Loxo takes cen­ter stage at AS­CO with its ground­break­ing shot at a bio­mark­er-based can­cer drug ap­proval

CHICA­GO — Loxo On­col­o­gy made it in­to the AS­CO show­case over the week­end, boast­ing of a small but grow­ing num­ber of cas­es where chil­dren and adults with TRK fu­sion can­cer re­spond­ed to their lead drug, larotrec­tinib (LOXO-101). And they’re pack­ag­ing it in­to a new drug ap­pli­ca­tion they ex­pect to hus­tle to reg­u­la­tors ei­ther lat­er this year or ear­ly 2018, while show­ing off a next-gen drug com­ing up the pipeline that they’re al­ready claim­ing has es­tab­lished proof-of-con­cept ev­i­dence of ef­fi­ca­cy in two cas­es.

This Stam­ford, CT-based biotech $LOXO is all about hus­tle.

For a small com­pa­ny with just 35 staffers, Loxo has enor­mous am­bi­tions that in­clude shoot­ing at some ground­break­ing ad­vances in drug de­vel­op­ment. At AS­CO, the biotech boast­ed a 76% tu­mor re­sponse rate among pa­tients with mul­ti­tude of dif­fer­ent tu­mor types. Un­like a typ­i­cal can­cer drug fo­cused on the anato­my, Loxo is go­ing af­ter a bio­mark­er — tropomyosin re­cep­tor ki­nase (TRK) fu­sions — and at AS­CO it cob­bled to­geth­er re­sponse da­ta from three ear­ly-stage tri­als.

Specif­i­cal­ly there were 50 pa­tients — 43 adults and 12 chil­dren — with 12% com­plete and 64% par­tial re­spon­ders. That’s a high rate of suc­cess and it fits with their ear­li­er state­ments on progress in the clin­ic. Small groups of pa­tients like this are al­so not un­usu­al for a can­cer type shared by on­ly a few thou­sand US pa­tients.

The in­vestor crowd ate it up. Loxo’s shares spiked 51% mid­day Mon­day.

Just days ago Mer­ck won the first pi­o­neer­ing ap­proval for the ge­net­i­cal­ly de­fined use of a can­cer drug, an­oth­er boost for its glob­al star Keytru­da. Larotrec­tinib is be­ing pushed down the same path­way, but it is ex­per­i­men­tal. And Loxo is the po­lar op­po­site of a gi­ant like Mer­ck, which has been pour­ing cash in­to its well-es­tab­lished Keytru­da pro­gram in si­mul­ta­ne­ous pur­suit of dozens of tar­gets.

Josh Bilenker, Loxo On­col­o­gy

Go­ing af­ter an FDA ap­proval for both chil­dren and adults like this “has nev­er been done be­fore,” Loxo CEO Josh Bilenker tells me. But he is ab­solute­ly con­vinced that the da­ta he has is enough to form the ba­sis of a win­ning ap­pli­ca­tion.

It’s not un­usu­al these days to see bio­phar­ma com­pa­nies use ear­ly-stage da­ta to go af­ter an ac­cel­er­at­ed ap­proval at the FDA. What was once the ex­cep­tion is now the rule. But Loxo — which part­nered with Ar­ray on the pro­gram — is press­ing the en­ve­lope, us­ing small groups of pa­tients across Phase I and II tri­als to pro­vide the ev­i­dence they need that larotrec­tinib works. That strat­e­gy is nec­es­sary to achieve their goal, they say, and they have the agency’s break­through ther­a­py des­ig­na­tion to pro­vide an open door, which Bilenker says led to a meet­ing with the FDA 18 months ago that set them on this path.

As a pub­lic com­pa­ny, Loxo al­so has tout­ed — and ben­e­fit­ed — from just about every scrap of da­ta ex­ecs can lay its hands on, with new in­stances of par­tial re­spons­es used to rev up its stock price.

In Chica­go Sat­ur­day, that strat­e­gy was on full view as they not­ed the first glim­mer of ev­i­dence that its next-gen drug LOXO-195 trig­gered two par­tial re­spons­es af­ter it was used in emer­gency cas­es in­volv­ing re­sis­tance to a TRK fu­sion in­hibitor.

Cour­tesy Loxo On­col­o­gy.

If in fact they can prove that it can work against cas­es of TRK fu­sion drug re­sis­tance, their drug could be­come a reg­u­lar part of the treat­ment land­scape for pa­tients with their bio­mark­er. And they will tout any ev­i­dence of ef­fi­ca­cy they gath­er on their next trip to reg­u­la­tors.

Loxo’s mar­ket cap is up to $1.3 bil­lion as some mar­ket an­a­lysts cheer them at every stage.

Loxo, though, al­so has com­pe­ti­tion in the field. Igny­ta $RXDX has a Phase II un­der­way for en­trec­tinib for TRK-fu­sion pos­i­tive adult and pe­di­atric pa­tients. Just a cou­ple of weeks ago Igny­ta won their own break­through stays for their drug, giv­ing them the same easy ac­cess that Loxo en­joys. And not all an­a­lysts are ig­nor­ing the po­ten­tial for a matchup as these two small out­fits com­pete for the lime­light in can­cer R&D.

“The com­pa­ny guid­ed for NDAs for Trk+ and ROS1+ pts in 2018 and a U.S. launch in 2019 (MAA sub­mis­sion in 2019),” not­ed Jef­feries re­cent­ly. “The break­through des­ig­na­tion for en­trec­tinib helps lev­el the play­ing field some with LOXO-101, which re­ceived BTD in Ju­ly 2016 (NDA sub­mis­sion ex­pect­ed in late-2017 or ear­ly-2018).”

If they do make it to the mar­ket, Bilenker says Loxo plans to set up a com­mer­cial group and launch this it­self. “We own world­wide rights to the drug and that’s our plan,” he says, shrug­ging off the sug­ges­tion of a com­pa­ny sale.

It’s a big goal.

BREAK­ING: Ab­b­Vie seals $63B deal to buy a trou­bled Al­ler­gan

Brent Saunders has found his way out of the current fix he’s in at Allergan $AGN. He’s selling the company to AbbVie for $63 billion in the latest example of the hot M&A market in biopharma.

AbbVie $ABBV has agreed to pay $188.24 a share — cash and stock — for the troubled Allergan, reflecting a 45% premium as investors bid up shares in anticipation of a much buzzed about company split. That price — with each share of Allergan worth 0.8660 AbbVie shares and $120.30 in cash — reflects a sharp fall from the $330 peak for Allergan and Saunders 4 years ago — but much better than anything shareholders had in mind for the near future.

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:

Eye­ing a $500M peak sales pot, Almi­rall dou­bles down on le­brik­izum­ab as Der­mi­ra lines up PhI­II

With eyes on what it be­lieves is a $500 mil­lion peak rev­enue op­por­tu­ni­ty in Eu­rope, Barcelona-based Almi­rall has stepped up with $50 mil­lion in cash to take up the op­tion on Der­mi­ra’s IL-13 an­ti-in­flam­ma­to­ry drug le­brik­izum­ab just ahead of the start of Phase III. And there’s an­oth­er $30 mil­lion due as the late-stage pro­gram gets geared up.

That shouldn’t be long from now, as Der­mi­ra ex­pects to be­gin the late-stage tri­al work for atopic der­mati­tis be­fore the end of this year as it fol­lows a trail that ex­ecs in­sist leads to block­buster re­turns. Along the way, they’ll need to take on the 600-pound go­ril­la in atopic der­mati­tis: the IL-13/IL-4 drug Dupix­ent, from Re­gen­eron and Sanofi. Ri­vals al­so in­clude Leo Phar­ma, in its piv­otal with tralok­izum­ab, and Anap­tys­Bio in the hunt with a mid-stage pro­gram for etokimab, pre­vi­ous­ly re­ferred to as ANB020.

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.

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.

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.
