Trial summary

This research study is being carried out to study a new way to possibly treat human cervical intraepithelial neoplasia (CIN) without invasion. Persistent infection with specific types of human papillomavirus (HPV, most frequently types 16 and 18) may lead to precancerous lesions(CIN). Read more about this study

About this study

Official title: Safety Study of Zinc Finger Nucleases ZFN-602 and ZFN-758 in HPV-infected Subjects

This research study is being carried out to study a new way to possibly treat human cervical intraepithelial neoplasia (CIN) without invasion.

Persistent infection with specific types of human papillomavirus (HPV, most frequently types 16 and 18) may lead to precancerous lesions(CIN). If untreated, these lesions may progress to cervical cancer within many years. In the infected cells, HPV expresses the oncoproteins E6 and E7, both of which play key roles in maintaining viral infection and promoting carcinogenesis. Previous studies has demonstrated that E7 alone, but not E6, is sufficient to immortalize human keratinocytes in vitro and induce high-grade cervical dysplasia in a transgenic mouse model. These data indicated that E7 may dominate the malignant progress in HPV-infected cells.

The agents zinc finger nucleases (ZFNs), called ZFN-603 and ZFN-758, which can cleave the HPV16 and HPV18 E7 oncogene specifically. ZFN-mediated disruption of HPV16 and HPV18 E7 DNA directly decreased the expression of E7, induced type-specific apoptosis in HPV16- and HPV18-positive cells, and inhibited cell growth.

The purpose of this study is to determine whether ZFN-603 and ZFN-758 are effective in the treatment of HPV16- and HPV18-positive cervical intraepithelial neoplasia.

Read the detailed description

Laboratory studies have shown that ZFN-603 and ZFN-758 could induce significant cleavage of E7 DNA in HPV16- and HPV18-positive cells. The disruption to viral DNA directly led to downregulation of E7 expression and restoration of the tumor suppressor genes retinoblastoma 1 (RB1), resulting in apoptosis and growth inhibition of ZFN-treated HPV16- and HPV18- positive cell lines. On the basis of these laboratory results, there is the potential that this may work in humans infected with high-risk HPV (especially HPV16 and HPV18) and block the progression of CIN The new treatment to be studied will involve transfecting ZFNs into HPV-infected cervical epithelials. Cells modified by ZFN-603 and ZFN-758 will lose the ability of immortalization and progress to apoptosis.

Researchers hope that these agents will be able to block the malignant progression of CIN and reduce the incidence of cervical cancer

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety - Treatment related adverse events of ZFN-603 in HPV16-positive subjects, related adverse events of ZFN-758 in HPV18-positive subjects

    Number of participants who report adverse events as a measure of safety

    Measured: 6 months

Secondary outcomes (3)
  1. Evaluate persistence of HPV16 and HPV18 as measured by HPV DNA

    Reduce the virus titers after using ZFN-603 and ZFN-758

    Measured: 6 months

  2. Change in the number of dysplastic cells as mearsured by ThinPrep Pap Test

    From high-grade squamous intraepithelial lesion (HSIL) to Low-grade Squamous Intraepithelial Lesion (LSIL), or from LSIL to negative.

    Measured: 6 months

  3. Number of participants with Regain health or without progress

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ZFN-603 and ZFN-758 in people with Human Papillomavirus-Related Malignant Neoplasm, run by Huazhong University of Science and Technology at 1 site in China.

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 4 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 12 Jul 2017. 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 China. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Results are not available in the source record.

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?

Safety - Treatment related adverse events of ZFN-603 in HPV16-positive subjects, related adverse events of ZFN-758 in HPV18-positive subjects (time frame: 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 NCT02800369, which also lists 1 linked publication.

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 12 Jul 2017.
