A Randomized Phase III Trial of Maintenance Chemotherapy Comparing 12, Monthly Cycles of Single Agent Paclitaxel or CT-2103 Versus No Treatment Until Documented Relapse in Women With Advanced Ovarian, Primary Peritoneal or Fallopian Tube Cancer Who Achieve a Complete Clinical Response to Primary Platinum/Taxane Chemotherapy
A Randomized Phase III Trial of Maintenance Chemotherapy Comparing 12, Monthly Cycles of Single Agent Paclitaxel or CT-2103 Versus No Treatment Until Documented Relapse in Women With Advanced Ovarian, Primary Peritoneal or Fallopian Tube Cancer Who Achieve a Complete Clinical Response to Primary Platinum/Taxane Chemotherapy
This randomized phase III trial studies paclitaxel to see how well it works compared to polyglutamate paclitaxel or observation only in treating patients with stage III or stage IV ovarian epithelial, peritoneal cancer, or fallopian tube cancer. Drugs used in chemotherapy, such as paclitaxel and polyglutamate paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Paclitaxel and polyglutamate paclitaxel may also stop the growth of ovarian epithelial or peritoneal cancer by blocking blood flow to the tumor. Sometimes, after treatment, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether paclitaxel is more effective than polyglutamate paclitaxel or observation only in treating ovarian epithelial, peritoneal, or fallopian tube cancer.
PRIMARY OBJECTIVES:
I. To determine whether CT-2103 (polyglutamate paclitaxel) or paclitaxel, administered to women with advanced ovarian, primary peritoneal or fallopian tube cancer who have attained a clinically-defined complete response to primary platinum/taxane-based chemotherapy ("consolidation/maintenance therapy") will reduce the death rate, compared to re-treatment at the time of documented disease progression.
II. To determine if, in this clinical setting, CT-2103 produces a more favorable toxicity profile (with a particular focus on peripheral neuropathy as measured by the Gynecologic Oncology Group [GOG] NTX4) and superior quality-of-life (as measured by the Functional Assessment of Cancer Therapy-Ovarian [FACT-O]), compared to paclitaxel.
SECONDARY OBJECTIVES:
I. To explore the relationship between expression of several of the angiogenic markers and overall survival or progression-free survival in patients randomized to CT-2103, paclitaxel, or no treatment.
II. To assess the association among the various tissue and serum markers of angiogenesis, and compare the ability of different combinations of these markers to predict patient outcome including overall survival and progression-free survival in patients randomized to CT-2103, paclitaxel, or no treatment.
III. To bank deoxyribonucleic acid (DNA) from whole blood for research and evaluate the association between single nucleotide polymorphisms (SNPs) and measures of clinical outcome including overall survival, progression-free survival and adverse events.
OUTLINE: Patients are randomized to 1 of 3 treatment arms.
ARM I: Patients receive polyglutamate paclitaxel intravenously (IV) over 10-20 minutes on day 1.
ARM II: Patients receive paclitaxel IV over 3 hours on day 1.
ARM III: Patients receive no further anticancer treatment until evidence of disease progression.
In arms I and II, treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 3 months for 2 years and then every 6 months for 10 years.

Platelet count >= 100,000/ul
Creatinine =< 1.5 times institutional upper limit of normal (ULN), CTCAE v3.0 grade 1
Bilirubin =< 1.5 times ULN, (CTCAE v3.0 grade 1)
Serum glutamic oxaloacetic transaminase (SGOT) =< 2.5 times ULN (CTCAE v3.0 grade 1)
Alkaline phosphatase =< 2.5 times ULN (CTCAE v3.0 grade 1)

Exclusion Criteria:
Patients with a current diagnosis of epithelial ovarian or fallopian tube tumor of low malignant potential (LMP) (Borderline carcinomas) are not eligible; patients with a prior diagnosis of a low malignant potential tumor that was surgically resected and who subsequently develop invasive adenocarcinoma are eligible, provided that they have not received prior chemotherapy for their ovarian LMP tumor
Germ cell tumors, sex cord-stromal tumors, carcinosarcomas, mixed mullerian tumors or carcinosarcomas, metastatic carcinomas from other sites to the ovary and low malignant potential tumors including so called micropapillary serous carcinomas are not eligible
Patients who have received prior radiotherapy to any portion of the abdominal cavity or pelvis are excluded; prior radiation for localized cancer of the breast, head and neck, or skin is permitted, provided that it was completed more than 3 years prior to registration, and the patient remains free of recurrent or metastatic disease
Patients who have received investigational therapies, and/or biological therapies (i.e. Bevacizumab or Erlotinib) for their epithelial ovarian, primary peritoneal or fallopian tube cancers or for any other abdominal or pelvic tumor, are not excluded; however, biologics cannot be continued concurrent with the GOG-012 maintenance treatment (or observation); patients who have received prior chemotherapy for any other abdominal or pelvic tumor (except as noted above) are excluded; patients may have received prior adjuvant chemotherapy for localized breast cancer, provided that it was completed more than 3 years prior to registration, and that the patient remains free of recurrent or metastatic disease
Patients with synchronous primary endometrial cancer, or a past history of primary endometrial cancer, are excluded, unless all of the following conditions are met:
With the exception of non-melanoma skin cancer and other specific malignancies as noted above, patients with other invasive malignancies who had (or have) any evidence of the other cancer present within the last 5 years or whose previous cancer treatment contraindicates this protocol therapy are excluded
Patients with acute hepatitis, or known chronic hepatitis
Patients with an active infection that requires antibiotics
Patients with ongoing gastrointestinal bleeding requiring blood product support
Patients whose circumstances at the time of entry onto the protocol would not permit completion of study or required follow up
Patients with unstable angina or those who have had a myocardial infarction within the past six months; patients with evidence of abnormal cardiac conduction (e.g. bundle branch block, heart block) are eligible if their disease has been stable for the past six months
Patients are excluded who have had prior therapy with CT-2103
