Man­u­fac­tur­ing is­sues hob­ble Heron's quest to mar­ket its long-act­ing non-opi­oid painkiller

The C-suite at Paci­ra like­ly sighed in re­lief on Wednes­day, as their main ri­val, Heron Ther­a­peu­tics, was hand­ed an un­ex­pect­ed FDA re­jec­tion — re­lat­ed to man­u­fac­tur­ing con­cerns — for a com­pet­ing long-act­ing non-opi­oid painkiller for post-sur­gi­cal anal­ge­sia.

The health reg­u­la­tor has asked for ad­di­tion­al in­for­ma­tion re­lat­ed to Heron’s chem­istry, man­u­fac­tur­ing and con­trols and oth­er non-clin­i­cal da­ta — and has not iden­ti­fied any safe­ty or ef­fi­ca­cy is­sues, nor asked for ex­tra clin­i­cal stud­ies and da­ta analy­ses for the drug, HTX-011, Heron said.

Paci­ra in­vestors cheered the an­nounce­ment, lift­ing the com­pa­ny’s stock $PCRX more than 16% to $46.25 be­fore the bell. Mean­while, Heron shares $HRTX tum­bled more than 26% to $16.01 pre­mar­ket.

Heron plans to li­aise with the FDA to re­solve their con­cerns, and re­sub­mit its mar­ket­ing ap­pli­ca­tion as soon as pos­si­ble, chief Bar­ry Quart said in a state­ment.

The man­u­fac­tur­ing is­sues are like­ly solv­able, Cowen an­a­lysts wrote in a note, pre­dict­ing a new FDA de­ci­sion date in first half of next year.

As the US health reg­u­la­tor per­sists in its ef­fort to stem the tide of opi­oid abuse, over­dose and ad­dic­tion while the phar­ma­ceu­ti­cal ar­chi­tects of the pre­scrip­tion painkiller cri­sis face fierce scruti­ny, Heron Ther­a­peu­tics had de­signed the drug to take a bite out of the mar­ket that en­com­pass­es mil­lions of post­op­er­a­tive pa­tients who are can­di­dates for opi­oids. HTX-011 has shown in stud­ies to sub­due the need for opi­ates.

Heron is ini­tial­ly tar­get­ing rough­ly 13.5 mil­lion pa­tients who have un­der­gone the most painful pro­ce­dures (typ­i­cal­ly gen­er­al surgery, OB/GYN and plas­tic surgery). Many of these pa­tients are first giv­en a lo­cal anes­thet­ic like bupi­va­caine to dull the pain, but the ef­fects on­ly last about six hours or so, there­fore doc­tors tend to pre­scribe opi­oids to man­age se­vere pain that can last up to three days (de­pend­ing on the surgery).

HTX-011 is de­signed to slow­ly re­lease its two in­gre­di­ents: bupi­va­caine and the non-steroidal an­ti-in­flam­ma­to­ry drug (NSAID) meloxi­cam over a three-day pe­ri­od.

Bar­ry Quart

When you cut through tis­sue, and some­times bone, in­flam­ma­to­ry cy­tokines are re­leased. Apart from the in­flam­ma­tion that aris­es in re­sponse, these cy­tokines change the lo­cal PH of the in­ci­sion, mak­ing it more acidic (lo­cal anes­thet­ics tend to lose their po­ten­cy in acidic en­vi­ron­ments), and en­hance the sen­si­tiv­i­ty of nerve end­ings so even low lev­els of pain pro­duce a larg­er pain trans­mis­sion to the brain, Quart ex­plained in an in­ter­view with End­points News ahead of the FDA de­ci­sion.

“Adding a small amount of the NSAID meloxi­cam in­to our poly­mer for­mu­la­tion and re­leas­ing that si­mul­ta­ne­ous­ly over three days al­lowed us to block enough of that in­flam­ma­to­ry process,” Quart said. “We can show clear pain re­duc­tion for the full three days that the drug (HTX-011) is be­ing re­leased. It’s the first time — that we know of — that an ex­tend­ed-re­lease lo­cal anes­thet­ic of any kind re­gard­less of how its de­liv­ered has been able to beat bupi­va­caine so­lu­tion as stan­dard-of-care in large Phase III tri­als.”

Com­bin­ing HTX-011 with two over-the-counter oral anal­gesics (ac­eta­minophen and ibupro­fen) has yield­ed im­pres­sive re­sults in help­ing post-op pain pa­tients re­main opi­oid free in two stud­ies pub­lished by Heron this year.

In a 63-pa­tient study, 90% of pa­tients re­ceiv­ing HTX-011 with the OTC anal­gesic reg­i­men did not re­quire opi­oids to man­age their post­op­er­a­tive pain through 72 hours post her­nia surgery, com­pared to 51%, 40% and 22% of pa­tients re­ceiv­ing HTX-011, bupi­va­caine and a place­bo, Heron re­vealed in Jan­u­ary. Fol­low up af­ter 28 days showed 81% of pa­tients re­mained opi­oid-free.

Biren Amin

“We con­sid­er these re­sults as com­pelling, and sup­port­ing a best-in-class pro­file in post-op pain based on sig­nif­i­cant­ly more opi­oid-free pa­tients and sub­stan­tial­ly low­er opi­oid use. HTX-011 could of­fer the on­ly op­tion of opi­oid-free pre­scrip­tion at dis­charge, which re­mains a high pri­or­i­ty in the bat­tle against opi­oid abuse,” Jef­feries’ Biren Amin wrote in a note that month.

Apart from bupi­va­caine, HTX-011 will com­pete with Paci­ra Phar­ma­ceu­ti­cals’ J&J-part­nered, long-act­ing post-op painkiller Ex­par­el, which gen­er­at­ed net sales of about $331 mil­lion last year. Ex­par­el’s main in­gre­di­ent is al­so bupi­va­caine and the drug has been ap­proved by the US reg­u­la­tor since Oc­to­ber 2011 as a treat­ment for post­sur­gi­cal anal­ge­sia.

In a note pub­lished in March, SVB Leerink an­a­lysts wrote that while “Ex­par­el does a good job re­duc­ing opi­oid use for post-op pain; HTX-011 could do this bet­ter,” cit­ing a KOL sur­vey. “…it (Ex­par­el) has done a good job in re­duc­ing opi­oid use and hos­pi­tal­iza­tion time in its post-op­er­a­tive pa­tients, the du­ra­tion of ef­fi­ca­cy is in the 24-36 hour range. As such, this KOL be­lieves the longer po­ten­tial du­ra­tion of ef­fi­ca­cy and the in­stil­la­tion method of HTX-011 will re­sult in ini­tial use of the prod­uct. But up­on avail­abil­i­ty of both prod­ucts, this KOL be­lieves hos­pi­tals will run their own pi­lot stud­ies in var­i­ous sur­gi­cal mod­els to see how they com­pare to one an­oth­er.”

Over half the pa­tients Heron is tar­get­ing are re­ceiv­ing bupi­va­caine, and about 4% are get­ting Ex­par­el — the rest are get­ting var­i­ous “caines” such as li­do­caine, Quart said. “While we ob­vi­ous­ly ex­pect to take a cer­tain part of Ex­par­el mar­ket share…our pri­ma­ry tar­get is the 96% of pa­tients who are re­ceiv­ing…short-act­ing lo­cal anaes­thet­ics.”

Paci­ra, which un­veiled plans to swal­low a com­pa­ny that makes a sys­tem that us­es in­tense­ly cold ther­a­py on a spe­cif­ic nerve to re­lieve pain to com­ple­ment its flag­ship Ex­par­el treat­ment and for­ti­fy its pain fran­chise in March, is set to re­port is first-quar­ter re­sults on Thurs­day.

Year-on-year Ex­par­el rev­enue growth for 2019 is es­ti­mat­ed at 23%, Jef­feries an­a­lysts pre­dict­ed in a note last week. “(D)es­pite the strong re­cent (Ex­par­el) re­sults…cur­rent pen­e­tra­tion rates re­main very low…and the mar­ket is cer­tain­ly large enough to ac­com­mo­date two or more play­ers. In fact, we think the ad­di­tion­al voice of an­oth­er mar­ket­ing team rais­ing aware­ness for non-opi­oid post-sur­gi­cal pain op­tions ar­guably helps all mar­ket par­tic­i­pants. And per­haps most im­por­tant­ly, we view the sit­u­a­tion as less like ‘Coke vs Pep­si’ and more to the point that if un­bundling and ac­cess con­tin­ue to im­prove, all com­peti­tors in the seg­ment ben­e­fit.”

Ab­b­Vie gets its FDA OK for JAK in­hibitor upadac­i­tinib, but don’t look for this one to hit ex­ecs’ lofty ex­pec­ta­tions

Another big drug approval came through on Friday afternoon as the FDA OK’d AbbVie’s upadacitinib — an oral JAK1 inhibitor that is hitting the rheumatoid arthritis market with a black box warning of serious malignancies, infections and thrombosis reflecting fears associated with the class.

It will be sold as Rinvoq — at a wholesale price of $59,000 a year — and will likely soon face competition from a drug that AbbVie once controlled, and spurned. Reuters reports that a 4-week supply of Humira, by comparison, is $5,174, adding up to about $67,000 a year.

The top 10 fran­chise drugs in bio­phar­ma his­to­ry will earn a to­tal of $1.4T (tril­lion) by 2024 — what does that tell us?

Just in case you were looking for more evidence of just how important Amgen’s patent win on Enbrel is for the company and its investors, EvaluatePharma has come up with a forward-looking consensus estimate on what the list of top 10 drugs will look like in 2024.

UP­DAT­ED: Sci­en­tist-CEO ac­cused of im­prop­er­ly us­ing con­fi­den­tial in­fo from uni­corn Alec­tor

The executive team at Alector $ALEC has a bone to pick with scientific co-founder Asa Abeliovich. Their latest quarterly rundown has this brief note buried inside:

On June 18, 2019, we initiated a confidential arbitration proceeding against Dr. Asa Abeliovich, our former consulting co-founder, related to alleged breaches of his consulting agreement and the improper use of our confidential information that he learned during the course of rendering services to us as our consulting Chief Scientific Officer/Chief Innovation Officer. We are in the early stage of this arbitration proceeding and are unable to assess or provide any assurances regarding its possible outcome.

There’s no explicit word in the filing on what kind of confidential info was involved, but the proceeding got started 2 days ahead of Abeliovich’s IPO.

Abeliovich, formerly a tenured associate professor at Columbia, is a top scientist in the field of neurodegeneration, which is where Alector is targeted. More recently, he’s also helped start up Prevail Therapeutics as the CEO, which raised $125 million in an IPO. And there he’s planning on working on new gene therapies that target genetically defined subpopulations of Parkinson’s disease. Followup programs target Gaucher disease, frontotemporal dementia and synucleinopathies.

But this time Abeliovich is the CEO rather than a founding scientist. And some of their pipeline overlaps with Alector’s.

Abeliovich and Prevail, though, aren’t taking this one lying down.

Chi­na has be­come a CEO-lev­el pri­or­i­ty for multi­na­tion­al phar­ma­ceu­ti­cal com­pa­nies: the trend and the im­pli­ca­tions

After a “hot” period of rapid growth between 2009 and 2012, and a relatively “cooler” period of slower growth from 2013 to 2015, China has once again become a top-of-mind priority for the CEOs of most large, multinational pharmaceutical companies.

At the International Pharma Forum, hosted in March in Beijing by the R&D Based Pharmaceutical Association Committee (RDPAC) and the Pharmaceutical Research and Manufacturers of America (PhRMA), no fewer than seven CEOs of major multinational pharmaceutical firms participated, including GSK, Eli Lilly, LEO Pharma, Merck KGaA, Pfizer, Sanofi and UCB. A few days earlier, the CEOs of several other large multinationals attended the China Development Forum, an annual business forum hosted by the research arm of China’s State Council. It’s hard to imagine any other country, except the US, having such drawing power at CEO level.

As dis­as­ter struck, Ab­b­Vie’s Rick Gon­za­lez swooped in on Al­ler­gan with an of­fer Brent Saun­ders couldn’t say no to

Early March was a no good, awful, terrible time for Allergan CEO Brent Saunders. His big lead drug had imploded in a Phase III disaster and activists were after his hide — or at least his chairman’s title — as the stock price continued a steady droop that had eviscerated share value for investors.

But it was a perfect time for AbbVie CEO Rick Gonzalez to pick up the phone and ask Saunders if he’d like to consider a “strategic” deal.

As­traZeneca's jug­ger­naut PARP play­er Lyn­parza scoops up an­oth­er dom­i­nant win in PhI­II as the FDA adds a 'break­through' for Calquence

AstraZeneca’s oncology R&D group under José Baselga keeps churning out hits.

Wednesday morning the pharma giant and their partners at Merck parted the curtains on a successful readout for their Phase III PAOLA-1 study, demonstrating statistically significant improvement in progression-free survival for women with ovarian cancer in a first-line maintenance setting who added their PARP Lynparza to Avastin. This is their second late-stage success in ovarian cancer, which will help stave off rivals like GSK.

ICER blasts FDA, PTC and Sarep­ta for high prices on DMD drugs Em­flaza, Ex­ondys 51

ICER has some strong words for PTC, Sarepta and the FDA as the US drug price watchdog concludes that as currently priced, their respective new treatments for Duchenne muscular dystrophy are decidedly not cost-effective.

The final report — which cements the conclusions of a draft issued in May — incorporates the opinion of a panel of 17 experts ICER convened in a public meeting last month. It also based its analysis of Emflaza (deflazacort) and Exondys 51 (eteplirsen) on updated annual costs of $81,400 and over $1 million, respectively, after citing “incorrect” lower numbers in the initial calculations.
