Ovarian Cancer Clinical Trial

Developing a Test for the Detection of Ovarian Cancer

Summary

The study aims to develop a test for early detection of ovarian cancer using DNA from a growth involving the ovary found in a washing of the uterus (womb), and proteins found in the blood. The samples of the wash and the blood will be taken before surgery. After surgery, doctors will determine whether the participant had ovarian cancer or a benign disease of the ovaries. The tests of the washings and the blood will be examined to see how much the participants with ovarian cancer can be separated from the participants with a benign ovarian disease by the tests. Small amounts from the washing and the blood samples will be sent to four sites for analysis.

Statistical analyses of these data will compare tumor DNA found in the washing of the uterus with proteins in the blood to detect cases of ovarian cancer. The primary goal is to find tests that are mostly positive for cases of ovarian cancer and mostly negative for patients with benign disease. It is hoped that if the tests work for participants with symptoms of the disease that these tests will also work when testing women who have no symptoms. A new study would be needed to see if the tests worked in this situation. If the tests work, this could lead to increasing the number of cases detected in early stage disease and decreasing the number of cases detected in late stage disease. If this change in late stage is large, it will likely reduce deaths due to ovarian cancer.

Full Description

The study aims to elucidate the relative contributions to detection of ovarian cancer from tumor DNA in uterine lavage (UL) and protein biomarkers from blood using newly available detection and sample collection technologies. In this document, the term "ovarian cancer" includes fallopian tube cancer. In the first cohort, the study will enroll 200 participants. Enrolling participants prior to surgical diagnosis (e.g. laparoscopy or paracentesis) ensures the study will be "Prospective Collection of Samples, Blinded Evaluation" (PRoBE) compliant. The expectation is that ~50 of these participants will have pathologically confirmed ovarian cancer. In a second cohort, 50 participants will be enrolled. Based on published reports, it is expected that ~5 participants will have microscopic or low volume ovarian cancer. In each cohort, the participants with a pathologic invasive epithelial ovarian cancer diagnosis will be defined as Cases and participants without any ovarian cancer, primary peritoneal cancer (PPC), or other cancer identified due to the surgery, will be defined as Controls. Other cancer groups are: (i) PPC, (ii) non-invasive serous tubal intraepithelial carcinoma (STIC) lesions, (iii) non-epithelial ovarian cancers, and (iv) non-ovarian cancers.

Two sites will sequence DNA obtained from uterine lavages to detect tumor-derived DNA (tDNA): one will carry out Duplex Sequencing of TP53 and the second site will carry out Haloplex sequencing of an 18-gene panel. Two other sites will assay serum proteins: the first will use clinical grade assays for CA125 and HE4, and the second will use research grade assays for these two proteins plus four additional protein biomarker candidates. Statistical analyses of these data will evaluate the relative utility of tDNA and plasma proteins to detect Cases (sensitivity) while limiting detection of Controls (specificity) in these two cohorts. Remaining DNA from UL and blood based biospecimens in form of plasma, serum, and buffy coat will be stored at a biorepository at NCI Frederick for future biomarker investigations which include (but are not limited to) other methods of detecting tDNA from UL, tDNA from plasma, exosomal markers, and additional blood-based and UL biomarker candidates.

Primary objectives:

To collect samples from 200 participants with suspected ovarian cancer (of which ~50 or more are expected to have pathologically confirmed ovarian cancer) and 50 participants undergoing a risk-reducing salpingo-oophorectomy (of which ~5 are expected to have microscopic or low volume ovarian cancer).
To test the tDNA from uterine lavage samples for tumor-derived TP53 mutations, using Duplex sequencing, and for potential abnormalities in an 18-gene panel, using Haloplex sequencing
To test the serum proteins with two assays: the first will use clinical grade assays for CA125 and HE4, and the second will use research grade assays for these two proteins plus four additional protein biomarker candidates.

Outline: Participants undergo two blood draws (one required, one optional) up to 31 days before surgery and a uterine lavage at the time of planned surgery. The tDNA and serum proteins are then extracted from the samples and sent for analysis.

Eligibility Criteria

Inclusion Criteria:

Has intact uterus (no history of uterine ablation, tubal ligation or bilateral salpingectomy)
Cohort 1 (n=200 participants): Women scheduled for surgery or diagnostic laparoscopy for suspected but undiagnosed ovarian/fallopian tube cancer
Cohort 2 (n=50 participants): Known BRCA1 or BRCA2 mutation carrier scheduled for risk-reducing salpingo-oophorectomy

Exclusion Criteria:

Current tissue or cytology diagnostic procedure positive for ovary cancer or any cancer
Inability to provide informed consent
Age less than 30 years
Inability to obtain the minimum amount of blood
Inability to obtain the minimum amount of uterine lavage sample
At risk if blood were drawn (e.g. hemophilia, serious anemia- Hb less than 8.0 gm/dL)
Prior history of known ovarian or endometrial cancer
Treatment less than 1 year (excluding hormonal therapy) for cancer that spread beyond its origin
History of untreated high-grade cervical dysplasia (CIN3)
History of treated high grade cervical dysplasia (CIN3) with a cytologically abnormal pap smear within the past year. If there is no post treatment Pap smear in the medical record, perform a Pap smear prior to the day of surgery. If this Pap smear is abnormal, the participant is ineligible.
