This phase II trial is studying how well oblimersen works in treating patients with Merkel cell cancer. Biological therapies, such as oblimersen, may interfere with the growth of tumor cells and slow the growth of Merkel cell carcinoma (skin cancer).

Primary Outcome Measures:
  • Overall response rate [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to progression [ Time Frame: Interval between the start of treatment and until the criteria for progression are met, assessed up to 3 years ] [ Designated as safety issue: No ]
    Progression-free survival probabilities will be computed using Kaplan-Meier methods.

  • Occurrence of adverse events, assessed using revised NCI CTC version 3.0 [ Time Frame: Within 30 days of treatment ] [ Designated as safety issue: Yes ]

Enrollment: 37

Primary Completion Date: January 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (oblimersen sodium)
Patients receive oblimersen IV continuously on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Detailed Description:


I. Determine the overall response rate in patients with Merkel cell carcinoma treated with oblimersen.


I. Determine the time to progression in patients treated with this drug. II. Determine the response duration in patients treated with this drug. III. Determine the safety and tolerability of this drug in these patients. IV. Determine the pharmacodynamic effects of this drug on bcl-2 expression and apoptosis in tumor biopsy specimens from these patients.

OUTLINE: This is an open-label, multicenter study.

Patients receive oblimersen IV continuously on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
