Phase III read­outs spell dis­as­ter for Genen­tech’s lead IBD drug

Roche had big plans for etrolizum­ab. Eye­ing a hy­per-com­pet­i­tive IBD and Crohn’s mar­ket where they have not his­tor­i­cal­ly been a play­er, the com­pa­ny rolled out 8 dif­fer­ent Phase III tri­als, test­ing the an­ti­body for two dif­fer­ent us­es across a range of dif­fer­ent pa­tient groups.

On Mon­day, Roche re­leased re­sults for 4 of those stud­ies, and they mark a de­cid­ed set­back for both the Swiss phar­ma and their biotech sub Genen­tech, po­ten­tial­ly spelling an end to a drug they put over half-a-decade and mil­lions of dol­lars be­hind.

The four stud­ies ex­am­ined etrolizum­ab as a treat­ment for ul­cer­a­tive col­i­tis, test­ing to see if it worked as an in­duc­tion treat­ment for pa­tients who had nev­er had an­ti-TNF ther­a­py (i.e. the mega-block­buster Hu­mi­ra); if it worked as a main­te­nance ther­a­py for peo­ple who had nev­er tak­en an­ti-TNF drugs; and if it worked as both an in­duc­tion and a main­te­nance ther­a­py for pa­tients who had pre­vi­ous­ly tak­en an­ti-TNF drugs.

In one 358-per­son tri­al of pa­tients who had nev­er tak­en an­ti-TNF drugs, etrolizum­ab was bet­ter than place­bo at in­duc­ing re­mis­sion. But in the sec­ond 358-per­son tri­al test­ing the same thing, it wasn’t. In the study that test­ed etrolizum­ab as a main­te­nance ther­a­py, the ex­per­i­men­tal drug proved no bet­ter than place­bo. And in the study that test­ed etrolizum­ab as a main­te­nance and in­duc­tion ther­a­py, etrolizum­ab was bet­ter than place­bo at in­duc­ing re­mis­sion but no bet­ter at sus­tain­ing re­mis­sion.

The re­sult was a hodge­podge of sta­tis­tics that ex­ec­u­tives could on­ly de­scribe as dis­ap­point­ing.

“We are dis­ap­point­ed with these re­sults, be­cause we know that peo­ple with ul­cer­a­tive col­i­tis need new treat­ment op­tions,” CMO Levi Gar­raway said in a state­ment.

Genen­tech did not re­lease the topline da­ta, but said they will do so at fu­ture med­ical con­fer­ences. The safe­ty re­sults were con­sis­tent with pre­vi­ous stud­ies, the com­pa­ny said.

The re­sults won’t end the late-stage IBD pro­gram, even as it sets it back con­sid­er­ably. In ad­di­tion to open-la­bel ex­pan­sion stud­ies, the com­pa­ny is still run­ning a pair of Phase III tri­als in Crohn’s dis­ease.

Be­hind etrolizum­ab, Genen­tech has one oth­er mid-stage as­set for in­flam­ma­to­ry dis­eases: An IL-22 fu­sion pro­tein now in Phase II for IBD. By con­trast, etrolizum­ab works as an in­te­grin in­hibitor sim­i­lar to Take­da’s En­tyvio.

The mixed bag is the sec­ond set­back for Genen­tech in the past week, af­ter the com­pa­ny’s check­point in­hibitor Tecen­triq failed in a triple-neg­a­tive breast can­cer study on Fri­day.

With ad­u­canum­ab caught on a cliff, Bio­gen’s Michel Vounatsos bets bil­lions on an­oth­er high-risk neu­ro play

With its FDA pitch on the Alzheimer’s drug aducanumab hanging perilously close to disaster, Biogen is rolling the dice on a $3.1 billion deal that brings in commercial rights to one of the other spotlight neuro drugs in late-stage development — after it already failed its first Phase III.

The big biotech has turned to Sage Therapeutics for its latest deal, close to a year after the crushing failure of Sage-217, now dubbed zuranolone, in the MOUNTAIN study.

As­traZeneca, Ox­ford on the de­fen­sive as skep­tics dis­miss 70% av­er­age ef­fi­ca­cy for Covid-19 vac­cine

On the third straight Monday that the world wakes up to positive vaccine news, AstraZeneca and Oxford are declaring a new Phase III milestone in the fight against the pandemic. Not everyone is convinced they will play a big part, though.

With an average efficacy of 70%, the headline number struck analysts as less impressive than the 95% and 94.5% protection that Pfizer/BioNTech and Moderna have boasted in the past two weeks, respectively. But the British partners say they have several other bright spots going for their candidate. One of the two dosing regimens tested in Phase III showed a better profile, bringing efficacy up to 90%; the adenovirus vector-based vaccine requires minimal refrigeration, which may mean easier distribution; and AstraZeneca has pledged to sell it at a fraction of the price that the other two vaccine developers are charging.

TCR pi­o­neer Im­muno­core scores a first with a land­mark PhI­II snap­shot on over­all sur­vival for a rare melanoma

Bahija Jallal’s crew at TCR pioneer Immunocore says they have nailed down a promising set of pivotal data for their lead drug in a frontline setting for a solid tumor. And they are framing this early interim readout as the convincing snapshot they need to prove that their platform can deliver on a string of breakthrough therapies now in the clinic or planned for it.

In advance of the Monday announcement, Jallal and R&D chief David Berman took some time to walk me through the first round of Phase III data for their lead TCR designed to treat rare, frontline cases of metastatic uveal melanoma that come with a grim set of survival expectations.

Af­ter Ko­dak de­ba­cle, US lends $1.1B to a syn­thet­ic bi­ol­o­gy com­pa­ny and their big Covid-19, mR­NA plans

In mid-August, as Kodak’s $765 million government-backed push into drug manufacturing slowly fell apart in national headlines, Ginkgo Bioworks CEO Jason Kelly got a message from his company’s government liaison: HHS wanted to know if they, too, might want a loan.

The government’s decision to lend Kodak three quarters of a billion dollars raised eyebrows because Kodak had never made drugs before. But Ginkgo, while not a manufacturing company, had spent the last decade refining new ways to produce materials inside cells and building automated facilities across Boston.

Urovan­t's lead drug dis­ap­points in mid-stage study as first big FDA de­ci­sion looms

Just as Urovant gets ready for its first big FDA decision on vibegron, the drug has flopped in what would’ve been a follow-on indication.

In a Phase IIa trial involving women with abdominal pain due to irritable bowel syndrome, vibegron failed to meet the bar on improving “average worst abdominal pain” over 12 weeks, compared to placebo, among IBS-D patients.

There were actually slightly more responders in the placebo group than in the drug arm, with only 40.9% of those randomized to vigebron achieving at least a 30% decrease in “worst abdominal pain” in the past 24 hours. The trial enrolled 222 women but only 189 completed the study.

Gen­mab ax­es an ADC de­vel­op­ment pro­gram af­ter the da­ta fail to im­press

Genmab $GMAB has opted to ax one of its antibody-drug conjugates after watching it flop in the clinic.

The Danish biotech reported Tuesday that it decided to kill their program for enapotamab vedotin after the data gathered from expansion cohorts failed to measure up. According to the company:

While enapotamab vedotin has shown some evidence of clinical activity, this was not optimized by different dose schedules and/or predictive biomarkers. Accordingly, the data from the expansion cohorts did not meet Genmab’s stringent criteria for proof-of-concept.

Vas Narasimhan's 'Wild Card' drugs: No­var­tis CEO high­lights po­ten­tial jack­pots, as well as late-stage stars, in R&D pre­sen­ta­tion

Novartis is always one of the industry’s biggest R&D spenders. As they often do toward the end of each year, company execs are highlighting the drugs they expect will most likely be winners in 2021.

And they’re also dreaming about some potential big-time lottery tickets.

As part of its annual investor presentation Tuesday, where the company allows investors and analysts to virtually schmooze with the bigwigs, Novartis CEO Vas Narasimhan will outline what he thinks are the pharma’s “Wild Cards.” The slate of five experimental drugs are those that Novartis hopes can be high-risk, high-reward entrants into the market over the next half-decade or so, and cover a wide range of indications.

The ad­u­canum­ab co­nun­drum: The PhI­II failed a clear reg­u­la­to­ry stan­dard, but no one is cer­tain what that means any­more at the FDA

Eighteen days ago, virtually all of the outside experts on an FDA adcomm got together to mug the agency’s Billy Dunn and the Biogen team when they presented their upbeat assessment on aducanumab. But here we are, more than 2 weeks later, and the ongoing debate over that Alzheimer’s drug’s fate continues unabated.

Instead of simply ruling out any chance of an approval, the logical conclusion based on what we heard during that session, a series of questionable approvals that preceded the controversy over the agency’s recent EUA decisions has come back to haunt the FDA, where the power of precedent is leaving an opening some experts believe can still be exploited by the big biotech.

Al­ny­lam gets the green light from the FDA for drug #3 — and CEO John Maraganore is ready to roll

Score another early win at the FDA for Alnylam.

The FDA put out word today that the agency has approved its third drug, lumasiran, for primary hyperoxaluria type 1, better known as PH1. The news comes just 4 days after the European Commission took the lead in offering a green light.

An ultra rare genetic condition, Alnylam CEO John Maraganore says there are only some 1,000 to 1,700 patients in the US and Europe at any particular point. The patients, mostly kids, suffer from an overproduction of oxalate in the liver that spurs the development of kidney stones, right through to end stage kidney disease.
