Trial Information

A Phase II Evaluation of Ixabepilone (BMS-247550) [NCI-Supplied Agent, IND #59699, NSC #710428]) in the Treatment of Recurrent or Persistent Endometrial Carcinoma


I. Determine the response rate in patients with recurrent or persistent endometrial
adenocarcinoma treated with ixabepilone.

II. Determine the nature and degree of toxicity of this drug in these patients.

OUTLINE: This is a multicenter study.

Patients receive ixabepilone IV over 3 hours on day 1. Courses repeat every 21 days in the
absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years and then every 6 months for 3 years.

PROJECTED ACCRUAL: A total of 19-51 patients will be accrued for this study within 2.5

Inclusion Criteria:

- Histologically confirmed endometrial adenocarcinoma

- Recurrent or persistent disease

- Histologic confirmation of the original primary tumor is required

- Not amenable to management with any of the following:

- Surgery

- Radiotherapy

- Higher priority or standard chemotherapy

- Measurable disease

- At least 1 unidimensionally measurable lesion ≥ 20 mm by conventional techniques
(e.g., palpation, plain x-ray, CT scan, or MRI) OR ≥ 10 mm by spiral CT scan

- At least 1 target lesion

- Tumors within a previously irradiated field are designated as non-target

- Disease in an irradiated field as the only site of measurable disease is
acceptable as a target lesion only if there has been clear progression of the
lesion at least 90 days after completion of radiotherapy

- Received 1, and only 1, prior chemotherapy regimen (e.g., high-dose therapy,
consolidation, or extended therapy administered after surgery or non-surgical
assessment) for management of endometrial adenocarcinoma

- Ineligible for a higher priority Gynecologic Oncology Group (GOG) protocol (e.g., any
active GOG phase III study for the same patient population)

- Performance status - GOG 0-2

- Absolute neutrophil count ≥ 1,500/mm^3

- Platelet count ≥ 100,000/mm^3

- Bilirubin ≤ 1.5 times upper limit of normal (ULN)

- AST ≤ 2.5 times ULN

- Alkaline phosphatase ≤ 2.5 times ULN

- Creatinine ≤ 1.5 times ULN

- Sensory or motor neuropathy ≤ grade 1

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception

- No active infection requiring antibiotics

- No other invasive malignancies within the past 5 years except non-melanoma skin

- At least 3 weeks since prior biologic or immunologic agents directed at the malignant

- One prior non-cytotoxic* (biologic or cytostatic) regimen for management of recurrent
or persistent disease allowed

- See Disease Characteristics

- Prior paclitaxel or docetaxel allowed

- Recovered from prior chemotherapy

- No more than 1 prior cytotoxic chemotherapy regimen (either single or combination
drug therapy)

- No prior ixabepilone

- At least 1 week since prior hormonal therapy directed at the malignant tumor

- Continuation of hormone replacement therapy allowed

- See Disease Characteristics

- Recovered from prior radiotherapy

- Recovered from prior surgery

- At least 3 weeks since other prior therapy directed at the malignant tumor

- No prior cancer treatment that contraindicates study therapy
