Trial summary

This phase II trial studies the effect of pembrolizumab on cervical intraepithelial neoplasia. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Note: no testing for hepatitis B and hepatitis C is required unless mandated by local health authority
  • Has a known history of active TB (Bacillus tuberculosis)
  • Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
  • Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial

About this study

Official title: A Phase II Open-Label, Single Arm Pilot Study to Evaluate the Safety and Efficacy of Pembrolizumab for High-Grade Cervical Intraepithelial Neoplasia

This phase II trial studies the effect of pembrolizumab on cervical intraepithelial neoplasia. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Read the detailed description

PRIMARY OBJECTIVE:

  1. Proportion of subjects with pathologic complete response (no evidence of dysplasia).

SECONDARY OBJECTIVES:

  1. Safety and tolerability of pembrolizumab in subjects with cervical intraepithelial neoplasia (CIN).

II. Proportion of subjects with pathologic partial response (regression to a lower grade of dysplasia).

EXPLORATORY OBJECTIVES:

  1. Evaluation of Programmed Death-Ligand 1 (PD-L1) expression in CIN lesions as a biomarker of response to therapy.

II. Evaluation of Human Papillomavirus (HPV) status as a biomarker of response to therapy.

III. Evaluation of HPV clearance as a surrogate endpoint.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 6 weeks for 4 cycles (24 weeks).

Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pembrolizumab in people with Cervical Intraepithelial Neoplasia and Cervical Squamous Cell Carcinoma In Situ, run by Jonsson Comprehensive Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 6 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological response rate (time frame: At 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04712851.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2026.
