Clinical Trial Summary

The purpose of this clinical study is to confirm the utility of chemosensitivity (ChemoID) tumor testing on cancer stem cells as a predictor of clinical response in recurrent platinum resistant epithelial ovarian cancer (EOC), fallopian tube, or primary peritoneal cancer.

Population studied will be female participants experiencing a recurrent platinum-resistant ovarian cancer (no mucinous, low grade serous, or pure sarcoma types), with ≤ 5 prior treatments, and a performance status 0-1.

Description:

This study is designed as a parallel group randomized controlled clinical trial to determine if recurrent platinum resistant epithelial ovarian cancer (EOC) patients treated with chemotherapy predicted by the ChemoID assay will have better outcomes than patients treated with standard-of-care control therapy chosen by the physician.

Upon obtaining informed consent, all eligible participants affected by recurrent platinum-resistant ovarian cancer (no mucinous, low grade serous, or pure sarcoma types), with ≤ 5 prior treatments, and a performance status 0-1 will have a tumor biopsy or a cancer-positive fluid collection sample to undergo ChemoID drug response testing with multiple FDA-approved chemotherapeutic agents.

Eligible participants will be randomized to a standard treatment arm with control treatment (chemotherapy chosen by the Physician from a provided list), or to a study arm of FDA-approved drugs selected by the ChemoID drug response assay.

A stratified randomization approach for treatment arm assignment will be used with strata based on number of prior platinum treatments and BRCA status to ensure balance within these cells.

11. Participant must have an estimated life expectancy of greater than six months, as determined by the investigator.

12. Participant requires chemotherapy and the investigator plans to administer one of the regimens of interest as deemed by her physician.

13. Participant must have an ECOG Performance Status Score of = 2, KPS=70, or 0-2 GOG status.

14. Adequate laboratory values within 60 days of enrollment to study defined as follows:

1. ANC = 1500/mm3

2. Hgb = 10 mg/dl

3. Hct = 28%

4. Platelet count = 100,000/µL

5. Serum creatinine = 2.0 mg/dl

6. Total bilirubin = 2.5 mg/dl

7. AST/SGOT = 3 times ULN. If intrahepatic liver metastases are present, AST and ALT must be = 5 times institutional ULN.

Exclusion Criteria:

1. Use of Avastin planned to treat participant.

2. Participant has ovarian stromal, germ cell tumors or pure sarcomas.

3. Participant has borderline carcinoma (uncertain malignant potential), mutinous or low-grade serous carcinoma.

4. Participant is pregnant or lactating.

5. Participants of childbearing potential not employing adequate contraception.

6. Participants who are at risk of failure of compliance to the visit schedules and procedures including those with psychiatric disease that would substantially impact compliance or consent.

7. Estimated life expectancy of <6 months, as estimated by the investigator in consultation with participating oncologists.

8. Participants with symptomatic cardiac conditions (i.e. NYHA class III/IV or uncompensated angina).

9. Enrollment in another clinical study that precludes allowing the oncologist to select chemotherapy regimens.

10. Previously participated in this study.

11. Any condition that would, in the opinion of the investigator, place the participant at an unacceptable risk, or render the participant unable to meet the requirements of the protocol (including long-term study follow-up).

12. CA-125 only disease without RECIST 1.1 measurable or otherwise evaluable disease.

13. Patients with third space fluid (for example pleural effusions) as only site of disease.

14. Participant may not use any complementary or alternative medicines including natural herbal products or folk remedies as they may interfere with the effectiveness of the study treatments.

Intervention

Diagnostic Test:
• ChemoID Assay
The ChemoID test is a CLIA-certified and CAP-accredited drug response assay performed by a hospital clinical pathology laboratory that uses patient's live tumor cells to indicate which chemotherapy agent (or combinations) will kill bulk of tumor cells, and cancer stem cells (CSCs) that are known to cause cancer to recur. During the assay, cancer stem cells and bulk tumor cells from an individual patient are exposed to FDA-approved chemotherapy drugs. The test measures the cytotoxic effect of actual doses of standard-of-care chemotherapies. The ChemoID drug response assay reports a prioritized list of effective and ineffective chemotherapies. The test is designed to target cancer stem cells to mitigate tumor relapse.

Drug:
• Standard Chemotherapy
Control chemotherapy treatment will be chosen from any of the following standard-of-care chemotherapy drugs or combinations: Liposomal Doxorubicin; Docetaxel; Paclitaxel; Carboplatin; Cisplatin; Gemcitabine; Topotecan; Carboplatin, Gemcitabine; Cisplatin, Gemcitabine; Carboplatin, Liposomal Doxorubicin; Carboplatin, Paclitaxel; Carboplatin, Docetaxel. The treating physician will NOT receive the ChemoID assay results from the ChemoID lab.
