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.

“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.”

Janet Woodcock may have one of the most historically long and drug-intense tenures in FDA history, but her new role is outside of all things pharma and the once-acting FDA commissioner isn’t looking back.

“No I really don’t look back,” Woodcock told Endpoints News via email on Monday morning. “Yes I will be transitioning. Longer discussion on infrastructure needed.”

Pfizer has agreed to pay $290,000 to settle allegations of questionable copay coupon practices in Arizona, Colorado, Kansas, and Vermont from 2014 to 2018.

While the company has not admitted any wrongdoing as part of the settlement, Pfizer has agreed to issue restitution checks to about 5,000 consumers.

A Pfizer spokesperson said the company has “enhanced its co-pay coupons to alleviate the concerns raised by states and agreed to a $30,000 payment to each.”

A judge in Delaware has ruled against Astellas Pharma and Gilead in a long-running patent case over Pfizer-onwed Hospira’s generic version of Lexiscan.

The case kicked off in 2018, after Hospira submitted an Abbreviated New Drug Application (ANDA) for approval to market a generic version of Gilead’s Lexiscan. The drug is used in myocardial perfusion imaging (MPI), a type of nuclear stress test.

The area of Ireland famous for Blarney Castle and its cliffsides along the Atlantic Ocean is seeing Merck KGaA expand its commitment there.

The German drug manufacturer is expanding its membrane and filtration manufacturing capabilities in Ireland. The company will invest approximately €440 million ($470 million) to increase membrane manufacturing capacity in Carrigtwohill, Ireland, and build a new manufacturing facility at Blarney Business Park, in County Cork, Ireland.

Twenty House Democrats, including Reps. Katie Porter of California and Susan Wild of Pennsylvania, are calling on Senate leaders to move quickly with a reconciliation bill (meaning they only need a simple majority for passage) with prescription drug pricing reforms, and to include adding new authority for Medicare to negotiate drug prices.

They also called on the Senate to specifically follow suit with the House passage of a $35 per month insulin cap (as Senate Majority Leader Chuck Schumer’s deadline for a vote on that provision has come and gone), and to cap Medicare Part D costs at $2,000 per year for seniors.

As the cases of monkeypox now sit at well over 100 worldwide and have spread to multiple continents, the orders for any type of vaccine against monkeypox are seeing nations and medical bodies looking to get their hands on anything and everything. And now SIGA Technologies seems to be getting in on the action.

According to Euronews, SIGA Technologies, a pharmaceutical company that is focused on providing medical countermeasures to biological and chemical attacks, is now in talks with several European authorities looking to stockpile its antiviral that can counter monkeypox. The drug known as tecovirimat or Tpoxx was approved by the FDA in 2018 as a vaccine for smallpox but was approved by the European Medicines Agency to also act against monkeypox, cowpox and complications from immunization with vaccinia.

Bristol Myers Squibb is bringing new life to a chemotherapy drug from the old Celgene pipeline as it touts another approval in a rare form of blood cancer affecting young children.

The FDA on Friday approved Vidaza (chemically known as azacitidine) for pediatric patients 1 month and older with newly diagnosed juvenile myelomonocytic leukemia (JMML). The new indication marks the first approval for Vidaza in more than a decade, though it’s commonly used to treat acute myeloid leukemia and myelodysplastic syndromes (MDS).
