About this study

Official title: Evaluation of Prognostic and Predictive Values of Bespoke Circulating Tumor DNA Assay for Recurrent and Response Monitoring in Patients With Advanced Epithelial Ovarian Cancer

This prospective observational study is to assess the dynamics of circulating tumor DNA (ctDNA) in patients with advanced epithelial ovarian cancer (EOC) undergoing surgery, adjuvant chemotherapy, followed by poly adenosine diphosphate-ribose polymerase (PARP) inhibitors until disease progression or the end of the study. All patients will be closely monitored throughout the course of disease by a tumor-informed bespoke ctDNA assay as well as traditional methods of surveillance, such as CA125 and imaging. This study may provide preliminary evidence for ctDNA-guided treatment decisions in future clinical practice.

Read the detailed description

This observational study is designed for exploring prognostic and predictive values of the tumor-informed bespoke ctDNA assay in advanced EOC. Newly diagnosed patients who are eligible for radical surgery or relapsed patients from platinum-based adjuvant chemotherapy who are eligible for secondary cytoreductive surgery will be enrolled. The patients will be treated with SOC adjuvant therapies followed by PARP inhibitor for maintenance.

To evaluate ctDNA dynamics, tumor tissue collected from surgery will be sequenced with whole-exome sequencing (WES) to design patient-specific 16-plex panel. At planned monitoring timepoints, blood samples will be drawn, and ctDNA will be sequenced with ultra-deep ctDNA high-throughput sequencing methods.

Traditional surveillance methods will be applied as comparison, including but not limited to carbohydrate antigen 125 (CA-125)/ human epididymal protein 4 (HE4)/ carcinoembryonic antigen (CEA)/ carbohydrate antigen 199 (CA199), etc., as well as standard imaging.

Survival analyses will be conducted based on ctDNA status (positive/negative) after surgery. Recurrence rate of each subgroup, positive predictive values and negative predictive values etc. will be examined. Changes in ctDNA levels (ΔctDNA) during treatment will be used to evaluate the efficacy of maintenance therapy comparing traditional biomarkers,

Questions about this trial

What is this clinical trial studying?

An observational study of Ovarian Cancer, run by Fudan University 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 5 inclusion and 5 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: looking for participants now, as of the sponsor's last update on 28 Dec 2023. 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.

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?

Contact Hao Wen, MD (+86-021-64175590 ext. 81000, wenhao@shca.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression free survival (PFS) (time frame: Two years). 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 28 Dec 2023.
