Bio­gen, Ab­b­Vie yank MS drug Zin­bry­ta off the mar­ket in the wake of en­cephali­tis cas­es

The mar­ket­ing ef­fort for the MS drug Zin­bry­ta (da­clizum­ab) im­plod­ed to­day af­ter Eu­ro­pean reg­u­la­tors flagged a lethal safe­ty warn­ing over cas­es of in­flam­ma­to­ry en­cephali­tis and menin­goen­cephali­tis. Bio­gen $BI­IB and Ab­b­Vie $AB­BV, which had been look­ing to spend this year build­ing sales of the MS treat­ment, are now yank­ing it off the mar­ket in the EU and the US.

“Giv­en the na­ture and com­plex­i­ty of ad­verse events be­ing re­port­ed, char­ac­ter­iz­ing the evolv­ing ben­e­fit/risk pro­file of Zin­bry­ta will not be pos­si­ble go­ing for­ward giv­en the lim­it­ed num­ber of pa­tients be­ing treat­ed,” the com­pa­nies said in a state­ment. “There­fore, Bio­gen and Ab­b­Vie be­lieve it is in the best in­ter­est of pa­tients to vol­un­tar­i­ly with­draw world­wide mar­ket­ing au­tho­riza­tions for Zin­bry­ta.”

En­cephali­tis is char­ac­ter­ized by brain in­flam­ma­tion, usu­al­ly caused by a vi­ral in­fec­tion, which is rare and po­ten­tial­ly dead­ly.

Al San­drock, Bio­gen

The drug hit the US mar­ket in 2016 with a black box warn­ing over the threat of liv­er tox­i­c­i­ty af­ter the FDA ap­proved it for third-line MS cas­es. Reg­u­la­tors, though, have been will­ing to put up with con­sid­er­able safe­ty prob­lems with MS drugs so long as the dam­age to pa­tients is rare and the ben­e­fits con­sid­er­able. In this case, Bio­gen and Ab­b­Vie have yet to gain much trac­tion for a drug that an­a­lysts had felt would be lim­it­ed to peak sales of $500 mil­lion a year.

The with­draw­al won’t have much im­pact on Ab­b­Vie longterm, where the R&D group is in hot pur­suit of sev­er­al po­ten­tial block­busters to bol­ster its work around Hu­mi­ra. Bio­gen, though, won’t get off so easy. The big biotech made its rep in MS and has a thin pipeline dom­i­nat­ed by a high-risk Alzheimer’s ther­a­py. Bio­gen CMO Al San­drock man­aged to rat­tle the mar­ket re­cent­ly with news that they were adding pa­tients to their piv­otal tri­al for the Alzheimer’s drug to ac­count for some vari­abil­i­ty in the da­ta — which in turn trig­gered fresh jit­ters over its fu­ture.

“Bio­gen be­lieves the vol­un­tary world­wide with­draw­al of ZIN­BRY­TA, a treat­ment for re­laps­ing mul­ti­ple scle­ro­sis, is in the best in­ter­est of pa­tients,” said San­drock in a state­ment. “Bio­gen and Ab­b­Vie con­tin­ue to pri­or­i­tize pa­tient safe­ty and the care of mul­ti­ple scle­ro­sis pa­tients world­wide.”

Pssst: That big Bio­haven Alzheimer's study? It was a bust. Even the sub­group analy­sis ex­ecs tout­ed was a flop

You know it’s bad when a biopharma player plucks out a subgroup analysis for a positive take — even though it was way off the statistical mark for success, like everything else.

So it was for Biohaven $BHVN on MLK Monday, as the biotech reported on the holiday that their Phase II/III Alzheimer’s study for troriluzole flunked both co-primary endpoints as well as a key biomarker analysis.

The drug — a revised version of the ALS drug riluzole designed to regulate glutamate — did not “statistically differentiate” from placebo on the Alzheimer’s Disease Assessment Scale-Cognitive Subscale 11 (ADAS-cog) and the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB).  The “hippocampal volume” assessment by MRI also failed to distinguish itself from placebo for all patients fitting the mild-to-moderate disease profile they had established for the study.

Poll: Should Joshua Sharf­stein or Janet Wood­cock lead the FDA from here?

It’s time for a new FDA commissioner to come on board, a rite of passage for Joe Biden’s administration that should help seal the new president’s rep on seeking out the experts to lead the government over the next 4 years.

As of now, the competition for the top job appears to have narrowed down to 2 people: The longtime CDER chief Janet Woodcock and Joshua Sharfstein, the former principal deputy at the FDA under Peggy Hamburg. Both were appointed by Barack Obama.

Eli Lil­ly tees up dis­cov­ery pact worth more than $1.6B with Merus for T cell-fo­cused bis­pe­cif­ic an­ti­bod­ies

Under science chief Dan Skovronsky, Eli Lilly has taken some big swings at next-gen therapies, including trying to find the next big thing in oncology. Now, after one early failure in the field, Lilly is going back to the bispecific antibody well with a new deal with a Dutch biotech.

Lilly will pay $40 million upfront with an additional $20 million equity stake in Merus NV to identify and develop three bispecific antibodies looking to engage the CD3 antigen on T cells and redirect immune cells, the Indianapolis pharma giant said Tuesday.

As coro­n­avirus vari­ants trig­ger new alarms, the NIH is putting an un­der-the-radar ‘next-gen’ vac­cine in­to PhI

Over the past year, the world has been transfixed by the development of new vaccines to fight SARS-CoV-2. In a frenzy of activity, the new mRNA approach has delivered pioneering emergency approvals in record time. And with some setbacks, the more traditional big players are coming along with added jabs as the most affluent nations in the world begin to vaccinate large portions of their populations.

The IPO queue adds 5 more biotechs hop­ing to ring in 2021 by blitz­ing Nas­daq

Following a record year for IPOs — in terms of both proceeds and count — there’s already a long lineup of biotechs ready to jump onto Nasdaq in the new year. The companies are likely looking for much higher raises than they initially projected on their S-1s. Now it’s time to see if investors are still hungry for another round of biotech stocks.

Sana helped set the pace early on, as its founders look to divvy up a fortune from their IPO. And late last week 5 more biotechs crowded in, looking to pick up the pace where 2020 left off. Here they are:

As­traZeneca keeps the ball rolling on Dai­ichi-part­nered En­her­tu, pick­ing up 2nd in­di­ca­tion in gas­tric can­cer

AstraZeneca’s big gamble on Daiichi Sankyo’s antibody-drug conjugate Enhertu has already paid off with a big approval in breast cancer more than a year ago. But the partners have big plans for their blockbuster in the making, and a new nod in gastric cancer will raise their spirits even higher.

The FDA on Friday approved Enhertu to treat locally advanced or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma in patients who have previously undergone at least one round of treatment with a Herceptin-based regimen, AstraZeneca said in a release.

Ox­ford gets £100M to seize a 'break­through mo­men­t' in fight­ing su­per­bugs

Close to 70 years after Oxford scientists purified penicillin and confirmed its effect as an antibacterial drug, the university is establishing a new research institute at the forefront of combating antimicrobial resistance.

The Ineos Oxford Institute for AMR Research will initially be powered by a $136 million (£100 million) donation from Ineos, the UK-based chemicals giant founded by billionaire Jim Ratcliffe, that also plays a hand in manufacturing medical and pharma products.
