Karyopharm shares tank af­ter FDA in­sid­ers slam their case on the ef­fi­ca­cy of a can­cer drug with “sig­nif­i­cant tox­i­c­i­ty”

Karyopharm’s at­tempt to gain an ac­cel­er­at­ed ap­proved for se­linex­or as a treat­ment for drug-re­sis­tant cas­es of mul­ti­ple myelo­ma is in se­ri­ous jeop­ardy. And in­vestors know it.

Their stock $KP­TI plum­met­ed 46% as an­a­lysts ab­sorbed a high­ly crit­i­cal as­sess­ment of their drug — an oral XPO1 in­hibitor — ahead of next Tues­day’s ex­pert pan­el re­view.

Giv­en the his­to­ry of the FDA with these kinds of re­views, Tues­day’s as­sess­ment will like­ly be harsh.

Bat­ting back the op­ti­mistic as­sess­ment the biotech gave se­linex­or, the in­ter­nal FDA re­view con­cludes that there’s pre­cious lit­tle ev­i­dence that the drug has any sig­nif­i­cant val­ue on its own. Just as bad, the drug has been tied to high rates of tox­i­c­i­ty and a high­er death rate when it was test­ed in a ran­dom­ized con­trolled study for acute myeloid leukemia.

“Treat­ment with se­linex­or is as­so­ci­at­ed with sig­nif­i­cant tox­i­c­i­ty,” the re­view states un­am­bigu­ous­ly. The sin­gle arm study that is be­ing used to seek ac­cel­er­at­ed ap­proval demon­strat­ed a 60% rate of se­ri­ous ad­verse events. Al­most 9 out of 10 pa­tients re­quired a dose mod­i­fi­ca­tion due to serous drug re­ac­tions. And a quar­ter of the pa­tients bowed out of the study.

The com­bi­na­tion drug that was used in their pro­posed piv­otal — dex­am­etha­sone — has a his­tor­i­cal re­sponse rate of 10-27% at high dos­es, says the FDA. They could see no re­sponse for the drug when used as a monother­a­py, and even as a com­bo they could see on­ly “lim­it­ed ef­fi­ca­cy.” 

As for the claimed over­all re­sponse rate of 25%, most of those were on­ly par­tial re­spons­es.

An­oth­er chal­lenge: There are 9 drugs ap­proved for treat­ing mul­ti­ple myelo­ma — 4 in the last 4 years. The im­plic­it ques­tion there is, why should the agency ap­prove this drug as num­ber 10?

Giv­en the lim­it­ed ef­fi­ca­cy and sig­nif­i­cant tox­i­c­i­ty demon­strat­ed in this pop­u­la­tion, it is un­clear whether treat­ment with se­linex­or-dex­am­etha­sone pro­vides a clin­i­cal­ly mean­ing­ful ben­e­fit that out­weighs the risks of treat­ment. The lim­i­ta­tions of in­ter­pret­ing safe­ty and ef­fi­ca­cy from a sin­gle arm tri­al, and lack of sin­gle agent ac­tiv­i­ty of se­linex­or cou­pled with his­tor­i­cal da­ta show­ing ac­tiv­i­ty of dex­am­etha­sone in RRMM, add to the chal­lenges in in­ter­pret­ing the re­sults of the piv­otal study in sup­port of the pro­posed in­di­ca­tion.

That’s not good.

An­oth­er black eye was earned for the com­pa­ny’s at­tempt to sup­ply some re­al world ev­i­dence to back up their pitch — which the FDA es­sen­tial­ly re­ject­ed. And an­a­lysts didn’t over­look the vot­ing ques­tion: Should the agency wait for the piv­otal Phase III da­ta from the BOSTON study be­fore the drug hits the mar­ket?

It doesn’t take a ge­nius to fill in the blank on that one.

Jonathan Chang at SVB Leerink notes:

While we were ful­ly ex­pect­ing the tox­i­c­i­ties of se­linex­or to be a key dis­cus­sion point, we view ques­tion­ing the in­ter­pretabil­i­ty of se­linex­or’s ef­fi­ca­cy da­ta as a neg­a­tive sur­prise. Our MEDA­Corp KOL checks have in­di­cat­ed that ef­fi­ca­cy da­ta from the STORM study sug­gest that se­linex­or is an ac­tive drug. No­tably, some of the ef­fi­ca­cy da­ta cit­ed by the FDA for dex alone are gen­er­at­ed in an ear­li­er-line pa­tient pop­u­la­tion (our da­ta ta­bles at­tached). The draft vot­ing ques­tion for the pan­el is “Should ap­proval of se­linex­or be de­layed un­til re­sults of the ran­dom­ized phase 3 tri­al, BOSTON, are avail­able?”. Re­call the Phase III BOSTON study is eval­u­at­ing se­linex­or + Vel­cade + dex (SVd) vs. Vel­cade + dex (Vd) in re­lapsed/re­frac­to­ry mul­ti­ple myelo­ma with da­ta ex­pect­ed by YE19. Ul­ti­mate­ly, po­ten­tial de­lay of ap­proval un­til the BOSTON re­sults are avail­able would be a neg­a­tive up­date vs. our as­sump­tions.

Novotech CRO Ex­pands Chi­na Team as Biotech De­mand for Clin­i­cal Tri­als In­creas­es up to 79%

An increase in demand of up to 79% for clinical trials in China has prompted Novotech the Asia-Pacific CRO to rapidly expand the China team, appointing expert local clinical executives to their Shanghai and Hong Kong offices. The company is planning to expand their team by 30% over the next quarter.

Novotech China has seen considerable demand recently which is borne out by research from GlobalData:
A global migration of clinical research is occurring from high-income countries to low and middle-income countries with emerging economies. Over the period 2017 to 2018, for example, the number of clinical trial sites opened by biotech companies in Asia-Pacific increased by 35% compared to 8% in the rest of the world, with growth as high as 79% in China.
Novotech CEO Dr John Moller said China offers the largest population in the world, rapid economic growth, and an increasing willingness by government to invest in research and development.
Novotech’s 23 years of experience working in the region means we are the ideal CRO partner for USA biotechs wanting to tap the research expertise and opportunities that China offers.
There are over 22,000 active investigators in Greater China, with about 5,000 investigators with experience on at least 3 studies (source GlobalData).

UP­DAT­ED: Gilead un­leash­es a $5B late-stage cash al­liance with Gala­pa­gos — lay­ing out O'­Day's R&D strat­e­gy

Daniel O’Day is executing his first major development deal since taking over as CEO of Gilead $GILD. And he’s going in deep to ally himself with a longstanding partner.

O’Day announced today that he is spending $5 billion in cash to add new late-stage drugs to Gilead’s pipeline, picking up rights to Galapagos’ $GLPG Phase III IPF drug GLPG1690 alongside adoption of the biotech’s Phase IIb drug GLPG1972 for osteoarthritis. And Gilead is also putting billions more on the table for milestones, gaining options for everything else in Galapagos’ pipeline, with a shot at all rights outside of Europe.

Altogether, Gilead is gaining rights to 6 clinical-stage assets, 20 preclinical programs and everything else being hatched in translation.

Ab­b­Vie beefs up the on­col­o­gy pipeline, bag­ging an up­start STING play­er with its own unique ap­proach

AbbVie isn’t letting its $63 billion buyout of Allergan stop its M&A/deals team from continuing their work.

Monday morning we learned that the pharma giant is snapping up tiny Mavupharma out of Seattle, a Frazier-backed startup that has its own unique take on STING — which is on the threshold of their first clinical trial.

Stimulating STING has been a big disappointment in biopharma, with setbacks at Merck and Aduro. But Mavupharma was focused on its own target: ENPP1, which they say acted as a “negative regulator” of STING. Take the foot off the brake, they theorized, and you would have a new approach to I/O that could have a wide variety of implications in cancers.

Billing it­self as the first AI biotech to launch hu­man tri­als, Re­cur­sion adds $121M C round

Billing itself as the first AI biotech with programs in the clinic, Salt Lake City-based Recursion now has a $121 million bankroll to start gathering human data to see if it’s on the right track. 

“We’re trying to build this discovery engine,” Recursion CEO Chris Gibson tells me ahead of the C round news. “We now have the first two programs in the clinic.” And that, he adds, qualifies as a first for any AI establishment “that actually have something in the clinic.”

Hal Bar­ron's team at GSK scores a win with pos­i­tive Ze­ju­la PhI­II front­line study — now comes the hard part

Score one for Hal Barron and the new R&D team steering GlaxoSmithKline’s pipeline.

The pharma giant reported this morning that its recently acquired PARP, Zejula (niraparib), hit the primary endpoint on progression-free survival in a frontline maintenance setting for women suffering ovarian cancer — following chemo and regardless of their BRCA status.

GSK bet $5 billion on the Tesaro buyout primarily to get this drug, drawing the shaking heads of biopharma. Why pay a big premium for a drug like this when AstraZeneca was going from strength to strength with Lynparza, ran the argument, having won a hugely important accelerated approval to jump out ahead — way ahead — of the rest of the PARP players? Lynparza — now co-owned by a powerhouse cancer team at Merck — won the first approval in frontline maintenance in ovarian cancer.

FDA bats back As­traZeneca's SGLT di­a­betes drug for Type 1 di­a­betes — block­ing a class on safe­ty fears

The FDA has just fired its latest salvo at the SGLT class of diabetes drugs, blowing up some commercial opportunity at AstraZeneca as part of the collateral damage.

The pharma giant reported early Monday that the FDA has rejected its blockbuster drug Farxiga for Type 1 diabetes that can’t be controlled by insulin. And while the pharma giant maintained its usual grim silence in the face of a setback, this one should be easy to interpret.

GSK to tap Jonathan Symonds as chair­man, lever­ag­ing Big Phar­ma ex­pe­ri­ence for con­sumer biz deal

Six months into its search for a new board chairman, GlaxoSmithKline has apparently found the perfect candidate in a seasoned executive groomed at AstraZeneca and Novartis. Jonathan Symonds is in the final stages of being appointed, Bloomberg reports.

In January Sir Philip Hampton announced his intention to step down and make way for a new leader to oversee the consumer health joint venture GSK is setting up with Pfizer. The deal — announced a month prior — would spin out the unit formerly headed by GSK CEO Emma Walmsley and merge it with the equivalent division at Pfizer to create a new entity to be listed separately.

UP­DAT­ED: Am­gen, No­var­tis scrap Alzheimer's stud­ies — is BACE fi­nal­ly dead or will Bio­gen and Ei­sai car­ry on?

The BACE theory of controlling Alzheimer’s died with failed pivotal projects at Merck, Eli Lilly and their partners at AstraZeneca. Now Amgen and Novartis have come along to bulldoze it under a mound of safety threats — leaving only Biogen and Eisai to carry on with a less than zero chance of success — with the notable addition that they may actually be doing harm to patients.

After the market closed Thursday, Amgen and Novartis announced that they were dumping two pivotal programs underway with the Banner Alzheimer’s Institute on their BACE drug CNP520 (umibecestat) after an independent review of the data indicated that patients’ cognitive abilities were actually worsening at a faster pace than the placebo arm.

Fresh out of Eli Lil­ly, Christi Shaw sur­faces as Daniel O'­Day's new CEO at CAR-T pi­o­neer Kite

Well, that didn’t take long. 

We found out Thursday evening that Christi Shaw has given up her top post as the head of the Bio-Medicines group at Eli Lilly for the helm at CAR-T pioneer Kite. New Gilead CEO Daniel O’Day, a Roche veteran, had made finding a Kite CEO a top priority on his arrival at Gilead. And he went right for a headliner.

O’Day was clearly excited about the coup.

“We conducted an extensive search for a new leader at Kite and we believe that Christi’s unique set of skills will allow us to continue to build on our leadership position in cell therapy,” he said in a prepared statement. “Christi’s vast experience across complex therapeutic areas, and particularly in oncology, will serve Kite very well. She is clearly a leader who will bring teams and individuals together and I am confident she will build upon the entrepreneurial spirit at Kite as we seek to help more people with cancer around the world.”
