Agenus’ lead can­cer vac­cine flops, in­ves­ti­ga­tors read last rites over glioblas­toma PhII

Just days af­ter hand­ing over the reins on a big an­ti­body col­lab­o­ra­tion to In­cyte, Agenus is now slam­ming the brakes on its top can­cer vac­cine tri­al, con­ced­ing a flop.

The Lex­ing­ton, MA-based biotech $AGEN says an in­de­pen­dent da­ta mon­i­tor­ing com­mit­tee over­see­ing the Phase II com­bi­na­tion study of its can­cer vac­cine Prophage with Avastin (be­va­cizum­ab) found no en­cour­age­ment that the vac­cine — made of heat shock pro­tein-pep­tide com­plex­es tak­en from a pa­tient’s tu­mor tis­sue — was any bet­ter than be­va­cizum­ab alone in pro­long­ing sur­vival among brain can­cer pa­tients.

The study was launched in 2013 and in­tend­ed to re­cruit 165 pa­tients. Agenus qui­et­ly not­ed the fail­ure in a fil­ing with the SEC on Tues­day.

The bot­tom line in the 8-K:

The in­ter­im analy­sis sug­gest­ed that the tri­al is un­like­ly to demon­strate that the vac­cine in com­bi­na­tion with be­va­cizum­ab will lead to a bet­ter sur­vival than be­va­cizum­ab as a monother­a­py. There­fore, up­on the DSMB’s rec­om­men­da­tion, the ac­cru­al for the tri­al has been closed.

The biotech’s shares were down 5.5% in pre­mar­ket trad­ing Wednes­day.

A spokesper­son for the biotech says that while that Phase II has been closed, the pro­gram for Prophage is def­i­nite­ly con­tin­u­ing. Just a few weeks ago Agenus an­nounced plans to com­bine Prophage and the PD-1 drug Keytru­da in a new tri­al. The failed study was in late-stage pa­tients and this next study will be for new­ly di­ag­nosed glioblas­toma pa­tients.

“The ra­tio­nale for syn­er­gy be­tween Prophage and a check­point in­hibitor is much greater,” she adds. “This, along with ear­li­er stage pa­tients be­ing stud­ied in the tri­al, leads to ex­pec­ta­tions of bet­ter out­comes.”

Like a long line­up of can­cer vac­cines in re­cent years, Agenus’ at­tempt to kick­start an im­mune sys­tem at­tack ap­peared safe but in­ef­fec­tive in the most re­cent set­back, too weak to make a sig­nif­i­cant dif­fer­ence. The biotech al­so has a slate of check­points in the clin­ic, look­ing to fol­low up on a new ap­proach to re­mov­ing can­cer cells’ nat­ur­al de­fens­es so that they can be elim­i­nat­ed by the im­mune sys­tem.

A few days ago Agenus backed away from a 50/50 deal split arrange­ment that it had with In­cyte on an­ti­body de­vel­op­ment, trig­ger­ing some spec­u­la­tion that the com­pa­ny was too weak fi­nan­cial­ly to keep up its end of the bar­gain. Agenus set­tled for an $80 mil­lion cash in­fu­sion and a roy­al­ty stream on any prod­ucts that hit the mar­ket.

It’s fi­nal­ly over: Bio­gen, Ei­sai scrap big Alzheimer’s PhI­I­Is af­ter a pre­dictable BACE cat­a­stro­phe rais­es safe­ty fears

Months after analysts and investors called on Biogen and Eisai to scrap their BACE drug for Alzheimer’s and move on in the wake of a string of late-stage failures and rising safety fears, the partners have called it quits. And they said they were dropping the drug — elenbecestat — after the independent monitoring board raised concerns about…safety.

We don’t know exactly what researchers found in this latest catastrophe, but the companies noted in their release that investigators had determined that the drug was flunking the risk/benefit analysis.

It's not per­fect, but it's a good start: FDA pan­elists large­ly en­dorse Aim­mune's peanut al­ler­gy ther­a­py

Two days after a fairly benign review from FDA staff, an independent panel of experts largely endorsed the efficacy and safety of Aimmune’s peanut allergy therapy, laying the groundwork for approval with a risk evaluation and mitigation strategy (REMS).

Traditionally, peanut allergies are managed by avoidance, but the threat of accidental exposure cannot be nullified. Some allergists have devised a way to dose patients off-label with peanut protein derived from supermarket products to wean them off their allergies. But the idea behind Aimmune’s product was to standardize the peanut protein, and track the process of desensitization — so when accidental exposure in the real world invariably occurs, patients are less likely to experience a life-threatening allergic reaction.

Rit­ter bombs fi­nal PhI­II for sole lac­tose in­tol­er­ance drug — shares plum­met

More than two years ago Ritter Pharmaceuticals managed to find enough silver lining in its Phase IIb/III study — after missing the top-line mark — to propel its lactose intolerance toward a confirmatory trial. But as it turned out, the enthusiasm only set the biotech and its investors up to be sorely disappointed.

This time around there’s little left to salvage. Not only did RP-G28 fail to beat placebo in reducing lactose intolerance symptoms, patients in the treatment group actually averaged a smaller improvement. On a composite score measuring symptoms like abdominal pain, cramping, bloating and gas, patients given the drug had a mean reduction of 3.159 while the placebo cohort saw a 3.420 drop on average (one-sided p-value = 0.0106).

Ear­ly snap­shot of Ad­verum's eye gene ther­a­py sparks con­cern about vi­sion loss

An early-stage update on Adverum Biotechnologies’ intravitreal gene therapy has triggered investor concern, after patients with wet age-related macular degeneration (AMD) saw their vision deteriorate, despite signs that the treatment is improving retinal anatomy.

Adverum, on Wednesday, unveiled 24-week data from the OPTIC trial of its experimental therapy, ADVM-022, in six patients who have been administered with one dose of the therapy. On average, patients in the trial had severe disease with an average of 6.2 anti-VEGF injections in the eight months prior to screening and an average annualized injection frequency of 9.3 injections.

Alex Ar­faei trades his an­a­lyst's post for a new role as biotech VC; Sanofi vet heads to Vi­for

Too often, Alex Arfaei arrived too late. 

An analyst at BMO Capital Markets, he’d meet with biotech or pharmaceutical heads for their IPO or secondary funding and his brain, trained on a biology degree and six years at Merck and Endo, would spring with questions: Why this biomarker? Why this design? Why not this endpoint? Not that he could do anything about it. These execs were coming for clinical money; their decisions had been made and finalized long ago.

Lisa M. DeAngelis, MSKCC

MSK picks brain can­cer ex­pert Lisa DeAn­ge­lis as its next CMO — fol­low­ing José Basel­ga’s con­tro­ver­sial ex­it

It’s official. Memorial Sloan Kettering has picked a brain cancer expert as its new physician-in-chief and CMO, replacing José Baselga, who left under a cloud after being singled out by The New York Times and ProPublica for failing to properly air his lucrative industry ties.

His replacement, who now will be in charge of MSK’s cutting-edge research work as well as the cancer care delivered by hundreds of practitioners, is Lisa M. DeAngelis. DeAngelis had been chair of the neurology department and co-founder of MSK’s brain tumor center and was moved in to the acting CMO role in the wake of Baselga’s departure.

Tal Zaks. Moderna

The mR­NA uni­corn Mod­er­na has more ear­ly-stage hu­man da­ta it wants to show off — reach­ing new peaks in prov­ing the po­ten­tial

The whole messenger RNA field has attracted billions of dollars in public and private investor cash gambled on the prospect of getting in on the ground floor. And this morning Boston-based Moderna, one of the leaders in the field, wants to show off a few more of the cards it has to play to prove to you that they’re really in the game.

The whole hand, of course, has yet to be dealt. And there’s no telling who gets to walk with a share of the pot. But any cards on display at this point — especially after being accused of keeping its deck under lock and key — will attract plenty of attention from some very wary, and wired, observers.

“In terms of the complexity and unmet need,” says Tal Zaks, the chief medical officer, “this is peak for what we’ve accomplished.”

Moderna has two Phase I studies it wants to talk about now.

Sanofi takes a $260M hit to ex­tri­cate it­self from a dis­as­trous al­liance with Lex­i­con

Sanofi spent $300 million in cash to get into a $1.7 billion alliance with Lexicon on their SGLT1/2 diabetes drug sotagliflozin. And now that the drug has been spurned by the FDA after burning through a program that provided mixed late-stage data and a late shot at a last-place finish, the French pharma giant is forking over another $260 million to get out of the deal.

Sanofi’s unhappiness was already apparent when the company — now under new CEO Paul Hudson — posted a statement back in July that they were dropping the deal. But it wasn’t that simple.
