In addition, patients must not receive live, attenuated vaccines (e.g., FluMist®) while receiving study treatment or after the last dose until B-cell recovery to the normal ranges. Inactivated influenza vaccination is permitted during influenza season.\n* Patients with any one of the following currently or in the previous 6 months will be excluded: myocardial infarction, congenital long QT syndrome, torsade de pointes, unstable angina, or coronary\u002Fperipheral artery bypass graft.\n* Patients with New York Heart Association Class III or IV heart failure or with Objective Assessment Class C or D cardiac disease.\n* For patients receiving pirtobrutinib:\n\n  * Significant cardiovascular disease defined as:\n\n    * unstable angina or acute coronary syndrome within the past 2 months prior to randomization\n    * history of myocardial infarction within 3 months prior to randomization or\n    * documented LVEF by any method of ≤ 40% in the 12 months prior to randomization\n  * Uncontrolled or symptomatic arrhythmias\n\n    * Note: patients with atrial fibrillation are allowed as long as they are adequately rate-controlled.)\n    * Note: Patients with pacemakers are eligible if they have no history of fainting or clinically relevant arrhythmias while using the pacemaker\n  * Prolongation of the QT interval corrected for heart rate (QTcF) \\> 470 msec. QTcF is calculated using Fridericia's Formula (QTcF): QTcF = QT\u002F(RR0.33).\n\n    * Correction of suspected drug-induced QTcF prolongation can be attempted at the investigator's discretion and only if clinically safe to do so with either discontinuation of the offending drug or switch to another drug not known to be associated with QTcF prolongation.\n    * Correction for underlying bundle branch block (BBB) allowed.\n  * Clinically significant active malabsorption syndrome or other condition likely to affect gastrointestinal (GI) absorption of the study drug.\n  * Active uncontrolled auto-immune cytopenia (e.g., autoimmune hemolytic anemia \\[AIHA\\], idiopathic thrombocytopenic purpura \\[ITP\\]) for which new therapy was introduced or existing therapy was escalated within the 4 weeks prior to study enrollment to maintain adequate blood counts.\n  * Patients requiring therapeutic anticoagulation with warfarin or another vitamin K antagonist.\n  * Have a known hypersensitivity to any of the excipients of Pirtobrutinib or to any intended study medications.\n  * Patients who experienced a major bleeding event or grade ≥ 3 arrhythmia on prior treatment with a BTK inhibitor. Note: Major bleeding is defined as bleeding having one or more of the following features: potentially life-threatening bleeding with signs or symptoms of hemodynamic compromise; bleeding associated with a decrease in the hemoglobin level of at least 2g per deciliter; or bleeding in a critical area or organ (e.g., retroperitoneal, intraarticular, pericardial, epidural, or intracranial bleeding or intramuscular bleeding with compartment syndrome)\n  * History of bleeding disorders (e.g. von Willebrand's disease, hemophilia).\n  * History of stroke or intracranial hemorrhage within 6 months of starting study therapy.\n* Inability to comply with protocol mandated hospitalizations and restrictions.\n* Patients who are pregnant, breast-feeding, or intending to become pregnant during the study.\n* Any other diseases, metabolic dysfunction, physical examination finding, mental status or clinical laboratory finding giving reasonable suspicion of a disease or condition that would contraindicate the use of an investigational drug.",{"count":113,"type":20},70,[53],"This research is being done to evaluate Glofitamab by itself or in combination with Polatuzumab Vedotin, Pirtobrutinib, or Atezolizumab as possible treatments for Chronic Lymphocytic Leukemia (CLL) that has transformed into Richter's Transformation (RT).\n\nThe names of the study drugs involved in this research study are:\n\n* Glofitamab (a T-cell bispecific humanized monoclonal antibody)\n* Obinutuzumab (a humanized glycoengineered type II anti-CD20 monoclonal antibody)\n* Polatuzumab vedotin (an antibody-drug conjugate)\n* Pirtobrutinib (a selective inhibitor of BTK)\n* Atezolizumab (a humanized immunoglobulin monoclonal antibody)\n* Tocilizumab (a recombinant, humanized, anti-human monoclonal antibody)",[117,27],"Chronic Lymphocytic Leukemia",[117,119,27],"CLL","2026-01-05",{"date":122,"type":34},"2026-01-07",{"date":124,"type":34},"2024-01-22",{"date":126,"type":20},"2033-01-15",{"name":128,"class":41},"Christine Ryan",{"id":130,"slug":131,"hasResults":11,"nctId":132,"briefTitle":133,"officialTitle":134,"acronym":135,"eligibilityCriteria":136,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":137,"targetDuration":139,"studyType":140,"phases":4,"briefSummary":141,"conditions":142,"keywords":150,"overallStatus":30,"whyStopped":4,"lastUpdateSubmitDate":154,"lastUpdatePostDateStruct":155,"startDateStruct":157,"completionDateStruct":159,"leadSponsor":161,"locationsCount":42},"100275317","registry-of-the-german-cll-study-group-100275317","NCT02863692","Registry of the German CLL Study Group","Registry of the German CLL Study Group Long Term Follow-up of Patients With CLL, B-PLL, T-PLL, SLL,T or NK-LGL, HCL and Richter's Transformation","CLL-Registry","Inclusion Criteria (all must apply)\n\n1.
