Japan could become one of the first countries in the world to end the HIV epidemic, says the president of Gilead Sciences Japan, Kennet Brysting. The idea for now could seem a little too ambitious, but it is not entirely unrealistic, given that the availability of medicines that can prevent transmission of HIV. Drugs are not the cure, but control over the spread of virus to the point where the disease is no longer a major public health threat.

What Is The Role Of Preventative HIV Medicines?

Gilead's have two key drugs, Truvada and lenacapavir. These two are playing a crucial role in prevention. Truvada is taken as a daily pill, while lenacapavir requires two injections per year. It can make the virus undetectable in infected individuals and prevent transmission to those who are not infected yet. In trials, lenacapavir showed 100% efficacy in preventing HIV infections. This is why it is describe as "almost a vaccine".

In 2024, Japan also approved Truvada for HIV prevention, but the country has yet to approve lenacapavir for the same. Until now, people in Japan had been importing generic versions of Truvada or purchasing it from clinics that source it from overseas.

HIV In Japan

Up until now, Japan reported around 25,000 HIV infections, whereas 669 new cases were reported in 2023. For seven consecutive years, the number of new infections remained under 1,000. The downward trend thus shows that the virus has been controlled, however, getting to zero new infections remains the ultimate goal.

Brysting too acknowledged that simply having effective drug is not enough. What is important is to have a proper implementation, access and healthcare support to make sure that these treatments are widely available and effective.

What Are The Challenges In Implementation?

The biggest challenges is testing rates. There is a need to increase testing rates. At this very moment, around 86% people infective with Japan have been tested, but the goal is to increase it up to 95%, with an ideal goal of 100%. Without widespread testing, many infected people may not even know that they are infected and it could transmit the virus.

Another measure issue is the cost of preventative medication. While Japan's health insurance covers treatments for diseases, it does not cover preventative drugs. Those who purchase Truvada for prevention, pay around $470 per month. Some clinics in Tokyo offer generic alternatives too, which is cheaper, but they are not ideal.

Better Healthcare Support

Brysting expressed concern that individuals importing medications might not be consulting doctors regularly, which is essential for monitoring HIV status and overall health. Truvada users need to be tested for HIV initially and every three months, along with screenings for other infections and kidney function checks. Without proper medical supervision, there is a risk of misuse and inadequate protection.

Gilead is in discussions with Japanese authorities to improve access and insurance coverage for Truvada, and progress is being made. Japan has shown efficiency in approving critical medicines, as seen during the COVID-19 pandemic when Gilead’s remdesivir was approved in just three days.

What Is The Way Ahead?

Gilead at this moment is not only focused on HIV and hepatitis C, but also expanding into oncology with innovative treatments like CAR-T cell therapy, which strengthens a patient's immune system to fight cancer.

However, Japan’s strict approval processes can slow down drug availability. Phase 3 clinical trials often need to be conducted within the country, and Japan tends to approve medicines much later than other regions. For instance, Truvada was approved for prevention in Japan 12 years after the U.S. and nearly 20 years after its approval for treatment. inancial factors also play a role. The Japanese government adjusts drug prices annually, often reducing them, which can make long-term investment challenging for pharmaceutical companies.

Unlike many other cancers, cervical cancer is considered highly preventable through a combination of HPV vaccination, regular screening, and timely treatment of precancerous lesions.

India has recorded a significant decline in cervical cancer burden, with new cases falling by 37% over the past decade, according to data from the Indian Council of Medical Research's (ICMR) National Cancer Registry Programme (NCRP).

Experts say widespread screening, awareness, and increasing uptake of the human papillomavirus (HPV) vaccine have contributed to the milestone.

Cervical Cancer Cases Drop In India

The latest estimates show that the number of new cervical cancer cases has dropped from approximately 1.27 lakh annually to around 79,000, marking a major public health milestone in the fight against one of the most common cancers affecting Indian women.

"Cervical cancer is one of the few cancers that can largely be prevented through timely screening and vaccination," Dr. Amitabh Shankar, Head of Preventive Oncology at Dr. B.R. Ambedkar Institute Rotary Cancer Hospital, AIIMS, was quoted as saying.

He attributed the decline to improved awareness, wider availability of screening services, and the gradual expansion of HPV vaccination.

Positive Impact Of Screening And HPV Vaccination

According to experts, early detection through routine cervical cancer screening allows precancerous changes to be identified and treated before they develop into cancer.

At the same time, HPV vaccination protects against high-risk strains of the human papillomavirus, the leading cause of cervical cancer.

The report suggests that increased access to healthcare services, government-led awareness initiatives, and preventive programs have played an important role in reducing the cases of cervical cancer.

Despite the progress, specialists caution that cervical cancer continues to be a major health concern in India, particularly in rural and underserved regions where screening coverage and HPV vaccination remain limited.

They emphasize that expanding HPV vaccination among eligible adolescents, strengthening population-based screening programs, and improving early diagnosis will be essential to prevent it.

About HPV Vaccine

The human papillomavirus causes more than 200 known infections. While some types lead to benign skin warts, others are responsible for severe health threats, such as cervical, throat, anal, and penile cancers.

The HPV vaccine provides strong protection against the most lethal strains, avoiding long-term health complications. It helps the immune system recognize and fight off high-risk strains of the virus before they cause harm. It protects against:

• Genital warts
• Cervical cancer
• Vaginal, vulvar, anal, and penile cancers
• Mouth, throat, head, and neck cancers linked to HPV

What Is Cervical Cancer?

Cervix is located in the pelvic cavity, about 3 to 6 inches inside the vaginal canal. It serves as the entrance to the uterus to the vagina. As per the World Health Organization (WHO), almost all cervial cancer are linked to human papillomaviruses (HPV) which are transmitted through sexual contact

Symptoms Of Cervical Cancer

Cervical cancer has no symptoms in the early days and therefore, is hard to detect until it has spread. Early-stage cervical cancer symptoms include:

• Vaginal bleeding after sex
• Vaginal bleeding post-menopause
• Vaginal bleeding between periods or unusually heavy/long periods
• Watery vaginal discharge with a strong odour or containing blood
• Pelvic pain or pain during intercourse

• Persistent early-stage symptoms
• Painful or difficult bowel movements or rectal bleeding
• Painful or difficult urination or blood in the urine
• Persistent dull backache
• Swelling of the legs
• Pain in the pelvis or lower abdomen

Takeda Biopharmaceuticals India today announced that QDENGA (TAK-003) has become the first dengue vaccine to receive approval in India, marking a major milestone in the country's fight against the mosquito-borne disease.

The Drug Controller General of India (DCGI) has granted market authorization for QDENGA to prevent dengue in individuals aged 4-60 years. According to Takeda, it is India's first approved dengue vaccine and can be administered regardless of previous dengue infection, without requiring pre-vaccination testing.

"Since its launch in 2022, QDENGA has been approved in 43 countries, with more than 32 million doses distributed globally. This approval marks an important step forward in strengthening dengue prevention in India," said Dr. Mahender Nayak, Head of Intercontinental Markets.

QDENGA Vaccine: Why The Approval Matters

The approval comes at a critical time as dengue cases in India have risen sharply over the past two decades.

India accounts for nearly one-third of the global dengue burden. In 2025, more than 113,000 dengue cases were officially reported, although modelling studies suggest the true number of infections may run into tens of millions annually due to underreporting.

Rapid urbanization, climate change and widespread mosquito breeding have made dengue a year-round public health concern. Since there is no specific antiviral treatment for dengue, prevention remains the most effective strategy.

"India carries a substantial dengue burden, and all four dengue virus serotypes co-circulate in several regions. QDENGA is designed to protect against all four serotypes regardless of prior exposure," said Dr. Goh Choo Beng, Medical Affairs Head, Southeast Asia & India Cluster.

QDENGA: Scientific Evidence

The DCGI approval is supported by Takeda's global clinical development programme comprising 19 Phase 1, 2 and 3 clinical trials involving more than 28,000 participants in dengue-endemic and non-endemic regions.

The pivotal Phase III TIDES (DEN-301) study enrolled more than 20,000 participants across eight countries and evaluated the vaccine's long-term safety and effectiveness.

Key findings include:

• 80.2% vaccine efficacy against virologically confirmed dengue one year after the second dose.
• 90.4% efficacy against dengue-related hospitalization at 18 months.
• 84.1% protection against dengue-related hospitalization after 4.5 years.
• Safety and efficacy data demonstrating protection for up to seven years across all four dengue virus serotypes.

The approval is also supported by an Indian Phase III (DEN-302) trial involving participants aged 4-60 years, which found QDENGA to be safe, well-tolerated and immunogenic in children, adolescents and adults.

What Is QDENGA?

QDENGA (TAK-003) is a live-attenuated tetravalent dengue vaccine designed to protect against all four dengue virus serotypes.

It is administered as two 0.5 mL subcutaneous doses, given three months apart.

The vaccine is built on a DENV-2 backbone, incorporating structural proteins from DENV-1, DENV-3 and DENV-4 to provide broad immune protection.

The World Health Organization (WHO) recommends QDENGA for use in dengue-endemic settings without the need for pre-vaccination screening. The vaccine is also included in the WHO List of Prequalified Vaccines, allowing procurement through agencies such as UNICEF and PAHO.

The vaccine has been approved in 43 countries across Asia, Latin America and Europe. It is already part of Brazil's National Immunization Program and is available through public immunization programmes in Argentina, Colombia and Indonesia.

Who can take QDENGA?

The vaccine is approved in India for people aged 4-60 years to help prevent dengue disease.

Manufacturing In India

Takeda had partnered with Indian vaccine manufacturer Biological E in 2024 to expand production of QDENGA.

Under the agreement, Biological E plans to manufacture 50 million doses annually, supporting Takeda's goal of producing 100 million doses globally each year by the end of the decade.

A minimally invasive treatment that targets only cancerous tissue in the prostate may offer the same chance of treating localized prostate cancer as surgery or radiotherapy while causing significantly fewer side effects, according to a major UK study.

The findings suggest that focal therapy, which destroys only the tumor while preserving the healthy parts of the prostate, could become a viable treatment option for carefully selected patients.

It could help reduce common risks like urinary incontinence and erectile dysfunction that follow conventional treatment.

Prostate Cancer Treatment With Fewer Side Effects

The study, presented by University College London (UCL) and collaborating institutions, compared long-term outcomes of men treated with focal therapy against those receiving radical prostatectomy or radiotherapy.

Researchers found that cancer control was comparable across the treatment groups, while men undergoing focal therapy experienced substantially better functional outcomes.

"This study shows that men with localized prostate cancer do not necessarily have to choose between effective cancer treatment and preserving their quality of life," said Professor Caroline Moore, Professor of Urology at University College London.

"Our results demonstrate that focal therapy can control cancer effectively in appropriately selected men while significantly reducing the side effects associated with whole-gland treatments."

Unlike surgery, which removes the entire prostate, or radiotherapy, which treats the whole gland, focal therapy targets only the cancer with the help of high-intensity focused ultrasound (HIFU). By sparing healthy tissue and surrounding nerves, the treatment aims to preserve urinary and sexual function.

According to the researchers, the study provides strong evidence that focal therapy can offer outcomes similar to standard treatments in men whose cancer is confined to a specific area of the prostate.

Not Appropriate For Every Patient

Professor Moore cautioned that focal therapy for prostate cancer may not be suitable for every patient. "It is important that men undergo careful assessment with high-quality imaging and biopsy so that we can identify those who are most likely to benefit from this treatment," she said.

The researchers also emphasized that patients receiving focal therapy require ongoing follow-up, including prostate-specific antigen (PSA) testing and imaging, to monitor any recurrence or progression of disease.

Jeremy Clarkson's Revelation

The findings have drawn renewed public attention after television presenter Jeremy Clarkson recently disclosed that he underwent treatment for prostate cancer.

Clarkson revealed that he chose a treatment that reduced long-term side effects, raising awareness about prostate cancer, and the importance of early diagnosis.

Prostate cancer is among the most commonly diagnosed cancers in men worldwide. While surgery and radiotherapy remain the standard treatments for localized disease, both can result in complications like urinary leakage, bowel problems and erectile dysfunction that can affect the quality of life.

Experts say the new findings support a growing shift toward more personalized treatment strategies that balance cancer treatment with quality of life.
