FDA ap­proves first non-opi­oid to treat with­draw­al symp­toms in adults

The opi­oid ad­dic­tion mar­ket got a new play­er Wednes­day with the FDA ap­proval of Luce­myra, a pill that helps pa­tients man­age symp­toms of with­draw­al.

The drug, which has been used in the Unit­ed King­dom for more than two decades now, is made by Louisville, KY-based US WorldMeds. The spe­cial­ty phar­ma was not grant­ed ap­proval to treat opi­oid use dis­or­der, but in­stead to treat symp­toms of with­draw­al.

For those ad­dict­ed to opi­oids, quit­ting cold turkey can be a har­row­ing ex­pe­ri­ence. In as lit­tle as a few hours, pa­tients may ex­pe­ri­ence stom­ach cramps, mus­cle aches and spasms, a pound­ing heart, nau­sea, vom­it­ing and di­ar­rhea. Oth­er symp­toms in­clude anx­i­ety, ag­i­ta­tion, de­pres­sion and in­som­nia.

The NIH says these symp­toms aren’t di­rect­ly life-threat­en­ing, but they can dri­ve the pa­tient back to opi­oid use — of­ten over­dos­ing af­ter ex­pe­ri­enc­ing with­draw­al.

“We know that the phys­i­cal symp­toms of opi­oid with­draw­al can be one of the biggest bar­ri­ers for pa­tients seek­ing help and ul­ti­mate­ly over­com­ing ad­dic­tion,” said FDA com­mis­sion­er Scott Got­tlieb in a state­ment. “The fear of ex­pe­ri­enc­ing with­draw­al symp­toms of­ten pre­vents those suf­fer­ing from opi­oid ad­dic­tion from seek­ing help. And those who seek as­sis­tance may re­lapse due to con­tin­ued with­draw­al symp­toms.”

Luce­myra (lofex­i­dine hy­drochlo­ride) was orig­i­nal­ly in­tend­ed to be a hy­per­ten­sion drug. It re­duces the re­lease of nor­ep­i­neph­rine, a hor­mone be­lieved to play a key role in trig­ger­ing with­draw­al symp­toms. In two ran­dom­ized, dou­ble-blind, place­bo-con­trolled tri­als, 866 adult pa­tients demon­strat­ed the ben­e­fits and safe­ty of the drug. Com­pared to the place­bo group, pa­tients treat­ed with Luce­myra re­port­ed a low­er sever­i­ty of symp­toms. Plus, pa­tients who got Luce­myra were more like­ly to com­plete the course of treat­ment, which can on­ly last for up to 14 days.

The FDA is re­quir­ing 15 ad­di­tion­al stud­ies to fur­ther as­sess the drug’s safe­ty when used in chil­dren, for longer than 14 days, and in oth­er sit­u­a­tions that were not test­ed in the ear­li­er tri­als.

It will be in­ter­est­ing to see whether a drug like Luce­myra com­petes or is used in tan­dem with drugs like Sublo­cade, the in­jectable ver­sion of In­di­v­ior’s pop­u­lar opi­oid use dis­or­der drug Sub­ox­one. Sublo­cade, a month­ly in­jec­tion of buprenor­phine, con­tains a mild opi­oid to help stymie with­draw­al symp­toms for ad­dicts quit­ting opi­oid use.

Sublo­cade is ap­proved to treat opi­oid abuse dis­or­der, but it al­so con­tains opi­oids itelf. Some pa­tients — or doc­tors — may pre­fer an op­tion like Luce­myra to ease with­draw­al symp­toms, as it the drug does not con­tain opi­oids.

“To­day’s ap­proval rep­re­sents the first FDA-ap­proved non-opi­oid treat­ment for the man­age­ment of opi­oid with­draw­al symp­toms and pro­vides a new op­tion that al­lows providers to work with pa­tients to se­lect the treat­ment best suit­ed to an in­di­vid­ual’s needs,” said Sharon Hertz, di­rec­tor of the Di­vi­sion of Anes­the­sia, Anal­ge­sia and Ad­dic­tion Prod­ucts at the FDA.

Biotech Half­time Re­port: Af­ter a bumpy year, is biotech ready to re­bound?

The biotech sector has come down firmly from the highs of February as negative sentiment takes hold. The sector had a major boost of optimism from the success of the COVID-19 vaccines, making investors keenly aware of the potential of biopharma R&D engines. But from early this year, clinical trial, regulatory and access setbacks have reminded investors of the sector’s inherent risks.

RBC Capital Markets recently surveyed investors to take the temperature of the market, a mix of specialists/generalists and long-only/ long-short investment strategies. Heading into the second half of the year, investors mostly see the sector as undervalued (49%), a large change from the first half of the year when only 20% rated it as undervalued. Around 41% of investors now believe that biotech will underperform the S&P500 in the second half of 2021. Despite that view, 54% plan to maintain their position in the market and 41% still plan to increase their holdings.

NYU surgeon transplants an engineered pig kidney into the outside of a brain-dead patient (Joe Carrotta/NYU Langone Health)

No, sci­en­tists are not any clos­er to pig-to-hu­man trans­plants than they were last week

Steve Holtzman was awoken by a 1 a.m. call from a doctor at Duke University asking if he could put some pigs on a plane and fly them from Ohio to North Carolina that day. A motorcyclist had gotten into a horrific crash, the doctor explained. He believed the pigs’ livers, sutured onto the patient’s skin like an external filter, might be able to tide the young man over until a donor liver became available.

UP­DAT­ED: Agenus calls out FDA for play­ing fa­vorites with Mer­ck, pulls cer­vi­cal can­cer BLA at agen­cy's re­quest

While criticizing the FDA for what may be some favoritism towards Merck, Agenus on Friday officially pulled its accelerated BLA for its anti-PD-1 inhibitor balstilimab as a potential second-line treatment for cervical cancer because of the recent full approval for Merck’s Keytruda in the same indication.

The company said the BLA, which was due for an FDA decision by Dec. 16, was withdrawn “when the window for accelerated approval of balstilimab closed,” thanks to the conversion of Keytruda’s accelerated approval to a full approval four months prior to its PDUFA date.

On­copep­tides stock craters as it pulls can­cer drug Pepax­to from the mar­ket

Shares of Oncopeptides crashed more than 70% in early Friday trading after the company said it’s pulling its multiple myeloma drug Pepaxto (melphalan flufenamide) from the US market after failing a confirmatory trial. The move will force the company to close its US and EU business units and enact significant layoffs.

The FDA had scheduled an adcomm meeting next Thursday to discuss Pepaxto, which first won accelerated approval in February and costs about $19,000 per course of treatment. The committee was to weigh in on whether the confirmatory trial demonstrated a worse overall survival in the treatment arm compared to the control arm.

How to col­lect and sub­mit RWD to win ap­proval for a new drug in­di­ca­tion: FDA spells it out in a long-await­ed guid­ance

Real-world data are messy. There can be differences in the standards used to collect different types of data, differences in terminologies and curation strategies, and even in the way data are exchanged.

While acknowledging this somewhat controlled chaos, the FDA is now explaining how biopharma companies can submit study data derived from real-world data (RWD) sources in applicable regulatory submissions, including new drug indications.

Pfiz­er pitch­es its Covid-19 vac­cine for younger chil­dren ahead of ad­comm next week

Pfizer will present its case to the FDA’s vaccine adcomm next week, seeking authorization for a lower-dose version of its Covid-19 vaccine for kids ages 5 through 12, which the Biden administration said will likely begin rolling out early next month.

Two primary doses of the 10 µg vaccine (the dose for those ages 12 and up is 30 μg) given 3 weeks apart in this group of children “have shown a favorable safety and tolerability profile, robust immune responses against all variants of concern including Delta, and vaccine efficacy of 90.7% against laboratory-confirmed symptomatic COVID-19,” the company said in briefing documents ahead of next Tuesday’s meeting of the FDA’s Vaccines and Related Biological Products Advisory Committee.

Jay Flatley, new Zymergen CEO

Fol­low­ing Au­gust melt­down, Zymer­gen hints at sal­vage plans — cut­ting jobs and rene­go­ti­at­ing loans

Two months after a spectacular implosion that saw its founding CEO leave his post amid customer reports its only product didn’t work, Zymergen provided the first peek behind the curtain for its plans moving forward.

In an SEC filing Wednesday, Zymergen told regulators it would slash about 100 jobs and had renegotiated a $100 million loan from Perceptive that loomed like a storm cloud over the company, moving up the maturity date 18 months to June 30, 2022. Jed Dean, one of Zymergen’s three co-founders and VP of operations, will also step down at the end of the month.

Sanofi, Re­gen­eron etch out an­oth­er PhI­II vic­to­ry for Dupix­ent, eas­ing se­vere itch and clear­ing le­sions

Sanofi and Regeneron can boast of another inflammatory disease where Dupixent has proven effective.

The best-selling drug, which targets both IL-4 and IL-13, has delivered a clean sweep in a Phase III trial for prurigo nodularis, a chronic disease characterized by itch so intense that it can affect patients’ sleep and psychology. Thick skin lesions can cover most of the body.

On the primary endpoint, 37% of patients taking Dupixent saw a clinically meaningful reduction in itch compared to 22% of those on placebo (p=0.0216) at week 12. All secondary endpoints were also met, including clearance of skin lesions and improvement in quality of life.

Pfiz­er throws its weight be­hind LNP play­er eye­ing mR­NA treat­ments for CF, PCD

David Lockhart did not see the meteoric rise of messenger RNA and lipid nanoparticles coming.

Thanks to the worldwide fight against Covid-19, mRNA — the genetic code that can be engineered to turn the body into a mini protein factory — and LNPs, those tiny bubbles of fat carrying those instructions, have found their way into hundreds of millions of people. Within the biotech world, pioneers like Alnylam and Intellia have demonstrated just how versatile LNPs can be as a delivery vehicle for anything from siRNA to CRISPR/Cas9.
