FDA snubs Zo­genix's an­ti-seizure drug, not hap­py with some slop­py, in­ad­e­quate R&D work

Nine months af­ter Zo­genix got a stock ral­ly $ZGNX go­ing by tout­ing late-stage da­ta for a new drug to pre­vent seizures due to Dravet syn­drome, the FDA hand­ed back their mar­ket­ing ap­pli­ca­tion with a fail­ing grade on in­ad­e­quate and in­com­plete work. Of­fi­cial­ly, that’s called a refuse-to-file no­tice, which is al­ways em­bar­rass­ing.

It’s not the end of the world, says Zo­genix in a man­ner of speak­ing, but the agency was not hap­py that the biotech had sub­mit­ted an in­cor­rect ver­sion of a dataset with the NDA and fault­ed the com­pa­ny as “cer­tain non-clin­i­cal stud­ies were not sub­mit­ted to al­low as­sess­ment of the chron­ic ad­min­is­tra­tion of fen­flu­ramine.”

In­vestors didn’t like it at all. The biotech, with a mar­ket cap of $2.2 bil­lion, saw its shares tank on the news – plung­ing 32% af­ter the bell.

The EMA, though, hasn’t had any prob­lems with their ap­pli­ca­tion so far, ac­cept­ing it for re­view with an ex­pect­ed de­ci­sion in Q1 2020. And Sti­fle’s Paul Mat­teis is dis­con­cert­ed by the whole thing.

We find the RTF let­ter for Fin­tepla dis­con­cert­ing, some­what bizarre, and rea­son enough to push back Fin­tepla US rev­enues to 2021 (at a slight­ly re­duced prob­a­bil­i­ty-ad­just­ment), con­ser­v­a­tive­ly as­sum­ing a mean­ing­ful de­lay. That be­ing said, the pre­clin­i­cal tox­i­col­o­gy ask from FDA is le­git­i­mate­ly puz­zling: re­mem­ber, Zo­genix has treat­ed >200 Dravet pa­tients out to 1-year and is cur­rent­ly con­duct­ing a Fin­tepla LGS tri­al that in­cludes an OLE; you’d think that FDA would’ve asked for, or been com­fort­able with, pri­or pre­clin­i­cal tox­i­col­o­gy stud­ies be­fore sign­ing off on the con­duct of ex­ten­sion tri­als.

It was a much dif­fer­ent sto­ry back in the sum­mer of 2018, when com­pa­ny ex­ecs tout­ed pos­i­tive da­ta from their sec­ond Phase III study, not­ing that 43 pa­tients on their drug had a 62.7% drop in seizures, com­pared to 1.2% in the place­bo arm. At that point, the drug was shap­ing up as a di­rect com­peti­tor to GW Phar­ma’s Epid­i­olex, which wowed the in­dus­try with its cannabi­noid ap­proach to re­duc­ing seizures. That drug is billed as a block­buster.

Zo­genix’s drug fen­flu­ramine, you might re­call, was one half of the no­to­ri­ous di­et drug fen-Phen. The biotech says they didn’t see any car­dio is­sues in their small stud­ies, but it does beg the ques­tion on just how high reg­u­la­tors may have raised the bar for an ap­proval — or even ac­cep­tance of an NDA.

“We re­main high­ly con­fi­dent in Fin­tepla’s clin­i­cal pro­file demon­strat­ed in the Phase 3 pro­gram in Dravet syn­drome and are com­mit­ted to ad­vanc­ing the prod­uct can­di­date as a po­ten­tial new treat­ment op­tion for this and oth­er rare and of­ten cat­a­stroph­ic epilep­tic en­cephalopathies,” said CEO Stephen Farr.

The top 10 block­buster drugs in the late-stage pipeline — Eval­u­ate adds 6 new ther­a­pies to heavy-hit­ter list

Vertex comes in for a substantial amount of criticism for its no-holds-barred tactical approach toward wresting the price it wants for its commercial drugs in Europe. But the flip side of that coin is a highly admired R&D and commercial operation that regularly wins kudos from analysts for their ability to engineer greater cash flow from the breakthrough drugs they create.

Both aspects needed for success in this business are on display in the program backing Vertex’s triple for cystic fibrosis. VX-659/VX-445 + Tezacaftor + Ivacaftor — it’s been whittled down to 445 now — was singled out by Evaluate Pharma as the late-stage therapy most likely to win the crown for drug sales in 5 years, with a projected peak revenue forecast of $4.3 billion.

The latest annual list, which you can see here in their latest world preview, includes a roster of some of the most closely watched development programs in biopharma. And Evaluate has added 6 must-watch experimental drugs to the top 10 as drugs fail or go on to a first approval. With apologies to the list maker, I revamped this to rank the top 10 by projected 2024 sales, instead of Evaluate's net present value rankings.

It's how we roll at Endpoints News.

Here is a quick summary of the rest of the top 10:

How small- to mid-sized biotechs can adopt pa­tient cen­tric­i­ty in their on­col­o­gy tri­als

By Lucy Clos­sick Thom­son, Se­nior Di­rec­tor of On­col­o­gy Pro­ject Man­age­ment, Icon

Clin­i­cal tri­als in on­col­o­gy can be cost­ly and chal­leng­ing to man­age. One fac­tor that could re­duce costs and re­duce bar­ri­ers is har­ness­ing the pa­tient voice in tri­al de­sign to help ac­cel­er­ate pa­tient en­roll­ment. Now is the time to adopt pa­tient-cen­tric strate­gies that not on­ly fo­cus on pa­tient needs, but al­so can main­tain cost ef­fi­cien­cy.

In­vestor day prep at Mer­ck in­cludes a new strat­e­gy to pick up the pace on M&A — re­port

Mer­ck’s re­cent deals to buy up two bolt-on biotechs — Ti­los and Pelo­ton — weren’t an aber­ra­tion. In­stead, both ac­qui­si­tions mark a new strat­e­gy to beef up its dom­i­nant can­cer drug op­er­a­tions cen­tered on Keytru­da while look­ing to ad­dress grow­ing con­cerns that too many of its eggs are in the one I/O bas­ket for their PD-1 pro­gram. And Mer­ck is go­ing af­ter more small- and mid-sized buy­outs to calm those fears.

'It's a growth play': Catal­ent ac­quires Bris­tol-My­er­s' Eu­ro­pean launch pad, ex­pand­ing glob­al CD­MO ops

Catalent is staying on the growth track.

Just two months after committing $1.2 billion to pick up Paragon and take a deep dive into the sizzling hot gene therapy manufacturing sector, the CDMO is bouncing right back with a deal to buy out Bristol-Myers’ central launchpad for new therapies in Europe, acquiring a complex in Anagni, Italy, southwest of Rome, that will significantly expand its capacity on the continent.

There are no terms being offered, but this is no small deal. The Anagni campus employs some 700 staffers, and Catalent is planning to go right in — once the deal closes late this year — with a blueprint to build up the operations further as they expand on oral solid, biologics, and sterile product manufacturing and packaging.

This is an uncommon deal, Catalent CEO John Chiminski tells me. But it offers a shortcut for rapid growth that cuts years out of developing a green fields project. That’s time Catalent doesn’t have as the industry undergoes unprecedented expansion around the world.

Right back at you, Pfiz­er: BeiGene and a Pfiz­er spin­out launch a new­co to de­vel­op a MEK/BRAF in­hibitor that could ri­val $11.4B com­bo

A day af­ter Pfiz­er bought Ar­ray and its ap­proved can­cer com­bo, BeiGene and Pfiz­er spin­out Spring­Works have part­nered in launch­ing a new biotech that has an eye on the very same mar­ket the phar­ma gi­ant just paid bil­lions for. And they’re plan­ning on us­ing an ex-Pfiz­er drug to do it.

In a nut­shell, Chi­na’s BeiGene is toss­ing in a pre­clin­i­cal BRAF in­hibitor — BGB-3245, which cov­ers both V600 and non-V600 BRAF mu­ta­tions — for a big stake in a new, joint­ly con­trolled biotech called Map­Kure with Bain-backed Spring­Works.

Sanofi aligns it­self with Google to stream­line drug de­vel­op­ment

Tech­nol­o­gy is bleed­ing in­to health­care, and big phar­ma is rid­ing the wave. Sanofi $SNY ap­point­ed its first chief dig­i­tal of­fi­cer this Feb­ru­ary, fol­low­ing the foot­steps of its peers. By May, the French drug­mak­er and some of its big phar­ma com­pa­tri­ots joined forces with Google par­ent Al­pha­bet’s Ver­i­ly unit to aug­ment clin­i­cal tri­al re­search. On Tues­day, the Parisian com­pa­ny tied up with Google to ac­cess its cloud com­put­ing and ar­ti­fi­cial in­tel­li­gence tech to spur the de­vel­op­ment of new ther­a­pies.

UP­DAT­ED: Roche fields first ap­proval for Ro­z­lytrek in the run-up to a show­down with Bay­er, Pfiz­er

While it’s wait­ing to hear back from FDA reg­u­la­tors, Roche is be­gin­ning the vic­to­ry lap for en­trec­tinib in Japan.

Roche is giv­ing Bay­er a run for their mon­ey with this tu­mor-ag­nos­tic drug, which tar­gets NTRK gene fu­sions. Now dubbed Ro­z­lytrek, it’s sanc­tioned to treat adult and pe­di­atric pa­tients in Japan with neu­rotroph­ic ty­ro­sine re­cep­tor ki­nase fu­sion-pos­i­tive, ad­vanced re­cur­rent sol­id tu­mors.

Arc­turus ex­pands col­lab­o­ra­tion, adding $30M cash; Ku­ra shoots for $100M raise

→  Rare dis­ease play­er Ul­tragenyx $RARE is ex­pand­ing its al­liance with Arc­turus $ARCT, pay­ing $24 mil­lion for eq­ui­ty and an­oth­er $6 mil­lion in an up­front as the two part­ners ex­pand their col­lab­o­ra­tion to in­clude up to 12 tar­gets. “This ex­pand­ed col­lab­o­ra­tion fur­ther so­lid­i­fies our mR­NA plat­form by adding ad­di­tion­al tar­gets and ex­pand­ing our abil­i­ty to po­ten­tial­ly treat more dis­eases,” said Emil Kakkis, the CEO at Ul­tragenyx. “We are pleased with the progress of our on­go­ing col­lab­o­ra­tion. Our most ad­vanced mR­NA pro­gram, UX053 for the treat­ment of Glyco­gen Stor­age Dis­ease Type III, is ex­pect­ed to move in­to the clin­ic next year, and we look for­ward to fur­ther build­ing up­on the ini­tial suc­cess of this part­ner­ship.”
