Flynn, Catalent

Q&A: When the pan­dem­ic struck, Catal­en­t's CCO had just joined the team

Karen Flynn came aboard Catalent’s team just in time.

The company was going through a surge of changes, and she had been brought over from her role as CCO of West Pharmaceutical Services to serve in the same capacity for the New Jersey-based CDMO. Then a few months later, the pandemic was in full-force.

Since then, Catalent’s been in hyper-expansion mode. In early May, it acquired Promethera’s Hepatic Cell Therapy Support SA subsidiary and its 32,40-square-foot facility in Gosselies, Belgium. Prior to that, the company acquired Belgian CDMO Delphi Genetics, wrapped up the expansion of an already-existing site in Madison, WI and added an ultra-low temperature freezer partner in Sterling. As Emergent has botched millions of doses of AstraZeneca’s vaccine, the company has swooped in to move that production to its Maryland plant as well.

An­oth­er Cor­bus pro­gram hits the skids af­ter late-stage flop, plum­met­ing the small biotech's shares

Corbus Pharmaceuticals’ plans to position lenabasum as a pipeline-in-a-product aren’t going so well.

After shelving a program in scleroderma, the Norwood, MA-based biotech has revealed that its lead candidate failed both the primary and secondary endpoints in another Phase III trial.

Lenabasum failed to show a statistically significant difference in total improvement compared with placebo in treating dermatomyositis, a rare disease that causes muscle inflammation and skin rash, the company said Thursday. The news sent Corbus’ $CRBP stock spiraling around 30% early Thursday morning.

On heels of Aduhelm ap­proval, Bris­tol My­ers jumps back in­to Alzheimer's race

Bristol Myers Squibb last put major resources behind an Alzheimer’s drug nearly a decade ago, when their own attempt at targeting amyloid flamed out in mid-stage studies. They invented another molecule, a Tau-targeted antibody, but jettisoned it to Biogen in 2017 as they dropped out of neuroscience altogether.

But on Thursday, the New York pharma announced they were getting back in the game. Bristol Myers exercised an $80 million option to bring a tau-targeted antibody from Prothena into a Phase I study. The opt-in, which Bristol Myers triggered ahead of analyst expectations, opens the door for another $1.7 billion in milestones down the road.
