Clinical Trial Summary

This phase I/II trial studies the side effects and best dose of lenalidomide and to see how well it works in treating patients with acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma (KS). Lenalidomide may stop the growth of tumor cells by blocking blood flow to the tumor.

Description:

PRIMARY OBJECTIVES: I. Determine the maximum tolerated dose (MTD) of single agent lenalidomide in subjects with AIDS-related KS. (Phase I) II. Evaluate the overall clinical response of KS tumors to lenalidomide with subset assessments of partial response (PR) and complete response (CR). (Phase II) SECONDARY OBJECTIVES: I. Evaluate the effect of lenalidomide on human immunodeficiency virus (HIV) plasma viral loads. II. Determine the effects of lenalidomide on T-lymphocyte subsets, including natural killer (NK) cells. III. Evaluation of time to response, time to relapse, and time to death amongst subjects receiving lenalidomide. IV. Determine the effect of lenalidomide on human herpesvirus (HHV)-8. V. Assess lenalidomide effects on HHV-8 copy number in peripheral blood mononuclear cell (PBMC), and plasma and whether changes in viral copy number measured in PBMC or plasma are associated with clinical response of KS tumors. VI. Monitor HHV-8 gene expression in KS biopsy specimens and PBMC pre- and post-lenalidomide and assess whether changes in viral gene expression in tumor biopsy are associated with clinical response. VII. Assess whether changes in viral copy number in the compartments assayed occur in concert or independently with changes in viral antigen expression in biopsy specimens. VIII. Assess effects of lenalidomide on growth factors relevant to tumor proliferation (i.e., interleukin [IL]-1beta, IL-2, IL-4, IL-5, IL-6, IL-10, IL-15, IL-12p70, tumour necrosis factor [TNF]alpha, and interferon gamma [IFN]gamma). IX. Characterize the effects of lenalidomide on viral and cellular gene in KS tumor biopsies. X. Assess changes in NK cell number (PBMC and tumor) and function pre- and post-lenalidomide. XI. Assess the sensitivity and specificity of dermal adhesive strip samples to detect KS and the effects of lenalidomide on the lesions. OUTLINE: This is a multicenter study. This is a phase I, dose-escalation study of lenalidomide followed by a phase II study. Patients receive lenalidomide orally (PO) once daily on days 1-21. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days.

• There should be no evidence for improvement in KS in the 3 months prior to study entry, unless there is evidence for progression of KS in the 4 weeks immediately prior to study entry
• If antiretroviral regimen contains zidovudine and viral load is suppressed (as measured by HIV viral load =< 200/mL), then antiretroviral therapy must be adjusted to a less toxic therapy not containing zidovudine and enrollment may proceed without waiting 12 weeks; if on zidovudine-containing therapy and viral load is not suppressed (as measured by HIV viral load >= 200/mL), then antiretroviral therapy must be adjusted to a less toxic regimen allowing for optimal viral suppression and must demonstrate stability for at least 12 weeks prior to study entry
• Patients with any history of pulmonary embolism (PE) or deep venous thrombosis (DVT) or predisposing clotting risk factors must be on anticoagulation at therapeutic dosing

• Concurrent, acute, active opportunistic infection other than oral thrush or genital herpes within 14 days of enrollment

• Concurrent neoplasia requiring cytotoxic therapy
• Acute treatment for an infection (other than oral thrush or genital herpes) or other serious medical illness within 14 days of study entry

following:

• Basal cell skin cancer
• Cervical carcinoma in situ
• Anal carcinoma in situ

• Use of any investigational drug or treatment within 4 weeks prior to enrollment
• Physical or psychiatric conditions that in the estimation of the investigator place the patient at high risk of toxicity or non-compliance
• Female patients who are pregnant or breast-feeding
• Patients with a history of DVT or PE within 1 year
