In­vestors fret as VBI's hep B vac­cine fails key sec­ondary PhI­II study goal

Sobered by mount­ing costs, Dy­navax $DVAX last month made the de­ci­sion to fo­cus all its re­sources on its 2017-ap­proved he­pati­tis B vac­cine Hep­lisav-B, which ri­vals and su­per­sedes the ef­fi­ca­cy and con­ve­nience pro­file of GSK’s $GSK es­tab­lished En­ger­ix-B. The Cal­i­for­nia-based com­pa­ny will be on the look­out for an­oth­er com­peti­tor — VBI Vac­cines, which on Mon­day un­veiled late-stage da­ta on its hep B vac­cine: Sci-B-Vac.

Sci-B-Vac, which has al­ready se­cured ap­proval in Is­rael and 10 oth­er coun­tries, is in Phase III de­vel­op­ment in North Amer­i­ca and Eu­rope. It is en­gi­neered to mim­ic all three sur­face anti­gens of the hep B virus to in­duce a po­tent im­mune re­sponse and is be­ing de­vel­oped to work at low­er dos­es than ex­ist­ing hep B vac­cines.

VBI on Mon­day broke out da­ta from the PRO­TECT study, in which 1,607 sub­jects aged 18 years and old­er were ei­ther giv­en a three-dose course of Sci-B-Vac (10 µg) or a three-dose course of En­ger­ix-B (20 µg).

Sci-B-Vac failed to show that two dos­es of the drug were equal­ly ef­fec­tive as three dos­es of En­ger­ix-B in the study — a key sec­ondary end­point. In­vestors were not im­pressed, and the Cam­bridge, Mass­a­chu­setts-based com­pa­ny’s shares $VBIV cratered 58% tak­ing VBI in­to pen­ny stock ter­ri­to­ry at 81 cents be­fore the open­ing bell on Mon­day.

Mean­while, the VBI vac­cine was found to be as pro­tec­tive as En­ger­ix-B at the end of the third vac­ci­na­tion — meet­ing the main goal of the study. In fact, da­ta showed that the rate of sero­pro­tec­tion (an an­ti­body re­sponse ca­pa­ble of pre­vent­ing in­fec­tion) — was 91.4% for Sci-B-Vac-treat­ed sub­jects, ver­sus 76.5% for En­ger­ix-B — a sta­tis­ti­cal­ly sig­nif­i­cant dif­fer­ence.

In ad­di­tion, the sero­pro­tec­tion rate (SPR) in sub­jects aged 45 and over was 89.4% for Sci-B-Vac, ver­sus 73.1% for En­ger­ix-B af­ter the third vac­ci­na­tion — meet­ing the co-pri­ma­ry end­point. It al­so cleared oth­er sec­ondary goals in sub-analy­ses strat­i­fied by age, gen­der, body mass in­dex, di­a­bet­ic sta­tus and smok­ing sta­tus.

Jeff Bax­ter VBI

Da­ta from an­oth­er late-stage tri­al, CON­STANT, com­par­ing Sci-B-Vac and En­ger­ix-B is ex­pect­ed by the end of 2019. Pend­ing the suc­cess­ful com­ple­tion of CON­STANT, VBI is on to sub­mit mar­ket­ing ap­pli­ca­tions in the U.S., Eu­rope, and Cana­da next year, com­pa­ny chief Jeff Bax­ter said on Mon­day.

Hep B is trans­mit­ted through con­tact with blood and bod­i­ly flu­ids of an in­fect­ed per­son and is a high­ly in­fec­tious virus, 50 to 100 times more in­fec­tious than HIV — even slight laps­es in in­fec­tion con­trol can re­sult in pa­tient-to-pa­tient trans­mis­sion. Since the ear­ly 1990’s the Unit­ed States has im­ple­ment­ed vac­ci­na­tion pro­grams in new­born chil­dren, but those born be­fore re­main sus­cep­ti­ble. CDC da­ta now sug­gests 95% per­cent of new hep B in­fec­tions in the Unit­ed States oc­cur in adults, as there is no stan­dard­ized sys­tem for vac­ci­nat­ing peo­ple af­ter school age, and par­tic­u­lar­ly since spikes in in­jec­tion drug use may be lead­ing to acute out­breaks.

Af­ter be­ing linked to a string of in­ex­plic­a­ble safe­ty is­sues, Hep­lisav-B was fi­nal­ly ap­proved in No­vem­ber 2017. De­spite its check­ered path to the fin­ish line, the vac­cine’s ef­fi­ca­cy and con­ve­nience pro­file su­per­sedes En­ger­ix-B.

In an­oth­er dis­ap­point­ment for in­vestors, FDA slaps down Bio­haven’s re­vised ver­sion of an old ALS drug

Biohaven is at risk of making a habit of disappointing its investors. 

Late Friday the biotech $BHVN reported that the FDA had rejected its application for riluzole, an old drug that they had made over into a sublingual formulation that dissolves under the tongue. According to Biohaven, the FDA had a problem with the active ingredient used in a bioequivalence study back in 2017, which they got from the Canadian drugmaker Apotex.

Medicxi is rolling out its biggest fund ever to back Eu­rope's top 'sci­en­tists with strange ideas'

Francesco De Rubertis built Medicxi to be the kind of biotech venture player he would have liked to have known back when he was a full time scientist.

“When I was a scientist 20 years ago I would have loved Medicxi,’ the co-founder tells me. It’s the kind of place run by and for investigators, what the Medicxi partner calls “scientists with strange ideas — a platform for the drug hunter and scientific entrepreneur. That’s what I wanted when I was a scientist.”

Af­ter a decade, Vi­iV CSO John Pot­tage says it's time to step down — and he's hand­ing the job to long­time col­league Kim Smith

ViiV Healthcare has always been something unique in the global drug industry.

Owned by GlaxoSmithKline and Pfizer — with GSK in the lead as majority owner — it was created 10 years ago in a time of deep turmoil for the field as something independent of the pharma giants, but with access to lots of infrastructural support on demand. While R&D at the mother ship inside GSK was souring, a razor-focused ViiV provided a rare bright spot, challenging Gilead on a lucrative front in delivering new combinations that require fewer therapies with a more easily tolerated regimen.

They kept a massive number of people alive who would otherwise have been facing a death sentence. And they made money.

And throughout, John Pottage has been the chief scientific and chief medical officer.

Until now.

Chas­ing Roche's ag­ing block­buster fran­chise, Am­gen/Al­ler­gan roll out Avastin, Her­ceptin knock­offs at dis­count

Let the long battle for biosimilars in the cancer space begin.

Amgen has launched its Avastin and Herceptin copycats — licensed from the predecessors of Allergan — almost two years after the FDA had stamped its approval on Mvasi (bevacizumab-awwb) and three months after the Kanjinti OK (trastuzumab-anns). While the biotech had been fielding biosimilars in Europe, this marks their first foray in the US — and the first oncology biosimilars in the country.

No­var­tis hands off 3 pre­clin­i­cal pro­grams to the an­tivi­ral R&D mas­ters at Gilead

Gilead CEO Daniel O’Day’s new task hunting up a CSO for the company isn’t stopping the industry’s dominant antiviral player from doing pipeline deals.

The big biotech today snapped up 3 preclinical antiviral programs from pharma giant Novartis, with drugs promising to treat human rhinovirus, influenza and herpes viruses. We don’t know what the upfront is, but the back end has $291 million in milestones baked in.

On a hot streak, No­var­tis ex­ecs run the odds on their two most im­por­tant PhI­II read­outs. Which is 0.01% more like­ly to suc­ceed?

Novartis CEO Vas Narasimhan is living in the sweet spot right now.

The numbers are running a bit better than expected, the pipeline — which he assembled as development chief — is performing and the stock popped more than 4% on Thursday as the executive team ran through their assessment of Q2 performance.

Year-to-date the stock is up 28%, so the investors will be beaming. Anyone looking for chinks in their armor — and there are plenty giving it a shot — right now focus on payer acceptance of their $2.1 million gene therapy Zolgensma, where it’s early days. And CAR-T continues to underperform, but Novartis doesn’t appear to be suffering from it.

So what could go wrong?

Actually, not much. But Tim Anderson at Wolfe pressed Narasimhan and his development chief John Tsai to pick which of two looming Phase III readouts with blockbuster implication had the better odds of success.

H1 analy­sis: The high-stakes ta­ble in the biotech deals casi­no is pay­ing out some record-set­ting win­nings

For years the big trend among dealmakers at the major players has been centered on ratcheting down upfront payments in favor of bigger milestones. Better known as biobucks for some. But with the top 15 companies competing for the kind of “transformative” pacts that can whip up some excitement on Wall Street, with some big biotechs like Regeneron now weighing in as well, cash is king at the high stakes table.

We asked Chris Dokomajilar, the head of DealForma, to crunch the numbers for us, looking over the top 20 deals for the past decade and breaking it all down into the top alliances already created in 2019. Gilead has clearly tipped the scales in terms of the coin of the bio-realm, with its record-setting $5 billion upfront to tie up to Galapagos’ entire pipeline.

Dokomajilar notes:

We’re going to need a ‘three comma club’ for the deals with over $1 billion in total upfront cash and equity. The $100 million-plus club is getting crowded at 164 deals in the last decade with new deals being added towards the top of the chart. 2019 already has 14 deals with at least $100 million in upfront cash and equity for a total year-to-date of over $9 billion. That beats last year’s $8 billion and sets a record.

Add upfronts and equity payments and you get $11.5 billion for the year, just shy of last year’s record-setting $11.8 billion.
