About

This study is to determine the feasibility of postoperative platinum-based chemotherapy plus adjuvant and maintenance bevacizumab after neoadjuvant chemotherapy followed by interval surgery in patients with extensive stage IIIC or IV ovarian, tubal, and peritoneal cancer.

Full description

This study is designed to determine the feasibility of administering adjuvant carboplatin, paclitaxel, and bevacizumab without unacceptable significant AE in patients with epithelial ovarian cancer after neoadjuvant carboplatin/cisplatin, and paclitaxel and interval cytoreductive surgery, primary peritoneal cancer or fallopian tube cancer. This study will also investigate progression free and to assess the quality of life.

A Simon minimax two-stage design is employed to determine permit early stopping when a moderately long sequence of initial adverse events occurs. Under this two-stage design, 13 subjects are enrolled at the first stage. If there are > 3 subjects discontinue treatment due to significant AE in the stage-1, then stop the trial. Otherwise, the second stage is implemented by including the other 14 subjects. The treatment safety will be evaluated and ensured by the occurrence rate of significant AE (or non AE). In stage-1, postoperative adjuvant cycles 2-6 will be observed for defined significant AE.

Patients' or physicians' decision of discontinuation not because of the above-defined significant AEs or due to cancer progression should not be counted as an end-point event.

Inclusion and exclusion criteria

Inclusion Criteria:

previously untreated histologically proven epithelial ovarian cancer, tubal or peritoneal primary carcinoma, of FIGO stage IV or extensive stage III deem not feasible for primary cytoreductive surgery
histologic epithelial cell types as follows: Serous adenocarcinoma, endometrioid adenocarcinoma, mucinous adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, transitional cell carcinoma, malignant Brenner's Tumor, or adenocarcinoma not otherwise specified (N.O.S.).
well informed about the rationale of neoadjuvant chemotherapy as an alternative to upfront surgery followed by adjuvant chemotherapy and accepted treatment with three to four cycles of neoadjuvant treatment with three to four cycles of platinum-based regimen without progression followed by interval cytoreductive surgery
performance status of ECOG 0-2
adequate hematopoietic function is defined as below:
- ANC ≥ 1,500/uL, equivalent to Common Toxicity Criteria for Adverse Events v4.03 (CTCAE) Grade1.
- Platelets ≥ 100,000/uL (CTCAE Grade 0-1).
- INR is ≦ 1.5 (or an in-range INR, usually between 2 and 3, if a patient is on a stable dose of therapeutic warfarin) and aPTT < 1.2 x ULN
adequate organ function is defined as below:
- total bilirubin ≦ 1.5 × ULN (CTCAE Grade 1).
- ALT/AST≦2.5 x ULN and alkaline phosphatase≦2.5 x ULN (CTCAE Grade 1)
- serum creatinine ≦ 1.5 × ULN (CTCAE Grade 1).
adequate neurologic function, neuropathy (sensory and motor) ≦ CTCAE Grade 1
age 20-75 years old
Patients must have measurable and non-measurable disease. Patients may or may not have cancer-related symptoms.
life expectancy equal or longer than 3 months
Patients who have met the pre-entry requirements
ability to understand and willingness to sign a written informed consent document (within 3 weeks after interval surgery)

Exclusion Criteria

borderline ovarian tumors, recurrent epithelial ovarian, tubal or peritoneal or non-epithelial cancers
history or evidence upon physical examination of CNS disease, including primary brain tumor, seizures not controlled with standard medical therapy, any brain metastases, or history of cerebrovascular accident (CVA, stroke), transient ischemic attack (TIA) or subarrachnoid hemorrhage within six months of the first date of treatment on this study.
Patients with synchronous primary endometrial cancer, or a past history of primary endometrial cancer, are excluded.
other malignancy with exception of curative treated non-melanoma skin cancer or cervical carcinoma in situ within 5 years prior to entering the study
patients who have received any targeted therapy (including but not limited to vaccines, antibodies, tyrosine kinase inhibitors) or hormonal therapy for management of their ovarian, peritoneal primary or fallopian tube carcinoma
patients with serious, non-healing wound, ulcer, or bone fracture.
patients with granulating incisions healing by secondary intention with no evidence of fascial dehiscence or infection are eligible but require weekly wound examinations.
history of abdominal fistula, gastrointestinal perforation, intra-abdominal abscess or active gastrointestinal bleeding within 6 months.
patients with active bleeding or pathologic conditions that carry high risk of bleeding, such as known bleeding disorder, coagulopathy, or tumor involving major vessels
clinically significant proteinuria. Urine protein should be screened by urine protein-creatinine ratio (UPCR). The UPCR has been found to correlate directly with the amount of protein excreted in a 24 hour urine collection. Specifically, a UPCR of 1.0 is equivalent to 1.0 gram of protein in a 24 hour urine collection. Obtain at least 4 ml of a random urine sample in a sterile container (does not have to be a 24 hour urine). Send sample to lab with request for urine protein and creatinine levels [separate requests]. The lab will measure protein concentration (mg/dL) and creatinine concentration (mg/dL) The UPCR is derived as follows: protein concentration (mg/dL)/creatinine (mg/dL). Patients must have a UPCR < 1.0 to allow participation in the study.
clinical significant cardiovascular disease
- Uncontrolled hypertension, defined as systolic >150 mm Hg or diastolic> 90 mm Hg.
- Prior history of hypertensive crisis or hypertensive encephalopathy
- active cardiac disease e.g. decompensated myocardial infarction within the 6-month period preceding entry into the study.
- New York Heart Association (NYHA) Grade II or greater congestive heart failure
- serious cardiac arrhythmia requiring medication.
- CTCAE Grade 2 or greater peripheral vascular disease (at least brief (24 hrs) episodes of ischemia managed non-surgically and without permanent deficit)
- History of CVA within six months.
known hypersensitivity to Chinese hamster ovary cell products or other recombinant human or humanized antibodies
presence of other serious concomitant illness which can affect or elevate the value of CA-125, e.g.;
- Autoimmune disease
- Sarcoidosis
- Chronic active hepatitis
- Pericarditis
- Cirrhosis of liver
- Abdominal tuberculosis
- Pancreatitis
acute hepatitis or active infection that requires parenteral antibiotics
anticipation of invasive procedures as defined below:

- Major surgical procedure anticipated during the course of the study.
- Core biopsy within 7 days prior to the first date of Bevacizumab therapy (cycle 2).
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 three years prior to registration, and the patient remains free of recurrent or metastatic disease.

mental status is not fit for clinical trial
Patients who are pregnant or nursing. Subjects of child-bearing age have to use effective means of contraception
