Chronic Lymphocytic Leukemia (CLL)

Researchers are evaluating a new type of CAR T cell therapy called 4SCAR19U T cells for treating patients with CD19-positive B cell malignancies. This phase I trial aims to assess the feasibility, safety, and effectiveness of this universal CAR T cell product in patients who have relapsed or refractory hematological cancers. The study also investigates how these cells function and persist in the body. The trial is sponsored by Shenzhen Geno-Immune Medical Institute and conducted at multiple centers. The 4SCAR19U T cells are genetically engineered and produced in large amounts, allowing them to be stored and used off-the-shelf without needing to be custom-made for each patient. This makes treatment quicker and potentially more accessible, especially for patients with rapidly progressing disease or weakened immune systems after chemotherapy or radiotherapy. Participants will receive infusions of these universal CD19-specific CAR T cells as the investigational therapy. Participants will be monitored for safety over 24 weeks following the infusion to observe any side effects or adverse events. The study will also evaluate the anti-tumor activity of the 4SCAR19U cells for up to one year. Assessments include clinical evaluations, laboratory tests, and tracking of the cells persistence in the body. The trial plans to enroll patients aged from 6 months to 75 years, with specific health and response criteria, and participation could last until the studys end date in 2030.

Researchers are evaluating a new formulation of 64Cu-LLP2A, a drug used for PETCT imaging, in both healthy volunteers and patients with blood cancers such as multiple myeloma and low-grade lymphoma. This early phase study aims to confirm that the new formulation provides comparable human dosimetry to the previous formulation while expanding the patient population to include those with confirmed diagnoses or those who have undergone bone marrow transplant with suspected disease recurrence. Participants will receive the 64Cu-LLP2A drug followed by PETCT imaging at up to three different time points depending on the day of injection. Imaging includes multiple quick body scans shortly after injection, scans at 120-180 or 180-240 minutes post-injection, and a delayed scan 15-28 hours later. Some participants will also undergo a dynamic PETCT scan focused on a known target lesion for 60 minutes, followed by an additional whole-body scan. During the study, participants will be monitored for organ dosimetry and safety through adverse event tracking up to 7 days after administration. The quality of PET images will be assessed based on overall image quality, bone marrow uptake, and tumor-to-background ratios. Participants must lie still within the scanner for up to 75 minutes during imaging sessions. The study is expected to complete by March 2027.

Researchers are studying the safety and effectiveness of GT801 injection in adults who have relapsed or refractory CD19-positive B-cell blood cancers, including acute lymphoblastic leukemia, chronic lymphocytic leukemia, non-Hodgkins lymphoma, and autoimmune hemolytic anemia. This early phase 1 study aims to understand how well the treatment works and its side effects in this group of patients. Participants will receive the GT801 injection as the study treatment. The study focuses on one group receiving this intervention. The treatment schedule and dosing details are not specified, but safety and response to the treatment will be monitored over a period of time, including up to 12 months after infusion. During the study, participants will be closely monitored for side effects and treatment responses through various assessments. Researchers will measure the proportion of participants experiencing dose-limiting toxicity within 28 days and track adverse events up to 3 months after infusion. They will also evaluate overall response rates, duration of response, progression-free survival, and other outcome measures related to both the blood cancers and autoimmune hemolytic anemia for up to 12 months. The study includes regular follow-up visits and evaluations to gather this information.

Researchers are evaluating SCTC21C, a biological treatment, in patients with relapsed or refractory CD38-positive hematologic malignancies. This multicenter, open-label Phase I trial aims to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, preliminary anti-tumor activity, and immune response to SCTC21C. The study includes a dose-finding stage to determine safe dosage levels and a dose-expansion stage to further evaluate selected doses. In the dose-finding stage, participants receive increasing doses of SCTC21C ranging from 0.01 mg up to 960 mg. In the dose-expansion stage, at least 20 participants are randomly assigned in a 11 ratio to receive two different doses determined from the earlier stage. SCTC21C is given by subcutaneous injection weekly for the first two cycles, then every two weeks for cycles three to six, and every four weeks thereafter until disease progression or unacceptable side effects occur. Participants will be closely monitored throughout the study with assessments including safety evaluations, adverse event tracking up to 45 days after the last dose, and measuring dose-limiting toxicities during the first 28-day cycle. Researchers will also evaluate tumor response over about one year of treatment. The study expects participants to have regular visits for treatment and monitoring, with the total duration varying depending on individual response and tolerability.

This observational study focuses on patients aged 18 and older who have lymphoproliferative disorders, a group of blood cancers affecting the lymphatic system. Researchers aim to understand the overall survival over 10 years for different types of these disorders. The study also examines factors like patient fitness, comorbid conditions, and how these influence treatment choices and outcomes. New therapies including chemo-free protocols, targeted drugs, and cell therapies are being evaluated to determine the best treatment sequences for cases that are refractory or relapsed. Participants will be observed through various phases of their disease, including diagnosis and treatment stages. The study investigates the impact of clinical and biological factors on disease progression or relapse, as well as potential links between genetic profiles and clinical outcomes. It also monitors adverse events like tumor lysis syndrome and their effects on treatment adjustments. Additionally, the study looks at patients managed with a watch-and-wait approach, long-term toxicities, secondary cancers, and healthcare resource use. Throughout the study, participants health and treatment outcomes will be regularly assessed using clinical data collected from diagnosis through follow-up. Researchers will analyze survival rates, treatment effectiveness, and side effects over a long period from 2002 to 2030. This comprehensive data collection aims to improve understanding of lymphoproliferative disorders and optimize patient management strategies over time.

Researchers are evaluating BGB-16673, an oral drug, in adults with various types of B-cell malignancies such as marginal zone lymphoma, follicular lymphoma, mantle cell lymphoma, chronic lymphocytic leukemia, Waldenstrm macroglobulinemia, diffuse large B-cell lymphoma, and Richters transformation. This study includes Phase 1 dose finding and safety expansion, followed by Phase 2 expansion cohorts to determine recommended doses and further assess safety and efficacy. The study is divided into several parts, starting with Phase 1 dose escalation to find safe dosage levels, including monotherapy dose escalation and safety expansion in selected doses. Phase 2 involves expansion cohorts where participants receive the recommended doses identified in Phase 1 for further safety and efficacy evaluation. Some cohorts include participants who have not received prior BTK inhibitors, and Japanese participants are also enrolled to assess safety. Treatments are orally administered. Participants will undergo regular assessments including monitoring for adverse events, disease response, and drug concentration levels in the blood at various time points. Researchers will measure outcomes such as overall response rate and progression-free survival over approximately three years. Safety and tolerability will be closely tracked, and quality of life questionnaires will be completed at scheduled intervals. Participation may last several years, including follow-up periods to monitor long-term effects.

This research aims to gather long-term safety and effectiveness information for people treated with ibrutinib, a medicine taken by mouth that blocks a specific enzyme called brutons tyrosine kinase. The study focuses on participants who previously took part in ibrutinib studies that have finished and are still receiving ibrutinib treatment, continuing to benefit from it. It is an open-label study, meaning both participants and researchers know the treatment being given. Participants will continue taking ibrutinib capsules daily at the dose they were given in their prior study until the doctor decides the treatment is no longer helpful due to disease progression or side effects, the participant chooses to stop, other treatment options become available, or the study ends. Safety will be monitored throughout, and effectiveness data may be combined with previous study results. No formal testing of hypotheses is planned in this extension. During the study, participants will be regularly monitored for safety and disease status. The main outcome is the number of participants experiencing side effects within 30 days after the last ibrutinib dose or before starting another cancer therapy. Participants may continue treatment until alternative access to ibrutinib is arranged or the study ends, which is planned for December 2029. Researchers will collect ongoing data to understand the long-term effects of ibrutinib treatment.

Researchers are conducting a master protocol study to evaluate the long-term safety and efficacy of the drug pirtobrutinib in patients who have completed previous clinical studies involving this medication. This study includes participants with chronic lymphocytic leukemia or non-Hodgkin lymphoma and aims to monitor their health over an extended period. The master protocol organizes individual study-specific appendices ISAs representing participants from earlier originator studies. Participants continue to receive pirtobrutinib as they did in their original clinical study, with the drug administered orally. The study allows these individuals to keep taking the treatment or to continue with follow-up visits under this master protocol framework. The study is designed to gather safety and survival data over many years. During the study, participants will be closely monitored for any serious treatment-related side effects, with assessments focused on adverse events occurring from the first dose until shortly after the last dose or when starting a new anticancer therapy. Researchers will also track overall survival for up to 93 months. This long-term follow-up ensures comprehensive safety and health evaluations throughout the participants involvement, which may last several years.

Researchers are investigating a new combination of three drugsazacitidine, venetoclax, and tagraxofuspto treat patients with Acute Myeloid Leukemia AML who have leftover leukemia cells that cannot be seen with the naked eye. This Phase 12 clinical trial aims to assess the safety and how well this drug combination controls residual AML and prevents the disease from coming back. The study builds on FDA approvals of venetoclax and azacitidine together for AML and tagraxofusp alone for another leukemia type, but this combination is not yet FDA-approved for AML treatment. The study involves two groups of participants. In Phase 1, up to 12 people receive escalating doses of tagraxofusp combined with fixed doses of azacitidine and venetoclax to find the safest and best dose. Treatment cycles last 28 days, with azacitidine given daily for seven days, tagraxofusp infused on days 4 to 6, and venetoclax taken on days 1 and 14. In Phase 2, 19 participants receive the recommended dose of tagraxofusp plus azacitidine and venetoclax with the same schedule. Bone marrow biopsies and aspirations occur regularly during treatment to monitor response. After treatment, participants are followed for up to two years. Participants will have regular visits including blood tests, imaging scans like CT, MRI, or PET, heart function tests, and bone marrow examinations. Researchers will monitor for side effects, measure disease remission, and check for minimal residual disease to evaluate treatment impact. The study expects to last about four years with around 31 participants. Outcomes such as remission duration, survival, relapse rates, and safety events will be assessed during treatment and follow-up.

This research aims to understand how well routine childhood vaccinations protect pediatric patients under 21 years old who have been treated for B-cell Acute Lymphoblastic Leukemia or Lymphoma B-ALLLy, especially those who have received the immunotherapy drug blinatumomab. The study compares patients treated with blinatumomab to those who have not, to see if immunotherapy affects the lasting protection from vaccines. It also seeks to establish clear vaccination guidelines for these patients, since chemotherapy and immunotherapy may weaken their immune defenses. Participants are observed in two groups those who have received blinatumomab and those who have not. The study evaluates whether patients maintain protective antibody levels at least six months after completing blinatumomab therapy. For patients with low immunity, the study will assess if revaccination restores protective antibody levels within six months. The study does not involve new treatments but monitors immune responses over time to routine vaccinations. During the study, participants will have blood tests to measure their antibody levels against common vaccine-preventable diseases. Researchers will track who maintains immunity and who responds to revaccination. The primary measurement is the proportion of patients with protective antibody levels six months post-treatment. The study will continue to monitor participants immune status and response to boosters, helping to inform future vaccination protocols. Participation may last through follow-up visits over several months after therapy completion.
