Yaso-GEL

Polyphenylene carboxymethylene (PPCM) is a polymer derived from mandelic acid. PPCM polymer has been extensively evaluated by several major laboratories and is a promising candidate for inhibiting sexually transmitted infections (STIs), contraception, and potentially airborne viral infections. PPCM will be used in topical applications as a vaginal gel.

Development Stage:

Clinical – Phase 0 Trial (C0)

Hormonal/Non-Hormonal:

Non-Hormonal

Delivery Route & Method:

Topical - Gel-Vaginal

Mechanism of Action:

PPCM prevents viral binding and fusion to a host cell by attaching to and blocking key viral binding sites. It has been demonstrated that PPCM binds gB on HSV-2 and gp120 on HIV. PPCM has also shown promise against Ebola virus in vitro and gonorrhea, in vitro and in mice. PPCM renders sperm infertile without damaging other cells.
