I. To determine whether the addition of bevacizumab to fixed-dose rate gemcitabine-docetaxel reduces the progression-free survival (PFS) event rate when compared to gemcitabine-docetaxel plus placebo in patients with advanced or recurrent uterine leiomyosarcoma (LMS).
I. To determine the objective response rate, as measured by RECIST, of patients treated with fixed-dose rate gemcitabine-docetaxel with bevacizumab, compared with the objective response rate of patients treated with fixed-dose rate gemcitabine-docetaxel with placebo.
II. To determine if the addition of bevacizumab to the combination of gemcitabine and docetaxel increases overall survival in patients with advanced or recurrent uterine LMS.
III. To determine the toxicity profile of fixed-dose rate gemcitabine-docetaxel with and without bevacizumab in this patient population.
IV. To bank formalin-fixed and paraffin-embedded (FFPE) tumor tissue for research.
OUTLINE: This is a multicenter study. Patients are stratified according to prior whole-pelvic radiotherapy (yes vs no). Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive a placebo IV over 30-90 minutes on day 1, gemcitabine hydrochloride IV over 90 minutes on days 1 and 8, and docetaxel IV over 60 minutes on day 8. Patients also receive filgrastim subcutaneously (SC) on days 9-15 or pegfilgrastim SC on day 9 or 10.
ARM II: Patients receive bevacizumab IV over 30-90 minutes on day 1, gemcitabine hydrochloride IV over 90 minutes on days 1 and 8, and docetaxel IV over 60 minutes on day 8. Patients also receive filgrastim SC on days 9-15 or pegfilgrastim SC on day 9 or 10.
In both arms, courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
- Patients must have advanced or recurrent uterine leiomyosarcoma with documented disease progression; histologic confirmation of the original primary tumor is required
- All patients must have measurable disease as defined by RECIST 1.1; measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded); each lesion must be >= 10 mm when measured by CT, MRI or caliper measurement by clinical exam; or >= 20 mm when measured by chest x-ray; lymph nodes must be >= 15 mm in short axis when measured by CT or MRI
- Patient must have at least one "target lesion" to be used to assess response on this protocol as defined by RECIST 1.1; tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy

- Bilirubin within normal range (CTCAE Version 4 Grade 0)
- SGOT and alkaline phosphatase less than or equal to 2.5 x ULN, per the CTCAE Version 4.0 Grade 1)
- SGOT less than or equal to 2.5 x ULN, per the CTCAE Version 4.0 Grade 1
- Alkaline phosphatase less than or equal to 2.5 x ULN, per the CTCAE Version 4.0 Grade 1

- No history of transient ischemic attack (TIA) or stroke or CNS hemorrhage within the past 6 months
- Urine protein creatinine (UPC) ratio must be < 1.0 gm; if UPC ratio >= 1, collection of 24-hour urine measurement of urine protein is recommended
- PT such that international normalized ratio (INR) is =< 1.5 and a PTT =< 1.5 times the institutional upper limit of normal (or an in-therapeutic-range INR, usually between 2 and 3, if a patient is on a stable dose of therapeutic warfarin)
- Patients must have signed an approved informed consent and authorization permitting release of personal health information
- Patients must meet pre-entry requirements
- Patients of childbearing potential must have a negative serum pregnancy test prior to the study entry and be practicing an effective form of contraception
- Patients who have received prior cytotoxic chemotherapy for management of uterine sarcoma; patients who have received prior VEGF-pathway targeted agent such as bevacizumab, PTK787, VEGF-trap, or who have received prior treatment with a multi-kinase inhibitor such as sorafenib or sunitinib are not eligible
- Patients who have had prior therapy with docetaxel or gemcitabine or bevacizumab
- Patients with a history of other invasive malignancies, with the exceptions of non-melanoma skin cancer, carcinoma in situ of the cervix, and ductal carcinoma in situ of the breast, are excluded if there is any evidence of other malignancy being present within the last five years; patients are also excluded if their previous cancer treatment contraindicates this protocol therapy
- Patients with active bleeding or pathologic conditions that carry high risk of bleeding, such as known bleeding disorder, coagulopathy, or tumor involving major vessels; (necessary use of warfarin or low molecular weight heparin is permitted, provided the INR is maintained in the therapeutic range of approximately 2-3)
