Blood samples and Tumor tissue will be collected at certain timepoints and will be tested.
Blood samples will be tested by Natera to identify residual tumor DNA for genetic changes in the tumor to potentially improve prediction of long term prognosis and guide treatment options.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Females with Stage II-IV epithelial ovarian cancer | All patients, as participation requirements in this study, are required to have blood drawn at the completion of their adjuvant treatment. Blood sample should be collected within 6 weeks of receiving the last cycle of adjuvant chemotherapy. Other optional time points which will be encouraged but not required:

|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Signatera testing | Diagnostic Test | 26mL blood for the first blood draw and tissue sample. 20mL blood all subsequent draws. |
|
| Measure | Description | Time Frame |
|---|---|---|
| To assess the effect of a negative Signatera MRD test on progression free survival (PFS) compared to Signatera MRD testing positive patients. | The Signatera MRD test measures the amount of circulating tumor DNA(ctDNA). We seek to assess the effect of a negative versus positive test on PFS. PFS will be measured in months from the time of last platinum adjuvant chemotherapy to objective disease progression on imaging according to RECIST 1.1 or death from any cause | Signatera MRD testing done within 6 weeks of finishing adjuvant therapy |
| Measure | Description | Time Frame |
|---|---|---|
| To assess the effect of the amount of residual tumor after surgery as defined by Signatera MRD testing on length of PFS | We seek to assess if the amount of residual tumor detected on Signatera MRD testing correlates with length of PFS. Similarly, does an undetectable ctDNA level versus detectable level (by Signatera MRD testing) have different lengths of PFS. PFS will be measured in months from the time of last platinum adjuvant chemotherapy to objective disease progression on imaging according to RECIST 1.1 or death from any cause. |

Residual Material for the purpose of validation, quality assurance, and correlation of results, including for regulatory, reimbursement and patent filings, to the extent the foregoing is related or pertains to the results of the research project and the Signatera assay, which is used to perform the research project.
| Altera Testing | Diagnostic Test | 6ml blood and tissue sample. |

| To assess the effect of negative Signatera MRD testing on the length of overall survival (OS) as compared to Signatera MRD testing positive patients | This outcomes seeks to assess if a negative Signatera MRD test has a significantly different OS compared to patients with a positive Signatera MRD test. OS will be measured in months from the time of last platinum adjuvant chemotherapy to death from any cause. | Signatera MRD testing done within 6 weeks of finishing adjuvant therapy |
| To assess the effect of negative Signatera MRD testing on the length of PFS in patients treated with PARP inhibitors (PARPi) compared to Signatera MRD testing positive patients. | We seek to assess the effect of a negative Signatera MRD test on PFS in patients that are treated with PARPi compared to patients with a positive Signatera MRD test. PFS will be measured in months from the time of last platinum adjuvant chemotherapy to objective disease progression on imaging according to RECIST 1.1 or death from any cause. | Signatera MRD testing done within 6 weeks of finishing adjuvant therapy |
| To assess if recurrent ovarian cancer is detectable earlier by a rise in ctDNA (by Signatera MRD testing) compared to a rise in CA-125. | We seek to assess if Signatera MRD testing will show an increase in ctDNA levels prior to a rise of CA-125 above the normal range. | Patients will be measured by Signatera MRD testing within 6 weeks of completing adjuvant treatment and every 3 months for up to 2 years. CA-125 will be measured every 3 months until progressive disease or death. |
| To assess if recurrent ovarian cancer is detectable earlier by a rise in ctDNA (by Signatera MRD testing) compared to radiographic method (objective disease progression by RECIST 1.1). | We seek to assess if Signatera MRD testing will show an increase in ctDNA levels prior to objective disease progression by RECIST 1.1 | Signatera MRD test within 6 weeks of completing adjuvant treatment and every 3 months for up to 2 years. CT every 3 cycles(1 month cycles) while on maintenance or CT for abnormal CA-125, patient symptom, or clinical exam abnormality on surveillance |
| To assess if recurrent ovarian cancer is detectable earlier by a rise in ctDNA (by Signatera MRD testing) compared to recurrence as assessed by the investigator. | We seek to assess if Signatera MRD testing will show an increase in ctDNA levels prior to the diagnosis of recurrent disease as assessed by physician evaluation. The physician may use all available clinical information in this determination. | Patients will be measured by Signatera MRD testing within 6 weeks of completing adjuvant treatment and every 3 months for up to 2 years. Physician assessment wil be as per normal surveillance schedule of the investigator. |
| To assess the effect of maintenance therapy (PARPi or bevacizumab) on the rate of negative Signatera MRD testing as compared to patients not given maintenance therapy. | We seek to assess if patients will be more likely to achieve a negative Signatera MRD test if they are given maintenance therapy as compared to surveillance. | Signatera MRD test within 6 weeks of completing adjuvant treatment and every 3 months for up to 2 years. |
| We seek to determine if patients assessed with whole exome sequencing (Altera) will show different genetic mutational patterns than those who are Signatera MRD testing positive and negative. | We seek to assess if there are differences in genetic mutations (e.g. BRCA, RAD51, BRIP1, p53, MLH1, PMS2, MSH2 and 6 etc.) between patients that are found to be Signatera MRD testing positive or negative. | Signatera MRD testing done within 6 weeks of finishing adjuvant therapy. Altera testing will be done on the tumor and blood sample provided at enrollment. |
| We seek to determine if patients assessed with whole exome sequencing (Altera) will show different genetic mutational patterns than those who are PARPi and bevacizumab maintenance therapy responders | We seek to assess if there are differences in genetic mutations (e.g. BRCA, RAD51, BRIP1, p53, MLH1, PMS2, MSH2 and 6 etc.) between patients that are found to be PARPi and bevacizumab maintenance responders | Altera testing will be done on the tumor and blood sample provided at enrollment. |
| We seek to determine if patients assessed with whole exome sequencing (Altera) will show different genetic mutational patterns when compared by debulking status. | We seek to assess if there are differences in genetic mutations (e.g. BRCA, RAD51, BRIP1, p53, MLH1, PMS2, MSH2 and 6 etc.) between patients whose debulking results in no gross residual disease, optimal debulking or suboptimal debulking | Altera testing will be done on the tumor and blood sample provided at enrollment. |
