New vaccine combo aims to clear persistent HPV infection
NCT ID NCT03913117
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tests two vaccines designed to help the immune system fight HPV16, a virus linked to cervical cancer. The study includes 30 women with persistent HPV16 infection and mild cervical cell changes (ASC-US or LSIL). Participants receive a DNA vaccine followed by a protein vaccine boost, with the main goals being safety and finding the right dose.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pNGVL4aCRTE6E7L2 DNA vaccine and TA-CIN protein vaccine
- What this could lead to
- If successful, this could lead to a therapeutic vaccine that helps the immune system clear persistent HPV16 infection, potentially preventing progression to cervical cancer.
- What could go wrong
- This is a very early Phase 1 trial with only 30 participants, focused on safety and dosing. The vaccines may not produce a strong enough immune response to clear the virus, and side effects are unknown.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients with persistent (\>6 month period) ASC-US/LSIL determined by cervical cytology at study entry (ThinPrep with imaging) 2. Patients whose cytologic samples are persistent (\>6 month period) HPV16+ by Roche Cobas 4800, Roche Linear Array HPV Genotyping test or other FDA-approved HPV genotyping test at study entry. Co-infections with HPV types other than HPV16 are permissible for study entry. 3. Age ≥ 19 years 4. Baseline Eastern Cooperative Oncology Group 5. Patients must have adequate organ function at the time of enrollment as defined by the following parameters: * White blood cell count \> 3,000 * Absolute lymphocyte number \> 500 * Absolute neutrophil count \> 1,000 * Platelets \> 90,000 * Hemoglobulin \> 9 * Total bilirubin \<3 X the institutional limit of normal * AST(SGOT)/ALT(SGPT) \<3 X the institutional limit of normal * Creatinine \< 2.5X the institutional limit of normal 6. Women of child-bearing potential must agree to use two forms of contraception (hormonal and barrier) prior to study entry and for 3 months after study completion. 7. Ability to understand and the willingness to sign a written informed consent document. 8. Subject is able to adhere to the study visit schedule and other protocol requirements. Exclusion Criteria: 1. Patients with ASC-US/LSIL determined by cervical cytology at study entry that are HPV16 negative. 2. Histologic evidence of CIN2+ 3. Patients with a diagnosis of immunosuppression or prolonged, active use of immunosuppressive medications such as steroids. 4. Prior vaccination with any HPV antigen (prophylactic or therapeutic). 5. Patients who are receiving any other investigational agents within 28 days prior to the first dose. 6. Patients with an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. 7. Patients with a history of autoimmune disease such as multiple sclerosis, exclusive of a history of thyroiditis, psoriasis, Sjrogen's, or inflammatory bowel disease. 8. Patients with a history of allergic reactions attributed to compounds used in agent preparation. 9. Patients who are pregnant or breast feeding. 10. Patient with active or chronic infection of HIV, HCV, or HBV. 11. Patients who have had a prior LEEP or cervical conization procedure. 12. History of prior malignancy permitted if patient has been disease free for ≥ 5 years; however individuals with completely resected basal cell or squamous cell carcinoma of the skin within this interval may be enrolled. 13. Inability to understand or unwillingness to sign an informed consent document.
