Propranolol With Tislelizumab Plus GC in Neoadjuvant Bladder UC

Bladder Urothelial Carcinoma Lymph Node Metastasis

This is a prospective, multicenter, Phase Ib clinical study designed to evaluate the safety and preliminary efficacy of propranolol combined with tislelizumab plus gemcitabine/cisplatin (GC) as neoadjuvant therapy for patients with bladder urothelial carcinoma with clinical lymph node involvement (cT1-T4aN1-3M0). Current neoadjuvant immunochemotherapy regimens can improve clinical outcomes in cisplatin-eligible patients; however, patients with lymph node metastasis show a significantly poorer pathological complete response (pCR) rate compared with non-metastatic cases. Real-world clinical observations have shown that more than 20% of patients achieve complete response in the primary tumor after immunotherapy but have persistent or progressive positive lymph nodes, suggesting unique resistance mechanisms within lymph node metastatic lesions. Preclinical studies conducted by our team demonstrated that sympathetic innervation within lymph nodes releases norepinephrine, which activates β-adrenergic signaling in metastatic tumor cells and promotes lipid metabolic reprogramming, leading to CD8⁺ T-cell exhaustion and immune resistance. Propranolol, a non-selective β-adrenergic blocker, may reduce metabolic stress and restore antitumor immunity, potentially enhancing the efficacy of immune checkpoint blockade. In this study, enrolled patients will receive oral propranolol in combination with intravenous tislelizumab and standard GC chemotherapy prior to surgery. Participants will be closely monitored for treatment-related adverse events, including cardiovascular events, hematologic toxicity, and immune-related reactions. The primary endpoint is dose-limiting toxicity (DLT). Secondary endpoints include pathological complete response (pCR), pathological downstaging, safety, and survival outcomes. Exploratory analyses will evaluate changes in immune cell populations in tumor tissues, lymph nodes, and peripheral blood. The results of this study aim to provide evidence for new neoadjuvant strategies targeting lymph node metastatic bladder cancer and support the development of personalized therapeutic approaches.

The Effects of a Nurse-led TGA-based Pre-rehabilitation Planning on Perioperative Outcomes in Patients With Liver Cancer: Study and Protocol

Liver Cancer

The goal of this clinical trial is to to learn if the nurse-led TGA-based Pre-rehabilitation planning can improve compliance, preoperative functional reserve, and reduce the incidence of postoperative complications in patients with hepatocellular carcinoma. The main questions it aims to answer are: 1. Can this pre-rehabilitation program improve patients' perioperative motor function? 2. Can this pre-rehabilitation program enhance patients' perioperative nutritional status? 3. Can this pre-rehabilitation program improve patients' psychological state? 4. Can this pre-rehabilitation program increase patients' overall compliance? Meanwhile, secondary outcome indicators included complication incidence rate, 30-day readmission rate, first anal flatus passage time, hospitalization duration, serum prealbumin, serum albumin, prothrombin time, total bilirubin, satisfaction and quality of Life. Researchers will compare the control group received only ERAS care after the patient's admission to see if the program is effectiveness. Participants who received the intervention group protocol will initiate pre-rehabilitation measures more than 7 days prior to hospital admission, including nutritional support, exercise and respiratory function training, psychological empowerment, pain pre-management, and smoking/alcohol cessation. These interventions will be recorded daily according to the achievement thresholds established by the research team based on outpatient assessment results. After admission, the patients in this group will receive the same EARS care as the control group.

Gene Therapy Follow up Protocol for Subjects Previously Enrolled in NCI Center for Immuno-Oncology Studies

Cervical Intraepithelial Neoplasia Cervical Neoplasms Oropharyngeal Neoplasms Squamous Intraepithelial Lesions of the Cervix +1

Background: Gene therapy is closely followed by the U.S. Food and Drug Administration (FDA). The FDA requires researchers to conduct long-term follow-up of people who have had the treatment. This study collects data on people who have had gene therapy and sends it to the FDA. The data does not include participants names. Objective: To contact current or past participants of gene therapy protocols at least once a year for up to 15 years to ensure they have not had any harmful side effects. Eligibility: People aged 18 and older who have had gene therapy in a National Cancer Institute study Design: Participants will give their address and telephone number. They will also give and the address and phone number of 1 or 2 other people who will know where they are. For the first year after gene therapy, participants will give blood samples 3 times (at 3, 6, and 12 months). For the next 4 years, they may have a physical exam and laboratory tests with a home physician. They will get a kit to mail in blood samples. Or they can visit the NIH Clinical Center. They will be asked if they have had any signs of neurological, autoimmune, or blood disorders, or any new cancers. For years 6 to 15, participants will be contacted yearly via phone or email and asked questions about their health. They may give blood samples. When the participant dies, if researchers think the death was caused by gene therapy, they will ask the participant s family to allow an autopsy. ...

Leukapheresis for CAR or Adoptive Cell Therapy Manufacturing

Leukemia Lymphoma Acute Lymphoblastic Leukemia Diffuse Large B Cell Lymphoma +1

Background: Leukapheresis is a procedure to separate and collect white blood cells. It is the first step in a treatment called CAR (chimeric antigen receptor) T-cell therapy. CAR-T therapy may be offered to people when their cancer comes back. The collected T-cells are used to make a special version of T-cells called CARs. Researchers want to collect these cells from people who may become eligible for a CAR T-cell study in the future. Objective: To identify people who have a high likelihood to benefit from CAR T-cell therapy early in their disease course and collect and store a T-cell product. Eligibility: People ages 3-65 with a form of leukemia or lymphoma that has not been cured by standard therapy Design: Participants will be screened with medical history, physical exam, and blood and urine tests. Review of existing MRI, x-ray, pathology specimens/reports or CT images may be done. On this study, participants will have leukapheresis. A needle will be placed into the arm. Blood will be collected and go through a machine. White blood cells will be taken out by the machine. The plasma and red cells will be returned to the participant through a second needle in the other arm. The procedure will take 4-6 hours. Some participants may have a central line (catheter) inserted which is needed to do the leukapheresis procedure, instead of the needles in the arms-especially if they are smaller. For a central line placement, a long thin tube is inserted through a small incision into the main blood vessel leading into the heart that would allow access to the blood to do the leukapheresis procedure. Participants cells will be processed and frozen for future use in a CAR T-cell therapy study.
