Bio­haven touts a pair of PhI­II wins for mi­graine pill, but shares ric­o­chet off of weak da­ta

Bio­haven has re­leased a set of pos­i­tive Phase III da­ta for their fast-act­ing mi­graine drug, which close­ly par­al­lel a ri­val at Al­ler­gan and trail well be­hind Eli Lil­ly’s las­mid­i­tan. And the biotech will now join the scram­ble un­der­way for an ap­proval in a field that’s about to be se­vere­ly dis­rupt­ed.

In­vestors didn’t like the num­bers ear­ly Mon­day morn­ing, send­ing shares $BHVN down 40%. That clear­ly wasn’t the way Bio­haven was bet­ting. The biotech paid Bris­tol-My­ers Squibb $50 mil­lion just a cou­ple of weeks ago to re­struc­ture their li­cens­ing deal, cut­ting the roy­al­ty stream to the sin­gle dig­its. But in the hours up to the close, the stock — backed by some heavy­weight mar­ket play­ers — went on a roller coast­er ride in the red, end­ing the day down 7%.

Al­ler­gan — which will have an­oth­er Phase III tri­al to re­port on — saw its shares rise a bit, while Lil­ly stock jumped close to 2%.

The co-pri­ma­ry end­points for Bio­haven’s oral rimegepant (BHV-3000) was pain free­dom and free­dom from most both­er­some symp­tom 2 hours af­ter tak­ing the pill in two piv­otal stud­ies.

Their pain free­dom rate was 19.2% and 19.6% for the drug, ver­sus 14.2% and 12% for the place­bo arm. Free­dom from MBS was 37.6% and 36.6% ver­sus 25.2% and 27.7% in the sug­ar pill group.

That ev­i­dent­ly may have been sta­tis­ti­cal­ly sig­nif­i­cant, but it wasn’t a big enough spread to con­vince skep­tics won­der­ing about the drug’s clin­i­cal sig­nif­i­cance in a com­pet­i­tive field.

Com­pare rimegepant to Al­ler­gan’s oral CGRP ubro­gepant, where the first Phase III re­port­ed out free­dom for pain at 2 hours for 19.2% and 21.2% for two dif­fer­ent dos­es and 11.8% in the place­bo arm; 38.6% and 37.7% on MBS and 27.8% in the place­bo arm.

Eli Lil­ly’s las­mid­i­tan — which works by hit­ting 5-HT1F re­cep­tors — did even bet­ter, de­spite be­ing dogged by high place­bo rates. Lil­ly $LLY, which paid $960 mil­lion to buy CoLu­cid and las­mid­i­tan, al­so has a CGRP drug that has per­formed in line with the rest of the in­jecta­bles.

Two hours af­ter tak­ing las­mid­i­tan or a place­bo, here were the the lat­est Phase III re­spons­es on free­dom from pain by dosage: 28.6% for 50 mg (p=0.003); 31.4% for 100 mg (p<0.001); 38.8% for 200 mg (p<0.001) and 21.3% for place­bo. In­ves­ti­ga­tors al­so nailed an end­point on free­ing pa­tients of their most both­er­some symp­tom, whether that was nau­sea, sen­si­tiv­i­ty to sound or sen­si­tiv­i­ty to light. The da­ta: 40% for 50 mg (p=0.009); 44.2% for 100 mg (p<0.001); 48.7% for 200 mg (p<0.001) and 33.5% for place­bo.

Back-to-back Phase II­Is, how­ev­er, won’t trans­late in­to a quick FDA fil­ing. Bio­haven not­ed in a re­lease that it won’t be ready to file un­til 2019, keep­ing up with Al­ler­gan on that score.

Vlad Coric

The ri­vals here are bet­ting that they can take mar­ket share for treat­ing mi­graines as heavy­weights com­pete over in­jectable CGRP drugs head­ed to reg­u­la­tors for the pre­ven­tion of acute mi­graine. Am­gen and No­var­tis lead the way on that front, with a drug un­der re­view. Te­va, and Alder are an­gling for a fol­lowup po­si­tion.

The one com­mon char­ac­ter­is­tic of these drugs is that they all per­form in re­mark­ably sim­i­lar ways, leav­ing oral de­liv­ery and price as two fea­tures that these two new ther­a­pies can com­pete on. Al­ler­gan has al­so had to ex­plain some cas­es of liv­er tox in its first Phase III — a con­cern for the class — while Bio­haven says it saw noth­ing to alarm in­ves­ti­ga­tors in its Phase III stud­ies.

Bio­haven CEO Vlad Coric had this to say:

By com­bin­ing pos­i­tive ef­fi­ca­cy re­sults and a fa­vor­able safe­ty pro­file with ease of oral dos­ing, we be­lieve that rimegepant will rep­re­sent a sig­nif­i­cant im­prove­ment over ex­ist­ing treat­ment op­tions.

Bio­haven shares al­so took a beat­ing last fall when their Phase II/III study of tri­grilu­zole demon­strat­ed not on­ly that it didn’t work bet­ter than a place­bo in treat­ing spin­ocere­bel­lar atax­ia, but pa­tients in the study al­so re­port­ed in larg­er num­bers that the place­bo helped them more than the drug.

In a stun­ning set­back, Amarin los­es big patent fight over Vas­cepa IP. And its high-fly­ing stock crash­es to earth

Amarin’s shares $AMRN were blitzed Monday evening, losing billions in value as reports spread that the company had lost its high-profile effort to keep its Vascepa patents protected from generic drugmakers.

Amarin had been fighting to keep key patents under lock and key — and away from generic rivals — for another 10 years, but District Court Judge Miranda Du in Las Vegas ruled against the biotech. She ruled that:
(A)ll the Asserted Claims are invalid as obvious under 35 U.S.C.§ 103. Thus, the Court finds in favor of Defendants on Plaintiff’s remaining infringementclaim, and in their favor on their counterclaims asserting the invalidity of the AssertedClaims under 35 U.S.C. § 103.

UP­DAT­ED: Have a new drug that promis­es to fight Covid-19? The FDA promis­es fast ac­tion but some de­vel­op­ers aren't hap­py

After providing an emergency approval to use malaria drugs against coronavirus with little actual evidence of their efficacy or safety in that setting, the FDA has already proven that it has set aside the gold standard when it comes to the pandemic. And now regulators have spelled out a new approach to speeding development that promises immediate responses in no uncertain terms — promising a program offering the ultimate high-speed pathway to Covid-19 drug approvals.

Once fu­ri­ous over No­var­tis’ da­ta ma­nip­u­la­tion scan­dal, the FDA now says it’s noth­ing they need to take ac­tion on

Back in the BP era — Before Pandemic — the FDA ripped Novartis for its decision to keep the agency in the dark about manipulated data used in its application for Zolgensma while its marketing application for the gene therapy was under review.

Civil and criminal sanctions were being discussed, the agency noted in a rare broadside at one of the world’s largest pharma companies. Notable lawmakers cheered the angry regulators on, urging the FDA to make an example of Novartis, which fielded Zolgensma at $2.1 million — the current record for a one-off therapy.

Covid-19 roundup: GSK, Am­gen tai­lor R&D work to fit the coro­n­avirus age; Doud­na's ge­nomics crew launch­es di­ag­nos­tic lab

You can add Amgen and GSK to the list of deep-pocket drug R&D players who are tailoring their pipeline work to fit a new age of coronavirus.

Following in the footsteps of a lineup of big players like Eli Lilly — which has suspended patient recruitment for drug studies — Amgen and GSK have opted to take a more tailored approach. Amgen is intent on circling the wagons around key studies that are already fully enrolled, and GSK has the red light on new studies while the pandemic plays out.

As­traZeneca says its block­buster Farx­i­ga proved to be a game-chang­er in CKD — wrap­ping PhI­II ear­ly

If the FDA can still hold up its end of the bargain, AstraZeneca is already on a short path to scooping up a cutting-edge win with a likely approval for their SGLT2 drug Farxiga in cutting the risk of heart failure. Now the pharma giant says it can point to solid evidence that the drug — initially restricted to diabetes — also works for chronic kidney disease, potentially adding a blockbuster indication for the franchise.

The race to de­vel­op Covid-19 drugs and vac­cines is on — here’s what’s hap­pen­ing in the UK

Weeks away from the results of ongoing US and China trials testing its experimental antiviral remdesivir, Gilead is going to trial the failed Ebola drug in a small group of coronavirus patients in England and Scotland. The United Kingdom is also home to a range of other therapeutic efforts, as the pandemic rages on across the globe.

On Tuesday, Southampton, UK-based startup Synairgen kicked off a mid-stage placebo-controlled study testing its experimental drug, SNG001 — an inhaled formulation of interferon-beta-1a — that has previously shown to be safe and effective in improving lung function in asthma patients with a respiratory viral infection in a pair of Phase II trials.

‘There was a grow­ing weari­ness’: Rush­ing against a pan­dem­ic clock, As­pen Neu­ro­sciences se­cures $70M Se­ries A

Just before Christmastime, Howard Federoff got a tip from Washington: There was a new virus in China. And this one could be bad.

News report of the virus had not yet appeared. Federoff, a neuroscientist, was briefed because years before, he was vetted as part of a group — he didn’t give a name for the group — to consult for the US government on emerging scientific issues. His day job, though, was CEO of Aspen Neurosciences, a Parkinson’s cell therapy startup that days before had come out of stealth mode and gave word to investors they were hoping to raise $70 million. That, Federoff realized, would be difficult if a pandemic shut down the global economy.

FDA puts pe­di­atric aGVHD drug on pri­or­i­ty re­view lane — will they go vir­tu­al with the ad­comm?

Despite worries about regulatory delays due to new work arrangements under Covid-19, the FDA appears intent to go full speed ahead with its everyday work, not only granting priority review to a stem cell therapy for acute graft versus host disease but also plotting an advisory committee meeting for it.

With a PDUFA date of September 30, the journey of the drug — remestemcel-L, or Ryoncil — could shed light on the agency’s capacity to facilitate drug development unrelated to Covid-19.

Covid-19 roundup: Trump push­es his new fa­vorite, untest­ed drug; CRISPR out­lines crip­pling im­pact of Covid-19

President Trump has a new favorite Covid-19 drug.

After a conversation with Japanese Prime Minister Shinzo Abe, Politico reports, the president is pressuring the FDA to issue emergency use authorization for favipiravir, a flu drug that showed glimpses of success in China but remains unproven and carries a list of worrying side effects. The push comes after a week-plus in which the White House touted a potentially effective but unproven malaria medication despite the concerns of scientific advisors such as NIAID director Anthony Fauci. And Trump ally Rudy Giuliani has been talking up unproven cell therapy efforts on Twitter.
