A new study has found that a combination of two drugs could enhance the immune system to treat one of the most common types of cancer in the world, bowel cancer. Also known as colorectal cancer, despite its widespread presence, the treatment options for this condition are limited. What the study specifically found was that this procedure could shrink the tumours caused by this condition by around 60%.

What Are The Drugs Involved

The trial involved the use of two immunotherapy drugs, botancilimab and balstilumab. It is a monoclonal antibody that works to stimulate the body's immune system to attack cancer. The study is a rather significant find, as it’s the first time that a consistent and durable response to immunotherapy has been reported in patients with solid MSS mCRC tumours.

The study was divided into several phases for more than 6 months. In the US trial, around around 101 patients with microsatile stable metastatic colorectal (MSS-mCRC) tumours showed a decrease . Around 61% of the patients experienced tumour shrinkage or stabilization after combined treatment with votancilumab and balstilumab. When it comes to downsides, diarrhea and fatigue were found to be the most common side effects or side effects of this drug.

These results are interesting and open to exploration. To date, immunotherapy has not been effective in patients with CNS-mCRC tumors. This study demonstrates the potential of the combination of botenlimab and balstilimab in the treatment of CNS mCRC, providing new hope for people diagnosed with colon cancer.

What Could This Mean For Bowel Cancer Treatment In The Future

The study is currently in the final stages of clinical trials, and the US Food and Drug Administration (FDA) hopes to quickly gain approval for its use because of the importance of this area that affects many people. The efficiency shown demonstrates the potential of botansilimab to contribute to broad antitumor immunity.

All in all, the combination of botensilimab and balstilimab represents a promising new direction in the treatment of colorectal cancer. This breakthrough could improve conditions for many patients worldwide and lights a new hope in the fight against this common disease. The results of this study show the effectiveness of immunotherapy in this field and how its potential to transform cancer treatment can only grow in the years to come.

Even as dengue continues to wreak havoc globally, with more than 7.37 million cases reported worldwide so far in 2026, an experimental monoclonal antibody (mAb) has shown promise as a potential treatment in a Phase 2 trial.

Led by Pune-based Serum Institute of India, the trial found that Dengue-mAb cleared dengue viremia and fever within 24 hours, offering early evidence of a potential therapeutic effect against the virus.

“This first-in-patient phase 2 randomized clinical trial demonstrated the safety of Dengue-mAb and its action on the clearance of dengue virus and fever,” the researchers, including those from Serum, said. “This is, to our knowledge, the first evidence of a preliminary therapeutic effect in patients with dengue.”

What Did The Trial Find?

Detailed in JAMA Network Open, the researchers found that the experimental Dengue-mAb was safe and well-tolerated and showed evidence of a therapeutic effect.

Dengue-mAb is a human-engineered, recombinant monoclonal antibody that neutralized all four dengue virus serotypes in animal studies and demonstrated safety in a Phase 1 trial in healthy adults.

The findings were based on a randomized, placebo-controlled trial involving 250 adults with dengue and a history of fever onset within 48 hours. Participants received one of four doses of Dengue-mAb — 3, 5, 7, or 9 milligrams per kilogram (mg/kg) — or a placebo, with 50 participants assigned to each group.

The primary outcomes were reduction in viremia at 24 hours and causally related serious adverse events (SAEs).

The antibody showed rapid activity against dengue virus and fever at all four dose levels tested.

Among participants who had detectable viremia at baseline, those treated with the 5- to 9-mg/kg doses became negative for dengue virus by eight hours, compared with 72 hours with placebo.

At 24 hours, fever clearance ranged from 92.9% to 100% in the Dengue-mAb groups, compared with 58.3% in the placebo group.

Dengue affects more than 200 million people each year, mainly in tropical and subtropical regions, and is expanding into new areas amid climate change and rapid urbanisation. The incidence of severe disease is also rising, increasing the need for effective treatments.

The result matters because there is currently no licensed antiviral drug for dengue anywhere in the world. Three vaccines are licensed, but people who develop dengue today generally receive supportive care, including fluids, fever control and monitoring, rather than a treatment that acts directly on the virus.

Dengue-mAb targets the virus, not just the symptoms. The rapid reduction in viremia raises the possibility of a treatment that could change how dengue is managed. However, whether the antibody can prevent severe dengue, hospitalization or deaths is not yet known.

Much of the dengue burden falls on health systems that may struggle to deliver an infused biologic to outpatients within 48 hours of fever onset.

What Happens Next?

The finding is still early. Phase 2 trials assess whether a drug produces a measurable effect in a relatively modest number of patients. They are not the studies regulators use to approve a medicine, and this candidate remains years away from becoming widely available.

Dengue Cases Worldwide And In India

According to WHO global surveillance data, more than 7.37 million dengue cases have been reported worldwide, including about 2.83 million confirmed cases and more than 5,100 deaths. India has reported more than 33,000 cases and over 40 deaths.

Amid concerns over the MMR vaccine and falling childhood vaccination rates in the US, another child has died with measles.

The death was confirmed by Lancaster County Coroner Stephen Diamantoni, who said his office was investigating the case. He said the child died “a few weeks ago” but could not confirm whether it was the death Pennsylvania Gov. Josh Shapiro referred to last week.

“We just want to cast as wide a net as possible and identify any deaths that may have occurred in individuals who had measles,” Diamantoni said.

It remains unclear whether this is the second or third measles-associated death reported in the US this year.

Pennsylvania Reports Two Measles-Associated Deaths

In late August, Pennsylvania reported two measles-associated deaths in 2026, both involving unvaccinated individuals. One was reportedly an infant, while details about the second person have not been released.

The deaths are the first measles-related deaths reported in Pennsylvania in 35 years, according to the state Department of Health.

The infant’s death has been disputed. Lancaster County Coroner said the newborn tested positive for measles but died shortly after birth from a lacerated spleen. Measles antibodies were found during postmortem testing.

“The newborn had measles” but did not “die of measles,” Parsons said, citing the coroner.

CDC Challenges The Deaths

The CDC has not included the two Pennsylvania deaths in its national measles count while it reviews additional information about the circumstances and causes of death.

According to the CDC, available information does not establish whether measles caused or contributed to the deaths or whether the individuals died from other causes while infected with measles.

The Department of Health and Human Services said the deaths had not been confirmed based on the information available to the CDC.

Pennsylvania, however, maintains that it followed the standard process and provided the CDC with the required epidemiological data.

The state calls the deaths “measles-associated,” meaning there is laboratory or epidemiological evidence of measles, even if the virus is not established as the immediate cause of death.

The US CDC has 2,903 confirmed measles cases in the US in 2026, as of August 27, 2026, the highest number in 35 years.

The cases are spiraling amid anti-vaccine stance promoted by the Trump-led US government and HHS Secretary RFK Jr.

More recently, Trump also announced a split of the MMR vaccine.

Measles has been considered eliminated in the US since 2000, but the Pan American Health Organization is expected to decide in November whether the US has lost its elimination status.

What Is Measles?

Measles is one of the most contagious infectious diseases. An infected person can spread the virus to around nine out of 10 unvaccinated people exposed to it.

Most people recover, but measles can cause serious complications, including pneumonia, brain inflammation and death.

Infants, pregnant women and people with weakened immune systems are particularly vulnerable.

Why Measles Is More Than A Fever And Rash

Early measles symptoms can resemble a common cold and include:

• High fever, which can exceed 104°

• Persistent

• Runny

• Red, watery eyes

A distinctive sign of measles is the appearance of tiny white spots, called Koplik spots, inside the mouth. These spots typically develop two to three days after the initial symptoms begin. Their presence is an important diagnostic clue and often appears before the characteristic measles rash.

What Does A Measles Rash Look Like?

A rash appears three to five days after the initial symptoms. It usually starts as flat, red spots on the face, near the hairline, and then spreads downward to the neck, trunk, arms, legs and feet.

The spots can sometimes be slightly raised and may merge. When the rash appears, the fever may also increase significantly.

Who Is Most At Risk?

Groups at higher risk of measles complications include:

• Children younger than

• Adults older than

• Pregnant

• People with weakened immune systems, including those with leukemia or HIV

How To Prevent

Two doses of the MMR vaccine are key to preventing measles. Te first MMR dose is recommended at 12 to 15 months, followed by a second dose at 4 to 6 years.

UK health officials have reported the breeding of an invasive mosquito species known to spread dengue, chikungunya and Zika viruses.

While this is the fourth time Aedes aegypti has been detected in the UK, it is the first time the species has been found breeding. The mosquitoes were found reproducing in homes in east London.

The UK Health Security Agency (UKHSA) said the risk to the public is low, with no evidence of human infections linked to these mosquitoes.

Officials believe the mosquitoes may have been accidentally imported in baggage, vehicles or plants. Measures to destroy larvae, along with surveillance and trapping, have been stepped up.

What Does This Mean For Public Health?

Mosquito-borne diseases kill more than one million people and infect up to 700 million each year.

While Aedes aegypti mosquitoes are usually found in tropical and subtropical climates, the current risk to the UK public remains low. The species is unlikely to survive long-term in the UK's colder temperatures.

UKHSA head of medical entomology Dr Jolyon Medlock said: "There is no evidence that these mosquitoes have caused human infections and importantly, to date, there is no evidence of the mosquitoes or larvae being detected in nearby public areas."

Dr César López-Camacho of the University of Oxford called the finding "important" but said it was not a reason for alarm.

Is Climate Change To Blame?

Despite recent heatwaves, the overall UK climate remains too cold for Aedes aegypti to survive long-term, UKHSA said.

The mosquitoes were detected through the Mosquito Watch scheme, which monitors invasive species.

Medlock said the UK will continue to see invasive mosquitoes and that, as the climate warms, he expects more reports of them surviving.

Globally, dengue cases are increasing across the Western Pacific and Southeast Asia. These increases are fueled by climate change, globalisation and immunological naïveté, alongside the limited impact of existing control measures.

“While the current mosquitoes are unlikely to be infected, and so the risk to people will be low, their presence may indicate a regular summer event in future years. These mosquitoes will not survive the cooler weather of autumn or winter, but new introductions next year may lead to breeding again,” Martin Hibberd, Professor of Emerging Infectious Disease at the London School of Hygiene & Tropical Medicine (LSHTM), said.

He said the mosquitoes live in and around human habitations and are well adapted to city life, requiring the right climate conditions, which the UK is now experiencing more regularly.

Dr Robert Jones, Assistant Professor in the Department of Disease Control at LSHTM, said: “Even in outbreak situations, only a fraction of mosquitoes are infected, so the risk to the public from this finding is very low.”

He advised people to make gardens and outdoor spaces less suitable for mosquitoes by removing standing water.

“Mosquitoes can lay eggs in buckets, containers, plant pots and other places where water accumulates, so removing standing water can help limit the places available for them to lay eggs and reduce the likelihood of populations becoming established.”

How To Prevent Mosquito Bites?

To lower your risk of dengue and other mosquito-borne diseases:

• Wear clothes that cover as much of the body as possible
• Use mosquito nets, ideally treated with insect repellent, when sleeping during the day
• Install window screens
• Use repellents containing DEET, picaridin or IR3535
• Use coils and vaporizers

How To Stop Mosquitoes From Breeding?

• Remove places where water can accumulate
• Dispose of solid waste properly
• Cover, empty and clean domestic water-storage containers weekly
• Remove artificial containers that can hold water
• Use appropriate insecticides in outdoor water-storage containers

Mosquito detection and eradication programs are key to preventing the problem from becoming a bigger public-health risk.
