SB-715992 in Treating Patients With Metastatic or Recurrent Malignant Melanoma

RATIONALE: Drugs used in chemotherapy, such as SB-715992, work in different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: This phase II trial is studying how well SB-715992 works in treating patients with metastatic or recurrent malignant melanoma.

OBJECTIVES:

* Determine the efficacy of SB-715992, in terms of response rate, in patients with previously untreated metastatic or recurrent malignant melanoma.
* Determine the toxic effects of this drug in these patients.
* Determine the early progression rate and response duration in patients treated with this drug.
* Determine the pharmacokinetics of this drug in these patients.
* Correlate pharmacokinetics with safety and efficacy endpoints of this drug in these patients.
* Correlate β-tubulin and kinesin spindle protein expression in tumor tissue with clinical outcomes in patients treated with this drug.

OUTLINE: This is a nonrandomized, multicenter study.

Patients receive SB-715992 IV over 1 hour on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

All patients are followed at 4 weeks after completion of protocol therapy. Patients with ongoing complete response, partial response, or stable disease are followed every 3 months thereafter until relapse.

PROJECTED ACCRUAL: A total of 15-25 patients will be accrued for this study within 12-14 months.

Eligibility Criteria:
DISEASE CHARACTERISTICS:

* Histologically confirmed malignant melanoma

  * Previously untreated metastatic or recurrent disease

* No known CNS metastases

  * CT scans or MRI are not required to rule out CNS metastases unless patient exhibits neurological signs or symptoms
  * Patients with a prior solitary brain metastasis surgically resected with no evidence of residual disease are eligible provided CT scan or MRI confirms no evidence of disease within the past 28 days
