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.

Pancreatic cancer has long been one of the toughest challenges in oncology. With a five-year survival rate hovering around 13 per cent and recurrence rates approaching 80 per cent after treatment, the odds have historically been stacked against patients.

However, an experimental drug called daraxonrasib, developed by the US-based late-stage clinical oncology company Revolution Medicines, has shown promise in improving survival rates in patients with metastatic pancreatic ductal adenocarcinoma (PDAC).

“For patients with metastatic pancreatic cancer, new treatment options are urgently needed to increase survival time and improve quality of life,” said Brian M. Wolpin, professor of medicine at Harvard Medical School, and principal investigator for the trial.

Wolpin noted that the study “indicates that daraxonrasib provides a clear and highly meaningful step forward for patients with pancreatic cancer who have experienced progression on prior treatment, typically chemotherapy.”

What Is Daraxonrasib?

Daraxonrasib is a once-daily oral pill that demonstrated statistically significant and clinically meaningful improvements in progression-free survival (PFS) and overall survival (OS) compared with standard intravenous chemotherapy.

Daraxonrasib, described as a multi-selective inhibitor of RAS(ON) proteins, is the first investigational drug in a new class of RAS inhibitors designed to target a broad spectrum of cancer-causing RAS mutations.

In the clinical trial, daraxonrasib showed a median overall survival of 13.2 months, compared with 6.7 months for chemotherapy.

The drug was generally well tolerated and showed a manageable safety profile, with no new safety concerns identified.

Daraxonrasib works by blocking KRAS signalling proteins that drive tumor growth.

Pancreatic cancer is considered one of the most RAS-addicted cancers, with more than 90 per cent of patients carrying tumours driven by RAS protein mutations.

Daraxonrasib: The Clinical Trial

The controlled Phase 3 clinical trial evaluated daraxonrasib in patients with previously treated metastatic PDAC.

The trial included patients with pancreatic tumours carrying a wide range of RAS variants, as well as patients without identified RAS mutations.

The results showed that daraxonrasib significantly improved overall survival in patients with previously treated metastatic pancreatic cancer.

Similar RAS-targeting drugs are now being developed by other companies for pancreatic, lung, and colon cancers.

“It’s the beginning, not the end,” said Elizabeth Jaffee in comments to The New York Times.

What are the side effects?

According to the company, “Daraxonrasib was generally well tolerated, with a manageable safety profile and with no new safety signals.”

Prior studies with daraxonrasib have shown that rash is the most common side effect, with mouth sores, diarrhea, nausea, and vomiting also common.

FDA fast-tracks Daraxonrasib

Based on the first interim analysis, all progression-free survival and overall survival results are now considered final.

Revolution Medicines said it plans to submit the data to global regulators, including the US Food and Drug Administration (FDA), as part of a future New Drug Application under a Commissioner’s National Priority Voucher.

The findings are also expected to be presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting.

What Is Pancreatic Cancer? Know The Warning Signs

Pancreatic cancer typically begins in the ducts of the organ and can rapidly spread from there to the rest of the organ. Early-stage pancreatic tumors do not show up on imaging tests, making this version of the disease difficult to diagnose until it infects other organs.

The prevention and early detection remain vital.

Experts warn that pancreatic cancer often masquerades as common ailments, delaying diagnosis. Here are some early symptoms that should never be ignored:

• Abdominal or back pain that worsens over time or eases when leaning forward.
• Unexplained weight loss without changes in diet or exercise.
• Jaundice, including yellowing of the eyes and skin, sometimes with intense itching.
• Changes to urine or stool, such as dark urine or pale, greasy stools.
• New-onset diabetes without obvious risk factors.
• Persistent fatigue unrelated to poor sleep or lifestyle

A French woman infected with the deadly hantavirus outbreak linked to the MV Hondius cruise ship is critically ill and is being treated using an artificial lung.

The woman is among the passengers evacuated from Spain’s Canary Islands. According to the World Health Organization (WHO), 11 people have been affected by the rat-borne virus so far, of whom three have died.

A Dutch couple is believed to have been first exposed to the virus while visiting a birdwatching site in Argentina.

The WHO has confirmed that the Andes strain of hantavirus — the only strain known to spread from person to person — is behind the outbreak.

Patient Suffers Severe Lung And Heart Complications

The French passenger, currently hospitalized in Paris, has developed a severe form of the disease that has caused life-threatening lung and heart complications, Dr. Xavier Lescure, an infectious disease specialist at Bichat Hospital, told AP News Agency.

He explained that “the woman is on a life-support device that pumps blood through an artificial lung, providing it with oxygen and returning it to the body. The hope is that the device relieves enough pressure on the lungs and heart to give them some time to recover.”

Lescure described it as “the final stage of supportive care.”

With the evacuation of all passengers and many crew members completed, the MV Hondius is now sailing back to the Netherlands, where it will undergo cleaning and disinfection.

Hantavirus: No Pandemic Potential

Speaking to HealthandMe, Dr. Amitav Banerjee, professor at DY Patil Vidyapeeth, Pune, and former field epidemiologist in the Indian Armed Forces, said hantavirus does not spread easily from person to person.

Unlike COVID-19, it does not have significant aerosol or pandemic potential. Only certain strains, such as the Andes strain identified in South America, have shown limited person-to-person transmission, usually through very close or intimate contact involving body fluids.

“That is why the husband and wife may both have become infected. Even then, transmission is rare and requires prolonged close exposure. Basic precautions are generally sufficient, and asymptomatic individuals are unlikely to transmit the infection,” he said.

Dr. Amitav added that hantavirus does not have pandemic potential under natural conditions because it spreads poorly between humans and remains largely linked to rodent exposure.

Hantavirus: How to Prevent The Risk

Dr. Jatin Ahuja, Consultant in Infectious Diseases at Indraprastha Apollo Hospital, Delhi, told HealthandMe that the general public has no reason for alarm.

“Hantavirus infections remain rare globally, and awareness about rodent control and early symptom recognition continues to be the most effective approach,” he said.

He recommended simple preventive measures to significantly reduce risk.

“People should avoid sweeping or vacuuming rodent-infested areas directly, as this may spread contaminated particles into the air. Instead, affected areas should be ventilated first and cleaned using disinfectants while wearing gloves and masks. Proper storage of food, sealing entry points for rodents, and maintaining hygiene in homes, warehouses, and workplaces are also important preventive steps,” the expert added.

Eli Lilly has launched Lormalzi, the Indian version of the US FDA-approved donanemab, for the early treatment of Alzheimer’s disease in the country. The drug can also be used for people with mild cognitive impairment and mild dementia.

Dementia affects around 8.8 million people in India, and Alzheimer’s accounts for the majority of cases. The number is expected to nearly double by 2036.

The once-monthly therapy, administered as an intravenous infusion, targets amyloid plaques in the brain and may help slow disease progression in selected patients with mild cognitive impairment or early dementia.

“For 35 years, Lilly has been a global pioneer advancing research of therapies and diagnostics for people with Alzheimer’s disease,” said Winselow Tucker, President and General Manager of Eli Lilly India. He added that Alzheimer’s imposes a major emotional and economic burden on patients, caregivers, and healthcare systems.

What Is Lormalzi?

Lormalzi is a monoclonal antibody therapy designed to target amyloid-beta plaques in the brain — one of the hallmark features associated with Alzheimer’s disease.

The drug works by helping the immune system remove these abnormal protein deposits, which are believed to contribute to memory loss and cognitive decline.

The FDA approved the therapy in 2024 under the brand name Kisunla. Globally, Kisunla is sold in countries including the US, Japan, and parts of Europe.

Lormalzi: Who Can Get The Treatment?

Donanemab is best suited for people with:

• Early symptomatic Alzheimer’s disease
• Mild cognitive impairment (MCI) due to Alzheimer’s
• Mild Alzheimer’s dementia
• Amyloid-positive patients (confirmed by amyloid PET/CSF or blood biomarkers)

It is not meant for those who have already progressed to advanced stages.

Moreover, while the drug can dissolve the build-up of amyloid-beta protein in the brain, it cannot reverse the damage that has already occurred.

Lormalzi: How Much Does It Cost In India?

Eli Lilly has priced Lormalzi at Rs 91,688 for a 350 mg vial in India. Reports suggest the treatment duration may extend up to 18 months, potentially making it expensive for many patients.

Lormalzi’s Safety And Efficacy: Are There Any Side Effects?

Clinical trial data from Eli Lilly’s Phase 3 TRAILBLAZER-ALZ 2 study showed that donanemab slowed cognitive and functional decline.

The study, involving 1,736 patients — 860 of whom received the infusion every four weeks until amyloid clumps cleared — found that donanemab slowed cognitive decline in early Alzheimer’s patients by 35.1 per cent over 76 weeks.

However, the drug is known to cause amyloid-related imaging abnormalities (ARIA), including swelling or bleeding in the brain, most of which are asymptomatic. The study showed that 24 per cent of participants experienced ARIA involving brain swelling, while 19.7 per cent experienced brain bleeds. Three treatment-related deaths were also reported.

Symptoms may include headache, confusion, visual disturbances, and, in rare cases, seizures. Hence, MRI monitoring is essential during treatment.

Notably, the risk may be higher in people with APOE ε4 carriers and patients on blood thinners, Dr. Sudhir Kumar, neurologist at Apollo Hospitals, Hyderabad, shared in a post on social media platform X.

Leqembi (lecanemab) is not yet formally registered or widely marketed for general sale in India. While it is on track for introduction in the country, the Alzheimer’s therapy can reportedly be accessed through specialised import channels (Named Patient Supply) with a valid prescription.

Lecanemab is a disease-modifying therapy for early Alzheimer’s disease, administered via intravenous infusion every two weeks to slow cognitive decline.

In contrast, donanemab is administered once every four weeks.

Additionally, treatment with donanemab can be halted after a certain level of amyloid protein clearance is achieved, with patients in the study switching to placebo thereafter.

“In the absence of amyloid PET imaging, which is currently not available in India, the evidence-based approach is to treat patients with donanemab for 18 months,” the company said.

How Does The Treatment Work?

“Donanemab is a newer anti-amyloid antibody designed to slow progression of Alzheimer’s disease by clearing amyloid plaques from the brain,” Dr. Sudhir said.

He noted that “donanemab represents an important scientific advance because it targets underlying Alzheimer pathology rather than only symptoms”.

According to an Eli Lilly spokesperson, treatment in India is expected to continue for 18 months (76 weeks) in most patients because amyloid PET imaging, often used internationally to assess plaque clearance, is not yet widely available in India.

Treatment may be stopped earlier if:

• Serious safety concerns develop
• Patients experience adverse effects
• The disease progresses to moderate Alzheimer’s disease

Lormalzi: Is It A Cure For Alzheimer’s?

Dr. Sudhir stated that “not all dementia patients benefit”. He added that Lormalzi “is not a cure; it does not reverse established dementia”.

“The benefit is modest, but clinically meaningful in selected patients.” He also stressed the need for carefully selecting patients for the therapy.

“Lifestyle measures, cognitive engagement, vascular risk control, sleep, hearing correction, and caregiver support remain extremely important,” Dr. Sudhir said, adding that “Alzheimer’s care is still much more than a single drug”.
