Gen­script re­bounds on HKEX with staunch de­fense of Leg­end Biotech's CAR-T da­ta in­tegri­ty

Af­ter a scathing short re­port trig­gered a land­slide for Gen­script’s stock and forced it to halt trad­ing, the com­pa­ny has man­aged to sal­vage some of that loss with a re­sponse is­sued Fri­day morn­ing.

In the state­ment, Gen­script kicked back against the al­le­ga­tions lev­eled against Nan­jing Leg­end Biotech, its sub­sidiary de­vel­op­ing a J&J-part­nered CAR-T ther­a­py. Their Hong Kong-list­ed shares has risen al­most 16% from the low­est point Thurs­day.

“The com­pa­ny de­nies all al­le­ga­tions against the com­pa­ny in the re­port,” the state­ment reads. “The claims in the re­port are mis­lead­ing, bi­ased, se­lec­tive, in­ac­cu­rate and in­com­plete, con­tain­ing base­less al­le­ga­tions and ir­re­spon­si­ble con­jec­ture. The com­pa­ny does not have any in­for­ma­tion on Flam­ing Re­search, and has no record of Flam­ing Re­search con­tact­ing our man­age­ment.”

Top among the at­tacks: Leg­end ma­nip­u­lat­ed the da­ta that took AS­CO by sur­prise in 2017.

Flam­ing Re­search, the ob­scure firm cred­it­ed for the short re­port, wrote that Leg­end’s CAR-T da­ta came from three “well rec­og­nized hema­tol­ogy hos­pi­tals” in Shang­hai and Jiang­su, and one mediocre hos­pi­tal in Xi’an. But it was the re­searchers in Xi’an who of­fered the most com­pelling da­ta, where­as the da­ta from the oth­er sites didn’t hold up.

That’s not se­lec­tive dis­clo­sure at all, Gen­script says; the rea­son why they didn’t present any­thing from Shang­hai and Jiang­su at AS­CO was that the tri­als start­ed af­ter con­fer­ence da­ta were due. And when they did pub­lish the da­ta at ASH lat­er that year, the over­all re­sponse rate was still 100%.

Of the 11 cas­es of re­frac­to­ry mul­ti­ple myelo­ma re­port­ed, they point out, eight achieved strin­gent com­plete re­sponse (73%), two achieved very good par­tial re­sponse, and one achieved par­tial re­sponse.

Flam­ing Re­search al­so got some ba­sic facts wrong in their re­port, Gen­script says. For in­stance, it claimed Leg­end’s CAR-T em­ploys the CD28 cos­tim­u­la­to­ry do­main when it in fact us­es 4-1BB.

The com­pa­ny al­so stands by its R&D team — led by Leg­end founder and CSO Xi­ao­hu Fan — its IP prospects and the way it han­dled its death re­port­ing, point­ing to US and Chi­na IND clear­ances as ev­i­dence of its clean reg­u­la­to­ry record.

The in­ci­dent, wide­ly re­port­ed by Chi­nese me­dia, al­so rais­es ques­tions about the volatil­i­ty of the HKEX at a crit­i­cal time as non-rev­enue biotechs start go­ing pub­lic on the ex­change and in­vestors have their eyes opened about the ups and downs of drug de­vel­op­ment.

Alex­ion wins pri­or­i­ty re­view for Ul­tomiris' aHUS in­di­ca­tion; FDA ex­pands ap­proval of Ver­tex's Symdeko

→ Alex­ion $ALXN has scored a speedy re­view for Ul­tomiris for pa­tients with atyp­i­cal he­molyt­ic ure­mic syn­drome (aHUS) af­ter post­ing pos­i­tive da­ta from a piv­otal study in Jan­u­ary. The drug is the rare dis­ease com­pa­ny’s shot at pro­tect­ing its block­buster blood dis­or­der fran­chise that is cur­rent­ly cen­tered around its flag­ship drug, Soliris, which is a com­ple­ment in­hibitor typ­i­cal­ly ad­min­is­tered every two weeks. Ul­tomiris has a sim­i­lar mech­a­nism of ac­tion but re­quires less-fre­quent dos­ing — every eight weeks. The de­ci­sion date has been set to Oc­to­ber 19. Late last year, Ul­tomiris se­cured ap­proval for noc­tur­nal he­mo­glo­bin­uria (PNH) pa­tients.

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:

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.

Why would the FDA ap­prove an­oth­er con­tro­ver­sial drug to spur a woman’s li­bido with these da­ta? And why no ex­pert pan­el re­view?

AMAG Pharmaceuticals’ newly approved drug for spurring women’s sexual desire may never make much money, but it’s a big hit at sparking media attention.

The therapy — Vyleesi (bremelanotide) — got the green light from regulators on Friday evening, swiftly lighting up a range of stories around the world, from The New York Times to The Guardian. Several headlines inevitably referred to it as the “female Viagra,” invoking Pfizer’s old erectile dysfunction blockbuster.

But the two drugs have little in common.

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.

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.
