In­cyte flips Chi­na rights of Macro­Gen­ic­s' PD-1 to an am­bi­tious Zai Lab keen on leapfrog­ging pi­o­neers with com­bos

Amid the pro­lif­er­a­tion of check­point in­hibitors in Chi­na, Zai Lab is bring­ing in one more PD-1 agent in a move to in­stall what has be­come an es­sen­tial part of any im­muno-on­col­o­gy pipeline.

Orig­i­nal­ly de­vel­oped by Macro­Gen­ics and now con­trolled by In­cyte, IN­CM­GA0012 is in Zai Lab’s view a glob­al­ly com­pet­i­tive as­set that can stand as both a monother­a­py and com­bi­na­tion in­gre­di­ent.

“The mol­e­c­u­lar pro­file is quite sim­i­lar to Keytru­da and Op­di­vo,” said Yongjiang Hei, Zai Lab’s CSO in on­col­o­gy, on an in­vestor call.

The first com­bo Zai Lab plans to test will fea­ture mar­ge­tux­imab — a HER2 tar­get­ing drug in-li­censed from Macro­Gen­ics for $25 mil­lion up­front. Hav­ing Chi­na rights to both as­sets will al­low for smoother co­or­di­na­tion in glob­al and Chi­na stud­ies, the com­pa­ny added.

Oth­er pos­si­ble com­bos in­volve Ze­ju­la, the PARP in­hibitor from GSK’s Tesaro, in women’s can­cer as well as lung and brain can­cer. Zai Lab is al­so keen about com­bin­ing a PD-1 with the switch ki­nase in­hibitor ripretinib, for which it re­cent­ly inked a deal with De­ci­phera.

PD-1 in Chi­na is a huge mar­ket worth up to $14.2 bil­lion by 2030, Zai Lab said, and on­ly $0.1 bil­lion of that has been un­locked so far — leav­ing room for mul­ti­ple win­ners.

In­cyte — which paid $150 mil­lion up­front to bag 012 af­ter its first PD-1 from Chi­na’s Hen­grui ex­pe­ri­enced a safe­ty is­sue — grabs an im­me­di­ate $17.5 mil­lion from this deal, with de­vel­op­ment and sales mile­stones up to $60 mil­lion. The drug­mak­er is al­so re­tain­ing an op­tion to co-pro­mote with Zai Lab in Chi­na while let­ting the Chi­nese part­ner in on its on­go­ing glob­al clin­i­cal tri­als.

“To us, from a BD per­spec­tive, this is a pret­ty es­tab­lished PD-1,” CEO Saman­tha Du said, high­light­ing the tri­als that In­cyte has con­duct­ed.

No­tably, Zai Lab’s de­vel­op­ment and com­mer­cial rights cov­er both on­col­o­gy and hema­tol­ogy, though ex­ecs say they don’t cur­rent­ly have any plans on the lat­ter.

A pi­o­neer in the busi­ness of in­tro­duc­ing West­ern drugs to Chi­na and de­sign­ing clin­i­cal plans tai­lored for a do­mes­tic pa­tient pop­u­la­tion, Zai Lab has al­so been ramp­ing up in­ter­nal dis­cov­ery un­der new CSO Va­le­ria Fan­tin.

While there are no ex­ist­ing PD-1/L1 as­sets in the port­fo­lio, they might have bis­pe­cif­ic an­ti­bod­ies in­volv­ing a check­point, Du added.

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.

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.
