Lenalidomide for Adult Histiocyte Disorders

Korábbi kezelés

• Prior chemotherapy or radiation within 2 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 2 weeks earlier.
• Participants who are receiving any other investigational agents.
• Prior treatment with lenalidomide. Patients previously treated with thalidomide who discontinued treatment for reasons aside from an adverse reaction to thalidomide are permitted.
• Pregnant women are excluded from this study because lenalidomide has known teratogenic effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with lenalidomide, breastfeeding should be discontinued if the mother is treated with lenalidomide.
• Known active hepatitis B (HBV) or hepatitis C (HCV) infection. Patients who are positive only for HBV surface antibody as a result of prior vaccination are eligible. Patients with a positive HBV core antibody but undetectable HBV viral load are eligible.
• HIV-positive participants on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with lenalidomide. In addition, these participants are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in participants receiving combination antiretroviral therapy when indicated.
• Concomitant corticosteroids unless patient has been on a stable dose of prednisone (or equivalent) of ≤10 mg daily for at least 2 weeks prior to first dose of study drug.

Más betegség

• History of another invasive malignancy unless treated with curative intent 5 years or more prior to study entry. Patients with localized carcinoma of the cervix, non-melanoma skin cancer, or early stage prostate cancer requiring observation only are eligible regardless of timing of diagnosis.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

• Able to take aspirin 81 mg daily as prophylactic anticoagulation if not on warfarin, low molecular weight heparin or oral factor Xa inhibitor. Patients intolerant to ASA may use warfarin or low molecular weight heparin at doses designed to treat deep venous thrombosis.
