Researchers are studying the use of 3'-deoxy-3'-[18F] fluorothymidine (FLT) positron emission tomography (PET) imaging in patients with cancer. This phase I trial aims to evaluate how well FLT PET imaging measures tumor growth and the activity of the DNA synthetic pathway in various cancers, including solid tumors and blood cancers. The study also seeks to determine how effective this imaging method is at detecting lesions and assessing response to treatment. Participants receive up to four FLT PET imaging procedures. During each procedure, a small amount of the FLT tracer compound is injected into the vein, followed by PET scan data collection for two hours to measure tumor growth. Blood samples may be taken during the scans, and urine samples collected afterward to analyze breakdown products of the tracer. Throughout the study, patients undergo assessments including PET or CT PET scans to measure tracer uptake and retention in tumors and normal organs. Researchers also evaluate changes in key enzymes related to DNA synthesis before and after therapy. These evaluations help monitor tumor activity and treatment response. The total time participants spend in the scanner during imaging is up to two hours per session, with a focus on capturing detailed tumor growth information.

Researchers are evaluating a new universal CAR T cell therapy called 4SCAR19U for patients with CD19-positive B cell malignancies. This phase I trial aims to assess the feasibility, safety, and effectiveness of these specially engineered T cells. The study also seeks to understand how well the 4SCAR19U T cells function and how long they remain active in patients. This approach may offer a faster, more cost-effective alternative to traditional CAR T therapies, especially for patients with weakened immune systems or rapidly progressing disease. The treatment involves infusing patients with universal CD19-specific CAR gene-engineered T cells known as 4SCAR19U cells. These cells are manufactured in bulk and ready to use off-the-shelf, avoiding the long preparation time required for patient-specific therapies. This immediate availability aims to provide timely treatment to patients who need it urgently. The trial is conducted at multiple clinical centers and includes one experimental group receiving the 4SCAR19U cell infusion. Participants will be monitored closely for safety over 24 weeks following the infusion, with evaluations of adverse effects and overall health. The study will also track the anti-tumor activity of the 4SCAR19U cells for up to one year after treatment. Assessments include physical exams, blood tests, and other clinical evaluations to understand the treatment's impact and cell persistence. The total duration of involvement varies, with long-term follow-up to gather important safety and effectiveness data.

Researchers are studying the use of [90Y]Y-PentixaTher ([90Y]Y-PTT) to treat patients with recurrent or refractory primary or isolated secondary central nervous system (CNS) lymphoma. This open-label, single-arm phase 1/2 study aims to evaluate the safety, tolerability, biodistribution, and preliminary effectiveness of this treatment. The study includes three dose-level groups, and a safety review committee will carefully monitor for any dose-limiting side effects to guide dose adjustments. Participants will receive one cycle of [90Y]Y-PTT administered intravenously. The study follows a best-of-5 dose escalation design across three cohorts with different dose levels. There is no comparison group in this study. After the treatment, patients will undergo several visits during the core study phase to assess safety, how the drug spreads in the body, dosimetry, and treatment response. Following this, three follow-up visits will occur at three-month intervals to monitor disease status. Throughout the study, participants will be closely monitored for adverse events, with severity graded by standard criteria. Various imaging and laboratory tests will be performed shortly after infusion and at multiple time points to measure drug uptake in tumors and organs, blood levels, and absorbed radiation doses. Researchers will assess response rates, progression-free survival, and overall survival at one, three, six, nine, and twelve months after treatment. The total study duration includes screening, treatment, core evaluations, and extended follow-up visits to comprehensively evaluate treatment outcomes and safety.

Researchers are evaluating CT1182, an in vivo CAR-T cell therapy, in patients with relapsed or refractory B-cell Non Hodgkin Lymphoma (r/r B-NHL). This early phase 1, open-label study aims to explore the safety, effectiveness, metabolic behavior, and pharmacodynamics of CT1182 cells. The study intends to identify the maximum tolerated dose (MTD) by testing four dose levels, with a target toxicity probability of 30%, to understand how the treatment affects patients with various subtypes of B-NHL. Participants will receive intravenous infusions of CT1182 at escalating dose levels ranging from 1.2 × 10^8 to 1.2 × 10^9 TU. The dose escalation follows a Bayesian Optimal Interval design, with safety monitored over a 28-day dose-limiting toxicity (DLT) observation period after the first infusion. If no DLT is observed, doses may be adjusted; if ineffective expansion of CAR-T cells is detected, early withdrawal or continued safety observation is possible. The study plans to enroll between 3 and 24 participants, with dosing and cohort size adjusted according to ongoing results. During the study, participants will be closely monitored for adverse events, DLTs, and response rates for up to 24 months after infusion. Evaluations include clinical assessments, laboratory tests, and measurement of CAR gene copy numbers at multiple timepoints. Outcome measures include safety profiles, objective and complete response rates, duration and time to remission, progression-free survival, overall survival, and metabolic kinetics of the lentiviral vectors used in treatment. The study follows participants through long-term safety and efficacy assessments to better understand CT1182's impact.

Researchers are evaluating the safety and effectiveness of an investigational treatment called RN1101, which are allogeneic CAR-T cells targeting CD19 and BCMA. This early-phase, open-label pilot study focuses on patients with relapsed or refractory B-cell or plasma cell-derived malignant tumors, including B-cell lymphoma and multiple myeloma. The study plans to enroll 21 patients to understand how well this treatment works and its safety profile for these challenging cancers. Participants will receive a single intravenous infusion of RN1101 cells designed to target and attack cancerous B cells or plasma cells. The study involves a dose-escalation approach where all patients receive the experimental therapy. Researchers will monitor the treatment's ability to reduce or eliminate cancer cells expressing CD19 or BCMA and evaluate how long these CAR-T cells persist in the body. Throughout the study, participants will be closely followed for up to 24 weeks after the infusion. Researchers will assess safety by tracking adverse events and measure effectiveness using outcomes such as minimal residual disease status, response rates, progression-free survival, overall survival, and CAR-T cell presence in blood and bone marrow. Blood tests, imaging, and clinical evaluations will be performed regularly to monitor treatment response and participant health over this period.

Researchers are evaluating the safety and effects of MK-1045 in people with two types of non-Hodgkin lymphoma (NHL): follicular lymphoma (FL), which grows slowly, and diffuse large B-cell lymphoma (DLBCL), which grows quickly. NHL is a cancer affecting the lymphatic system, causing swollen lymph nodes. This study aims to see if MK-1045, an immunotherapy that helps the immune system fight cancer, is safe and tolerated, and whether it can reduce or eliminate these lymphomas. Participants will be randomly assigned to one of four groups. Each group will receive MK-1045 at different dosages and by different methods: intravenous (IV) infusion or subcutaneous (SC) injection. Treatment will last for up to about one year or until the participant stops treatment. The study includes groups focusing on FL with dose optimization or longer dosing intervals, one group receiving SC administration, and one group focusing on DLBCL with dose optimization. During the study, researchers will monitor participants for adverse events and treatment effects using the Lugano Response Criteria. They will also measure drug levels in the blood at various times up to 12 months. Participants will be followed for up to approximately 44 months to assess safety, response duration, and treatment tolerability. Tumor tissue samples and other clinical data will be collected to support these evaluations throughout the trial.

Researchers are evaluating treatments for germinal center B-cell-like diffuse large B-cell lymphoma (GCB DLBCL), a fast-growing blood cancer affecting immature B-cells. This phase 2 study compares the effects of zilovertamab vedotin combined with R-CHP chemotherapy versus polatuzumab vedotin combined with R-CHP in people newly diagnosed with this type of lymphoma. The goal is to see if the cancer responds better to one treatment over the other. Participants will be randomly assigned to receive either zilovertamab vedotin or polatuzumab vedotin, both given by intravenous infusion on the first day of each 3-week cycle for up to six cycles (about 4 months). Alongside these drugs, participants will receive cyclophosphamide, doxorubicin, and rituximab or a rituximab biosimilar by IV infusion, plus prednisone or prednisolone orally for five days each cycle. Those with high-risk DLBCL may receive two additional cycles of rituximab or its biosimilar. During the study, participants will have scans and tests to measure cancer response using established criteria over up to 31 months. Researchers will also monitor survival rates, quality of life, and side effects for up to several years. Safety assessments and treatment adherence will be tracked throughout the study and follow-up periods, ensuring thorough evaluation of each treatment's impact.

Researchers are evaluating the efficacy and safety of TQB3702 tablets combined with immunochemotherapy for treating B-cell lymphoma. This Phase II clinical trial focuses on patients diagnosed with specific types of B-cell lymphoma, including relapsed or refractory indolent B-cell lymphoma and diffuse large B-cell lymphoma (DLBCL). The study aims to assess how well this combination therapy works and its overall safety. Participants will receive TQB3702 tablets at a dose of 200 mg every 4 weeks as one treatment cycle. Alongside this, they will undergo chemotherapy cycles every 3 or 4 weeks, with a total of 6 to 12 cycles of combination therapy. The chemotherapy regimen is designed to inhibit tumor cell growth, suppress DNA synthesis, induce cancer cell death, support immune function, and prevent new blood vessel formation that supports tumors. During the trial, participants will be closely monitored for treatment response and safety. Researchers will measure overall and complete response rates up to 2 years, as well as adverse events, progression-free survival, duration of response, and overall survival up to death from any cause. The study includes assessments from baseline through combination therapy completion and follow-up periods lasting up to 2 years. This comprehensive monitoring helps understand both the immediate and longer-term effects of the treatment.

Researchers are evaluating the safety and activity of ADX-2191 (methotrexate injection USP) given directly into the eye for patients with primary vitreoretinal lymphoma. This Phase 3, multicenter, randomized, double-masked clinical trial compares different dosing schedules to understand how well they clear lymphoma cells from the eye. Participants will receive one of two treatment methods after developing lymphomatous vitreous cells in at least one eye. One group will follow the Induction/Consolidation/Maintenance (ICM) dosing of ADX-2191, receiving intravitreal injections twice weekly for four weeks, then weekly for eight weeks, totaling sixteen injections. The other group will receive monthly ADX-2191 injections for three months, with sham injections during other visits for a total of thirteen sham injections. During the study, participants will be monitored for the clearance of lymphoma cells in the eye over eight weeks. The main measure is the proportion of patients whose vitreous cells clear after treatment. Safety and response will be assessed through regular visits and evaluations. The trial will continue until December 2026, with all study-related care provided under careful observation.

Researchers are evaluating ONM-501, a drug given as intratumoral injections, alone and in combination with cemiplimab, an immune checkpoint inhibitor, in patients with advanced solid tumors and lymphomas. This phase 1 study aims to find the maximum tolerated dose, minimum effective dose, and recommended dose for expansion of ONM-501. The study includes patients with various advanced cancers who have no alternative standard therapies available. The trial has three parts: monotherapy dose escalation, combination therapy dose finding, and combination therapy dose expansion. ONM-501 is given once per week for three weeks followed by three weeks off, in 21-day cycles. Cemiplimab is given intravenously every three weeks during the combination phases. Dose escalation uses special methods to gradually increase doses, and after doses are established, patients will enroll in expansion cohorts for specific tumor types. Participants will have regular assessments including monitoring for side effects, blood tests to measure drug levels, and evaluation of tumor response over up to 24 months. Researchers will track treatment-emergent adverse events, dose-limiting toxicities, and serious adverse events. Outcomes such as objective response rate, duration of response, progression-free survival, and overall survival will also be recorded. The study involves close safety monitoring and follow-up throughout the treatment and observation periods.
