Amphora/QGriffithsin (QGRFT) fast-dissolving vaginal insert (FDI)
Multipurpose Vaginal pH Regulator (MVP-R™) with non-ARV (anti-retroviral) microbicide for the prevention of pregnancy, HIV, and other STIs.
Preclinical – Early (Pre1)
Delivery Route & Method:
Topical - Fast Dissolving Insert/Capsule-Vaginal
Mechanism of Action:
Amphora lowers vaginal pH (pH = 3.5-4.5) in the presence of semen. The low pH inactivates sperm and bacteria. Gel coats vaginal and cervical mucosa and prevents sperm penetration. QGRFT is a potent non-ARV inhibitor of HIV. QGRFT binds to HIV envelope glycoproteins and prevents entry of HIV into target cells.
