BioCryst shares are blast­ed as a PhI­II HAE 'suc­cess' un­der­whelms an­a­lysts

It was de­signed to be the oral fix for hered­i­tary an­gioede­ma (HAE) — a rare, po­ten­tial­ly life-threat­en­ing ge­net­ic dis­or­der — but BioCryst Phar­ma­ceu­ti­cal’s ex­per­i­men­tal cap­sule has un­der­whelmed in a piv­otal late-stage study, de­spite meet­ing the pri­ma­ry end­point.

Two dos­es of the oral drug, BCX7353, (110 mg and 150 mg) were in­ves­ti­gat­ed in a 121-pa­tient, place­bo-con­trolled tri­al called APeX-2 for the pre­ven­tion of an­gioede­ma at­tacks — re­cur­rent episodes of se­vere swelling com­mon­ly in the limbs, face, in­testi­nal tract, and air­way.

Both dos­es met the main goal of re­duc­ing the rate of at­tacks. The high­er dose di­min­ished the at­tack rate by 44% ver­sus place­bo (p<0.001),  while the low­er dose cut the at­tack rate by 30% (p=0.024). That didn’t cut it on Wall Street, though. An­a­lysts have long sug­gest­ed a rate of at least 50% would en­sure BCX7353 would be com­pet­i­tive in a mar­ket that is cur­rent­ly mo­nop­o­lized by high­ly ef­fec­tive in­jecta­bles.

Shares of North Car­oli­na-based BioCryst $BCRX were halved in pre­mar­ket trad­ing.

In­jectable med­ica­tions, such as Shire’s 2018-ap­proved lanadelum­ab, can re­duce HAE at­tack fre­quen­cy by about 80%. “(W)e would’ve thought the drug’s ef­fi­ca­cy would’ve need­ed to at least near that of (Shire’s old­er HAE in­jectable) Cin­ryze in or­der for it to be dis­rup­tive to the HAE treat­ment land­scape,” Stifel an­a­lysts wrote in a note.

Need­ham an­a­lysts not­ed re­cent­ly:

Based on dis­cus­sions with KOLs, ef­fi­ca­cy rates in the 50%-range would be suf­fi­cient for an oral prod­uct to play a sig­nif­i­cant role in HAE pro­phy­lax­is mar­ket giv­en the high de­mand for oral al­ter­na­tives. Re­call, Cin­ryze was a game-chang­er for HAE pa­tients de­spite IV dos­ing of every 3-4 days and ef­fi­ca­cy rates of ~50%. The po­ten­tial of BCX7353 in HAE pro­phy­lax­is hinges on meet­ing stat sig in APeX-2, with an ef­fi­ca­cy rate of at least 50% and a clean safe­ty/tol­er­a­bil­i­ty pro­file.

UP­DAT­ED: In sur­prise switch, Bris­tol-My­ers is sell­ing off block­buster Ote­zla, promis­ing to com­plete Cel­gene ac­qui­si­tion — just lat­er

Apart from revealing its checkpoint inhibitor Opdivo blew a big liver cancer study on Monday, Bristol-Myers Squibb said its plans to swallow Celgene will require the sale of blockbuster psoriasis treatment Otezla to keep the Federal Trade Commission (FTC) at bay.

The announcement — which has potentially delayed the completion of the takeover to early 2020 — irked investors, triggering the New York-based drugmaker’s shares to tumble Monday morning in premarket trading.

Celgene’s Otezla, approved in 2014 for psoriasis and psoriatic arthritis, is a rising star. It generated global sales of $1.6 billion last year, up from the nearly $1.3 billion in 2017. Apart from the partial overlap of Bristol-Myers injectable Orencia, the company’s rival oral TYK2 psoriasis drug is in late-stage development, after the firm posted encouraging mid-stage data on the drug, BMS-986165, last fall. With Monday’s decision, it appears Bristol-Myers is favoring its experimental drug, and discounting Otezla’s future.

The move blindsided some analysts. Credit Suisse’s Vamil Divan noted just days ago:

Novotech CEO Dr. John Moller

Novotech CRO Award­ed Frost & Sul­li­van Best Biotech CRO Asia-Pa­cif­ic 2019

Known in the in­dus­try as the Asia-Pa­cif­ic CRO, Novotech is now lead CRO ser­vices provider for the grow­ing num­ber of in­ter­na­tion­al biotechs se­lect­ing the re­gion for their stud­ies.

Re­flect­ing this Asia-Pa­cif­ic growth, Novotech staff num­bers are up 20% since De­cem­ber 2018 to 600 in-house clin­i­cal re­search peo­ple across a full range of ser­vices, across the re­gion.

Novotech’s ca­pa­bil­i­ties have been rec­og­nized by an­a­lysts like Frost & Sul­li­van, most re­cent­ly with the pres­ti­gious Asia-Pa­cif­ic CRO Biotech of the year award for best prac­tices in clin­i­cal re­search for biotechs for the fifth year. See oth­er awards here.

Fol­low­ing news of job cuts in Eu­ro­pean R&D ops, Sanofi con­firms it’s of­fer­ing US work­ers an 'ear­ly ex­it'

Ear­li­er in the week we learned that Sanofi was bring­ing out the bud­get ax to trim 466 R&D jobs in Eu­rope, re­tool­ing its ap­proach to car­dio as re­search chief John Reed beefed up their work in can­cer and gene ther­a­pies. And we’re end­ing the week with news that the phar­ma gi­ant has al­so been qui­et­ly re­duc­ing staff in the US, tar­get­ing hun­dreds of jobs as the com­pa­ny push­es vol­un­tary buy­outs with a fo­cus on R&D sup­port ser­vices.

Suf­fer­ing No­var­tis part­ner Cona­tus is pack­ing it in on NASH af­ter a se­ries of un­for­tu­nate tri­al events

The NASH par­ty is over at No­var­tis-backed Cona­tus. And this time they’re turn­ing off the lights.

More than 2 years af­ter No­var­tis sur­prised the biotech in­vest­ment com­mu­ni­ty with its $50 mil­lion up­front and promise of R&D sup­port to part­ner with the lit­tle biotech on NASH — ig­nit­ing a light­ning strike for the share price — Cona­tus $CNAT is back with the lat­est bit­ter tale to tell about em­ri­c­as­an, which once in­spired con­fi­dence at the phar­ma gi­ant.

Bris­tol-My­ers star Op­di­vo fails sur­vival test in a matchup with Nex­avar aimed at shak­ing up the big HCC mar­ket

Bris­tol-My­ers Squibb has suf­fered an­oth­er painful set­back in its years-long quest to ex­pand the reach of Op­di­vo. The phar­ma gi­ant this morn­ing not­ed that their Check­mate-459 study com­par­ing Op­di­vo with Bay­er’s Nex­avar in front­line cas­es of he­pa­to­cel­lu­lar car­ci­no­ma — the most com­mon form of liv­er can­cer — failed to hit the pri­ma­ry end­point on over­all sur­vival.

This was a sig­nif­i­cant mile­stone in Bris­tol-My­ers’ tal­ly of PD-1 cat­a­lysts this year. Nex­avar (so­rafenib) has been the stan­dard of care in front­line HCC for the past decade, though Op­di­vo has been mak­ing head­way in sec­ond-line HCC cas­es, where it’s go­ing toe-to-toe with Bay­er’s Sti­var­ga (re­go­rafenib) af­ter re­cent ap­provals shook up the mar­ket.

Bet­ter than Am­bi­en? Min­er­va soars on PhI­Ib up­date on sel­torex­ant for in­som­nia

A month af­ter roil­ing in­vestors with what skep­tics dis­missed as cher­ry pick­ing of its de­pres­sion da­ta, Min­er­va is back with a clean slate of da­ta from its Phase IIb in­som­nia tri­al.

In a de­tailed up­date, the Waltham, MA-based biotech said sel­torex­ant (MIN-202) hit both the pri­ma­ry and sev­er­al sec­ondary end­points, ef­fec­tive­ly im­prov­ing sleep in­duc­tion and pro­long­ing sleep du­ra­tion. In­ves­ti­ga­tors made a point to note that the ef­fects were con­sis­tent across the adult and el­der­ly pop­u­la­tions, with the lat­ter more prone to the sleep dis­or­der.

Gene ther­a­py biotech sees its stock rock­et high­er on promis­ing re­sults for rare cas­es of but­ter­fly dis­ease

Shares of Krys­tal Biotech took off this morn­ing $KRYS af­ter the lit­tle biotech re­port­ed promis­ing re­sults from its gene ther­a­py to treat a rare skin dis­ease called epi­der­mol­y­sis bul­losa.

Fo­cus­ing on an up­date with 4 new pa­tients, re­searchers spot­light­ed the suc­cess of KB103 in clos­ing some stub­born wounds. Krys­tal says that of 4 re­cur­ring and 2 chron­ic skin wounds treat­ed with the gene ther­a­py, the KB103 group saw the clo­sure of 5. The 6th — a chron­ic wound, de­fined as a wound that had re­mained open for more than 12 weeks — was par­tial­ly closed. That brings the to­tal so far to 8 treat­ed wounds, with 7 clo­sures.

Ab­b­Vie gets a green light to re­sume re­cruit­ing pa­tients for one myelo­ma study — but Ven­clex­ta re­mains un­der a cloud

Three months af­ter reg­u­la­tors at the FDA forced Ab­b­Vie to halt en­rolling pa­tients in its tri­als of a com­bi­na­tion us­ing Ven­clex­ta (vene­to­clax) to treat drug-re­sis­tant cas­es of mul­ti­ple myelo­ma, the agency has green-light­ed the re­sump­tion of one of those stud­ies, while keep­ing the rest on the side­lines.

The CANO­VA (M13-494) study can now get back in busi­ness re­cruit­ing pa­tients to test the drug for a pop­u­la­tion that shares a par­tic­u­lar ge­net­ic bio­mark­er. To get that per­mis­sion, Ab­b­Vie — which is part­nered with Roche on this pro­gram — was forced to re­vise the pro­to­col, mak­ing un­spec­i­fied changes in­volv­ing risk mit­i­ga­tion mea­sures, pro­to­col-spec­i­fied guide­lines and an up­dat­ed fu­til­i­ty cri­te­ria.

Mike Grey. Mirum

In $86M IPO pitch, Mirum spells out plans to turn Shire dis­cards in­to or­phan liv­er drug suc­cess­es

Mike Grey doesn’t have any time to waste. Hav­ing re­gained con­trol of two liv­er dis­ease drugs from Shire and po­si­tioned them for piv­otal stud­ies — five years af­ter first hand­ing them off in a deal to sell Lu­me­na, where he was CEO — Grey is steer­ing Mirum straight in­to an IPO with a $86 mil­lion ask.

Not that Mirum has spent much of its $120 mil­lion Se­ries A cash since launch­ing last No­vem­ber. Ac­cord­ing to the S-1, the Cal­i­forn­ian biotech has burned through $23.3 mil­lion as of March, but ex­pects ex­pens­es to pick up once their clin­i­cal work gath­ers steam.
