Title
Dose-escalating Trial With UniCAR02-T Cells and CD123 Target Module (TM123) in Patients With Hematologic and Lymphatic Malignancies
Multicenter, Open-label, Adaptive Design Phase I Trial With Genetically Modified T-cells Carrying Universal Chimeric Antigen Receptors (UniCAR02-T) in Combination With CD123 Target Module (TM123) for the Treatment of Patients With Hematologic and Lymphatic Malignancies Positive for CD123

90This dose-escalating phase I trial assesses for the first time the safety, the side effects and the harmlessness, as well as the therapeutical benefit of the new study drug UniCAR02-T-CD123 in patients with hematologic and lymphatic malignancies positive for CD123 marker. The UniCAR02-T-CD123 drug is a combination of a cellular component (UniCAR02-T) with a recombinant antibody derivative (TM123) which together forms the active drug.

Inclusion Criteria: Male or female patients, age ≥ 18 years Documented definitive diagnosis of AML or BPDCN (according to standard of care testing) and CD123 positivity of ≥20 % of blasts. In the case of MRD+ AML, if there are insufficient blasts at screening for CD123 testing, the most recent available sample with sufficient blasts should be used. - Relapsed or refractory AML/BPDCN Eastern Cooperative Oncology Group (ECOG) of 0 to 1 Life expectancy of at least 2 months Adequate renal and hepatic laboratory assessments Adequate cardiac function Permanent venous access existing (e.g. port-system) resp. acceptance of implantation of a device Able to give written informed consent Weight ≥ 45 kg Negative pregnancy; routinely using a highly effective method of birth control Exclusion Criteria: Acute promyelocytic leukemia (t15;17) Refractory disease under anti-leukemic treatment lasting longer than 6 months Manifestation of AML or BPDCN in central nervous system Bone marrow failure syndromes Cardiac disease: i.e. heart failure (NYHA III or IV); unstable coronary artery disease, myocardial infarction or serious cardiac ventricular arrhythmias requiring anti-arrhythmic therapy within the last 6 months prior to study entry Patients undergoing renal dialysis Pulmonary disease with clinical relevant hypoxia Parkinson, epilepsy and, stroke or presence or history of seizures, paresis, aphasia or intracranial hemorrhage Presence of disseminated intravascular coagulation (DIC) or thromboembolism, or history of such within 3 months prior to start of treatment Hemolytic anemia Multiple sclerosis Active infectious disease considered by investigator to be incompatible with protocol or being contraindications for lymphodepletion therapy Presence of urotoxicity from previous chemo- or radiotherapy or urinary outflow obstruction Allogeneic stem cell transplantation within last two months or Graft versus host disease (GvHD) requiring immunosuppressive therapy Vaccination with live viruses less than 2 weeks prior lymphodepletion therapy Major surgery within 28 days Other malignancy requiring active therapy but adjuvant endocrine therapy is allowed Treatment with any investigational drug substance or experimental therapy within 4 weeks or 5 half-lives (whatever is shorter) of the substance prior to the day of apheresis Prior treatment with gene therapy products Use of checkpoint inhibitors within 5 half-lives of the respective substance Autoimmune diseases requiring systemic steroids or other systemic immunosuppressants Pregnant or breastfeeding women Psychologic disorders, drug and/or significant active alcohol abuse Known history of human immunodeficiency virus (HIV) or active/chronic infection with hepatitis C virus (HCV) or hepatitis B virus (HBV) Presence of autoantibodies against La/Sjögren syndrome (SS)-B or presence or history of autoimmune diseases Known hypersensitivity to cellular component (UniCAR02-T) and/or targeting module (TM123) excipients or to compounds of the lymphodepletion therapy or tocilizumab or corticosteroids Evidence suggesting that the patient is not likely to follow the study protocol Incapability of understanding purpose and possible consequences of the trial Patients who should not be included according to the opinion of the investigator
