About this study
Official title: A Single Center, Phase I Study to Follow-up on the Change of Immunogenicity and Lesion Condition in Subjects Who Have Completed the Phase I GX-188E Trial (Protocol no. GX-188E-SN)
This study is to follow up on the change of immune response by measuring HPV type 16/18 E6 and E7 specific T cell response and lesion condition in subjects who have administered in DNA-based therapeutic vaccine.
Read the detailed description
This is a follow-up study to investigate the change of immunogenicity and lesion condition in subjects with cervical intraepithelial neoplasia (CIN) 3 who have enrolled and completed GX-188E phase I study.
Subjects will make visits at week 48 (V1) to week 228 (V8) every 6 months after the final administration of GX-188E.
The endpoints are to evaluate the change of immune response, involved lesion and infection status compared to that of the final visit in phase I study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GX-188EBiological
Also called GX-188E administerd by eletrophoration
In phase I study, 9 patients were assigned to three dose groups (1mg, 2mg and 4mg) and were administered three times with GX-188E by electroporation during an entire period of study. After the final administration, the follow-up will be conducted to investigate safety and efficacy aspects.

|---|---|---|
| Observational group | Subjects in the period less than 48 weeks after the final administration of GX-188E Receives: Biological: GX-188E |
What is being measured
The primary outcome is the main question the study is designed to answer.
The change of the immune response compared to that of the final visit in phase I study
It would be determined by evaluating HPV type 16/18 E6 and E7 specific T cell response (IFN-γ ELISPOT assay) using PBMC obtained at week 0 to 180 visit every 6 months.
Measured: at week 0 to 180 every 6 months
Secondary outcomes (2)
The change of the involved lesion and HPV infection status
The changes of histological test, cytological test and HPV infection status would be compared to that of the last visit in phase I study
Measured: at week 0 to 180 every 6 months
Safety profile
Safety profile would be examined by vital signs, physical examination, clinical laboratory tests etc
Measured: at week 0 to 180 every 6 months

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 South Korea. 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.
Are results available for this study?

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?
The change of the immune response compared to that of the final visit in phase I study (time frame: at week 0 to 180 every 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
