In 'his­toric' pub­lic health step, WHO ful­ly en­dors­es Glax­o­SmithK­line's malar­ia shot

Glax­o­SmithK­line won a big en­dorse­ment from the WHO on Wednes­day.

The or­ga­ni­za­tion has ap­proved the British drug­mak­er’s malar­ia vac­cine for chil­dren, it an­nounced, paving the way for full de­ploy­ment through­out sub-Sa­ha­ran Africa af­ter a pi­lot pro­gram in Ghana, Kenya and Malawi rolled out in 2019. It’s large­ly seen as a huge win in a par­a­sitic dis­ease that kills rough­ly half a mil­lion peo­ple each year, in­clud­ing more than a quar­ter mil­lion chil­dren un­der 5, al­most all of whom live on the African con­ti­nent.

“This is a his­toric mo­ment. The long-await­ed malar­ia vac­cine for chil­dren is a break­through for sci­ence, child health and malar­ia con­trol,” said WHO Di­rec­tor-Gen­er­al Tedros Ad­hanom Ghe­breye­sus in a state­ment. “Us­ing this vac­cine on top of ex­ist­ing tools to pre­vent malar­ia could save tens of thou­sands of young lives each year.”

GSK’s vac­cine was first ap­proved by the EMA in 2015, but didn’t im­press the WHO im­me­di­ate­ly. Con­cerns arose over the shot’s ef­fi­ca­cy, which in clin­i­cal tri­als reached 50% against se­vere malar­ia af­ter the first year but fell to ze­ro two to three years lat­er. Some ex­perts al­so ques­tioned the shot’s abil­i­ty to pre­vent death, giv­en that stud­ies did not di­rect­ly mea­sure mor­tal­i­ty.

The shot must al­so be ad­min­is­tered in four dos­es, be­gin­ning when chil­dren reach five months of age un­til they turn three years old. But cur­rent­ly, the best tools to fight malar­ia have been spray­ing in­sec­ti­cides in the home and wrap­ping mat­tress­es with spe­cial nets to ward off the mos­qui­toes that car­ry the par­a­site.

Rather than ap­prove the shot for wide use, the WHO launched a pi­lot pro­gram in 2019 to ex­am­ine the shot’s ef­fec­tive­ness. Per Wednes­day’s an­nounce­ment, the pro­gram showed that more than two-thirds of chil­dren in the three coun­tries who are not sleep­ing un­der a bed­net are ben­e­fit­ing from the vac­cine, which is known as Mosquir­ix or RTS,S.

The WHO al­so high­light­ed that even in ar­eas where nets are in high use, adding the shot re­duced deaths from se­vere malar­ia by 30%. One out­side mod­el showed the shot will pre­vent more than 5 mil­lion cas­es and 23,000 deaths an­nu­al­ly in chil­dren un­der five in ar­eas with the high­est in­ci­dence rates.

GSK had pre­vi­ous­ly an­nounced plans to pro­vide 10 mil­lion dos­es for use in the pi­lots and will com­mit to 15 mil­lion dos­es an­nu­al­ly now that the shot has been ap­proved for wider use. The Big Phar­ma re­cent­ly shift­ed pro­duc­tion of its vac­cine to Bharat Biotech in In­dia, aim­ing for the biotech to be the sole man­u­fac­tur­er of the shot’s pro­tein by 2029.

There are oth­er malar­ia vac­cines in de­vel­op­ment, but GSK’s shot is the first to gain WHO ap­proval — and the first shot ever OK’ed in any par­a­sitic dis­ease. No­vavax and Ox­ford Uni­ver­si­ty tout­ed a 75% ef­fi­ca­cy in a Phase III study in April, while BioN­Tech is gear­ing up to make an mR­NA-based malar­ia shot fol­low­ing the suc­cess of its Covid-19 vac­cines.

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.

No­vo CEO Lars Fruer­gaard Jør­gensen on R&D risk, the deal strat­e­gy and tar­gets for gen­der di­ver­si­ty

 

I kicked off our European R&D summit last week with a conversation involving Novo Nordisk CEO Lars Fruergaard Jørgensen. Novo is aiming to launch a new era of obesity management with a new approval for semaglutide. And Jørgensen had a lot to say about what comes next in R&D, how they manage risk and gender diversity targets at the trendsetting European pharma giant.

John Carroll: I’m here with Lars Jørgensen, the CEO of Novo Nordisk. Lars, it’s been a really interesting year so far with Novo Nordisk, right? You’ve projected a new era of growing sales. You’ve been able to expand on the GLP-1 franchise that was already well established in diabetes now going into obesity. And I think a tremendous number of people are really interested in how that’s working out. You have forecast a growing amount of sales. We don’t know specifically how that might play out. I know a lot of the analysts have different ideas, how those numbers might play out, but that we are in fact embarking on a new era for Novo Nordisk in terms of what the company’s capable of doing and what it’s able to do and what it wants to do. And I wanted to start off by asking you about obesity in particular. Semaglutide has been approved in the United States for obesity. It’s an area of R&D that’s been very troubled for decades. There have been weight loss drugs that have come along. They’ve attracted a lot of attention, but they haven’t actually ever gained traction in the market. My first question is what’s different this time about obesity? What is different about this drug and why do you expect it to work now whereas previous drugs haven’t?

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.

Renowned Dana-Far­ber sci­en­tist, men­tor and bio­phar­ma ad­vi­sor David Liv­ingston has died

David Livingston, the Dana-Farber/Harvard Med scientist who helped shine a light on some of the key molecular drivers of breast and ovarian cancer, died unexpectedly last Sunday.

One of the senior leaders at Dana-Farber during his nearly half century of work there, Livingston was credited with shedding light on the genes that regulate cell growth, with insights into inherited BRCA1 and BRCA2 mutations that helped lay the scientific foundation for targeted therapies and earlier detection that have transformed the field.

UP­DAT­ED: FDA slaps As­traZeneca's MCL-1 can­cer drug with a hold af­ter safe­ty is­sue — 2 years af­ter Am­gen axed a trou­bled ri­val

There are new questions being posed about a class of cancer drugs in the wake of the second FDA-enforced clinical hold in the field.

Two years after the FDA hit Amgen with a clinical hold on its MCL-1 inhibitor AMG 397 following signs of cardiac toxicity, AstraZeneca says that regulators hit them with a hold on their rival therapy of the same class.

The pharma giant noted on clinicaltrials.gov that its Phase I/II study for the MCL-1 drug AZD5991 “has been put on hold to allow further evaluation of safety related information.”

Sur­geons suc­cess­ful­ly at­tach pig kid­ney to a hu­man for the first time, us­ing tech from Unit­ed's Re­vivi­cor

In a first, researchers reportedly successfully transplanted a pig kidney into a human without triggering an immediate immune response this week. And the technology came from the biotech United Therapeutics.

Surgeons spent three days attaching the kidney to the patient’s blood vessels, but when all was said and done, the kidney appeared to be functioning normally in early testing, Reuters and the New York Times were among those to report. The kidney came from a genetically altered pig developed through United’s Revivicor unit.
