2. Adequate colposcopy including:

1. visualization of entire cervical transformation zone including the squamocolumnar junction

2. visualization of entire lesion margin

3. Colposcopically visible lesion after biopsy, before treatment (Note: To ensure a colposcopically visible lesion after biopsy, the lesion should cover approximately 15% of the uterine cervix before biopsy)

2. Invasive cervical cancer

3. Adenocarcinoma in situ, or other glandular intraepithelial lesions

4. Lesion(s) extending to the cervical canal (as clinically indicated and whether to perform endocervical curettage [ECC] test at the discretion of the investigators)

5. Lesion(s) extending to the vaginal vault

6. Current severe pelvic inflammatory disease, severe cervicitis, or other severe gynecological infection as per colposcopy and clinical examination

7. Vaginal bleeding at time of treatment at the discretion of the investigator

8. Pregnancy

9. Nursing

10. Childbirth or miscarriage within six weeks of enrolment

11. Patients who previously received surgical treatment, have incomplete cervical structure and have recurrent HSIL; or patients who received other treatment after the confirmed diagnosis of HSIL

Intervention

Combination Product:
• Cevira®
The device is a single-use, disposable, LED-based red light source. The device will automatically switch on the light 5 hours after administration, and provide continuous photoactivation of 125 J/cm2 over 4.6 hours before automatically shutting down.
• Placebo
The placebo device is identical in appearance as the Cevira® device, but does not provide light.
