Brief Summary:

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for their growth.

PURPOSE: This phase II trial is studying how well imatinib mesylate works in treating patients with HIV-related Kaposi's sarcoma.

Condition or disease Intervention/treatment Phase
Sarcoma Drug: imatinib mesylate Phase 2

Detailed Description:



  • Determine clinical response in patients with HIV-related Kaposi's sarcoma treated with imatinib mesylate.


  • Determine the inhibition of platelet-derived growth factor receptors, as determined by immunohistochemistry, in patients treated with this drug.
  • Determine cytokine profiles before and after treatment with this drug in these patients.
  • Determine the pharmacokinetic profile of this drug and antiretrovirals in these patients.
  • Determine mechanisms of primary and secondary resistance to this drug in these patients.

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

Patients receive oral imatinib mesylate once daily. Treatment continues for up to 1 year in the absence of disease progression or unacceptable toxicity.

Patients are followed at 30 days.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 1 year.

Primary Purpose: Treatment
Official Title: A Phase II Trial Of Imatinib Mesylate (Gleevec) In Patients With HIV Related Kaposi's Sarcoma
Study Start Date : June 2005
Actual Primary Completion Date : December 2009
Actual Study Completion Date : December 2009

Arm Intervention/treatment
Experimental: Imatinib mesylate
Imatinib mesylate (Gleevec) taken 400 mg orally once a day for up to 6 months
Drug: imatinib mesylate
400 mg orally once a day for up to 6 months.
Other Name: Gleevec

Primary Outcome Measures :
  1. Proportion of Patients Who Achieve a Clinical Response [ Time Frame: 20-24 weeks ]
    Clinical response = Complete Response (absence of residual disease) or Partial Response defined as no new lesions (skin or oral), or no new visceral sites of involvement (or the appearance or worsening of tumor-associated edema or effusions); AND 50% or greater decrease in the number of lesions lasting for >4 weeks; OR Complete flattening of at least 50% of all previously raised lesions OR A 50% decrease in the sum of the products of the largest perpendicular diameters of the marker lesions

Secondary Outcome Measures :
  1. Inhibition of Platelet-derived Growth Factor-receptor as Assessed by Immunohistochemistry [ Time Frame: 12 months ]
  2. Cytokine Profiles Before and After Imatinib Therapy [ Time Frame: 12 months ]
  3. Pharmacokinetic Profile of Imatinib and Antiretrovirals [ Time Frame: 12 months ]
  4. Mechanisms of Primary and Secondary Resistance to Imatinib Therapy [ Time Frame: 12 months ]
    Mutations in the juxtamembrane or kinase membrane of the c-kit or PDGF receptors at baseline or time of progression

  5. Viral Transcription Profile of Kaposi's Sarcoma-associated Herpesvirus [ Time Frame: 12 months ]
