About this study
The aim of this study is the safety and efficacy of cryosurgery plus NK immunotherapy to recurrent ovarian cancer.
Read the detailed description
By enrolling patients with recurrent ovarian cancer adapted to enrolled criteria, this study will document for the first time the safety and the short and long term efficacy of the combined therapy using cryosurgery and natural killer (NK) cells.
The safety will be evaluated by statistics of adverse reactions. The efficacy will be evaluated according to local relief degree, progress free survival (PFS) and overall survival (OS).
- Conditions
- Recurrent Ovarian Cancer
- Being tested
- Cryosurgery, NK immunotherapy
- Keywords
- Ovarian Cancer, cryosurgery, NK immunotherapy
- Medical subject headings
- Ovarian Neoplasms
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CryosurgeryDevice
Also called Argon-helium cryosurgical system
Percutaneous ablation under CT or ultrasound guidance
NK immunotherapyBiological
Each treatment: 8~10 billion cells in all, transfuion in 3 times, i.v.
| Study group | Role | What they receive |
|---|---|---|
| Cryosurgery and NK immunotherapy | Experimental | In this group, the patients will receive comprehensive cryosurgery to clear all big tumors and then receive multiple NK immunotherapies. The check indexes are CT scan and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell). Receives: Device: Cryosurgery; Biological: NK immunotherapy |
| Cryosurgery | Active comparator | In this group, the patients will receive comprehensive cryosurgery to clear all big tumors. The check indexes are CT scan and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell). Receives: Device: Cryosurgery |
What is being measured

It will be evaluated by the Response Evaluation Criteria in Solid Tumors（RECIST）
Measured: 3 months
Secondary outcomes (2)

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Cryosurgery and NK immunotherapy in people with Recurrent Ovarian Cancer, run by Fuda Cancer Hospital, Guangzhou 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 3 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: finished, as of the sponsor's last update on 12 Sep 2019. 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 combined 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.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Relief degree of tumors (time frame: 3 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 Sep 2019.
