#AS­CO17 high­lights: Roche ush­ers ear­ly-stage bis­pe­cif­ic in­to view; Agios, Cel­gene un­veil more AG-221 da­ta; Plen­ty more com­ing at AS­CO

Roche has an ear­ly-stage T cell bis­pe­cif­ic — which binds si­mul­ta­ne­ous­ly to T cells and tu­mor cells — called CEA-TCB (RO6958688; RG7802) that it is bull­ish about. It re­leased a very ear­ly look at Phase I da­ta for AS­CO, look­ing at monother­a­py as well as a com­bo with its check­point Tecen­triq. The da­ta demon­strate: “In the monother­a­py, out of 31 pa­tients with mCRC treat­ed with CEA-TCB dos­es of 60mg or above, 14 pa­tients (45%) showed ei­ther par­tial re­sponse (n=2, 6%) or sta­ble dis­ease (n=12, 39%). For the com­bi­na­tion, of 25 pa­tients treat­ed with dos­es of 5–160mg of CEA-TCB, 11 pa­tients with MSS mCRC were treat­ed at dos­es shown to in­duce tu­mour le­sion in­flam­ma­tion (80 and 160 mg). Nine of these pa­tients (82%) showed ei­ther a par­tial re­sponse (n=2, 18%) or sta­ble dis­ease (n=7, 64%) in this dif­fi­cult-to-treat pop­u­la­tion.”

Agios and Cel­gene delve deep­er in­to AG-221 da­ta

Agios and its big part­ner Cel­gene have al­ready filed for an ap­proval of AG-221, which they now pre­fer to call enasi­denib. Pre­sum­ably we’ll get a bet­ter look at its da­ta — and its prospects — at the con­fer­ence. In the mean­time it of­fers an up­date on their Phase I dose es­ca­la­tion study:

For R/R AML pts, over­all re­sponse rate (ORR) was 40.3%, in­clud­ing 34 (19.3%) com­plete re­mis­sions (CR; Table). Re­sponse was as­so­ci­at­ed with cel­lu­lar dif­fer­en­ti­a­tion, typ­i­cal­ly with no ev­i­dence of apla­sia. Me­di­an over­all sur­vival (OS) for R/R AML pts was 9.3 months (mos). For pts who at­tained CR, OS was 19.7 mos. Pts who had re­ceived ≥2 pri­or AML reg­i­mens (n=94; 53%) had me­di­an OS of 8.0 mos.

So far, so good.

A snap­shot of Five Prime’s cabi­ral­izum­ab da­ta

Michael Schmidt at Leerink of­fered this quick look at Phase I/II da­ta from Five Prime’s cabi­ral­izum­ab. He not­ed:

Re­call, this study ad­vanced in­to Phase II in May 2016 and in April 2017 en­roll­ment of 30 PVNS pa­tients com­plet­ed. Ab­stract #11078 high­lights ac­tiv­i­ty at the 4mg/kg dose (that was cho­sen for Phase II) with 1 par­tial re­sponse (PR) seen in 3 pa­tients in the Phase I por­tion of the study. One pa­tient dis­con­tin­ued based on tri­al rues fol­low­ing cre­a­tine ki­nase (CK) el­e­va­tion, an asymp­to­matic lab­o­ra­to­ry anom­aly and on-tar­get ef­fect of macrophage in­hi­bi­tion. In the Phase II por­tion, FPRX re­port­ed 4 PRs in 7 evalu­able pa­tients. An­oth­er 6 pa­tients in the Phase II por­tion have re­ceived treat­ment but were not evalu­able at time of ab­stract sub­mis­sion. Pos­i­tive func­tion­al sta­tus im­prove­ments were al­so not­ed in ob­jec­tive re­spon­ders. Man­age­ment pre­vi­ous­ly em­pha­sized the im­por­tance of qual­i­ty of life and func­tion im­prove­ments (e.g., pain) for PVNS pa­tients.

The good stuff is be­ing held back for AS­CO

You’re go­ing to have to wait for AS­CO for a lot of things, in­clud­ing more ma­ture da­ta on blue­bird bio’s an­ti-BC­MA CAR-T bb2121 Phase I re­lapsed/re­frac­to­ry mul­ti­ple myelo­ma study.

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.

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.

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.

Arde­lyx bags its first FDA OK for IBS, set­ting up a show­down with Al­ler­gan, Iron­wood

In the first of what it hopes will be a couple of major regulatory milestones for its new drug, Ardelyx has bagged an FDA approval to market Ibsrela (tenapanor) for irritable bowel syndrome.

The drug’s first application will be for IBS with constipation (IBS-C), inhibiting sodium-hydrogen exchanger NHE3 in the GI tract in such a way as to increase bowel movements and decrease abdominal pain. This comes on the heels of two successful Phase III trials.
