What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is evaluating a new vaginal film called KB15A, which contains an antibody designed to prevent sperm from functioning. The main goal is to assess its safety and how it behaves in the body compared to a placebo (a treatment with no active ingredients). Researchers seek healthy women aged 18 to 45 with regular menstrual cycles who are willing to use condoms during the study. Participants should not have major health issues or be pregnant, and they should be in a committed relationship with a partner free from STIs (sexually transmitted infections). As a Phase 1 trial, participants will be among the first to help researchers understand how this new treatment works in people.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you must not have used oral or vaginal antibiotics in the last 14 days before joining the study.

Is there any evidence suggesting that KB15A is likely to be safe for humans?

Previous studies have shown that KB15A, a vaginal film with an anti-sperm antibody, is safe and well-tolerated. Research indicates that users found the film acceptable, with no major side effects reported. Additionally, the study found no long-term increases in certain proteins that could indicate inflammation after using the film. This suggests that KB15A is generally safe for human use.12345

Why do researchers think this study treatment might be promising?

Researchers are excited about KB15A because it's a vaginal film, which is a new and convenient delivery method compared to current options like oral medications or creams. This film dissolves directly at the site of action, potentially offering faster and more targeted relief. Unlike other treatments that might have systemic side effects, KB15A's localized application could minimize those risks, making it a promising advancement in women's health.

What evidence suggests that KB15A might be an effective treatment for contraception?

Research shows that KB15A, a vaginal film with an anti-sperm antibody, maintains effective antibody levels in the vagina for at least 3 hours after use. This suggests the film might temporarily block sperm after application. In this trial, participants will receive either the KB15A film or a placebo film. Studies on similar films, such as MB66, have found them to be safe and well-tolerated by users. Although exact data on pregnancy prevention is not yet available, the method of antibody delivery appears promising. Ongoing research aims to confirm these early results and ensure the product's safety for users.13467

Are You a Good Fit for This Trial?

This trial is for healthy adult women aged 18-45 who are willing to use condoms and abstain from other vaginal products during the study. They should have no significant systemic diseases, regular menstrual cycles (if not on hormones), and be able to provide informed consent.
