Vaginal antiviral capsule to treat cervical precancer

RepurPosed AntiretrOviraL ThErapieS to EliminAte Cervical Cancer (POLESA Trial)

NIH-funded research University of Cincinnati · NIH-11414851

What this research studies

If I join, I would self-insert a vaginal capsule that delivers lopinavir/ritonavir in a new 12:1 ratio for a short course of 7, 14, or 21 days depending on the dose group. The pilot enrolls 15 women with cervical precancer (CIN2/3) at a colposcopy clinic in Cincinnati, OH as a Phase 1a/1b safety and acceptability study. Clinic visits will check for side effects, how easy the capsule is to use, and early signs that the treatment is acting on HPV or the precancer. Doctors will collect exams and lab tests to look for healing, HPV changes, bleeding, or other adverse effects during follow-up.

Who could benefit from this research

Good fit: Women diagnosed with cervical intraepithelial neoplasia grade 2 or 3 (CIN2/3) who can travel to the Cincinnati colposcopy clinic and are willing to self-administer a vaginal capsule would be the ideal candidates.

Not a fit: People with invasive cervical cancer or those who require immediate surgical treatment are unlikely to benefit from this pilot.

Why it matters

Potential benefit: If successful, this could offer a non-invasive, self-administered option that avoids surgery and may reduce pain, bleeding, scarring, and fertility risks.

How similar studies have performed: A prior proof-of-concept trial using a different lopinavir/ritonavir ratio reported promising results and laboratory studies support the approach, but the 12:1 capsule formulation is newly tested in humans.
