Condition(s) targeted: Cervical Intraepithelial Neoplasia

Intervention: HAL 5% with illumination (Drug); HAL 1% with illumination (Drug); HAL 0.2% with illumination (Drug); Placebo ointment without illumination (Drug)

Phase: Phase 2

Status: Completed

Summary

An effective and safe medical therapy would be most welcome to reduce the need for surgical interventions and related adverse events and psychological impact on patients with cervical cancer precursors. In this clinical trial, the investigators propose to evaluate the efficacy and safety of photodynamic therapy (PDT) using hexaminolevulinate (HAL) for mild to moderate-grade CIN (grade 1-2).

Clinical Details

Official title: A Randomized Phase II Dose-finding Study of Hexaminolevulinate (HAL) Photodynamic Therapy (PDT) in Patients With Low/Moderate-grade Cervical Intraepithelial Neoplasia (CIN1 or 2)

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Comparison of Lesion Response Rates of Three Different Doses of HAL PDT and Placebo at 3 Months After Treatment.

Secondary outcome: Comparison of HPV Response of Three Different Doses of HAL PDT and Placebo at 3 Months After Treatment.
