Ebola outrunning its tools

High ↑

Africa's disease agency counts 10,444 confirmed cases and more than 5,300 deaths. [3] A British health worker caught the virus in Congo and is being flown home. [8] Results from the vaccine trial are not due until early 2027. [1]

What is moving · 2 of 4

Drugmakers buying early medicines

Building ↑

Boehringer Ingelheim, a German drugmaker, agreed $358 million in early payments for 6 cancer projects still in the lab. [12] AbbVie, a big US drugmaker, is paying $100 million for a gut drug that Nxera had stepped back from. [14]

What is moving · 3 of 4

Failed tests forcing cuts

High →

Ultragenyx, a rare-disease drugmaker, is cutting 20% of its staff after failed trials. [17] Sanofi dropped an eczema pill from Nurix, whose shares fell more than 40%. [16]

What is moving · 4 of 4

Hopes resting on tiny trials

Steady →

Kamau's gene repair for sickle cell disease has results from 3 patients. [15] A melanoma cell treatment shrank tumours in 10 of 15 patients at its chosen dose. [26] A gut-bacteria treatment's result comes from 34 transplant patients. [25]

WHO's advisers back 2 vaccines built for the Ebola strain that has killed over 5,300, for a trial in Congo

Swipe up for the story ↑Scroll down for the story ↓

Experts advising the World Health Organization (WHO) want 2 new vaccines added to an Ebola trial in Congo. [1] Both were built for Bundibugyo, the kind of Ebola now spreading there. [1]

The outbreak has killed more than 5,300 people, most of them in Congo. [3] No vaccine is approved against Bundibugyo. [4]

a first test during an outbreak

This will be the first time vaccines made for this virus are tested during an outbreak of it. [1]

Africa's disease agency counts 10,444 confirmed cases. [3] It says more than half of those infected have died. [3]

Who is involved

Who is involved

Why it matters

WHO's chief, Tedros Adhanom Ghebreyesus, says vaccines cannot replace early care, contact tracing, isolation and safe burials. [3]

Why it matters

travel limits on people from Congo

He also asked countries such as the US and Ghana to lift travel limits. [4] He says they punish countries for doing right and discourage openness. [4]

How it works

Epidemiologists, who study how disease spreads, call Tumaini's design ring vaccination: it enrols the contacts of each confirmed patient. [1]

How it works

4 of 4

rings in place so far

Tumaini has 4 rings so far, including contacts of people who fell ill or died. [1] The same approach proved Ervebo in Guinea a decade ago. [1]

How it works

It tests several vaccines inside one trial, which is how Oxford's and Moderna's shots can join it. [1]

Seen it before

the nearest houses first

A firefighter wets the houses next to a fire, not every house in town.

The truth

So far, tests in people have measured safety and immune response, not protection from Ebola. [2]

The truth

rare risks seen with the Covid versions

Oxford's and Moderna's Covid vaccines were linked to rare blood clots and heart inflammation. [2] The advisers said nobody knows if those risks apply here. [2]

What comes next

results in early 2027

WHO expects results from the vaccine trial in early 2027. [1]

What's really going on

WHO's advisers have chosen 2 vaccines built for Bundibugyo, but more than 5,300 people have died and the trial's results are not due until early 2027.

What's really going on

Elsewhere, the work of finding and selling medicines moved between companies: Boehringer and AbbVie bought early drugs, Ultragenyx cut its own research, and CVS is splitting its shops from its insurer. [1][3][10][13][14][17]

Who pays

They work in a conflict zone without a proven vaccine, and a nurse was killed responding to an alert. [6]

Who pays

Travel limits by countries such as the US and Ghana fall on them, against WHO's advice. [4]

Nobody knows yet

Whether either new vaccine protects people from Bundibugyo.

Tests in people so far have measured safety and immune response, and WHO expects trial results only in early 2027. [1][2]

Nobody knows yet

How many people have died in Congo.

Africa's disease agency counted 5,372 deaths in Congo on Monday, while Congo's own data to 31 October shows 5,103. Neither report explains the gap. [5][4]

Nobody knows yet

How deadly this outbreak really is.

The BBC reported a death rate of 48.6% at the end of October, while Euronews and Africanews say more than 50%. [7][3][5]

Nobody knows yet

When Congo will approve the 2 new vaccines.

WHO says they join the trial after national approvals and names no date. [1]

Good news

Two vaccines built for the Bundibugyo kind of Ebola will be tested during an outbreak of it for the first time, and WHO's advisers were unanimous in backing them.

Part 2 of 6 · How it unfolded

Part 3 of 6

Ervebo, made for another kind of Ebola

The trial, called Tumaini, began last month with Ervebo, a vaccine approved only for another kind of Ebola. [1][3]

Part 3 of 6

WHO's vaccine advisers met 4 times between 1 September and 2 November. [2] Members were unanimous: add both vaccines. [2]

Part 3 of 6

risk against benefit: favourable

The advisers called the data so far extremely encouraging. [2] Given how severe the outbreak is, they judged the balance of risk and benefit very favourable. [2]

Part 3 of 6

Congo's approval still to come

Both vaccines still need approval from Congo's authorities before they can join the trial. [1][7]

Part 4 of 6

Oxford's shot is made by the Serum Institute of India, which has about 620,000 doses of vaccine material. [2] It still has to be processed into finished vaccine. [2]

Part 4 of 6

Moderna, the US maker of mRNA vaccines, has made about 12,000 vials, due to be ready by mid-November. [2] It expects 1 million more doses by the second quarter of 2027. [2]

Part 4 of 6

The trial is led by Congo's National Institute for Biomedical Research. [1] WHO, Doctors Without Borders and Africa's disease agency are among those supporting it. [1]

Part 5 of 6

A small animal test: the gap is why advisers took the shot further.

In a test on ferrets, all 4 given Oxford's shot survived and all 4 unvaccinated animals died. [2]

Part 5 of 6

In macaques, a kind of monkey, 2 of 12 given Oxford's shot died. [2] All the primates in Moderna's test survived. [2]

Part 5 of 6

mostly mild or moderate reactions

Early safety trials in adults in the UK and Canada found mostly mild or moderate reactions. [2]

Part 6 of 6

treatments in a second trial

A separate WHO trial, PARTNERS, is testing the antibody MBP134 and the antiviral remdesivir in patients. [1] First findings are expected in the coming months. [1]

A British health worker with Ebola flies home

Swipe up for the story ↑Scroll down for the story ↓

A British health worker with Ebola is being flown from Congo to Britain, a document seen by Reuters shows. [8]

“the risk to the UK public from Ebola remains low”
UK government

The UK government confirmed that a British citizen in Congo has tested positive. [7] It says "the risk to the UK public from Ebola remains low". [7]

Who is involved

stable, on the way to care

A humanitarian group had sent the person to help fight the outbreak. [8] The patient's condition is stable. [8]

A specialist ambulance will take the patient to a unit for high-risk infections. [8]

How it got here

It is the first British case in this outbreak. [7] Britain has had only 4 confirmed cases since 1976, and none of them died. [7]

How it got here

Switzerland flew out a patient from Nigeria last month, and France reported a case in June. [8]

Why it matters

The people sent to help are among those catching it. [8] France's first case was a doctor back from a humanitarian mission. [8]

How it works

Epidemiologists call this contact tracing: people with Ebola infect others only once they have symptoms, so contacts can be found. [9]

How it works

When a person can pass the virus on: this is why tracing works better against Ebola.

Ebola passes through body fluids, with no evidence of spreading by coughing. [9] Covid could spread before people knew they were ill. [9]

Seen it before

wet paint: see it, avoid it

A wet paint sign works because you can see the paint and avoid touching it.

The truth

no name, and questions passed on

The patient's name was not given. [8] WHO sent Reuters' questions about the case to British authorities. [8]

CVS will split into two companies

Swipe up for the story ↑Scroll down for the story ↓

CVS Health, a US health giant, said on Wednesday it will split into two companies. [10] It expects the split to finish in the first half of 2028. [10]

Who is involved

One company keeps the name CVS Health, with its insurer Aetna and its drug middleman, Caremark. [10] The other, CVS Pharmacy, takes the 9,000 shops. [10]

Who is involved

Caremark, a drug-price middleman

Caremark is a pharmacy benefit manager, or PBM: a middleman on drug prices between drugmakers and health plans. [10]

How it got here

CVS bought Caremark in 2007 and Aetna in 2018, the second in a $78 billion merger. [10]

It made a $2.2 billion profit last quarter, after a $4 billion loss a year earlier. [10] Its chief says it is acting "from a position of strength". [10]

Why it matters

Arkansas and Tennessee have laws that would stop one owner holding both pharmacies and PBMs, and CVS is challenging them. [10]

Why it matters

a shop chain standing alone

CVS Pharmacy will have to stand alone in a trade where some chains have gone private or bankrupt. [10]

How it works

Economists call owning several steps of a chain vertical integration, and CVS built it by buying Caremark and Aetna. [10]

How it works

CVS's chief says what the shops and the insurer share can be kept through contracts. [10] So, he says, they need no single owner. [10]

Seen it before

same bread, new owner

A cafe that sells off its bakery can still buy the same bread from it each morning.

The truth

CVS's chief says regulators are not the reason for the split. [10] A Leerink analyst says avoiding state scrutiny could be part of it. [10]

How it works

Why a company does some jobs itself and buys the rest

How it works

Economists call it the make-or-buy choice: a firm does a job itself only while that costs less than paying someone outside.

How it works · step 1 of 5

Ronald Coase, an economist, asked in 1937 why companies exist, when every job could be bought from outside

How it works · step 2 of 5

Buying has costs: finding a seller, agreeing a price, checking the work

How it works · step 3 of 5

Doing it inside has costs too: bosses, staff and work that may fail

How it works · step 4 of 5

The company picks whichever costs less for that one job

How it works · step 5 of 5

When those costs change, the line moves: firms buy in, or split up

The twist

A company is a line drawn around the jobs that cost less to do inside than to buy. Today that line moved at CVS, Boehringer, AbbVie and Ultragenyx.

The picture

Each way of getting a job done has its own bill. A company compares the two, one job at a time.

Seen the same day

CVS will split into two companies

CVS's chief says what the shops and the insurer share can be kept by contract, so the company no longer needs to own both.

Seen the same day

Boehringer pays for six early cancer projects

Boehringer pays Sino to run the early work on 6 projects, then decides which to license, instead of doing that work itself.

Seen the same day

AbbVie buys a gut drug Nxera stepped back from

Nxera's chief called IBD too complex and expensive to develop, so the work moved to a firm that already sells IBD drugs.

Seen the same day

Ultragenyx cuts a fifth of its staff

Ultragenyx is halving its research spending and will fill its pipeline partly with small deals, moving some of the job outside.

The catch

Real firms rarely do these sums cleanly: they misjudge their own costs, and laws can move the line as much as prices do, as Arkansas and Tennessee are trying to do with CVS.

The whole

A person collecting a prescription sees one shop and one pill.

The whole

Behind them sit a lab in China, a drugmaker in Germany, a middleman and an insurer, each doing the part it finds cheapest, and none of them can see the whole chain from where it sits.

Who pays

It loses a parent with an insurer behind it, in a trade where other chains went bankrupt. [10]

The Wegovy pill lifts Novo's forecast

Swipe up for the story ↑Scroll down for the story ↓

Novo Nordisk, the Danish maker of the weight-loss drug Wegovy, raised its yearly forecast on Wednesday. [11] Adjusted for currency swings, sales and profit may now grow as much as 2%. [11]

In May, the best case the company gave was a 4% drop. [11]

Its Wegovy pill, on sale since January, brought in 5.39 billion Danish kroner, about $811 million, last quarter. [11] Analysts had expected 4.96 billion. [11]

Foundayo, the rival pill from Eli Lilly, reached $184 million, which was $44 million short of estimates. [11]

How it got here

two-thirds of its value gone

Novo has lost about two-thirds of its value since June 2024. [11] Its next shot, CagriSema, failed a trial against Lilly's Zepbound. [11]

Who is involved

a new finance chief

Finance chief Karsten Munk Knudsen is leaving, and Luigi La Corte of Galderma, a skin-care drug company, will replace him. [11]

Why it matters

63 of 100

of the US market, Lilly claims

Patents on Wegovy's main ingredient end several years before those on Lilly's rival drugs. [11] Lilly already claims 63% of the US market for these medicines. [11]

How it works

Business schools call this a first-mover advantage: Novo's January pill is outselling Lilly's April pill so far. [11]

Seen it before

first van, longest queue

The first ice cream van on the street gets the queue, until a better one turns up.

Who gains

An early lead in pills gives it income while its older patents run down. [11]

Boehringer pays for six early cancer projects

Swipe up for the story ↑Scroll down for the story ↓

Boehringer Ingelheim, a German drugmaker, agreed on Wednesday to $358 million in early payments to China's Sino Biopharmaceutical. [12][13]

6 of 6

cancer projects, none yet in people

The money covers 6 cancer projects, all still at the preclinical stage, before any human trial. [12]

Sino could earn up to $7 billion more if the drugs keep advancing, plus a share of any sales. [13]

Sino runs the early work up to agreed points. [13] Boehringer then chooses whether to pay more for a licence. [13]

2 of 6

projects with worldwide rights on offer

Boehringer could buy worldwide rights to 2 of the drugs and rights outside China to the other 4. [13]

Who is involved

Sino's LaNova Medicines unit made 5 of the projects, and its Beijing Tide Pharmaceutical unit made 1. [13] This is the second partnership between the two companies. [12]

Why it matters

a closer look at China deals

US lawmakers may look harder at the surge in drug deals with China, BioPharma Dive reports. [20] RBC's analysts do not expect a ban on company deals. [20]

How it works

Lawyers call this an option: Boehringer pays now for the right to license each drug later. [13]

How it works

pay only for the ones it picks

Boehringer keeps that choice until the early tests report, so it pays licence fees only for drugs it picks. [13]

Seen it before

a deposit holds the flat

A small deposit holds a flat while you decide, and walking away costs only the deposit.

How it works

Boehringer pays for six early cancer projects

Boehringer pays Sino to run the early work on 6 projects, then decides which to license, instead of doing that work itself.

The idea, in story 3: Why a company does some jobs itself and buys the rest →

Who gains

It can wait for Sino's early tests before paying licence fees, so projects it does not pick cost it no fee. [13]

Who gains

It takes in money now while keeping the running of early work, and keeps China rights on 4 of the 6 projects. [12][13]

Gene repair shows early results in sickle cell

Swipe up for the story ↑Scroll down for the story ↓

a repaired gene

Kamau Therapeutics, a California biotech, released its first results from repairing the gene fault behind sickle cell disease. [15]

Who is involved

In sickle cell disease, a faulty gene makes bad haemoglobin, the blood protein that delivers oxygen. [15]

Doctors repaired the fault in 3 patients' own stem cells outside the body, then gave the cells back. [15]

3 of 3

patients with no pain crises since

All 3 no longer need blood transfusions and have had no pain crises since, Kamau reports. [15]

After 12 and 8 months, sickle haemoglobin in the 2 longest-followed patients was 17.6% and 19.1%, both below 20%. [15]

How it got here

The treatment, nula-cel, began at Graphite Bio, which halted its trial in late 2022 and later disbanded. [15]

Why it matters

a tiny share treated so far

Few people with the disease have had the approved gene treatments so far, Kamau's co-founder says. [15]

How it works

Geneticists call this homology-directed repair: the cell swaps its faulty DNA for a healthy copy, as nula-cel does. [15]

How it works

Two treatments for one disease: whether one is better is still a major question.

Casgevy, already approved, works differently: it switches on baby haemoglobin instead of replacing the fault. [15]

Seen it before

fix the master copy

Correcting a typo in the master copy beats sticking a note beside it.

The truth

3 of 15

of about 15 planned patients reported

This is an early-stage trial with 3 patients so far, of some 15 planned. [15] Some serious side effects fit the strong chemotherapy and transplant given first. [15]

Good news

no serious harm from the cells

No serious side effects were tied to the repaired cells themselves. [15]

What comes next

14 December, New Orleans

The results will be presented on 14 December in New Orleans, at a meeting of blood specialists called ASH. [15]

Nobody knows yet

Whether repairing the sickle cell gene beats Casgevy, the approved treatment.

Kamau's co-founder believes it may. The journal GEN calls that a major question, and only 3 patients are reported. [15]

Good news

Three sickle cell patients who had the gene fault repaired in their own stem cells no longer need blood transfusions and have had no pain crises since.

US voters hand health oversight to Democrats

both chambers of the US Congress

Democrats won both chambers of the US Congress on Tuesday, which changes who can question US health officials. [19]

“Subpoenas”
Ron Wyden

Ron Wyden, a Democratic senator who leads on health, posted one word that night: "Subpoenas". [19] A subpoena is a legal order to appear or hand over papers. [19]

Who is involved

Annie Andrews, a children's doctor, won a South Carolina seat in the US Senate. [19] Democrats have not had a senator with a medical degree since 1969. [19]

a founder of the caucus loses

Roger Marshall, a Kansas senator who helped found the Make America Healthy Again caucus, lost his seat. [19]

Why it matters

more questions on vaccine policy

Analysts expect closer questions for US health secretary Robert Kennedy Jr, whose moves weakened vaccine recommendations. [20]

Why it matters

“bigger fish to fry”
David Risinger, Leerink Partners

One Leerink analyst says Democrats have "bigger fish to fry" than drug prices for now. [20]

Why it matters

“It's a new day in Washington”
Gretchen Goldman

Science advocates want answers for cuts to research grants. [21] "It's a new day in Washington," says Gretchen Goldman, head of the Union of Concerned Scientists. [21]

How it works

Political scientists call this oversight: the party holding Congress can investigate officials, which is what Wyden's word points to. [19]

Seen it before

a new treasurer asks for receipts

A new club treasurer can ask to see the old treasurer's receipts.

What comes next

Heidi Overton, President Trump's pick to run the FDA, the US drug regulator, still needs a US Senate vote. [20] Her nomination might expire if none comes this year. [20]

Who gains

Winning Congress gives Democrats powerful new tools to investigate US health decisions. [19]

Nobody knows yet

Whether Democrats will change US drug or vaccine rules.

Analysts expect closer questions on vaccine policy, and one says drug prices can wait. No law or subpoena has yet been reported. [20][19]

Ultragenyx cuts a fifth of its staff

Swipe up for the story ↑Scroll down for the story ↓

20 of 100

of staff being laid off

Ultragenyx, a US drugmaker for rare diseases, is laying off 20% of its staff. [17] About 1,000 people will remain. [17]

It wants yearly research spending at half of what it spent in 2025, with $350 million proposed for 2027. [17]

UX701 stopped

It is ending UX701, a gene therapy for Wilson disease, an inherited illness, because too few patients did well enough. [17]

GTX-102 stopped

It is also winding down GTX-102 after a final trial failed in September in Angelman syndrome, a rare brain disorder. [17]

How it got here

Ultragenyx already cut 10% of its staff, about 130 people, in February. [17] It wants to make a profit in 2027. [17]

Why it matters

6 of 6

drugs already on sale

Most of the money left will support 6 drugs it already sells. [17] Its chief plans about 5 projects a year, from modest lab work and small deals. [17]

How it works

Statisticians call it noise: Ultragenyx's chief says scores in the untreated group varied too much to show an effect. [17]

Seen it before

one whisper in a noisy room

In a noisy classroom you cannot hear whether one person has started whispering.

The truth

the data not yet shared

Ultragenyx has not yet shared the data from that failed trial. [17]

How it works

A former executive sues Madrigal over safety

Swipe up for the story ↑Scroll down for the story ↓

A former top executive is suing Madrigal Pharmaceuticals in a US federal court. [18] He says he was forced to resign after raising safety concerns about its approved drug. [18]

Who is involved

Michael Charlton, a doctor, led clinical development at Madrigal from October 2024 until January 2026. [18]

Who is involved

a drug for a liver disease

The drug treats MASH, a liver disease. [18]

filed 9 October, northern Illinois

The suit was filed on 9 October in northern Illinois. [18] It seeks his job back or money. [18]

“Madrigal punished him for it”
Charlton's lawsuit

"Madrigal punished him for it," the lawsuit says. [18]

Why it matters

safeguarding the trials

Charlton's job was to safeguard the safety and accuracy of the drug's trials, the suit says. [18]

How it works

Employment lawyers call this retaliation: punishing a worker for raising a problem, which US whistleblower laws forbid and Charlton alleges. [18]

Seen it before

reporting should not bring punishment

A pupil who reports a broken fire door should not get detention for it.

The truth

These are one side's claims in a lawsuit. [18] We could read only the opening of this report, and saw no reply from Madrigal. [18]

Nobody knows yet

Whether Madrigal's drug has the safety problem the suit describes.

The claim comes from a former executive's lawsuit, untested in court, and we could read only the opening of the report. [18]

Sanofi drops an eczema pill from Nurix

Swipe up for the story ↑Scroll down for the story ↓

SAR448272 stopped

Sanofi, the big drugmaker behind the eczema drug Dupixent, has stopped work on a pill from Nurix, a biotech. [16]

Nurix revealed the decision on Tuesday. [16] Its shares fell more than 40% in early trading on Wednesday. [16]

“emerging nonclinical findings”
Sanofi, to Leerink Partners

Sanofi told analysts that "emerging nonclinical findings" did not justify more work in eczema. [16] Nonclinical means lab and animal tests, not patients. [16]

How it got here

The partnership began in 2020, with $55 million up front and possibly $2.5 billion overall. [16] Nurix got $10 million in August, when a first human trial began. [16]

Why it matters

People with eczema lose one possible pill. [16] Sanofi still has a second STAT6 project, with Recludix Pharma. [16]

How it works

Chemists call a drug like this a protein degrader: it destroys a protein rather than blocking it. [16]

How it works

STAT6, hard to block

The target, STAT6, plays a part in a misdirected immune response, and small drugs have struggled to block it. [16] So companies tried destroying it instead. [16]

Seen it before

hold the button, or remove the toy

You can hold down a noisy toy's button, or you can take the toy away.

The truth

RBC's analyst called the decision disappointing. [16] Leerink's says it does not count against other drugs aimed at STAT6. [16]

What comes next

Kymera's result, later this year

Kymera, another protein-degrader company, reports a mid-stage trial of a similar drug later this year. [16]

Who pays

They carry the fall, since Sanofi's next payments will not come. [16]

Nobody knows yet

What Sanofi found in its eczema pill.

Nurix gave no reason, and Sanofi told analysts only of emerging nonclinical findings. [16]

AbbVie buys a gut drug Nxera stepped back from

Swipe up for the story ↑Scroll down for the story ↓

AbbVie, the drug giant behind Humira and Skyrizi, will pay $100 million up front for a gut drug from Nxera. [14]

It may pay up to $1.37 billion more as the drug advances and sells, plus a share of sales. [14]

Who is involved

NXE0033744, one human trial so far

The drug, NXE0033744, is a pill for inflammatory bowel disease, or IBD, in which the gut stays inflamed. [14] It has finished only a first human trial. [14]

How it got here

Nxera, a drug company once called Sosei, pulled back from this project late last year while cutting staff. [14]

How it got here

“very, very complex and expensive”
Christopher Cargill, Nxera's chief

Its chief called IBD a "very, very complex and expensive" area in which to develop a drug. [14]

Why it matters

AbbVie already sells Humira, Skyrizi and Rinvoq for IBD. [14] Nxera pitches the new drug at people whose disease is not well controlled. [14]

How it works

Pharmacologists call such a drug gut-restricted, and Nxera says its first trial found this one stays in the gut. [14]

How it works

It switches on a receptor called EP4 in the gut, hoping to calm swelling and heal the lining. [14]

Seen it before

one plant watered

A hose aimed at one plant leaves the rest of the garden dry.

The truth

does it help people?

Nxera's chief says AbbVie must now find out whether this biology really helps people with IBD. [14]

How it works

AbbVie buys a gut drug Nxera stepped back from

Nxera's chief called IBD too complex and expensive to develop, so the work moved to a firm that already sells IBD drugs.

The idea, in story 3: Why a company does some jobs itself and buys the rest →

Who gains

It turns a project it had stepped back from into cash, and it no longer pays to develop it. [14]

FDA speeds its review of a chemo-free cancer pair

Swipe up for the story ↑Scroll down for the story ↓

FDA priority review

The FDA, the US drug regulator, gave a fast review to BeOne Medicines' blood cancer pill, Brukinsa. [23]

Who is involved

BeOne is a cancer drug company. [23] It wants Brukinsa with an antibody drug, rituximab, as first treatment for mantle cell lymphoma, a blood cancer. [23]

What the FDA will weigh: the same antibody, with or without chemotherapy.

Today's usual first treatment is rituximab with bendamustine, a chemotherapy, which brings toxic side effects, BeOne says. [23]

A final trial, MANGROVE, enrolled 510 patients across 157 sites. [23] Risk of the cancer worsening, or death, was 43% lower on Brukinsa's pair. [23]

Why it matters

no chemotherapy, if approved

If approved, it would be the first chemotherapy-free option of this kind for these patients, BeOne says. [23]

How it works

Cancer doctors call it progression-free survival: the time until the cancer worsens or the patient dies, which MANGROVE measured. [23]

How it works

living longer is not yet shown

Overall survival is a separate goal in MANGROVE, so this result does not yet show that patients live longer. [23]

Seen it before

timed to the first stumble

A runner can be timed to her first stumble, and that says little about the finish.

The truth

All this comes from BeOne's own announcement. [23] The trial was open-label: patients and doctors knew the treatment. [23]

What comes next

Full results are due at the ASH meeting of blood specialists. [23] Regulators in China and Europe are also reviewing it. [23]

Guinea-Bissau may give the baby vaccine sooner

Swipe up for the story ↑Scroll down for the story ↓

Guinea-Bissau, a small West African country, may start giving hepatitis B vaccine at birth early next year, not in 2028. [22]

Who is involved

Walter Kazadi Mulombo, WHO's representative there, told the BBC that officials are considering the change. [22]

first dose at 6 weeks

Babies there now get their first dose at 6 weeks, which works less well. [22]

nearly a fifth infected

Nearly a fifth of the people there have hepatitis B, a viral infection of the liver. [22]

How it got here

1 of 2

babies, half without the birth dose

A US-funded trial would have kept the birth dose from half of 14,000 newborns. [22] It has been cancelled. [22]

Why it matters

25 of 100

chronic infections that end in death, at most

Infection in infancy often lasts for life. [22] Those long-lasting infections kill up to 25% of the people who have them, mostly through liver failure or cancer. [22]

How it works

Research ethics says a trial should not withhold a proven treatment, and that was WHO's objection here. [22] The vaccine has been used for over 30 years. [22]

Seen it before

no helmet is no test

A coach would not test a new helmet by sending half the team out with none.

The truth

The university behind the trial says it never started and no baby was enrolled. [22] Police have not said why they seized vaccines there on 19 October. [22]

Good news

the birth dose brought forward

WHO says it is working with the government to bring the birth dose forward. [22]

Good news

Guinea-Bissau is considering giving hepatitis B vaccine to newborns early next year instead of in 2028.

Swallowed gut bacteria cut infections after transplants

Swipe up for the story ↑Scroll down for the story ↓

16 of 16

strains of bacteria in one treatment

A swallowed mix of 16 strains of gut bacteria, SER-155, was tested in people getting donor stem cells. [25]

Who is involved

Doctors do such transplants about 40,000 times a year, aiming to cure blood cancers. [25]

Bloodstream infections hit 10% of those on the treatment and 43% of those on a dummy. [25]

Only 34 people in the comparison had a transplant: 20 on the treatment and 14 on the dummy. [25]

This was a phase 1b trial, an early test of safety. [25] Other goals, such as gut infections, showed no clear gain. [25]

safe so far, in few people

The treatment was as safe as the dummy in this trial, and it caused no infections of its own. [25]

Why it matters

These patients are at high risk of bloodstream infections, and such infections are a main danger after the transplant. [25]

How it works

Microbiologists call it engraftment when added bacteria settle in the gut, and all 16 strains in SER-155 did. [25]

How it works

The transplant disturbs gut bacteria and weakens the gut wall, which raises the risk of blood infection. [25] The treatment aims to repair that. [25]

Seen it before

thick grass, few weeds

A lawn thick with grass leaves little room for weeds.

The truth

8 people died during the study, including 2 on the treatment and 2 on the dummy in this comparison. [25] None of the deaths was blamed on the treatment. [25]

Nobody knows yet

Whether SER-155 really cuts bloodstream infections.

In 34 people the statistical range runs from a huge cut to no effect, and the treated group also had an antibiotic first. [25]

Good news

In a small early trial, 10% of transplant patients on a swallowed dose of gut bacteria got a bloodstream infection, against 43% on a dummy.

A cell treatment doctors can dial up shrinks melanoma

Swipe up for the story ↑Scroll down for the story ↓

Doctors gave a cell treatment, amsoki-cel, to 37 people with advanced melanoma that immune drugs had failed to stop. [26]

10 of 15

patients whose tumours shrank

Tumours shrank in 10 of the 15 patients given the chosen dose, and disappeared in 2 of them. [26]

Who is involved

It is made from immune cells called TILs, taken from the patient's tumour and given back. [26] Melanoma is a skin cancer. [26]

How it got here

The first patient had swelling around a tumour in the brain, so doctors cut the top dose by 80%. [26]

no intensive care needed

No patient died from the treatment, and none needed intensive care. [26] Most serious side effects were low blood counts. [26]

Why it matters

These patients' melanoma has outlasted immune drugs. [26] This treatment is built to skip IL-2, an extra immune signal, which such therapies have needed. [26]

How it works

Cell engineers call this regulatable: the cells' growth signal, IL-15, is controlled by a second drug, acetazolamide. [26]

How it works

After the first patient, doctors also cut that second drug's dose by 75%. [26]

Seen it before

a dimmer, not a plain switch

A dimmer lets you set a lamp's brightness, where a plain switch gives you only on or off.

The truth

  1. 1low end38%
  2. 2high end88%

These trials had no comparison group. [26] With so few patients, the true rate could lie anywhere from 38% to 88%. [26]

What comes next

the deciding group is still running

A separate group in the same trial, meant to support approval, is still running. [26]

An HIV antibody works, then resistant virus gets through

Swipe up for the story ↑Scroll down for the story ↓

VRC01, an antibody given by drip

Researchers looked again at 2 trials of VRC01, an antibody given by drip to prevent HIV. [27]

The trials ran in the Americas and sub-Saharan Africa, with infusions for 80 weeks. [27] The new analysis is in Science Translational Medicine. [27]

Against the virus strains most sensitive to it, the antibody prevented 66.3% of infections. [27]

As the antibody faded after the last doses, HIV diagnoses in the antibody groups rose above the dummy group. [27] Those viruses resisted it more. [27]

Why it matters

those who cannot use the pills

It could matter most for people who cannot use prevention pills, and in high-HIV parts of sub-Saharan Africa. [27]

Why it matters

The authors say several antibodies together will probably be needed. [27] They also say future trials must keep testing long after the doses end. [27]

How it works

Evolutionary biologists call this selective pressure: the antibody stops sensitive strains, so resistant ones are what get through. [27]

Seen it before

the weeds that survive

Spray a field and only the weeds the spray cannot kill come back.

Nobody knows yet

Whether several antibodies together would stop resistant HIV.

The authors say several are probably needed, and this analysis looked at VRC01 alone. [27]

Scientists map how TB's vital genes work together

Swipe up for the story ↑Scroll down for the story ↓

a map of essential genes

Scientists have mapped how the essential genes of tuberculosis bacteria work together, in a paper in Nature on Wednesday. [28]

Who is involved

the deadliest germ

Tuberculosis is the world's deadliest germ. [28] Many of its genes are still poorly understood, which holds back new drugs. [28]

Using CRISPR, a gene tool, the team turned down 2 genes at a time in the same bacterium. [28]

They tried it first in a related lab bacterium, covering 787 genes and about 2.3 million pairs of CRISPR guides. [28]

thousands of new links

The maps found thousands of links nobody had recognised. [28] Some point to pairs of drug targets worth hitting at once. [28]

Why it matters

guiding drug combinations

The authors say the maps can guide the design of drug combinations. [28]

How it works

Geneticists call this a genetic interaction: turning down 2 genes does more or less harm than the two added up. [28]

How it works

That gap shows which genes depend on each other, and so which drug pairs might work best together. [28]

Seen it before

two lamps, one room

Take away one of two lamps and the room stays lit, but take both and it goes dark.

The truth

no new drug yet

This is lab work on bacteria, and no new medicine has come from it yet. [28]

A map of the commonest adult brain cancer

Swipe up for the story ↑Scroll down for the story ↓

Scientists mapped more than 1 million cells across glioblastoma tumours, in work reported in Nature. [29]

Who is involved

Glioblastoma is the most common brain cancer in adults, with average survival of 12 to 18 months. [29]

They found that the cancer cells organise themselves in a consistent pattern from patient to patient. [29]

Who is involved

The work came from Britain's Wellcome Sanger Institute and partners including Germany's cancer research centre. [29] The atlas, GBM-Space, is free for anyone to use. [29]

Why it matters

Surgery is hard because these tumours spread through the brain. [29] Treatment can miss some cells, and the cancer returns. [29]

Why it matters

aim at the early cells

Future drugs could aim at the early cells before they turn into resistant ones. [29]

How it works

Cancer biologists call this plasticity: tumour cells change state, and the atlas shows they do it in a predictable order. [29]

Seen it before

the same stops, in order

A bus is easy to catch, however busy the city, because its stops come in the same order.

The truth

a map, not a medicine

This is a map, not a treatment. [29] The future drugs it points to do not exist yet. [29]

Swapping salt could save lives, a model says

Swipe up for the story ↑Scroll down for the story ↓

A study by The George Institute for Global Health estimates that potassium-enriched salt could prevent 2.96 million deaths a year. [33]

The team looked at 193 countries, assuming everyone switched from ordinary salt. [33]

Who is involved

This salt replaces some sodium chloride with potassium chloride, and it looks, tastes and cooks like table salt. [33]

Swapping only the salt used at home could prevent 1.85 million deaths. [33] China alone would account for 1.08 million if everyone switched. [33]

How it got here

endorsed by WHO in 2025

The World Health Organization endorsed this salt in 2025. [33]

Why it matters

70 of 100

of salt from processed and restaurant food

In Europe and North America, more than 70% of salt comes from processed and restaurant food. [33] Bruce Neal of the institute says food firms must get on board. [33]

How it works

Physiologists, who study how the body works, link high blood pressure to too much sodium and too little potassium. [33] This salt changes both. [33]

Seen it before

one swap, two gains

Swap a heavy coat for a light one with more pockets, and one change brings two gains.

The truth

“aspirational”
Vivek Jha, The George Institute

This is a computer estimate, not a trial. [33] Vivek Jha of the institute calls a global switch "aspirational". [33]

The truth

a risk with kidney disease

People with advanced kidney disease may build up too much potassium. [33] Jha says labels and clinical oversight can manage that. [33]

Portugal tries sterile mosquitoes as dengue rises

Swipe up for the story ↑Scroll down for the story ↓

Portugal released 30,000 sterile male tiger mosquitoes in September, its second attempt to shrink their numbers. [34]

By the end of October, Italy had 76 dengue cases caught locally and France 8. [34] That is roughly twice as many as in 2025. [34]

How it got here

Tiger mosquitoes came to Italy in the 1990s in shipments of used tyres, and they spread dengue, chikungunya and Zika. [34]

The mosquito moves about 60 kilometres north each year, partly in cars. [34] Disease outbreaks move faster, about 120 kilometres a year, says epidemiologist Jan Semenza. [34]

Why it matters

Travellers bring the virus back, a local mosquito bites them, and it then infects someone else. [34]

Why it matters

testing wastewater at airports

EU health officials now test wastewater at big airports to spot dengue before patients reach a doctor. [34]

How it works

Insect scientists call this the sterile insect technique: sterilised males mate, but no offspring follow, as Portugal hopes. [34]

Seen it before

dud seeds, fewer plants

If half the seeds in a packet are duds, fewer plants come up.

The truth

no result yet from Portugal

Semenza says eliminating the mosquito is not realistic once it has settled. [34] The report gives no result yet from Portugal's releases. [34]

A nasal MS drug hits one goal, at its lower dose

Swipe up for the story ↑Scroll down for the story ↓

Tiziana Life Sciences, a London and Boston biotech, tested a nasal drug, foralumab, in 48 people with multiple sclerosis (MS). [24]

Who is involved

a slowly worsening form of MS

MS is a disease of the brain and nerves. [24] These patients have a form that slowly worsens without flare-ups. [24]

The lower dose met the goal and the higher did not, in a trial of 48.

Brain scans showed less inflammation at the 50 microgram dose than on a dummy. [24] The 100 microgram dose missed that goal. [24]

All 48 finished the 12 weeks, and no serious side effects were linked to the drug. [24]

Tiredness scores improved by 6.17 and 7.18 points on the two doses. [24] A measure of disability showed no benefit. [24]

Why it matters

no drug made for them

No US-approved drug is aimed at this form, so these patients have no treatment made for them. [24]

How it works

Doctors call a scan like this a surrogate endpoint: it stands in for how patients fare. [24] Here, disability did not improve. [24]

Seen it before

a tidy desk, the same homework

A tidier desk does not prove the homework got better.

The truth

These figures come from the company's own release of results. [24]

Tiziana plans to discuss the results with the FDA, the US drug regulator. [24]

A gene keeps bone's stem cells in reserve, in mice

Swipe up for the story ↑Scroll down for the story ↓

HOXA10, in mice

Researchers at NYU Langone Health found that a gene, HOXA10, keeps a lifelong supply of bone stem cells in mice. [30]

90 of 100

of the stem cells and their descendants gone

They deleted the gene in 6-day-old mouse pups, in a study in Science Advances. [30] 15 months later, 90% of the stem cells and their descendants had gone. [30]

Mice without the gene could not heal breaks properly. [30] Stem and early bone cells made up 48% of the healing tissue, against 76% in normal mice. [30]

In bone samples from people, silencing 3 related genes cut stem cells further, and cell death rose by 50%. [30]

Why it matters

“burns through its reserves too early”
Philipp Leucht, NYU Langone

Without the gene, bone "burns through its reserves too early", as in ageing bone, says surgeon Philipp Leucht. [30]

How it works

Stem-cell biologists call this self-renewal: a stem cell copying itself to keep a reserve. [30] HOXA10 brakes it from maturing too soon. [30]

Seen it before

savings kept for an emergency

Money kept in a savings account is still there when the car breaks down.

The truth

This is mostly mouse work. [30] The authors see a possible drug target, and no treatment exists from it. [30]

Alethio raises $90 million for rare blood cancers

Swipe up for the story ↑Scroll down for the story ↓

Alethio Therapeutics, a UK startup spun out of the University of Oxford, raised $90 million, it announced on Thursday. [32]

Who is involved

It targets myeloproliferative neoplasms, rare slow blood cancers in which the body makes too many blood cells. [32] They can cause clots and scarred bone marrow. [32]

Its lead drug, ATX-011, is an antibody, and it should enter human testing in the first half of 2028. [32]

today's treatments

Blood withdrawals and existing drugs such as Jakafi manage these conditions. [32] The chief says they do not help most patients enough. [32]

Why it matters

About 150,000 people in the US have essential thrombocythemia, one of these cancers, Alethio says. [32] An investor says that gives its drug greater reach. [32]

How it works

Pharmacologists call this targeting: ATX-011 binds G6b, a protein only on cells driving these diseases, Alethio says. [32]

Seen it before

one key, one lock

A key cut for one lock opens that door and leaves the rest shut.

The truth

Its chief calls ATX-011 "a well-behaved medicine", but no person has yet taken it. [32]

EU cancer groups fear a budget squeeze

Swipe up for the story ↑Scroll down for the story ↓

Cancer groups fear losing money in the European Union's next long-term budget, for 2028 to 2034. [35]

Who is involved

The European Commission, the EU's executive, proposes a shared fund for health, biotechnology, farming and the bioeconomy. [35]

How it got here

two cancer plans, running until 2030

The Beating Cancer Plan and the Cancer Mission both run until 2030, into the first years of that budget. [35]

“Projects that are making a real difference”
Isabel Rubio

"Projects that are making a real difference" now face an uncertain future, says Isabel Rubio of the European Cancer Organisation. [35]

“generally be eligible”
Commission spokesperson

A Commission spokesperson says current health work would "generally be eligible" to compete for money. [35] Germany's health ministry agrees. [35]

Why it matters

Those projects train doctors and give young people with cancer a voice, Rubio says. [35]

How it works

Budget experts call a dedicated pot ring-fencing: money that cannot go elsewhere, which cancer groups fear losing here. [35]

Seen it before

money in its own jar

Pocket money kept in its own jar cannot get spent on snacks by mistake.

The truth

no figure given

This report gives no figure from either side for what cancer work would get under the new fund. [35]

What comes next

A deal between EU countries is expected by the end of the year. [35]

Nobody knows yet

How much money cancer projects will get in the EU's next budget.

The Commission says current work would generally be eligible to compete, and gives no figure. [35]

A cleaner way to edit genes in marmosets

Swipe up for the story ↑Scroll down for the story ↓

Researchers injected gene-editing tools into marmoset eggs just before fertilisation, in a paper in Scientific Reports. [31]

Who is involved

marmosets, small monkeys

Marmosets are small monkeys with short pregnancies and early maturity, so labs use them to make animals with altered genes. [31]

Editing an embryo often leaves a mosaic, in which some cells are changed and others are not. [31]

The team found that a marmoset embryo starts copying its DNA about 8 hours after fertilisation. [31] So they edited before that. [31]

3 of 3

genes changed

They made marmosets with changes in 3 genes, and all were likely free of mosaics. [31]

Why it matters

years saved

Marmosets take years to breed a second generation, so getting the first animal right saves years of waiting. [31]

How it works

Geneticists call this avoiding mosaicism: an edit made before the DNA is copied reaches every later cell. [31]

Seen it before

change the recipe early

Change a recipe before the cakes bake and every cake changes, but halfway through only some do.

The truth

“likely”
the paper's authors

The authors say the animals were "likely" free of mosaics. [31] This is an animal-lab method, and it treats nobody. [31]
