What this research studies

This project is developing ZB-06, a thin vaginal film that contains a monoclonal antibody (HCA) which binds a sperm surface protein (CD52g) so sperm clump and get trapped in mucus. The film is intended to be used about 30 minutes before intercourse and early post-coital tests show a large drop in the number of progressively motile sperm reaching the cervix. Earlier work on a similar film (MB66) showed it was safe and that vaginal samples could neutralize HIV and HSV in laboratory tests. The Industrialization Project focuses on manufacturing, product development, and preparing this approach for larger clinical trials and eventual commercialization.

Who could benefit from this research

Good fit: Women interested in a woman-controlled, on-demand non-hormonal contraceptive and who meet early-phase clinical trial eligibility would be the ideal candidates.

Not a fit: People seeking permanent sterilization, those who cannot or prefer not to use vaginal products, and pregnant individuals would not benefit from this product.

Why it matters

Potential benefit: If successful, it could provide a non-hormonal, on-demand contraceptive under a woman's control that may also offer protection against HIV and other STIs.

How similar studies have performed: Prior Phase 1 work with the MB66 antibody film showed good safety and ex vivo neutralization of HIV and HSV, and early ZB-06 results show promising reductions in motile sperm, but larger trials are still needed.
