With the ris­ing num­ber of mon­key­pox cas­es, lead­ing re­searchers at the CDC, FDA and NIH are call­ing on a ran­dom­ized clin­i­cal tri­al to see if an ap­proved small­pox drug is ef­fec­tive at treat­ing mon­key­pox.

No mon­key­pox treat­ments are ap­proved in the US, so pa­tients look­ing to get re­lief for their le­sions and oth­er symp­toms from the virus must go through a set of hur­dles to get the small­pox drug through a gov­ern­ment ex­pand­ed ac­cess pro­gram. Ap­proved for small­pox in 2018, the drug is mar­ket­ed as TPOXX by the biotech SIGA. The Eu­ro­pean Union ap­proved it for mon­key­pox in ad­di­tion to small­pox ear­li­er this year and the UK fol­lowed suit in Ju­ly.

In an opin­ion piece pub­lished in the New Eng­land Jour­nal of Med­i­cine on Wednes­day, gov­ern­ment re­searchers said the NIH’s Na­tion­al In­sti­tute of Al­ler­gy and In­fec­tious Dis­eases is work­ing with the AIDS Clin­i­cal Tri­als Group, which has over­seen stud­ies of HIV meds since the 1980s, to set up a clin­i­cal tri­al to test TPOXX for mon­key­pox.

But while NI­AID, ACTG and SIGA all con­firmed to End­points News via email that a US-based clin­i­cal tri­al of the drug is be­ing planned, they de­clined to say when it would start. Ac­tivists ar­gue the tri­al should have tak­en place be­fore mon­key­pox be­came a glob­al out­break be­cause the virus has been en­dem­ic in some coun­tries in Africa for years.

“Adults with mon­key­pox in­fec­tion, in­clud­ing peo­ple liv­ing with HIV, would be el­i­gi­ble to en­roll. NI­AID will share more in­for­ma­tion as it be­comes avail­able,” the NI­AID said in an emailed state­ment.

“Those tri­als should have been ob­vi­ous­ly planned for well be­fore a cur­rent out­break. This is what the job of pan­dem­ic pre­pared­ness is. We ob­vi­ous­ly had mil­lions of dos­es stock­piled for this pur­pose and it is in­sane that the fed­er­al gov­ern­ment didn’t ac­tu­al­ly have ef­fi­ca­cy tri­als planned for it,” James Krel­len­stein, strat­e­gy & pol­i­cy man­ag­ing di­rec­tor for the or­ga­ni­za­tion PrEP4All, told End­points in a phone in­ter­view.

The re­searchers analo­gize the lack of ap­proved meds for the cur­rent mon­key­pox out­break to the ear­ly years of the HIV epi­dem­ic in the 1980s, when ther­a­pies had been de­vel­oped, but the process for ap­prov­ing their use in hu­mans was “painful­ly slow.” An eth­i­cal bal­ance was need­ed to en­sure pa­tients had ac­cess while al­so “up­hold­ing the re­spon­si­bil­i­ty” of en­sur­ing they were safe and ef­fec­tive, the re­searchers wrote Wednes­day in NE­JM.

“Now, 34 years lat­er, we are faced with an un­can­ni­ly sim­i­lar sit­u­a­tion,” they wrote. The au­thors of the piece in­clude John Brooks, CMO for the CDC’s Di­vi­sion of HIV Pre­ven­tion; De­bra Birnkrant, di­rec­tor of the Di­vi­sion of An­tivi­rals with­in the FDA’s Cen­ter for Drug Eval­u­a­tion and Re­search; and Pe­ter Kim, deputy di­rec­tor of the Ther­a­peu­tic Re­search Pro­gram in the Di­vi­sion of AIDS at NI­AID.

Or­ga­ni­za­tions such as PrEP4All have called for the re­moval of re­stric­tions to the drug so pa­tients can get the med quick­er and more eas­i­ly as mon­key­pox case counts climb past 25,000 across 83 coun­tries. The US is one of the biggest out­break re­gions and three states — Illi­nois, New York and Cal­i­for­nia — have de­clared it a pub­lic health emer­gency.

Pri­or to the cur­rent glob­al out­break, the NIH had be­gun plan­ning for a ran­dom­ized clin­i­cal tri­al of the drug in the De­mo­c­ra­t­ic Re­pub­lic of the Con­go, but in their NE­JM piece, the re­searchers cite the need for a US-based tri­al since cur­rent world­wide cas­es are of a dif­fer­ent clade than what is seen in the DRC.

The US has ac­cess to about 1.7 mil­lion cours­es of the drug through the Strate­gic Na­tion­al Stock­pile, and BAR­DA has a con­tract with SIGA to re­plen­ish the cours­es when they ex­pire, ac­cord­ing to the com­pa­ny. As of last week, 10,000 cours­es of the drug had been sent to states and cities up­on re­quest, the De­part­ment of Health and Hu­man Ser­vices told NPR.

A SIGA spokesper­son said the com­pa­ny is “aware of the plans for a clin­i­cal tri­al and is work­ing with NI­IAD [sic] to ad­vance a place­bo-con­trolled study of tecovir­i­mat in the treat­ment of mon­key­pox.” SIGA re­ports quar­ter­ly earn­ings on Thurs­day.

SIGA can­celed a sched­uled in­ter­view be­tween sci­ence chief Den­nis Hru­by, CEO Phillip Gomez and End­points, say­ing that it “would pre­fer to wait for pub­li­ca­tion of the full ar­ti­cle in NE­JM be­fore com­ment­ing much fur­ther on any specifics.”

Hru­by told NBC News last month that plans for large clin­i­cal tri­als were in ad­vanced stages in Cana­da, the UK and the EU. Hru­by told the news out­let that SIGA might not re­ly on US tri­al da­ta to sub­mit to the FDA, but rather look to com­bined find­ings in oth­er coun­tries and safe­ty da­ta from glob­al com­pas­sion­ate-use pro­grams.

In their NE­JM piece, the CDC, FDA and NIH re­searchers wrote that they “an­tic­i­pate that these tri­als will pro­vide da­ta need­ed for clin­i­cal and reg­u­la­to­ry de­ci­sion mak­ing in the Unit­ed States.”

SIGA’s drug was ap­proved in the US in 2018 un­der the “An­i­mal Rule,” which al­lows drugs for se­ri­ous or life-threat­en­ing con­di­tions to be green­lit when hu­man stud­ies are deemed un­eth­i­cal. Ef­fi­ca­cy is es­tab­lished in an­i­mal mod­els of the hu­man dis­ease. The drug was ap­proved based on ef­fi­ca­cy da­ta gath­ered from in­fect­ing non­hu­man pri­mates with mon­key­pox virus and rab­bits with rab­bit­pox virus, as well as safe­ty da­ta from more than 400 healthy adult vol­un­teers.

As the mon­key­pox out­break spreads to more than 6,000 re­port­ed cas­es in the US, peo­ple at high­est risk have been scram­bling to get vac­ci­nat­ed against the virus. There is one jab ap­proved in the US, Bavar­i­an Nordic’s Jyn­neos, which is in lim­it­ed sup­plies in the US af­ter a na­tion­al stock­pile large­ly evap­o­rat­ed in re­cent years. A small­pox vac­cine, ACAM2000, is al­so be­ing used in cer­tain in­stances.

Mean­while, Mod­er­na lead­ers said Wednes­day that the pan­dem­ic-in­fa­mous biotech is look­ing in­to a po­ten­tial mon­key­pox pro­gram.

What’s Biohaven without its CGRP portfolio? That’s what CEO Vlad Coric is tasked with deciding as he maps out the new Biohaven post-Pfizer takeover.

Pfizer officially scooped up Biohaven’s CGRP assets on Monday, including blockbuster migraine drug Nurtec and the investigational zavegepant, for $11.6 billion. As a result, Coric spun the broader pipeline into an independent company on Tuesday — with the same R&D team behind Nurtec but about 1,000 fewer staffers and a renewed focus on neuroscience and rare disease.

There are some odd-looking purple creatures lurking around the halls of AstraZenca lately. The “Phil” character cutouts are purple, personified eosinophils with big buggy eyes and wide mouths, and they’re a part of AZ’s newest awareness effort to help people understand eosinophilic asthma.

The “Asthma Behaving Badly” characters aren’t only on the walls at AZ to show the new campaign to employees, however. The “Phils” are also showing up online on the campaign website, and in digital and social ads and posts on Facebook and Instagram.
