Trial Information

A Phase II Trial of BMS 247550 (Ixabepilone) in Advanced Renal Cell Carcinoma


I. Determine the objective response rate in patients with metastatic, recurrent, or
unresectable renal cell carcinoma treated with ixabepilone.


I. Determine the progression-free and overall survival rates in patients treated with this

II. Determine the toxicity of this drug in these patients. III. Correlate VHL gene mutations
with response in patients treated with this drug.

IV. Correlate VHL pathway protein expression with response in patients treated with this

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.

After completion of study therapy, patients are followed every 9 weeks until disease
progression and then every 3 months for up to 2 years.

Inclusion Criteria:

- Histologically or cytologically confirmed renal cell carcinoma of 1 of the
following subtypes:

- Clear cell

- Papillary, type I or II

- Chromophobe

- Collecting duct

- Medullary

- Metastatic, recurrent, or unresectable disease

- Measurable disease, defined as ≥ 1 unidimensionally measurable lesion ≥ 20 mm by
conventional techniques OR ≥ 10 mm by spiral CT scan

- No known active brain metastases requiring steroid or anticonvulsant therapy

- Patients with definitively treated brain metastases are eligible provided they
are not on steroids or anticonvulsants AND show no evidence of disease
progression for ≥ 3 months after completion of definitive therapy

- Performance status - ECOG 0-2

- At least 3 months

- WBC ≥ 3,000/mm^3

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

- Platelet count ≥ 100,000/mm^3

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

- AST and ALT ≤ 2.5 times ULN

- Creatinine ≤ 1.5 times ULN

- Glomerular filtration rate ≥ 50 mL/min

- No symptomatic congestive heart failure

- No unstable angina pectoris

- No cardiac arrhythmia

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception

- No ongoing or active infection

- No HIV positivity

- No peripheral neuropathy > grade 1

- No psychiatric illness or social situation that would preclude study compliance

- No history of allergic reaction attributed to compounds of similar chemical or
biological composition to study drug

- No history of severe hypersensitivity reaction to agents containing Cremophor® EL

- No other active malignancy

- Curatively treated malignancies are allowed provided the risk of recurrent
disease at the time of study enrollment is < 20%

- No other uncontrolled illness

- More than 4 weeks since prior chemotherapy (6 weeks for nitrosoureas or mitomycin)
and recovered

- No prior tubule inhibitors, including, but not limited to, any of the following:

- Vinca alkaloids (e.g., vinblastine, vincristine, or vinorelbine)

- Taxanes (e.g., docetaxel or paclitaxel)

- Epothilones

- No other concurrent chemotherapy

- See Disease Characteristics

- No concurrent hormonal therapy except steroids for adrenal failure or
hypersensitivity prophylaxis or hormones for non-disease related conditions (e.g.,
insulin for diabetes)

- More than 4 weeks since prior radiotherapy and recovered

- No concurrent palliative radiotherapy

- No other concurrent investigational agents

- No other concurrent anticancer therapy
