An Open-label Dose Escalation Study to Evaluate Safety, Tolerability, Biodistribution and Efficacy of [90Y]Y-PentixaTher for the Therapy of Recurrent or Refractory Primary or Isolated Secondary Central Nervous System Lymphoma.

This will be an open-label, single-arm, national phase 1/2 therapeutic study to evaluate the safety, tolerability, and preliminary efficacy of [90Y]Y-PentixaTher ([90Y]Y-PTT) for the treatment of recurrent or refractory primary or isolated secondary central nervous system (CNS) lymphoma. The study will be performed in three cohorts with different dose levels (2, 4 and 6 GBq) according to the best-of-5 dose escalation design. A safety review committee (SRC) will evaluate dose-limiting toxicities and decide about escalation and de-escalation. Eligible patients will receive one cycle of [90Y]Y-PTT, which will be administered intravenously. There will be no comparator in this study. Safety, biodistribution, dosimetry and efficacy will be evaluated during the core study phase (Visit 1 until Visit 5). Thereafter three follow-up (FU) visits will take place, at three-months intervals to evaluate the extent of disease.

Iomab-ACT: A Pilot Study of 131-I Apamistamab Followed by CD19-Targeted CAR T-Cell Therapy for Patients With Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia or Diffuse Large B-Cell Lymphoma

This is a single-cohort pilot study; patients will receive 131-I apamistamab 75 mCi prior to CAR T-cell infusion in order to determine the maximum tolerated dose of 131-I apamistamab.

An Open-Label, Multicenter, Phase 2 Study of Iopofosine I 131 (CLR 131) in Patients With Relapsed or Refractory (R/R) Select B-Cell Malignancies (CLOVER-1) and Expansion Cohort in Patients With Waldenstrom Macroglobulinemia (CLOVER-WaM)

Part A of this study evaluates iopofosine I 131 (CLR 131) in patients with select B-cell malignancies (multiple myeloma( MM), indolent chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL), lymphoplasmacytic lymphoma (LPL)/Waldenstrom Macroglobulinemia (WM), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), diffuse large B-cell lymphoma (DLBCL), and central nervous system lymphoma (CNSL) who have been previously treated with standard therapy for their underlying malignancy. Part B (CLOVER-WaM) is a pivotal efficacy study evaluating IV administration of iopofosine I 131 in patients with WM that have received at least two prior lines of therapy.

Evaluation of the Fractional Uptake Rate (FUR) in 18F-FDG PET/CT to Assess Tumour Metabolic Activity

The goal of this study is to evaluate the use of new method to quantify the amount of sugar a tumor consumes using PET/CT. The main questions it aims to answer are: Is the new quantification method superior with respect to the method currently used in the clinic? Does the new quantification method provide accurate assessment of the sugar consumption of tumours? Participants who will undergo a standard care FDG PET/CT scan will in additional receive a dynamic PET/CT scan prior to the standard care scan. In addition blood samples will be drawn at three time points during the examination.

FDG PET Evaluation for Marginal Zone Lymphoma and Its Prognostic Role: an International Multicenter Retrospective Analysis

The study will be conducted on performed scans. No additional scan or procedure will be required for study purposes. The study will be divided into two sections with different aims: Part A will be conducted to understand the role of PET for the staging of MZL. PET scans will be analyzed and compared with data retrieved from CT scan and from other staging procedures, also including bone marrow biopsy, ultrasound, and laboratory exams. This part of the study will describe ability of PET to identify pathologic lesions and to contribute to staging definition or to stage migration. Part B will be conducted to validate standardized criteria for response assessment in MZL including FDG-PET among procedures and to define the prognostic role of metabolic response in MZL. For this purpose the primary endpoint for this part of the study is defined as the progression free survival. Secondary endpoint will be Overall survival, and response rate defined with conventional procedures and rate of histological transformation.

18F-FDG PET Scan and MRI Diffusion : Correlation Study of the Evaluation of the Early Therapeutic Response of Diffuse Large B-cell Lymphoma

Open-label, multicenter, uncontrolled and non-randomized study comparing 18F-FDG PET-Scan and diffusion MRI in the assessment of the early therapeutic response of Diffuse Large B-Cell Lymphoma.

A Phase I Study: PET Imaging of Cancer Patients Using [18F] 4-L-Fluoroglutamine (2S,4R)

This is a Phase I study. This study is the first time that a new experimental drug called 18FFluoroglutamine, or F-Glutamine, is being used in people. F-Glutamine is a drug designed to be used with PET scanners that can 'see' where F-Glutamine goes in the body, after its injected. PET scanners are one of the kinds of scanners you normally find in a hospital radiology department. The researchers have found that tumors in animals absorb F-Glutamine. The researchers believe that scans with F-Glutamine might be able to find tumors in patients. This first in-human study is being done to see how long F-Glutamine lasts in the blood, when it is given to people in tiny amounts by an injection, and to see where F-Glutamine goes in the body. If the results of this trial are good, then the study doctors plan to use F-Glutamine in another trial to see if scans with F-Glutamine are better for finding tumors compared to the standard types of scans that doctors use.
