This study investigated the safe dose of the PRGN-3007 UltraCAR-T cell therapy in patients with advanced blood cancers and solid tumors, using Fludarabine and Cyclophosphamide chemotherapy as preparation. It enrolled patients aged 18 and older with adequate organ function. It 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.
Key Inclusion Criteria: * Age 18 years and older * Eastern Cooperative Oncology Group (ECOG) score of 0 or 1; or Karnofsky Performance Status (KPS) of ≥ 70%. * Life expectancy ≥ 12 weeks from the time of enrollment * Must have adequate organ function, as defined in protocol. * Patients must be at least 2 weeks or 5 half-lives (whichever is shorter)post systemic steroids prior to enrollment except as premedication for contrast allergy * Negative serum pregnancy test for women of child bearing potential (WOCBP). Fertile male and female patients must be willing to use a contraceptive method before, during, and for at least 12 months after the last T cell infusion * All patients must have the ability to understand and willingness to sign a written informed consent form (ICF). Exclusion Criteria: * Patient has received any of the following treatments prior to leukapheresis: cytotoxic chemotherapy or radiation therapy within 14 days; an antineoplastic monoclonal antibody within prior 4 weeks; prior targeted therapy 14 days or 5 half-lives from the last dose whichever is shorter; or prior systemic inhibitory/stimulatory immune checkpoint molecule therapy (eg, ipilimumab, nivolumab, pembrolizumab, atezolizumab, OX40 agonists, 4-1BB agonists) within 3 half-lives; or has not recovered from (i.e., ≤ grade 1) adverse event (AE) caused by prior treatment. Exceptions include hydroxyurea, single agent vincristine or steroids for uncontrolled ALL. * Burkitt lymphoma is excluded. * Prior allogeneic hematopoietic stem cell transplant (HSCT) or donor lymphocyte infusion within 6 months prior to enrollment, current acute graft versus host disease grade 2-4 by Glucksberg criteria or severity B-D by by International Bone Marrow Transplant Registry (IBMTR) index or history of severe (grade 3-4) acute graft versus host disease. * Patients with a history of immunodeficiency (except for acquired hypogammaglobulinemia), patients with active autoimmune disease requiring systemic immunosuppressive therapy (i.e., \> 15 mg of prednisone daily or equivalent), or patients who have received any other form of immunosuppressive therapy within 7 days prior to leukapheresis. * Patients with a history of autoimmune disease resulting in end-organ injury are not eligible unless attributable to primary disease which is target of this study * Patient requires treatment with warfarin. * Patients who have contraindication to the lymphodepletion chemotherapy regimen * Patient received a live vaccine administration within 4 weeks prior to leukapheresis * Patient is currently participating in another investigation treatment study, or has participated in a study of an investigational agent within 4 weeks prior to leukapheresis. * Patients with clinically significant pulmonary dysfunction, as determined by medical history and physical exam should undergo pulmonary function testing; those with a forced expiratory volume at one second(FEV1) of ≤ 65% or diffuse capacity lung for carbon monoxide (DLCO; corrected) \< 40% will be excluded * Patients with history of other active malignancy within 1 year prior to enrollment. * Patients with adequately resected basal or squamous cell carcinoma of the skin, non-melanoma skin cancer or carcinoma in situ (e.g., skin, cervix, bladder, breast), superficial bladder cancer, asymptomatic localized low grade prostate cancer for which watch-and-wait approach is standard of care, or any other cancer that has been in remission are eligible * History of concomitant genetic syndrome associated with bone marrow failure such as Fanconi anemia, Kostmann syndrome, Shwachman-Diamond syndrome * Known human immunodeficiency virus (HIV) seropositivity or active hepatitis B or C infection. A history of hepatitis B or C is permitted if the viral load is undetectable by quantitative assay * Ongoing uncontrolled serious infection, clinically significant cardiac disease (i.e.,symptomatic congestive heart failure, myocardial infarction, cardiac angioplasty or stenting, unstable angina pectoris, uncontrolled cardiac arrhythmia), poorly controlled pulmonary disease (no clinically significant pleural effusion), or psychiatric illness/social situations that would limit compliance with study requirements within 12 months prior to enrollment. * History of any central nervous system (CNS) disorder such as seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, any autoimmune disease with CNS involvement, posterior reversible encephalopathy syndrome, or cerebral edema * History of symptomatic deep vein thrombosis or pulmonary embolism within 6 months prior to enrollment * CNS lymphoma, untreated CNS metastases, leptomeningeal disease and/or carcinomatous meningitis; patients with a history of brain metastases that are previously treated, stable, and off systemic steroids for over 30 days prior to screening are eligible * Patients that have not recovered from major acute infections and/or recent surgical procedures * Toxicities due to prior therapy must be stable and recovered to ≤ grade 1 (except for clinically non-significant toxicities such as alopecia) * Patients, who in the opinion of the investigator, may not be able to comply with the monitoring requirements of the study
