Clinical Trial Summary

In this research study we will start by looking for the highest dose of pyrimethamine that can be given safely to CLL patients without severe or unmanageable side effects. This dose will then be used for a larger Phase II study to assess the efficacy of pyrimethamine for the treatment of CLL/SLL. Pyrimethamine is an antibiotic that is used for the treatment of certain infections. Previous research studies have shown that pyrimethamine may target a protein in tumor cells, called STAT3, which may be important for the growth of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) cells. Pyrimethamine can kill CLL/SLL cells in the laboratory, and we are therefore undertaking this study to assess whether pyrimethamine will result in clinical benefit or tumor responses in CLL in patients.


Clinical Trial Description

- Participants will be required to enroll in DFCI Protocol 99-224, the CLL Research Consortium Tissue Bank, and DFCI Protocol 01-206, Tissue and Data Collection for Research Studies in Patients with Hematologic Malignancies, Bone Marrow Disorders, and Normal Donors, or may have blood banked for future use. - Each treatment cycle lasts 28 days during which time participants will take pyrimethamine orally once per day. Since we are looking for the highest dose of the study drug that can be administered safely without severe or unmanageable side effects, not everyone who participates will receive the same dose of study drug. - The following tests and procedures will be performed at specific time points during participation in the study: Physical exam, vital signs, blood tests and bone marrow biopsy. The participant's tumor will be assessed by CT scans of the chest, abdomen and pelvis prior to the start of the study and at the end of the 1st, 3rd and 6th months. - Participants can continue to receive pyrimethamine as long as they do not have side effects and their disease does not worsen. ;
