Could a Light-Activated cream replace surgery for cervical precancer?
NCT ID NCT07669363
First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 6 times
Summary
This study tests a new approach for treating high-grade cervical precancer (HSIL) using a cream called HAL that is activated by a special light, instead of standard surgery. About 230 women will be randomly assigned to receive either the light therapy or surgery. The main goal is to see if the cream can clear the abnormal cells as effectively as surgery, while possibly being gentler and preserving fertility.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hexaminolevulinate hydrochloride (HAL) 5% ointment with light therapy
- What this could lead to
- If successful, this could offer a non-surgical, outpatient option for treating cervical precancer, potentially preserving fertility and reducing recovery time.
- What could go wrong
- This is an early Phase II trial with only 230 participants, so results may not apply broadly. The treatment may not be as effective as surgery, and there is a small risk of progression to cancer if it fails.

Inclusion Criteria: * Voluntarily participate in this clinical study, fully understand the study content, procedures, and potential adverse reactions, and be able to sign the written informed consent form. * Able to complete the study in accordance with the study protocol. * Subject age ≥18 years. * Presence of High-Grade Squamous Intraepithelial Lesion (HSIL) (CIN2 P16 positive/CIN3), specifically: HSIL with histopathological diagnosis of grade II/III (CIN2 P16 positive/CIN3) within 3 months prior to the first treatment. * Adequate colposcopy, including: (a) Complete visibility of the cervical transformation zone, including the squamocolumnar junction; (b) Complete visibility of lesion margins. * The investigator determines that non-surgical treatment is acceptable for the participant. * The investigator determines that the cervical size is suitable for placement of the HAL-PDT device. * Meets the following conditions: Women of childbearing potential (WOCBP) must have a negative serum pregnancy test result prior to the start of treatment. No plan for pregnancy during the study period; no sexual activity or use of effective and reliable contraception from the end of the last menstrual period to the start of the study, and agreement to use condoms for barrier contraception during the study period. WOCBP is defined as a female who has experienced menarche, has not undergone hysterectomy or bilateral oophorectomy, and has not reached natural menopause (i.e., no menstruation at all for the past 24 consecutive months). Exclusion Criteria: * Cervical adenocarcinoma in situ or other glandular lesions, invasive cervical cancer, or suspected malignant lesions. * CIN2 with P16 negative. * Lesions extending to the vaginal wall, cervical canal, or vaginal fornix, or lesions located on the vulva. * Prior physical or surgical treatment to the cervix resulting in incomplete cervical structure (e.g., cold knife conization), or receipt of physical or surgical therapy for CIN2 or CIN3 after the current histopathological diagnosis. * The first study treatment day falls within 7 half-lives of the last antiviral medication. * Severe pelvic inflammatory disease, severe cervicitis, or other severe gynecological infectious diseases found on colposcopic or clinical examination. * Investigator judges that vaginal bleeding during treatment may affect treatment outcomes. * Receipt of any inactivated vaccine within 2 weeks prior to the first treatment, or any live vaccine within 4 weeks prior to the first treatment. * Previous severe cardiovascular, cerebrovascular, neurological, psychiatric, endocrine, or hematopoietic disease that has not been cured; known severely compromised immune function, or need for long-term use of corticosteroids or immunosuppressants; history of malignancy within 5 years. * History of clinically significant immunosuppression or confirmed autoimmune disease; or primary immunodeficiency. * Known or newly identified active sexually transmitted diseases (STDs), including but not limited to HIV, syphilis, genital herpes, unless adequately treated and tested negative before study treatment. * Presence of a cardiac pacemaker. * Suspected or known porphyria, or known allergy to the study drug, its chemically similar compounds, or photosensitizers. * Allergy to silicone. * Pregnant or breastfeeding women. * Delivery or miscarriage within 6 weeks prior to enrollment. * Participation in any other clinical trial within 30 days prior to study treatment. * Poor compliance or judged by the investigator to be unsuitable for participation in this clinical study.
