This study looks at a vaccine made from a patient's own tumor cells that produce CD40 ligand and IL-2, used to treat B-cell chronic lymphocytic leukemia (B-CLL). Patients with B-CLL who had measurable disease were able to take part. Sponsored by Baylor College of Medicine, the study was conducted in Phase 1 and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
INCLUSION CRITERIA: Eligibility for blast collection: * Patients are eligible for administration of their vaccine if they present with B-CLL (not in Richter's transformation) with measurable disease. * Procurement consent signed and faxed to Research Coordinator * Eligibility for Vaccine Administration (protocol entry) * Manipulated B-CLL cells available (at least 12 injections) * Patients are eligible for administration of their vaccine if they present with B-CLL (not in Richter's transformation) with measurable disease * Patients must have a life expectancy of at least 10 weeks. * Patients must have ECOG performance status of 0-2 as below: * Grade 0: Up and about, no restriction * Grade 1: Ambulatory, no strenuous activity * Grade 2: Ambulatory, capable of self-care appropriate for age.

Patients will be given a copy of the consent form. * Patient must not have received treatment with other investigational agents within the last 4 weeks. EXCLUSION CRITERIA: * Infected at time of protocol entry, or receiving antibiotics (other than prophylactic trimethoprim sulfamethoxazole). * HIV positive * Pregnant or lactating * Suffering from an autoimmune disease (including active graft-versus-host disease-GvHD, refractory immune thrombocytopenia-ITP or refractory autoimmune hemolytic anemia-AIHA) * Receiving immunosuppressive drugs * Patients without adequate cardiac function (congestive heart failure, significant arrhythmia)
