What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new method to treat multiple strains of the human papillomavirus (HPV) by boosting the body's immune response. It combines the 9vHPV vaccine, which targets nine HPV strains, with the BCG vaccine, typically used against tuberculosis, to enhance immune activity. The goal is to determine if this combination can help the body more effectively attack and clear the HPV virus. Individuals with a cervical HPV infection, confirmed by a standard test and without symptoms, might be suitable for this study. As an Early Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this novel combination therapy.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research has shown that the 9-valent HPV (9vHPV) vaccine is generally safe and very effective. Studies have found that over 99.8% of recipients develop a strong immune response, helping the body fight off the virus.

The BCG vaccine, often used for tuberculosis, boosts the immune system. When combined with the 9vHPV vaccine, the goal is to enhance the body's ability to fight HPV infections.

Some side effects have been observed with the 9vHPV vaccine, including fainting, brain inflammation (encephalitis), and skin reactions like hives (urticaria). These side effects are rare, but it is important to be informed.

The combination of the 9vHPV and BCG vaccines remains under investigation. As this is an early phase trial, researchers are beginning to study how these vaccines work together in people. Safety is a top priority, and further studies are needed to fully understand how well people tolerate this vaccine mix. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about using a combination of the 9vHPV vaccine and the BCG vaccine to tackle Human Papillomavirus (HPV) because it offers a fresh approach. Most treatments for HPV focus on preventing infection with vaccines like the traditional HPV vaccines. However, this new treatment combines the 9vHPV vaccine with the BCG vaccine, which is typically used for tuberculosis, potentially boosting the immune response against HPV. The unique mix aims to enhance antigen presentation, which might improve the body's ability to target and eliminate HPV-infected cells. This novel approach could offer a more robust and comprehensive defense compared to standard vaccines alone.

What evidence suggests that the 9vHPV + BCG Vaccine Mix could be effective for HPV?

Research has shown that the 9-valent HPV vaccine (9vHPV) is highly effective, with a success rate of over 99.8% in helping the body produce antibodies against all types included in the vaccine. This enhances the immune system's ability to combat the HPV virus. Studies have found that the vaccine can reduce certain HPV infections and related health issues by up to 90%. In this trial, participants will receive a combination of the 9vHPV vaccine and the BCG vaccine, which might further boost the immune response. This combination aims to enhance the body's ability to recognize and fight HPV virus proteins. Early results suggest this method could more effectively clear the HPV virus from the body. ^{1 2 6 7 8}

Published Research Related to This Trial

The 9-valent HPV vaccine (Gardasil 9®) significantly increases protection against cervical cancer by covering 9 oncogenic HPV types, raising potential protection from about 70% to 90%, based on clinical trials involving young women.

Clinical trials demonstrated that the 9vHPV vaccine has a comparable safety profile and immunogenicity to the original 4-valent vaccine, with a 2-dose regimen showing similar effectiveness in younger boys and girls compared to the standard 3-dose regimen for older women.

Expanded strain coverage for a highly successful public health tool: Prophylactic 9-valent human papillomavirus vaccine. Zhang, Z., Zhang, J., Xia, N., et al.[2019]

The 9-valent HPV vaccine (9vHPV) is safe and highly effective, showing over 99.8% seroconversion rates for all vaccine types in both groups of a study involving 1054 participants aged 11-15 years.

Administering the 9vHPV vaccine alongside the REPEVAX vaccine did not interfere with the immune response to either vaccine, indicating that this approach can safely reduce the number of vaccination visits needed.

In a study of 569 postpartum inpatients, 23.1% of vaccine-eligible patients received the nine-valent HPV (9vHPV) vaccine during their hospital stay, indicating that integrating vaccination into postpartum care can increase uptake.

The study found that certain demographics, particularly Hispanic, Spanish-speaking, and publicly insured patients, were more likely to receive the vaccine, suggesting that targeted approaches in postpartum care could help reduce vaccination disparities.

The 9-valent HPV vaccine (9vHPV) can potentially increase the prevention of cervical cancer from 70% to 90% by covering additional HPV types (31, 33, 45, 52, and 58) not included in earlier vaccines.

In addition to cervical cancer, the 9vHPV vaccine could prevent 85-95% of HPV-related vulvar, vaginal, and anal cancers, highlighting its broad efficacy in reducing the overall cancer burden associated with HPV.

The 9-valent HPV vaccine (9vHPV) is highly immunogenic in females aged 12-26 who previously received the quadrivalent HPV vaccine (qHPV), with over 98% showing seropositivity for additional HPV types 31/33/45/52/58 after the third dose.

While injection-site adverse events were more common in the 9vHPV group (91.1%) compared to placebo (43.9%), systemic adverse events were similar between both groups, indicating that the 9vHPV vaccine is generally well tolerated.
