Zaf­gen's sec­ond try at Prad­er-Willi syn­drome trig­gers an­oth­er safe­ty alarm in pre­clin­i­cal tox study

Zaf­gen’s $ZFGN lat­est shot at cre­at­ing the first ther­a­py to treat pa­tients with rare cas­es of obe­si­ty brought on by Prad­er-Willi syn­drome has hit a safe­ty alarm be­fore the drug even man­aged to make it in­to the clin­ic.

The suc­ces­sor to be­lo­ranib — which blew up with spec­tac­u­lar ef­fect sev­er­al years ago fol­low­ing a clin­i­cal hold by the FDA — ZGN-1258 was sup­posed to be the biotech’s come­back drug in the field. In­stead, the biotech re­port­ed af­ter the mar­ket closed on Mon­day that it is sus­pend­ing plans for an IND af­ter re­searchers tracked mus­cle de­te­ri­o­ra­tion in a ro­dent mod­el of the dis­ease.

Zaf­gen’s stock shriv­eled at the men­tion of a new safe­ty alert. The shares plum­met­ed 35% af­ter the bell.

From their state­ment to­day:

Non­clin­i­cal da­ta showed de­gen­er­a­tion and oth­er anom­alies in rat mus­cle tis­sue to dif­fer­ent de­grees in both ve­hi­cle and dose arms of the stud­ies. The ef­fects were ab­sent from oth­er an­i­mal species in long term mod­els, and im­por­tant­ly, this find­ing has not been ob­served in any of the Com­pa­ny’s oth­er MetAP2 in­hibitors or clin­i­cal tri­als and ap­pears to be spe­cif­ic to ZGN-1258. Zaf­gen will pro­vide an up­date on plans for ZGN-1258 at a lat­er time, if war­rant­ed, fol­low­ing fur­ther eval­u­a­tion.

The move to shelve the IND came af­ter Zaf­gen re­port­ed in an SEC fil­ing late last year that every­thing had been lined up to ini­ti­ate clin­i­cal tri­als ex­cept for 1 last pre­clin­i­cal tri­al, which had to be re­done by a new CRO af­ter the first CRO had con­duct­ed it “im­prop­er­ly.”

Any fresh hint of a safe­ty warn­ing is tox­ic to Zaf­gen, which had to re­or­ga­nize and ul­ti­mate­ly re­place the se­nior ex­ecs who went on to oth­er en­deav­ors af­ter the first big crash. The biotech re­cent­ly re­port­ed what it called en­cour­ag­ing ear­ly da­ta about their lead drug, ZGN-1061 for obe­si­ty re­lat­ed to di­a­betes. Re­searchers re­port­ed pos­i­tive im­prove­ments in weight loss and blood sug­ar lev­els for di­a­bet­ics.

The lead drug, though, has al­so been un­der a cloud since the FDA dropped a clin­i­cal hold on the pro­gram last No­vem­ber, cit­ing CV safe­ty con­cerns. Leerink’s Joseph Schwartz has re­mained fo­cused on a key bio­mark­er for CV risk, even as the com­pa­ny pur­sued a risky ex-US tri­al.

Di­a­betes is a field with a huge pa­tient pop­u­la­tion, and even a hint of a safe­ty is­sue could prove lethal for any drug in de­vel­op­ment for this group.

And obe­si­ty drugs in gen­er­al are al­ways un­der a mi­cro­scope at the FDA, even af­ter the lat­est gen­er­a­tion hit the mar­ket, though they proved dra­mat­i­cal­ly un­suc­cess­ful as a com­mer­cial prod­uct.

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.

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.

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.

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.

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.

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.”
