Lymphoma

This research aims to evaluate the effectiveness and safety of a combination treatment using Selinexor, Pegaspargase, and Dexamethasone for patients with early-stage NK/T-cell lymphoma. The study is designed as a Phase 1 and Phase 2 clinical trial and focuses on improving local disease control and overall prognosis in this specific type of lymphoma. Patients receive an oral regimen combining Selinexor, Pegaspargase, and Dexamethasone. Selinexor works by inhibiting nuclear export proteins that are overexpressed in malignant tumor cells, including viral mRNA such as EBV. This treatment is combined with sequential radiotherapy to potentially enhance outcomes. The study monitors the responses to this combined therapy in early-stage lymphoma. Participants will be involved in regular assessments to track tumor response and overall health. The primary outcome measured is the complete response rate (CRR) based on tumor volume reduction, evaluated up to 36 months from randomization. Safety and treatment effects will be closely monitored during the trial period, which runs from September 2024 through December 2026.

This research aims to understand how patients with cancer respond to COVID-19 vaccination by studying the levels of protective antibodies over time. The focus is on individuals with solid organ malignancies receiving various anti-cancer treatments such as chemotherapy, targeted therapy, and immunotherapy, as well as those who have been disease-free for at least six months. Since cancer patients were excluded from initial vaccine trials, this study seeks to fill knowledge gaps about vaccine safety and effectiveness in this group. Participants include cancer patients who are either undergoing active treatment or are disease-free for six months or more. They are grouped based on their treatment type: chemotherapy, targeted therapy, immunotherapy, or disease-free status. The study involves monitoring antibody trends related to COVID-19 infection and vaccination at multiple time points over a 12-month period. During the study, researchers will collect blood samples to measure neutralizing and spike antibody levels every three months for up to one year. Participants will be followed to track their immune response depending on their cancer treatment and biological aging status. The study will also assess how antibody levels change over time and correlate with different treatments and patient characteristics. Safety and consent are carefully monitored throughout the trial.

Researchers are evaluating the potential usefulness of 18F-FAPI-04 positron emission tomography/computed tomography (PET/CT) and positron emission tomography/magnetic resonance imaging (PET/MR) for diagnosing primary and metastatic cancer lesions, detecting recurrence, and assessing pathological response across various cancer types. The study is observational and aims to assess how well these imaging methods perform compared to standard diagnosis using histopathology and follow-up. Participants with different types of cancer undergo imaging with 18F-FAPI-04 PET/CT and PET/MR scans. The tracer 18F-FAPI-04 is injected into patients before the scans. Tumor uptake is measured by maximum standard uptake value (SUVmax) and tumor to background ratio (TBR). The imaging results are compared using sensitivity, specificity, positive predictive value, negative predictive value, and accuracy to evaluate diagnostic performance. During the study, participants are assessed through these imaging procedures to monitor tumor presence, recurrence, or response to treatment. The primary outcome is the diagnostic performance evaluated over one year. The study includes participants aged 18 to 90 years and involves informed consent and ethical approval. The total duration and follow-up details are based on imaging and clinical evaluations to confirm findings.

Researchers are evaluating the use of 18F-Pentixafor PET imaging to improve the diagnosis, staging, and response evaluation of hematological malignancies such as multiple myeloma, leukemia, and lymphoma. This imaging method targets the CXCR-4 receptor, which is overexpressed in these tumors and is linked to tumor growth and poor prognosis. The study aims to assess how well 18F-Pentixafor PET performs compared to current imaging methods like 18F-FDG PET. Participants will receive a single intravenous injection of 18F-Pentixafor at a dose of 55 MBq/kg. After 60 minutes, they will undergo either a PET/CT or PET/MR scan. This process allows for detailed imaging without special preparation. The study includes patients with suspected or confirmed hematological malignancies and involves only one imaging session per participant. During the study, researchers will monitor diagnostic accuracy and compare 18F-Pentixafor PET's performance with traditional 18F-FDG PET imaging. They will also assess disease activity using the Deauville Score over a period of up to 3-4 years. Participants will be involved in imaging procedures and may undergo biopsies if needed for diagnosis. The study will continue until December 2029, with an average follow-up of about 1.5 years for primary outcome assessment.

Researchers are evaluating the side effects and optimal dose of a radioactive antibody agent called 211At-BC8-B10 in combination with donor stem cell transplant for patients with high-risk acute leukemia or myelodysplastic syndrome that has relapsed or is not responding to treatment. This phase I/II study aims to understand how 211At-BC8-B10, a monoclonal antibody that may affect cancer cell growth, works alongside chemotherapy, total body irradiation, and stem cell transplant to treat these conditions. Participants receive a preparative regimen including an infusion of 211At-BC8-B10 over 6 to 8 hours, followed by fludarabine and cyclophosphamide given intravenously on specific days, and total body irradiation before transplant. On transplant day, patients undergo peripheral blood stem cell or bone marrow transplant. After transplant, patients are given medications cyclophosphamide, mycophenolate mofetil, and tacrolimus to reduce the risk of graft versus host disease. They also receive granulocyte colony-stimulating factor until their white blood cell counts recover. During the study, participants have bone marrow biopsies, aspirations, and blood samples collected to monitor their condition. Follow-up visits occur at 100 days, and at 6, 9, 12, 18, and 24 months after treatment. Researchers measure outcomes such as serious toxic side effects, remission rates, engraftment success, donor cell presence, immune recovery, graft versus host disease, survival, and disease-free survival. The study is sponsored by the Fred Hutchinson Cancer Center and includes adults aged 18 to 75 years.

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 formulation of 64Cu-LLP2A, a drug used with PET/CT imaging, to study its dosimetry and imaging quality in healthy volunteers and patients with certain blood cancers. These cancers include multiple myeloma and various low-grade lymphomas. This early phase 1 study aims to confirm that the new formulation provides similar human dosimetry to previously published results and to expand evaluation to patients with confirmed diagnoses or those post bone marrow transplant with suspected recurrence. Participants will receive 64Cu-LLP2A followed by PET/CT imaging at up to three separate times depending on the injection day of the week. Imaging sessions involve multiple quick body scans within the first hour, additional scans between 120 to 240 minutes, and a later scan 15 to 28 hours post injection. Patients with known lesions will have dynamic imaging centered over those areas for one hour, plus an additional scan from head to upper thigh after injection. During the study, participants will undergo PET/CT scans and monitoring of organ dosimetry and safety for up to seven days after 64Cu-LLP2A administration. Researchers will assess the quality of PET images by looking at bone marrow uptake and tumor-to-background ratios. Safety will be tracked by recording any adverse events. The total imaging and evaluation period is estimated to last up to two days, with additional follow-up phone assessments.

This research aims to evaluate the use of a new imaging agent called 68Ga-ICAM-1pep in cancer patients undergoing radiotherapy. Researchers want to see if this agent can help predict the abscopal effect, a phenomenon where radiotherapy affects tumors outside the treated area. The study focuses on patients with various cancers such as lung, esophagus, and cervical cancer, and it is an early-phase clinical trial investigating this new approach. Participants will receive a single intravenous dose of 2.96 MBq/kg of 68Ga-ICAM-1pep. PET/CT scans will be performed about one hour after the injection. There are two groups: patients who have not yet received radiotherapy and those who have completed radiotherapy. Imaging will be done before and during radiotherapy to observe tumor responses. During the study, participants will undergo PET/CT scans covering from the head to the upper thigh. Researchers will measure the standardized uptake values (SUVs) of 68Ga-ICAM-1pep before treatment and monitor changes during radiotherapy, about 3 to 4 weeks after it begins. The study includes monitoring for compliance with imaging procedures and overall safety until the study ends in late 2025.

Researchers are evaluating the uptake characteristics of 68Ga-NYM096 PET/CT imaging in various types of tumors, including both primary and metastatic cancer lesions. This prospective, single-center study aims to provide important insights into how different tumors take up this imaging tracer, helping to identify the most promising uses of 68Ga-NYM096 PET/CT for future cancer diagnosis and treatment assessment. Participants will receive a single intravenous dose of 68Ga-NYM096, with the amount adjusted based on body weight. After injection, a whole-body PET/CT scan will be performed approximately 45 to 75 minutes later to capture detailed images of tumor uptake. The study focuses on quantitative analysis of tracer uptake in cancer lesions, measuring factors such as lesion number, maximum standardized uptake value (SUVmax), and tumor-to-background ratio. During the study, participants will undergo the PET/CT imaging procedure and provide informed consent. Researchers will analyze the images to assess tracer uptake characteristics in confirmed tumors. Safety and compliance with study procedures will be monitored. The main outcome is the quantitative assessment of tumor lesions on the 68Ga-NYM096 PET/CT scan, evaluated from study completion to one month after. The study plans to enroll 120 patients with confirmed cancer diagnoses and will follow ethical guidelines throughout the research.

Researchers are studying the stimulator of interferon gene (STING) protein, which plays an important role in the immune system's ability to detect tumors. This trial focuses on evaluating a new imaging agent called [68Ga]Ga-Sa-DABI-4, designed to noninvasively detect STING expression in the tumor environment using positron emission tomography (PET). The study aims to assess the safety, distribution in the body, and potential usefulness of this imaging agent for cancer patients. Participants will receive one intravenous injection of the investigational drug [68Ga]Ga-Sa-DABI-4 during the study. This single administration is followed by PET imaging to monitor how the agent interacts with the tumor. The study is conducted in an early phase 1 design, focusing on initial safety and diagnostic capabilities. During the trial, participants will undergo PET scans to evaluate the diagnostic effectiveness of the imaging agent within 15 days after injection. Researchers will monitor safety and how the drug distributes throughout the body. The study includes patients suspected of having or newly diagnosed with malignant diseases. Participation involves a single dosing and imaging session, with safety and diagnostic data collected during this period.
